Prospectus Supplement
(to Prospectus dated June 27, 2024)
1,592,356 Common Shares
1,592,356 Series A Warrants to Purchase 1,592,356 Common
Shares
796,178 Series B Warrants to Purchase 796,178 Common Shares
We are offering 1,592,356 of our common shares, without par value (“Common Shares”), 1,592,356 associated warrants to purchase an aggregate of 1,592,356 Common Shares (“Series A Public
Warrants”), and 796,178 associated warrants to purchase an aggregate of 796,178 Common Shares (“Series B Public Warrants”, each one Series A Public Warrant and one-half of one Series B Public Warrant, a “Public Warrant”, and collectively, the “Public Warrants”). This prospectus supplement also relates to the offering
of Common Shares issuable upon exercise of the Public Warrants.
Our
Common Shares trade on the Nasdaq Global Market under the symbol “NB.” On October 31, 2024, the last reported sale price
of our Common Shares on the Nasdaq Global Market was $1.82 per Common Share. There is no established trading market for the Public Warrants and
we do not expect a market to develop. In addition, we do not intend to list the Public Warrants on any national securities exchange or any other
nationally recognized trading system.
In
a concurrent private placement (the “Concurrent Private Placement”), we also expect to sell to certain investors an aggregate
of 2,199,888 Common Shares, associated warrants to purchase up to an aggregate of 2,199,888 Common Shares (“Series A Private Warrants”), and associated warrants to purchase up to an aggregate of 1,099,944 Common Shares (“Series B Private Warrants”, and collectively with the Series A Private Warrants, the “Private Warrants”).
These Common Shares, Private Warrants and the Common Shares issuable upon exercise of the Private Warrants are being offered pursuant
to the exemption provided in Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities Act”), and/or
Rule 506(b) promulgated thereunder and are not being registered under the Securities Act at this time or offered pursuant to this prospectus
supplement and the accompanying prospectus. Our Chief Executive Officer, President and Executive Chairman, Mark Smith, and one of our
directors, Dean Kehler, have indicated an interest in purchasing an aggregate of approximately $350,000 of our Common Shares and associated
Private Warrants in the Concurrent Private Placement. However, Mr. Smith and Mr. Kehler are not obligated to purchase any Common Shares
and associated Private Warrants and may determine to purchase fewer or more Common Shares and associated Private Warrants than they indicated
an interest in purchasing or none at all.
Investing in our securities involves a high
degree of risk. See “Risk Factors” beginning on page S-5 of this prospectus supplement and on page 2 of the
accompanying prospectus, and the documents incorporated by reference herein and therein.
Neither the Securities and Exchange Commission
(the “SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this prospectus
supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

if any, of $1.55 Option Share and/or (ii) 358,280 Option Warrants (as defined below) to purchase up to an aggregate of 358,280 Common
Shares (equal to 15% of the aggregate number of initial Public Warrants offered hereby) at a purchase price, before giving effect to applicable
underwriting discounts and commissions, if any, of $0.02 per Option Warrant. “Option Warrant” means one Series A Public Warrant
combined with one-half of one Series B Public Warrant. If the underwriter exercises the over-allotment option to purchase Option Shares
and Option Warrants in full, without giving effect to the exercise of any Public Warrants, the total proceeds to us, before expenses payable
by us, will be approximately $374,999, assuming no sales to persons on the President’s List or to any person who is a director or
officer of the Company.
The securities are expected to be delivered on
or about November 5, 2024.

About the Company
NioCorp Developments Ltd.
NioCorp is
developing the Elk Creek Project (as defined below) located in southeast Nebraska. The “Elk Creek Project” is a development-stage
property that has disclosed niobium, scandium, and titanium reserves and resources and disclosed rare earth mineral resources. The Company
is continuing technical and economic studies around the rare earths contained in the Elk Creek Project’s mineral resource in order
to determine whether extraction of rare earth elements can be reasonably justified and economically viable after taking into account all
relevant factors. Niobium is used to produce various superalloys that are extensively used in high performance aircraft and jet turbines.
It also is used in high-strength, low-alloy steel, a stronger steel used in automobiles, bridges, structural systems, buildings, pipelines,
and other applications that generally increases strength and/or reduces weight, which can result in environmental benefits, including
reduced fuel consumption and material usage and fewer air emissions. Scandium can be combined with aluminum to make high-performance alloys
with increased strength and improved corrosion resistance. Scandium also is a critical component of advanced solid oxide fuel cells, an
environmentally preferred technology for high-reliability, distributed electricity generation. Titanium is a component of various superalloys
and other applications that are used for aerospace applications, weapons systems, protective armor, medical implants, and many others.
It also is used in pigments for paper, paint, and plastics. Rare earths are critical to electrification and decarbonization initiatives
and can be used to manufacture the strongest permanent magnets commercially available.
Our primary business strategy is to advance our Elk Creek Project to commercial production. We are focused on obtaining additional funds to carry out our near-term planned work programs associated with securing the project financing necessary to complete mine development and construction of the Elk Creek Project.

The Offering
Securities Offered by this Prospectus Supplement |
1,592,356 common
shares, without par value, of the Company (“Common Shares”), 1,592,356 associated warrants to purchase an aggregate of 1,592,356 Common
Shares (“Series A Public Warrants”), and 796,178 associated warrants to purchase an aggregate of 796,178 Common Shares (“Series B Public Warrants”, each one Series A Public Warrant and one-half of one Series B Public Warrant, a "Public Warrant", and
collectively, the “Public Warrants”). This prospectus supplement also relates to the offering
of Common Shares issuable upon exercise of the Public Warrants. |
|
We
have also granted to the underwriter an over-allotment option to purchase up to (i) 238,853 additional Common Shares (the
“Option Shares”) (equal to 15% of the aggregate number of initial Common Shares offered hereby) at a purchase price,
before giving effect to applicable underwriting discounts and commissions, if any, of $1.55 per Option Share and/or
(ii) 358,280 Option Warrants (as defined below) to purchase up to an aggregate of 358,280 Common Shares (equal to 15% of
the aggregate number of initial Public Warrants offered hereby) at a purchase price, before giving effect to applicable
underwriting discounts and commissions, if any, of $0.02 per Option Warrant. “Option Warrant” means one Series A
Public Warrant combined with one-half of one Series B Public Warrant. |
Concurrent Private Placement |
In
a concurrent private placement (the “Concurrent Private Placement”), we also expect to sell to certain investors (the “Private
Investors”) an aggregate of 2,199,888 Common Shares, associated warrants to purchase
up to an aggregate of 2,199,888 Common Shares (“Series A Private Warrants”),
and associated warrants to purchase up to an aggregate of 1,099,944 Common Shares
(“Series B Private Warrants”, and collectively with the Series A Private Warrants, the “Private Warrants”).
These
Common Shares, Private Warrants and the Common Shares issuable upon exercise of the Private Warrants are being offered pursuant to the
exemption provided in Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities Act”), and/or Rule 506(b)
promulgated thereunder and are not being registered under the Securities Act at this time or offered pursuant to this prospectus supplement
and the accompanying prospectus. See “Concurrent Private Placement.”
Our Chief Executive
Officer, President and Executive Chairman, Mark Smith, and one of our directors, Dean Kehler, have indicated an interest in purchasing
an aggregate of approximately $350,000 of our Common Shares and associated Private Warrants in the Concurrent Private Placement. However,
Mr. Smith and Mr. Kehler are not obligated to purchase any Common Shares and associated Private Warrants and may determine to purchase
fewer or more Common Shares and associated Private Warrants than they indicated an interest in purchasing or none at all.
|
Common Shares Outstanding Prior to this Offering (1) |
38,720,244 Common Shares. |
Common Shares Outstanding After this Offering(1) |
40,312,600 Common Shares (40,551,453 Common Shares if the underwriter exercises its over-allotment option to purchase Option Shares in full). |
No Fractional Warrants |
Computershare Inc. and its affiliate Computershare Trust Company, N.A., together as warrant agent, will not be required to effect any transaction that would result in the issuance of a fraction of a Public Warrant. If any fractional Public Warrant would otherwise be required to be issued or distributed, we will round down the total number of Public Warrants to be issued to the relevant holders
to the nearest whole number. As a result, holders should purchase only an even number of Common Shares in this offering or will otherwise have the amount of associated Series B Public Warrants rounded down. |
Use of Proceeds |
We
estimate that the net proceeds from the sale of the Common Shares and the Public Warrants
that we are offering, after deducting underwriting discounts and commissions (assuming no
sales to persons on the President’s List or to any of our directors and officers) and
estimated offering expenses but before giving effect to the exercise of any Public Warrants,
will be approximately $1,385,000 ($1,760,000 if
the underwriter exercises its over-allotment option to purchase Option Shares and Option
Warrants in full).
Upon
exercise, we will receive the cash exercise price of the Public Warrants offered hereby (assuming that they are not exercised on a cashless
basis). We believe the likelihood that holders of the Public Warrants will exercise their Public Warrants, and therefore the amount of
cash proceeds that we would receive, is, among other things, dependent upon the market price of our Common Shares. For so long as the
market price for our Common Shares is less than the exercise price of the Public Warrants, we believe such holders will be unlikely to
exercise their Public Warrants.
We expect to use
the net proceeds from this offering for working capital and general corporate purposes, including to (i) advance our efforts to launch
construction of the Elk Creek Project and move it to commercial operation and (ii) repay all amounts outstanding under the Smith Loan
(as defined herein). See “Use of Proceeds.”
|
Dividend Policy |
We have not paid dividends
on our Common Shares and do not intend to pay dividends in the foreseeable future. |
Trading Market |
Our
Common Shares trade on the Nasdaq Global Market under the symbol “NB.”
There is no established trading market for the Public Warrants and we do
not expect a market to develop. In addition, we do not intend to list the Public Warrants on any national securities exchange or any other
nationally recognized trading system. |
Risk Factors |

Risk
Factors
Investing in our Common Shares involves a
high degree of risk. Before making a decision to invest in our Common Shares, you should carefully consider the risks described below
and under the heading “Risk Factors” in the accompanying prospectus, and discussed under Part I, Item 1A. “Risk Factors”
contained in our most recent Annual Report on Form 10-K, which is incorporated by reference into this prospectus supplement and the accompanying
prospectus in their entirety, together with other information in this prospectus supplement and the accompanying prospectus and the documents
incorporated by reference herein and therein. See the sections of this prospectus supplement entitled “Where You Can Find More Information”
and “Incorporation of Documents by Reference.” Additional risks and uncertainties not presently known to us or that we currently
deem immaterial may also affect our business, financial condition or results of operations. The occurrence of any of these known or unknown
risks might cause you to lose all or part of your investment in our Common Shares.
Risks Related to this Offering
Our Common Share price may be volatile and as a result you
could lose all or part of your investment.
In addition to volatility
associated with equity securities in general, the value of your investment could decline due to the impact of any of the following factors
upon the market price of the Common Shares:
| ● | disappointing results from our exploration and/or, if warranted, project development efforts; |
| ● | decline in demand for Common Shares; |
| ● | downward revisions in securities analysts’ estimates or changes in general market conditions; |
| ● | technological innovations by competitors or in competing technologies; |
| ● | investor perception of our industry or our prospects; and |
| ● | general economic trends. |
In the past fiscal year,
the trading price of our stock on the Nasdaq Global Market has ranged from a low of $1.65 to a high of $5.36.
In addition, stock markets
in general have experienced extreme price and volume fluctuations, and the market prices of securities have been highly volatile. These
fluctuations are often unrelated to operating performance and may adversely affect the market price of the Common Shares. As a result,
you may be unable to sell any Common Shares you acquire at a desired price.
Sales of Common Shares in this offering could adversely affect
prevailing market prices for the Common Shares, and you may experience immediate and substantial dilution.
If all of the Common Shares offered by this prospectus supplement were issued
and outstanding, they would represent a substantial percentage of our public float and of our outstanding Common Shares. As of the date
of this prospectus supplement, the Common Shares offered by this prospectus supplement would represent approximately 4.5%
of the total number of outstanding Common Shares (assuming the underwriter exercises its over-allotment option to purchase Option Shares
in full and not including: Common Shares issuable upon exercise of the Public Warrants offered hereby; Common Shares to be issued to the Private Investors in the Concurrent Private Placement; Common Shares issuable upon exercise of the Private Warrants to be issued to the Private Investors in the Concurrent Private Placement; Common Shares issuable upon exercise of outstanding
stock options, or reserved for future issuance, under the LTIP; Common Shares issuable in respect of the commitment amount pursuant to
the Yorkville Equity Facility Financing Agreement; and Common Shares issuable upon conversion, exercise or exchange of other outstanding
securities, as described herein). In addition, if all of the Public Warrants offered by this prospectus supplement are exercised, the
Common Shares offered by this prospectus supplement would represent an even higher percentage of the total number of outstanding Common
Shares. Accordingly, the sale of the Common Shares offered by this prospectus supplement, or the perception that such sales may occur,
could result in a significant decline in the public trading price of our Common Shares.
In addition, because the price per share of
our Common Shares being offered by this prospectus supplement may be higher than the book value per share of our Common Shares, investors
in this offering may suffer immediate and substantial dilution in the net tangible book value of the Common Shares purchased in this offering.
If all of the Public Warrants offered by this prospectus supplement are exercised, further dilution in the net tangible book value of the
Common Shares purchased in this offering could occur. See the section
entitled “Dilution” below for a more detailed discussion of the dilution investors may incur in this offering.
Future sales, or the perception of
future sales, of Common Shares by existing shareholders or by us, or future dilutive issuances of Common Shares by us, could adversely
affect prevailing market prices for the Common Shares and cause investors to suffer dilution in their net book value per Common Share.
In the Concurrent Private Placement, we expect to sell an aggregate of 2,199,888 Common Shares, associated Series A Private Warrants to purchase up to an aggregate of 2,199,888 Common Shares, and associated Series B Private Warrants to purchase up to an aggregate of 1,099,944 Common Shares. In addition, sales of a substantial
number of Common Shares in the public market could occur at any time, including issuances and sales of additional Common Shares by us
and sales by other security holders. These sales, or the market perception that the holders of a large number of Common Shares or securities
convertible, exercisable, or exchangeable into Common Shares intend to sell Common Shares, could reduce the prevailing market price of
the Common Shares. The effect, if any, that future public sales of these securities or the availability of these securities for sale will
have on the market price of the Common Shares is uncertain. If the market price of the Common Shares were to drop as a result, this might
impede our ability to raise additional capital and might cause remaining shareholders to lose all or part of their investment.
The Articles of NioCorp,
as amended in connection with the 2023 Transactions (as defined below), permit us to issue an unlimited number of Common Shares. Subject
to the requirements of the Business Corporations Act (British Columbia) and The Nasdaq Stock Market LLC (“Nasdaq”), we will
not be required to obtain the approval of the NioCorp shareholders for the issuance of additional Common Shares. We have issued Common
Shares in the past and will continue to issue Common Shares to finance our activities in the future. In addition, outstanding options,
warrants to purchase Common Shares, and securities convertible into or exchangeable for Common Shares may be exercised, converted or exchanged,
resulting in the issuance of additional Common Shares, including, without limitation, an aggregate of 17,519,864 Common Shares issuable
upon exercise of NioCorp Assumed Warrants an aggregate of 5,266,359 Common Shares issuable upon exercise of other outstanding warrants,
an aggregate of 7,673,712 Common Shares issuable under certain conditions upon exchange of shares of Class B common stock of ECRC and
Common Shares issuable upon conversion of the April 2024 Notes. If we issue additional Common Shares or decide to enter into joint ventures
with other parties in order to raise financing through the sale of equity securities, investors’ interests in the Company will be
diluted and investors may suffer dilution in their net book value per Common Share depending on the price at which such securities are
sold.
Additionally, pursuant
to the Yorkville Equity Facility Financing Agreement, Yorkville has committed to purchase up to an additional $58.7 million of our Common
Shares, at our direction from time to time during the remainder of the commitment period, subject to certain limitations
and the satisfaction of the conditions in the Yorkville Equity Facility Financing Agreement. We have filed a registration statement under
the Securities Act covering resales by Yorkville of the Common Shares issuable pursuant to the Yorkville Equity Facility Financing Agreement.
Accordingly, any Common Shares that we issue pursuant to the Yorkville Equity Facility Financing Agreement will be available for sale
into the public market, subject to applicable securities laws, which could reduce the prevailing market price for the Common Shares.
Our management will have broad discretion over the use of the proceeds
we receive in this offering and might not apply the proceeds in ways that increase the value of your investment.
Our management will have broad discretion to use the
net proceeds from this offering, and we may not apply the net proceeds of this offering in ways that increase the value of your investment.
Pending their use, we intend to invest the net proceeds from this offering in marketable securities that may include investment-grade
interest-bearing securities, money market accounts, certificates of deposit, commercial paper and guaranteed obligations of the U.S. government.
These investments may not yield a favorable return to our shareholders. If we do not invest or apply the net proceeds from this offering
in ways that enhance shareholder value, we may fail to achieve expected financial results, which could cause our share price to decline.
We are subject to the continued listing
criteria of the Nasdaq and our failure to satisfy these criteria may result in delisting of the Common Shares.
Our Common Shares are currently
listed on the Nasdaq Global Market under the symbol “NB”. The public NioCorp Assumed Warrants are currently listed on the
Nasdaq Capital Market under the symbol “NIOBW.” Nasdaq
has rules for continued listing. In order to
maintain the listings, we must maintain certain financial and share distribution targets, including maintaining a minimum number of public
shareholders.
If Nasdaq delists the Common
Shares, investors may face material adverse consequences, including, but not limited to, a lack of a trading market for the Common Shares,
reduced liquidity, a determination that our Common Shares are a “penny stock,” decreased analyst coverage of the Company,
and an inability for us to obtain additional financing to fund our operations.
NioCorp may be a “passive foreign investment company”
for the current taxable year and for one or more future taxable years, which may result in materially adverse U.S. federal income tax
consequences for U.S. investors.
If NioCorp is a passive foreign investment company (“PFIC”) for
any taxable year, or portion thereof, that is included in the holding period of a U.S. Holder (as defined in “Certain United
States Federal Income Tax Considerations,” below) of Common Shares or Public Warrants, such U.S. Holder may be subject to certain
adverse U.S. federal income tax consequences and additional reporting requirements. NioCorp believes that it was classified as a PFIC
for its taxable years ended June 30, 2024 and June 30, 2023 and, based on the current composition of its income and assets, as well as
current business plans and financial expectations, may be classified as a PFIC for its current and future taxable years. Any conclusion
regarding PFIC status is a factual determination that must be made annually at the close of each taxable year and, thus, is subject to
change. In addition, even if NioCorp concluded it did not qualify as a PFIC, it is possible that the U.S. Internal Revenue Service (the
“IRS”) could assert, and that a court could sustain, a determination that NioCorp is a PFIC. Accordingly, there can be no
assurance that NioCorp will not be treated as a PFIC for any taxable year. Each holder of Common Shares or Public Warrants should consult
its own tax advisors regarding the PFIC rules and the U.S. federal income tax consequences of the acquisition, ownership, and disposition
of such securities. See “Certain United States Federal Income Tax Considerations” below, for further details regarding
this issue.
The 2023 Transactions could result in NioCorp becoming subject
to materially adverse U.S. federal income tax consequences.
Section 7874 and related
sections of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), provide for certain adverse tax consequences
when the stock of a U.S. corporation is acquired by a non-U.S. corporation in certain transactions in which former shareholders of the
U.S. corporation come to own 60% or more of the stock of the non-U.S. corporation (by vote or value, and applying certain specific counting
and ownership rules). These adverse tax consequences include (i) potential additional required gain recognition by the U.S. corporation,
(ii) treatment of certain payments to the non-U.S. corporation that reduce gross income as “base erosion payments,” (iii)
an excise tax on certain options and stock-based compensation of the U.S. corporation, (iv) disallowance of “qualified dividend”
treatment for distributions by the non-U.S. corporation, and (v) if former shareholders of the U.S. corporation come to own 80% or more
of the stock of the non-U.S. corporation, treatment of the non-U.S. corporation as a U.S. corporation subject to U.S. federal income tax
on its worldwide income (in addition to any tax imposed by non-U.S. jurisdictions). If the transactions contemplated by the Business Combination
Agreement (as defined herein) that closed in March 2023, including, among others, the GXII Transaction (as defined herein) and the Yorkville
Equity Facility Financing Agreement (the “2023 Transactions”) result in the application of any of these, or any other, adverse
tax consequences, NioCorp could incur significant additional tax costs. While NioCorp currently does not believe the 2023 Transactions
will cause such adverse tax consequences as a result of Section 7874 and related sections of the Code, this determination is subject to
significant legal and factual uncertainty. NioCorp has not sought and will not seek any rulings from the IRS as to the tax treatment of
any of the 2023 Transactions. Further, there can be no assurance that your tax advisor, the IRS, or a court, will agree with the position
that NioCorp is not subject to these adverse tax consequences.
If our Common Shares are considered a
penny stock and are subject to the penny stock rules, broker-dealers may be discouraged from effecting transactions in Common Shares.
Our Common Shares have
in the past, and may in the future, be considered a “penny stock.” The SEC has adopted Rule 15g-9 which generally defines
“penny stock” to be any equity security that has a market price (as defined) less than $5.00 per share or an exercise price
of less than $5.00 per share, subject to certain exceptions. Applicable penny stock rules impose additional sales practice requirements
on broker-dealers who sell to persons other than established customers and “accredited investors.” The term “accredited
investor” refers generally to
institutions with assets in excess of $5.0
million or individuals with a net worth in excess of $1.0 million or annual income exceeding $200,000 or $300,000, jointly with their
spouse. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to
deliver a standardized risk disclosure document in a form prepared by the SEC, which provides information about penny stocks and the nature
and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for
the penny stock, the compensation of the broker-dealer and its salesperson in the transaction, and monthly account statements showing
the market value of each penny stock held in the customer’s account. The bid and offer quotations, and the broker-dealer and salesperson
compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the
customer in writing before or with the customer’s confirmation. In addition, the penny stock rules require that prior to a transaction
in a penny stock not otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock
is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. If and when applicable,
these disclosure requirements may have the effect of reducing the level of trading activity in the secondary market for the Common Shares.
Consequently, these penny stock rules may affect the ability of broker-dealers to trade in the Common Shares.
There is currently no public market for the Public Warrants offered hereby and
there is no guarantee that the Public Warrants will be listed on any stock exchange.
There is currently no public market for the Public Warrants offered hereby and
there can be no assurance that an active public market will develop or be sustained after completion of the offering. We do not intend
to list the Public Warrants for trading on any securities exchange. In the event a public market for the Public Warrants does not develop
or cannot be sustained, it is not possible to predict the price at which the Public Warrants will trade in the secondary market or whether
such market will be liquid or illiquid. To the extent the Public Warrants are exercised, the number of Public Warrants outstanding will
decrease, resulting in diminished liquidity for such remaining outstanding Public Warrants. A decrease in the liquidity of the Public
Warrants may cause, in turn, an increase in the volatility associated with the price of the Public Warrants. To the extent that the Public
Warrants are or become illiquid, an investor may have to exercise the Public Warrants to realize value.
Investors will have no rights as a shareholder with respect to their Public Warrants
until they exercise their Public Warrants and acquire our Common Shares.
Until you acquire Common Shares upon exercise of your Public Warrants, you will
have no rights with respect to the Common Shares underlying such Public Warrants. Upon exercise of your Public Warrants, you will be entitled
to exercise the rights of a shareholder only as to matters for which the record date occurs after the exercise date.
We have never paid dividends on the Common Shares.
We have not paid dividends on the Common Shares to
date, and we may not be in a position to pay dividends for the foreseeable future. Our ability to pay dividends with respect to the Common
Shares will depend on our ability to successfully develop one or more properties and generate earnings from operations. Further, our initial
earnings, if any, will likely be retained to finance our operations. Any future dividends on Common Shares will depend upon our earnings,
our then-existing financial requirements, and other factors, and will be at the discretion of our Board.

and similar expressions, or statements that events, conditions, or results “will,” “may,” “could,”
or “should” (or the negative and grammatical variations of any of these terms) occur or be achieved. Any statements that express
or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions, or future events
or performance (often, but not always, using words or phrases such as “expects” or “does not expect,” “is

and assumptions. Many factors could cause actual results, performance, or achievements to be materially different from any future results,
performance, or achievements that may be expressed or implied by such forward-looking statements, including, among others, risks related
to the following: our ability to consummate this offering; our ability to use the net proceeds of this offering in a manner that will
increase the value of shareholders’ investment; our ability to consummate the Concurrent Private Placement; our ability to use the
net proceeds of the Concurrent Private Placement in a manner that will increase the value of shareholders’ investment; our ability
to operate as a going concern; our requirement of significant additional capital; our ability to receive sufficient project financing

including our ability to access the full amount of the expected net proceeds under the Yorkville Equity Facility Financing Agreement;
our ability to continue to meet Nasdaq listing standards; risks relating to the Common Shares, including price
volatility, lack of dividend payments
and dilution or the perception of the likelihood of any of the foregoing; the extent to which our level of indebtedness and/or the terms
contained in agreements governing our indebtedness or the Yorkville Equity Facility Financing Agreement may impair our ability to obtain
additional financing; covenants contained in agreements with our secured creditors that may affect our assets; our limited operating history;
our history of losses; the material weaknesses in our internal control over financial reporting, our efforts to remediate such material
weaknesses and the timing of remediation; the possibility that we may qualify as a PFIC under the Code; the potential that the 2023 Transactions
could result in us becoming subject to materially adverse U.S. federal income tax consequences as a result of the application of Section
7874 and related sections of the Code; cost increases for our exploration and, if warranted, development projects; a disruption in, or
failure of, our information technology systems, including those related to cybersecurity; equipment and supply shortages; variations in
the market demand for, and prices of, niobium, scandium, titanium and rare earth products; current and future offtake agreements, joint
ventures, and partnerships; our ability to attract qualified management; estimates of mineral resources and reserves; mineral exploration
and production activities; feasibility study results; the results of metallurgical testing; the results of technological research; changes
in demand for and price of commodities (such as fuel and electricity) and currencies; competition in the mining industry; changes or disruptions
in the securities markets; legislative, political or economic developments, including changes in federal and/or state laws that may significantly
affect the mining industry; the impacts of climate change, as well as actions taken or required by governments related to strengthening
resilience in the face of potential impacts from climate change; the need to obtain permits and comply with laws and regulations and other
regulatory requirements; the timing and reliability of sampling and assay data; the possibility that actual results of work may differ
from projections/expectations or may not realize the perceived potential of our projects; risks of accidents, equipment breakdowns, and
labor disputes or other unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in development
programs; operating or technical difficulties in connection with exploration, mining, or development activities; management of the water
balance at the Elk Creek Project site; land reclamation requirements related to the Elk Creek Project; the speculative nature of mineral
exploration and development, including the risks of diminishing quantities of grades of reserves and resources; claims on the title to
our properties; potential future litigation; and our lack of insurance covering all of our operations.
Should one or more of these risks or uncertainties
materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described herein. This list
is not exhaustive of the factors that may affect any of the Company’s forward-looking statements. Forward-looking statements are
statements about the future and are inherently uncertain, and actual achievements of the Company or other future events or conditions
may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties, and other factors,
including without limitation those discussed in this prospectus supplement and the accompanying prospectus under the heading “Risk
Factors” and under Part I, Item 1A. “Risk Factors” contained in our most recent Annual Report on Form 10-K, and
Part II, Item 1A. “Risk Factors” contained in our subsequent Quarterly Reports on Form 10-Q, as well as any amendments thereto,
which are incorporated by reference into this prospectus supplement and the accompanying prospectus in their entirety, together with other
information in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference herein and therein.

of Documents by Reference.”
The Company’s forward-looking statements
contained in this prospectus supplement are based on the beliefs, expectations, and opinions of management as of the date of this prospectus
supplement. The Company does not assume any obligation to update forward-looking statements if circumstances or management’s beliefs,
expectations, or opinions should change, except as required by law. For the reasons set forth above, investors should not attribute undue
certainty to, or place undue reliance on, forward-looking statements.
Use
of Proceeds
We estimate that the net proceeds from the sale of the Common Shares and the
Public Warrants offered hereby, after deducting underwriting discounts and commissions (assuming no sales to persons on the President’s
List or to any of our directors or officers) and estimated offering expenses payable by us but before giving effect to the exercise of
any Public Warrants, will be approximately $1,385,000 ($1,760,000 if
the underwriter exercises its over-allotment option to purchase Option Shares and Option Warrants in full). This does not take into consideration
any net proceeds that may be raised pursuant to the Concurrent Private Placement to the Private Investors.
Upon exercise, we will receive the cash exercise price of the Public Warrants
offered hereby (assuming that they are not exercised on a cashless basis). We believe the likelihood that holders of the Public Warrants
will exercise their Public Warrants, and therefore the amount of cash proceeds that we would receive, is, among other things, dependent
upon the market price of our Common Shares. For so long as the market price for our Common Shares is less than the exercise price of the
Public Warrants, we believe such holders will be unlikely to exercise their Public Warrants.
We expect to use the net proceeds from this offering for working capital and general corporate purposes, including to (i) advance our
efforts to launch construction of the Elk Creek Project and move it to commercial operation and (ii) repay all amounts outstanding under
the Company's $2.0 million non-revolving, multiple draw credit facility (the “Smith Loan”) available pursuant to the Loan Agreement, dated
September 11, 2024, by and between the Company and Mark Smith (the “Smith Loan Agreement”).
As of November 1, 2024, there was approximately $504,000 outstanding
under the Smith Loan. The Smith Loan has an interest rate of 10% per annum, calculated monthly in arrears, through the date of repayment
of the Smith Loan. The Company can pre-pay the Loan at any time without notice and without penalty, but any amount of principal or interest
repaid by the Company prior to the earlier of the date of expiration of the Smith Loan Agreement on June 30, 2025 and the occurrence of
an event of default under the Smith Loan Agreement will be subject to an early payment fee of 2.5% of the value of any such payment.
DILUTION
If you invest in our Common Shares and associated Public Warrants in this offering,
your interest will be diluted immediately to the extent of the difference between the combined offering price per Common Share and associated
Public Warrants and the adjusted net tangible book value per Common Share after this offering.
Our net tangible book value as of June 30, 2024,
was approximately $2.5 million, or $0.07 per Common Share, based upon the number of Common Shares outstanding as of that date. Net
tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of Common Shares
outstanding. Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of
Common Shares in this offering and the net tangible book value per Common Share immediately after this offering.
After giving effect to the sale by us of
1,592,356 Common Shares and associated Public Warrants being offered in this offering at a combined public offering price of
$1.57 per Common Share and associated Public Warrants and after deducting
underwriting discounts and commissions (assuming no sales to persons on the President’s List or to any person who is a
director or officer of the Company) and estimated offering expenses payable by us but before giving effect to the exercise of any
Public Warrants, our as-adjusted net tangible book value as of June 30, 2024 would have been approximately
$3,851,000, or $0.10 per
Common Share. This represents an immediate increase in the net tangible book value of
$0.03 per Common Share to our existing shareholders and an immediate and
substantial dilution in net tangible book value of $1.47 per Common Share to
new investors purchasing our Common Shares and associated Public Warrants in this offering. This does not take into consideration
the securities issuable in connection with the Concurrent Private Placement to the Private Investors.
The
following table illustrates this per Common Share dilution:

Net tangible book value per Common Share as of June 30, 2024 | |

Shares and associated Public Warrants in this offering | |
| | | |
$ | 1.47 | |
The above discussion and table are based on
38,062,647 Common Shares outstanding as of June 30, 2024 and excludes the following securities:
| ● | Common Shares issuable upon exercise of any Public Warrants offered hereby; |
| ● | Common Shares issuable upon exercise of outstanding stock options under the LTIP; |
| ● | Common Shares reserved for future issuance under the LTIP; |
| ● | Common Shares issuable in respect of the commitment amount under the Yorkville Equity Facility Financing Agreement; |
| ● | an aggregate of 7,673,712 Common Shares issuable under certain conditions upon exchange of shares of Class B common stock of ECRC; |
| ● | an aggregate of 17,519,864 Common Shares issuable upon exercise of NioCorp Assumed Warrants; |
| ● | an aggregate of 5,266,359 Common Shares issuable upon exercise of other outstanding
Common Share purchase warrants with a weighted-average exercise price of approximately $3.38; |
| ● | Common Shares issuable upon conversion of the April 2024 Notes; |
|
● |
Common Shares to be issued
to the Private Investors in the Concurrent Private Placement; and |
|
● |
Common Shares issuable upon
exercise of the Private Warrants to be issued to the Private Investors in the Concurrent Private Placement. |
Description
of SECURITIES
Common Shares
The authorized capital of the Company consists
of an unlimited number of Common Shares, without par value. The holders of Common Shares are entitled to receive notice of and attend
all meetings of shareholders, with each Common Share held entitling the holder to one (1) vote on any resolution to be passed at such
shareholder meetings. The holders of Common Shares are entitled to dividends if, as and when declared by the Company’s Board of
Directors. The Common Shares are entitled, upon liquidation, dissolution, or winding up of the Company, to receive the remaining assets
of the Company available for distribution to shareholders. There are no pre-emptive, conversion, or redemption rights attached to the
Common Shares.
Exchange Controls
There are no governmental laws, decrees, or
regulations in Canada that restrict the export or import of capital, including foreign exchange controls, or that affect the remittance
of dividends, interest or other payments to non-resident holders of the securities of the Company, other than as discussed below and Canadian
withholding tax. See “Certain Canadian Federal Income Tax Considerations for U.S. Residents” below.
Competition Act
Limitations on the ability to acquire and hold
Common Shares may be imposed by the Competition Act (Canada). This legislation permits the Commissioner of Competition of Canada (the
“Commissioner”) to review any acquisition of a significant interest in the Company. This legislation grants the Commissioner
jurisdiction to challenge such an acquisition before the Canadian Competition Tribunal if the Commissioner believes that it would, or
would be likely to, result in a substantial lessening or prevention of competition in any market in Canada.
Investment Canada Act
The Investment Canada Act subjects an acquisition
of control of a Canadian business by a non-Canadian to government notification or review depending on whether the relevant financial threshold
(based on enterprise value or asset value of the company), as calculated pursuant to the legislation, exceeds a threshold amount. A reviewable
acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to result in a net benefit to Canada.
Under the national-security-review regime in the Investment Canada Act, review on a discretionary basis may also be undertaken by the
federal government in respect of a broad range of investments by a non-Canadian. No financial threshold applies to a national security
review. The relevant test is whether such investment by a non-Canadian could be “injurious to national security.”
Warrants
From time to time, the Company has outstanding
Common Share purchase warrants, with each Common Share purchase warrant exercisable for one Common Share. The exercise price per Common
Share and the number of Common Shares issuable upon exercise of Common Share purchase warrants is subject to adjustment upon the occurrence
of certain events, including, but not limited to, the following:
| ● | the subdivision or re-division of the outstanding Common Shares into a greater number of Common Shares; |
| ● | the reduction, combination or consolidation of the outstanding Common Shares into a lesser number of Common Shares; |
| ● | the issuance of Common Shares or securities exchangeable for, or convertible into, Common Shares to all or substantially all of the
holders of Common Shares by way of stock dividend or other distribution (other than a distribution of Common Shares upon the exercise
of Common Share purchase warrants or any outstanding options); |
| ● | the reorganization of the Company or the consolidation or merger or amalgamation of the Company with or into another corporate body;
and |
| ● | a reclassification or other similar change to the outstanding Common Shares. |
The Company will issue the Common Shares issuable
upon exercise of Common Share purchase warrants within five business days following its receipt of notice of exercise and payment of the
exercise price, subject to surrender of the Common Share purchase warrants. Prior to the exercise of any Common Share purchase warrants,
holders of the Common Share purchase warrants will not have any of the rights of holders of the Common Shares issuable upon exercise,
including the right to vote or to receive any payments of dividends on the Common Shares issuable upon exercise.
NioCorp Assumed Warrants
On March 17, 2023 (the “Closing Date”),
the Company closed a series of transactions (the “GXII Transaction”) pursuant to the Business Combination Agreement, dated
as of September 25, 2022 (the “Business Combination Agreement”), by and among the Company, GX Acquisition Corp. II, a Delaware
corporation (“GXII”), and Big Red Merger Sub Ltd., a Delaware corporation and a direct, wholly owned subsidiary of the Company.
In connection with the closing of the GXII Transaction (the “Closing”), pursuant to the Business Combination Agreement, the
Company assumed GXII’s obligations under the Warrant Agreement, dated as of March 17, 2021 (the “GXII Warrant Agreement”),
by and between GXII and Continental Stock Transfer & Trust Company (“CST”), as warrant agent, and each share purchase
warrant of GXII thereunder (the “GXII Warrants”) that was issued and outstanding immediately prior to the Closing Date was
converted into one Common Share purchase warrant (the “NioCorp Assumed Warrants”) pursuant to the GXII Warrant Agreement,
as amended by an Assignment, Assumption and Amendment Agreement, dated the Closing Date (the GXII Warrant Agreement, as so amended, the
“NioCorp Assumed Warrant Agreement”), among the Company, GXII, CST, as existing warrant agent, and Computershare Inc. and
its affiliate Computershare Trust Company, N.A, together as successor warrant agent (the “NioCorp Assumed Warrant Agent”).
In connection with the Closing, NioCorp issued (a) 9,999,959 public NioCorp Assumed Warrants in respect of the GXII Warrants that were
publicly traded prior to the Closing and (b) 5,666,667 NioCorp Assumed Warrants to GX Sponsor II LLC (the “Sponsor”) in respect
of the GXII Warrants that it held prior to the Closing, which NioCorp Assumed Warrants were subsequently distributed by the Sponsor to
its members in connection with the Closing.
Both the public NioCorp Assumed Warrants and the NioCorp
Assumed Warrants issued to the Sponsor are subject to the terms of the NioCorp Assumed Warrant Agreement and are identical, with certain
exceptions applicable to the NioCorp Assumed Warrants issued to the Sponsor for so long as such NioCorp Assumed Warrants are held by the
Sponsor, its members, or their respective affiliates and other permitted transferees. In accordance with the NioCorp Assumed Warrant Agreement,
any NioCorp Assumed Warrants issued to the Sponsor that are held by someone other than the Sponsor, its members, or their respective affiliates
and other permitted transferees, are treated as public NioCorp Assumed Warrants.
Each NioCorp Assumed Warrant is exercisable on and
after April 16, 2023 until its expiration for 1.11829212 Common Shares at a price of $11.50 per 1.11829212 Common Shares (subject to adjustments
for stock splits, stock dividends, reorganizations, recapitalizations and the like). Under the terms of NioCorp Assumed Warrant Agreement,
for so long as the NioCorp Assumed Warrants issued to the Sponsor are held by the Sponsor, its members, or their respective affiliates
and other permitted transferees, such holders have the right to elect to exercise those NioCorp Assumed Warrants on a cashless basis.
For such NioCorp Assumed Warrants exercised on a cashless basis after the Closing, the holder will be entitled to pay the exercise price
for those NioCorp Assumed Warrants by surrendering all or portion of the cash and/or Common Shares (valued at their fair market value)
into which those NioCorp Assumed Warrants are exercisable as shall be elected by the holder. For this purpose, Common Shares so surrendered
will be deemed to have a “fair market value” equal to the average reported last sale price of the Common Shares for the 10
trading days ending on the third trading day prior to the date of exercise of the applicable NioCorp Assumed Warrants.
The NioCorp Assumed Warrants will expire at 5:00 p.m.,
New York City time, on March 17, 2028 or earlier upon redemption or liquidation.
The Company will not be obligated to deliver any Common
Shares pursuant to the exercise of a NioCorp Assumed Warrant and will have no obligation to settle such exercise unless a registration
statement under the Securities Act with respect to the Common Shares underlying the NioCorp Assumed Warrants is then effective and a prospectus
relating thereto is current, subject to the Company satisfying its obligations described below with respect to registration. No NioCorp
Assumed Warrant will be exercisable and the Company will not be obligated to issue Common Shares upon exercise of a NioCorp Assumed Warrant
unless Common Shares issuable upon such exercise have been registered, qualified or deemed to be exempt under the securities laws of the
state of residence of the registered holder of the NioCorp Assumed Warrants. In the event that the conditions in the two immediately preceding
sentences are not satisfied with respect to a NioCorp Assumed Warrant, the holder of such NioCorp Assumed Warrant will not be entitled
to exercise such NioCorp Assumed Warrant and such NioCorp Assumed Warrant may have no value and expire worthless. In no event will the
Company be required to net cash settle any NioCorp Assumed Warrant.
The NioCorp Assumed Warrants, and the underlying Common
Shares issuable upon the exercise thereof, were registered under the Securities Act pursuant to the Company’s registration statement
on Form S-4, originally filed on November 7, 2022, as subsequently amended, which was declared effective by the SEC on February 8, 2023.
The ongoing registered offering of the Common Shares underlying the NioCorp Assumed Warrants is being conducted pursuant to the Company’s
registration statement on Form S-3, originally filed on April 14, 2023, as subsequently post-effectively amended to convert such registration
statement to Form S-1, which was declared effective on October 30, 2023.
The Company will have the right to call the public
NioCorp Assumed Warrants for redemption at any time following the Closing Date:
| ● | in whole and not in part; |
| ● | at a price of $0.01 per NioCorp Assumed Warrant; |
| ● | upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each public NioCorp
Assumed Warrant holder; |
| ● | if, and only if, the reported last sale price of the Common Shares equals or exceeds approximately $16.10 per share (subject to certain
adjustments) for any 20 trading days within a 30-trading day period commencing once the NioCorp Assumed Warrants become exercisable and
ending three business days before the Company sends the notice of redemption to the public NioCorp Assumed Warrant holders; and |
| ● | if there is an effective registration statement covering the Common Shares issuable upon exercise of the NioCorp Assumed Warrants,

The NioCorp Assumed Warrants issued to the Sponsor
are not redeemable by the Company for so long as such NioCorp Assumed Warrants are held by the Sponsor, its members, or their respective
affiliates or other permitted transferees. In addition, the Company may not exercise its redemption right if the issuance of Common Shares
upon exercise of the NioCorp Assumed Warrants is not exempt from registration or qualification under applicable state blue sky laws or
the Company is unable to effect such registration or qualification.
If the Company calls the public NioCorp Assumed Warrants
for redemption as described above, the Company will have the option to require any holder that wishes to exercise its public NioCorp Assumed
Warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their public NioCorp Assumed
Warrants on a “cashless basis,” the Company will consider, among other factors, its cash position, the number of NioCorp Assumed
Warrants that are outstanding and the dilutive effect on the Company’s shareholders of issuing the maximum number of Common Shares
issuable upon the exercise of the NioCorp Assumed Warrants. If the Company takes advantage of this option, all holders of public NioCorp
Assumed Warrants would pay the exercise price by surrendering their NioCorp Assumed Warrants for that number of Common Shares equal to
the quotient
obtained by dividing (x) the product of the number of Common Shares underlying
the public NioCorp Assumed Warrants, multiplied by the difference between the exercise price of the NioCorp Assumed Warrants and the “fair
market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported
last sale price of the Common Shares for the 10 trading days ending on the third trading day prior to the date on which the notice of
redemption is sent to the holders of public NioCorp Assumed Warrants. If the Company takes advantage of this option, the notice of redemption
will contain the information necessary to calculate the number of Common Shares to be received upon exercise of the NioCorp Assumed Warrants,
including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of Common
Shares to be issued and thereby lessen the dilutive effect of a redemption of the public NioCorp Assumed Warrants. If the Company calls
the public NioCorp Assumed Warrants for redemption and does not take advantage of this option, the Sponsor, its members, and their respective
affiliates and other permitted transferees would still be entitled to exercise their NioCorp Assumed Warrants for cash or on a cashless
basis using the same formula described above that other NioCorp Assumed Warrant holders would have been required to use had all NioCorp
Assumed Warrant holders been required to exercise their NioCorp Assumed Warrants on a cashless basis, as described in more detail below.
A holder of a NioCorp Assumed Warrant may notify the
Company in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such NioCorp
Assumed Warrant, to the extent that after giving effect to such exercise, such holder (together with such holder’s affiliates),
to the NioCorp Assumed Warrant Agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount
as a holder may specify) of the Common Shares outstanding immediately after giving effect to such exercise.
The NioCorp Assumed Warrants have certain anti-dilution
and adjustments rights upon certain events.
The NioCorp Assumed Warrants may be exercised upon
surrender of the certificate representing such NioCorp Assumed Warrants on or prior to the expiration date at the offices of the NioCorp
Assumed Warrant Agent, with the exercise form on the reverse side of such certificate completed and executed as indicated, accompanied
by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to the order
of the NioCorp Assumed Warrant Agent or by wire transfer, for the number of NioCorp Assumed Warrants being exercised. The NioCorp Assumed
Warrant holders will not have the rights or privileges of holders of Common Shares or any attendant voting rights until they exercise
their NioCorp Assumed Warrants and receive Common Shares. After the issuance of Common Shares upon exercise of the NioCorp Assumed Warrants,
each holder will be entitled to one (1) vote for each Common Share held of record on all matters to be voted on by NioCorp shareholders.
If, upon exercise of the NioCorp Assumed Warrants,
a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round down to the nearest whole
number of Common Shares to be issued to the NioCorp Assumed Warrant holder.
The NioCorp Assumed Warrants were issued in registered
form under the NioCorp Assumed Warrant Agreement. The NioCorp Assumed Warrant Agreement may be amended by the parties thereto without
the consent of any registered holder (i) for the purpose of curing any ambiguity, or curing, correcting or supplementing any mistake,
or adding or changing any other provisions with respect to matters or questions arising under NioCorp Assumed Warrant Agreement as the
parties may deem necessary or desirable and that the parties deem shall not adversely affect the interest of the registered holders of
the NioCorp Assumed Warrants, and (ii) to provide for the delivery of such kind and amount of Common Shares or other securities or property
(including cash) receivable upon a reclassification, reorganization, merger or consolidation, or upon a dissolution following any such
sale or transfer, that the holder of NioCorp Assumed Warrants would have received if such holder had exercised his, her or its NioCorp
Assumed Warrants immediately prior to such event. All other modifications or amendments, including any amendment to increase the warrant
price or shorten the exercise period, shall require the vote or written consent of the registered holders of a majority of the then outstanding
public NioCorp Assumed Warrants. Any amendment solely to the NioCorp Assumed Warrants issued to the Sponsor and that are held by the Sponsor,
its members, or their respective affiliates or other permitted transferees, shall require the vote or written consent of a majority of
the holders of the then outstanding NioCorp Assumed Warrants issued to the Sponsor.
Notes
On April 12, 2024, the Company issued and sold to Yorkville
and Lind Global Fund II LP (“Lind II”), in a private placement, $8.0 million aggregate principal amount of unsecured notes
(the “April 2024 Notes”), pursuant to a Securities Purchase Agreement, dated April 11, 2024 (the “Purchase Agreement”),
between the Company and each of Yorkville and Lind II, as purchasers (in such capacity, the “Purchasers”). Pursuant to the
terms of the April 2024 Notes, subject to certain exceptions as described below, on the first day of each calendar month, beginning on
June 1, 2024 (excluding August 2024) (a “Payment Date”), the Company will be required to repay a portion of the outstanding
balance of all of the April 2024 Notes, on a pro-rata basis, in an amount equal to the sum of (i) $1.4 million of principal (or the outstanding
principal if less than such amount) in the aggregate among all of the outstanding April 2024 Notes, plus (ii) 8.0% of the principal amount
being paid (the “Payment Premium”), and (iii) accrued and unpaid interest, if any, as of the Payment Date. The Company is
required to make payments on each Payment Date until the entire outstanding principal is repaid, but will not have an obligation to make
a payment on a Payment Date if the Equity Conditions (as defined below) are satisfied.
Pursuant to the Purchase Agreement, the Purchasers
advanced an aggregate of $6.96 million to the Company in consideration of the issuance by the Company to the Purchasers of $8.0 million
aggregate principal amount of April 2024 Notes and Warrants (the “April 2024 Warrants”) to purchase up to 615,385 Common Shares
(the “April 2024 Warrant Shares”). Each April 2024 Warrant is exercisable for one Common Share for cash or, if at any time
there is no effective registration statement registering, or no current prospectus available for, the resale of the underlying Common
Shares, on a cashless basis at the option of the holder, at a price per Common Share of $3.25, subject to adjustment for recapitalizations,
stock splits, reverse stock splits or similar events, and expires April 12, 2027.
Subject to certain limitations, including those as
described below, contained within the April 2024 Notes, holders of the April 2024 Notes will be entitled to convert the principal amount
of, accrued and unpaid interest, if any, and any Payment Premium that has become due and payable on each Note, from time to time over
their term, into a number of Common Shares equal to the quotient of the amount being converted divided by the fixed conversion price of
$2.75 per Common Share (the “Fixed Conversion Price”) up to a maximum of 3,141,817 Common Shares (together with the April
2024 Warrant Shares, the “Underlying Shares”). The terms of the April 2024 Notes restrict the conversion of the April 2024
Notes by a holder if such a conversion or exercise would cause such holder to exceed certain beneficial ownership thresholds in the Company.
The April 2024 Notes are the unsecured obligations
of the Company and will mature on December 31, 2024. The April 2024 Notes will incur a simple interest rate obligation of 0.0% per annum
(which will increase to 18.0% per annum upon the occurrence of an event of default). The outstanding principal amount of, accrued and
unpaid interest, if any, on, and the Payment Premium, if any, on the April 2024 Notes must be paid by the Company in cash when the same
becomes due and payable under the terms of the April 2024 Notes at their stated maturity, upon their redemption or otherwise.
As mentioned above, the Company is required to make
payments on each Payment Date until the entire outstanding principal is repaid, but will not have an obligation to make a payment on a
Payment Date if the Equity Conditions are satisfied. The “Equity Conditions” means (i) on each of the five consecutive trading
days prior a Payment Date (the “Measuring Period”) a registration statement registering the resale by the Purchasers of the
Underlying Shares under the Securities Act (the “Underlying Shares Registration Statement”) is effective and available for
the resale by the Purchasers of all Underlying Shares, (ii) the Company has no knowledge of any fact that would cause the Underlying Shares
Registration Statement not to be effective and available for the resale of the Underlying Shares, (iii) on each day during the Measuring
Period, the Common Shares are designated for quotation on Nasdaq, or on such other market or exchange on which the Common Shares are then
listed or traded to the extent such other market or exchange is the principal U.S. trading market for the Common Shares (the “Principal
U.S. Market”), and have not been suspended from trading nor have delisting or suspension of trading been threatened or pending,
(iv) during the Measuring Period, an event of default has not occurred, (v) on each trading day during the Measuring Period, the daily
U.S. dollar volume-weighted average price for a Common Share on the Principal U.S. Market as reported by Bloomberg Financial Markets is
greater than 120% of the Fixed Conversion Price, (vi) on each trading day during the Measuring Period the average daily volume traded
exceeded $500,000, and (vii) there is no limitation on conversion under the terms of April 2024 Notes. In addition, any Payment Date and
the amount
payable to the holder of a Note on any such Payment Date may be modified
from time to time upon mutual written consent of the Company and such holder.
Pursuant to the terms of the April 2024 Notes, to the
extent a holder is a party to the Yorkville Equity Facility Financing Agreement, between the Company and Yorkville, under which Yorkville
agreed to purchase up to $65.0 million of Common Shares over a three-year period, at the Company’s discretion and subject to certain
restrictions (the “Yorkville Equity Facility Financing”), for so long as any amount remains outstanding under such holder’s
Note, the amount of cash received by the Company as payment from such holder in respect of an Advance (as defined in the Yorkville Equity
Facility Financing Agreement) is subject to a right of offset, exercisable in such holder’s sole discretion, against an equal amount
of principal, accrued and unpaid interest, if any, and other amounts that have become due and payable under the Note, not to exceed $1.512
million in any calendar month.
The April 2024 Notes may also be redeemed at the Company’s
option at any time and from time to time over their term at a redemption price equal to the principal amount being redeemed, plus the
Payment Premium, plus accrued and unpaid interest, if any, as of the redemption date.
The April 2024 Notes contain events of default customary
for instruments of their type (with customary grace periods, as applicable) and provide that, upon the occurrence of an event of default
arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding April 2024 Notes will become due
and payable immediately without further action or notice. If any other type of event of default occurs and is continuing, then any holder
may declare all of its April 2024 Notes to be due and payable immediately.
Pursuant to a global guaranty agreement, dated as of
April 11, 2024, among Elk Creek Resources Corp. (“ECRC”) and 0896800 B.C. Ltd. (together with ECRC, the “Guarantors”),
the Guarantors guaranteed the full, prompt and unconditional payment when due (whether at maturity, by acceleration or otherwise), and
the performance of all liabilities, agreements and other obligations of the Company to the Purchasers contained in the April 2024 Notes
and the Purchase Agreement, to the extent such liabilities, agreements and obligations are payable in cash.

of a cashless exercise). No fractional Common Shares will be issued in connection with the exercise of a Series A Public Warrant. If,
upon the exercise of a Series A Public Warrant, a holder would be entitled to receive a fractional interest in a Common Share, we will

beneficially own in excess of 4.99%, or 9.99% upon notice by the holder, of the number of our Common Shares outstanding immediately after
giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Series A Public Warrants.
However, any holder may increase or decrease such percentage to any other percentage upon at least 61 days’ prior notice from
the holder to us.
We

recognized trading system.
Subject

more of the outstanding Common Shares, a reclassification of our Common Shares, or the consummation by us of a stock or share purchase
agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger, amalgamation
or arrangement) with another person or group of persons whereby such other person or group acquires more than 50% of the outstanding
Common Shares, the holders of the Series A Public Warrants will be entitled to receive upon exercise of the Series A Public Warrants

Warrants immediately prior to such fundamental transaction. Additionally, as more fully described in the Series A Public Warrants, in
the event of certain fundamental transactions and subject to certain limitations set forth in the Series A Public Warrants, the holders
of the Series A Public Warrants will be entitled to receive consideration in an amount equal to the Black Scholes Value (as defined in

B Public Warrants
The
following is a brief summary of certain terms and conditions of the Series B Public Warrants being offered by this prospectus supplement.

issuable upon exercise of the Series B Public Warrants, the Series B Public Warrants may also be exercised, in whole or in part, by means
of a cashless exercise). No fractional Common Shares will be issued in connection with the exercise of a Series B Public Warrant. If,
upon the exercise of a Series B Public Warrant, a holder would be entitled to receive a fractional interest in a Common Share, we will
round down to the nearest whole number of Common Shares to be issued to the holder upon such exercise. Additionally, if any fractional
Series B Public Warrant would otherwise be required to be issued or distributed, the Company or the Warrant Agent, as applicable, will
round down the total number of Series B Public Warrants to be issued to the relevant holder to the nearest whole number.

CERTAIN
UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
The following is a general summary of certain U.S. federal income tax considerations
applicable to a U.S. Holder (as defined below) arising from and relating to (i) the acquisition, ownership, and disposition of Common
Shares, including Common Shares acquired upon exercise of a Public Warrant and (ii) the exercise, disposition, and lapse of Public Warrants.
This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S.
federal income tax considerations that may apply to a U.S. Holder of such securities. In addition, this summary does not take into account
the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such
U.S. Holder, including, without limitation, specific tax consequences to a U.S. Holder under an applicable income tax treaty. Accordingly,
this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder.
This summary does not address any tax consequences to U.S. Holders arising from the U.S. federal alternative minimum tax or the Medicare
tax on investment income, U.S. federal estate, gift and other non-income taxes, U.S. state and local taxes, or any non-U.S. tax. In addition,
except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each prospective U.S. Holder
should consult its own tax advisors regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal net investment income,
U.S. federal estate and gift, U.S. state and local, and non-U.S. tax considerations relevant to the Common Shares and Public Warrants.
No legal opinion from legal counsel or ruling from the IRS has been requested,
or will be obtained, regarding the U.S. federal income tax considerations relevant to the Common Shares and Public Warrants. This summary
is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions
taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the
IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.
Scope of this Summary
Authorities
This summary is based on the Code, Treasury
Regulations (whether final, temporary, or proposed), published rulings and administrative positions of the IRS, the Convention Between
Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-U.S.
Tax Convention”), and U.S. court decisions that are applicable, and, in each case, as in effect and available, as of the date of
this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and
any such change could be applied retroactively. This summary does not discuss the potential effects, whether adverse or beneficial, of
any proposed legislation.
U.S. Holders
For purposes of this summary, the term “U.S. Holder” means a beneficial
owner of Common Shares or Public Warrants that is for U.S. federal income tax purposes:
| ● | an individual who is a citizen or resident of the United States; |
| ● | a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) organized under the laws of the United
States, any state thereof or the District of Columbia; |
| ● | an estate whose income is subject to U.S. federal income taxation regardless of its source; or |
| ● | a trust that (1) is subject to the primary supervision of a court within the U.S. and the control of one or more U.S. persons for
all substantial decisions or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person. |
U.S. Holders Subject to Special U.S.
Federal Income Tax Rules Not Addressed
This summary does not address the U.S. federal income tax considerations applicable
to U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders that: (a) are tax-exempt
organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) are financial institutions,
underwriters, insurance companies, real estate investment trusts, regulated investment companies, or S corporations (or S corporation
shareholders); (c) are broker-dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting
method; (d) have a “functional currency” other than the U.S. dollar; (e) own Common Shares or Public Warrants as part of a
straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) acquire
Common Shares or Public Warrants in connection with the exercise of employee stock options or otherwise as compensation for services;
(g) hold Common Shares or Public Warrants other than as a capital asset within the meaning of Section 1221 of the Code (generally, property
held for investment purposes); (h) hold Common Shares or Public Warrants in connection with a trade or business, permanent establishment,
or fixed base outside the United States; or (i) own, have owned or will own (directly, indirectly, or by attribution) 10% or more of the
total combined voting power or value of the outstanding shares of the Company. This summary also does not address any tax considerations
applicable to U.S. Holders who are: (a) U.S. expatriates or former long-term residents of the U.S.; (b) persons that have been, are, or
will be a resident or deemed to be a resident in Canada for purposes of the Income Tax Act (Canada) and the regulations enacted thereunder
(the “Canadian Tax Act”); (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Common
Shares or Public Warrants in connection with carrying on a business in Canada; (d) persons whose Common Shares or Public Warrants constitute
“taxable Canadian property” under the Canadian Tax Act; or (e) persons that have a permanent establishment in Canada for the
purposes of the Canada-U.S. Tax Convention. U.S. Holders that are subject to special provisions under the Code, including, but not limited
to, U.S. Holders described immediately above, should consult their own tax advisors regarding the tax considerations relevant to the Common
Shares and Public Warrants.
If an entity or arrangement that is classified as a partnership (or other “pass-through”
entity) for U.S. federal income tax purposes holds Common Shares and Public Warrants, the U.S. federal income tax consequences to such
entity or arrangement and the partners (or other owners or participants) of such entity or arrangement generally will depend on the activities
of the entity or arrangement and the status of such partners (or owners or participants). This summary does not address the tax consequences
to any such partner (or owner or participant). Partners (or other owners or participants) of entities or arrangements that are classified
as partnerships or as “pass-through” entities for U.S. federal income tax purposes should consult their own tax advisors regarding
the U.S. federal income tax considerations relevant to the Common Shares and Public Warrants.
General Rules Applicable to the Exercise
and Disposition of Warrants
Exercise or Lapse of Warrants
Except as discussed below with respect to the cashless exercise of a Public Warrant,
a U.S. Holder generally will not recognize gain or loss upon the acquisition of a Common Share on the exercise of a Public Warrant for
cash. A U.S. Holder’s tax basis in a Common Share received upon exercise of the Public Warrant should be an amount equal to the
sum of the U.S. Holder’s tax basis in the Public Warrant exercised therefor and the exercise price. The U.S. Holder’s holding
period for a Common Share received upon exercise of the Public Warrant will begin on the date following the date of exercise (or possibly
the date of exercise) of the Public Warrant and will not include the period during which the U.S. Holder held the Public Warrant. If a
Public Warrant is allowed to lapse unexercised, a U.S. Holder that has otherwise received no proceeds with respect to such Public Warrant
generally will recognize a capital loss equal to such U.S. Holder’s tax basis in the Public Warrant. Deductions for capital losses
are subject to significant limitations under the Code.
Under the terms of a Public Warrant, a U.S. Holder may be permitted to undertake
a cashless exercise of the Public Warrant into Common Shares in certain circumstances. The U.S. federal income tax treatment of a cashless
exercise of Public Warrants into Common Shares is unclear, and the tax consequences of a cashless exercise could differ from the consequences
upon the exercise of a Public Warrant described in the preceding paragraph. U.S. Holders should consult their own tax advisors regarding
the U.S. federal income tax consequences of a cashless exercise of Public Warrants, including whether taxable gain or loss is recognized
in connection with such a cashless exercise.
Dispositions of Warrants
Subject to the PFIC rules discussed below, a U.S. Holder generally will recognize gain or loss on any sale, exchange, redemption or other taxable disposition of Public Warrants in an amount equal to the difference between (i) the U.S. dollar value of cash received plus the fair market value of any property received and (ii) such U.S. Holder’s adjusted tax basis in such Public Warrants. Any gain or
loss recognized by a U.S. Holder on a taxable disposition of Public Warrants generally will be capital gain or loss. A U.S. Holder’s initial tax basis in Public Warrants generally will be determined as described above "—Allocation of Purchase Price for Common Shares & Warrants" (subject to any adjustments provided under the PFIC rules, described below). Subject again to the PFIC rules, gain or loss recognized on such sale or other disposition generally will be
long-term capital gain or loss if, at the time of the sale or other disposition, the Public Warrants have been held for more than one year. Any gain or loss will generally be U.S. source for U.S. foreign tax credit purposes.
Preferential tax rates currently apply to long-term capital gain of a U.S. Holder that
is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gain of a U.S. Holder that is
a corporation. Deductions for capital losses are subject to significant limitations under the Code. If the Company is determined to be
a PFIC, any gain realized on the Public Warrants could be ordinary income under the rules discussed below.
Certain Adjustments to the Warrants
The terms of each Public Warrant provide for an adjustment to the number of
Common Shares for which the Public Warrant may be exercised or to the exercise price of the Public Warrant in certain events. An adjustment
which has the effect of preventing dilution generally is not taxable. A U.S. Holder of a Public Warrant would, however, be treated as
receiving a constructive distribution from NioCorp if, for example, the adjustment increases the holder’s proportionate interest
in NioCorp’s assets or earnings and profits (for instance, through an increase in the number of Common Shares that would be obtained
upon exercise of such Public Warrant) as a result of a distribution of cash or other property such as other securities to the holders
of the Common Shares which is taxable to the U.S. Holders of such shares as described under “—General Rules Applicable
to the Ownership and Disposition of Common Shares—Distributions on Common Shares” below. Such constructive distribution
would be subject to tax as described under that section in the same manner as if the U.S. Holder of such Public Warrant received a cash
distribution from NioCorp equal to the fair market value of such increased interest.
Allocation of Purchase Price for Common Shares & Warrants
Each Common Share and accompanying Public Warrants acquired together by a U.S. Holder are expected to be treated for U.S. federal income tax purposes as an investment unit consisting of (i) one Common Share, (ii) one Series A Public Warrant, and (iii) one half of an interest in a Series B Public Warrant (except for any case in which a fractional interest in a Public Warrant is rounded down and not issued (see discussion under
“ —No Fractional Warrants” above), in which case the treatment is not entirely clear but it is expected that the relevant investment unit would consist solely of Common Shares and any Public Warrants actually issued). For U.S. federal income tax purposes, each U.S. Holder must allocate the purchase price paid for such an investment unit among Common Shares and the accompanying interests in Public Warrants based on the relative fair market value of each acquired item at the time
of its issuance by the Company. This allocation will be used to establish the U.S. Holder's initial tax basis for U.S. federal income tax purposes in each such acquired item (subject to any adjustments provided under the PFIC rules, described below).
Under U.S. federal income tax law, a determination of value must be based on all the relevant facts and circumstances, and we strongly urge each acquiror of Common Shares and Public Warrants to consult with its tax advisor regarding the determination and allocation of value for these purposes, as well as the U.S. federal,
state, local and non-U.S. tax consequences of an investment in our securities. However, the IRS and the courts will not be bound by, and therefore may not respect, a holder's or advisor's purchase price allocation for these purposes.
General Rules Applicable to the Ownership and Disposition of Common Shares
Distributions on Common Shares
A U.S. Holder that receives a distribution,
including a constructive distribution, with respect to a Common Share will be required to include the amount of such distribution in
gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current
and accumulated “earnings and profits” of the Company, as computed for U.S. federal income tax purposes. To the extent that
a distribution exceeds the current and accumulated “earnings and profits” of the Company, such distribution will be treated,
first, as a tax-free return of capital to the extent of a U.S. Holder’s tax basis in the Common Shares and thereafter as gain from
the sale or exchange of such Common Shares. However, the Company may not maintain the calculations of its earnings and profits in accordance
with U.S. federal income tax principles, and U.S. Holders may have to assume that any distribution by the Company with respect to the
Common Shares will constitute ordinary dividend income in its entirety. Dividends received on Common Shares by a corporate U.S. Holder
(other than certain 10% corporate shareholders) generally will not be eligible for a “dividends received deduction.” Provided
that (1) the Company is eligible for the benefits of the Canada-U.S. Tax Convention or (2) the Common Shares are readily tradable on
a United States securities market (and certain holding period and other conditions are satisfied), dividends paid by the Company to non-corporate
U.S. Holders, including individuals, will be eligible for the preferential tax rates applicable to long-term capital gains for dividends
unless the Company is classified as a PFIC in the taxable year of distribution or in the preceding taxable year. See “—Passive
Foreign Investment Company Rules—Risk of PFIC Status for the Company” below. The dividend rules are complex, and
each U.S. Holder should consult its own tax advisors regarding the application of such rules.
Sales or Other Taxable Dispositions of
Common Shares
Upon the sale or other taxable disposition of Common Shares, subject to the potential application of the PFIC rules as described below, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between (i) the U.S. dollar value of cash received plus the fair market value of any property received and (ii) such U.S. Holder’s adjusted tax basis in such Common Shares
sold or otherwise disposed of. A U.S. Holder’s initial tax basis in Common Shares generally will be determined as described above "—Allocation of Purchase Price for Common Shares & Warrants" (subject to any adjustments provided under the PFIC rules, described below). Subject again to the PFIC rules, gain or loss recognized on such sale or other disposition generally will be long-term capital gain or loss if, at the time of the sale or other disposition, the
Common Shares have been held for more than one year. Any gain or loss will generally be U.S. source for U.S. foreign tax credit purposes.
Preferential tax rates currently apply to long-term
capital gain of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital
gain of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code. If the
Company is determined to be a PFIC, any gain realized on the Common Shares could be ordinary income under the rules discussed below.
Passive Foreign Investment Company Rules
Risk of PFIC Status for the Company
If the Company were to constitute a PFIC under the meaning of Section 1297 of the
Code for any taxable year during the holding period of a U.S. Holder of Common Shares or Public Warrants, then certain potentially adverse
U.S. federal income tax rules may apply to the U.S. Holder. While this summary cannot describe all of the potentially adverse consequences
that would result if the Company were treated as a PFIC for a relevant taxable year, certain material consequences and related considerations
are described below.
The Company believes that it was classified
as a PFIC during the taxable years ended June 30, 2024 and 2023, and, based on the current composition of its income and assets, as well
as current business plans and financial expectations, may meet the PFIC qualification tests for its current taxable year or in future
taxable years. No opinion of legal counsel or ruling from the IRS concerning the PFIC status of the Company or any subsidiary has been
obtained or is currently planned to be requested. The determination of whether any corporation was, or will be, a PFIC for a taxable year
depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. In addition,
whether any corporation will be a PFIC for any taxable year depends on the assets and income of such corporation over the course of each
such taxable year and, as a result, cannot be predicted with certainty as of the date of this document. In addition, even if the Company
concluded that it or any subsidiary did not qualify as a PFIC, the IRS could challenge any determination made by the Company (or any subsidiary
of the Company) concerning its PFIC status in any taxable year, and a court could sustain such challenge. Accordingly, there can be no
assurance that the Company or any subsidiary will not be treated as a PFIC for any taxable year. Each U.S. Holder should consult its own
tax advisors regarding the PFIC status of the Company and each subsidiary of the Company.
In any taxable year in which the Company is
classified as a PFIC, a U.S. Holder will be required to file an annual report with the IRS containing such information as Treasury Regulations
and/or other IRS guidance may require. IRS Form 8621 is currently used for such filings. In addition to penalties, a failure to satisfy
such reporting requirements may result in an extension of the time period during which the IRS can assess a tax. U.S. Holders should consult
their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file
an IRS Form 8621 annually.
The Company generally would be a PFIC for a particular taxable year if, for such year, (a) 75% or more of the gross income of the Company is passive income (the “PFIC income test”) or (b) 50% or more of the value of the Company’s assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the
“PFIC asset test”). “Gross income” generally includes all sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “passive income” generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded
from passive income if substantially all of a foreign corporation’s business is as an active producer, processor, merchant or handler of commodities, and certain other requirements are satisfied.
For purposes of the PFIC income test and PFIC
asset test described above, if the Company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another
corporation, the Company will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received
directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and PFIC asset
test described above, and assuming certain other requirements are met, “passive income” does not include certain interest,
dividends, rents, or royalties that are received or accrued by the Company from certain “related persons” (as defined in Section
954(d)(3) of the Code) also organized in Canada, to the extent such items are properly allocable to the income of such related person
that is neither passive income nor income connected with a U.S. trade or business.
Under certain attribution rules, if the Company is a PFIC, U.S. Holders will generally
be deemed to own their proportionate share of the Company’s direct or indirect equity interest in any company that is also a PFIC
(a “Subsidiary PFIC”), and will generally be subject to U.S. federal income tax on their proportionate share of (a) any “excess
distributions,” as described below, on the stock of a Subsidiary PFIC and (b) a disposition or deemed disposition of the stock of
a Subsidiary PFIC by the Company or another Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary
PFIC. In addition, U.S. Holders may be subject to U.S. federal income tax on any indirect gain realized on the stock of a Subsidiary PFIC
on the indirect sale or disposition thereof. Accordingly, U.S. Holders should be aware that they could be subject to tax under the PFIC
rules even if no distributions are received on the Common Shares and no redemptions or other dispositions of Common Shares or Public Warrants
are made.
Default PFIC Rules
If the Company is a PFIC for any taxable
year during which a U.S. Holder owns Common Shares or Public Warrants, the U.S. federal income tax consequences to such U.S. Holder
will depend on whether and when such U.S. Holder makes an election to treat the Company and each Subsidiary PFIC, if any, as a
“qualified electing fund” (“QEF”) under Section 1295 of the Code (a “QEF Election”) or makes a
mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”). A U.S. Holder that does not make
either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a “Non-Electing U.S.
Holder.”
A Non-Electing U.S. Holder will be subject to the rules of Section 1291 of
the Code (described below) with respect to (a) any gain recognized on the sale or other taxable disposition of Common Shares or Public
Warrants and (b) any “excess distribution” received on the Common Shares. A distribution generally will be an “excess
distribution” to the extent that such distribution (together with all other distributions received in the current taxable year)
exceeds 125% of the average distributions received during the three preceding taxable years (or during a U.S. Holder’s holding period
for the Common Shares, if shorter).
If the Company is a PFIC, under Section 1291 of the Code, any gain recognized on
the sale or other taxable disposition of Common Shares or Public Warrants (including an indirect disposition of the stock of any Subsidiary
PFIC), and any “excess distribution” received on Common Shares or deemed received with respect to the stock of a Subsidiary
PFIC, must be ratably allocated to each day in a Non-Electing U.S. Holder’s holding period for the respective Common Shares or Public
Warrants, as applicable. The amount of any such gain or excess distribution allocated to the taxable year of disposition or distribution
of the excess distribution, or allocated to years before the entity became a PFIC, if any, would be taxed as ordinary income at the rates
applicable for such year (and not eligible for certain preferential rates, as discussed below). The amounts allocated to any other taxable
year would be subject to U.S. federal income tax at the highest tax rate applicable to ordinary income in each such year. In addition,
an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each
such year. A Non-Electing U.S. Holder that is not a corporation must treat any such interest paid as “personal interest,”
which is not deductible.
If the Company is a PFIC for any taxable year
during which a Non-Electing U.S. Holder holds Common Shares, the Company will continue to be treated as a PFIC with respect to such Non-Electing
U.S. Holder, regardless of whether the Company ceases to be a PFIC in one or more subsequent taxable years. A Non-Electing U.S. Holder
may terminate this deemed PFIC status by making a “purging” election to recognize gain (which will be
taxed under the rules of Section 1291 of the Code discussed above),
but not loss, as if such Common Shares were sold on the last day of the last taxable year for which the Company was a PFIC.
In addition to the rules described above applying to “excess distributions”
and certain other dispositions of Common Shares or Public Warrants, certain other adverse U.S. federal income tax rules may apply with
respect to a U.S. Holder if the Company is a PFIC, including in some cases even if the U.S. Holder makes a QEF Election (as described
below). All of the non-PFIC rules described herein are subject to the potentially adverse consequences of PFIC status for the Company
and each subsidiary of the Company. Each U.S. Holder should consult its own tax advisors regarding the full tax consequences of potential
PFIC status for the Company and each subsidiary of the Company.
Under proposed Treasury Regulations, if a U.S. Holder has an option, warrant or
other right to acquire stock of a PFIC (such as a Public Warrant), such option, warrant or right is generally considered to be PFIC stock
subject to the default rules of Section 1291 of the Code. This rule could adversely affect the availability of the QEF Election and Mark-to-Market
Election with respect to Common Shares acquired on exercise of Public Warrants. (See discussion under “—QEF Election”
and “—Market-to-Market Election” below.) It is not entirely clear how various aspects of the PFIC rules would
apply to the Public Warrants, and U.S. Holders should consult their own tax advisors regarding the application of the PFIC rules to Public
Warrants and Common Shares acquired upon exercise of Public Warrants.
QEF Election
If the Company is a PFIC, a U.S. Holder of Common
Shares that makes a timely and effective QEF Election for the taxable year in which the holding period of its Common Shares begins generally
will not be subject to the rules of Section 1291 of the Code discussed above with respect to such Common Shares. A U.S. Holder that makes
such a QEF Election will be subject to U.S. federal income tax on such U.S. Holder’s pro rata share (based on its ownership of Common
Shares) of (a) the net capital gain of the Company, which will be taxed as long-term capital gain to such U.S. Holder, and (b) the ordinary
earnings of the Company, which will be taxed as ordinary income to such U.S. Holder. Generally, “net capital gain” is the
excess of (a) net long-term capital gain over (b) net short-term capital loss, and “ordinary earnings” are the excess of (a)
“earnings and profits” over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal
income tax on such amounts for each taxable year in which the Company is a PFIC, regardless of whether such amounts are actually distributed
to such U.S. Holder by the Company. However, for any taxable year in which the Company is a PFIC and has no net income or gain, U.S. Holders
that have made a QEF Election would not have any income inclusions as a result of the QEF Election. If a U.S. Holder that made a QEF Election
has an income inclusion, such a U.S. Holder may, subject to certain limitations, elect to defer payment of current U.S. federal income
tax on such amounts, subject to an interest charge. If such U.S. Holder is not a corporation, any such interest paid will be treated as
“personal interest,” which is not deductible.
A U.S. Holder that makes a timely and effective
QEF Election with respect to the Company generally (a) may receive a tax-free distribution from the Company to the extent that such distribution
represents “earnings and profits” of the Company that were previously included in income by the U.S. Holder because of such
QEF Election and (b) will adjust such U.S. Holder’s tax basis in the Common Shares to reflect the amount included in income or allowed
as a tax-free distribution because of such QEF Election. A U.S. Holder that makes a QEF Election generally will recognize capital gain
or loss on the sale or other taxable disposition of Common Shares.
A U.S. Holder may make a timely QEF Election
by filing the appropriate QEF Election documents (currently IRS Form 8621) at the time such U.S. Holder files a U.S. federal income tax
return for such year. If a U.S. Holder does not make a timely QEF Election for the first year in the U.S. Holder’s holding period
in which the Company is a PFIC, the U.S. Holder may still be able to make an effective QEF Election in a subsequent year if such U.S.
Holder meets certain requirements and makes a “purging” election to recognize gain (which will be taxed under the rules of
Section 1291 of the Code discussed above) as if such Common Shares were sold for their fair market value on the day the QEF Election is
effective. If a U.S. Holder makes a QEF Election but does not make a “purging” election to recognize gain as discussed in
the preceding sentence, then such U.S. Holder shall be subject to the QEF Election rules and shall continue to be subject to tax under
the rules of Section 1291 of the Code discussed above with respect to its Common Shares. If a U.S. Holder owns PFIC stock indirectly through
another PFIC, separate QEF Elections must be made for the PFIC in which the U.S. Holder is a direct shareholder and the Subsidiary PFIC
for the QEF rules to apply to both PFICs.
A QEF Election will apply to the taxable year
for which such QEF Election is timely made and to all subsequent taxable years, unless such QEF Election is invalidated or terminated
or the IRS consents to revocation of such QEF Election. If a U.S. Holder makes a QEF Election and, in a subsequent taxable year, the Company
ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those taxable years in which the
Company is not a PFIC. Accordingly, if the Company becomes a PFIC in another subsequent taxable year, the QEF Election will be effective,
and the U.S. Holder will be subject to the QEF rules described above during any subsequent taxable year in which the Company qualifies
as a PFIC.
As discussed above, under proposed Treasury Regulations, if a U.S. Holder has
an option, warrant or other right to acquire stock of a PFIC (such as a Public Warrant, if NioCorp is a PFIC), such option, warrant or
right is generally considered to be PFIC stock subject to the default rules of Section 1291 of the Code on its disposition. However, a
holder of an option, warrant or other right to acquire stock of a PFIC may not make a QEF Election that will apply to the option, warrant
or other right to acquire PFIC stock. If a U.S. Holder of Common Shares makes a QEF Election, such election may not be treated as a timely
QEF Election with respect to Common Shares subsequently acquired on the exercise of Public Warrants, and the rules of Section 1291 of
the Code discussed above may continue to apply with respect to such U.S. Holder’s previously owned Common Shares. In addition, gain
recognized on the sale or other taxable disposition (other than by exercise) of the Public Warrants by a U.S. Holder will be subject to
the rules of Section 1291 of the Code discussed above. U.S. Holders should consult their own tax advisors regarding the application of
the PFIC rules to Public Warrants and Common Shares acquired upon exercise of Public Warrants.
The Company will endeavor to provide U.S. Holders
with the required information to allow U.S. Holders to make a QEF Election with respect to the Common Shares in the event that the Company
determines it is treated as a PFIC for any taxable year. There can be no assurance, however, that the Company will timely provide such
information for any particular year, or that the Company’s determination regarding its PFIC status will be upheld. U.S. Holders
should consult their tax advisors to determine whether any of these QEF Elections will be available and if so, what the consequences of
these elections would be in their particular circumstances.
A U.S. Holder makes a QEF Election by attaching
a completed IRS Form 8621, including a PFIC Annual Information Statement, to a timely filed United States federal income tax return. However,
if the Company does not timely provide the required information with regard to the Company or any of its Subsidiary PFICs, U.S. Holders
may not be able to make a QEF Election for such entity and, unless they make the Mark-to-Market Election discussed in the next section,
will continue to be subject to the rules of Section 1291 of the Code discussed above that apply to Non-Electing U.S. Holders with respect
to the taxation of gains and excess distributions.
Mark-to-Market Election
A U.S. Holder may make a Mark-to-Market Election
only with respect to Common Shares and only if the Common Shares are marketable stock. The Common Shares generally will be “marketable
stock” if the Common Shares are regularly traded on (a) a national securities exchange that is registered with the SEC, (b) the
national market system established pursuant to Section 11A of the Exchange Act, or (c) a foreign securities exchange that is regulated
or supervised by a governmental authority of the country in which the market is located, provided that the foreign exchange meets certain
trading volume and other requirements. If such stock is traded on such a qualified exchange or other market, such stock generally will
be “regularly traded” for any calendar year during which such stock is traded, other than in de minimis quantities, on at
least 15 days during each calendar quarter. The Company expects that the Common Shares will meet the definition of “marketable stock,”
although there can be no assurance of this, especially as regards the required trading frequency.
If a U.S. Holder that makes a Mark-to-Market
Election for any taxable year with respect to its Common Shares, it generally will not be subject to the rules of Section 1291 of the
Code discussed above with respect to such Common Shares for such taxable year. However, if a U.S. Holder does not make a Mark-to-Market
Election beginning in the first taxable year of such U.S. Holder’s holding period for which the Company is a PFIC and such U.S.
Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of,
and certain distributions on, the Common Shares.
Any Mark-to-Market Election made by a U.S. Holder for Common Shares will also
apply to such U.S. Holder’s Common Shares acquired upon exercise of Public Warrants. As a result, if a Market-to-Market Election
has been made by a U.S. Holder with respect to Common Shares, any Common Shares received on exercise of Public Warrants will
automatically be marked-to-market in the year of exercise. If the Company is a PFIC at
the time a U.S. Holder acquires Public Warrants, a U.S. Holder’s holding period for Common Shares received on exercise of such Public
Warrants should include the period during which such U.S. Holder has held the Public Warrants. In these circumstances, a U.S. Holder will
be treated as making a Mark-to-Market Election with respect to its Common Shares acquired on exercise of the Public Warrants after the
beginning of such U.S. Holder’s holding period for such Common Shares, unless the Common Shares are acquired in the same taxable
year as the year in which the U.S. Holder acquired the corresponding Public Warrants, and the tax regime and interest charge of Section
1291 described above generally will apply to the mark-to-market gain realized in the taxable year in which the Common Shares are received.
However, the general mark-to-market rules will apply to subsequent taxable years. A U.S. Holder that makes a Mark-to-Market Election will
include in ordinary income, for each taxable year in which the Company is a PFIC, an amount equal to the excess, if any, of (a) the fair
market value of the Common Shares, as of the close of such taxable year over (b) such U.S. Holder’s adjusted tax basis in such Common
Shares. A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (a)
such U.S. Holder’s adjusted tax basis in the Common Shares, over (b) the fair market value of such Common Shares (but only to the
extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior taxable years).
A U.S. Holder that makes a Mark-to-Market Election
will also generally adjust its tax basis in the Common Shares to reflect the amount included in gross income or allowed as a deduction
because of such Mark-to-Market Election. Upon a sale or other taxable disposition of Common Shares, a U.S. Holder that makes a Mark-to-Market
Election will recognize ordinary income or ordinary loss (and such ordinary loss may be treated as capital or subject to limitations in
certain cases).
A U.S. Holder makes a Mark-to-Market Election
by attaching a completed IRS Form 8621 to a timely filed United States federal income tax return. A Mark-to-Market Election applies to
the taxable year in which such Mark-to-Market Election is made and to each subsequent taxable year, unless the Common Shares cease to
be “marketable stock” or the IRS consents to revocation of such election. Each U.S. Holder should consult its own tax advisors
regarding the requirements for, and procedure for making, a Mark-to-Market Election.
Although a U.S. Holder may be eligible to make
a Mark-to-Market Election with respect to the Common Shares, no such election may be made with respect to the stock of any Subsidiary
PFIC that a U.S. Holder is treated as owning, because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective
to avoid the application of the default rules of Section 1291 of the Code described above with respect to deemed dispositions of Subsidiary
PFIC stock or excess distributions from a Subsidiary PFIC to its shareholder.
AS THE PFIC RULES ARE COMPLEX AND UNCERTAIN, U.S. HOLDERS SHOULD CONSULT WITH
THEIR TAX ADVISORS TO DETERMINE THE POTENTIAL APPLICATION OF THE PFIC RULES TO THEM AND THEIR COMMON SHARES AND PUBLIC WARRANTS AND ANY
RESULTANT TAX CONSEQUENCES.
Additional Considerations
Receipt of Foreign Currency
The amount of any distribution paid to a U.S. Holder in foreign currency, or
on the sale, exchange or other taxable disposition of Common Shares or Public Warrants, generally will be equal to the U.S. dollar value
of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is
converted into U.S. dollars at that time). A U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the
date of receipt. Any U.S. Holder who converts or otherwise disposes of the foreign currency after the date of receipt may have a foreign
currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for
foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. Each U.S. Holder should
consult its own U.S. tax advisors regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.
Foreign Tax Credit
Subject to the potential application of the
PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends
paid on the Common Shares
generally will be entitled, at the election of such U.S. Holder,
to receive either a deduction or a credit for such Canadian income tax. Generally, a credit will reduce a U.S. Holder’s U.S. federal
income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income that is subject to U.S.
federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding)
by a U.S. Holder during a year.
Complex limitations apply to the foreign tax credit, including the general limitation
that the credit cannot exceed the proportionate share of a U.S. Holder’s U.S. federal income tax liability that such U.S. Holder’s
“foreign source” taxable income bears to such U.S. Holder’s worldwide taxable income. In applying this limitation, a
U.S. Holder’s various items of income and deduction must be classified, under complex rules, as either “foreign source”
or “U.S. source.” Generally, dividends paid on the Common Shares should be treated as foreign source for this purpose, and
gains recognized on the sale of Common Shares or Public Warrants by a U.S. Holder should be treated as U.S. source for this purpose, except
as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a
distribution with respect to the Common Shares that is treated as a “dividend” may be lower for U.S. federal income tax purposes
than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. Holder. In addition,
this limitation is calculated separately with respect to specific categories of income. The foreign tax credit rules are complex, and
each U.S. Holder should consult its own U.S. tax advisors regarding the foreign tax credit rules.
Information Reporting and Backup Withholding
Certain U.S. Holders may be subject to certain reporting obligations with respect
to Common Shares or Public Warrants if the aggregate value of these and certain other “specified foreign financial assets”
exceeds an applicable dollar threshold. If required, this disclosure is made by filing Form 8938 with the IRS. Significant penalties can
apply if a U.S. Holder is required to make this disclosure and fails to do so. In addition, a U.S. Holder should consider the possible
obligation to file online a FinCEN Form 114—Foreign Bank and Financial Accounts Report, as a result of holding Common Shares or
Public Warrants in certain accounts. Holders are urged to consult their U.S. tax advisors with respect to these and other reporting requirements
that may apply to their acquisition of Common Shares or Public Warrants.
Dividend payments (including constructive dividends) with respect to Common Shares
and proceeds from the sale, exchange or redemption of Common Shares or Public Warrants may be subject to information reporting to the
IRS and possible United States backup withholding. Backup withholding (currently at a rate of 24%) will not apply, however, to a U.S.
Holder who furnishes a correct taxpayer identification number (generally on an IRS Form W-9 provided to the paying agent of the U.S. Holder’s
broker) and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status.
Backup withholding is not an additional tax. Any amounts withheld under the U.S. backup withholding tax rules may be allowed as a credit
against a U.S. Holder’s U.S. federal income tax liability, if any, provided the required information is timely furnished to the
IRS.
THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX
CONSIDERATIONS RELEVANT OR APPLICABLE TO U.S. HOLDERS OF COMMON SHARES OR PUBLIC WARRANTS. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS
AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN THEIR OWN PARTICULAR CIRCUMSTANCES.
CERTAIN
CANADIAN FEDERAL INCOME TAX CONSIDERATIONS FOR U.S. RESIDENTS
The following generally summarizes certain Canadian federal income tax consequences
generally applicable under the Income Tax Act (Canada) and the regulations enacted thereunder (collectively, the “Canadian
Tax Act”) and the Canada-United States Tax Convention (1980) (the “Convention”) to the holding and disposition of Common
Shares or Public Warrants.
Comment is restricted to holders of Common Shares or Public Warrants each of whom,
at all material times for the purposes of the Canadian Tax Act and the Convention, (i) is resident solely in the United States for tax
purposes, (ii) acquires, as beneficial owner, pursuant to this prospectus supplement, the Common Shares and Public Warrants, (iii) is
a “qualifying person” under and entitled to the benefits of the Convention, (iv) holds all Common Shares and Public Warrants
as capital property, (v) deals at arm’s length with and is not affiliated with NioCorp or the underwriter, (vi) does not and is
not deemed to use or hold any Common Shares or Public Warrants in a business carried on in Canada, (vii) is not an insurer that carries
on business in Canada and elsewhere, (viii) is not an “authorized foreign bank” (as defined in the Canadian Tax Act), and
(ix) has not entered into a “derivative forward agreement” (as defined in the Canadian Tax Act) with respect to the Common
Shares or Public Warrants (each such holder, a “U.S. Resident Holder”).
Certain U.S.-resident entities that are fiscally transparent for United States federal
income tax purposes (including limited liability companies) may not in all circumstances be entitled to the benefits of the Convention.
Members of or holders of an interest in such an entity that holds Common Shares or Public Warrants should consult their own tax advisers
regarding the extent, if any, to which the benefits of the Convention will apply to the entity in respect of its Common Shares or Public
Warrants.
Generally, a U.S. Resident Holder’s Common Shares or Public Warrants will be
considered to be capital property of such holder provided that the U.S. Resident Holder is not a trader or dealer in securities, did not
acquire, hold, or dispose of the Common Shares or Public Warrants in one or more transactions considered to be an adventure or concern
in the nature of trade (i.e., speculation) and does not hold the Common Shares or Public Warrants in the course of carrying on a business.
This summary is based on the facts set out in
this prospectus supplement, the current provisions of the Canadian Tax Act and the Convention in effect as of the date prior to the date
hereof, all specific proposals to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance
(Canada) prior to the date hereof, and the current published administrative policies and assessing practices of the Canada Revenue Agency
(the “CRA”). It is assumed that all such amendments will be enacted as currently proposed, and that there will be no other
material change to any applicable law or administrative policy or assessing practice, whether by way of judicial, legislative or governmental
decision or action, although no assurance can be given in these respects. This summary is not exhaustive of all possible Canadian federal
income tax considerations. Except as otherwise expressly provided, this summary does not take into account any provincial, territorial,
or foreign tax considerations, which may differ materially from those set out herein.
This summary is of a general nature only, is not exhaustive of all possible Canadian
federal income tax considerations, and is not intended to be and should not be construed as legal or tax advice to any particular U.S.
Resident Holder. The tax consequences of acquiring, holding and disposing of Common Shares or Public Warrants will vary according
to the U.S. Resident Holder’s particular circumstances. U.S. Resident Holders are urged to consult their own tax advisers for advice
with respect to their particular circumstances. The discussion below is qualified accordingly.
Currency Conversion
In general, for purposes of the Canadian Tax Act, all amounts relating to the
acquisition, holding or disposition of Common Shares and Public Warrants must be converted into Canadian dollars based on the relevant
exchange rate as determined in accordance with the Canadian Tax Act.
Allocation of Purchase Price
To the extent that the purchase price for the Common Shares and Public Warrants is combined, U.S. Resident Holders will be required to allocate on a reasonable basis their aggregate cost of the Common Shares and Public Warrants between the Common Shares, the Series A Public Warrants and the Series B Public Warrants in order to determine their respective costs to the U.S. Resident Holders for purposes of the Canadian Tax Act.
For purposes of the Canadian Tax Act, in the case of a standard acquisition where a U.S. Resident Holder acquires a single Common Share, a single Series A Public Warrant, and a half-interest in a Series B Public Warrant, NioCorp intends to allocate $1.205 as consideration for the issue of the Common Share, $0.21 as consideration for the issue of the Series A Public Warrant and $0.155 as consideration for the issue of the half-interest in the Series B Public Warrant. Although NioCorp believes that its allocation
is reasonable, it is not binding on the CRA (or any other government authority in any jurisdiction) or the U.S. Resident Holder and the CRA may not agree with such allocation and counsel expresses no opinion with respect to such allocation. U.S. Resident Holders should consult their own tax advisers in this regard.
Exercise of Warrants
No gain or loss will be realized by a U.S. Resident Holder upon the exercise
or deemed exercise of a Public Warrant to acquire a Common Share. When a Public Warrant is exercised or deemed to be exercised, the cost
of the Common Share acquired by the U.S. Resident Holder on exercise of the Public Warrant will be the aggregate of the U.S. Holder’s
adjusted cost base of such Public Warrant and the exercise price paid to acquire the Common Share. The adjusted cost base of the Common
Share acquired by the U.S. Resident Holder on exercise of the Public Warrant will be determined by averaging the cost of such Common Share
with the adjusted cost base to the U.S. Resident Holder of all Common Shares held by the U.S. Resident Holder as capital property (if
any) immediately prior to such acquisition.
Disposition of Common Shares and Warrants and Expiry of Warrants
A U.S. Resident Holder will not be subject to tax under the Canadian Tax Act
in respect of any capital gain realized on a disposition or deemed disposition of a Common Share or Public Warrant unless the Common Share
or Public Warrant is “taxable Canadian property” of the U.S. Resident Holder for the purposes of the Canadian Tax Act at the
time of disposition and the U.S. Resident Holder is not entitled to an exemption under the Convention. In addition, capital losses arising
on a disposition or deemed disposition of a Public Warrant (including on expiry of a Public Warrant) or a Common Share will not be recognized
under the Canadian Tax Act, unless the Public Warrant or Common Share constitutes “taxable Canadian property” (as defined
in the Canadian Tax Act) at the time of disposition and the U.S. Resident Holder is not entitled to relief under the Convention.
Generally, a U.S. Resident Holder’s Common Shares or Public Warrants will not
constitute “taxable Canadian property” of such holder at a particular time at which the Common Shares are listed on a “designated
stock exchange” (which currently includes the Nasdaq) unless, at any time during the 60-month period that ends at the particular
time both of the following conditions are concurrently met:
|
(i) |
25% or more of the issued shares of any class of the capital stock of NioCorp were owned by or belonged to one or any combination of |
|
(A) |
the U.S. Resident Holder, |
|
(B) |
persons with whom the U.S. Resident Holder did not deal at arm’s length, and |
| (C) | partnerships in which the U.S. Resident Holder or a person referred to in clause (B) holds a membership interest directly or indirectly
through one or more partnerships, and |
| (ii) | more than 50% of the fair market value of the Common Shares was derived directly or indirectly from, one or any combination of, real
or immovable property situated in Canada, “Canadian resource properties” (as defined in the Canadian Tax Act), “timber
resource properties” (as defined in the Canadian Tax Act), or options in respect of, or interests in any of the foregoing, whether
or not the property exists. |
Notwithstanding the foregoing, Common Shares or Public Warrants may also be deemed to be
“taxable Canadian property” in certain circumstances set out in the Canadian Tax Act.
Dividends on Common Shares
A U.S. Resident Holder to whom NioCorp pays
or credits or is deemed to pay or credit a dividend on such holder’s Common Shares will be subject to Canadian withholding tax,
and NioCorp will be required to withhold the tax from the dividend and remit it to the CRA for the holder’s account. The rate of
withholding tax under the
Canadian Tax Act is 25% of the gross amount of the dividend, but
should generally be reduced under the Convention to 15% (or, if the U.S. Resident Holder is a company which is the beneficial owner of
at least 10% of the voting stock of NioCorp, 5%) of the gross amount of the dividend. For this purpose, a company that is a resident of
the United States for purposes of the Canadian Tax Act and the Convention and is entitled to the benefits of the Convention shall be considered
to own the voting stock of NioCorp owned by an entity that is considered fiscally transparent under the laws of the United States and
that is not a resident of Canada, in proportion to such company’s ownership interest in that entity.
underwriting
Maxim Group LLC (“Maxim” or the “underwriter”) is acting
as the underwriter of this offering. We have entered into an underwriting agreement dated November 3, 2024 with the underwriter (the “underwriting agreement”). Subject to the terms and conditions of the underwriting agreement,
we have agreed to sell to the underwriter, and the underwriter has agreed to purchase, at the public offering price less the underwriting
discounts and commissions set forth on the cover page of this prospectus supplement, the following numbers of our Common Shares and Public
Warrants:
Underwriter | |
Number of Common Shares | |
Number of Series A Public Warrants | |
Number of Series B Public Warrants |
Maxim Group LLC | |
| 1,592,356 | | |
| 1,592,356 | | |
| 796,178 | |
TOTAL | |
| 1,592,356 | | |
| 1,592,356 | | |
| 796,178 | |
The underwriter is committed
to purchase all the Common Shares and associated Public Warrants offered hereby, other than those covered by the over-allotment
option to purchase Option Shares and/or Option Warrants described below, if it purchases any Common Shares. The obligations of the
underwriter may be terminated upon the occurrence of certain events specified in the underwriting agreement. Furthermore, pursuant
to the underwriting agreement, the underwriter’s obligations are subject to customary conditions, representations and
warranties contained in the underwriting agreement, such as receipt by the underwriter of officer’s certificates and legal
opinions.
Delivery of the Common Shares and Public Warrants (other than any Option Shares or
Option Warrants) offered hereby is expected on or about November 5, 2024, against payment in immediately available funds and subject to customary closing conditions.
We have agreed to indemnify the underwriter
against certain liabilities, including liabilities under the Securities Act and liabilities arising from breaches of representations and
warranties contained in the underwriting agreement, or to contribute to payments that the underwriter may be required to make in respect
of those liabilities.
The underwriter is offering
the Common Shares and Public Warrants subject to various conditions and may reject all or part of any order. The underwriter has advised
us that it proposes to offer the Common Shares and Public Warrants directly to the public at the public offering price that appears on
the cover page of this prospectus supplement. In addition, the underwriter may offer some of the Common Shares and Public Warrants to other securities dealers at such price less a
concession of up to $0.05495 per Common Share and associated Public Warrants.
Over-Allotment Option
We have granted the underwriter an over-allotment option. The over-allotment
option, which is exercisable for up to 45 days following the execution date of the underwriting agreement, permits the underwriter to
purchase (i) up to an aggregate of 238,853 Option Shares (equal to 15% of the aggregate
number of initial Common Shares offered hereby) and/or (ii) 358,280 Option Warrants
(equal to 15% of the aggregate number of initial Public Warrants offered hereby). If the underwriter exercises all or part of the over-allotment
option, it will purchase Option Shares and/or Option Warrants covered by the over-allotment option at the public offering prices that
appear on the cover page of this prospectus supplement, less the applicable underwriting discounts and commissions, if any. If the underwriter
exercises the over-allotment option to purchase Option Shares and Option Warrants in full, without giving effect to the exercise of any
Public Warrants, the total proceeds to us from this offering, before expenses payable by
us, will be approximately $2,874,999,
assuming no sales to persons on the President’s List or to any person who is a director or officer of the Company.
Underwriting Discounts and Commissions
The following table provides information
regarding the amount of the underwriting discounts and commissions to be paid to the underwriter by us and the proceeds, before expenses,

Common Shares and the Public Warrants sold to any person on the President’s List is 4.20%. There is no underwriting discount on
the public offering price of the Common Shares and the Public Warrants sold to any person who is a director or officer of the Company. |
| (2) | Assumes no sales to persons on the President’s List or to any person who is
a director or officer of the Company and does not give effect to the exercise of any Public Warrants offered hereby. |
We estimate that our total expenses
of this offering, excluding the estimated underwriting discounts and commissions, will be approximately $940,000, which includes up to $100,000
that we have agreed to reimburse the underwriter for the fees and expenses incurred by it and its legal counsel in connection with this
offering.
Lock-Up Agreements
Our executive officers and directors, have agreed
to a 90-day “lock-up” with respect to the Common Shares and other of our securities such parties beneficially own, including
securities that are convertible into Common Shares and securities that are exchangeable or exercisable for Common Shares, subject to certain
exceptions. This means that, subject to certain exceptions, for a period of 90 days following the date of the underwriting agreement,
such persons may not offer, sell, contract to sell, hypothecate, pledge or otherwise dispose of (or enter into any transaction which is
designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition
due to cash settlement or otherwise) by such persons or any of their affiliates), directly or indirectly, or establish or increase a put
equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, with respect
to, any such securities without the prior written consent of Maxim.
In addition, subject to certain exceptions,
we have agreed, (i) for a period of 90 days following the date of the closing of the offering, not to, and to cause our subsidiaries not
to, issue, enter into any agreement to issue or announce the issuance or proposed issuance of any Common Shares or any securities that
are convertible into, or
exchangeable or exercisable for, Common Shares and (ii) for a period
of 90 days following the date of the
closing of the offering, issue any securities that are subject to a price reset based on the trading prices of our Common Shares or upon
a specified or contingent event in the future, or enter into any agreement to issue securities at a future determined price. The foregoing
restrictions may be waived by Maxim at its discretion, although Maxim has no present intention to waive or shorten any of such restrictive
periods.
Other Compensation
We have agreed that, upon the
closing of this offering, for a period of 12 months from such closing, we will grant
Maxim a right of first refusal to act as sole managing underwriter and sole book runner, sole placement agent or sole sales agent for
any and all future public or private equity, equity-linked, convertible or debt offerings of ours or any successor to or any subsidiary
of ours during such 12-month period, subject to certain exceptions.
In the event that any investor
whom Maxim had contacted or introduced to us during the term of its engagement provides any capital to us, in a public or private offering
or other financing or capital-raising transaction of any kind, within the 12 months following the earlier of (a) the closing of this offering
and (b) the expiration or termination of the engagement of Maxim, subject to certain conditions and exceptions, we will pay Maxim the
cash compensation provided above, calculated in the same manner.
Electronic Offer, Sale and Distribution
of Shares
A prospectus supplement in electronic
format may be made available on the website maintained by the underwriter or selling group members. The underwriter may agree to allocate
a number of securities to the selling group members for sale to its online brokerage account holders. Internet distributions will be allocated
by the underwriter and selling group members that will make internet distributions on the same basis as other allocations. Other than
the prospectus supplement in electronic format, the information on these websites is not part of, nor incorporated by reference into,
this prospectus supplement or the registration statement of which this prospectus supplement forms a part, has not been approved or endorsed
by us, and should not be relied upon by investors.
Stabilization
The underwriter has advised us that it, pursuant
to Regulation M under the Exchange Act, and certain persons participating in the offering may engage in short sale transactions, stabilizing
transactions, syndicate covering transactions or the imposition of penalty bids in connection with this offering. These activities may
have the effect of stabilizing or maintaining the market price of the Common Shares at a level above that which might otherwise prevail
in the open market. Establishing short sales positions may involve either “covered” short sales or “naked” short
sales.
A stabilizing bid is a bid for the purchase
of the Common Shares on behalf of the underwriter for the purpose of fixing or maintaining the price of the Common Shares. A syndicate
covering transaction is the bid for or the purchase of Common Shares on behalf of the underwriter to reduce a short position incurred
by the underwriter in connection with the offering. Similar to other purchase transactions, the underwriter’s purchases to cover
the syndicate short sales may have the effect of raising or maintaining the market price of the Common Shares or preventing or retarding
a decline in the market price of the Common Shares. As a result, the price of the Common Shares may be higher than the price that might
otherwise exist in the open market. A penalty bid is an arrangement permitting the underwriter to reclaim the selling concession otherwise
accruing to a syndicate member in connection with the offering if the Common Shares originally sold by such syndicate member are purchased
in a syndicate covering transaction and therefore have not been effectively placed by such syndicate member.
Neither the Company nor the underwriter make
any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the
price of the Common Shares. The
underwriter is not obligated to engage in these activities and,
if commenced, any of the activities may be discontinued at any time.
Passive Market Making
The underwriter may also engage in passive market
making transactions in the Common Shares on Nasdaq in accordance with Rule 103 of Regulation M during a period before the commencement
of offers or sales of the Common Shares in this offering and extending through the completion of distribution. A passive market maker
must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered
below the passive market maker’s bid, that bid must then be lowered when specified purchase limits are exceeded.
Other Relationships
The underwriter and its affiliates may provide
from time to time in the future, certain commercial banking, financial advisory, investment banking and other services to the Company
and its affiliates in the ordinary course of their business, for which they may receive customary fees and commissions. From time to time,
the underwriter and its affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves
or their customers, long or short positions in the Company’s debt or equity securities or loans.
Listing
The Common Shares
are listed for trading on the Nasdaq Global Market under the symbol “NB.”

belief, result in compliance with any applicable laws and regulations and all offers and sales of securities by it will be made on the

NioCorp Developments
Ltd.
NioCorp is developing the Elk Creek Project (as defined
below) located in southeast Nebraska. The “Elk Creek Project” is a development-stage property that has disclosed niobium,
scandium, and titanium reserves and resources and disclosed rare earth mineral resources. The Company is continuing technical and economic
studies around the rare earths contained in the Elk Creek Project’s mineral resource in order to determine whether extraction of
rare earth elements can be reasonably justified and economically viable after taking into account all relevant factors. Niobium is used
to produce various superalloys that are extensively used in high performance aircraft and jet turbines. It also is used in high-strength,
low-alloy steel, a stronger steel used in automobiles, bridges, structural systems, buildings, pipelines, and other applications that
generally increases strength and/or reduces weight, which can result in environmental benefits, including reduced fuel consumption and
material usage and fewer air emissions. Scandium can be combined with aluminum to make high-performance alloys with increased strength
and improved corrosion resistance. Scandium also is a critical component of advanced solid oxide fuel cells, an environmentally preferred
technology for high-reliability, distributed electricity generation. Titanium is a component of various superalloys and other applications
that are used for aerospace applications, weapons systems, protective armor, medical implants, and many others. It also is used in pigments
for paper, paint, and plastics. Rare earths are critical to electrification and decarbonization initiatives and can be used to manufacture
the strongest permanent magnets commercially available.
Our primary business strategy is to advance our Elk
Creek Project to commercial production. We are focused on obtaining additional funds to carry out our near-term planned work programs
associated with securing the project financing necessary to complete mine development and construction of the Elk Creek Project.

Risk Factors

operations and financial condition could suffer and could result in a complete loss of your investment.
Cautionary Note Regarding Forward-Looking Statements
This prospectus
and the other documents incorporated by reference into this prospectus contain or may contain “forward-looking statements”
within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, and “forward-looking information”
within the meaning of applicable Canadian securities legislation (collectively, “forward-looking statements”). Such forward-looking
statements concern our anticipated results and developments in the operations of the Company in future periods, planned exploration activities,
the adequacy of the Company’s financial resources, and other events or conditions that may occur in the future.
Forward-looking
statements have been based upon our current business and operating plans, as approved by the Company’s Board of Directors, and may
include statements regarding the anticipated benefits of the transactions contemplated by the Business Combination Agreement (the “Business
Combination Agreement”), dated September 25, 2022, between NioCorp, GXII, Big Red Merger Sub Ltd, a Delaware corporation and a direct,
wholly owned subsidiary of the Company (the “Transactions”), including NioCorp’s ability to access the full amount of
the expected net proceeds of the Standby Equity Purchase Agreement, dated January 26, 2023 (as amended, the “Yorkville Equity Facility
Financing Agreement”), between NioCorp and YA II PN, Ltd. (“YA”), a fund managed by Yorkville Advisors Global, LP, through
April 1, 2026; NioCorp’s ability to receive a final commitment of financing from the Export-Import Bank of the United States (“EXIM”);
anticipated benefits of the listing of the Common Shares on Nasdaq; the financial and business performance of NioCorp; NioCorp’s
anticipated results and developments in the operations of NioCorp in future periods; NioCorp’s planned exploration and development
activities; the adequacy of NioCorp’s financial resources; NioCorp’s ability to secure sufficient project financing to complete
construction and commence operation of the Elk Creek Project; NioCorp’s expectation and ability to produce niobium, scandium, and
titanium at the Elk Creek Project; NioCorp’s plans to produce and supply specific products and market demand for those products;
the Elk Creek Project’s ability to produce multiple critical metals; NioCorp’s expectation that the process improvements resulting
from previously completed recovery process improvement testing could lead to greater efficiencies and cost savings in the Elk Creek Project;
the Elk Creek Project’s projected ore production and mining operations over its expected mine life; the completion and content of
an updated technical report for the Elk Creek Project; the completion of technical and economic analyses on the potential addition of
magnetic rare earth oxides to NioCorp’s planned product suite; anticipated benefits of the electrification of access to the Elk
Creek Project mine site; the exercise of options to purchase additional land parcels; the execution of contracts with engineering, procurement
and construction companies; the advancement of offtake discussions with potential customers; NioCorp’s ongoing evaluation of the
impact of inflation, supply chain issues and geopolitical unrest on the Elk Creek Project’s economic model; and the creation of
full time and contract construction jobs over the construction period of the Elk Creek Project.
Forward-looking
statements are frequently, but not always, identified by words such as “expects,” “anticipates,” “believes,”
“intends,” “estimates,” “potential,” “possible,” and similar expressions, or statements
that events, conditions, or results “will,” “may,” “could,” or “should” (or the negative
and grammatical variations of any of these terms) occur or be achieved. Any statements that express or involve discussions with respect
to predictions, expectations, beliefs, plans, projections, objectives, assumptions, or future events or performance (often, but not always,
using words or phrases such as “expects” or “does not expect,” “is expected,” “anticipates”
or “does not anticipate,” “plans,” “estimates,” or “intends,” or stating that certain
actions, events, or results “may,” “could,” “would,” “might,” or “will” be
taken, occur or be achieved) are not statements of historical fact and may be forward-looking statements. Such forward-looking statements
reflect the Company’s current views with respect to future events and are subject to certain known and unknown risks, uncertainties,
and assumptions. Many factors could cause actual results, performance, or achievements to be materially different from any future results,
performance, or achievements that may be expressed or implied by such forward-looking statements, including, among others, risks related
to the following: NioCorp’s ability to recognize the anticipated benefits of the Transactions, including NioCorp’s ability
to access the full amount of the expected net proceeds under the Yorkville Equity Facility Financing Agreement through April 1, 2026;
unexpected costs related to the Transactions; the outcome of any legal proceedings that may be instituted against NioCorp following closing
of the Transactions; NioCorp’s ability to receive a final commitment of financing from EXIM on the anticipated timeline, on acceptable
terms, or at all; NioCorp’s ability to continue to meet Nasdaq listing standards; NioCorp’s ability to operate as a going
concern; risks relating to the Common Shares, including price volatility, lack of dividend payments and dilution or the perception of
the likelihood any of the foregoing; NioCorp’s requirement of significant additional capital; the extent to which NioCorp’s
level of indebtedness and/or the terms contained in agreements governing NioCorp’s indebtedness or the Yorkville Equity Facility
Financing Agreement may impair NioCorp’s ability to obtain additional financing, on acceptable terms, or at all; covenants contained
in agreements with NioCorp’s secured creditors that may affect its assets; NioCorp’s limited operating history; NioCorp’s
history of losses; the material weaknesses in NioCorp’s internal control over financial reporting, NioCorp’s efforts to remediate
such material weaknesses and the timing of remediation; the possibility that NioCorp may qualify as a passive foreign investment company
(“PFIC”) under the U.S. Internal Revenue Code of 1986, as amended (the “Code”); the potential that the Transactions
could result in NioCorp becoming subject to materially adverse U.S. federal income tax consequences as a result of the application of
Section 7874 and related sections of the Code; cost increases for NioCorp’s exploration and, if warranted, development projects;
a disruption in, or failure of, NioCorp’s information technology systems, including those related to cybersecurity; equipment and
supply shortages; variations in the market demand for, and prices of, niobium, scandium, titanium and rare earth products; current and
future offtake agreements, joint ventures, and partnerships; NioCorp’s ability to attract qualified management; the effects of
global health crises on NioCorp’s business plans, financial condition and liquidity; estimates of mineral resources and reserves;
mineral exploration and production activities; feasibility study results; the results of metallurgical testing; the results of technological
research; changes in demand for and price of commodities (such as fuel and electricity) and currencies; competition in the mining industry;
changes or disruptions in the securities markets; legislative, political or economic developments, including changes in federal and/or
state laws that may significantly affect the mining industry; the impacts of climate change, as well as actions taken or required by
governments related to strengthening resilience in the face of potential impacts from climate change; the need to obtain permits and
comply with laws and regulations and other regulatory requirements; the timing and reliability of sampling and assay data; the possibility
that actual results of work may differ from projections/expectations or may not realize the perceived potential of NioCorp’s projects;
risks of accidents, equipment breakdowns, and labor disputes or other unanticipated difficulties or interruptions; the possibility of
cost overruns or unanticipated expenses in development programs; operating or technical difficulties in connection with exploration,
mining, or development activities; the management of the water balance at the Elk Creek Project site; land reclamation requirements related
to the Elk Creek Project; the speculative nature of mineral exploration and development, including the risks of diminishing quantities
of grades of reserves and resources; claims on the title to NioCorp’s properties; potential future litigation; and NioCorp’s
lack of insurance covering all of NioCorp’s operations.
Should
one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially
from those described herein. This list is not exhaustive of the factors that may affect any of the Company’s forward-looking statements.
Forward-looking statements are statements about the future and are inherently uncertain, and actual achievements of the Company or other
future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties,
and other factors, including without limitation those discussed under Part I, Item 1A. “Risk Factors” contained in our most
recent Annual Report on Form 10-K, and Part II, Item 1A. “Risk Factors” contained in our subsequent Quarterly Reports on Form
10-Q, as well as any amendments thereto, which are incorporated by reference into this prospectus and the applicable prospectus supplement
in their entirety, together with other information in this prospectus and the applicable prospectus supplement and the documents incorporated
by reference herein and therein. See the sections of this prospectus entitled “Where You Can Find More Information” and “Information
Incorporated by Reference.”
The Company’s
forward-looking statements contained in this prospectus are based on the beliefs, expectations, and opinions of management as of the date
of this prospectus. The Company does not assume any obligation to update forward-looking statements if circumstances or management’s
beliefs, expectations, or opinions should change, except as required by law. For the reasons set forth above, investors should not attribute
undue certainty to, or place undue reliance on, forward-looking statements.
Use of Proceeds
Unless the applicable
prospectus supplement states otherwise, we expect to use the net proceeds of the sale of the securities offered by this prospectus for
working capital and general corporate purposes, including to advance our efforts to launch construction of the Elk Creek Project and move
it to commercial operation.
As of the date of this prospectus,
we have not identified as probable any specific material proposed uses of these proceeds. If, as of the date of any prospectus supplement,
we have identified any such uses, we will describe them in the prospectus supplement. Pending any such uses, we may temporarily invest
the net proceeds.

entities that are fiscally transparent for United States federal income tax purposes (including limited liability companies) may not in
all circumstances be entitled to the benefits of the Convention. Members of or holders of an interest in such an entity that holds Common
Shares should consult their own tax advisers regarding the extent, if any, to which the benefits of the Convention will apply to the entity
in respect of its Common Shares.
Generally, a U.S. Resident
Holder’s Common Shares will be considered to be capital property of such holder provided that the U.S. Resident Holder is not a
trader or dealer in securities, did not acquire, hold, or dispose of the Common Shares in one or more transactions considered to be an
adventure or concern in the nature of trade (i.e., speculation), and does not hold the Common Shares in the course of carrying
on a business.
This
summary is based on the current provisions of the Canadian Tax Act and the Convention in effect as of the date prior to the date hereof,
all specific proposals to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance (Canada)
prior to the date hereof, and the current published administrative policies and assessing practices of the Canada Revenue Agency (the
“CRA”). It is assumed that all such amendments will be enacted as currently proposed, and that there will be no other material
change to any applicable law or administrative policy or assessing practice, whether by way of judicial, legislative or governmental decision
or action, although no assurance can be given in these respects. This summary is not exhaustive of all possible Canadian federal income
tax considerations. Except as otherwise expressly provided, this summary does not take into account any provincial, territorial, or foreign
tax considerations, which may differ materially from those set out herein.
This summary is
of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations, and is not intended to be and
should not be construed as legal or tax advice to any particular U.S. Resident Holder. U.S. Resident Holders are urged to consult their
own tax advisers for advice with respect to their particular circumstances. The discussion below is qualified accordingly.
Generally, a U.S. Resident
Holder’s Common Shares will not constitute “taxable Canadian property” of such holder at a particular time at which
the Common Shares are listed on a “designated stock exchange” (which currently includes Nasdaq) unless both of the following
conditions are concurrently met:
| (i) | at any time during the 60-month period that ends at the particular time, 25% or more of the issued shares of any class of the capital
stock of the Company were owned by or belonged to one or any combination of |
| (A) | the U.S. Resident Holder, |
| (B) | persons with whom the U.S. Resident Holder did not deal at arm’s length, and |
| (C) | partnerships in which the U.S. Resident Holder or a person referred to in clause (B) holds a membership interest directly or indirectly
through one or more partnerships, and |
| (ii) | at any time during the 60-month period that ends at the particular time, more than 50% of the fair market value of the Common Shares
was derived directly or indirectly from, one or any combination of, real or immovable property situated in Canada, “Canadian resource
properties” (as defined in the Canadian Tax Act), “timber resource properties” (as defined in the Canadian Tax Act),
or options in respect of, or interests in any of the foregoing, whether or not the property exists. |
Common Shares may also
be deemed to be “taxable Canadian property” in certain circumstances set out in the Canadian Tax Act.
A U.S. Resident Holder
who disposes or is deemed to dispose of one or more Common Shares generally should not thereby incur any liability for Canadian federal
income tax in respect of any capital gain arising as a consequence of the disposition.
A U.S. Resident Holder
to whom the Company pays or credits or is deemed to pay or credit a dividend on such holder’s Common Shares will be subject to Canadian
withholding tax, and the Company will be required to withhold the tax from the dividend and remit it to the CRA for the holder’s
account. The rate of withholding tax under the Canadian Tax Act is 25% of the gross amount of the dividend, but should generally be reduced
under the Convention to 15% (or, if the U.S. Resident Holder is a company which is the beneficial owner of at least 10% of the voting
stock of the Company, 5%) of the gross amount of the dividend. For this purpose, a company that is a resident of the United States for
purposes of the Canadian Tax Act and the Convention and is entitled to the benefits of the Convention shall be considered to own the voting
stock of the Company owned by an entity that is considered fiscally transparent under the laws of the United States and that is not a
resident of Canada, in proportion to such company’s ownership interest in that entity.
Competition Act
Limitations
on the ability to acquire and hold Common Shares may be imposed by the Competition Act (Canada). This legislation permits the Commissioner
of Competition of Canada (the “Commissioner”) to review any acquisition of a significant interest in the Company. This legislation
grants the Commissioner jurisdiction to challenge such an acquisition before the Canadian Competition Tribunal if the Commissioner believes
that it would, or would be likely to, result in a substantial lessening or prevention of competition in any market in Canada.
Investment Canada
Act
The Investment
Canada Act subjects an acquisition of control of a company by a non-Canadian to government review if the enterprise value of such company,
as calculated pursuant to the legislation, exceeds a threshold amount. A reviewable acquisition may not proceed unless the relevant minister
is satisfied that the investment is likely to result in a net benefit to Canada. Under the national-security-review regime in the Investment
Canada Act, review on a discretionary basis may also be undertaken by the federal government in respect of a broad range of investments
by a non-Canadian. No financial threshold applies to a national security review. The relevant test is whether such investment by a non-Canadian
could be “injurious to national security.”
NioCorp Assumed Warrants
In connection with the closing of the Transactions
(the “Closing”), pursuant to the Business Combination Agreement, the Company assumed the Warrant Agreement, dated as of March
17, 2021 (the “GXII Warrant Agreement”), by and between GXII and Continental Stock Transfer & Trust Company (“CST”),
as warrant agent, and each share purchase warrant of GXII thereunder (the “GXII Warrants”) that was issued and outstanding
immediately prior to March 17, 2023 was converted into one Warrant (the “NioCorp Assumed Warrants”) pursuant to the assignment,
assumption and amendment agreement to the GXII Warrant Agreement, dated March 17, 2023 (the GXII Warrant Agreement, as so amended, the
“NioCorp Assumed Warrant Agreement”), among NioCorp, GXII, CST, as existing warrant agent, and Computershare Inc. and its
affiliate Computershare Trust Company, N.A., together as successor warrant agent (the “NioCorp Assumed Warrant Agent”). In
connection with the Closing, NioCorp issued (a) 9,999,959 public NioCorp Assumed Warrants in respect of the GXII Warrants that were publicly
traded prior to the Closing and (b) 5,666,667 NioCorp Assumed Warrants to GX Sponsor II LLC (the “Sponsor”) in respect of
the GXII Warrants that it held prior to the Closing, which NioCorp Assumed Warrants were subsequently distributed by the Sponsor to its
members in connection with the Closing.
Both the public NioCorp Assumed Warrants and the NioCorp
Assumed Warrants issued to the Sponsor are subject to the terms of the NioCorp Assumed Warrant Agreement and are identical, with certain
exceptions applicable to the NioCorp Assumed Warrants issued to the Sponsor for so long as such NioCorp Assumed Warrants are held by the
Sponsor, its members, or their respective affiliates and other permitted transferees. In accordance with the NioCorp Assumed Warrant Agreement,
any NioCorp Assumed Warrants issued to the Sponsor that are held by someone other than the Sponsor, its members, or their respective affiliates
and other permitted transferees, are treated as public NioCorp Assumed Warrants.
Each NioCorp Assumed Warrant is exercisable on and
after April 16, 2023 until its expiration for 1.11829212 Common Shares at a price of $11.50 per 1.11829212 Common Shares (subject to adjustments
for stock splits, stock dividends, reorganizations, recapitalizations and the like). Under the terms of NioCorp Assumed Warrant Agreement,
for so long as the NioCorp Assumed Warrants issued to the Sponsor are held by the Sponsor, its members, or their respective affiliates
and other permitted transferees, such holders have the right to elect to exercise those NioCorp Assumed Warrants on a cashless basis.
For such NioCorp Assumed Warrants exercised on a cashless basis after the Closing, the holder will be entitled to pay the exercise price
for those NioCorp Assumed Warrants by surrendering all or portion of the cash and/or Common Shares (valued at their fair market value)
into which those NioCorp Assumed Warrants are exercisable as shall be elected by the holder. For this purpose, Common Shares so surrendered
will be deemed to have a “fair market value” equal to the average reported last sale price of the Common Shares for the 10
trading days ending on the third trading day prior to the date of exercise of the applicable NioCorp Assumed Warrants.
The NioCorp Assumed Warrants will expire at 5:00 p.m.,
New York City time, on March 17, 2028 or earlier upon redemption or liquidation.
The Company will not be obligated to deliver any
Common Shares pursuant to the exercise of a NioCorp Assumed Warrant and will have no obligation to settle such exercise unless a registration
statement under the Securities Act with respect to the Common Shares underlying the NioCorp Assumed Warrants is then effective and a
prospectus relating thereto is current, subject to the Company satisfying its obligations described below with respect to registration.
No NioCorp Assumed Warrant will be exercisable and the Company will not be obligated to issue Common Shares upon exercise of a NioCorp
Assumed Warrant unless Common Shares issuable upon such exercise have been registered, qualified or deemed to be exempt under the securities
laws of the state of residence of the registered holder of the NioCorp Assumed Warrants. In the event that the conditions in the two
immediately preceding sentences are not satisfied with respect to a NioCorp Assumed Warrant, the holder of such NioCorp Assumed Warrant
will not be entitled to exercise such NioCorp Assumed Warrant and such NioCorp Assumed Warrant may have no value and expire worthless.
In no event will the Company be required to net cash settle any NioCorp Assumed Warrant.
The NioCorp Assumed Warrants, and the underlying
Common Shares issuable upon the exercise thereof, were registered under the Securities Act pursuant to the Company’s registration
statement on Form S-4, originally filed on November 7, 2022, as subsequently amended, which was declared effective by the SEC on February
8, 2023. The ongoing registered offering of the Common Shares underlying the NioCorp Assumed Warrants is being conducted pursuant to the
Company’s registration statement on Form S-3, originally filed on April 14, 2023, as subsequently post-effectively amended to convert
such registration statement to Form S-1, which was declared effective on October 30, 2023.
The Company will have the right to call the public
NioCorp Assumed Warrants for redemption at any time following the Closing Date:
| · | in whole and not in part; |
| · | at a price of $0.01 per NioCorp Assumed Warrant; |
| · | upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”)
to each public NioCorp Assumed Warrant holder; |
| · | if, and only if, the reported last sale price of the Common Shares equals or exceeds approximately $16.10
per share (subject to certain adjustments) for any 20 trading days within a 30-trading day period commencing once the NioCorp Assumed
Warrants become exercisable and ending three business days before the Company sends the notice of redemption to the public NioCorp Assumed
Warrant holders; and |
| · | if there is an effective registration statement covering the Common Shares issuable upon exercise of
the NioCorp Assumed Warrants, and a current prospectus relating thereto, available throughout the 30-day redemption period. |
The NioCorp Assumed Warrants issued to the Sponsor
are not redeemable by the Company for so long as such NioCorp Assumed Warrants are held by the Sponsor, its members, or their respective
affiliates or other permitted transferees. In addition, the Company may not exercise its redemption right if the issuance of Common Shares
upon exercise of the NioCorp Assumed Warrants is not exempt from registration or qualification under applicable state blue sky laws or
the Company is unable to effect such registration or qualification.
If the Company calls the public NioCorp Assumed Warrants
for redemption as described above, the Company will have the option to require any holder that wishes to exercise its public NioCorp
Assumed Warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their public NioCorp
Assumed Warrants on a “cashless basis,” the Company will consider, among other factors, its cash position, the number of
NioCorp Assumed Warrants that are outstanding and the dilutive effect on the Company’s shareholders of issuing the maximum number
of Common Shares issuable upon the exercise of the NioCorp Assumed Warrants. If the Company takes advantage of this option, all holders
of public NioCorp Assumed Warrants would pay the exercise price by surrendering their NioCorp Assumed Warrants for that number of Common
Shares equal to the quotient obtained by dividing (x) the product of the number of Common Shares underlying the public NioCorp Assumed
Warrants, multiplied by the difference between the exercise price of the NioCorp Assumed Warrants and the “fair market value”
(defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of
the Common Shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent
to the holders of public NioCorp Assumed Warrants. If the Company takes advantage of this option, the notice of redemption will contain
the information necessary to calculate the number of Common Shares to be received upon exercise of the NioCorp Assumed Warrants, including
the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of Common Shares
to be issued and thereby lessen the dilutive effect of a redemption of the public NioCorp Assumed Warrants. If the Company calls the
public NioCorp Assumed Warrants for redemption and does not take advantage of this option, the Sponsor, its members, and their respective
affiliates and other permitted transferees would still be entitled to exercise their NioCorp Assumed Warrants for cash or on a cashless
basis using the same formula described above that other NioCorp Assumed Warrant holders would have been required to use had all NioCorp
Assumed Warrant holders been required to exercise their NioCorp Assumed Warrants on a cashless basis, as described in more detail below.
A holder of a NioCorp Assumed Warrant may notify the
Company in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such NioCorp
Assumed Warrant, to the extent that after giving effect to such exercise, such holder (together with such holder’s affiliates),
to the NioCorp Assumed Warrant Agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount
as a holder may specify) of the Common Shares outstanding immediately after giving effect to such exercise.
The NioCorp Assumed Warrants have certain anti-dilution
and adjustments rights upon certain events.
The NioCorp Assumed Warrants may be exercised upon
surrender of the certificate representing such NioCorp Assumed Warrants on or prior to the expiration date at the offices of the NioCorp
Assumed Warrant Agent, with the exercise form on the reverse side of such certificate completed and executed as indicated, accompanied
by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to the order
of the NioCorp Assumed Warrant Agent or by wire transfer, for the number of NioCorp Assumed Warrants being exercised. The NioCorp Assumed
Warrant holders will not have the rights or privileges of holders of Common Shares or any attendant voting rights until they exercise
their NioCorp Assumed Warrants and receive Common Shares. After the issuance of Common Shares upon exercise of the NioCorp Assumed Warrants,
each holder will be entitled to one (1) vote for each Common Share held of record on all matters to be voted on by NioCorp shareholders.
If, upon exercise of the NioCorp Assumed Warrants,
a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round down to the nearest whole
number of Common Shares to be issued to the NioCorp Assumed Warrant holder.
The NioCorp Assumed Warrants were issued in registered
form under the NioCorp Assumed Warrant Agreement. The NioCorp Assumed Warrant Agreement may be amended by the parties thereto without
the consent of any registered holder (i) for the purpose of curing any ambiguity, or curing, correcting or supplementing any mistake,
or adding or changing any other provisions with respect to matters or questions arising under NioCorp Assumed Warrant Agreement as the
parties may deem necessary or desirable and that the parties deem shall not adversely affect the interest of the registered holders of
the NioCorp Assumed Warrants, and (ii) to provide for the delivery of such kind and amount of Common Shares or other securities or property
(including cash) receivable upon a reclassification, reorganization, merger or consolidation, or upon a dissolution following any such
sale or transfer, that the holder of NioCorp Assumed Warrants would have received if such holder had exercised his, her or its NioCorp
Assumed Warrants immediately prior to such event. All other modifications or amendments, including any amendment to increase the warrant
price or shorten the exercise period, shall require the vote or written consent of the registered holders of a majority of the then outstanding
public NioCorp Assumed Warrants. Any amendment solely to the NioCorp Assumed Warrants issued to the Sponsor and that are held by the Sponsor,
its members, or their respective affiliates or other permitted transferees, shall require the vote or written consent of a majority of
the holders of the then outstanding NioCorp Assumed Warrants issued to the Sponsor.
Convertible Debentures
On January 26, 2023, NioCorp entered into the Securities
Purchase Agreement (the “Yorkville Convertible Debt Financing Agreement”) with YA. Pursuant to the Yorkville Convertible Debt
Financing Agreement, YA advanced a total amount of $15,360,000 to NioCorp in consideration of the issuance by NioCorp to YA of $16,000,000
aggregate principal amount of convertible debentures (the “Convertible Debentures”) at the time of Closing (the “Debenture
Closing”). As of June 12, 2024, there was $550,000 aggregate principal amount of the Convertible Debentures outstanding.
Each Convertible Debenture issued under the Yorkville
Convertible Debt Financing Agreement is an unsecured obligation of NioCorp, matures on September 17, 2024, which maturity may be extended
for one six-month period in certain circumstances at the option of NioCorp, and incurs a simple interest rate obligation of 5.0% per
annum (which will increase to 15.0% per annum upon the occurrence of an event of default). The outstanding principal amount of, accrued
and unpaid interest, if any, on, and premium, if any, on the Convertible Debentures must be paid by NioCorp in cash when the same becomes
due and payable under the terms of the Convertible Debentures at their stated maturity, upon their redemption or otherwise.
Subject to certain limitations contained within the
Yorkville Convertible Debt Financing Agreement and the Convertible Debentures, including those as described below, holders of the Convertible
Debentures will be entitled to convert the principal amount of, and accrued and unpaid interest, if any, on each Convertible Debenture,
in whole or in part, from time to time over their term, into a number of Common Shares equal to the quotient of the principal amount and
accrued and unpaid interest, if any, being converted divided by the Conversion Price. The “Conversion Price” means, as of
any Conversion Date (as defined below) or other date of determination, the greater of (i) 90% of the average of the daily U.S. dollar
volume-weighted average price of the Common Shares on the principal U.S. market for the Common Shares as reported by Bloomberg Financial
Markets during the five consecutive trading days immediately preceding the date on which the holder exercises its conversion right in
accordance with the requirements of the Yorkville Convertible Debt Financing Agreement (the “Conversion Date”) or other date
of determination, but not lower than the Floor Price (as defined below), and (ii) the five-day volume-weighted average price of the Common
Shares on the TSX (or on the principal U.S. market if the majority of the trading volume and value of the Common Shares occurred on Nasdaq
during the relevant period) for the five consecutive trading days immediately prior to the Conversion Date or other date of determination
less the maximum applicable discount allowed by the TSX. The “Floor Price” means a price of $2.1435 per share, which is equal
to the lesser of (a) 30% of the average of the daily volume-weighted average price of the Common Shares on the principal U.S. market for
the Common Shares as reported by Bloomberg Financial Markets during the five consecutive trading days immediately preceding the Debenture
Closing and (b) 30% of the average of the volume-weighted average price of the Common Shares on the principal U.S. market for the Common
Shares as reported by Bloomberg Financial Markets during the five consecutive trading days immediately following the Debenture Closing,
subject to certain adjustments to give effect to any stock dividend, stock split, reverse stock split, recapitalization or similar event.
The terms of the Convertible Debentures restrict the
number of Convertible Debentures that may be converted during each calendar month by YA at a Conversion Price below a fixed price equal
to approximately $8.9422 (i.e., the quotient of $10.00 divided by 1.11829212 (being the number of Common Shares that were exchanged for
each share of GXII at the Closing, after giving effect to the reverse stock split at a ratio of 10-for-1 effectuated by each of NioCorp
and ECRC on the date of Closing (the “Reverse Stock Split”))), subject to adjustment to give effect to any stock dividend,
stock split, reverse stock split, recapitalization or similar event. The Convertible Debentures are subject to customary anti-dilution
adjustments.
The terms of the Convertible Debentures restrict the
conversion of Convertible Debentures by YA if such a conversion would cause YA to exceed certain beneficial ownership thresholds in NioCorp
or such a conversion would cause the aggregate number of Common Shares issued pursuant to the Yorkville Convertible Debt Financing Agreement
to exceed the thresholds for issuance of Common Shares under the rules of Nasdaq, unless prior shareholder approval is obtained.
Financing Warrants
In conjunction with the Debenture Closing, NioCorp
issued to YA pursuant to the Yorkville Convertible Debt Financing Agreement financing warrants (the “Financing Warrants”)
to purchase 1,789,267 Common Shares, which is equal to the quotient of the principal amount of Convertible Debentures issued in such Debenture
Closing divided by the “Exercise Price,” which is equal to approximately $8.9422 (i.e., the quotient of $10.00 divided by
1.11829212 (being the number of Common Shares that were exchanged for each share of GXII at the Closing, after giving effect to the reverse
stock split at a ratio of 10-for-1 effectuated by each of NioCorp and ECRC on the Closing Date)), in each case, subject to adjustment
to give effect to any stock dividend, stock split, reverse stock split, recapitalization or similar event.
The Financing Warrants are exercisable, in whole or
in part, but not in increments of less than $50,000 aggregate Exercise Price (unless the remaining aggregate Exercise Price is less than
$50,000), beginning on May 4, 2023 and may be exercised at any time prior to their expiration. Holders of the Financing Warrants may exercise
their Financing Warrants, at their election, by paying the Exercise Price in cash or, if at any time there is no effective registration
statement registering, or no current prospectus available for, the resale of the underlying Common Shares, on a cashless exercise basis.
On each of the first 12 monthly anniversaries of September 17, 2023, 1/12th of the Financing Warrants will expire.
The Financing Warrants have customary anti-dilution
adjustments to be determined in accordance with the requirements of the applicable stock exchanges.
The terms of the Financing Warrants restrict the exercise
of Financing Warrants by YA if such an exercise would cause YA to exceed certain beneficial ownership thresholds in NioCorp or such an
exercise would cause the aggregate number of Common Shares issued pursuant to the Yorkville Convertible Debt Financing Agreement to exceed
the thresholds for issuance of Common Shares under the rules of Nasdaq, unless prior shareholder approval is obtained.
Notes
On April 12, 2024, the Company issued and sold to
the YA and Lind Global Fund II LP (“Lind”), in a private placement (the “April 2024 Private Placement”), $8.0
million aggregate principal amount of unsecured notes (the “Notes”), pursuant to a Securities Purchase Agreement, dated April
11, 2024 (the “Purchase Agreement”), between the Company and each of YA and Lind, as purchasers (in such capacity, the “Purchasers”).
Pursuant to the terms of the Notes, subject to certain exceptions as described below, on the first day of each calendar month, beginning
on June 1, 2024 (excluding August 2024) (a “Payment Date”), the Company will be required to repay a portion of the outstanding
balance of all of the Notes, on a pro-rata basis, in an amount equal to the sum of (i) $1.4 million of principal (or the outstanding principal
if less than such amount) in the aggregate among all of the outstanding Notes, plus (ii) 8.0% of the principal amount being paid (the
“Payment Premium”), and (iii) accrued and unpaid interest, if any, as of the Payment Date. The Company is required to make
payments on each Payment Date until the entire outstanding principal is repaid, but will not have an obligation to make a payment on a
Payment Date if the Equity Conditions (as defined below) are satisfied.
Pursuant to the Purchase Agreement, the Purchasers
advanced an aggregate of $6.96 million to NioCorp in consideration of the issuance by NioCorp to the Purchasers of $8.0 million aggregate
principal amount of Notes and Warrants (the “April 2024 Warrants”) to purchase up to 615,385 Common Shares (the “April
2024 Warrant Shares”). Each April 2024 Warrant is exercisable for one Common Share for cash or, if at any time there is no effective
registration statement registering, or no current prospectus available for, the resale of the underlying Common Shares, on a cashless
basis at the option of the holder, at a price per Common Share of $3.25 (the “April 2024 Exercise Price”), subject to adjustment
for recapitalizations, stock splits, reverse stock splits or similar events, and expires April 12, 2027.
Subject to certain limitations, including those as
described below, contained within the Notes, holders of the Notes will be entitled to convert the principal amount of, accrued and unpaid
interest, if any, and any Payment Premium that has become due and payable on each Note, from time to time over their term, into a number
of Common Shares equal to the quotient of the amount being converted divided by the fixed conversion price of $2.75 per Common Share (the
“Fixed Conversion Price”) up to a maximum of 3,141,817 Common Shares (together with the April 2024 Warrant Shares, the “Underlying
Shares”). The terms of the Notes restrict the conversion of the Notes by a holder if such a conversion or exercise would cause such
holder to exceed certain beneficial ownership thresholds in NioCorp.
The Notes are the unsecured obligations of NioCorp
and will mature on December 31, 2024. The Notes will incur a simple interest rate obligation of 0.0% per annum (which will increase to
18.0% per annum upon the occurrence of an event of default). The outstanding principal amount of, accrued and unpaid interest, if any,
on, and the Payment Premium, if any, on the Notes must be paid by NioCorp in cash when the same becomes due and payable under the terms
of the Notes at their stated maturity, upon their redemption or otherwise.
As mentioned above, NioCorp is required to make payments
on each Payment Date until the entire outstanding principal is repaid, but will not have an obligation to make a payment on a Payment
Date if the Equity Conditions are satisfied. The “Equity Conditions” means (i) on each of the five consecutive trading days
prior a Payment Date (the “Measuring Period”) a registration statement registering the resale by the Purchasers of the Underlying
Shares under the Securities Act (the “Underlying Shares Registration Statement”) is effective and available for the resale
by the Purchasers of all Underlying Shares, (ii) NioCorp has no knowledge of any fact that would cause the Underlying Shares Registration
Statement not to be effective and available for the resale of the Underlying Shares, (iii) on each day during the Measuring Period, the
Common Shares are designated for quotation on Nasdaq, or on such other market or exchange on which the Common Shares are then listed or
traded to the extent such other market or exchange is the principal U.S. trading market for the Common Shares (the “Principal U.S.
Market”), and have not been suspended from trading nor have delisting or suspension of trading been threatened or pending, (iv)
during the Measuring Period, an event of default has not occurred, (v) on each trading day during the Measuring Period, the daily U.S.
dollar volume-weighted average price for a Common Share on the Principal U.S. Market as reported by Bloomberg Financial Markets is greater
than 120% of the Fixed Conversion Price, (vi) on each trading day during the Measuring Period the average daily volume traded exceeded
$500,000, and (vii) there is no limitation on conversion under the terms of Notes. In addition, any Payment Date and the amount payable
to the holder of a Note on any such Payment Date may be modified from time to time upon mutual written consent of NioCorp and such holder.
Pursuant to the terms of the Notes, to the extent
a holder is a party to Yorkville Equity Facility Financing Agreement, for so long as any amount remains outstanding under such holder’s
Note, the amount of cash received by the Company as payment from such holder in respect of an Advance (as defined in the Yorkville Equity
Facility Financing Agreement) is subject to a right of offset, exercisable in such holder’s sole discretion, against an equal amount
of principal, accrued and unpaid interest, if any, and other amounts that have become due and payable under the Note, not to exceed $1.512
million in any calendar month.
The Notes may also be redeemed at NioCorp’s
option at any time and from time to time over their term at a redemption price equal to the principal amount being redeemed, plus the
Payment Premium, plus accrued and unpaid interest, if any, as of the redemption date.
The Notes contain events of default customary for
instruments of their type (with customary grace periods, as applicable) and provide that, upon the occurrence of an event of default arising
from certain events of bankruptcy or insolvency with respect to NioCorp, all outstanding Notes will become due and payable immediately
without further action or notice. If any other type of event of default occurs and is continuing, then any holder may declare all of its
Notes to be due and payable immediately.
Pursuant to a global guaranty agreement, dated as
of April 11, 2024, among ECRC and 0896800 B.C. Ltd. (together with ECRC, the “Guarantors”), the Guarantors guaranteed the
full, prompt and unconditional payment when due (whether at maturity, by acceleration or otherwise), and the performance of all liabilities,
agreements and other obligations of NioCorp to the Purchasers contained in the Notes and the Purchase Agreement, to the extent such liabilities,
agreements and obligations are payable in cash.
April 2024 Warrants
On April 12, 2024, in connection with the closing
of the April 2024 Private Placement, the Company issued to the Purchasers, in proportion to the aggregate principal amount of Notes issued
to each Purchaser, April 2024 Warrants to purchase the April 2024 Warrant Shares, which is equal to 25% of the aggregate principal amount
of Notes issued to the Purchasers divided by the April 2024 Exercise Price, subject to any adjustment to give effect to any stock dividend,
stock split or recapitalization.
The terms of the April 2024 Warrants restrict the
exercise of the April 2024 Warrants by a holder if such an exercise would cause such holder to exceed certain beneficial ownership thresholds
in NioCorp.
The April 2024 Warrants will be exercisable, in
whole or in part, but not in increments of less than $50,000 aggregate April 2024 Exercise Price (unless the remaining aggregate
April 2024 Exercise Price is less than $50,000), at any time on or before April 12, 2027. Holders of the April 2024 Warrants may
exercise their April 2024 Warrants, at their election, by paying the April 2024 Exercise Price in cash or on a cashless exercise
basis, if at any time there is no effective registration statement or prospectus available for the resale of the underlying Common
Shares or an event of default under the Notes has occurred and is continuing.
The April 2024 Warrants are subject to adjustment
for any stock dividend or other distribution, stock split, reverse stock split or recapitalization
Description of Warrants
General
The following description,
together with the additional information we may include in any applicable prospectus supplement, summarizes the material terms and provisions
of the Warrants that we may offer under this prospectus. While the terms we have summarized below will apply generally to any Warrants
that we may offer under this prospectus, we will describe the particular terms of any series of Warrants in more detail in the applicable
prospectus supplement. The terms of any Warrants offered under a prospectus supplement may differ from the terms described below.
We will file as exhibits
to the registration statement of which this prospectus is a part, or will incorporate by reference from another report that we file with
the SEC, the form of Warrant agreement or Warrant indenture, which may include a form of Warrant certificate, that describes the terms
of the particular series of Warrants we are offering before the issuance of the related series of Warrants. The following summary of material
provisions of the Warrants and the Warrant agreements and the Warrant indentures are subject to, and qualified in their entirety by reference
to, all the provisions of the Warrant agreement or Warrant indenture, and Warrant certificate, applicable to a particular series of Warrants.
We urge you to read the applicable prospectus supplement related to the particular series of Warrants that we sell under this prospectus,
as well as the complete Warrant agreements, Warrant indentures and Warrant certificates that contain the terms of the Warrants.
We will describe in the
applicable prospectus supplement the terms relating to Warrants being offered including:
| · | the offering price and aggregate number of Warrants offered; |
| · | if applicable, the number of Warrants issued with each Common Share being
issued; |
| · | if applicable, the date on and after which the Warrants and the related
Common Shares will be separately transferable; |
| · | the number of Common Shares purchasable upon exercise of one Warrant and
the price at which these Common Shares may be purchased upon such exercise; |
| · | the terms of any rights to redeem or call the Warrants; |
| · | any provisions for changes to or adjustments in the exercise price or number
of Common Shares issuable upon exercise of the Warrants; |
| · | the dates on which the right to exercise the Warrants will commence and
expire; |
| · | the manner in which the Warrant agreements, Warrant indentures and Warrants
may be modified; |
| · | federal income tax consequences of holding or exercising the Warrants, if
material; and |
| · | any other specific terms, preferences, rights or limitations of or restrictions
on the Warrants. |
Before exercising their
Warrants, holders of Warrants will not have any of the rights of holders of the Common Shares purchasable upon such exercise, including
the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up of our affairs or to exercise voting
rights, if any.
Exercise of Warrants
Unless we otherwise specify
in the applicable prospectus supplement, each Warrant will entitle the holder to purchase one Common Share at the exercise price that
we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the
Warrants may exercise the Warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus
supplement, and after the close of business on the expiration date, unexercised Warrants will become void.
Holders of the Warrants
may exercise the Warrants by delivering the Warrant certificate representing the Warrants to be exercised together with specified information,
and paying the required amount to the Warrant agent in immediately available funds, as provided in the applicable prospectus supplement.
We intend to set forth in any Warrant agreement or Warrant indenture and in the applicable prospectus supplement the information that
the holder of the Warrant will be required to deliver to the Warrant agent.
Upon receipt of the required
payment and any Warrant certificate or other form required for exercise properly completed and duly executed at the corporate trust office
of the Warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the Common Shares
purchasable upon such exercise. If fewer than all of the Warrants represented by the Warrant or Warrant certificate are exercised, then
we will issue a new Warrant or Warrant certificate for the remaining amount of Warrants. If we so indicate in the applicable prospectus
supplement, holders of the Warrants may surrender securities as all or part of the exercise price for Warrants.
Description of Units
As specified in the applicable
prospectus supplement, we may issue units consisting of one or more of the following: Common Shares, Warrants or any combination of such
securities. The applicable prospectus supplement will describe:
| · | the terms of the units and of any of our Common Shares or Warrants comprising
the units, including whether and under what circumstances the securities comprising the units may be traded separately; |
| · | a description of the terms of any unit agreement governing the units; |
| · | a description of the provisions for the payment, settlement, transfer or
exchange of the units; and |
| · | if applicable, a discussion of any material federal income tax considerations. |
Plan of Distribution
We
may sell the securities from time to time in one or more transactions:
| · | through one or more underwriters or dealers; |
| · | directly to purchasers, including our existing shareholders in a rights
offering; |
| · | through a combination of any of these methods of sale. |
We may distribute the
securities from time to time in one or more transactions at:
| · | a fixed price or prices, which may be changed from time to time; |
| · | market prices prevailing at the time of sale; |
| · | prices related to prevailing market prices; or |
We will describe the method
of distribution of each series of securities in the applicable prospectus supplement.
We may determine the price
or other terms of the securities offered under this prospectus by use of an electronic auction. We will describe how any auction will
determine the price or any other terms, how potential investors may participate in the auction and the nature of the underwriters’
obligations in the related supplement to this prospectus.
Underwriters, dealers
or agents may receive compensation in the form of discounts, concessions or commissions from us or our purchasers as their agents in connection
with the sale of the securities. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act.
As a result, discounts, commissions or profits on resale received by underwriters, dealers or agents may be treated as underwriting discounts
and commissions. Each prospectus supplement will identify any underwriter, dealer or agent, and describe any compensation received by
them from us. We may grant underwriters who participate in the distribution of securities an option to purchase additional securities
to cover over-allotments, if any, in connection with the distribution.
We may have agreements
with the underwriters, dealers and agents to indemnify them against specified civil liabilities, including liabilities under the Securities
Act. Underwriters, dealers and agents may engage in transactions with or perform services for us in the ordinary course of their businesses.
To the extent required,
this prospectus may be amended and supplemented from time to time to describe a specific plan of distribution.
Agents
We may designate agents
who agree to use their reasonable efforts to solicit purchases of our securities for the period of their appointment or to sell our securities
on a continuing basis.
Underwriters
If we use underwriters
for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities
in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the
time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable
underwriting agreement. The underwriters will be obligated to purchase all the securities of the series offered if they purchase any
of the securities of that series. We may change from time to time any initial public offering price and any discounts or concessions
the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship. We will describe
the nature of any such relationship in any prospectus supplement naming any such underwriter.
Direct Sales
We may also sell securities
directly to one or more purchasers without using underwriters or agents. Underwriters, dealers and agents that participate in the distribution
of the securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive from us and any
profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify
in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation.
Trading Markets and
Listing of Securities
Unless otherwise specified
in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other
than our Common Shares, which are listed on The Nasdaq Global Market. We may elect to list any other class or series of securities on
any exchange or market, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or
series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice.
We cannot give any assurance as to the liquidity of the trading market for any of the securities.
Stabilization Activities
Any underwriter may engage
in over-allotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange
Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids
to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve
purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters
to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction
to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced,
the underwriters may discontinue any of these activities at any time.
Delayed Delivery Contracts
If we so indicate in the
prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase
securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery
on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The
prospectus supplement will describe the commission payable for solicitation of those contracts.
Legal Matters
The validity of the securities
in respect of which this prospectus is being delivered will be passed upon for us by Blake, Cassels & Graydon LLP, Vancouver, British
Columbia, Canada, relating to matters of British Columbia or Canadian law, and Jones Day, relating to matters of New York or U.S. federal
law. Additional legal matters may be passed upon for us or any underwriters, dealers or agents by counsel that we will name in the applicable
prospectus supplement.
