DESIGNATED NEWS RELEASE
VANCOUVER, BC, Jan. 23,
2023 /PRNewswire/ - GoldMining Inc. (the
"Company" or "GoldMining") (TSX: GOLD) (NYSE
American: GLDG) is pleased to announce an updated Mineral
Resource estimate ("MRE") on its 100% owned La Mina Project
located in the Middle Cauca Porphyry Belt, Antioquia,
Colombia. The MRE includes a maiden resource estimate on the
La Garrucha deposit which incorporates drilling completed by the
Company in 2022.
Highlights:
La Garrucha – New Discovery
- Indicated Mineral Resources of 0.20 million ounces (Moz) gold
equivalent (AuEq) at 0.84 g/t AuEq (7.4 million tonnes (Mt) grading
0.65 g/t gold, 3.14 g/t silver and 0.11% copper) (see Table 1);
and
- Inferred Mineral Resources of 1.02 Moz AuEq at 0.72 g/t AuEq
(44.1 Mt grading 0.55 g/t gold, 2.46 g/t silver and 0.10% copper)
(see Table 1).
La Mina –
Combined MRE
- Indicated Mineral Resources of 1.15 Moz AuEq at 1.06 g/t AuEq,
an increase of 16% in ounces and decrease in grade of 3% from 2022
(33.8 Mt grading 0.73 g/t gold, 2.08 g/t silver and 0.21% copper)
(see Table 1); and
- Inferred Mineral Resources of 1.45 Moz AuEq at 0.80 g/t AuEq an
increase of 215% in ounces and decrease in grade of 24% from 2022
(56.2 Mt grading 0.58 g/t gold, 2.32 g/t silver and 0.14% copper)
(see Table 1).
Alastair Still, CEO of
GoldMining, commented, "We are extremely pleased that the Company's
first exploration drilling program at La Mina has identified a
significant discovery at the La Garrucha deposit that has added
over 1,000,000 gold equivalent ounces of estimated Inferred
Resources and 200,000 gold equivalent ounces of estimated Indicated
Resources to an already robust Mineral Resource estimate on our La
Mina project. This exciting discovery has exceeded our expectations
and builds upon the positive economics set out in our 2022
Preliminary Economic Assessment, which was based on the prior
resource estimate for the project, exclusive of La Garrucha.
Throughout, our team has maintained high standards of sustainable
exploration and demonstrated our commitment to safety, effective
stakeholder engagement and environmental stewardship.
With all-inclusive direct drilling costs by the Company at La
Garrucha of under US$1.2 million for
our recent program, this discovery was made at a very efficient
cost per ounce of estimated resource and exemplifies our strategy
and progress of unlocking value from our portfolio of gold and
gold-copper assets while maintaining a peer-leading balance
sheet."
Tim Smith, Vice President
Exploration of GoldMining, commented, "The updated Mineral Resource
estimate at La Garrucha represents an unqualified success for the
Company in applying its strategy of identifying the best value
accretion opportunities within our diverse portfolio of gold and
gold-copper resource assets located throughout the Americas.
From inception to execution, the drill program was expertly managed
by our team in Colombia and the
results demonstrate both the quality and further potential for
additional discovery within the La Mina porphyry gold-copper
mineral system. On the strength of this updated Mineral
Resource estimate, the Company now looks forward to updating the La
Mina Preliminary Economic Assessment (PEA) which we expect to
complete on or around mid-2023."
La Mina Updated Resource Metrics:
- Indicated Mineral Resource tonnage has increased by 19.5% from
the prior estimate, while metal content for gold, silver and copper
has increased by 19.7%, 40.7% and 5.9%, respectively compared to
the prior resource estimate (see Table 2);
- Inferred Mineral Resource tonnage has increased 312.5%, while
metal content for gold, silver and copper has increased by 265.6%,
442.5%, and 111.0%, respectively compared to the prior resource
estimate (see Table 2);
- The MRE has been updated with metal prices of US$1,700/oz gold, US$21/oz silver, and US$3.50/lb copper, compared to the prior estimate
which used metal prices of US$1,600/oz gold, US$21/oz silver, and US$3.25/lb copper;
- The MRE utilizes pit shells to constrain resources at the La
Cantera, La Garrucha and Middle Zone deposits using a 0.30 g/t Au
cut-off grade, compared to the prior estimate which used 0.25 g/t
Au cut-off grade;
- Metallurgical work has been conducted for the La Garrucha
deposit by ALS in Kamloops, British
Columbia from a 100 kg bulk sample collected from drill
core;
- The total La Mina Project area comprises a database of
111 drill holes totaling 40,179 metres with 102 drillholes and
37,256 metres drilled within the three deposits at La Cantera, La
Garrucha and Middle Zone; and
- For the first time, the MRE at La Mina incorporates the La
Garrucha deposit which is located within 1 kilometre to the east of
the prior mineral resources. Refer to Figure 1.

1. The Mineral
Resource for La Mina is an in-pit constrained resource calculated
using a Whittle-Pit algorithm with "reasonable prospects of
eventual economic extraction" using the following
assumptions:
- Metal prices of
US$1,700/oz Au, US$21/oz Ag and US$3.50/lb Cu;
- Royalty of
6% NSR, inclusive of government
royalties;
- Pit slopes are 50
degrees; and
- Mining, processing
and G&A costs were used to calculate cut-off of 0.30
g/t Au.
|
2. Metallurgical
recoveries are: 82% for Au, 84% for Cu, and 30% for Ag.
|
3.
Gold-equivalent grades were calculated using the following formula:
AuEq = Au (g/t) + [Cu(%) x {Cu Price/Au Price} x 22.0462 x 31.1035]
+ [Ag (g/t) x {Ag Price/Au Price}].
|
4. Mineral
resources are classified as Indicated Resources and Inferred
Resources and are based on the 2014 CIM Definition Standards on
Mineral Resources and Mineral Reserves.
|
5. Mineral
Resources, which are not Mineral Reserves, do not have demonstrated
economic viability. There is no certainty that all or any part of
the Mineral Resources will be converted to Mineral Reserves. The
estimate of mineral resources may be materially affected by
environmental permitting, legal, title, taxation, sociopolitical,
marketing or other relevant issues.
|
6. Numbers may
not add due to rounding.

The La Mina property consists of two concession contracts and
two concession contract applications covering 3,210 hectares
located in the Department of Antioquia, Republic of Colombia, some 51 km SW of Medellin. The MRE for La Mina incorporates the
La Cantera, La Garrucha and Middle Zone porphyry deposits located
within 1 km of each other.
From late March to mid-August
2022, GoldMining completed a diamond core drilling program
comprising five drill holes for 3,485
m at the La Garrucha deposit, a porphyry mineral system
which measures over 400 m in strike
length by 300 m in width and to at
least 775 m below surface where it
remains open. Gold and copper mineralization in the La Garrucha
porphyry intrusive complex is accompanied by strong potassic
alteration, characterized by secondary potassium feldspar and
biotite, disseminated and vein magnetite, quartz stockwork veining
and both vein-hosted and disseminated sulphides that include
pyrite, chalcopyrite and lesser bornite. Lithological, alteration
and structural logging of both the new core and re-logging of
historic core was completed to compile a three-dimensional
geological model.
The MRE disclosed herein for the La Mina Project was prepared by
Scott Wilson, C.P.G., of Resource
Development Associates Inc. and has an effective date of
December 20, 2022. The MRE
updates and replaces the prior MRE of the Company contained in its
technical report titled, "NI 43-101 Technical Report and
Preliminary Economic Assessment: GoldMining Inc., La Mina Project,
Antioquia, Republic of Colombia"
dated effective January 12, 2022.
GoldMining will file a technical report for the MRE updates at
La Mina in due course.

Notice to Readers
Disclosure regarding Mineral Resource estimates included
herein have been prepared by the Company in accordance with NI
43-101. NI 43-101 is a rule developed by the Canadian Securities
Administrators that establishes standards for public disclosure by
issuer of scientific and technical information concerning mineral
projects. NI 43-101 differs significantly from the disclosure
requirements of the United States Securities and Exchange
Commission ("SEC") generally applicable to U.S. companies subject
to the SEC's disclosure requirements. For example, the terms
"Indicated Mineral Resource" and "Inferred Mineral Resource" are
defined in NI 43-101 by reference to the guidelines set out in the
CIM Definition Standards on Mineral Resources and Mineral Reserves.
Shareholders resident in the United
States are cautioned that while terms are substantially
similar to "indicated mineral resources" and "inferred mineral
resources" as defined by the SEC, there are differences in the
definitions and standards under applicable SEC Rules and NI 43-101.
Accordingly, there is no assurance any mineral resources that the
Company may report as "Indicated Mineral Resources" and "Inferred
Mineral Resources" under NI 43-101 will be the same as the reserve
or resource estimates prepared under rules applicable to
United States domestic issuers.
Investors are cautioned not to assume that any part or all of
mineral resources will ever be converted into reserves. Pursuant to
CIM Definition Standards, "Inferred mineral resources" are that
part of a mineral resource for which quantity and grade or quality
are estimated on the basis of limited geological evidence and
sampling. Such geological evidence is sufficient to imply but not
verify geological and grade or quality continuity. An inferred
mineral resource has a lower level of confidence than that applying
to an indicated mineral resource and must not be converted to a
mineral reserve. However, it is reasonably expected that the
majority of inferred mineral resources could be upgraded to
indicated mineral resources with continued exploration. Under
Canadian rules, estimates of inferred mineral resources may not
form the basis of feasibility or pre-feasibility studies, except in
rare cases. Investors are cautioned not to assume that all or any
part of an inferred mineral resource is economically or legally
mineable. Disclosure of "contained ounces" in a resource is
permitted disclosure under Canadian regulations; however, the SEC
normally only permits issuers to report mineralization that does
not constitute "reserves" by SEC standards as in place tonnage and
grade without reference to unit measures.
Forward-looking
Statements
This document contains certain forward-looking statements
that reflect the current views and/or expectations of GoldMining
