RISK FACTORS

In deciding whether to exchange Initial Notes for New Notes, you should carefully consider the risks described below, as well as the information included or incorporated by reference in this prospectus. In addition, please read “Notice Regarding Presentation of Mineral Reserve and Mineral Resource Estimates” and “Note Regarding Forward-looking Statements” in this prospectus, where we describe additional uncertainties associated with our business and the forward-looking statements included, or to the extent not superseded hereby, incorporated by reference in this prospectus.

Risks Related to our Business

The COVID-19 pandemic has resulted in significant disruption and volatility in financial and commodities markets, restrictions on the conduct of business in many jurisdictions and caused general economic uncertainty, any of which may have a significant adverse effect on our operations, business and financial condition.

In March 2020, the World Health Organization declared a global pandemic related to COVID-19. The current and expected impacts on global commerce are far-reaching. To date there has been significant stock market volatility, volatility in commodity and foreign exchange markets, restrictions on the conduct of business in many jurisdictions and the global movement of people has become restricted. There continues to be significant ongoing uncertainty surrounding COVID-19 and the extent and duration of the impacts that it may have on demand and prices for the commodities we produce, on our suppliers, on our employees and on global financial markets.

We continue to make efforts to safeguard the health of our employees, while continuing to operate safely and responsibly maintain employment and economic activity. These measures combined with commodity market fluctuations resulting from COVID-19 have affected our financial results.

We remain confident in the longer-term outlook for our major commodities, however, global economic uncertainty and COVID-19 had a significant negative effect on the prices for our products in the quarter ended June 30, 2020. The extent and duration of impacts that COVID-19 may have on demand and prices for our commodities, on our suppliers and employees and on global financial markets over the remainder of the year and going forward is not known at this time, but could be material. Due to the ongoing uncertainty surrounding COVID-19 and the extent and duration of the impacts on our business, we suspended our previously issued 2020 annual guidance and on July 22, 2020 issued updated 2020 annual guidance.

We recorded a property, plant and equipment impairment in the first quarter of 2020 of $647 million ($474 million, after-tax) related to our interest in Fort Hills. There is heightened potential for further impairments over the balance of 2020. Write-downs of inventory or reversals of write-downs taken in the first or second quarter may occur as commodity prices and foreign exchange rates fluctuate. At the onset of the pandemic, we slowed or suspended operations at certain of our mines to safeguard the health of our employees. In the current environment, assumptions about future commodity prices, exchange rates, interest rates and customer credit performance are subject to greater variability than normal, which could in future significantly affect the valuation of our assets, both financial and non-financial. Our understanding of the longer-term impacts of COVID-19 on commodity markets continues to develop and there is heightened potential for changes in these estimates over the balance of 2020.

In the quarter ended June 30, 2020, we expensed costs of approximately $260 million relating to COVID-19 as a result of reduced production levels at our operations, including the temporary shut-down of our Antamina operations, the suspension of construction on our QB2 project, increased safety equipment requirements and physical distancing measures. Of the $260 million, $34 million was recorded in cost of sales and $151 million

6

was recorded in other operating income (expense). The remaining $75 million of costs relates to interest that would have been capitalized if QB2 was not suspended.

While the full extent of the impact that the COVID-19 pandemic will have is unknown, continued disruption and volatility in financial and commodities markets, restrictions on the conduct of business and continued general economic uncertainty, and any potential shutdown of our operations or the operations of other businesses, industries or economies upon which we rely, may have a significant adverse effect on our operations, business and financial condition.

To the extent that the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described herein, including, but not limited to, risks relating to fluctuations in the market price of our products, our development projects, our reputation and community relations, volatility in commodity and financial markets, market access restrictions or tariffs, fluctuations in the price and availability of consumed commodities, labor unrest and disturbances, availability of skilled employees, depletion of mineral reserves, disruptions of information technology systems, changes in law or policies in relation to taxes, fees and royalties, and transportation services from third parties.

We face risks in the mining, metals and oil business.

The business of exploring for natural resources and the development and production of mining operations are inherently risky. Many projects are unsuccessful and there are no assurances that current or future exploration or development programs will be successful. During development and after the commencement of mining operations, our projects and operations are subject to significant risks and hazards, some beyond our control, including environmental hazards, industrial accidents, unexpected increases in capital or operating costs, unusual or unexpected geological formations, unanticipated metallurgical difficulties, ground control problems, restrictions on water availability, seismic activity, weather events, security incidents, failure of unproven or evolving technology, labor-force disruptions, supply problems and delays, and natural disasters, such as flooding. Our mining, oil and exploration operations require reliable infrastructure such as roads, rail, ports, pipelines, power sources and transmission facilities, and water supplies. As ore bodies become more remote, and as availability of fresh water becomes more restricted in certain areas, the complexity and cost of infrastructure for mining projects are increasing. Availability and cost of infrastructure affects the production and sales from operations, as well as our capital and operating costs. The Trail metallurgical operations, our concentrate mills, our coal preparation plants, and our oil extraction and processing plants are also subject to risks and hazards, including process upsets and equipment malfunctions. Equipment and supplies may from time to time be unavailable on a timely basis. Our operating mines and certain closed sites have large tailings dams, containing effluent that remains after recoverable metals have been removed from the ore during processing, which could fail as a result of seismic activity or for other reasons. The occurrence of any of the foregoing could result in damage to or destruction of mineral properties or production or logistics facilities, personal injuries or death, environmental damage, delays or interruption of production, failure to achieve production targets, increases in operating costs, monetary losses, legal liability and/or adverse governmental action, any of which may have a significant adverse effect our operations, business and financial condition.

Fluctuations in the market price of steelmaking coal, base metals, blended bitumen and specialty metals may significantly adversely affect the results of our operations.

The results of our operations are significantly affected by the market price of steelmaking coal, base metals, blended bitumen, and specialty metals, which are cyclical and subject to substantial price fluctuations. Our earnings are particularly sensitive to changes in the market price of steelmaking coal, copper, zinc and blended bitumen. Market prices can be affected by numerous factors beyond our control, including new sources of production of our products, levels of supply and demand for our products and for a broad range of other industrial products, substitution of new or different products in critical applications for our existing products,

7

expectations with respect to the rate of inflation, the relative strength of the Canadian dollar and of certain other currencies, interest rates, speculative activities, transportation restrictions and pipeline capacity, global or regional political or economic crises, government policy changes, including taxes and tariffs, trade disputes or the potential for trade disputes and sales of commodities by holders in response to such factors.

Prices for our blended bitumen can be influenced by global and regional factors that are beyond our control and can result in a high degree of volatility, including, among other things, constraints on rail and pipeline capacity, regional supply and demand imbalances, political developments, decisions by the Organization of the Petroleum Exporting Countries (OPEC) or governments to impose or not impose quotas, compliance or non-compliance with agreed quotas by OPEC members, and weather.

The Chinese market is a significant source of global demand for commodities, including steelmaking coal, zinc and copper. A sustained slowdown in China’s growth or demand, or a significant slowdown in other markets, in either case that is not offset by reduced supply or increased demand from other regions, could have an adverse effect on the price and/or demand for our products. COVID-19 and efforts to contain it may have a significant effect on Chinese commodity prices and demand and potentially broader impacts on the global economy

A prolonged period of low and/or volatile commodity prices, particularly of one or more of our principal products, could have a significant adverse effect on our operations, business and financial condition. If prices should decline below our cash costs of production and remain at such levels for any sustained period, we could determine that it is not economically feasible to continue commercial production at any or all of our operations. We may also curtail or suspend some or all of our exploration activities, with the result that our depleted reserves are not replaced.

A substantial reduction or sustained decrease in hard coking coal prices would have a material adverse effect on our business. Our general policy has been not to hedge changes in prices of our mineral or energy products. From time to time, however, we have in the past and may in the future undertake hedging programs in specific circumstances, with an intention to reduce the risk of declines in a commodity’s market price while optimizing upside participation, to maintain adequate cash flows and profitability to contribute to the long-term viability of our business. There are, however, risks associated with hedging programs including, among other things, the risk of opportunity losses in the event of an increase in the world price of the commodity, an increase in interest rates, the possibility that rising operating costs will make delivery into hedged positions uneconomic, counterparty risks and the impact of production interruption events.

We face risks associated with the issuance and renewal of permits.

Numerous governmental permits or approvals are required for mining operations. We have significant permitting activities currently underway for new projects and for the extension or expansion of existing operations. In addition, many existing permits require periodic renewals. Examples of current significant permitting efforts include the Quebrada Blanca Phase 2 project and our steelmaking coal mine operations in the Elk Valley. When we apply for these permits and approvals, we are often required to prepare and present data to various government authorities pertaining to the potential effects or impacts that any proposed project may have on the environment and on communities. The authorization, permitting and implementation requirements imposed by any of these authorities may be costly and time-consuming, and may delay commencement or continuation of mining operations. There can be no certainty that these approvals or permits will be granted in a timely manner, or at all. Regulations also provide that a mining permit or modification can be delayed, refused or revoked. In certain jurisdictions, some parties have extensive rights to appeal the issuance of permits or to otherwise intervene in the regulatory process. Permits may be stayed or withdrawn during the pendency of appeals.

Past or ongoing violations of mining or environmental laws could provide a basis to revoke existing permits

8

or to deny the issuance of additional permits. In addition, evolving reclamation or environmental concerns may threaten our ability to renew existing permits or obtain new permits in connection with future development, expansions and operations.

Delays associated with permitting may cause us to incur material additional costs in connection with the development of new projects or the expansion of existing operations, including penalties or other costs in relation to long-lead equipment orders and other commitments associated with projects or operations. Failure to obtain certain permits may result in damage to our reputation, cessation of development of a project or inability to proceed with the expansion of existing operations, increased costs of development or production and litigation or regulatory action, any of which may have a material adverse effect on our operations, business and financial position.

Ongoing operation of our steelmaking coal mines in the Elk Valley, British Columbia, continually requires new permits or amendments to existing permits from applicable government agencies. We received approval in 2014 of a plan to manage water quality for the Elk Valley watershed as a whole and are subject to permits giving effect to that plan. The Elk Valley Water Quality Plan is intended to provide a regulatory framework for permitting current and future projects and for managing the cumulative effects of new projects. The plan contemplates ongoing monitoring of the receiving environment, and adjustment of water quality targets if unacceptable environmental impacts are identified. There can be no assurance that the water quality targets set out in our valley-wide water quality management plan will prove to be suitably protective of the environment, that our planned mitigation efforts will be sufficient to meet those targets or that ongoing monitoring will not disclose unanticipated environmental effects of our operations that will require additional mitigation. For example, we previously announced that we were working to address an issue regarding selenium compounds in effluent from the West Line Creek active water treatment facility, which was constructed as part of our Elk Valley Water Quality Plan, and we delayed commencement of construction of our next water treatment facility, at our Fording River Operations, to incorporate certain related design changes. We are currently not in compliance with certain of the water quality parameters set out in the Elk Valley Water Quality Plan and related permits.

Fish surveys have revealed unanticipated declines in fish populations in mine-affected waters, the causes of which are not clear. Until the causes of this decline are identified and appropriate mitigation measures are in place, we may face delays in permitting or restrictions on our mining activities in the Elk Valley. See “Individual Operations—Steelmaking Coal—Elk Valley Water Quality Management Plan” in the Teck AIF, incorporated by reference in this prospectus for more details.

Notwithstanding the approval of the plan in 2014, during the third quarter of 2018, we received notice from Canadian federal prosecutors of potential charges under the Fisheries Act in connection with discharges of selenium and calcite from coal mines in the Elk Valley. See “Legal Proceedings and Regulatory Actions—Fisheries Act” in the Teck AIF, incorporated by reference in this prospectus for more details. We cannot operate our Elk Valley coal mines in compliance with the Fisheries Act and its current associated regulations. Federal regulatory issues may create additional difficulties in obtaining permits for our Elk Valley operations, whether or not charges are eventually laid or we are successful in defending any charges.

Any negative developments relating to matters referred to above may result in enforcement action by including potential prosecutions, or consequential delays in permitting new mining areas in the Elk Valley or on restrictions being placed on our mining activities in the Elk Valley, which would limit our ability to maintain or increase steelmaking coal production in accordance with our long-term plans or to realize the projected mine life of our operations. The potential shortfall in production may be material and may have a material adverse effect on our operations, business and financial position.

We face risks associated with our development projects.

We are involved in a number of development projects. Our major projects include our Quebrada Blanca Phase 2 project. We also have a number of other projects in our development portfolio, including, NuevaUnión,

9

Galore Creek, San Nicolás, Mesaba and Zafranal. Development and exploitation of the hypogene resource, a primary sulphide ore body located beneath shallow zones of ore affected by weathering processes, at Quebrada Blanca Phase 2 will require considerable capital expenditures and various environmental and other permits and governmental authorizations. NuevaUnión, San Nicolás and Zafranal are also all in early stages of development. Our ability to maintain or increase our annual production of our principal products is dependent, to a significant extent, on our ability to bring new mines into production and expand existing mines.

Development projects typically require a number of years and significant expenditures before production is possible. Estimates of such expenditures or of future operating costs may differ materially from actual capital or operating costs. Such projects could experience unexpected problems or delays during development, production or mine start-up.

Construction and development of these projects are subject to numerous risks, including, without limitation, risks relating to:

10

The economic feasibility analysis with respect to each project is based upon, among other things, the interpretation of geological data obtained from drill holes and other sampling techniques, feasibility studies, pricing assumptions for inputs and products produced, the configuration of the ore body, expected recovery dates, anticipated climate conditions and estimates of labor, productivity, royalty and tax rates. Actual operating results may differ materially from those anticipated.

Product alternatives may reduce demand for our products.

Most of our products are primarily used in specific applications, such as the use of copper in electrical wiring and electronic applications, the use of refined zinc to galvanize steel, the use of steelmaking coal in steel production and the use of heavy crude oils, such as our blended bitumen, to make refined petroleum products. Alternative technologies are continually being investigated and developed with a view to reducing production costs or for other reasons, such as minimizing environmental or social impact. If competitive technologies emerge that use other materials in place of our products, demand and price for our commodities might fall.

For example, substantially all of our coal production is high-quality hard coking coal, which commands a significant price premium over other forms of coal because of its value in use in blast furnaces for steel production. High-quality hard coking coal is globally scarce, and has specific physical and chemical properties that are necessary for efficient blast furnace operation. Steel producers are continually investigating alternative steel production technologies with a view to reducing production costs. Many of those alternative technologies are designed to use lower quality coals or other sources of carbon instead of higher cost high-quality hard coking coal. While conventional blast furnace technology has been the most economic large-scale steel production technology for decades, and while emergent technologies typically take many years to commercialize, there can be no assurance that over the longer term competitive technologies not reliant on hard coking coal could emerge, which could reduce demand and price premiums for hard coking coal.

Climate change may have an adverse effect on demand for our products or on our operations.

As the world transitions to a lower-carbon economy, there is increasing focus on low-carbon technologies to replace carbon-intensive ones. This is increasing the pressure on steel producers to develop less carbon-intensive production processes that do not rely on high quality hard coking coal. Government action to address climate change and societal pressures towards a lower-carbon economy may reduce the demand for our products. Concerns regarding climate change may lead to technological development of alternatives to certain of our products, such as steelmaking coal and oil. Climate change and policy responses to climate change may have similar impacts on our customers, reducing demand for our products.

A decrease in demand for our products, particularly of one or more of our principal products, could have a significant adverse effect on our operations, business and financial condition. Climate change may, among other things, cause or result in sea level increases, changes in precipitation, changes in fresh water levels, increases in extreme weather events, melting permafrost in the Arctic and resource shortages. While our mining and refining operations are located well above sea level, an increase in sea level could affect our ocean transportation and shipping facilities. Extreme weather events have the potential to disrupt operations at our mines and to impact our transportation infrastructure, including by affecting the length of our shipping season at our Red Dog mine.

Climate change may also result in shortages in certain consumables and other products required to sustain our operations, and any such shortage could impact our production capacity. Our Red Dog mine is located in the Arctic and could be materially impacted by melting permafrost.

11

Although we make efforts to anticipate potential costs associated with climate change to mitigate the physical risks of climate change, and work with governments to influence regulatory requirements regarding climate change, there can be no assurances that these efforts will be effective or that climate change or associated governmental action will not have an adverse impact on our operations and therefore our profitability.

Regulatory efforts to control or reduce greenhouse gas emissions or societal pressures in relation to climate change could materially negatively affect our business.

Our businesses include several operations that emit large quantities of carbon dioxide, or that produce or may produce products that emit large quantities of carbon dioxide when consumed by end users. This is particularly the case with our steelmaking coal operations and our oil sands operation and projects. Carbon dioxide and other greenhouse gases are the subject of increasing public concern and regulatory scrutiny. See “Health and Safety and Environmental Protection—Climate Change and Carbon Pricing” in the Teck AIF, incorporated by reference in this prospectus.

Climate change may result in increased regulations for our operations or those of our customers and/or restrict the development of our projects, which may increase costs and/or limit production. Changes in carbon regulation or taxation may decrease demand for our products, particularly steelmaking coal and blended bitumen.

The primary source of greenhouse gas emissions in Canada is the use of hydrocarbon energy. Our operations depend significantly on hydrocarbon energy sources to conduct daily operations, and there are typically no economic substitutes for these forms of energy. While carbon tax legislation has been adopted in several jurisdictions where we operate, it is not yet possible to reasonably estimate the nature, extent, timing and cost of any future taxes or other programs that may be enacted.

Most of our steelmaking coal products are sold outside of Canada, and sales are not expected to be significantly affected by the greenhouse gas emissions targets that Canada committed to under the Paris Agreement or the resulting provincial and federal carbon tax legislation. All of our blended bitumen is sold in North America and such sales are not currently subject to any significant carbon tax or similar requirements. However, the broad adoption of emission limitations or other regulatory efforts to control or reduce greenhouse gas emissions by other countries could materially negatively affect the demand for steelmaking coal and oil, as well as restrict development of new steelmaking coal or oil sands projects and increase production and transportation costs.

As a result of public concern regarding climate change, natural resource companies, like Teck, face increasing public scrutiny of our activities and our impacts. Societal pressures in relation to climate change may adversely affect our social license to operate and may impair our ability to obtain required permits, increase regulatory action or result in litigation against us, and negatively affect our reputation and our relationships with stakeholders. Concerns around climate change may also affect the market price of our securities as institutional investors and others may divest interests in carbon intensive industries due to societal pressures. See “—Damage to our reputation may result in decreased investor confidence, challenges in maintaining positive community relations and increased risks in obtaining permits or financing for our development properties and expansions to our existing operations.”

Failure to comply with environmental, health and safety laws may have a material adverse effect on our operations and projects.

Environmental, health and safety legislation affects nearly all aspects of our operations, including mine development, worker health and safety, waste disposal, emissions controls, and protection of endangered and protected species. Compliance with environmental, health and safety legislation can require significant expenditures and can restrict the manner in which mining and other operations can be conducted.

12

In addition, failure to comply with environmental, health or safety legislation may result in the imposition of significant fines and/or penalties, the temporary or permanent suspension of operations or other regulatory sanctions including cleanup costs arising out of contaminated properties, damages, damage to reputation, the loss of existing, or inability to obtain future, permits and civil suits or criminal charges. Exposure to these liabilities arises not only from our existing operations, but also from operations that have been closed or sold to third parties. Some of our historical operations have generated significant environmental contamination and other issues in the context of current regulation. We could also be held liable for worker exposure to hazardous substances. There can be no assurance that we will at all times be in compliance with all environmental, health and safety regulations or that steps to achieve compliance would not materially adversely affect our operations, business and financial condition.

Changes in environmental, health and safety laws may have a material adverse effect on our operations and projects.

In February 2018, the Government of Canada proposed new regulations under the Fisheries Act relating to coal mining effluent. While these regulations are still in development, they could impose significant costs and operating limitations on our steelmaking coal operations. In the absence of these new regulations, our coal mining activities cannot be conducted in compliance with the Fisheries Act and we may face significant liability as a result. There can be no assurance that the new regulations will completely remedy this situation.

In 2019, the Canadian Impact Assessment Act came into force with significant changes to the federal government’s current environmental assessment and regulatory processes for resource development projects. While the new legislation does not affect Teck’s projects that are already in regulatory approval processes it will apply to new projects which meet certain criteria. Similarly in 2019, the British Columbia government reformed the province’s environmental assessment process for resource projects, introducing significant new changes into the environmental assessment process for industrial and resource projects in British Columbia including new rules surrounding project notifications, early engagement and increased public participation, along with new timelines dictating when certain steps must be taken throughout the environmental assessment process. These changes and any other new legislation may affect our ability to obtain or renew permits for our operations and projects in an efficient and cost-effective manner or at all.

In addition, the Government of British Columbia has recently introduced legislation to implement the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) in British Columbia. The legislation commits to a systematic review of the province’s laws with respect to UNDRIP, while also encouraging new agreements with Indigenous nations that are intended to address outstanding governance questions around the nature of Indigenous rights and title interests in B.C. While the potential risks of this legislation remain to be determined they could be significant, particularly with respect to our permitting efforts.

Environmental, health and safety laws and regulations are evolving in all jurisdictions where we have activities. We are not able to determine the specific impact that future changes in environmental laws and regulations may have on our operations and activities, and our resulting financial position; however, we anticipate that capital expenditures and operating expenses will increase in the future as a result of the implementation of new and increasingly stringent environmental, health and safety regulations. For example, emissions standards for carbon dioxide and sulphur dioxide are becoming increasingly stringent, as are laws relating to the use and production of regulated chemical substances and the consumption of water by industrial activities. Further changes in environmental, health and safety laws, new information on existing environmental, health and safety conditions or other events, including legal proceedings based upon such conditions, or an inability to obtain necessary permits, could require increased financial reserves or compliance expenditures, or otherwise have a material adverse effect on us. Changes in environmental, health and safety legislation could also have a material adverse effect on product demand, product quality and methods of production and distribution. In the event that any of our products were demonstrated to have negative health effects, we could be exposed to workers’ compensation and product liability claims, which could have a material adverse effect on our business.

13

Damage to our reputation may result in decreased investor confidence, challenges in maintaining positive community relations and increased risks in obtaining permits or financing for our development properties and expansions of our existing operations.

Damage to our reputation can occur from our actual or perceived actions or inactions and a variety of events and circumstances, many of which are out of our control. The growing use of social media to generate, publish and discuss community news and issues and to connect with others has made it significantly easier for individuals and groups to share their opinions of us and our activities, whether true or not. We do not directly control how we are perceived by others and loss of reputation could result in, among other things, a decrease to the price of our securities, decreased investor confidence, challenges in maintaining positive relationships with the communities in which we operate and other important stakeholders and increased risks in obtaining permits or financing for our development properties or expansions to our existing operations, any of which could have a material adverse effect on our operations, development projects, business and financial position.

We face risks associated with our reclamation obligations.

We are required to reclaim properties as mining progresses and after mining is completed and specific requirements vary among jurisdictions. We are required by various governments in the jurisdictions in which we operate to provide financial assurances to cover any reclamation obligations we may have at our mine sites. The amount of these financial assurances is significant and is subject to change from time to time by the governments in the jurisdictions in which we operate, and may exceed our estimates for such costs. The amount and nature of our financial assurance obligations depend on a number of factors, including our financial condition and reclamation cost estimates.

Reclamation cost estimates can escalate because of new regulatory requirements, changes in site conditions or conditions in the receiving environment, or changes in analytical methods or scientific understanding of the impacts of various constituents in the environment. Since 2016, the B.C. government has been carrying out a review of its financial assurance requirements for reclamation obligations. While it is not clear what the new requirements will be or when they will be implemented, we expect they will result in an increase to our financial assurance requirements, for both our ongoing operations and our projects in B.C.

Changes to the form or amount of our financial assurance obligations in respect of reclamation obligations could significantly increase our costs, making the maintenance and development of existing or new mines less economically feasible. Increases in financial assurance requirements could severely impact our credit capacity and our ability to raise capital for other projects or acquisitions. We may be unable to obtain letters of credit or surety bonds to satisfy these requirements, in which case we may be required to deposit cash as financial assurance. If we are unable to satisfy these requirements, we may face loss of permits, fines and other material and negative consequences.

Although we currently make provisions for our reclamation obligations, there can be no assurance that these provisions will be accurate in the future. Any underestimated or unanticipated reclamation costs could materially affect our business, operations and financial condition. Failure to provide regulatory authorities with the required financial assurances could potentially result in the closure of one or more of our operations, which could result in a material adverse effect on our operations and therefore our profitability.

Failure to secure water rights could have negative effects on our operations and financial condition.

Water rights are an area of significant and increasing focus for our foreign operations and community relations are significantly impacted by access and sourcing of water. Our mining operations require significant quantities of water for mining, ore processing and related support facilities. Certain of our operations and projects are located in areas where water is scarce and competition among users for access to water is significant. If water

14

supplies become scarce or are negatively affected by environmental events or factors such as drought, water supplies to our operations might be reduced in order to maintain supply to the local communities in which we operate or for ecological purposes, whether or not we have legal rights to draw water. Laws and regulations may be introduced in certain jurisdictions which could limit our access to water resources.

Any reduction in the availability of water may preclude development of otherwise potentially economic mineral deposits or may negatively affect costs, production and/or sales from our affected operations.

We are subject to legal proceedings, the outcome of which may affect our business.

The nature of our business subjects us to numerous regulatory investigations, claims, lawsuits and other proceedings in the ordinary course of our business. The results of these legal proceedings cannot be predicted with certainty and the costs of these legal proceedings can be significant. Additionally, although largely unsuccessful to date, natural resource issuers are facing a significant increase in climate change related litigation. There can be no assurances that these matters will not have a material adverse effect on our reputation, our support by various stakeholders, our ability to secure permits, the market price of our securities or on our operations, business or financial condition generally. See “Legal Proceedings and Regulatory Actions” in the Teck AIF, incorporated by reference in this prospectus.

We face risks associated with our joint venture operations and projects.

A number of our projects and operations are developed and operated through joint venture or shared ownership arrangements with third parties. These joint arrangements include, among others, Quebrada Blanca Phase 2, Fort Hills, Antamina, NuevaUnión, Zafranal, Galore Creek, Elkview and Greenhills. We face risks from the fact that at certain of our operations, like Fort Hills and Antamina, we are a minority partner and certain major decisions may be made without our consent, meaning we may not have control over a number of factors including, timing and amount of capital and operating expenditures, operation and production decisions, risk management and other operational practices.

We also face risks from the fact that at certain other projects, like NuevaUnión and Galore Creek, in which we hold a 50% interest, many decisions require the consent of our partner, and, even at projects or operations where we hold a majority interest, such as Quebrada Blanca, Zafranal, Elkview and Greenhills, major decisions affecting the project or operation may require agreement with our partners. Dispute resolution provisions with respect to major decisions in the relevant agreements may result in major decisions being made without our consent or may trigger other remedies.

The success and timing of these operations and projects depend on a number of factors that may be outside our control including, the financial resources of our partners and the objectives and interests of our partners. While joint venture partners may generally reach consensus regarding the direction and operation of the operation or project, there are no assurances that this will always be the case or that future demands and expectations will continue to align. Failure of joint venture partners to agree on matters requiring consensus may lead to development or operational delays, failure to obtain necessary permits or approvals in an efficient manner or at all, remedies under dispute resolution mechanisms, or the inability to progress with production at the relevant operation or development of the relevant project in accordance with expectations or at all, which could materially affect the operation or development of such projects or operations and our business and financial condition.

Volatility in commodity markets and financial markets may adversely affect our ability to operate and our financial condition and may cause the market price of our securities to fluctuate significantly.

Recent global financial conditions and commodity markets have been volatile. From time to time, access to financing has been negatively affected by many factors, including the financial distress of banks and other credit

15

market participants and global market uncertainty. This volatility has from time to time affected and may in the future affect our ability to obtain equity or debt financing on acceptable terms, and may make it more difficult to plan our operations and to operate effectively. If volatility or market disruption affects our access to financing on reasonable terms, our operations and financial condition could be adversely affected.

Furthermore, the market price of our securities may fluctuate significantly in response to a number of factors, many of which are beyond our control, including, without limitation, variations in our operating results, changes in market conditions, announcements by us of strategic developments, acquisitions and other material events, speculation about us in the press or investment community, changes in market valuation of similar companies, developments in the mining business generally, activism, regulatory changes and changes in political environments and changes in global financial markets generally. Any of these events could result in a material decline in the price of our securities.

Future funding requirements may affect our business and we may not have access to credit in the future.

Future investments, including development projects, acquisitions and other investments, may require significant capital expenditures. Our operating cash flow may not be sufficient to meet all of these expenditures depending on the timing and costs of development. As a result, new sources of capital may be needed to fund acquisitions or these investments. Additional sources of capital may not be available when required or on acceptable terms and as a result we may be unable to grow our business, finance our projects, take advantage of business opportunities, fund our ongoing business activities, respond to competitive pressure, retire or service outstanding debt or refinance maturing debt.

We have significant financial support in the form of outstanding letters of credit issued by banks, which reduces the amount of other credit, including loans, that issuing banks may be willing to extend to us by way of debt financing. We also have a significant amount of surety bonds issued by insurance companies. These letters of credit and surety bonds are required for a number of purposes, mainly as security for reclamation obligations. If we are no longer rated investment grade, we may be required to deliver a significant amount of letters of credit to support our parent guarantees of the take-or-pay commitments in respect of our Fort Hills downstream arrangements and Quebrada Blanca Phase 2 power arrangements.

The surety bonds and the credit facilities that support our letters of credit do not currently require us to deliver cash collateral or other security, although we may elect to do so from time to time to reduce borrowing costs. If letters of credit, surety bonds or other acceptable financial assurance are not available to us on an unsecured basis, we may be required to deliver cash collateral to a financial institution that will issue the financial assurance, which would reduce our cash available for use in our business.

In addition, certain of our letters of credit are issued under uncommitted standby facilities. Our standby letter of credit facilities may be terminated at the election of the bank counterparty upon at least 90 days’ notice. In the event that a standby letter of credit facility is terminated, we would be required to deliver cash collateral to the bank counterparty if we were unable to terminate the letter of credit issued by the bank. Providers of our surety bonds also have the right to require the delivery of cash collateral upon 60 days’ notice.

Investor or general societal pressures may limit the appetite of certain institutions to lend to, or hold debt or equity securities of, issuers, such as Teck, in carbon-intensive industries or industries with a track record of social and environmental controversy, despite our efforts to adhere to leading industry practices regarding social and environmental matters.

Our credit ratings have been subject to change over the years. There can be no assurance that the credit ratings currently assigned to Teck’s debt securities will not be lowered. A downgrade by any rating agency could adversely affect the value of our outstanding debt securities, the value of our existing debt and our ability to

16

obtain new financing on favorable terms, if at all, and may increase our borrowing costs and require us to provide additional financial support in respect of certain obligations relating to our operations, which in turn could have a material adverse effect on our operations, business and financial position.

We may be adversely affected by interest rate changes.

Our exposure to changes in interest rates results from investing and borrowing activities undertaken to manage our liquidity and capital requirements. We have incurred indebtedness that bears interest at fixed and floating rates, and we may from time to time enter into interest rate swap agreements to effectively convert some fixed rate exposure to floating rate exposure. There can be no assurance that we will not be materially adversely affected by interest rate changes in the future. In addition, our use of interest rate swaps exposes us to the risk of default by the counterparties to those arrangements. Any default by a counterparty could have a material adverse effect on our business.

We may be adversely affected by currency fluctuations.

Our operating results and cash flow are affected by changes in currency exchange rates relative to the currencies of other countries. Exchange rate movements can have a significant impact on results, as a significant portion of our operating costs are incurred in Canadian and other currencies, most revenues are earned in U.S. dollars, and a significant portion of the capital costs for QB2 will be incurred in Chilean pesos. To reduce the exposure to currency fluctuations, we enter into foreign exchange contracts from time to time, but these hedges do not eliminate the potential that those fluctuations may have an adverse effect on us. In addition, foreign exchange contracts expose us to the risk of default by the counterparties to those contracts, which could have a material adverse effect on our business. In addition, our operating costs are influenced by the strength of the currencies of those countries where our operations are located, such as Chile, Peru and the United States.

Our general policy has been not to hedge currency exchange rates. From time to time, however, we have in the past and may in the future undertake currency hedging activities in specific circumstances. There can be no assurance that we will enter into these currency hedging activities or that these currency hedging activities will not cause us to experience less favorable economic outcomes that we would have experienced if we did not engage in such activities.

We face competition in product markets and from other natural resource companies.

The mining industry in general is intensely competitive and even if commercial quantities of mineral resources are developed, a profitable market may not exist for the sale of the minerals. We must sell base metals, metal concentrates, by-product metals and concentrate, blended bitumen and steelmaking coal at prices determined by world markets over which we have no influence or control. Our competitive position is determined by our costs in comparison to those of other producers in the world. If our costs increase due to our locations, grade and nature of orebodies, foreign exchange rates, government policy changes, permitting costs or our operating and management skills, our profitability may be affected. We have to compete with larger companies that have greater assets and financial and human resources than us and which may be able to sustain larger losses than us.

We also compete with other natural resource companies to obtain specialized equipment, components and supplies to develop our projects or operate our mines. Competition in these areas could result in significant delays or increased costs to us in the development of our projects or the operation of our mines.

In addition, we face strong competition for exploration properties. Competition in this area could impede our ability to acquire suitable exploration properties on reasonable terms or at all in order to offset the depletion of our current reserves.

17

We may face market access restrictions or tariffs.

Access to our markets may be subject to ongoing interruptions or trade barriers due to policies and tariffs of individual countries, and the actions of certain interest groups to restrict the import of certain commodities. Our products may also be subject to tariffs that do not apply to producers based in other countries. In 2018, the Chinese government imposed tariffs on our zinc and lead concentrates produced in the U.S. While these tariffs did not materially affect our business or our access to Chinese markets, there is no assurance that they will not do so in the future or that those tariffs will not increase in the future. The Chinese government has also from time to time placed restrictions on imports of steelmaking coal. Other than the foregoing, there are currently no significant trade barriers existing or impending of which we are aware that do, or could, materially affect our access to certain markets; however, there can be no assurance that our access to these markets will not be restricted in the future, or that tariffs or similar measures will not impair the competitiveness of our products.

Fluctuations in the price and availability of consumed commodities affect our costs of production.

Prices and availability of commodities consumed or used in connection with exploration, development, mining, smelting, refining and blending, such as natural gas, diesel, oil, diluent and electricity, as well as reagents such as copper sulphate, fluctuate and these fluctuations affect the costs of production at our various operations. Our smelting and refining operations at Trail require concentrates, some of which are produced at our Red Dog mine and some of which we purchase from third parties. The availability of those concentrates and the treatment charges we can negotiate fluctuate depending on market conditions. These fluctuations can be unpredictable, can occur over short periods, and may have a material adverse impact on our operating costs or on the timing and costs of various projects. Our general policy is not to hedge our exposure to changes in prices of the commodities we use in our business.

We could be subject to potential labor unrest or other labor disturbances as a result of the failure of negotiations in respect of our collective agreements.

Approximately 5,900 of our approximately 10,100 regular employees (as of December 31, 2019) are employed under collective bargaining agreements. We could be subject to labor unrest or other labor disturbances as a result of delays in or the failure of negotiations in respect of our collective agreements, which could, while ongoing, have a material adverse effect on our business. See “Description of the Business—Human Resources” in the Teck AIF, incorporated by reference in this prospectus for a description of our regular employee category and the expiry dates of the collective bargaining agreements covering unionized employees at our material projects.

We may not be able to hire enough skilled employees to support our operations.

We compete with other mining companies to attract and retain key executives and skilled and experienced employees. The mining industry is labor intensive and our success depends to a significant extent on our ability to attract, hire, train and retain qualified employees, including our ability to attract employees with needed skills in the geographic areas in which we operate. We face competition for limited candidates in many trades and professions, and may see current employees leave to pursue other opportunities. We could experience increases in our recruiting and training costs, and decreases in our operating efficiency, productivity and profit margins if we are not able to attract, hire and retain a sufficient number of skilled employees to support our operations.

Our reserve and resource estimates may prove to be incorrect.

Disclosed reserve and mine life estimates should not be interpreted as assurances of mine life or of the profitability of current or future operations. We estimate and report our mineral and oil and gas reserves and resources in accordance with the requirements of the applicable Canadian securities regulatory authorities and industry practice.

18

We disclose both mineral reserves and mineral resources. Mineral resources are concentrations or occurrences of minerals that are judged to have reasonable prospects for economic extraction, but for which the economics of extraction cannot be assessed, whether because of insufficiency of geological information or lack of feasibility analysis, or for which economic extraction cannot be justified at the time of reporting. Consequently, mineral resources are of a higher risk and are less likely to be accurately estimated or recovered than mineral reserves.

In general, our mineral reserves and resources are estimated by persons who are, or were at the time of their report, employees of the respective operating company for each of our operations under the supervision of our employees. These individuals are not “independent” for purposes of applicable securities legislation. Generally, we do not use outside sources to verify mineral reserves or resources, except at the initial feasibility stage and through periodic external audits.

We disclose both oil and gas reserves and resources other than reserves in accordance with applicable Canadian securities requirements. Resources other than reserves (further defined as contingent or prospective) are less certain due to geologic, economic, legal, market, political, social, or regulatory conditions, as well as level of corporate commitment. These resources may not be developed, and are less likely to be accurately estimated or recovered than reserves.

The reserve and resource figures included or incorporated in this prospectus by reference are estimates based on the interpretation of limited sampling and subjective judgments regarding the grade, continuity and existence of mineralization, as well as the application of economic assumptions, including assumptions as to operating costs, production costs, mining and processing recoveries, cut-off grades, long-term commodity prices and, in some cases, exchange rates, inflation rates, capital costs and applicable taxes and royalties. As a result, changes in estimates or inaccuracy of estimates may affect our reserves and resources. The sampling, interpretations or assumptions underlying any reserve or resource estimate may be incorrect, and the impact on reserves or resources may be material.

Should the mineralization and/or configuration of a deposit ultimately turn out to be significantly different from that currently envisaged, or should regulatory standards or enforcement change, then the proposed mining plan may have to be altered in a way that could affect the tonnage and grade of the reserves mined and rates of production and, consequently, could adversely affect the profitability of the mining operations. In addition, short-term operating factors relating to the reserves, such as the need for orderly development of orebodies or the processing of new or different ores, may cause reserve and resource estimates to be modified or operations to be unprofitable in any particular fiscal period.

There can be no assurance that our projects or operations will be, or will continue to be, economically viable, that the indicated amount of minerals or hydrocarbons will be recovered, or that they will be recovered at the prices assumed for purposes of estimating reserves.

The depletion of our mineral reserves may not be offset by future discoveries or acquisitions of mineral reserves.

We must continually replace mineral reserves depleted by production to maintain production levels over the long term. This is done by expanding known mineral reserves or by locating or acquiring new mineral deposits.

There is, however, a risk that depletion of reserves will not be offset by future discoveries of mineral reserves. Exploration for minerals and oil and gas is highly speculative and involves many risks. Few properties that are explored are ultimately developed into producing mines. The reasons why a mineral property may be non-productive often cannot be anticipated in advance. Further, significant costs are incurred to establish mineral or oil and gas reserves and to construct mining and processing facilities. Development projects have no operating

19

history upon which to base estimates of future cash flow and are subject to the successful completion of feasibility studies, obtaining necessary government permits, obtaining title or other land rights, and availability of financing, among other things. In addition, assuming discovery of an economic orebody, a contiguous, well defined mass of material of sufficient ore content to make extraction economically feasible, depending on the type of mining operation involved many years may elapse from the initial phases of drilling until commercial operations are commenced. Accordingly, there can be no assurances that our current work programs will result in any new commercial mining operations or yield new reserves to replace and/or expand current reserves in a timely manner.

Our operations depend on information technology systems, which may be disrupted or may not operate as desired.

We rely on information technology systems and networks in our operations. Our information technology systems are subject to disruption, damage or failure from a variety of sources, including, without limitation, security breaches, cybersecurity attacks, computer viruses, malicious software, natural disasters or defects in software or hardware systems. Our systems and procedures for protecting against such attacks and mitigating such risks may prove to be insufficient in the future and such disruption, damage or failure could result in, among other things, production downtime, operational delays, destruction or corruption of data, damage to reputation, environmental or physical damage to our operations or surrounding areas or legal or regulatory consequences, any of which could have a material adverse effect on our financial condition, operations, production, sales, and business. We could also be adversely affected in a similar manner by system or network disruptions if new or upgraded information technology systems are defective, not installed properly or not properly integrated into our operations.

In addition, as technologies evolve and cybersecurity attacks become more sophisticated, we may incur significant costs to upgrade or enhance our security measures or mitigate potential harm. Our exposure to these risks is expected to increase as we take steps to further integrate information technology in our operations through the adoption of technologies such as autonomous haulage and process control automation.

Title defects or claims may affect our existing operations as well as our development projects and future acquisitions.

Title to our properties may be challenged or impugned. Our mining properties may be subject to prior unregistered agreements, transfers or subject to challenge by governments or private parties. Claims and title may be affected by, among other things, undetected defects. A determination of defective title or a challenge to title rights could impact our existing operations as well as exploration and development projects and future acquisitions, which may have a material adverse effect on our operations, business and cash flow.

Indigenous Peoples’ claims and rights to consultation and accommodation may affect our existing operations worldwide as well as development projects and future acquisitions.

Governments in many jurisdictions must consult with Indigenous Peoples with respect to grants of mineral rights and the issuance or amendment of project authorizations. These requirements are subject to change from time to time. As an example, the Government of British Columbia has recently introduced legislation to implement the United Nations Declaration on the Rights of Indigenous Peoples in British Columbia. See “-Changes in environmental, health and safety laws may have a material adverse effect on our operations and projects.” Consultation and other rights of Indigenous Peoples may require accommodations, including undertakings regarding financial compensation, employment, and other matters in impact and benefit agreements. This may affect our ability to acquire within a reasonable time frame effective mineral titles or environmental permits in these jurisdictions, including in some parts of Canada in which Aboriginal title is claimed, and may affect the timetable and costs of development of mineral properties in these jurisdictions. The

20

risk of unforeseen Indigenous Peoples’ claims or grievances also could affect existing operations as well as development projects and future acquisitions. These legal requirements and the risk of Indigenous Peoples’ opposition may increase our operating costs and affect our ability to expand or transfer existing operations or to develop new projects.

We are subject to changes in law or policy in relation to taxes, fees and royalties.

We are subject to taxes (including income taxes, mineral taxes and carbon taxes), various fees and royalties imposed by various levels of government across the jurisdictions in which we operate. The laws imposing these taxes, fees and royalties and the manner in which they are administered may in the future be changed or interpreted in a manner that materially and adversely affects our business, financial position and results of operations.

We operate in foreign jurisdictions and face added risks and uncertainties due to different economic, cultural and political environments.

Our business operates in a number of foreign countries where there are added risks and uncertainties due to the different economic, cultural and political environments. Some of these risks include nationalization and expropriation, social unrest and political instability, uncertainties in perfecting mineral titles, delays or inability to obtain permits, trade barriers and exchange controls, limitations on repatriation of funds, and material changes in taxation. Further, developing country status or an unfavorable political climate may make it difficult for us to obtain financing for projects in some countries.

A substantial portion of our base metals business is in Chile, which has recently been subject to significant social unrest. While QB2 has the benefit of a tax stability agreement, social conditions in Chile may result in tax increases or may disrupt our business and the impact may be material.

Our business is subject to the Canadian Corruption of Foreign Public Officials Act, the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws, a breach or violation of which could lead to civil and criminal fines and penalties, loss of licences or permits and reputational harm.

We operate in certain jurisdictions that have experienced governmental and private sector corruption to some degree, and, in certain circumstances, strict compliance with anti-bribery laws may conflict with certain local customs and practices. For example, the Canadian Corruption of Foreign Public Officials Act, the U.S. Foreign Corrupt Practices Act, and anti-corruption and anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business or other commercial advantage. In recent years, there has been a general increase in both the frequency of enforcement and the severity of penalties under such laws, resulting in greater scrutiny of and punishment to companies convicted of violating anti-corruption and anti-bribery laws. Furthermore, a company may be found liable for violations by not only its employees, but also by its contractors and third-party agents.

Our Code of Ethics, our Anti-Corruption Policy and other corporate policies mandate compliance with these anti-corruption and anti-bribery laws, and we have implemented training programs, internal monitoring and controls, and reviews and audits to ensure compliance with such laws. However, there can be no assurance that our internal control policies and procedures will always protect us from recklessness, fraudulent behavior, dishonesty or other inappropriate acts committed by our affiliates, employees, contractors or agents. Violations of these laws, or allegations of such violations, could lead to civil and criminal fines and penalties, litigation, loss of operating licences or permits, or withdrawal of mining tenements, and may damage our reputation, which could have a material adverse effect on our business, financial position and results of operations, or cause the market value of our securities to decline. We may face disruption in our permitting, exploration or other activities resulting from our refusal to make “facilitation payments” in certain jurisdictions where such payments are otherwise prevalent.

21

We are highly dependent on third parties for the provision of transportation services and are subject to government action regarding production.

Due to the geographical location of many of our mining properties and operations, we are highly dependent on third parties for the provision of transportation services, including rail, pipeline and port services. We negotiate prices for the provision of these services in circumstances where we may not have viable alternatives to using specific providers, or have access to regulated rate setting mechanisms. Contractual disputes, demurrage charges, rail, pipeline and port capacity issues, availability of vessels and railcars, weather problems or other factors can have a material adverse effect on our ability to transport materials according to schedules and contractual commitments, and result in lower than anticipated sales volumes and revenue. In recent years we have experienced a loss of revenue and an increase in the cost of coal product due, in part, to logistics issues with our transportation service providers.

In 2019, we experienced significant challenges with pipeline capacity for our energy products resulting in low realized prices for our blended bitumen. In December 2018, the Government of Alberta announced temporary curtailment measures that continue to affect our production at Fort Hills and are expected to be in place throughout 2020. There can be no assurances that pipeline capacity challenges or production curtailment will not continue or increase in the future, each of which may materially affect our energy operations and revenue.

A number of our concentrate products include varying amounts of minor elements that are subject to increasing environment regulation, which may expose us to higher smelter treatment charges, penalties or limit our ability to sell certain products.

Our customer smelters are subject to increasingly stringent environmental regulation, in particular with respect to minor elements such as mercury, cadmium and thallium, which could adversely affect their ability to treat copper, zinc and lead concentrates from certain of our operations. We rely on customer smelters to process our concentrates into metals for sale. We are already restricted in our ability to sell certain products in certain jurisdictions for regulatory reasons. We may be required to pay higher smelter treatment charges or specific penalties relating to minor elements present in our concentrates, we may incur additional costs to blend certain products, or we may not be able to sell certain products at all in certain jurisdictions, depending on the regulatory environment.

The profitability of our Trail Operations depends in part on our ability to sell various products that may face more stringent environmental regulation.

In addition to zinc and lead, Trail Operations produces various minor metals and other compounds, which are sold into specialized markets. Changes in market demand for these products, or changes in export regulations or other regulatory restrictions, may limit our ability to sell these products. If we are unable to sell certain products at a profit, we may incur significant storage and disposal costs, or costs to change our production facilities or processes.

Our arrangements relating to our relationship with BC Hydro regarding the Waneta hydroelectric plant may require us to incur substantial costs.

In connection with the sale of our interest in the Waneta hydroelectric plant in 2018, we entered into a 20-year arrangement with BC Hydro, with the ability to renew for an additional 10 years, to use a portion of the energy derived from the Waneta hydroelectric plant for our Trail Operations. Under our arrangement with BC Hydro, Teck Metals is required to provide firm delivery of a portion of the energy from the Waneta hydroelectric plant to BC Hydro until 2036. If Teck Metals does not deliver power as required, it could be required to purchase replacement power in the open market or to pay liquidated damages to BC Hydro based on the market rate for power at the time of the shortfall. These costs are generally not covered by our insurance policies and we could incur substantial costs, especially if the shortfall is protracted.

22

In addition, BC Hydro has contracted to make power available to Teck Metals at favorable rates in amounts sufficient to meet the current and anticipated future requirements of our Trail Operations. If our entitlement to power from the Waneta hydroelectric plant (taking into account our arrangements with BC Hydro) is not sufficient to supply the requirements of our Trail Operations, we may be required to reduce production at our Trail Operations, or purchase power in the open market, in order to address any shortfall. Following expiry of this arrangement we may be required to purchase power in the open market to power our Trail Operations, which may require us to incur substantial additional costs to operate our Trail Operations.

We face risks in connection with our committed downstream arrangements in connection with Fort Hills.

Under the arrangements governing Fort Hills, we are obliged to lift our pro rata share of project production, and to supply the diluent required in order to create a bitumen blend that meets pipeline specifications. In order to meet our lifting obligations and to ensure that our share of project production reaches a market, we are required to enter into commitments to secure tankage and transportation (pipeline, rail) capacity. These commitments involve long-term take-or-pay obligations. There is a risk that there may be delays or interruptions in the availability of appropriate pipeline or rail capacity, that we may be unable to provide the required diluent despite our efforts to secure diluent supply, or that unanticipated events may otherwise interfere with our ability to lift and dispose of our share of Fort Hills production. In any of these events, we may face additional costs or penalties under the Fort Hills arrangements. In addition, interruptions in production at Fort Hills may not relieve us of take-or-pay obligations incurred in connection with our downstream arrangements, causing us to incur significant costs. We may face material losses in any of these situations, which may not be covered by insurance.

Our Red Dog Operations are subject to a limited annual shipping window, which increases the consequences of restrictions on our ability to ship concentrate from the operation.

Like our other mines, our Red Dog mine operates year-round on a 24-hour-per-day basis. Due to sea ice and weather conditions, the annual production of the mine must be stored at the port site and shipped within an approximate 100-day window when sea ice and weather conditions permit. Two purpose-designed shallow draft barges transport the concentrates to deep-water moorings. The barges cannot operate in severe swell conditions.

Unusual ice or weather conditions, or damage to the barges or ship loading equipment could restrict our ability to ship all of the stored concentrate. Failure to ship the concentrate during the shipping season could have a material adverse effect on our sales, as well as on our Trail Operations, and could materially restrict mine production subsequent to the shipping season.

Although we believe our financial statements are prepared with reasonable safeguards to ensure reliability, we cannot provide absolute assurance.

We prepare our financial reports in accordance with accounting policies and methods prescribed by International Financial Reporting Standards as issued by the International Accounting Standards Board. In the preparation of financial reports, management may need to rely upon assumptions, make estimates or use their best judgment in determining the financial condition of the Company. Significant accounting policies are described in more detail in the notes to our annual consolidated financial statements for the year ended December 31, 2019. In order to have a reasonable level of assurance that financial transactions are properly authorized, assets are safeguarded against unauthorized or improper use, and transactions are properly recorded and reported, we have implemented and continue to analyze our internal control systems for financial reporting. Although we believe our financial reporting and financial statements are prepared with reasonable safeguards to ensure reliability, we cannot provide absolute assurance in that regard.

Our insurance may not provide adequate coverage.

We maintain large self-insured retentions and insure against most risks up to reasonably high limits through captive insurance companies. Availability of insurance for mining operations has decreased, and premiums have

23

increased, as a result of recent catastrophic events affecting other mining issuers and a general hardening of insurance markets. Our property, business interruption and liability insurance may not provide sufficient coverage for losses related to certain hazards, and large losses within our captive insurers could have an effect on our consolidated financial position. We may elect not to maintain insurance for certain risks due to the high premiums associated with insuring those risks and for various other reasons. In other cases, insurance against certain risks, including certain liabilities for environmental pollution, may not be available to us or to other companies within the industry. In addition, our insurance coverage may not continue to be available at economically feasible premiums, or at all. Any such event could have a material adverse effect on our business, operations or financial position.

Our pension and other post-retirement liabilities and the assets available to fund them could change materially.

We have substantial assets in defined benefit pension plans which arise through employer contributions and returns on investments made by the plans. The returns on investments are subject to fluctuations depending upon market conditions and we are responsible for funding any shortfall of pension assets compared to our pension obligations under these plans.

We also have certain obligations to current and former employees with respect to post-retirement benefits. The cost of providing these benefits can fluctuate and the fluctuations can be material.

Our liabilities under defined benefit pension plans and in respect of other post-retirement benefits are estimated based on actuarial and other assumptions. These assumptions may prove to be incorrect and may change over time, and the effect of these changes can be material.

Risks Related to the New Notes and our Indebtedness

Our significant indebtedness limits our flexibility and imposes restrictions on us, and a downturn in economic or industry conditions may materially affect our ability to meet our future financial commitments and liquidity needs.

As of June 30, 2020, we had debt, as determined consistent with IFRS and reflected on our consolidated balance sheet, of approximately C$5.431 billion (which does not include US$533 million of consolidated lease liabilities) and we had approximately US$4.92 billion of unused commitments under our committed bank credit facilities. Our ability to satisfy our debt obligations, including the New Notes, and our ability to refinance our indebtedness, will depend upon our future operating performance, which will be affected by prevailing economic conditions in the markets that we serve and financial, business and other factors, many of which are beyond our control. We may be unable to generate sufficient cash flow from operations and future borrowings or other financing may be unavailable in an amount sufficient to enable us to fund our future financial obligations or our other liquidity needs, including our obligations to repay our indebtedness, a significant amount of which will become due and payable prior to the maturity of the New Notes.

The amount and terms of our debt could have material consequences to our business, including, but not limited to:

24

Despite our current level of indebtedness, we may need to incur additional indebtedness in the future. The terms of our credit facilities, indentures and other agreements governing our indebtedness allow us to incur additional debt subject to certain limitations. If new debt is added to current debt levels, the risks described above could intensify. Furthermore, if future debt financing is not available to us when required or is not available on acceptable terms, we may be unable to grow our business, take advantage of business opportunities, respond to competitive pressure or refinance maturing debt, any of which could have a material adverse effect on our operating results and financial condition.

We may be unable to repay the New Notes when due or repurchase the New Notes when we are required to do so.

At final maturity of the New Notes or in the event of acceleration of the New Notes following an event of default, the entire outstanding principal amount of the New Notes will become due and payable. If we were unable to make the required payments or repurchases of the New Notes, it would constitute an event of default under the New Notes offered hereby and, as a result, under our credit facilities and other outstanding indebtedness. It is possible that we will not have sufficient funds at maturity or upon acceleration to make the required payments or repurchases of notes and other debt securities.

Some of our financing agreements contain financial and other covenants that, if breached by us, may require us to redeem, repay, repurchase or refinance our existing debt obligations prior to their scheduled maturity. Our ability to refinance such obligations may be restricted due to prevailing conditions in the capital markets, available liquidity and other factors.

We are party to a number of financing agreements, including our credit facilities and the indentures governing our various senior notes, including the New Notes offered hereby, which agreements, indentures and instruments contain financial and other covenants. If we were to breach the covenants contained in our financing agreements, we may be required to redeem, repay, repurchase or refinance our existing debt obligations prior to their scheduled maturity and our ability to do so may be restricted or limited by the prevailing conditions in the capital markets, available liquidity and other factors. If we are unable to refinance any of our debt obligations in such circumstances, our ability to make capital expenditures and our financial condition and cash flows could be adversely impacted. In addition, from time to time, new accounting rules, pronouncements and interpretations are enacted or promulgated which may require us, depending on the nature of such new accounting rules, pronouncements and interpretations, to reclassify or restate certain elements of our financing agreements and other debt instruments, which may in turn cause us to be in breach of the financial covenants contained in our financing agreements and other debt instruments.

We may not be able to finance a change of control offer required by our credit agreements and the indentures governing our various notes, including the New Notes offered hereby, because we may not have sufficient funds at the time of the change of control.

If we were to experience a change of control (as defined under the relevant indentures governing our various notes, including the New Notes offered hereby, and under our credit facilities), we would, under certain of the indentures, be required to make an offer to purchase all of the New Notes, debentures or other debt securities issued thereunder then outstanding at a specified premium to the principal amount (often 101%) plus accrued and

25

unpaid interest, if any, to the date of purchase, or to repay indebtedness under the relevant credit facilities. However, we may not have sufficient funds at the time of the change of control to make the required repurchase of the New Notes, debentures or other debt securities, or to make the required repayment of indebtedness. Our failure to offer to repurchase notes, debentures or other debt securities following a change of control would result in a default under their indentures, which could lead to a cross-default under our credit facilities and under the terms of our other indebtedness.

Our holding company structure may impact the ability of the holders of notes to receive payment on the New Notes.

We are a holding company with no material assets other than our equity interests in our subsidiaries and partnerships. As a result, our ability to repay our indebtedness, including the New Notes, is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Our subsidiaries do not have any obligation to pay amounts due on the New Notes or to make funds available for that purpose. In addition, our subsidiaries may not be able to, or be permitted to, make distributions to enable us to make payments in respect of our indebtedness, including the New Notes. Each of our subsidiaries is a distinct legal entity and, under certain circumstances, legal and contractual restrictions, as well as the financial condition and operating requirements of our subsidiaries, may limit our ability to obtain cash from our subsidiaries. Our right to participate in any distribution of our subsidiaries’ assets upon their liquidation, reorganization or insolvency would generally be subject to the prior claims of the subsidiaries’ creditors, including any trade creditors and preferred shareholders.

A financial failure by any entity in which we have an interest may hinder the payment of the New Notes.

A financial failure by any entity in which we have an interest could affect payment of the New Notes if a bankruptcy court were to “substantively consolidate” that entity with our subsidiaries and/or with us. If a bankruptcy court substantively consolidated an entity in which we have an interest with our subsidiaries and/or with us, the assets of each entity so consolidated would be subject to the claims of creditors of all entities so consolidated. This could expose our creditors, including holders of the New Notes, to potential dilution of the amount ultimately recoverable because of the larger creditor base.

The New Notes will be effectively subordinated to any of our secured indebtedness to the extent of the value of the collateral securing that indebtedness.

The New Notes will not be secured by any of our assets. As a result, the New Notes will be effectively subordinated to any of our existing and future secured obligations to the extent of the value of the collateral securing such obligations. At June 30, 2020, we had approximately US$438 million of secured debt (which does not include US$533 million of consolidated lease liabilities), all of which is secured debt of our subsidiaries. In addition, we may incur additional secured debt in the future. The effect of this effective subordination is that upon a default in payment on, or the acceleration of, any of our secured indebtedness, or in the event of bankruptcy, insolvency, liquidation, dissolution, reorganization or other insolvency proceeding in involving us, the proceeds from the sale of collateral securing our secured indebtedness will be available to pay obligations on the New Notes only after all secured debt has been paid in full. As a result, the holders of the New Notes may receive less, ratably, than the holders of secured debt in the event of a bankruptcy, insolvency, liquidation, dissolution, reorganization or other insolvency proceeding involving us.

The New Notes will be structurally subordinated to the indebtedness of our subsidiaries.

You will not have any claim as a creditor against our subsidiaries. As a result, all indebtedness and other liabilities, including trade payables, of our subsidiaries, whether secured or unsecured, must be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us in order for us to meet our obligations with respect to the New Notes. As of June 30, 2020, our subsidiaries had debt, as determined in accordance with IFRS, and trade payables of approximately US$1,191 million.

26

Federal and state fraudulent transfer laws permit a court to void the New Notes, and, if that occurs, you may not receive any payments on the New Notes.

The issuance of the New Notes may be subject to review under federal and state fraudulent transfer and conveyance statutes. While the relevant laws may vary from state to state, under such laws the payment of consideration will be a fraudulent conveyance if (1) we paid the consideration with the intent of hindering, delaying or defrauding creditors or (2) we received less than reasonably equivalent value or fair consideration in return for issuing the New Notes, and, in the case of (2) only, one of the following is also true:

If a court were to find that the issuance of the New Notes was a fraudulent conveyance, the court could void the payment obligations under the New Notes or further subordinate the New Notes to presently existing and future indebtedness of ours, or require the holders of the New Notes to repay any amounts received with respect to the New Notes. In the event of a finding that a fraudulent conveyance occurred, you may not receive any repayment on the New Notes. Further, the voidance of the New Notes could result in an event of default with respect to our and our subsidiaries’ other debt that could result in acceleration of that debt.

Generally, an entity would be considered insolvent if, at the time it incurred indebtedness:

We cannot be certain as to the standards a court would use to determine whether or not we were solvent at the relevant time, or regardless of the standard that a court uses, that the issuance of the New Notes would not be further subordinated to our other debt.

In the event that we become insolvent, insolvency proceedings will be governed by Canadian law and the laws of other jurisdictions.

We are incorporated in, and subject to, the laws of Canada. Canadian corporate insolvency laws, which are principally contained in the Companies’ Creditors Arrangement Act (the “CCAA”) and the Bankruptcy and Insolvency Act (the “BIA”) are different from the corporate insolvency or bankruptcy laws of the United States. In particular, proceedings under the CCAA, which provides for the potential re-organization of an insolvent company, differ significantly from Chapter 11 under the U.S. Bankruptcy Code. If we become insolvent, the treatment and ranking of the holders of the New Notes, other creditors and shareholders under Canadian law may be different than the treatment and ranking under the bankruptcy laws of the United States.

The New Notes may be challenged under applicable insolvency, or other laws, which could impair the enforceability of the New Notes.

Under corporate insolvency laws in Canada, a note could be voided. Our liability under the New Notes could be reduced to zero, if successfully challenged by a trustee in bankruptcy (a “Trustee”) under the provisions of the BIA, a court-appointed monitor (a “Monitor”) under the provisions of the CCAA or in some circumstances

27

by an affected creditor. In addition, various other orders could be made by a court in relation to the New Notes, such as a stay of proceedings preventing payments being made under the New Notes, and orders requiring the repayment of monies paid or providing for the discharge of debts.

Under Canadian law, if a Trustee or Monitor is appointed with respect to any Canadian company, the Trustee or Monitor would have the power to investigate the validity of past transactions such as the issuance of the New Notes, and may seek various court orders, including orders to have declared void certain transactions entered into prior to the commencement of the insolvency proceeding of such company and for the repayment of money. These transactions include transactions which:

There are varying periods before the commencement or deemed commencement of a company’s insolvency proceeding during which, if the company enters into a transaction of a type that is voidable, the transaction may be set aside as a result of a Trustee or Monitor seeking a court order. For example, a preference transaction entered into when the company is insolvent or which results in the company becoming insolvent, may be declared void if the company entered into it within the three-month period preceding the commencement of the company’s insolvency proceeding or, if the transaction was with a related entity, within a twelve-month period. Similarly, a conveyance of property for conspicuously less than fair market value could be voided if made to an unrelated entity within one year, or if made to a related entity within five years.

The test for whether a company is an “insolvent person” under the BIA and CCAA in this context is whether the relevant company is able to pay its obligations generally when they become due or whether the assets of the company, on fair valuation, are insufficient, or if disposed of at a fairly conducted sale under legal process would not be sufficient, to pay all of the obligations of the company due and accruing due.

Under Canadian law, a note given by a company may be set aside or subordinated on a number of grounds in addition to the voidable transactions described above, including pursuant to principles of equitable subordination.

In addition, under the laws of Canada, our other debts and liabilities, such as certain employee entitlements, pension liabilities or other amounts owed to taxing authorities and other government claimants, may rank ahead of claims under the New Notes in the event of insolvency or similar proceedings.

The issuance of the New Notes may be subject to review under Canadian provincial assignment and preference and fraudulent conveyance statutes. While the relevant laws may vary from province to province, under such laws, the making of a transfer or payment may be a fraudulent conveyance or a voidable assignment or preference under provincial law if: (i) the payment or transfer of property was made with the intent of defeating, hindering, delaying or defrauding creditors; and (ii) we were insolvent or rendered insolvent by reason of the incurrence of the indebtedness, or if we knew that we were on the eve of insolvency.

If a court were to find that the issuance of the New Notes was a fraudulent conveyance or a voidable preference under provincial law, the court could void the payment obligations under the New Notes or require the holders of the New Notes to repay any amounts received with respect to the New Notes. In the event of the court making a declaration that a fraudulent conveyance or voidable preference had occurred under provincial law, holders may not receive any repayment on the New Notes. Further, the declaration that the New Notes are void could result in an event of default with respect to our and our subsidiaries’ other debt that could result in acceleration of that debt.

In addition, there can be no assurance as to how the insolvency laws of the various jurisdictions in which we operate will be applied in relation to one another.

There is no public market for the New Notes, and we cannot assure you that a market for the New Notes will develop.

We do not intend to apply for a listing of the New Notes on any securities exchange or automated interdealer quotation system.

The New Notes will be a new class of securities for which there is no established public trading market, and no assurance can be given as to:

If such a market were to exist, the New Notes could trade at prices that may be higher or lower than their principal amount or purchase price, depending on many factors, including:

A lowering or withdrawal of the ratings assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital.

Any rating assigned to our debt securities could be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, future circumstances relating to the basis of the rating, such as adverse changes, so warrant. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the New Notes. Credit ratings are not recommendations to purchase, hold or sell the New Notes. Additionally, credit ratings may not reflect the potential effect of risks relating to the structure or marketing of the New Notes or other factors discussed in this prospectus on the value of the New Notes.

Any future lowering of our ratings likely would make it more difficult or more expensive for us to obtain additional debt financing. If any credit rating initially assigned to the New Notes is subsequently lowered or withdrawn for any reason, you may not be able to resell your notes without a discount.

The interests of major shareholders may conflict with the interests of the holders of the New Notes.

Temagami Mining Company Limited (“Temagami”) has informed us that as of February 26, 2020, it beneficially owned or exercised direction or control, directly or indirectly, over 4,300,000 of our Class A common shares (representing 55.37% of the Class A common shares outstanding) and 725,000 of our Class B subordinate voting shares (representing 0.13% of the Class B subordinate voting shares outstanding), which shares represent 32.7% of the total votes attached to the combined outstanding Class A common shares and

29

Class B subordinate voting shares. Although not a controlling interest per se, this is a significant voting interest. As with other shareholders, Temagami’s interests in our business, operations and financial condition from time to time may not be aligned with, or may conflict with, the interests of the holders of notes. So long as Temagami owns a significant amount of our outstanding common shares, it may have influence over our decisions.

Risks Related to the Exchange Offer

If you fail to exchange your Initial Notes, they will continue to be subject to transfer restrictions and may become less liquid.

Initial Notes that you do not tender or we do not accept will, following the exchange offer, continue to be subject to transfer restrictions, and you may not offer or sell them except pursuant to an exemption from, or in a transaction not subject to, the U.S. Securities Act and applicable state securities law. We will issue New Notes in exchange for the Initial Notes pursuant to the exchange offer only following the satisfaction of the procedures and conditions set forth in “Exchange Offer—Terms of the Exchange Offer—Conditions” and “Exchange Offer—Terms of the Exchange Offer—Procedures for Tendering.” These procedures and conditions include timely receipt by the exchange agent of such Initial Notes (or a confirmation of book-entry transfer) and of a properly completed and duly executed letter of transmittal (or an agent’s message from DTCC (as defined herein)).

Because we anticipate that most holders of Initial Notes will elect to exchange their Initial Notes, we expect that the liquidity of the market for any Initial Notes remaining after the completion of the exchange offer will be substantially limited. Any Initial Notes tendered and exchanged in the exchange offer will reduce the aggregate principal amount of the Initial Notes outstanding. Following the exchange offer, if you do not tender your Initial Notes you generally will not have any further registration rights, and your Initial Notes will continue to be subject to certain transfer restrictions. Accordingly, the liquidity of the market for the Initial Notes could be adversely affected.

Some persons who participate in the exchange offer must deliver a prospectus in connection with resales of the New Notes.

Based on interpretations of the staff of the SEC contained in Exxon Capital Holdings Corp., SEC no-action letter (April 13, 1988), Morgan Stanley & Co. Inc., SEC no-action letter (June 5, 1991) and Shearman & Sterling, SEC no-action letter (July 2, 1993), we believe that you may offer for resale, resell or otherwise transfer the New Notes without compliance with the registration and prospectus delivery requirements of the U.S. Securities Act. However, in some instances described in this prospectus under “Plan of Distribution,” you will remain obligated to comply with the registration and prospectus delivery requirements of the U.S. Securities Act to transfer your New Notes. In these cases, if you transfer any New Notes without delivering a prospectus meeting the requirements of the U.S. Securities Act or without an exemption from registration of your New Notes under the U.S. Securities Act, you may incur liability under the U.S. Securities Act. We do not and will not assume, or indemnify you against, this liability.
