Global Metals and Mining Conference 2 Caution Regarding Forward-Looking Statements Both these slides and the accompanying oral presentation contain certain forward-looking information and forward-looking statements as defined in applicable securities laws (collectively referred to as forward-looking statements). These statements relate to future events or our future performance. All statements other than statements of historical fact are forward-looking statements. The use of any of the words “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “potential”, “should”, “believe” and similar expressions is intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. These statements speak only as of the date of this presentation. These forward-looking statements include, but are not limited to, statements concerning: forecast production; forecast operating costs, unit costs, capital costs and other costs; sales forecasts; all guidance included in this presentation, including production guidance, sale and unit cost guidance, capital expenditure guidance, water treatment guidance, and the sensitivities thereto; our strategies, objectives and goals; future accounting treatment for QB2; our portfolio of copper growth options and expectations for our copper projects, including San Nicolas, NewRange, QBME, Zafranal, Galore Creek, NuevaUnion and Schaft Creek, including expectations related to the submission and receipt of regulatory approvals, timing for completion of prefeasibility and feasibility studies, costs and timing related to construction and commissioning and expectations relating to production levels, capital and operating costs, mine life, strip ratios, C1 cash costs and further expansions; expectations regarding mine life extensions for HVC, Antamina and Red Dog, including expectations relating to timing for regulatory approvals and feasibility studies, production rates, life of mine extensions, required capital projects and ability to utilize existing infrastructure; expectations and planned activities relating to our zinc development options; expectation that we have the potential to be a top 10 copper producer and that QB2 is expected to double our consolidated copper production at full capacity; expectations regarding water treatment in the Elk Valley, including the statement that we expect further reductions as treatment increases; our expectations regarding our QB2 project; our expectations relating to the demand for and supply of copper, zinc, steelmaking coal and other products and commodities that we produce and sell; our expectations relating to future prices and price volatility for copper, zinc, steelmaking coal and other products and commodities that we produce and sell; our expectations relating to future operating costs for our operations and those of our competitors; and all other statements relating to the outlook of the markets for copper, zinc, steelmaking coal and other products and commodities that we produce and sell. Actual results and developments are likely to differ, and may differ materially, from those expressed or implied by the forward-looking statements contained in this presentation. Such statements are based on a number of assumptions that may prove to be incorrect, including, but not limited to, assumptions regarding: general business and economic conditions; commodity and power prices; assumption that QB2 becomes fully producing within expected timeframes; the supply and demand for, deliveries of, and the level and volatility of prices of copper, zinc, steelmaking coal, and our other metals and minerals, as well as oil, natural gas and other petroleum products; the timing of the receipt of permits and other regulatory and governmental approvals for our development projects and other operations, including mine extensions; our costs of production and production and productivity levels, as well as those of our competitors; availability of water and power resources; credit market conditions and conditions in financial markets generally; our ability to procure equipment and operating supplies and services in sufficient quantities on a timely basis; availability of qualified employees and contractors for our operations, including our new developments and our ability to attract and retain skilled employees; the satisfactory negotiation of collective agreements with unionized employees; the impact of changes in Canadian-U.S. dollar exchange rates, Canadian dollar-Chilean Peso exchange rates and other foreign exchange rates on our costs and results; the accuracy of mineral and steelmaking coal reserve and resource estimates (including with respect to size, grade and recoverability) and the geological, operational and price assumptions on which these are based; tax benefits and tax rates; our ongoing relations with employees and with our business and joint venture partners; the impact of climate change and climate change initiatives on markets and operations; and the impact of geopolitical events on mining operations and global markets. Assumptions regarding QB2 include current project assumptions and assumptions contained in the final feasibility study, as well as there being no further unexpected material and negative impact to the various contractors, suppliers and subcontractors for the QB2 project relating to COVID-19 or otherwise that would impair their ability to provide goods and services as anticipated. Expectations regarding our operations are based on numerous assumptions regarding the operations. Statements concerning future production costs or volumes are based on numerous assumptions of management regarding operating matters and on assumptions that demand for products develops as anticipated; that customers and other counterparties perform their contractual obligations; that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, COVID-19, interruption in transportation or utilities, or adverse weather conditions; and that there are no material unanticipated variations in the cost of energy or supplies. Assumptions regarding water quality management in the Elk Valley include assumptions that additional treatment will be effective at scale, that the technology and facilities operate as expected and that required permits will be obtained. The foregoing list of important factors and assumptions is not exhaustive. Other events or circumstances could cause our actual results to differ materially from those estimated or projected and expressed in, or implied by, our forward-looking statements. See also the risks and assumptions discussed under “Risk Factors” in our 2022 Annual Information Form and in subsequent filings, which can be found under our profile on SEDAR+ (www.sedarplus.com) and on EDGAR (www.sec.gov). Except as required by law, we undertake no obligation to update publicly or otherwise revise any forward-looking statements or the foregoing list of factors, whether as a result of new information or future events or otherwise. Inherent in forward-looking statements are risks and uncertainties beyond our ability to predict or control, including risks that may affect our operating or capital plans; that are generally encountered in the permitting and development of mineral properties such as unusual or unexpected geological formations; associated with the COVID-19 pandemic; associated with unanticipated metallurgical difficulties; relating to delays associated with permit appeals or other regulatory processes, ground control problems, adverse weather conditions or process upsets and equipment malfunctions; associated with any damage to our reputation; associated with labour disturbances and availability of skilled labour; associated with fluctuations in the market prices of our principal commodities; associated with changes to the tax and royalty regimes in which we operate; created through competition for mining and oil and gas properties; associated with lack of access to capital or to markets; associated with mineral reserve and resource estimates; posed by fluctuations in exchange rates and interest rates, as well as general economic conditions; associated with changes to our credit ratings; associated with our material financing arrangements and our covenants thereunder; associated with climate change, environmental compliance, changes in environmental legislation and regulation, and changes to our reclamation obligations; associated with procurement of goods and services for our business, projects and operations; associated with non-performance by contractual counterparties; associated with potential disputes with partners and co-owners; associated with operations in foreign countries; associated with information technology; and risks associated with tax reassessments and legal proceedings. Scientific and technical information in this presentation and related appendices was reviewed and approved by Rodrigo Alves Marinho, P.Geo., an employee of Teck and a Qualified Person under National Instrument 43-101.

Mineral resources that are not mineral reserves and do not have demonstrated economic viability. Projections for Galore Creek, Mesaba and Schaft Creek include inferred resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Inferred resources are subject to greater uncertainty than measured or indicated resources and it cannot be assumed that they will be successfully upgraded to measured and indicated through further drilling.

Supplemental Information

  • 1. Global Metals and Mining Conference Supplemental Information September 6, 2023
  • 2. Global Metals and Mining Conference 2 Caution Regarding Forward-Looking Statements Both these slides and the accompanying oral presentation contain certain forward-looking information and forward-looking statements as defined in applicable securities laws (collectively referred to as forward-looking statements). These statements relate to future events or our future performance. All statements other than statements of historical fact are forward-looking statements. The use of any of the words “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “potential”, “should”, “believe” and similar expressions is intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. These statements speak only as of the date of this presentation. These forward-looking statements include, but are not limited to, statements concerning: forecast production; forecast operating costs, unit costs, capital costs and other costs; sales forecasts; all guidance included in this presentation, including production guidance, sale and unit cost guidance, capital expenditure guidance, water treatment guidance, and the sensitivities thereto; our strategies, objectives and goals; future accounting treatment for QB2; our portfolio of copper growth options and expectations for our copper projects, including San Nicolas, NewRange, QBME, Zafranal, Galore Creek, NuevaUnion and Schaft Creek, including expectations related to the submission and receipt of regulatory approvals, timing for completion of prefeasibility and feasibility studies, costs and timing related to construction and commissioning and expectations relating to production levels, capital and operating costs, mine life, strip ratios, C1 cash costs and further expansions; expectations regarding mine life extensions for HVC, Antamina and Red Dog, including expectations relating to timing for regulatory approvals and feasibility studies, production rates, life of mine extensions, required capital projects and ability to utilize existing infrastructure; expectations and planned activities relating to our zinc development options; expectation that we have the potential to be a top 10 copper producer and that QB2 is expected to double our consolidated copper production at full capacity; expectations regarding water treatment in the Elk Valley, including the statement that we expect further reductions as treatment increases; our expectations regarding our QB2 project; our expectations relating to the demand for and supply of copper, zinc, steelmaking coal and other products and commodities that we produce and sell; our expectations relating to future prices and price volatility for copper, zinc, steelmaking coal and other products and commodities that we produce and sell; our expectations relating to future operating costs for our operations and those of our competitors; and all other statements relating to the outlook of the markets for copper, zinc, steelmaking coal and other products and commodities that we produce and sell. Actual results and developments are likely to differ, and may differ materially, from those expressed or implied by the forward-looking statements contained in this presentation. Such statements are based on a number of assumptions that may prove to be incorrect, including, but not limited to, assumptions regarding: general business and economic conditions; commodity and power prices; assumption that QB2 becomes fully producing within expected timeframes; the supply and demand for, deliveries of, and the level and volatility of prices of copper, zinc, steelmaking coal, and our other metals and minerals, as well as oil, natural gas and other petroleum products; the timing of the receipt of permits and other regulatory and governmental approvals for our development projects and other operations, including mine extensions; our costs of production and production and productivity levels, as well as those of our competitors; availability of water and power resources; credit market conditions and conditions in financial markets generally; our ability to procure equipment and operating supplies and services in sufficient quantities on a timely basis; availability of qualified employees and contractors for our operations, including our new developments and our ability to attract and retain skilled employees; the satisfactory negotiation of collective agreements with unionized employees; the impact of changes in Canadian-U.S. dollar exchange rates, Canadian dollar-Chilean Peso exchange rates and other foreign exchange rates on our costs and results; the accuracy of mineral and steelmaking coal reserve and resource estimates (including with respect to size, grade and recoverability) and the geological, operational and price assumptions on which these are based; tax benefits and tax rates; our ongoing relations with employees and with our business and joint venture partners; the impact of climate change and climate change initiatives on markets and operations; and the impact of geopolitical events on mining operations and global markets. Assumptions regarding QB2 include current project assumptions and assumptions contained in the final feasibility study, as well as there being no further unexpected material and negative impact to the various contractors, suppliers and subcontractors for the QB2 project relating to COVID-19 or otherwise that would impair their ability to provide goods and services as anticipated. Expectations regarding our operations are based on numerous assumptions regarding the operations. Statements concerning future production costs or volumes are based on numerous assumptions of management regarding operating matters and on assumptions that demand for products develops as anticipated; that customers and other counterparties perform their contractual obligations; that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, COVID-19, interruption in transportation or utilities, or adverse weather conditions; and that there are no material unanticipated variations in the cost of energy or supplies. Assumptions regarding water quality management in the Elk Valley include assumptions that additional treatment will be effective at scale, that the technology and facilities operate as expected and that required permits will be obtained. The foregoing list of important factors and assumptions is not exhaustive. Other events or circumstances could cause our actual results to differ materially from those estimated or projected and expressed in, or implied by, our forward-looking statements. See also the risks and assumptions discussed under “Risk Factors” in our 2022 Annual Information Form and in subsequent filings, which can be found under our profile on SEDAR+ (www.sedarplus.com) and on EDGAR (www.sec.gov). Except as required by law, we undertake no obligation to update publicly or otherwise revise any forward-looking statements or the foregoing list of factors, whether as a result of new information or future events or otherwise. Inherent in forward-looking statements are risks and uncertainties beyond our ability to predict or control, including risks that may affect our operating or capital plans; that are generally encountered in the permitting and development of mineral properties such as unusual or unexpected geological formations; associated with the COVID-19 pandemic; associated with unanticipated metallurgical difficulties; relating to delays associated with permit appeals or other regulatory processes, ground control problems, adverse weather conditions or process upsets and equipment malfunctions; associated with any damage to our reputation; associated with labour disturbances and availability of skilled labour; associated with fluctuations in the market prices of our principal commodities; associated with changes to the tax and royalty regimes in which we operate; created through competition for mining and oil and gas properties; associated with lack of access to capital or to markets; associated with mineral reserve and resource estimates; posed by fluctuations in exchange rates and interest rates, as well as general economic conditions; associated with changes to our credit ratings; associated with our material financing arrangements and our covenants thereunder; associated with climate change, environmental compliance, changes in environmental legislation and regulation, and changes to our reclamation obligations; associated with procurement of goods and services for our business, projects and operations; associated with non-performance by contractual counterparties; associated with potential disputes with partners and co-owners; associated with operations in foreign countries; associated with information technology; and risks associated with tax reassessments and legal proceedings. Scientific and technical information in this presentation and related appendices was reviewed and approved by Rodrigo Alves Marinho, P.Geo., an employee of Teck and a Qualified Person under National Instrument 43-101.

Mineral resources that are not mineral reserves and do not have demonstrated economic viability. Projections for Galore Creek, Mesaba and Schaft Creek include inferred resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Inferred resources are subject to greater uncertainty than measured or indicated resources and it cannot be assumed that they will be successfully upgraded to measured and indicated through further drilling.
