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.

This slide discloses the results of economic analysis of mineral resources. 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.
C1 cash unit costs per pound is a non-GAAP ratio. See “Non-GAAP Financial Measures and Ratios” slides.

• Significant demand growth expected due to energy
transition to renewables
• Concentrate supply expected to peak in 2026, before
declining due to decreasing ore grades, protracted
permitting timelines, and underinvestment
• To address the long-term projected deficit will require
significant investment
• Mine production grew 7Mt in the last 20 years, mine
supply needs double that in less than 17 years
• Increasing costs will likely push price floor higher
‒ Current prices not moving projects forward
• Consensus forecasts suggest that at the low end for
2023 – 2024 forecasts, prices may start to trend

Copper Scrap is Part of the Long Term Solution
Lower prices are restricting short term scrap supply
Copper Scrap1 (kt)
• Scrap availability tends to fluctuate with copper
prices in the short term
• Copper scrap is 33%1 of total copper demand
and could rise to 40% by 2035
• Scrap availability improving as post-COVID
manufacturing and transportation recovers
• Over the next decade scrap availability may
increase, but trade flows are likely to change as
new secondary processing facilities are built
outside of China
• An improvement of 2% in global recycling rates
could provide up to 1.0Mt to global supply

• Projected roll out rates for EVs have
increased 37% in the last year
• Requirements for charging stations
expected to more than double by 2035
Wind
• Copper demand from wind power expected
to more than double by 2035
• Offshore wind could grow 7x (base case)
and >13x
Electrification
• Requirements for new electric grid
infrastructure to support higher electricity
output could add an additional 4Mt to
copper demand to meet IEA 1.5˚C
scenarios
Solar
• Copper solar growth from several
components including inverters, wire and
cable, transformers, solar trackers and
more
• By 2035: Solar demand could increase by
235kt under base case assumptions and by
1.1 Mt under an IEA 1.5˚C scenario

Copper Metal Outlook
• Global exchange stocks, lowest since 2005

• Stocks have fallen over 380kt since end Q2 2022
• Total global stock days are at 2.2 days of
consumption, down from long term average of 15
days
• New mine supply coming on starting in 2023 will
only partially offset lower demand growth
• Risks to supply increasing at same time as
concerns grow over demand growth
• Prior to H2, CRU estimated cathode market in

Zinc Outlook
Consumer demand pauses; decarbonization pushes ahead
Raw material supply increasing; smelters constrained
• Most European idled smelter
capacity has returned.
• North American capacity issues
in 2022 mostly resolved,
performing well.
• Global metal inventories starting
to recover. Still well below historic
levels, all metal stranded in Asia
• Spot premiums starting to fall
amid softening demand. Risk to
further smelter suspensions as
margins remain tight
• Decarbonization expected to
drive further zinc demand growth
even amid weakened
macroeconomic outlook
• Government and corporate
initiatives fuel support for
renewable infrastructure
• Wind energy, solar energy, all
supported by galv. steel
• IZA suggests additional 375kt of
demand from renewables by
2030
• European consumer market
headed for potential recession
• North American market resilient.
Inflation dampens housing market
and some consumer spending
but offset by strong automotive
sector
• EV transition driving significant
auto growth across multiple
markets
• Chinese demand recovery has
been softer than anticipated but
stimulus expected in H2
• Low zinc prices are putting mines
at risk of closure. ~1.5% global
supply suspended.
• New projects are advancing, but
shuddered mines risk delays to
project pipeline
• Chinese concentrate imports
remain high in 2023: Flat
domestic mine output keeps
market competitive for smelter
feed
• Mine cuts likely to be felt at
smelters within the next year.
Current stocks may keep zinc
price depressed through H1 2024

66
Zinc Mine Production Being Lost Under Low Prices1 (¢/lb)
Mine Disruptions in Copper Approach Critical Level
Mine output cuts to be felt in refined market
• After extensive destocking of zinc metal in Europe and
North America, weak demand in Asia has pushed zinc
prices down, forcing production cuts at mines
• 2023 has seen ~300 kt/y cut from annual mine capacity
‒ 75th percentile at risk with declining prices
‒ Recently-shuddered mines unlikely to restart, despite
remaining reserves
• Mine closures mean sufficient supply will not be available
post 2023 as smelter capacity grows
‒ Secondary material (i.e., zinc from recycled steel,
EAF dust) is not suitable for most smelters
• Up to 400 kt/y in new mine capacity coming online in near
term (<2 years) but still not enough to close gap
• Higher prices will be needed to encourage new mine
development

Zinc Concentrate Outlook
Zinc Mine Production and Demand1 (kt)
• Long term supply will lag demand
• Mines face declining production at higher costs
and lower grades from existing mines
• Exploration under investment will continue at
lower zinc prices
• Mine costs are also on the rise as consumables
and labour increases
• Recent incremental production has come from
higher cost or lower grade extensions, thus
increasing C1 and sustaining capital costs by
22% since 2014
• 75th percentile is the historical support level

Zinc Mine Supply Expected to Peak in 2025-2026
Global Zinc Mine Production1 (kt contained)
• Mine production projected to fall by ~1.0 Mt by
2030
‒ Represents a potential 2.0 Mt shortfall to
expected smelter capacity
‒ Production from established zinc mines only
increased by 1.5% since 20131
• Zinc concentrate supply is tightening again in the
short term, as smelters return to peak operating
and mine supply shows limited YOY growth
• Concentrate tightness expected to appear in late-
2024 to 2025, beyond 2024 additional production
will be required
• Recent (2022) record prices failed to move
significant production forward
‒ <0.5 Mt from <10 new projects committed

Chinese Concentrate Imports (kt)1
China’s Zinc Demand to Require Additional
Concentrate Imports
• China has continued to increase its smelter capacity to
decrease its reliance on refined imports
‒ Smelter capacity ~500 kt/y more in 2023 versus 2018
‒ No growth in mine output over the same period
‒ Additional 500 kt/y in net conc demand through 2027
• Zinc demand currently still strong due to:
‒ Infrastructure investment (new energy applications)
‒ New Energy Vehicles (NEVs), more zinc-intensive
due to need for more high-strength galvanized steel
o Production up 43% YoY in H1 20233
• Despite slowdown in 2022, Chinese refined imports
picking up again in 2023 up >600% (197kt through July)
‒ Demand remains strong in China despite real estate
slowdown

Asian LME Warehouses Rebuild to 2021 Levels1
Global Zinc Metal Outlook
Rising LME stock may keep price pain through 2024; mine output cuts too deep
• Rebuilding of inventory was expected following extensive
smelter disruptions in 2022
‒ European smelter cuts impacted up to 800 kt/y of
refined supply
‒ Maintenance issues at other smelters globally also
reduced refined output
‒ Ex-China refined supply fell 400 kt in 2022
• 135kt of LME inventories rebuilt in Singapore over six
months, similar to levels in April 2021
‒ Asian warehouses filling with Asian, Australian and
European brands of zinc
‒ Inventory levels remain well below historical norms
• Surplus market in 2023, manifested in rising inventory
levels already.
• Demand recovery through 2027 will force tighter raw
material supply due to mine closures which will force the
refined market back into deficit
Recovery and Tight Raw Material Will Eliminate Surplus in 20243

Zinc Concentrate Market Outlook
Upcoming deficits will require new mine supply
Concentrate Balances, excl. Uncommitted Projects1 (kt)
• Smelters idled in 2022 on high energy costs will
likely return by H2 2023
• Short term concentrate surpluses will create a
two-tiered market, based on quality
• Lack of investment and low metals stocks will
require additional zinc units post 2024
• Zinc-focused exploration investment has only
been 26% of copper-focused exploration
investment over the past 5 years2
• Few quality greenfield or advanced exploration
opportunities surfaced in the last 10 years
‒ Except Teck’s Teena discovery in Australia
and the Hermosa Pb-Zn project in Arizona

Zinc Metal Short Term Outlook
US Net Short Position in Zinc1 (kt)
• US produces less than 25% of its demand for zinc
• North America meets only ~80% of US demand
• Over the past decade, a shortfall of 150-275 kt/yr existed
beyond N.A. output and imports
• In 2012, there was >1.2 Mt of zinc metal in the US in LME
warehouses
• Today, US LME inventories are nil and Europe is no longer
in a position to support US deficits, keeping physical
premiums supported at higher than historical levels

• 60% of zinc concentrate demand from
galvanizing steel, which extends service life and
makes infrastructure more sustainable
• Decarbonization will be steel intensive
• Under an accelerated IEA 1.5˚C scenario
renewables will need to account for close to 10%
of end use demand, rising to 25% by 2050
• Demand for zinc in the energy transition could go
from 1.0Mt today to 4.7 Mt by 2050
• The IZA estimates that zinc use in wind
applications could rise to 66kt by 2030 and in
solar to 166kt
• The use of zinc in energy storage batteries could
rise to 150kt by 2030

June YTD 2019
• Wet weather, labour shortages, logistical challenges
and challenging geological conditions all contribute
• Seaborne supply:
‒ Investment in new mine projects slow as
Australian companies focus on divestitures
‒ Permitting and approvals face increased
scrutiny
• Steel prices are picking up though steel
demand recovers at a slow pace
• >70% of blast furnace (BF) capacity that
was idled in 2022 has been announced
to restart
• China crude steel production is up 15 Mt
YTD July, still up 49 Mt over YTD July
2019
• EAFs (electric arc furnaces) continue to
be impacted more than BFs
• China’s post-reopening recovery is
slower than expected due to the drag of
the property sector
