1. Second Quarter 2017 Results
July 27, 2017

2. Forward Looking Information
2
Both these slides and the accompanying oral presentation contain certain forward-looking statements within the meaning of the United States Private Securities
Litigation Reform Act of 1995 and forward-looking information within the meaning of the Securities Act (Ontario). Forward-looking statements can be identified
by the use of words such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or
“does not anticipate”, or “believes”, or variation of such words and phrases or state that certain actions, events or results “may”, “could”, “should”, “would”,
“might” or “will” be taken, occur or be achieved. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may
cause the actual results, performance or achievements of Teck to be materially different from any future results, performance or achievements expressed or
implied by the forward-looking statements.
The forward-looking statements in these slides and the oral presentation include estimates, forecasts, and statements as to management’s expectations with
respect to, among other matters, our dividend expectations, closing of the sale of Waneta Dam, sales, cost and production guidance for our various
commodities and operations, expectation that our realized coal sale price relative to prices assessments will be similar to what is has been relative to
negotiated quarterly benchmark, expected timing of first oil from Fort Hills, Fort Hills cost guidance and timing of discussed project milestones, the availability of
our credit facilities, anticipated pricing adjustments, our expectation that we will generate significant free cash flow, and demand and market outlook for
commodities. These forward-looking statements involve numerous assumptions, risks and uncertainties and actual results may vary materially.
These forward-looking statements involve numerous assumptions, risks and uncertainties and actual results may vary materially. These statements are based
on a number of assumptions, including, but not limited to, assumptions regarding general business and economic conditions, interest rates, the supply and
demand for, inventories of, and the level and volatility of prices of zinc, copper, coal and gold and other primary metals and minerals produced by Teck as well
as oil, natural gas and petroleum products, Teck’s costs of production and production and productivity levels, as well as those of its competitors, power prices,
market competition, the accuracy of Teck’s reserve estimates (including, with respect to size, grade and recoverability) and the geological, operational and
price assumptions on which these are based, our ongoing relations with our employees and partners and joint venturers, performance by customers and
counterparties of their contractual obligations, and the future operational and financial performance of the company generally. Our Fort Hills project
expectations also include assumptions that the project is built and operated according to our project development plan.
The foregoing list of assumptions is not exhaustive. Events or circumstances could cause actual results to differ materially. Factors that may cause actual
results to vary include, but are not limited to: adverse developments in business and economic conditions in the principal markets for Teck’s products, in credit
markets, or in the supply, demand, and prices for metals and other commodities to be produced, changes in interest and currency exchange rates, failure of
customers or counterparties to perform their contractual obligations, inaccurate geological or metallurgical assumptions (including with respect to the size,
grade and recoverability of mineral reserves and resources), changes in taxation regimes, legal disputes or unanticipated outcomes of legal proceedings,
unanticipated operational difficulties (including failure of plant, equipment or processes to operate in accordance with specifications or expectations, cost
escalation, unavailability of materials and equipment, government action or delays in the receipt of permits or government approvals, industrial disturbances or
other job action, and unanticipated events related to health, safety and environmental matters), and changes in general economic conditions or conditions in
the financial markets. The closing of the Waneta Dam sale depends on conditions precedent being satisfied, some of which are out of Teck’s control. Our Fort
Hills project is not controlled by us and construction and production schedules may be adjusted by our partners.
Certain of these risks are described in more detail in the annual information form of the company available at www.sedar.com and in public filings with the SEC.
The company does not assume the obligation to revise or update these forward-looking statements after the date of this document or to revise them to reflect
the occurrence of future unanticipated events, except as may be required under applicable securities laws.
