## Caution on Forward-Looking Information 

This document contains certain forward-looking information and forward-looking statements as defined in applicable securities laws. All statements other than statements of historical fact are forward-looking statements. These forward-looking statements, principally under the heading “Outlook”, but also elsewhere in this document, include estimates, forecasts and statements as to management’s expectations with respect to, among other things, mine life, anticipated production at our business units and individual operations, costs at our business units and individual operations, our expectation that we will meet our production guidance, sales volume and selling prices for our products (including settlement of coal contracts with customers), plans and expectations for our development projects, including resulting increases in forecast operating costs and costs of product sold, expected production, expected progress, costs and outcomes of our various projects and investments, including, but not limited to, those described in the discussions of our operations, the sensitivity of our profit to changes in commodity prices and exchange rates, the effect of potential production disruptions, the effect of currency exchange rates, our expectations for the general market for our commodities, future trends for the company, increased coal and copper production as a result of our expansion plans, results of our mill modernization program at Highland Valley Copper, reduced operating costs as a result of our restructuring plan at Quebrada Blanca, timing of the re-filing of the SEIA for the Quebrada Blanca Phase 2 project, our estimates of the effect of measures to manage selenium discharges and costs related thereto, the timing of permit approval, production and anticipated production levels from the Quintette mine, timing and results of the Neptune Bulk Terminals capacity expansions, timing of operation of our new acid plant at Trail Operations, the statements under the heading “Energy” regarding timing of sanction, production permitting decisions, timing of final supplemental information requests on our Frontier project and our responses to the review process thereto, anticipated capital expenditures and demand and market outlook for commodities. 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, the supply and demand for, deliveries of, and the level and volatility of prices of zinc, copper and coal and other primary metals and minerals as well as oil, and related products, the timing of the receipt of regulatory and governmental approvals for our development projects and other operations, our costs of production and production and productivity levels, as well as those of our competitors, power prices, continuing availability of water and power resources for our operations, market competition, the accuracy of our reserve estimates (including with respect to size, grade and recoverability) and the geological, operational and price assumptions on which these are based, conditions in financial markets, the future financial performance of the company, our ability to attract and retain skilled staff, our ability to procure equipment and operating supplies, positive results from the studies on our expansion projects, our coal and other product inventories, our ability to secure adequate transportation for our products, our ability to obtain permits for our operations and expansions, and our ongoing relations with our employees and business partners and joint venturers. Statements concerning timing of the re-filing of our SEIA for the Quebrada Blanca Phase 2 project are based on assumption of our ability to revise our application in response to comments in the time projected. Our selenium management plans are based on the assumptions, and subject to the factors, described under “Selenium Management”. The foregoing list of assumptions is not exhaustive. Events or circumstances could cause actual results to vary materially. 

Factors that may cause actual results to vary materially include, but are not limited to, changes in commodity and power prices, changes in market demand for our products, changes in interest and currency exchange rates, acts of foreign governments and the outcome of legal proceedings, inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral reserves and resources), 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 government approvals, changes in tax or royalty rates, industrial disturbances or other job action, adverse weather conditions and unanticipated events related to health, safety and environmental matters), union labour disputes, political risk, social unrest, failure of customers or counterparties to perform their contractual obligations, changes in our credit ratings, unanticipated increases in costs to construct our development projects, difficulty in obtaining permits, inability to address concerns regarding permits or environmental impact assessments, and changes or further deterioration in general economic conditions. Our Fort Hills project is not controlled by us and construction, sanction and production schedules may be adjusted by our partner. 

Statements concerning future production costs or volumes, and the sensitivity of the company’s profit to changes in commodity prices and exchange rates, 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, interruption in transportation or utilities, adverse weather conditions, and that there are no material unanticipated variations in the cost of energy or supplies. 

We assume no obligation to update forward-looking statements except as required under securities laws. Further information concerning risks and uncertainties associated with these forward-looking statements and our business can be found in our Annual Information Form for the year ended December 31, 2012, filed on SEDAR and on EDGAR under cover of Form 40-F.
