The price that Lundin Mining will pay for Common Shares in open market transactions will be the market price at the time of purchase.

The actual number of Common Shares that may be purchased and the timing of such purchases will be determined by the Company. Decisions regarding purchases will be based on market conditions, share price, best use of available cash, and other factors. Any Common Shares that are purchased under the NCIB will be cancelled.

Forward-looking information includes, but is not limited to, statements with respect to Lundin Mining's proposed normal course issuer bid and the number of Common Shares that may be purchased under the normal course issuer bid. Words such as "will", "intends", "expects", "believe", "anticipate", "possible", "if", "will be", "may" and "schedule", or variations of these terms or similar terminology or statements that certain actions, events or results "could" occur or be achieved are intended to identify such forward-looking information. Although the Company believes that the expectations reflected in the forward-looking information contained herein are reasonable, these statements by their nature involve risks and uncertainties, and are not guarantees of future performance. Forward-looking information is based on a number of assumptions, and subject to a variety of risks and uncertainties which could cause actual events or results to differ from those reflected in the forward-looking statements. Risks include but are not limited to the market price of the Common Shares being too high to ensure that purchases benefit the Company and its shareholders, as well as additional risks disclosed in filings made by the Company with Canadian securities regulatory authorities. There can be no assurance that the Common Shares will, from time to time, trade below their value or that the Company will complete purchases of Common Shares pursuant to the NCIB. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company disclaims any intention or obligation to update or revise any forward-looking statements or to explain any material difference between subsequent actual events and such forward- looking statements, except to the extent required by applicable law.
