This approval allows the Company to purchase up to 63,797,653 common shares of the Company (the "Common Shares") (representing 10% of the 735,397,977 issued and outstanding Common Shares as of December 4, 2019, minus those Common Shares beneficially owned, or over which control or direction is exercised by the Company, the senior officers and directors of the Company and every shareholder who owns or exercises control or direction over more than 10% of the outstanding Common Shares) over a period of twelve months commencing on December 9, 2019. The NCIB will expire no later than December 8, 2020.

All purchases made pursuant to the NCIB will be made through the facilities of the TSX or other alternative Canadian trading systems.

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.
