purchase exemption) on the TSX under the NCIB are limited to a maximum of 517, 131 Common Shares, which

represents 25% of the average daily trading volume of 2,068,525 Common Shares on the TSX for the six months

ended November 30, 2019. 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 ava ilable cash, and other factors. Any Common Shares that are purchased under the NCIB will be

cancelled.

Under the Company’s current NCIB that commenced on December 7, 2018 and expires on December 6, 2019,
