LUNDIN MINING ANNOUNCES DECLARATION OF REGULAR DIVIDEND

Lundin Mining Corp. has declared a regular quarterly dividend of nine cents per share, payable to shareholders of record at the close of business on May 31, 2024. This dividend qualifies as an eligible dividend for Canadian income tax purposes. The declaration, timing, amount and payment of future dividends remain at the discretion of the board of directors.

Starting May 27, 2024, the Toronto Stock Exchange will shorten the settlement cycle to trade date plus one business day (T+1). As a result, the first day of trading without dividend will be May 31, 2024, for shares traded on TSX. For shares traded on Nasdaq Stockholm, the ex dividend date will be May 30, 2024.

Dividends on shares traded on TSX will be paid in Canadian dollars on June 19, 2024. Dividends on shares traded on Nasdaq Stockholm will be paid in Swedish kronor in accordance with Euroclear principles on June 25, 2024. To execute the payment of the dividend, a temporary administrative cross-border transfer closure will be applied by Euroclear from May 29, 2024, up to and including May 31, 2024, during which period shares of the company cannot be transferred between TSX and Nasdaq Stockholm.
