FIRST QUANTUM MINERALS SUSPENDS OPERATIONS AT ITS GUELB MOGHREIN MINE

First Quantum Minerals Ltd. (“First Quantum” or the “Company”, TSX Symbol “FM”, LSE Symbol “FQM”) today announced that it has temporarily suspended normal operations at its Guelb Moghrein copper-gold mine in Mauritania due to strike action by some unionized employees.

The Company has sought a negotiated resolution. While these efforts continue, steps are now being undertaken to further scale back management resources at site until a decision to restart normal operations is made.

The Company will provide further updates as warranted.
