Inmet to Waive Shareholder Rights Plan

TORONTO, CANADA--(Marketwire - Feb. 19, 2013) - Inmet Mining Corporation ("Inmet" or the "Company") (TSX:IMN) announced today that its Board of Directors has decided to waive the application of its Shareholder Rights Plan (the "Rights Plan"), effective as of 3:00 pm ET on February 27, 2013. As such, the Ontario Securities Commission (the "OSC") hearing scheduled for February 25, 2013 to address the application by First Quantum Minerals Ltd. ("First Quantum") to cease trade the Rights Plan will no longer be required, and such notice will be provided to the OSC. Inmet has taken this action because the February 27, 2013 expiry date of the First Quantum unsolicited offer provides sufficient time for the full review and potential execution of all strategic alternatives being evaluated by the Inmet Board and its Special Committee. Inmet will provide shareholders with further information regarding its strategic alternatives as appropriate and prior to the expiry of the First Quantum offer.

The Inmet Board continues to recommend that Inmet shareholders REJECT the First Quantum offer and do not tender their shares. Shareholders who have already tendered their shares and wish to withdraw shares should contact their broker to withdraw their shares as soon as possible. Shareholders who have questions or require any assistance are asked to contact Inmet's information agent, Laurel Hill Advisory Group, at +1 877 452 7184.
