TORONTO, ONTARIO--(Marketwire - April 7, 2010) - Inmet Mining Corporation ("Inmet") (TSX:IMN) confirmed today that the Ok Tedi mine has been subjected to an illegal work action by employees who are members of the Ok Tedi Mining and Allied Workers Union (OTMAWU).

The action was initiated on April 1, 2010. Ok Tedi's management has been advised by the OTMAWU executive that the reasons for the work action principally relate to concerns regarding distributions under an employee retention bonus arrangement that is not part of Ok Tedi's industrial agreement with the OTMAWU.

Ok Tedi has called in representatives of the Papua New Guinea Department of Labour and Industrial Relations (DLIR) to facilitate a resolution in accordance with the industrial agreement and applicable laws. The DLIR has indicated to Ok Tedi and the OTMAWU that the strike action is unlawful and that employees participating in the work action should return to work. Discussions between Ok Tedi's management, the OTMAWU and DLIR representatives are continuing but it is not possible at this time to estimate the potential length of the work action.

Inmet estimates that its 2010 copper production will be reduced by 80 tonnes and 2010 gold production will be reduced by 300 ounces for each day the work action continues. Inmet's share of lost production to date is equivalent to approximately 0.4 percent of our forecast 2010 copper production and 1 percent of our forecast 2010 gold production.
