DENVER, May 18, 2012 /CNW/ - Thompson Creek Metals Company Inc., a growing, diversified North American mining company (the "Company" or "Thompson Creek"), today reported that on May 15, 2012, a wall slough occurred in the Phase 7 mining area of the Thompson Creek mine.  The Company believes the slough resulted from water pressure behind the wall due to seasonal run-off.  There were no injuries or equipment damage and management believes that the event will not have a material impact on the current mine plan.  Management will continue to evaluate the potential impacts, if any, to the Company's 2012 production and cost guidance for the mine.
