VANCOUVER, Nov. 22, 2013 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CUM) (the "Company" or "Copper Mountain") announces that one of the two ABB transformers powering the motors on Ball Mill #2 at the Copper Mountain mine has failed and has caused Ball Mill #2 to be out of service for a temporary period while repairs are made.  Mill throughput will be restricted by approximately 25% while the concentrator operates with just one Ball Mill. It is planned that the mill will be back to full production next week.

Spare coils are available and ABB have expedited crews to the mine to make the necessary repairs. As part of the original design plan for the concentrator, the two Ball mills and the SAG mill have identical motors and transformers that are interchangeable in the event of a component failure.  Because this failure involves just one transformer on Ball Mill #2, the concentrator is able to continue to operate with the SAG Mill and Ball Mill #1 at a reduced mill throughput. It is anticipated that production will be limited to approximately 1050 TPOH or about 25,000 TPD until repairs are completed.

Jim O'Rourke, President & CEO of Copper Mountain commented, "This transformer failure is a disappointing event for the operation at this time as our team has been making significant strides in improving tonnage through the SAG mill.  Production of copper for the month of October was on schedule at 6.5 million pounds and although this event will slightly impact metal production all resources are being applied to minimize the impact. This outage is not expected to affect our ability to achieve our guidance of 65 to 70 million pounds of copper for 2013".
