Copper Mountain reports Ball Mill transformer interruption

Web Site:
VANCOUVER, Nov. 22, 2013 /CNW/ - 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".
