VANCOUVER, July 28 /CNW/ - Copper Mountain Mining Corporation ("CMMC" or the "Company) is pleased to announce that it continues to optimize the Similco mine plan based on the latest resource estimate, as reported in the April 16, 2009 press release. The reserves and updated mine plan have been completed by Hatch Ltd. ("Hatch") and will be reported in a Technical Report that will be filed on SEDAR in August 2009 (the Technical Report).

Results of the Feasibility Study completed by Hatch Ltd. ("Hatch") in 2008 were reported in the July 28, 2008 press release and the corresponding Technical Report was filed on SEDAR. The primary changes to the current production plan include higher copper production in the initial years and an increased mine life, based on the optimized pit design using the most recent resource estimate. The mine plan is based on a conventional open pit mine with a 35,000 tonnes per day mill. The Similco Mine, a former producer, is designed to produce approximately 100 million pounds of copper per year in a copper concentrate with gold and silver credits. Production is scheduled to commence in mid-2011 and the project would create approximately 274 permanent jobs over a 17 year mine life with.

The Mineral Reserve is the part of the resource that is included in the open pit plan, as designed by Hatch, and is based on an economic cutoff grade of 0.15% Cu. The Proven and Probable Mineral Reserve totals 211.1 million tonnes averaging 0.36% Cu containing 1.7 billion lbs. of copper as summarized in the table below. The figures below include an allowance for dilution and ore loss.
