VANCOUVER, April 1 /CNW/ - Copper Mountain Mining Corporation (TSX: CUM) (the "Company" or "Copper Mountain") is pleased to announce that the Company has received the anticipated amendment to its Mines Act Permit M-29 (the "Permit") from the Province of British Columbia for its Copper-Gold open pit mining Project (the "Project") near Princeton BC. Receipt of the amendment approval followed a comprehensive and detailed review of the Project led by the Mining and Minerals Division of the BC Ministry of Energy, Mines and Petroleum Resources.

Receipt of the Permit amendment is a key step in advancing the Copper Mountain Project. The amended permit approves the mine plan and reclamation program and authorizes the Company to proceed with the construction and operation of the mine. Work to date has focused on the pouring of concrete for the concentrator building foundations which is now complete. Steel for the concentrator building is being assembled on site and with this permit approval, erection of the steel will proceed to have the building prepared for the installation of processing equipment. Major mobile equipment is being received on site with the delivery of two Komatsu D375 dozers in preparation for preproduction mining activities later this summer. The Company anticipates having half of the mobile mining fleet assembled and ready for preproduction mining by the end of August 2010. To date the Company has incurred a total of $298 million in spent and committed expenditures out of a planned $438 million on the project. There are currently 99 construction people at site and this is expected to increase to 200 once steel erection begins. The Company has added some construction photos to the Company's web page for interested investors.

The overall schedule of the project has remained unchanged with preproduction mining expected to start later this summer, while construction is expected to be completed by April 2011 and full production planned by June 2011 at the rate of 35,000 TPD.

Mr. Jim O'Rourke, President and CEO, stated, "All aspects of the project are advancing as planned and we are confident that we will achieve our target of full production in June 2011."
