VANCOUVER, June 18, 2014 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CUM) (the "Company" or "Copper Mountain") announces that construction of the new permanent secondary crusher at the Copper Mountain mine located in southern British Columbia continues to move forward as planned and on schedule and budget. All major pieces of the crushing equipment have been delivered to site and substantial completion of the crusher building has been achieved. The lower bowl assembly, which is the largest component piece of the crusher weighing in at over 100 tonnes, has been safely lifted into place. This paved the way for the upper main frame of the crusher to be installed with the help of one of the mine's 240 ton haul trucks. (see photo next page). The existing one kilometer overland conveyor that transfers ore from the primary crusher to the mill feed stockpile has been successfully modified to accommodate the tie-in to the new secondary crusher. The installation of a new transfer chute was completed over a four day period without any interruption to the milling operation. This transfer chute is a critical component to the new system and is working well plus it will allow the current operation to continue with uninterrupted production for the balance of the secondary crusher construction period.

This crusher will be the largest cone crusher installed in western Canada and has the ability to crush the 6 inch rock from the primary crusher down to minus 2 inch in size. The new crushing facility is designed to operate at a rate of 3,000 tpoh and is designed to meet the high tonnage applications. The total cost of construction for the secondary crusher facility is estimated to be $40 million and construction is expected to be completed by mid-summer. Once installed, 100% of the mill feed will be sized to the 2 inch range, which will allow the mill to operate consistently at or above design capacity rates of 35,000 tpd.
