VANCOUVER, Jan. 15, 2014 /PRNewswire/ - Copper Mountain Mining Corporation (TSX: CUM) (the "Company" or "Copper Mountain") announces production results for the year ended December 2013 from the Copper Mountain mine located in southern British Columbia.
In 2013 the mine produced 66.2 million pounds of copper, 21.6 thousand ounces of gold, and 320.4 thousand ounces of silver. The mill averaged 87.8% operating time for the year and a total of 10.1 million tonnes of ore was milled at an average grade of 0.35 % Copper. The mill exited the year on a positive note with a throughput rate averaging 32,767 tpd for the month of December, a significant improvement over an average daily throughput rate of 26,000 tpd achieved during the 2012 year.
Improvements in mill throughput are attributable to the short term secondary crushing strategies which included increased powder factor in the mine and the installation of portable crushing plants ahead of the SAG mill. The combination of these activities is designed to create approximately 12,000 tpd of minus two inch ore feed for the SAG mill. Mill tonnage from these short term strategies in December averaged about 10,000 tpd or 30 percent of the mill feed being crushed to an average size of minus two inch. These short term measures have had positive results towards increasing mill throughput and activities are progressing to further increase mill throughput to 35,000 tpd by installing a permanent crusher to crush 100 percent of the mill feed to the 2 inch range.
The mine exited the quarter on a very positive note with a mill availability of 94.7% and copper production of 6.8 million pounds for the month of December. Mine production for the quarter ended December 31, 2013 was 18.6 million pounds of copper, 4,300 ounces of gold, and 105,800 ounces of silver, which is the highest production quarter since the mine commenced operations, despite having a transformer interruption during the quarter. The 4th quarter's production numbers were based on a recovery of 85% and an ore head grade of 0.375% Copper.
Mining activities continued from both the Pit 2 and Pit 3 areas and averaged approximately 166,000 tonnes per day. During the 2013 year a total of 56.7 million tonnes of material was mined, including 16.6 million tonnes of ore and 40.1 million tonnes of waste. The projected life of mine strip ratio is 2 to 1 but higher in the early years.

In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lea...
