Installation Of A Permanent SAG Mill Pre-Crusher
VANCOUVER - Jim O'Rourke, President and CEO of Copper Mountain Mining, reported although SAG Mill throughput has challenged us longer than we anticipated following the start-up period, we are confident that recently implemented modifications will provide short term improvements while the longer term solutions are implemented. We are cash flow positive and we will be continuing to improve the operation at the Copper Mountain mine as we increase the amount of minus 2 inch ore in the SAG Mill feed that will allow us to meet our production goals".
O'Rourke continued, "Looking forward, management's efforts are fully focused on optimizing the mill operations which include finalizing the work required to advance the installation of a permanent secondary crushing at the mine site. Production scale tests completed with pre-crushed ore to the SAG Mill have confirmed that by pre-crushing 100% of the ore to minus two inches the concentrator can achieve throughput rates above the designed capacity of 35,000 tpd. The Copper Mountain board of directors have approved the installation of a permanent SAG mill pre crusher and management is working with the Company's partner and lenders to obtain their agreements to move forward expeditiously"

Mill improvements were achieved during the quarter, in spite of the mill transformer loss time incident in mid-May that was fully repaired by early June, a full week ahead of schedule. The repaired transformer had all three sets of coils replaced and was fully inspected and certified as new prior to being returned to operation with a one year warranty. The mine exited the quarter on a positive note with the mill availability averaging 92.3% and copper production of 6.1 million pounds for the month of June.
