Copper Mountain Mining has announced a new life of mine plan for its 75% owned Copper Mountain Mine, located in southern British Columbia.
The plan, which includes a proposed mill expansion to 65,000 tonnes per day (ktpd), builds upon the 45ktpd mill expansion currently underway.
Copper Mountain said that in addition to increasing throughput, the 65ktpd expansion would reduce operating costs and energy consumption, improve flotation performance and de-bottleneck concentrate dewatering, allowing for more flexibility at high tonnage during high head grade periods.
According to the company, the project will not require any additional mining fleet, as the existing fleet already produces sufficient ore supply to feed the concentrator at the planned milling rates.
Copper Mountain’s President and CEO Gil Clausen said the mine life is estimated to be 21 years, including three years of processing stockpiled ore.
“The 65ktpd Expansion, which moves the Copper Mountain Mine to about a billion dollars of asset value, clearly underscores the mine’s quality, and our team’s ability to potentially grow reserves and value further,” Mr Clausen continued.
“This mill expansion study builds upon the growth projects that are already underway and illustrates the immense potential that the Copper Mountain Mine provides.
“In two years, we have more than doubled the mine life, grown the mine’s productive capacity, increased net asset value and significantly decreased cash costs.
“Following the completion of this 2020 Technical Report, we will further refine the capital estimates of this project in preparation for a development decision.”
