The operation is accessed by road from Fort St. James, at a distance of 85 km. The mining operation uses conventional trucks and electric shovels, with ore processed through a 60,000 tonne per day capacity copper flotation plant to produce a marketable concentrate containing copper, gold and silver. The concentrate is pressure-filtered, stockpiled and then trucked to the rail loadout facility in Mackenzie. The concentrate is then transported by rail via the Canadian National Railway approximately 1,254 km to North Vancouver, where it is loaded onto ships and sent to purchasers located around the Pacific Rim. Water for the operation is collected from surface run-off and stored in the tailings pond; it is supplemented by groundwater pumping and pumping from other surface water resources. Power is supplied by BC Hydro through a 92-km transmission line that is fed from the Peace River hydroelectricity generation facilities. Commercial production was achieved in February 2014, and the operation has a mine life based on ore reserves through 2033, with exploration potential that the Operator estimates will extend the mine life. ESG HIGHLIGHT AND SDG CONTR IBUTION: At the 2021 Mine Reclamation Symposium hosted by the British Columbia Technical and Research Committee on Reclamation, Centerra Gold, Inc. (“Centerra”) and Chu Cho Environmental were co-recipients of the Jake McDonald Annual Reclamation Award for their ongoing research into innovative techniques to solve reclamation, remediation and ecological restoration issues at the Mount Milligan Mine, and for their partnerships with local communities. We believe that Centerra’s actions to support economic empowerment through local employment and procurement opportunities, combined with its collaborative efforts with Indigenous business leaders to help solve reclamation challenges, contribute to SDG 15, Life on Land.
