About Royal Gold Governance Our People Our Operators and Communities ESG Stewardship Appendices 15 2023 INVESTMENT STEWARDSHIP REPORT ROYAL GOLD MOUNT MILLIGAN, CENTERRA GOLD British Columbia, Canada | 2023 Revenue: $158,167,000 Construction of the Mount Milligan mine began in June 2010, with commissioning of the mine beginning in August 2013 and the achievement of commercial production in February 2014. The mining operation uses a conventional truck-and-shovel fleet, with ore processed through a 60,000-tonne per day flotation processing plant, to produce a concentrate containing copper, gold and silver. The concentrate is trucked to the rail loadout facility in Mackenzie and railed 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 pumping groundwater and 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 2035. The Operator is completing a preliminary economic assessment to review the potential to extend the mine life.
