Mount Milligan is a large-scale open-pit copper and gold mine operated by Thompson Creek Metals Company Inc., an indirect subsidiary of Centerra Gold Inc. The mine is located within the Omenica Mining Division in north-central British Columbia, Canada. The mining operation uses conventional truck-shovel, with ore processed through a concentrator with a 60,000 tonne per day capacity copper flotation processing plant, to produce a marketable concentrate containing copper, gold, and silver. The combined concentrate is pressure-filtered to a targeted moisture content of 8.5%, stockpiled, and then trucked to the rail loadout facility in Mackenzie. The concentrate is then railed to North Vancouver where it is loaded onto ships and sent to purchasers located around the Pacific Rim.

The Mount Milligan deposits are categorized as silica-saturated alkalic copper-gold porphyry deposits associated with alkaline monzodioritic-to-syenitic igneous rocks. Construction of the Mount Milligan mine began in June 2010, with commissioning of the mine beginning in August 2013. Commercial production at Mount Milligan was achieved on February 18, 2014.
