Mount Milligan is a large open-pit gold and copper mine located approximately 155 kilometres northwest of Prince George, British Columbia. In 2025, the mine produced 147,581 ounces of gold and 50.5 million pounds of copper. The current mine plan extends to 2045, and exploration is looking for additional gold and copper that could support operations beyond that date.
