There are currently eight diamond drill rigs turning at Red Chris. Imperial holds a 30% interest in the mine and Australia’s Newcrest Mining purchased the balance in 2019 and became the operator. The mine produced 88.3 million lb. of copper and 73,787 oz. of gold in 2020. A pre-feasibility study is underway on a potential underground block cave mine; it is due mid-year.
