Mill throughput for 2018 averaged 29,228 t/d and annual production was 60.4 million lb. of copper and 41,935 oz. of gold. Those numbers represent 97% of revised targets. This year the mine is to produce between 72 million and 76 million lb. of copper and 36,000 to 38,000 oz. of gold.

Fourth quarter production at Mount Polley was 3.18 million lb. of copper (up 22% from Q3) and 7,983 oz. of gold (up 3%). Mill throughput for the full year was16,975 t/d and annual output was 15.0 million lb. of copper and 37,120 oz. of gold.
