Imperial Metals Corporation (TSX:III) reports copper and gold production for the first quarter 2026 from Red Chris mine. Red Chris metal production (100%) for the first quarter of 2026 was 18.982 million pounds copper and 20,108 ounces gold. Both copper and gold production were down compared with the first quarter of 2025, with copper production down 18% and gold production down 7%. Imperial’s 30% share of Red Chris mine production was 5.695 million pounds copper and 6,032 ounces gold.

Red Chris metal production (100%) for the first quarter of 2026 was 18.982 million pounds copper and 20,108 ounces gold, compared to 23.126 million pounds copper and 21,663 ounces gold produced during the same quarter of 2025. The decrease in copper production was a result of a 16% decrease in copper grade (0.52% versus 0.62%) with higher recovery and lower throughput. The decrease in gold production was a result of lower gold grade in the mill feed (0.49 g/t gold versus 0.54 g/t gold) and lower throughput, offset by better gold recovery (64.9% versus 60.5%) compared to the same quarter last year.

Both copper and gold production were however in line with the budgeted 2026 production, and the guidance for 2026 Red Chris production (100%) remains 60 – 66 million pounds of copper and 47,500 – 52,500 ounces of gold.
