Imperial Reports Production Update for Red Chris Mine 2026 Second Quarter

Imperial Metals Corporation ("Imperial") (TSX:III,OTC:IPMLF) reports copper and gold production for the second quarter 2026 from Red Chris mine. Red Chris metal production (100%) for the second quarter of 2026 was 17.924 million pounds copper and 14,591 ounces gold. Both copper and gold production were down compared with the second quarter of 2025, with copper production down 24% and gold production down 36%. Imperial's 30% share of Red Chris mine production was 5.377 million pounds copper and 4,377 ounces gold.

Red Chris metal production (100%) for the second quarter of 2026 was 17.924 million pounds copper and 14,591 ounces gold, compared to 23.479 million pounds copper and 22,624 ounces gold produced during the same quarter of 2025. The decrease in copper production was a result of an 18% decrease in copper grade (0.45% versus 0.55%) with higher recovery and lower throughput. The decrease in gold production was a result of lower gold grade in the mill feed (0.35 g/t gold versus 0.49 g/t gold) and lower throughput, with similar gold recovery (59.4% versus 60.0%) compared to the same quarter last year.

Both copper and gold production remain on track to achieve 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.

The Red Chris feasibility study for a block cave expansion operation is advancing. The key permits are in hand with approval from both the Province of British Columbia and Tahltan First Nation. Completion of the feasibility study and, subject to the study outcomes, joint venture approval are expected in the second half of 2026.
