IMPERIAL REPORTS PRODUCTION UPDATE FOR 2024 FIRST QUARTER

Imperial Metals Corp. had quarterly copper and gold production from Mount Polley and Red Chris mines. Imperial's production was 12,353,000 pounds copper and 12,861 ounces gold, with 7,355,000 pounds copper and 10,009 ounces gold coming from Mount Polley, and 4,998,000 pounds copper and 2,852 ounces gold from its 30-per-cent share of Red Chris mine production.

Mount Polley metal production (100 per cent) for the first quarter of 2024 was 7,355,000 pounds copper and 10,009 ounces gold, compared with 6,678,000 pounds copper and 9,980 ounces gold produced during the first quarter of 2023.

Mill throughput was up 20.3 per cent, with 1,671,000 tonnes being treated compared with 1.39 million tonnes treated in the first quarter of 2023. Copper production in the first quarter 2024 was up by 10.1 per cent as a result of the increase in throughput, which offset lower grade and recovery compared with first-quarter 2023.

Tailings removal from the Springer pit is 84-per-cent complete and is expected to be completely removed by early May. Stripping for the phase 5 pushback of the Springer pit has begun and approximately 1.7 million tonnes of waste from this pushback was mined by the end of March, 2024.

Red Chris metal production (100 per cent) for the first quarter of 2024 was 16.66 million pounds copper and 9,507 ounces gold, compared with 11.59 million pounds copper and 10,496 ounces gold produced during the same quarter of 2023.

The 2024 first-quarter Red Chris copper production was up 44 per cent compared with the first quarter in 2023, and down 9 per cent for gold compared with the first quarter of 2023. The increase in copper production was a result of a 33-per-cent increase in copper grade (0.431 per cent versus 0.325 per cent) and an 8-per-cent increase in recovery (83.4 per cent versus 77.4 per cent). The drop in gold production in the first quarter was the result of lower gold grade, 0.263 gram per tonne (g/t) gold versus 0.311 g/t gold, being treated in the quarter compared with the same quarter last year.
