IMPERIAL REPORTS PRODUCTION UPDATE FOR 2023 THIRD QUARTER

Imperial Metals Corp. has released quarterly copper and gold production from Mount Polley and Red Chris mines. Imperial's production for the third quarter was 12,182,493 pounds copper and 14,335 ounces gold, of which 8,056,570 pounds copper and 11,321 ounces gold were produced at Mount Polley and 4,125,923 pounds copper and 3,014 ounces gold from Imperial's 30-per-cent share of Red Chris mine production. In the previous quarter 11,181,595 pounds copper and 14,289 ounces gold were produced, with 7,062,836 pounds copper and 10,185 ounces gold coming from Mount Polley and 4,118,759 pounds copper and 4,104 ounces gold coming from its 30-per-cent share of Red Chris mine production. Copper production for the quarter was up 9 per cent, largely from increased production at Mount Polley while gold production was virtually the same compared with the previous quarter with increased production at Mount Polley offsetting lower gold production at Red Chris.

Mount Polley metal production was up by 14.1 per cent for copper and 11.2 per cent for gold for this quarter due to slightly higher copper grades, and higher throughput. The throughput averaged 16,959 tonnes per day compared with 15,724 tonnes per day in the previous quarter; copper recovery was 79.5 per cent compared with 79.9 per cent in the first quarter and gold recovery was 70.1 per cent compared with 68.3 per cent in the previous period. Excellent metal recoveries continued to be achieved throughout the quarter despite additional throughput being restricted as the mill motor, which was damaged due to a lightning strike in the second quarter, was under repair until this month.

Red Chris copper and gold production (100 per cent) for the quarter was 13,753,075 pounds copper and 10,048 ounces gold, compared with 13,729,195 pounds copper and 13,680 ounces gold in the previous quarter. Gold production was 27 per cent lower than the prior period, primarily driven by lower gold head grade from the phase 7 ore source, which was in line with expectations.

The exploration program continued at Red Chris during the quarter with drilling completed west of the Main zone, in the Gully, and Far West zones as well as in the recently recognized White Rock Canyon targets. In addition to drilling, a program of geological mapping and geochemical sampling was completed across several regional targets.

Newcrest continued the development of the Block Cave during the quarter. As at Oct. 8, 2023, the exploration decline advanced to 3,580 metres and the conveyor decline advanced to 548 metres. The feasibility study also progressed, with financial evaluation of the project continuing during the quarter.
