Copper production was up 26% from the 12.353 million pounds copper produced in the first quarter 2024 and gold production was up 7% from the 12,861 ounces gold produced in the first quarter 2024.

Mount Polley Mine

Mount Polley metal production for the second quarter of 2024 was 9.281 million pounds copper and 10,009 ounces gold, compared to 7.355 million pounds copper and 10,009 ounces gold produced during the first quarter of 2024.

Mill throughput in the second quarter 2024 was up 3%, with 1.714 million tonnes being treated compared with 1.671 million tonnes treated in the first quarter of 2024. Copper production in the second quarter of 2024 was up by 26% largely on higher grade of 0.294% copper versus 0.251% copper in the first quarter of 2024. Gold production was the same for each of the first and second quarters of 2024.

For the first six months of 2024, copper production was up 21% compared to the same period last year with 20% increase in throughput while gold production was down 1%, with lower gold grades and recovery offsetting the higher throughput.

Tailings removal from the Springer Pit was completed in May 2024. Stripping for Phase 5 pushback of the Springer Pit continued, with most of the non-acid generating rock from this pushback being delivered to the tailings dam for buttress construction.

Red Chris Mine

Red Chris production (100%) for the second quarter of 2024 was 20.731 million pounds copper and 12,531 ounces gold compared to 16.660 million pounds copper and 9,507 ounces gold during the first quarter of 2024.

In the second quarter of 2024, Red Chris copper production was up 24% compared to the first quarter of 2024. The increase in copper production was a result of an 8% increase in copper grade (0.47% vs 0.43%) and a 19% increase in throughput (27,357 tpd vs. 23,081 tpd). Gold production in the second quarter of 2024 was up 32% (12,531 oz vs 9,507 oz) from the first quarter of 2024 as result of the increased gold grades (0.30 g/t gold vs 0.26 g/t gold) and higher throughput.

For the first six months of 2024, copper production was up 48% compared to the same period last year on higher copper grades and gold production was down 9% on lower gold grades.
