Imperial Metals Corporation (the "Company" or "Imperial") (TSX:III,OTC:IPMLF) reports quarterly copper and gold production from the 100% owned Mount Polley mine. Imperial's third quarter production from Mount Polley was 7.655 million pounds copper and 9,285 ounces gold.
Mount Polley Mine - Production
Mount Polley metal production for the third quarter of 2025 was 7.655 million pounds copper and 9,285 ounces gold, compared to 9.822 million pounds copper and 9,527 ounces gold produced during the comparative quarter of 2024.
Mill throughput in the third quarter 2025 was up 5%, with 1.780 million tonnes being treated compared with 1.694 million tonnes treated in the third quarter of 2024. Copper and gold production was lower in the third quarter of 2025 versus the third quarter of 2024. The reduction in metal production reflects the lower grades, and lower copper recovery, offset somewhat by the higher throughput.
For the first nine months of 2025, an increase in throughput, similar copper and gold grades and recoveries resulted in slightly lower copper production and 4.8% higher gold production compared to the same period last year.

Phase 4 pushback of the Springer pit generated 41% of the ore in the third quarter. Stripping of the Phase 5 pushback continues and produced 51% of the ore in the period. Approximately 1.0 million tonnes of Non-Acid Generating "NAG" waste was hauled to the Tailings Storage Facility.
The 2025 production targets for Mount Polley were 25 - 27 million pounds copper and 35,000 - 40,000 ounces gold. Copper production for the year is now targeted to be about 30 million pounds, exceeding the high end of the original 2025 target range. Gold production for the fourth quarter is expected to be similar to the previous quarters of 2025, and we expect to produce about 40,000 ounces of gold for 2025, the high end of the 2025 target for gold.
