Imperial Reports Mount Polley Production Update for 2025 Third Quarter

On October 20, 2025, Imperial Metals reported third-quarter 2025 production for its Mount Polley mine. The company produced 7.66 million pounds of copper and 9,285 ounces of gold. More significantly, Imperial raised its full-year 2025 production guidance for Mount Polley. The new copper target is approximately 30 million pounds, exceeding the high end of the original 25-27 million pound range. Gold production is now expected to be at the high end of its original 35,000-40,000 ounce target range.

This news is materially positive. While Q3 production of 7.66 million pounds of copper is down from 9.82 million pounds in Q3 2024, this was anticipated. The company had previously guided in its February 20, 2025 release that the higher-grade Phase 4 of the Springer Pit would be mined out by Q3 2025, with lower-grade ore from the Phase 5 pushback being processed in the latter part of the year.

The key takeaway is the significant increase in full-year guidance. By the end of Q3, Mount Polley had already produced 26.06 million pounds of copper year-to-date (8.90M in Q1, 9.50M in Q2, 7.66M in Q3). This means the mine has already met the midpoint of its original annual guidance in just nine months. The new target of 30 million pounds requires only 3.94 million pounds in Q4, which appears conservative and highly achievable, even with the planned lower grades.

This guidance raise demonstrates significant operational outperformance in the first half of the year and provides a clear positive revision to expected revenue and earnings for fiscal 2025. This strong operational report card reinforces a series of positive developments for the company in 2025, including a favorable court ruling on its tailings facility, receipt of a life-of-mine permit amendment, and the successful conversion of $47 million of debt into equity.

Imperial Metals Corporation is a Canadian mining company focused on the extraction and development of base and precious metals. Its principal assets are: 1. Mount Polley Mine (100% owned): A producing open-pit copper/gold mine in British Columbia. This is the company's primary operational focus. Recent developments include successful exploration in the C2 zone and a new discovery 4km north of the mill, along with permitting to extend the mine life. 2. Red Chris Mine (30% interest): A large producing open-pit copper/gold mine in British Columbia, operated by joint-venture partner Newmont (70%). The key future value driver is the development of a large, high-grade underground block cave mine beneath the current pit. 3. Huckleberry Mine (100% owned): A past-producing copper mine in British Columbia, currently on care and maintenance.
