Imperial Metals Soars on Mount Polley Drill Results
Vancouver, BC – May 22, 2025 – Shares of Imperial Metals Corporation (TSX: III) surged on Thursday following the release of promising drill results from its Mount Polley mine in British Columbia, renewing investor optimism in the company’s long-term resource potential.
The company announced that recent exploration drilling at Mount Polley has intercepted high-grade copper and gold mineralization at depths and extensions previously underexplored. Among the highlights was a drill hole that returned 92 meters grading 1.23% copper and 0.87 g/t gold, a result well above average grades historically produced from the site.
“These latest results confirm the presence of a substantial mineralized zone with excellent continuity and grade,” said Imperial Metals’ Vice President of Exploration, David Stewart. “It demonstrates that Mount Polley still holds significant untapped potential, even after years of operation.”
Mount Polley, which resumed limited operations in recent years following a tailings dam failure in 2014 and subsequent environmental remediation, has been under renewed scrutiny as Imperial seeks to re-establish full-scale production. The positive drill results are seen as a major step toward expanding the mine’s life and improving its overall economic viability.
The market responded swiftly to the news, with Imperial Metals’ stock rising more than 22% by mid-day, reaching its highest level in over a year. Trading volume spiked as investors digested the implications of the exploration data, which analysts say could lead to a significant revision of the mine’s resource estimate later this year.
“This is a game-changer for Imperial,” said Jennifer Liu, a mining analyst at Haywood Securities. “Not only does it bolster confidence in Mount Polley’s future, but it also sends a strong signal to the market that Imperial is back in growth mode.”
In addition to the Mount Polley developments, the company also reaffirmed its commitment to responsible mining and environmental stewardship, stating that any future expansion would be carried out with “enhanced safety and sustainability measures, guided by lessons from the past.”
Imperial Metals plans to continue its exploration program throughout the summer, with additional drill rigs being mobilized and updated resource modeling underway.
