The Province of British Columbia in Canada has approved a permit amendment for Imperial Metals, allowing the extension of mining activities at the Mount Polley copper and gold mine.

The expansion at Mount Polley, located in south-central British Columbia, will enable pit development and the enlargement of rock-storage areas, all within the existing mine site footprint.

This development will prolong the operational life of the mine in accordance with the submitted mine plan amendment application.

The decision was consented to by both the Minister of Mining and Critical Minerals and the Minister of Environment and Parks.

The decision to expand Mount Polley followed a joint review process that included an evaluation of technical reports, coordination with regulatory agencies and consultations with First Nations representatives.

This review was conducted to ensure that the expansion meets British Columbia's standards for environmental protection and public safety.

Imperial Metals president Brian Kynoch said: “Receiving this permit is good news for Imperial, our workers, the local community and our First Nations partners. We will be able to continue to provide good jobs and economic opportunities for the region.

“We will also continue to develop our exploration and mine planning to look for opportunities for further extension of the mine life. As always, we will follow regulatory processes and respectfully engage with Williams Lake First Nation and Xatśūll First Nation.”

Imperial Metals is an exploration, mine development and operating company. Its assets include full ownership of the Mount Polley and Huckleberry mines, along with a 30% stake in the Red Chris mine.

Additionally, the company’s portfolio includes 23 greenfield exploration properties across British Columbia.

In July, three individuals were trapped underground at the Red Chris mine following two separate “fall of ground” incidents.
