Judicial Review Petition Dismissed, Mount Polley to Continue Constructing TSF Raise
Vancouver | August 6, 2025 | Imperial Metals Corporation (the “Company” or “Imperial”) (TSX:III) The Supreme
Court of British Columbia today dismissed the application of the Xatśūll First Nation (“Xatśūll“) for an injunction
and judicial review of two provincial approvals authorizing construction of a four-metre lift on the tailings storage
facility (“TSF”) at the Mount Polley Mine (“Mount Polley”).
The Court found the decisions of the two provincial authorities allowing Mount Polley to construct the TSF lift
were reasonable and were made fairly, and that the Government sufficiently consulted with the Xatśūll before
making those decisions. The Court’s decision cited the extensive consultation record and actions taken in support
of Xatśūll’s review of the approvals.
Imperial and Mount Polley are committed to transparent engagement with Indigenous communities and
environmental responsibility. Maintaining a meaningful relationship with Xat śūll and Williams Lake First Nation
is important to the Company, including supporting sustainable development through meaningful dialogue.
Mount Polley Mine employs over 390 employees, making it a significant economic driver in the region.
Although the mine can continue to construct the TSF raise and may now deposit tailings that rely on that raise,
without receipt of our pending Mines permit amendment which allows Mount Polley to continue to mine, the
mine may again be put in jeopardy of significantly revising operational plans or ceasing operation if the Mines
permit amendment process is not expedited.
“We support and hold up the Court’s decision to dismiss the petition,” said Willie Sellars, Chief of the Williams
Lake First Nation (WLFN). "Mount Polley is a vital part of our regional economy, offering stable jobs and
contributing to programs that benefi t both WLFN members and the wider community. This outcome brings
certainty for our region and local businesses, and we look forward to the province continuing to support the
mine’s operations through timely permit approvals."
“There are significant challenges facing project advancement in British Columbia today. W ell-considered
decisions made by expert regulatory authorities following extensive consultations are frequently contested, at
great expense, increasing risk to projects through permitting delays and causing uncertainty for operators and
their employees and con tractors. We hope that today’s decision helps to reduce this risk and uncertainty,
especially for our workforce and their families. In the meantime, we will continue to follow regulatory processes
and respectfully engage with Williams Lake First Nation and Xatśūll First Nation, as we have in the past.” said
Brian Kynoch, President of Imperial.
