COURT RESERVES JUDGEMENT ON BOTH JUDICIAL REVIEW PETITION AND INJUNCTION APPLICATION RELATING TO MOUNT POLLEY TAILINGS STORAGE FACILITY

Further to Imperial Metals Corp.'s news release dated May 9, 2025, following a four-day hearing, the Supreme Court of British Columbia has reserved judgment on the judicial review petition and injunction application filed by the Xatsull First Nation that challenged two provincial decisions authorizing a four-metre raise of the tailings storage facility (TSF) embankment at the Mount Polley mine until the court issues its reasons for decision, expected on Aug. 6, 2025.

Mount Polley Mining Corp. (MPMC) is permitted to continue construction of the four-metre raise as planned and operations at the mine continue in accordance with the permits granted by the Ministry of Mining and Critical Minerals and the Environmental Assessment Office. In the interim, MPMC has provided a voluntary undertaking to refrain from depositing tailings that rely on the TSF raise until Aug. 7, 2025, to allow the court time to consider the matter.

The petition and injunction were heard together on June 24, 2025, to June 27, 2025. At the hearing, counsel for MPMC, Imperial's wholly owned subsidiary, and counsel for the Province of British Columbia argued the decisions are valid and were issued through the proper process with adequate consultation.

Imperial and MPMC are committed to transparent engagement with indigenous communities and environmental responsibility. Maintaining a meaningful relationship with Xatsull and Williams Lake first nations is important to the company, including supporting sustainable development through meaningful dialogue.

"We appreciate the court taking its time to carefully consider this matter and await its decision on the interlocutory injunction application and petition. We are committed to working collaboratively with Xatsull and other indigenous communities to address their concerns," stated Brian Kynoch, president of Imperial. "Our goal is to ensure that all operations at Mount Polley mine are conducted in an environmentally responsible manner that respects the rights of indigenous peoples."

Imperial and MPMC will continue to work with provincial regulators and indigenous communities to ensure future actions align with regulatory requirements and community expectations.
