Red Chris Mine Receives Major Regulatory Authorizations for Block Cave Project

Executive Summary

• The Province of British Columbia has granted key authorizations, including an amended Environmental Assessment Certificate and Mines Act authorization, to transition the Red Chris mine from open pit to a block cave operation.
• Secured through a consent-based framework with the Tahltan Nation, the approvals extend the mine's operational life into the mid-2040s and serve as a critical precursor to a final investment decision expected later in 2026.
• A Definitive Feasibility Study led by operator Newmont Corporation is currently underway, with the block cave project projected to create over 1,800 construction jobs, sustain ~1,500 peak operating roles, and increase Canada’s copper production by approximately 15%.
