Teck Receives Environmental Assessment Certificate for

Highland Valley Copper Mine Life Extension

Vancouver, B.C. – Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) today announced that the B.C. Government has issued an Environmental Assessment Certificate for the proposed Highland Valley Copper Mine Life Extension project (“HVC MLE”).

“This positive decision by the Government of B.C. will support extending the life of Canada’s largest copper mine, strengthening the North America critical minerals supply chain and contributing to jobs and economic activity,” said Jonathan Price, Teck President and CEO. “This is an important step forward that positions the project for a final construction sanction decision in the near term. I want to thank Indigenous Governments and the Province of B.C. for their thoughtful assessment of HVC MLE, and local communities, employees and all stakeholders for their engagement and feedback.”

Site preparation work is expected to start shortly along with work to secure additional required permits, with a final construction sanction decision by Teck’s Board of Directors expected in the third quarter of 2025.

HVC MLE is expected to create about 2,900 jobs during the construction phase of the project. After construction, Highland Valley Copper’s ongoing operations will support approximately 1,500 direct jobs and $500 million in annual GDP. The HVC MLE would extend the life of Highland Valley Copper to the mid-2040s.
