TECK RECEIVES ENVIRONMENTAL ASSESSMENT CERTIFICATE FOR HIGHLAND VALLEY COPPER MINE LIFE EXTENSION

The B.C. government has issued an environmental assessment certificate for Teck Resources Ltd.'s proposed Highland Valley copper mine life extension project.

"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 chief executive officer. "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 continuing operations will support approximately 1,500 direct jobs and $500-million in annual gross domestic product. The HVC MLE would extend the life of Highland Valley copper to the mid-2040s.
