Yellowhead Copper Project

Trekor Metals Limited is proposing the construction, operation, and closure of a new open-pit copper mine located about 150 kilometres northeast of Kamloops, British Columbia. The Yellowhead Copper Project has been designed with a production capacity of 90,000 tonnes of ore per day (up to 32 million tonnes per year) over a 25-year mine life. The project, which would also produce gold and silver, includes a new mill, an approximately 110 kilometre transmission line that would connect to an existing B.C. Hydro substation near 100 Mile House, and a rail load-out facility at an existing site at Vavenby.

British Columbia's Environmental Assessment Office is collaborating with the Impact Assessment Agency of Canada as part of the federal impact assessment of the project. For more information on the EAO's process, please visit EPIC.engage.

 

Please note that the proponent of this project was previously known as Taseko Mines Limited.

Latest update

August 13, 2026 — The Minister of the Environment, Climate Change and Nature approved the Government of British Columbia's (B.C.) request to substitute the provincial review process for the federal impact assessment process. This means B.C.'s Environmental Assessment Office (EAO) will conduct the project’s impact assessment on behalf of the Impact Assessment Agency of Canada.
