Teck Resources has initiated a comprehensive review of its operations, including a detailed action plan for the Quebrada Blanca (QB) mine, aimed at enhancing performance and delivery.

The review, launched in August, is expected to conclude by October 2025, with updates to be communicated no later than Teck’s third-quarter results.

The QB copper mine in northern Chile comprises an open pit, concentrator plant and tailings facility.

Teck holds a 60% interest in the mine, with Sumitomo Metal Mining and Sumitomo Corporation holding a collective 30% and Codelco with a 10% non-funding interest.

The QB action plan will address slow sand drainage issues affecting development and production at the tailings management facility (TMF).

Near-term priorities include mechanically raising the tailings dam wall and increasing crest height, improving sand drainage times and refining sand placement techniques.

A respected industry leader has been onboarded as special advisor to the CEO to expedite TMF development and operational performance.

Teck is also focused on strengthening operational readiness and resilience across QB operations.

This involves confirming a practical mining strategy and enhancing efficiency throughout the entire operation, including the mining site, processing facility and shipping port.

Furthermore, Teck is evaluating its planning, forecasting and reconciliation procedures with a view to enhancing them to bolster operational preparedness and the quality of decision-making.

The company has decided to postpone the approval of significant expansion projects until the QB site reaches a consistent state of operations and has met its scale-up objectives.

In related news, Teck received approval in July to construct a life extension project at its Highland Valley Copper mine in British Columbia, Canada, extending the mine’s life from 2028 to 2046, following the sanctioning of the project by the company’s board.
