Kwinana cobalt refinery progress

Cobalt Blue Holdings has formalised a feedstock agreement with Glencore to supply cobalt hydroxide for processing at the Kwinana refinery. This development is regarded as a significant milestone in advancing the refinery’s operational framework towards project readiness.

Halls Creek project scoping study

Silver resource identification

Subsequent evaluations have identified a substantial quantity of silver within the heap leach material at Halls Creek. This discovery provides scope for additional revenue streams alongside the primary copper and zinc output.

Minor metals contribution

Cobalt presence has also been confirmed in the San Diego deposit within the Halls Creek project area. Assessment is ongoing to integrate the recovery of minor metals, including cobalt and silver, into the overall project strategy.

Exploration initiatives

The company has identified three priority exploration targets in the Horse Creek area. Planned exploration includes infill drilling at San Diego North to verify possible resource extensions and evaluate the scope for a larger-scale operation.

Operational outlook
