Halls Creek Project
COB has completed a comprehensive desktop review of Halls Creek and identified development options to be advanced via a Scoping Study—forecast for completion in or around June 2025.
- The Review included an extensive compilation of historical metallurgical testwork demonstrating that high metal recoveries are achievable.
- COB intends to advance flowsheet development using two separate processing pathways, with treatment of:
- Oxide / transition mineralisation via acid leaching (heap leach)
- Sulphide mineralisation via flotation
Kwinana Cobalt Refinery
- With 80% of the detailed plant engineering completed, the Kwinana Cobalt Refinery is advancing through the final stages to support a Final Investment Decision.
- Permitting has progressed through a public consultation period and is being assessed by the Western Australian Department of Water and Environmental Regulation.
- COB was pleased to host our potential partner, Iwatani, at the Broken Hill Technology Development Centre in early March.
