The Scoping Study reflects a staged mining and processing operation to minimise start-up capital requirements and prioritise early cash flow.
In July 2026, we launched a metallurgical testwork program that could unlock silver as a significant new revenue stream alongside copper and zinc. Results will feed into an updated Scoping Study targeting completion in Q4 2026, with a Pre-Feasibility Study to follow.
Key outcomes of the Halls Creek Scoping Study (100% basis)
Nominal production rates estimation
Stage 1
Onedin Open Pit and Heap Leach
A two-stage open pit operation at Onedin, supplying oxide and transition feed to a heap leach facility located at Onedin for production of copper metal and zinc sulphate monohydrate via solvent extraction and electrowinning / crystallisation.
Stage 2
Sandiego Underground & Concentrator
An underground mining operation at Sandiego, delivering transition and primary feed to a concentrator to produce separate copper and zinc concentrates.
