Mulga Tank.
A nickel resource
at scale.
Western Mines is advancing a resource-defined nickel sulphide project in Western Australia. Phase 4 and 5 drilling is being incorporated into an updated Mineral Resource Estimate, while seismic and technical work help frame the next decisions.

A defined resource.
An evolving picture.
Mulga Tank has moved well beyond a first-pass exploration story. The company controls the Mulga Tank Ultramafic Complex and is using new drilling, geophysics and technical work to understand where the project can go next.

03 / WHAT THE WORK IS ASKINGFrom establishing scale
From establishing scale
to testing quality.
Recent programs seek to improve the definition of shallow mineralisation while testing higher-grade targets and the prospective basal contact. These are exploration and study objectives, not established mine economics.
Image the system
An EIS co-funded seismic survey is planned to help map the architecture and basal contact of the complex.
Test the next targets
Follow up shallow higher-grade intervals and continue diamond work on deeper basal sulphide targets.
Progress technical work
The company is working toward an initial scoping study. No completed project economics are assumed here.
6 OCTOBER 2026 UPDATE
Final Phase 5 RC assays reported broad nickel sulphide mineralisation in all seven reported holes. WMG said the updated resource would feed into scoping study work.

Technical evidence,
clearly accessible.
The Mulga Tank story rests on systematic RC and diamond drilling. WMG describes extensive disseminated nickel sulphide mineralisation and a deeper exploration model focused on the basal zones.
