The project has competitive funding through Exploration Incentive Scheme grants, signaling strong external support for the campaign.

Nickel sulphide deposits are increasingly valued for battery-grade material, and a successful seismic campaign could boost Mulga Tank’s strategic value by providing clear deep-target insights.

The program plans 100 line kilometres of data from 65 kilometres of active 2D seismic lines spaced 1 km apart, plus 35 kilometres of receiver-only lines at 500 m spacing to create a pseudo-3D seismic cube imaging depths beyond 2,000 metres.

The seismic program at Mulga Tank will cover about 35 square kilometres, aiming to image the deep architecture and identify basal contacts, feeder zones, and thick, high-grade massive sulfide accumulations within the Minigwal Greenstone Belt.

Western Mines is expanding around the Yilgarn Craton and has partnered with Magnium Australia to monetise overburden at Mulga Tank for magnesite feedstock, with XRD results showing magnesite up to 48% in the upper dunite layer.

The program seeks to refine 3D targeting of Perseverance-style nickel sulphide deposits and unlock the belt-wide geological understanding by imaging the 3D architecture and basal massive sulfide accumulations.

Mulga Tank is the flagship project in Western Mines’ portfolio, which also includes Jasper Hill, Fraser Range, Mt Narryer, and Youanmi prospects.

Seismic results will be integrated with existing 3D magnetic and gravity data to build a richer geological model, potentially illuminating magma pathways and de-risking future drilling.

Western Mines has secured the maximum A$250,000 Exploration Incentive Scheme grant to fund the seismic campaign at Mulga Tank, located on the eastern margin of the Yilgarn Craton, about 150–200 kilometres northeast of Kalgoorlie.

Under the EIS terms, the grant covers 50% of the seismic survey costs, with work expected to commence mid-year.

Mulga Tank already hosts a 5.3-million-tonne contained nickel resource with long-running ultramafic and sulfide mineralisation, and deeper drilling is refining the geological model.

The seismic study is slated to begin mid-year as a pivotal push to unlock deeper, higher-grade nickel sulfide potential and create potential value for shareholders.
