Zenith Minerals has announced that it has begun drilling at its Yilmia Lithium Project, located south of Coolgardie in Western Australia.
The Yilmia Lithium Project is inferred to contain an 8km long greenstone package that is considered highly prospective for lithium pegmatites on the southern margin of the Woolgangie Monzogranite.
An initial program of approximately 3,000m to 6,000m of aircore drilling on 800m spaced lines is underway to test the 8km long lithium target zone.
A strong aeromagnetic anomaly is coincident with ultramafic and mafic rock units that are shown on government geological maps, further east of the Yilmia project area. That same aeromagnetic anomaly extends through the northern portion of the project area, under soil cover, indicating that the greenstone belt likely extends further west through the Yilmia project tenure.
Furthermore, the presence of greenstone within the Yilmia project area, is also supported by a historic soil sampling program and a historical electromagnetic geophysical survey that were conducted as part of nickel exploration in the area of interest to Zenith. There is no rock outcrop within the target zone, so drill testing is required.
Drill holes (YLAC001 – 015) on the first line completed at the eastern margin of the project area, intersected pegmatites up to 20m thick, within a greenstone host rock package comprising ultramafic and mafic lithologies. All assays are awaited.
Zenith Minerals Managing Director, Michael Clifford, said that the project was added to the company’s lithium portfolio in May 2023.
“We infer from geophysical and geochemical data an 8km long greenstone rock sequence, wrapping around the southern margin of the Woolgangie Monzogranite, that we consider prospective for lithium pegmatites,” Mr Clifford said.
“The recent Kangaroo Hills lithium pegmatite discovery by Future Battery Metals is in a similar setting on the western margin of the Woolgangie Monzogranite, some 13km to the northwest of our target zone.”
