Zenith Minerals confirms lithium pegmatites at Split Rocks Project in WA

The chemical signature of the pegmatites resembles that of major lithium spodumene mines in WA.

Split Rocks is around 150 kilometres south of Southern Cross

Zenith Minerals Ltd (ASX:ZNC) has hit thick pegmatite bodies with potential lithium mineralisation in reverse circulation (RC) drilling at its Split Rocks Project along the Forrestania Greenstone Belt in Western Australia.

Preliminary 4-metre composite assay results from the Dulcie prospect indicate the lithium content is strongly anomalous, with one assay intercepting 80 metres at 353 ppm lithium with a peak value of 4 metres at 917 ppm.

The analysed lithium content increases to the north and at depth, providing a targets for follow-up testing.

Zenith tested a 950-metre long zone of pegmatites in the RC program, which had previously returned strong anomalous lithium results up to 2 metres at 0.12% lithium in shallow aircore holes.

The results confirm that the basal portion of the intersected pegmatite in the northernmost holes has a chemical signature like those of major lithium spodumene mines in WA, such as Greenbushes, Pilgangoora, Bald Hills and Mt Cattlin.

The Mt Holland lithium deposit, containing 189 million tonnes at 1.5% lithium and owned by Kidman Resources Ltd (ASX:KDR), is 40 kilometres north of Split Rocks and also shares a similar chemical signature.

First pass surface samples taken at Split Rocks, covering around 20% of Zenith’s tenements, have defined seven large and coherent lithium anomalies with variable levels of associated caesium, tantalum and rubidium.

These surround granite bodies that may be potential source rocks for lithium bearing pegmatites.

Three soil anomalies returned results up to 134 ppm, but field follow-up indicated little to no outcropping and will require drill testing.

Zenith is systematically exploring the Split Rocks project for both lithium and gold.

Large parts of the western portion of the project area are covered by thick, low lying scrub that has restricted past exploration activities.
