Summit has started field work at its rare earths and lithium assets in Western Australia’s Gascoyne region to identify and confirm targets for follow-up exploration.

Prospecting and outcrop sampling of identified REE-pegmatite and lithium targets is being carried out at the Morrissey project – adjacent to Red Dirt Metals’ Malinda lithium project where historical drilling had returned average grades of about 1.5% lithium oxide over intervals of between 1m and 5m.

This work includes assessing the geology of the prospects, such as the rare earth element-bearing pegmatite at Morrissey (E09/2482) and circular features coincident with magnetic highs at Lyndon (E04/2435).

Summit Minerals (ASX:SUM) has also procured satellite imagery and is working through historical data to guide and enhance its exploration efforts.

“The rare element-bearing pegmatites, which crop out within the southern Morrissey tenement, are associated with the southern margin of the Ti Tree Shear Zone,” managing director Jonathan King said.

“The pegmatites are related to tourmaline-bearing granites of the Thirty-Three Supersuite, which also hosts numerous lithium-bearing pegmatites in the immediate environment around the tenement.”

More exploration

Separately, the company remains on track to start drilling at the Stallion REE project in the state.

While originally targeted for uranium mineralisation, the same historical drilling which defined the uranium resource also intersected REE enrichment in the granitic bedrock underlying the paleochannels which form the exploration focus at the Stallion project.

Summit’s 16-hole proof of concept drill program will test the palaeochannel and “hot granites” for REE mineralisation.
