THE DRILL SERGEANT: Lithium Australia (ASX: LIT) reported further assay results from THE maiden RC drilling program underway at the company’s Youanmi project in Western Australia.
Lithium Australia released the results saying they included widths of high-grade lithium mineralisation from the campaign that has been designed to test down-dip extensions of outcropping lithium-bearing pegmatites.
Highlights of the drilling results include:
3 metres at 1.68 per cent lithium oxide (Li2O) from 32m;
3m at 1.27 per cent Li2O from 2m;
4m at 1.61 per cent Li2O from 21m;
5m at 1.54 per cent Li2O from 62m;
4m at 1.26 per cent Li2O from 2m; and
6m at 1.61 per cent Li2O from 22m, including 1m at 4.14 per cent Li2O from 22m.
Lithium Australia said the drilling had confirmed mineralisation over 2.5 kilometres of strike, with assays reporting widths of high-grade lepidolite (lithium mica) mineralisation hosted in LCT pegmatites.
Multiple stacked pegmatites have been intercepted in RC drill fences along this strike.
The drilling has also demonstrated that the pegmatites dip at shallow angles (20-30°) towards the east.
Mineralisation remains open down dip and along strike and further drill testing will be required to determine the extent of the mineralised system.
“These results from our maiden drill program – which confirm significant lithium mineralisation at Youanmi – are most encouraging,” Lithium Australia managing director Adrian Griffin said in the company’s announcement to the Australian Securities Exchange.
“The lithium is hosted in lepidolite, a lithium mica ideally suited to processing via our proprietary SiLeach technology.
“Initial results suggest Youanmi could provide critical local feedstock for Lithium Australia’s lithium-cathode and battery business units.”
