Aurumin Ltd (ASX:AUN) has identified lithium mineralisation at the Mt Palmer Project in Western Australia, encountering wide intersections of lithium-caesium-tantalum (LCT) style pegmatites in drilling on the tenure.
Four of four holes drilled in the company’s most recent exploration program struck pegmatite mineralisation, over varying thicknesses between 1 metre and 60 metres.
Lithium levels were at the lower end, the highest result being 940 parts per million or 0.2% lithium.
Evaluating next steps
“Drilling at Mt Palmer, at our Vickers Find Lithium Targets, has been technically successful, with the drilling intersecting broad widths of flat-lying pegmatites, with low-level lithium anomalism,” Aurumin managing director Brad Valiukas said.
“We will be evaluating the next steps at Mt Palmer.”
While AUN was able to confirm the pegmatites hosted LCT-style mineralisation, levels of lithium, in particular, were quite limited in nature, indicating they may not hold economical levels of lithium mineralisation for exploitation.
Further work will be needed to determine whether the project still retains lithium prospectivity.
