The miner owns part of the project through its 8.29% stake in Pan Asia Metals (PAM), a South-East Asian focused explorer of lithium and tungsten.
PAM completed five drill holes for a total 587.5m to test for lithium mineralised pegmatites below the historical open pit.
All holes intersected the main pegmatite zone over downhole widths of about 10-40m.
Assay results indicate that moderate to low grade lithium is present in much of the pegmatites, especially those with visible lepidolite.
A total of 307m of trenching for nine trenches were excavated at the project and lepidolite rich pegmatites were found to occur in the lower walls, extending to floors of the trenches.
Trenching at Reung Kiet South yielded 90 samples averaging 1.41% lithium oxide and 20 outcrop and float samples averaging 1.58% lithium oxide.
“The results confirm wide intersections of lepidolite hosting pegmatite below the shallow historical open pit, with trenching and outcrop sampling work currently demonstrating open-ended potential to extend the deposit along strike to the south west of the old pit,” said chief executive Michael McNelly.
“The work to date has resulted in an open-ended mineralised strike of approximately 1km being identified.
“We look forward to supporting PAM as it continues to push the project forward and will announce further updates in due course.”
