The company announced last month that five holes drilled into Earl Grey had returned outstanding results with high grades of up to 2.5 per cent Li2O over wide intervals.

“Significantly, all these holes were terminated in lithium mineralisation because they were targeted for gold. As a result, the actual thickness of the Earl Grey pegmatite is still unknown, although the exiting drill holes confirm a minimum of true width of approximately 50m,” the company said in a statement.

Kidman said it will now utilise a multi-purpose RC/Diamond drill rig to drill several RC pre collars followed by diamond tails to test the actual thickness of the mineralised pegmatite. According to the company, the program will then step to the south targeting the pegmatite up dip near surface and laterally along strike.


“The diamond core will be used in metallurgical testwork with the initial view of producing a saleable coarse spodumene concentrate and providing an opportunity to understand the mineralogy and grain size of the spodumene,” read the statement.

“Additional testwork will then assess recovery from the fines and gather information needed for process plant design.”
