Tawana Resources boss Mark Calderwood has hinted at accelerating exploration at the Bald Hill operation in the wake of a drilling and mapping program revealing multiple lithium and tantalum pegmatites.

Yesterday, the lithium developer announced its extensional step-out drilling and mapping at the joint venture, with Singapore-listed Alliance Mineral Assets Limited, had increased the known lithium and tantalum footprint.

Results included hits of 31m at 1.46 per cent Li2O from 143m and 35m at 1.74 per cent Li2O from 146m at Bald Hill, 50km south-east of Kambalda.

Mr Calderwood said the high-grade intersections could prompt Tawana and Alliance to ramp up exploration at the project in a bid to discover new lithium sources.

“With a number of significant resource targets, the joint venture is considering increasing the pace of drilling in the new year,” he said.

“One rig will continue with infill drilling whilst one to two rigs will work on step-out drilling and testing newly discovered lithium pegmatites.”

The latest exploration focused on initial grade control, water bore installation and water exploration drilling, with a single water hole intercepting three spodumene pegmatites about 700m west from the starter pit.

Tawana drilled 87 reverse-circulation holes, totalling 12,222m, and seven core holes, for 750m, between August 2 and October 4.

Only 20 of the holes were completed in time to be included in the company’s resource estimate, announced in October. Last month, SMS Innovative Mining agreed to a four-year $200 million deal with Tawana to offer equipment hire and mining services at Bald Hill.
