MinRex has kicked off maiden drilling targeting pegmatites from surface and depths to determine the nature of battery metal mineralisation at the historical Shaw River tin-tantalum mine.

The reverse circulation drill program at the project also marks the start of an extensive 25,000m drilling campaign which will be carried out across its Pilbara lithium assets over the next 12 months.

No modern exploration for lithium has ever been conducted over the historical mine where only shallow auger drilling was used for alluvial grade control to depths of just 7m.

Field mapping carried out by MinRex Resources (ASX:MRR) in May 2022 outlined extensive pegmatites dykes in the northeastern portion of current tenure area proximal to the Old Shaw/Shaw River Tin and Crown Lands and Sundry Claims Tin mines.

The stacked pegmatites of between 40m and 210m in length striking in a northwestern direction are located within a zone of about 1,000m in length.

Most of the pegmatites are concealed by alluvial material and have never been subjected to modern hard rock exploration.

“We are delighted to have secured FORACO drilling services for the next 12 months of exploration drilling,” managing director George Karageorge said.

“The company is in a great position of securing Native Title Heritage Agreement with Nyamal Corporation over the Marble Bar tenements and Proposed Works approvals over all its projects from the WA Mines Department for continuation of drilling in the east Pilbara.”

Past tin producer

Shaw River is part of the Shaw River tin field that produced 6,585t of tin and 548t of tantalite concentrates – mostly from alluvial placer deposits – up until 1975.

Historical heavy stream sediment sampling has outlined very high-grade tin-tantalum mineralised zones with up to 42.2% tin and 3.41% tantalum within extensive pegmatite occurrences.
