MinRex has identified large pegmatites hosting visible spodumene over the Tambourah North, Leavers Well and Twin Well project areas in WA’s East Pilbara region.

The areas were identified in the newly acquired projects following the company’s second ground reconnaissance field program, which also recovered 16 rock chip samples with assays pending.

MinRex Resources (ASX:MRR) adds that no modern exploration drilling for lithium has ever been carried out within the three project areas.

“We are delighted to have identified spodumene within extensive outcropping pegmatites over three project areas,” non-executive director and lithium geologist George Karageorge said.

“These rich spodumene stacked pegmatites have extensive width, strike and zoning which have all the hallmarks of a potential Archer Lithium Deposit.

“MinRex is currently working on the first RC drill program to test the extensive stacked pegmatites over all 3 project areas with a view of signing the drilling contractor to undertake drilling over the projects once all approvals have been issued.”

Lithium project areas

Tambourah North – located 200km south southeast of Port Hedland and 80km southwest of Marble Bar – hosts large, stacked pegmatites over 1.5km in length and 150m in width.

Notably, these pegmatites are housed in the same Soansville Group Formation that hosts Pilbara Minerals’ (ASX:PLS) 226Mt Pilgangoora lithium deposit and Mineral Resources’ (ASX:MRL) 236Mt Wodgina lithium deposit.

The pegmatites have visible coarse and fine grained Spodumene & Lepidolites with zoning along strike and across strike.

Goldilocks for swarming pegmatites

Over at Leavers Well, pegmatites hosting visible extensive coarse-grained tourmaline were observed along the low-lying areas through the upper ridges of the Hamersley Basin Sediments over a 1.5km by 450m area.

These pegmatites are located within the goldilocks zone where the geological settings are favourable for lithium mineralisation.

The Twin Wells prospect showed strong extensive stacked swarming pegmatites striking within a southerly direction over 650m.

It also hosts historical alluvial tantalum workings that are a strong indicator of localised lithium-caesium-tantalum pegmatites.

Forward exploration program

MinRex has applied for three work programs with the Department of Mines, Industry, Regulation and Safety for the purposes of drilling over the Coondina South (Leavers Well), Haystack Well (Twin Wells) and Tambourah North projects.

Advanced Heritage Agreement and Native Title Surveys are also progressing with the company expecting to start drilling in the second quarter.
