Tambourah Metals uncovers elevated lithium values at its Shaw River project

Estimated read time 3 min read

Rock chip sampling at Shaw River returns strong lithium, tin and tantalum assays
Tambourah Metals says most elevated lithium values are associated with biotite-bearing pegmatites
Further exploration to be carried out at anomalous rock chip sites

 

Special Report: Exploration at Tambourah Metals’ Shaw River project near Port Hedland, WA, is uncovering signs of its lithium potential with rock chip sampling returning up to 3,660ppm Li.

Shaw River was acquired from Minrex Resources (ASX:MRR) in July 2023 and contains the historical Shaw River tin field that was mined extensively for alluvial tin deposits.

It sits on the southern margin of the Cooglegong Monzogranite, a “tin granite”, and is part of the regionally important Split Rocks Supersuite associated with major pegmatite-hosted lithium deposits in the Pilbara.

Since acquiring the tenement, Tambourah Metals (ASX:TMB) has completed rock chip sampling, shallow auger sampling of alluvial dumps and localised RC drilling below historical alluvial workings as part of a reconnaissance program to assess the potential for pegmatite-hosted LCT mineralisation.

Exploration unlocking lithium potential

TMB collected 109 rock chip samples from two areas broadly corresponding with alluvial channels, firstly in the Old Shaw Creek area and secondly around the Shaw River near the north-western area of the tenement.

This returned up to 3,660ppm lithium, 4,251ppm tin and 129ppm tantalum with most of the elevated lithium values associated with biotite-bearing pegmatites.

Meanwhile, shallow auger sampling over tailings dumps related to the historical Shaw River mine has returned modest values of lithium, tin and tantalum.

Selected samples will be re-submitted for fusion analysis to check the acid digest results.

RC drilling around the area of the Old Shaw River Creek workings have also returned consistently elevated background LCT elements, which is indicative of a fertile, fractionated granite as a potential source for pegmatite-hosted LCT mineralisation.

 

Further activity

TMB will now evaluate anomalous rock chip sites and extend sampling over the project, noting geological controls.

It will also investigate fractionation trends within existing data to identify zoning within the Cooglegong Monzogranite.

Additionally, the company will re-assay selected auger samples from alluvial dumps using a fusion analytical method for tin and tantalum.
