MinRex Resources Limited announced the RC drilling has commenced over the Shaw River Lithium-Tin-Tantalum Project. The Shaw River Project is part of the Shaw River Tin Field. The tin field is located within the Shaw Batholith, a complex structural dome comprising multiple granitoid intrusions.

Up until 1975, the Shaw River tin field produced 6,585t of tin and 548t of tantalite concentrates (containing 20.2t of Ta 2O5), with the greatest production from alluvial placer deposits. In May 2022, the first field mapping reconnaissance programme outlined extensive pegmatites dykes in the north-eastern portion of current tenure area proximal to the Old Shaw/Shaw River Tin and Crown Lands and Sundry Claims Tin mines. These pegmatites vary from 40m to 210m in length striking north-western direction.

These stacked pegmatites are striking within a zone approximately of 1,000m in length. Most of the pegmatites in the field are concealed by alluvial material with numerous pegmatites identified in the drainage and creeks cuttings. No hard rock exploration has been conducted over these pegmatites which have the potential to host lithium mineralisation.

No modern exploration for lithium was conducted over the historic tin - tantalum mine and only shallow auger drilling was used in the alluvial grade control drilling to only 7-meter maximum depths. During the year, MinRex Resource awarded the 25,000 drill metres to FORACO Drilling Australia based on the extensive experience drilling in Western Australia.
