The lithium prospects are located in the world-class Wodgina pegmatite and greenstone district which is 20-50km away from three existing lithium-tantalum projects currently in production or under development.

This district hosts historical Wodgina Tantalite (Ta) and Beryl (Be) pegmatite mines as well as the Mount Cassiterite (Sn-Ta) deposits. These three minerals are strong pathfinder elements for lithium-rich pegmatites. The Wodgina and Mount Cassiterite pegmatites have discrete units of Spodumene (main lithium mineral), Lepidolite (lithium mica) and Lithiophilite (lithium manganese phosphate).

The area under application consists of a north-east plunging synformal ultramafic system intruded by numerous granites and associated pegmatites. This is a similar geographical setting to the Wodgina and Pilgangoora deposits and other LCT (lithium-cesium-tantalum) pegmatite belts. The area is highly prospective for fractional pegmatite swarms that have resulted in zonal differentiation of lithium-tantalum rich zones. It also has historical sampling indicators of beryllium-rich pegmatites, which are know associated minerals for pegmatites. 

The region itself has been shown to host economic deposits of tantalum and lithium-rich spodumene. Due to this, and the lack of historical exploration for lithium in the area under application, it is seen as a priority greenfields exploration project. The areas under application consist of a very large tenement holding of approximately 878km2.
