Lithex Resources (ASX: LTX) is targeting hard rock and alluvial sources of tin and tantalum mineralisation at the Shaw River Project, with an Airborne Hyperspectral Survey underway.
Shaw River has historically produced tin and tantalum concentrates from alluvial deposits, with further alluvial sources identified.
HyVista Corporation has been commissioned to conduct the survey across the entire 418 square kilometre Shaw River group of tenements.
The survey aims to identify pegmatite rocks, which are known in the area to host heavy rare earth, tin, tantalum and lithium mineralisation.
Lithex's Shaw River project, located 50 kilometres south west of Marble Bar in Western Australia, hosted Australia's first rare earth mine which was worked in 1913 and 1930.
The mine produced about 2 tonnes of gadolinite, with an analysis of this material returning 45.78% yttrium and 4.81% of other rare earth oxides.
Moolyella maiden resource
In other company news, Lithex last month defined a Maiden Inferred JORC Resource of 1.9 million tonnes for the company's Moolyella tailings project in Western Australia's Pilbara Goldfield.
Preliminary metallurgical test work indicates recoveries of up to 84.7% for tin and 66.3% for tantalum. Lithex plans to conduct resource definition drilling to verify the historically identified resources.
The company will also conduct exploration drilling on newly identified targets at Moolyella.
