The Yinnetharra Li/REE project consists of two tenement applications, E09/2628 and E09/2641 (Figure 1 and 2), within the Gascoyne lithium region, located about 100km northeast of Gascoyne Junction and 85km south of Hastings Rare Earths (ASX:HAS) world-class Yangibana rare earths project.
The project area is underlain by Durlacher Supersuite of the Mangaroon Orogeny consisting of multiple granitic intrusives, mainly the schistose Davey Well Granite, gneissic granites and schists. Multiple potentially REE bearing pegmatites of the Thirty Three Supersuite have been mapped within the area.

Exploration history and potential
Numerous lithium bearing pegmatites have been identified in the nearby Thirty Three Supersuite, a large northwest-southeast granite unit along the Ti Tree shear zone, known to host REE-bearing pegmatites in the basement. Arrow Minerals (ASX:AMD) uncovered rockchip results of up to 3.77% Li2O at their Reid Well prospect at the Malinda Lithium project, 10km to the northwest of Yinnetharra.
Rock chip samples collected by GSWA within E09/2628 reported strong responses in Cerium up to 332ppm as viewed on GeoviewTM.
