The Koppamurra Project is a frontier ionic clay rare earth opportunity in South Australia and Victoria, Australia.


Australian Rare Earths (AR3) currently hold six Exploration Licences (ELs),  four covering the area between Comaum and Keith in South Australia and two cover the area between Apsley and Minimay in Western Victoria, Australia.

Two large prospects for rare earth elements have been discovered on AR3 tenements, being the Yellow Tail and Red Tail prospects. The maiden JORC 2021 Inferred Mineral Resource of 39.9Mt @ 725ppm TREO is detailed below.

AR3 is uniquely positioned to grow this maiden resource, with over 4,000km2 in exploration tenure in place in regionally analogous depositional settings to the red and yellow tail deposits.
