High Grade Mineralisation Extends South of Koppamurra

Highlights:

• New rare earth discovery south of Koppamurra: Assay results from a regional hand auger program have identified shallow clay-hosted rare earth mineralisation up to 60 km south of AR3’s Koppamurra Resource (which includes 186 million tonnes at 712 ppm Total Rare Earth Oxides (TREO)(ASX 19/09/2023)).

• Extensive mineralised zone: Assays confirm the extensive nature of the mineralised clay, opening up the southern tenements to follow up exploration and providing strong evidence of the rare earth province potential.

• Shallow, high-grade clays: Shallow clays with rare earth grades and assemblages comparable to the Koppamurra Resource have been identified within previously unexplored southern tenements EL6942 and EL6943.

• Significant dysprosium (Dy) content: The samples contain Dy, a critical heavy rare earth element, at levels of up to 4.0% of the TREO content.

• High-grade mineralisation intersected includes:

• Hole/Sample 715464, 1,889 ppm Total Rare Earth Oxide (TREO) sampled 0.7m below surface, with 27.6% combined Neodymium/Praseodymium (Nd/Pr) and 3.1% Dysprosium (Dy)

• Hole/Sample 715321, 1,654 ppm TREO sampled 1.4m below surface, with 24.7% combined Nd/Pr and 2.2% Dy

• Hole/Sample 715497 1,631 ppm TREO sampled 0.7m below surface, with 22.4% combined Nd/Pr and 3.2% Dy

• Hole/Sample 715405 1,496 ppm TREO sampled 1.4m below surface, with 22.2% combined Nd/Pr and 3.2% Dy

• Hole/Sample 715299 1,286 ppm TREO sampled 1.0m below surface, with 23.0% combined Nd/Pr and 3.0% Dy

• Hole/Sample 715108 1,147 ppm TREO sampled 2.0m below surface with 20.5% combined Nd/Pr and 4.0% Dy
