Australian Rare Earths Limited (ASX:AR3) engages in the exploration and development of rare earth elements and uranium mineral resources in Australia. The company focuses on its flagship 100%-owned Koppamurra Rare Earths Project, comprising approximately 6,270 square kilometers of ionic clay-hosted deposits in southeastern South Australia and western Victoria that contain significant concentrations of light rare earth elements including praseodymium and neodymium, as well as heavy rare earth elements such as terbium and dysprosium; these elements are essential for high-strength permanent magnets used in electric vehicles, wind turbines, and other clean energy technologies. It also holds Queensland uranium assets to support the clean energy transition. Founded in 2019 and headquartered at Level 10, 111 Gawler Place, Adelaide, South Australia, the company was formerly known as Tawel Exploration Pty Ltd before changing its name in March 2021. In recent developments, Australian Rare Earths finalized a A$5 million grant agreement under the Australian government's International Partnerships in Critical Minerals program in early 2025, matching the funds to advance metallurgical testwork, a pre-feasibility study, demonstration facility, and regulatory approvals for the Koppamurra Project; it received a $1 million instalment in August 2025, bringing total government support to $1.75 million with further tranches expected in 2026.
