Koppamurra, South Australia

Koppamurra is a locality located within the Naracoorte Lucindale Council in the Limestone Coast region of South Australia. It abuts the eastern border of the state with Victoria.

The Koppamurra rare-earth mining project, owned by Australian Rare Earths, is based on a deposit containing four critical rare earth elements: praseodymium, neodymium, terbium, and dysprosium. As of May 2023, the project held multiple exploration licences including four in South Australia, and one in Victoria, covering over 4,000 km² (1,500 sq mi). In December 2024 the project received a AU$5 million government grant under its "International Partnerships in Critical Minerals" program, to support a demonstration plant.
