Highlights

• ANSTO is constructing Australia's first taxpayer-financed, common-use rare earth processing facility for clay-hosted deposits, set to open in 2026 to reduce dependence on China for midstream processing.
• Australian Rare Earths' Koppamurra project will be the inaugural user of the facility, representing Australia's first large-scale ion-adsorption clay rare earth proposal despite lacking a mining license.
• While the processing facility marks a breakthrough in Australia's rare earth supply chain, significant landholder resistance and community concerns about agricultural land use threaten project viability.

Australia—already the world’s fourth-largest rare earth producer—has long lived with a strategic contradiction: prodigious resources but dependence on China for midstream processing. A new development reported by ABC (opens in a new tab) marks a serious attempt to close that gap. The Australian Nuclear Science and Technology Organisation (ANSTO) (opens in a new tab) is now constructing what is believed to be the country’s first common-use processing facility for clay-hosted rare earths, scheduled to come online in 2026. This would be a taxpayer-financed rare earth refinery.

Unlike mine-specific pilot plants, this state-owned facility will operate as open infrastructure. Emerging companies can walk in, bring their clay samples, and immediately begin hydrometallurgical testwork—no bespoke plant, no long delays, and no millions spent reinventing the same machinery. ANSTO is correct in emphasizing the importance of this integrated approach; without a midstream hub, Australia cannot meaningfully compete with China’s processing dominance.

The Koppamurra Test Case—and the Fault Line Beneath It

Australian Rare Earths (AR3 (opens in a new tab)) will be the facility’s inaugural user. Its Koppamurra project—the country’s first large-scale ion-adsorption clay (IAC) rare earth proposal—sits in South Australia’s Wrattonbully region. AR3’s scoping study was approved this month, and management is open about its dependence on ANSTO to “de-risk” the path toward commercialization.

The facts here are solid: Koppamurra is clay-hosted, not hard-rock; the company does not yet have a mining license; and farmers in the project footprint are voicing significant concerns about land use, soil health, and long-term agricultural identity. These tensions are real, not speculative. As is true across the global IAC landscape, the promise of lower-impact mining is often met with skepticism on the ground—particularly in fertile regions that pride themselves on generational stewardship.

Rare Earth Exchanges (REEx) was in touch with ANSTO’s media manager, Kellie McCourt, who confirmed the situation.  Ms. McCourt will be sending a separate statement that REEx will use for a follow-up article.  REEx also sent an email to AR3 for any comments.

AR3’s insistence on regulatory compliance is factual, but it skirts around the deeper community unease: many landowners view rare earth policy momentum in Canberra and state capitals as making approval inevitable, whether or not social license keeps pace.

What is ANSTO

ANSTO (Australian Nuclear Science and Technology Organisation) is Australia's national nuclear research organization, a public body using nuclear science for health, environment, and industry, operating major facilities like the OPAL reactor and Australian Synchrotron, producing nuclear medicines, advising the government, and providing national scientific expertise and infrastructure for researchers. 

Why This Matters for Rare Earth Investors

Australia’s clay deposits—if proven economically—could become a scalable non-Chinese supply for magnet-grade rare earths. But investors should carefully interpret this announcement. The facility is real; the processing pathway is credible; the geological potential is large. Yet Koppamurra is an early stage, landholder resistance is strong, and Australia has yet to deliver a commercial IAC project.

The pilot plant is a breakthrough. A mine is not yet a certainty.

What are some questions we have?

• Will they refine rare earth oxides?
• Will it be Australia's first, given it seems a taxpayer-financed effort?
• What companies/organizations are customers?
• What about offtake agreements in place?
