Highlights

• Australia's first open-access rare earth processing facility opens Q1 2026 at Lucas Heights.
• The facility addresses the critical refining bottleneck that has forced 100% of Australian concentrates to be processed overseas, primarily in China.
• The taxpayer-funded ANSTO facility enables clay-hosted rare earth processing from desorption to separated oxides.
• Australian Rare Earths' Koppamurra project will be the first user of the facility.
• Social license and regulatory risks remain a concern.
• This development marks a strategic policy shift recognizing refining as state-supported infrastructure rather than purely commercial activity.
• The move directly challenges China's 85% control of global processing capacity built on decades of subsidies.

Australia is poised to open its first open-access rare earth processing facility in early 2026—a move that quietly addresses the most consequential bottleneck in the global rare earth supply chain: refining. As first reported by Rare Earth Exchanges™, the facility is being constructed by the Australian Nuclear Science and Technology Organisation (opens in a new tab) (ANSTO) at Lucas Heights in Sydney. It is taxpayer-financed, purpose-built for clay-hosted rare earth deposits, and designed to operate as shared national infrastructure. In strategic terms, this matters more than another mine.

Australia is already the world’s fourth-largest rare earth producer

Yet until now it has exported 100% of its rare earth concentrates for overseas processing—largely to China. That contradiction has long undermined Australia’s ambition to be a serious player in critical minerals. The Lucas Heights facility represents a deliberate attempt to close that gap by enabling onshore refining, testing, and technical validation, rather than shipping value and know-how offshore.

Just as importantly, the plant makes explicit what is often left unsaid in Western policy debates: refining does not emerge without state support. China’s dominance in rare earth processing is not simply geological—it is structural, built on decades of state-subsidized refining, environmental tolerance, and guaranteed throughput. Australia’s move acknowledges that reality.

Rare Earth Exchanges has repeatedly argued that refining—unlike mining—often requires public co-investment to be viable in Western jurisdictions. Australia is now acting on that premise.

In an email to Rare Earth Exchanges Kellie McCourt, Media Affairs Manager for ANSTO went on the record:

“ANSTO has been supported by the Australian Critical Minerals R&D Hub, to extend its rare earth processing facilities to accommodate the emerging cohort of ionic clay and clay hosted rare earth projects.”

According to the ANSTO communication:

“The Australian Critical Minerals R&D Hub brings together expertise from Australia’s leading science agencies, ANSTO, CSIRO and Geoscience Australia to address technical challenges that support the Australian Government’s Critical Minerals Strategy.”

McCourt further elaborated on an aggressive timeline:

“A purpose-built pilot plant for clay processing will be designed, installed, and commissioned at ANSTO’s Lucas Heights campus in Sydney and will be ready in the first quarter of 2026. The facility will enable Australian companies to demonstrate all aspects of clay processing from desorption through to impurity removal and further rare earth processing and will complement ANSTO’s existing hydromet pilot plants and solvent extraction rare earth separation facility.”

The Koppamurra Test Case—and the Fault Line Beneath It

The first user of the ANSTO facility will be Australian Rare Earths (ASX: AR3) (opens in a new tab) and its proposed Koppamurra ionic clay rare earth project in South Australia. Koppamurra is notable: it would be Australia’s first large-scale ion-adsorption clay (IAC) rare earth proposal, targeting magnet-critical elements including dysprosium and terbium.

But it remains at an early stage. The project has an approved scoping study, no mining license, and, according to Australian media, faces active landholder resistance in the Wrattonbully region. Local farmers have raised concerns about agricultural land use, soil health, and long-term regional identity. These are not abstract ESG talking points—they are live political risks.

AR3 has been explicit that access to ANSTO’s pilot plant is essential to “de-risk” metallurgy and processing pathways. That dependence cuts both ways. The facility lowers technical risk, but it does not resolve social license, regulatory approval, or commercial certainty. Investors should watch closely as AR3 prepares to seek a mining license in 2026.

Inside the Plant: Why This Is More Than a Pilot

ANSTO’s facility is designed to process clay-hosted rare earths from desorption through impurity removal and into separated products, complementing its existing hydrometallurgical and solvent extraction capabilities. In practical terms, this means producing mixed rare earth precipitates and calcined oxides at pilot scale, not merely upgrading concentrate.

Critically, the plant is open-access. Any credible company can bring bulk clay samples and immediately begin testwork—without building a bespoke pilot facility or burning years of capital. This common-user model addresses a classic market failure: miners won’t invest in processing without certainty, and processors won’t build capacity without feedstock. The state steps in to break the deadlock.

This is why the announcement matters far beyond Koppamurra.

A Strategic Signal—Not Just an Australian One

China controls roughly 85% of global rare earth processing capacity, much of it state-supported. Australia’s move sends a clear signal: refining is infrastructure, not just industry.

Processed rare earth oxides can command four to five times the value of raw concentrates. By exporting unrefined material, Australia—and much of the West—has effectively outsourced both margin and leverage. The Lucas Heights plant is a step toward reversing that imbalance.

For investors, the message is nuanced but clear. The processing pathway is now credible. The policy intent is real. But commercial success is not guaranteed. No ionic clay rare earth mine has yet been commercialized in Australia. Offtake agreements are absent. The ANSTO facility will de-risk—but not replace—market discipline.

Bottom Line

This is not just a pilot plant. It is a policy admission: without state-supported refining, rare earth supply chains outside China will remain incomplete.

Australia has moved first. Others—including the United States—may soon face the same conclusion, even with existing loans to bolster refining capacity, such as the U.S. Department of War $150 million loan awarded to MP Materials (opens in a new tab) to add heavy rare earth (HREE) separation capabilities to their existing facility in Mountain Pass, California.
