St George Mining pushes Araxá rare earths toward mine-to-magnet supply chain with REalloys and Brazil processing partners

St George Mining’s next step in rare earths is less about owning ore and more about proving that output can be turned into magnet-ready materials—an increasingly decisive factor for investors as governments and manufacturers seek independent critical mineral supply chains outside China.

The company, listed in Australia, says it is accelerating expansion along the global rare earths supply chain by positioning its Brazilian Araxá project as a fully integrated mine-to-magnet platform. The plan centres on partnership-driven progress from metallurgical validation through to downstream integration, rather than relying solely on resource development.

REalloys partnership targets downstream conversion

A key element of the strategy is St George’s collaboration with REalloys, described as a specialist in magnet materials and rare earth processing. The work is aimed at advancing metallurgical testing, optimising processes, and integrating downstream steps—particularly converting rare earth oxalates into higher-value products.

The company frames this focus around the role of permanent magnets across major end markets, including electric vehicles (EVs), wind turbines, defence systems and advanced electronics. Rather than exporting raw concentrates, St George says it wants to capture more value further along the chain.

The commercial intent behind the effort builds on earlier agreements under which REalloys could secure up to 40% of future production from Araxá. That outcome would depend on successful processing validation and final commercial terms.

• This type of offtake structure, St George argues, can provide revenue visibility.

• It may also improve project bankability.

• And it can reduce market risk as testing moves toward specification-grade material.

The company also links the arrangement to confidence in Araxá’s ability to deliver consistent, high-quality output.

Araxá’s size and grade underpin “Western-aligned” ambitions

Araxá is presented as one of the most significant rare earth deposits in South America. St George cites an estimated resource of 40.6 million tonnes grading at 4.13% total rare earth oxides (TREO).

The company says that combination of scale and grade could make Araxá relevant for Western-aligned supply chains as the United States and Europe attempt to reduce dependence on China. It notes that China still dominates over 80% of global rare earth processing capacity, while describing Brazil’s established mining framework as an additional factor supporting long-term development and investment appeal.

Brazil ecosystem build-out: separation tech to commercial-grade materials

St George says it is not limiting ambition to export markets. Instead, it aims to develop a domestic processing ecosystem in Brazil through partnerships with SENAI (Brazilian National Service for Industrial Training) and EMBRAPII (Brazilian innovation agency).

The collaborations are intended to advance technologies for:

• rare earth separation

• Niobium processing

• production of commercial-grade materials

This dual focus—local processing capability alongside global supply—feeds into what St George describes as greater flexibility and resilience for the overall project pathway.

MagBras engagement supports magnet manufacturing capacity

Toward magnet manufacturing end points, St George says it is engaging with Brazil’s MagBras initiative—a national program designed to establish permanent magnet manufacturing capacity. The company characterises this as part of a clear dual-market strategy: supplying international partners via offtake agreements while also supporting domestic industrial development.

It adds that initial shipments of processed rare earth samples have already been delivered to support magnet development and testing, marking early progress toward full value chain integration.

Tightening policy raises stakes for metallurgical validation

The timing matters because Governments in both the United States and Europe are intensifying efforts to secure independent critical mineral supply chains. St George highlights demand drivers spanning defence, clean energy and advanced manufacturing sectors.

The company also points to new policy measures restricting reliance on Chinese rare earth inputs—particularly for defence applications—as accelerating demand for alternative suppliers ahead of expected regulatory tightening between 2026 and 2027.

The next gate: flowsheets that meet high-performance specifications

For Araxá, execution now hinges on outcomes from metallurgical testing and finalisation of processing flowsheets. St George says these steps will determine whether the project can consistently produce materials meeting strict specifications required for high-performance magnets.

If achieved, management links the milestone directly to securing long-term financing, finalising commercial agreements and advancing toward full-scale production—steps that together would move Araxá from deposit potential toward validated industrial capability.
