TSX-V-listed Ucore Rare Metals has successfully produced commercial-grade neodymium-praseodymium (NdPr) oxide and shipped initial qualification samples to major rare earth permanent magnet manufacturers for technical evaluation.

The sample shipments mark an important step in Ucore's strategy to connect its RapidSX rare earths separation platform directly with downstream magnet, metal, alloy and advanced materials supply chains.

NdPr oxide is a critical midstream material that is converted into metal and alloy feedstock for neodymium-iron-boron (NdFeB) permanent magnets, which are used across high-performance motors, robotics, electric vehicles, industrial automation, renewable-energy systems, and defence applications.

The NdPr oxide qualification samples were produced as part of Ucore's ongoing demonstration and commercialisation work.

During this work, the company's 52-stage RapidSX demonstration plant in Kingston, Ontario, processed a heavy mixed rare earth oxide (MREO) feedstock derived from an ionic clay source and produced 99.5%+ NdPr chloride.

Ucore subsequently converted a portion of this chloride solution into 99.5%+ NdPr oxide.

Ucore previously announced strategic relationships with major rare earth permanent magnet manufacturers that are working to expand Western magnet production capacity. These relationships are intended to position Ucore as a midstream rare earth oxide supplier for strategically important downstream manufacturers focused on rebuilding North American and allied rare earth magnet supply chains.

In addition to using dysprosium and terbium, which Ucore plans to produce in Louisiana, these magnet manufacturers also use NdPr oxide, which is expected to be an important part of Ucore's product suite at its prospective Louisiana Strategic Metals Complex (SMC). 

"Sample qualification is a critical step toward developing potential offtake arrangements. The NdPr oxide shipped to major rare earth magnet manufacturers was not produced in a concept study. It was produced through Ucore's RapidSX demonstration platform, from real mixed rare earth feedstock, and is now in the hands of companies working to develop Western magnet manufacturing capacity," says Ucore chairperson and CEO Pat Ryan.

Ucore COO and VP Mike Schrider adds that oxide quality matters for downstream customers.

"Purity, impurity control, physical form, consistency, conversion performance, and traceability all have to be understood before commercial supply can begin. These samples give potential customers the material they need to evaluate Ucore's rare earth oxides against their own technical and manufacturing requirements," he states.

This work also gives Ucore direct feedback from downstream customers as it continues to translate the learnings from its Kingston demonstration facility into the design, construction, commissioning, and operational plans of the Louisiana SMC.

CUSTOMER QUALIFICATION

The evaluation work by major downstream customers focuses on confirming that Ucore's rare earth oxides meet the technical, quality, and traceability requirements for use in Western magnet and advanced materials supply chains.

The qualification process is expected to include independent chemical assay work to confirm rare earth oxide purity and key impurity levels; confirmation of oxide characteristics, including phase composition, handling, moisture, and consistency; assessment of compatibility with magnet manufacturing requirements, including alloy formulation, process qualification, and finished magnet compliance expectations; and development of product specifications, quality assurance protocols, logistics requirements, and commercial terms to support definitive long-term supply agreements.

This qualification process is a key step toward elevating strategic relationships currently at the memorandum-of-understanding level and could contribute toward potential commercial offtake arrangements.

It allows downstream manufacturers and advanced materials customers to certify that Ucore's separated rare earth oxide products meet their required technical specifications before larger-volume supply commitments are finalised.
