Ucore announces: 
- Ucore has produced 99.5%+ neodymium-praseodymium oxide generated at its 52-stage RapidSX™ Demonstration Plant in Kingston, Ontario
- Initial NdPr oxide qualification samples were shipped to major rare earth permanent magnet manufacturers serving North American and European supply chains
- Testing of the samples begin the process of confirming purity, phase composition, consistency, and compatibility with customer-compliant NdFeB permanent magnet manufacturing processes
- The qualification work is intended to support the development of structured definitive supply agreements aligned with Ucore’s planned Louisiana Strategic Metals Complex and its Commercialization and Demonstration Facility in Kingston, Ontario
Halifax, Nova Scotia–(Newsfile Corp. – June 22, 2026) – Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX: UURAF) (“Ucore” or the “Company“) is pleased to announce that it has 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 earth 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 defense applications.
The NdPr oxide qualification samples were produced as part of Ucore’s ongoing demonstration and commercialization work. During this work, the Company’s 52-stage RapidSX™ Demonstration Plant at its Commercialization and Demonstration Facility (“CDF“) 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.
Strategic Alignment with Western Supply Chain Development
Ucore has 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 utilizing dysprosium (“Dy”) and terbium (“Tb”), which Ucore plans to produce in Louisiana, these magnet manufacturers also utilize NdPr oxide, which is expected to be an important part of Ucore’s product suite at its prospective Louisiana SMC.
“Sample qualification is a critical step toward developing potential offtake arrangements,” stated Pat Ryan, P.Eng., Ucore’s Chairman and Chief Executive Officer. “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.”
Mike Schrider, P.E., Ucore’s Vice President and Chief Operating Officer, commented: “For downstream customers, oxide quality matters. 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.”
Schrider added: “This work also gives Ucore direct feedback from downstream customers as we continue to translate the learnings from our Kingston CDF into the design, construction, commissioning, and operational plans of the Louisiana Strategic Metals Complex.”
Customer Qualification: Turning Separated Oxides into Supply Chain Inputs
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 MOU 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 finalized.

Forward-Looking Statements
This press release contains “forward-looking information” and “forward-looking statements” (collectively “forward-looking statements” within the meaning of applicable Canadian securities laws. All statements in this release (other than statements of historical facts) that address future business development, technological development and/or acquisition activities (including any related required financings), timelines, events, products to be produced at the Louisiana SMC, or developments that the Company is pursuing are forward-looking statements. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance or results, and actual results or developments may differ materially from those in forward-looking statements.
For additional risks and uncertainties regarding the Company, its business activities, its ability to qualify for and receive any additional funding from any U.S. or Canadian government, the CDF and the aforementioned projects (generally), see the risk disclosure in the Company’s MD&A for Q1-2026 (filed on SEDAR+ on May 29, 2026) (www.sedarplus.ca) as well as the risks described below.
