ReElement Technologies Eyes $150mn Boost for US Rare Earth Refinery

ReElement Technologies

Expanding US Rare Earth Refining Capacity

ReElement Technologies has secured a letter of interest from the US Export-Import Bank for up to $150mn in funding to expand its rare earth element (REE) and critical mineral refinery in Indiana. The investment would support the Marion Advanced Technology Center, enhancing its ability to produce 99.5% purity rare earth oxides and compounds, including neodymium, dysprosium, terbium, samarium, yttrium, and gadolinium. This expansion aims to strengthen the United States’ domestic capacity to refine critical materials essential for clean energy, defense, and advanced manufacturing sectors.

The Marion facility, acquired in 2023, spans 50,000m² and is being transformed into a commercial-scale refining hub capable of producing not only rare earth oxides but also lithium carbonate, lithium hydroxide, and transition metals. This scale positions ReElement as a potential leader in US-based REE processing.

Competing with Chinese Production Costs

ReElement also operates a 700m² Commercial Validation Facility in Noblesville, Indiana, which produces REEs and battery-critical elements. The company claims to be one of the few — possibly the only — US commercial entity capable of producing these high-purity materials at costs competitive with, or lower than, Chinese production. This capability could significantly reduce the nation’s dependency on Chinese supply chains, a key strategic priority amid rising geopolitical tensions and growing demand for REEs in electric vehicles, wind turbines, and military technologies.

Industry analysts note that achieving cost parity with Chinese producers has historically been a major barrier for US refiners. If ReElement can scale production while maintaining cost efficiency, it could reshape the competitive landscape in the global REE market.

Strategic Implications for US Supply Chain Security

The potential $150mn financing aligns with Washington’s push to localize critical mineral supply chains. Rare earth elements are essential for energy transition technologies and high-performance defense systems, yet the US currently relies heavily on imports for refined materials. By expanding domestic refining capacity, ReElement could play a pivotal role in mitigating supply risks, fostering industrial resilience, and supporting US manufacturing competitiveness.

Furthermore, the partnership with the US Export-Import Bank underscores growing federal willingness to financially back strategic resource projects. This model of public-private collaboration may serve as a blueprint for accelerating critical mineral infrastructure nationwide.

The Metalnomist Commentary

ReElement’s potential funding deal is a milestone in US rare earth refining ambitions. By scaling production to commercial levels while competing with China on cost, the company could become a cornerstone of America’s critical mineral strategy. The challenge will be ensuring that operational efficiency and market demand grow in lockstep with expanded capacity.
