ReElement Technologies has formed a strategic collaboration with Mitsubishi Materials Corporation (MMC), a global leader in advanced materials and resource circulation, which includes a strategic investment in ReElement.

The strategic investment underscores MMC’s confidence in ReElement’s refining-first platform and further aligns both companies in advancing scalable, economically viable solutions for critical mineral supply chains across the United States and allied nations.

“We are honored to partner with Mitsubishi Materials Corporation, a global leader in materials innovation and resource circulation. Their commitment and long-term vision reinforce the importance of building secure and resilient critical mineral supply chains across the United States and allied nations,” said Mark Jensen, chief executive officer of ReElement Technologies.

“By combining MMC’s expertise in feedstock sourcing and recycling with ReElement’s refining-first platform, we are advancing a scalable and economically viable solution to the midstream bottleneck — one that supports both national security and long-term industrial competitiveness,” added Jensen.

“This Investment represents an important initiative to concretely advance the enhancement and global expansion of our circular resource business, as outlined in our medium-term management strategy, in both the United States and Japan. By leveraging ReElement’s proprietary separation and refining technology, we will work to build a circular resource supply chain in North America, while also conducting a feasibility study toward joint business development in Japan, thereby accelerating the realization of these initiatives,” said Tetsuya Tanaka, executive officer and president, Mitsubishi Materials Corporation.

Through this collaboration, ReElement and MMC aim to develop integrated, scalable solutions that enhance supply chain resilience while supporting domestic and allied manufacturing capabilities.

LEVERAGING COMPLEMENTARY STRENGTHS

In the United States, the collaboration will focus on supporting ReElement’s refining operations through feedstock sourcing, tolling, and offtake opportunities, enabling the continued expansion of domestic refining capacity.

In Japan, the parties will jointly evaluate opportunities to commercialize rare earth and critical mineral recycling solutions, leveraging MMC’s established recycling infrastructure and ReElement’s proprietary chromatographic refining platform.

A REFINING-FIRST APPROACH TO SUPPLY CHAIN SECURITY

ReElement’s patented chromatography-based separation and purification technology enables the efficient processing of a wide range of feedstocks — including recycled materials, mine waste, and primary ores — into high-purity critical mineral products.

Unlike conventional solvent-based refining methods, ReElement’s platform is designed to be modular, scalable, and environmentally responsible, with reduced capital intensity, lower operating costs, and minimized environmental impact.

This refining-first approach addresses one of the most significant bottlenecks in the global critical mineral supply chain - the ability to economically separate and purify materials at scale.

A NEW MODEL FOR DOMESTIC AND ALLIED REFINING

ReElement’s refining-first platform is designed to compete globally while enabling domestic and allied supply chains. Its ability to process both recycled and primary materials into high-purity outputs positions the company as a scalable solution to the midstream refining gap.

Unlike traditional solvent-based refining methods — often difficult to deploy outside of China due to environmental, capital, and operational constraints and risks — ReElement’s approach offers a more efficient, modular, and environmentally responsible alternative.

ReElement Technologies, a minority holding of American Resources Corporation, is a leading provider of high-performance refining capacity for rare earth elements and critical minerals. Its refining-first, multi-mineral, multi-feedstock platform is designed to process a wide range of inputs — including recycled materials from permanent magnets, lithium-ion batteries, and industrial, defense, and technology waste streams, as well as mined ores, brines, and coal-based byproducts — into high-purity products that support a cost-effective, environmentally responsible, and circular supply chain. ReElement’s innovative and scalable process leverages its exclusively licensed and internally developed intellectual property, integrating directly into partners’ material processing flowsheets to enhance efficiency and adaptability across the global critical mineral supply chain.

Mitsubishi Materials Corporation is a leading Japanese materials manufacturer with a diverse portfolio spanning metals, advanced materials, and resource recycling. The company operates globally across copper smelting and refining, electronic materials, and recycling businesses, and is focused on advancing a circular economy through the efficient use and reuse of resources. Through its recycling and resource circulation initiatives, Mitsubishi Materials is committed to supporting the stable supply of critical materials essential to electrification, advanced technologies, and sustainable infrastructure.
