Arizona Tribune - ReElement Technologies Announces Strategic Collaboration with Mitsubishi Materials Corporation to Advance U.S. and Allied Critical Mineral Supply Chains

FISHERS, IN / ACCESS Newswire / March 31, 2026 / American Resources Corporation (NASDAQ:AREC) ("American Resources"), through its affiliated minority holding in ReElement Technologies Corporation ("ReElement"), a U.S. innovator in rare earth element (REE) and critical mineral refining for commercial and defense industries, today announced 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.

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.

Mark Jensen, Chief Executive Officer of ReElement Technologies, stated: "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."

"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."

Tetsuya Tanaka, Executive Officer and President, Mitsubishi Materials Corporation, commented: "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."

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.

Platform Advantages

ReElement's refining technology enables:

• Modular and scalable capacity expansion

• Localization of processing near feedstock or end markets

• Reduced chemical, energy, and labor intensity

• Multi-mineral, multi-feedstock flexibility across recycled and primary inputs
