ReElement Technologies Corporation announced a strategic collaboration with Mitsubishi Materials Corporation that includes a strategic investment from the Japanese materials company. The partnership aims to develop critical mineral supply chains across the United States and Japan.

ReElement Technologies is a minority holding of American Resources Corporation (NASDAQ: AREC). The collaboration will focus on combining advanced feedstock sourcing, preprocessing, and refining capabilities between the two companies.

In the United States, the partnership will support ReElement's refining operations through feedstock sourcing, tolling, and offtake opportunities. In Japan, the companies will evaluate opportunities to commercialize rare earth and critical mineral recycling solutions using Mitsubishi Materials' recycling infrastructure and ReElement's chromatographic refining platform.

ReElement uses patented chromatography-based separation and purification technology to process various feedstocks including recycled materials, mine waste, and primary ores into high-purity critical mineral products. The company describes its platform as modular, scalable, and designed to reduce capital intensity and operating costs compared to conventional solvent-based refining methods.

"We are honored to partner with Mitsubishi Materials Corporation, a global leader in materials innovation and resource circulation," said Mark Jensen, Chief Executive Officer of ReElement Technologies.

Tetsuya Tanaka, Executive Officer and President of Mitsubishi Materials Corporation, stated the investment represents an initiative to advance the company's circular resource business expansion in both the United States and Japan, as outlined in their medium-term management strategy.

The collaboration comes as companies seek to address supply chain bottlenecks in critical mineral processing and reduce dependence on traditional refining methods concentrated in specific geographic regions.
