ReElement Technologies and POSCO International America Sign Long Term Commercial Offtake Partnership to Advance U.S. Rare Earth Refining Capabilities

Agreement advances U.S.-South Korea collaboration and supports sustainable supply chains for defense, clean energy, and advanced technologies

The parties have established a joint feedstock taskforce for sourcing domestic and international rare earth feedstock both recycled and from ore bodies

FISHERS, IN / ACCESS Newswire / September 29, 2025 / American Resources Corporation's (NASDAQ:AREC) portfolio company, ReElement Technologies ("ReElement"), a leading U.S. innovator in rare earth element (REE) and critical mineral refining, today announced it has signed a long-term offtake partnership with POSCO International America Corp ("POSCO"), a global leader in steel, magnetic materials, and advanced industrial solutions.

The partnership will combine ReElement's advanced chromatographic separation and purification platform with POSCO's extensive relationships throughout the automotive and industrial supply chain while leveraging POSCO's expertise in materials science and large-scale industrial deployment. This agreement reflects both companies' commitment to a sustainable and secure supply chain for high-purity rare earth elements critical to defense, clean energy, and high-growth markets such as electric vehicles, AI, and advanced semiconductors.

Highlights of the partnership include:

• Establishment of a joint taskforce to secure global feedstock streams, including mixed rare earth concentrate, magnet manufacturing waste and end-of-life scrap magnets

• Initial targeted offtake of purified separated rare earth oxides including Dy, Y, Tb and NdPr in volumes scaling to over 3,000 metric tons through 2030

• Co-development of rare earth refining capabilities in the United States

• Leveraging ReElement's modular and scalable refining technology to increase efficiency and reduce environmental impact

• Supporting secure, resilient, and sustainable supply chains for U.S. and allied nations

The signing of this agreement builds on the Memorandum of Understanding executed last week in Seoul, Korea, between ReElement and POSCO International, underscoring the companies' shared vision for long-term collaboration and industrial deployment.

"Our collaboration and growth over the last year with POSCO represents an important step forward for ReElement," said Mark Jensen, CEO of ReElement Technologies. "By combining our innovative and patented separation and purification technology with POSCO's unmatched industrial capabilities, we are not only scaling rare earth refining but also reshaping how these resources are supplied to global markets. This partnership strengthens the strategic bond between the United States of America and The Republic of Korea, while directly addressing one of the most pressing global challenges of our time: building resilient, transparent, and sustainable rare earth supply chains that support the national defense readiness and next-generation technologies. Together, we are proving that innovation and collaboration can deliver secure, long-term solutions for industries and nations that depend on these materials."
