American Resources along with its portfolio company, ReElement Technologies Corporation, have entered into a antimony stibnite tolling agreement for the production of ultra-pure antimony, sulfide or antimony oxide from shipments of stibnite ore shipped to ReElement’s central Indiana facilities.

The purified antimony will be used to supply the domestic defense and commercial industries based on the two-year contract that automatically extends. Initial tolling fees and revenues from these initial volumes are forecasted to exceed $29 million annually, with significant expansion potential based on domestic demand.

ReElement has recently completed a successful pilot refining program of the antimony stibnite ore feedstock at its Noblesville, Indiana facility with positive yield and purity of at least 99.7 percent pure antimony sulfide. In addition to its current processing capacity at its Noblesville facility, ReElement is currently scaling up its refining capacity at its Marion, Indiana supersite where it will deploy a separate product circuit for high-purity antimony, alongside it’s rare earth oxides and battery minerals (lithium, cobalt, nickel) refinement and purification lines.

“ReElement is a midstream refiner and purifier of separate elements, showcasing the versatility, flexibility and scalability of our world-class refining capabilities. We have established ourselves as one of the only commercially viable refiners of dysprosium oxide (a heavy rare earth) in the United States, and now we have proven our leadership as one of the very few, if not the only, producers of Antimony sulfide. This critical material is essential for munitions manufacturing and other specialized applications in both defense and commercial markets,” said Mark Jensen, CEO of American Resources Corporation and ReElement Technologies.

“Various private and public sector stakeholders approached us to evaluate whether our propriety and patented refinement process at ReElement could successfully and efficiently process and purify antimony. Over the past few weeks, we have proven that not only can we produce high-purity antimony for industry and government use, but we can do so economically within the United States,” added Jensen.

“At ReElement, our team has dedicated more than three years developing specialized flowsheets for refining high-valued elements while also cultivating strong partnerships with feedstock providers to ensure a reliable and responsive supply chain. Recently ReElement has begun receiving and testing samples for germanium, yttrium, and other defense-critical elements that are increasingly being restricted or banned by China. We are confident in our ability to bring this capability back at scale to the United States,” concluded Jensen.

The antimony ore partnership is initially commencing at approximately 500 metric tons per month of stibnite ore for processing and refinement at ReElement, with the ability to significantly expand such volumes based on market demand.

American Resources Corporation is a leader in the critical mineral supply chain, developing innovative solutions both upstream and downstream of the refining process. The company and its affiliates focus on the extraction and processing of metallurgical carbon and iron ore, essential ingredients in steelmaking, as well as critical and rare earth minerals for the electrification market and recycled metals. Leveraging its affiliation and former parent status of ReElement Technologies Corporation, a leading provider of high-performance refining capacity for rare earth and critical battery elements, American Resources is investing in and developing efficient upstream and downstream critical mineral operations. These operations include mining interests in conventional and unconventional sources, recycling, and manufacturing.

ReElement Technologies, a wholly owned subsidiary of American Resources Corporation, is a leading provider of high-performance refining capacity for rare earth and critical battery elements. Its multi-mineral, multi-feedstock platform technology focuses on the refining of recycled material from rare earth permanent magnets and lithium-ion batteries, concentrated ores and brines, as well as coal-based waste streams and byproducts to create a cost effective and environmentally-safe, circular supply chain. ReElement has developed its innovative and scalable “Powered by ReElement” process which collaboratively utilizes its exclusively licensed intellectual property within its partners’ material processing flow sheets to more efficiently support the global supply chain’s growing demand for magnet and battery-grade products.
