Mulberry and Ramaco Pursue Domestic Rare‑Earth Supply MOU

Mulberry Industries and Ramaco Resources announced a non-binding memorandum of understanding to negotiate an offtake partnership aimed at strengthening a U.S. rare-earth and permanent magnet supply chain.

Under the MOU, Ramaco would supply customized oxide blends containing samarium, neodymium-praseodymium (NdPr), yttrium, gallium and dysprosium/terbium (Dy/Tb) on a non-exclusive basis. Mulberry plans to use the domestic feedstock to bolster a 10-year rare-earth stockpile and manufacture advanced permanent magnets at its Georgia facility for defense, aerospace, automotive and robotics customers.

Mulberry produces NdFeB, SmCo and AlNiCo magnets and is one of the few Western end-to-end producers of samarium-cobalt magnets used in critical defense systems. The company says its integrated production flow is roughly 60% more streamlined than peers and that its fifth-generation Grain Boundary Diffusion (GBD) process reduces heavy rare-earth usage by 30–80%, yielding lighter, higher-performance magnets.

Ramaco’s Brook Mine in Wyoming, described as the first new U.S. rare-earth and critical-mineral mine in decades, has commenced mining and is constructing a pilot processing plant to supply commercial oxides.

Both firms framed the potential deal as a step toward an ex-China supply chain to improve industrial resilience and national security.
