REalloys Inc. secured a $1.7 million Defense Logistics Agency contract to restart U.S. output of samarium and gadolinium, featuring a modular, semi-continuous processing system designed to sidestep large solvent extraction plants. The award funded engineering for a 300-ton-per-year facility built around modular reactors and a low-temperature, zero-waste metallurgical reduction process.
The approach emphasizes smaller, rapidly deployable modules able to be scaled and distributed, with direct recycling of byproducts and claims of lower capital needs and up to 50% reduced production costs. The contract followed REalloys’ March 2025 acquisition of Terves LLC assets via its PMT Critical Metals subsidiary and was framed as part of U.S. efforts to rebuild a domestic mine-to-magnets supply chain.
For defense and energy sectors this matters because samarium-cobalt magnets and gadolinium are essential in high-heat motors, stealth systems and reactor control rods; domestic, modular production reduces geopolitical supply risk and shortens lead times. The deal signaled a tangible shift from planning to onshore execution in critical-minerals manufacturing.

Trend Themes
-
Modular Small-scale Processing — Smaller, rapidly deployable processing modules enable localized production footprints that undercut the scale and capital intensity of traditional solvent-extraction plants.
-
Zero-waste Metallurgical Reduction — A low-temperature, zero-waste reduction method presents pathways for tighter material recovery, reduced environmental liabilities, and lower lifecycle costs for rare-earth refining.
-
Distributed Critical-mineral Supply Chains — Scaling production across multiple regional modules reduces single-point geopolitical risk and shortens lead times for strategic magnet and reactor-material supply.
Industry Implications
-
Defense Manufacturing — Onshore modular production of samarium and gadolinium strengthens secure, near-term sourcing for high-heat motors and stealth systems with reduced reliance on foreign suppliers.
-
Renewable Energy Components — Domestic, cost-reducing rare-earth processing could alter turbine and electric-vehicle supply economics by improving access to high-performance magnetic materials.
-
Specialty Magnet Production — Localized feedstock availability from modular plants supports more responsive magnet manufacturing and potential redesigns of motors that leverage higher-temperature samarium-cobalt alloys.
