Solcoa exists to stabilize the western rare-earth metal supply chain—powering every fighter jet, EV, wind turbine, phone, and generator. We're among the very few companies outside China producing rare-earth metals—and the only one delivering a 100% U.S. supply of both light and heavy rare earths. Our carbon-zero process converts end-of-life magnets directly into metal, ready to accelerate energy independence and secure one of the world's most vital resources.
We are a lean, well-funded team rapidly accelerating Western rare-earth production. We're building a world-class team to solve this crisis.
