Samarium (Sm)
30,000 tonnes of probable reserves at the Guayana REE Complex. Samarium produces the most temperature-resistant permanent magnets on the planet — essential for military, aerospace, and space applications.
SmCo magnets operate where neodymium fails: 300°C+, corrosive environments, and intense radiation. Processed SmCo magnets command $80-150/kg — dramatically increasing downstream value beyond the $120 million oxide valuation.
Reserve Valuation
At current oxide prices (~$4/kg for Sm₂O₃), the 30,000 tonnes of probable samarium reserves at the Guayana REE Complex represent an estimated in-ground value of $120 million USD. However, processed SmCo magnets command $80-150/kg, dramatically increasing downstream value.
Magnets That Survive Hell
Samarium-cobalt (SmCo) magnets operate in conditions where neodymium magnets fail: temperatures above 300°C, corrosive environments, and intense radiation. This makes them indispensable for jet turbines, satellites, nuclear reactors, and precision defense systems.
