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.

🛩️
Jet Turbines
SmCo magnets in jet engine sensors and actuators operate at 500°C+ without demagnetization.
🛰️
Satellites & Space
SmCo magnets are standard for reaction wheels, gyroscopes, and momentum motors in orbital systems.
⚛️
Nuclear Applications
Radiation resistance and thermal stability make SmCo the preferred magnet for reactor environments.
🎯
Guidance Systems
Missiles, torpedoes, and guided munitions use SmCo magnets for extreme reliability and miniaturization.
