Reserve Valuation
Heavy rare earths are the most valuable elements per unit mass. At a blended estimated value, the 15,000 tonnes of probable HREE reserves at the Guayana Highlands deposit represent an estimated in-ground value of $3–5 billion USD. Dysprosium alone can reach $350/kg, and terbium exceeds $1,400/kg — reflecting the extreme supply concentration with 95%+ of global HREE production in a single jurisdiction.
Available Elements
| Element | Symbol | Z | Primary Application | Approx. Price |
|---|---|---|---|---|
| Dysprosium | Dy | 66 | High-temp NdFeB magnets (EV, wind, military) | ~$350/kg |
| Terbium | Tb | 65 | Green phosphors, NdFeB magnets, magnetostriction (sonar) | ~$1,400/kg |
| Europium | Eu | 63 | Red and blue phosphors for displays, security banknotes | ~$30/kg |
| Yttrium | Y | 39 | Yttria-stabilized zirconia (YSZ), YAG lasers, superconductors | ~$35/kg |
🧲
Dysprosium — The Stabilizer
5% Dy in NdFeB magnets raises maximum operating temperature from 150°C to 220°C. Without Dy, EV motors demagnetize.
📺
Terbium & Europium — Color
Responsible for green (Tb) and red (Eu) colors in LED screens, fluorescent tubes, and banknote security features.
⚡
Yttrium — Future Ceramics
YSZ ceramics are the foundation of thermal barriers in turbines, fuel cell electrolytes, and medical prosthetics.
🔬
Quantum Applications
Yttrium and dysprosium isotopes are being researched for quantum computing qubits and precision atomic clocks.
