American Terbium is applying its leachable HREE model to overlooked U.S. mine waste enriched in Dy–Tb–Y - a district-scale opportunity of ~70 million tons of legacy tailings and waste rock.
Heavy rare earths from legacy mine waste.
Already-mined
Feedstock
No blast. No strip. No new ground disturbance. The material is on the surface and ready to process.
8 Provisional Patents
An integrated technology platform for rare-earth recovery from the next generation of domestic feedstocks
A New Geological Model
Six years proving a new rare earth deposit type that is both easily leachable and more enriched in critical heavy rare earths - validated to NI 43-101 standards
Five Structural Advantages
1
Already-mined feed
No blasting, stripping, or new ground disturbance. Material is on the surface
2
Directly leachable
~24-hour residence time. >95% recovery. No comminution required
3
Regulatory advantage
Classified as reclamation, not mining. Environmental remediation with an economic output
4
Defence-critical basket
84× more Dy+Tb and 177× more Y as a share of total rare earths vs. the only operating North American mine
5
Capital-light
~$62M internal CAPEX vs. ~$595M industry average
