American Terbium is applying its leachable heavy rare-earth model to overlooked U.S. mine waste enriched in dysprosium, terbium and yttrium, beginning with an estimated 70-million-ton district-scale inventory of legacy tailings and waste rock.
Heavy rare earths from legacy mine waste.
Already-Mined
Feedstock
American Terbium targets tailings and waste rock already at surface, reducing the need for blasting, stripping and new mine disturbance.
8 Provisional Patents
An integrated rare-earth recovery platform spanning mineral pre-treatment, chloride leaching, downstream separation and acid recovery.
A New Geological Model
A technical model developed over six years to identify leachable, heavy rare-earth-enriched feedstocks, with the original model supported by NI 43-101 technical-report work.
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
