American Rare Earths Boosts Wyoming Project Scale with $1.07B NPV Update — American Rare Earths Limited

Event summary

American Rare Earths' updated Scoping Study for Cowboy State Mine estimates after-tax NPV of $1.07B at 8% discount rate, up from $558M in 2025 base case.
Planned throughput increased 50% to 4.5M tonnes per annum with NdPr oxide production rising 36% to 2,500 tonnes annually.
Mine life extended to 26 years from 20 years, with initial capital estimated at $900M including 30% contingency.
Recovery optimization work ongoing with partners Nagrom and Saskatchewan Research Council targeting late Q2 2027 for separated rare earth oxide.
Company advancing permitting, infrastructure studies, and metallization test work with Novex for oxide-to-metal conversion.

The big picture

The updated study positions Cowboy State Mine as a potential cornerstone of U.S. rare earth supply chain independence, competing with Chinese dominance. The 50% scale increase and extended mine life reflect growing strategic importance of domestic critical mineral production. Success will depend on overcoming technical hurdles in recovery and securing substantial project financing.
