TenSleep Project
Highlights
Project Details
The TenSleep Uranium Project represents a unique uranium opportunity in Wyoming, displaying geological characteristics similar to high-grade uranium deposits in Saskatchewan’s Athabasca Basin, rather than the more common roll-front deposits found in the U.S.
Uranium mineralization at TenSleep is associated with the contact between the TenSleep Formation and the overlying Phosphoria Formation, a geological setting known for hosting significant uranium deposits. Exploration drilling in the early 1970s demonstrated the presence of two uranium-bearing zones, yet the deeper unconformity target remains largely untested.
Nuclear Fuels acquired the 3,000-acre project through staking and state mineral leases. The company is currently reviewing historical data to refine an exploration program targeting the deeper unconformity-style uranium zone, with drilling planned for late 2025 or early 2026.
Historical Exploration
1950s: The Jeri-Marie underground mine operated on-site, confirming uranium presence.
1971-72: Aquarius Resources & Northwestern Energy drilled 111 holes, identifying two uranium zones.
1978-80: Cherokee Exploration recognized the potential for unconformity-style uranium but never followed up due to market conditions.
2025+: Nuclear Fuels plans to conduct modern exploration targeting higher-grade unconformity deposits and assess ISR viability.
Geology & Mineralization
Uranium mineralization is found along the contact between the TenSleep and Phosphoria Formations.
The TenSleep Formation is ~380 feet thick, consisting of fine- to medium-grained sandstone.
Historical drilling indicates uranium occurs at both the upper and lower contacts of the formation.
The lower contact represents an exciting new target for unconformity-style uranium mineralization, a model not previously explored at TenSleep.
Exploration Plan
Nuclear Fuels is developing a targeted drill program to:
- Delineate the extent of uranium mineralization at both the upper and lower contacts.
- Evaluate ISR amenability, which offers a low-impact, environmentally friendly extraction method.
- Leverage extensive historical data and modern geological modeling for efficient exploration.
