Exploring the Heart of Wyoming’s ISR Uranium Belts
Projects Overview:
Noble Plains Uranium is advancing a high-impact portfolio across two of Wyoming’s most productive uranium basins — the Powder River and Shirley Basins — with a total of 117 mining claims and 4 State mineral leases.
Duck Creek Project (Powder River Basin): Advanced brownfield ISR target—2,560 acres (option to earn 80%) across 4 state mineral leases with 4,000+ historic drill holes defining a ~3-mile trend; shallow roll-fronts at ~50–400 ft with untested Fort Union potential at ~500–1,200 ft.
Shirley East and Shirley Central (Shirley Basin): 2,405 acres total — Shirley East 1,740 acres / 87 claims; Shirley Central 665 acres / 30 claims — in a proven ISR district adjacent to Ur-Energy/UEC with infrastructure and historical data.
With strategic land positions, ISR amenability, and historical data in place, Noble Plains is positioned in a jurisdiction with streamlined permitting to quickly advance exploration and unlock value as the uranium cycle accelerates.

Geology & Mineralization
The Duck Creek Project is underlain by the Eocene-aged Wasatch Formation, a well-known host for uranium mineralization in the Powder River Basin. Mineralization at Duck Creek is characterized by classic roll-front uranium deposits, which are shallow and amenable to in-situ recovery (ISR) methods. Over 4,000 historic drill holes have outlined a continuous, 3-mile-long corridor of uranium mineralization occurring from less than 50 feet to 260 feet below surface. The property also shows evidence of historic open-pit production from these near-surface zones. In addition to well-defined shallow resources, there is significant exploration upside potential in the deeper and untested Fort Union formation which holds significant mineralization in the district. This offers both near-term development potential and long-term growth opportunities.
Highlights
Over 4,000 historic drill holes from legacy operator Kerr-McGee define a 3-mile uranium trend.
Surrounded by ISR projects owned by Cameco, Uranium Energy Corp. (UEC), and GTI Energy.
Shallow roll-front mineralization identified between 50 and 260 feet depth, amenable to ISR.
Confirmation drilling is planned for later this year to advance the Project toward an initial NI 43-101 compliant resource estimate.

Geology & Mineralization
The project is underlain by Eocene-aged arkosic sandstones, known to host classic roll-front uranium deposits. These permeable sandstone units are confined by impermeable shale above and below, creating the ideal environment for uranium-bearing oxidized fluids to precipitate along redox boundaries.
Mineralization occurs as uraninite and coffinite coatings on sand grains—fully amenable to In Situ Recovery (ISR) mining methods.
Highlights
Classic Wyoming-style roll-front system
Mineralization hosted at shallow depths
ISR-compatible hydrogeology and chemistry
Multiple stacked intercepts within single holes
