Premier American Uranium Inc. (TSXV: PUR, OTCQB: PAUIF) has completed 50 drillholes totaling 41,960 feet at its Kaycee Project in Wyoming’s Powder River Basin, with results confirming uranium mineralization across the Rustler and Outpost target areas. The work represents about 42% of the company’s planned 100,000-foot 2026 exploration program, which began in early May.
The intercepts were measured from gamma-ray logs recorded by Hawkins CBM Logging of Casper, Wyoming, an independent contractor. Century Geophysics of Tulsa, Oklahoma handled the borehole geophysical logging. Grades were calculated at a cut-off of 0.02% eU₃O₈, using a procedure developed in the early 1960s that remains standard practice in the uranium industry.
Kaycee spans more than 42 square miles of mineral rights along a 36-mile trend hosting over 110 miles of identified roll fronts. The company says it is the only project in the Powder River Basin where all three historically productive sandstone formations – the Wasatch, Fort Union, and Lance – are mineralized and potentially accessible for in-situ recovery (ISR) extraction. Since 2023, the project has accumulated upwards of 400,000 feet of drilling, making it the largest grassroots ISR exploration project in the United States.
The triple-formation advantage matters for resource potential. Most PRB projects target only one or two of these units, which limits the footprint of mineralized rock per drillhole. At Kaycee, mineralized zones in each formation stack vertically; a single vertical hole can intersect multiple pay zones, lowering the cost per pound of discovery. The Lance Formation in particular is less explored than the Wasatch or Fort Union, meaning the current drilling could open up a new resource horizon, J.J. Brown, the company’s Vice President of Exploration, said in the release.
Premier American Uranium is running the Kaycee program alongside its Cyclone Project in the Great Divide Basin, giving it active exploration in both of Wyoming’s major ISR-amenable districts. The broader portfolio extends to New Mexico’s Grants Mineral Belt, with the company holding positions in five of the nation’s top uranium districts.
Strategic backers include Sachem Cove Partners, IsoEnergy Ltd., and Mega Uranium Ltd. The company’s land package sits in a district that has drawn attention as U.S. utilities seek domestic supply for reactor fuel. The broader uranium market has firmed this year on supply concerns from Kazakhstan and tightening conversion capacity, though spot prices remain well below the levels that drove the last exploration cycle.
Brown, a Qualified Person under National Instrument 43-101, reviewed and approved the technical information in the release. She verified the sampling, analytical, and test data. The mineralized zones are flat lying and the drill holes are vertical, so the reported thicknesses are considered true thicknesses.
Premier American Uranium plans to drill the remaining roughly 58,000 feet through the season, with further results expected as the program progresses. A technical report for the Kaycee Project, dated September 21, 2025, is available on SEDAR+.
