Premier American Uranium Inc. has announced significant results from its extensive 2025 drilling campaign at the Kaycee ISR Uranium Project, located in the prolific Powder River Basin of northeastern Wyoming. The company, trading under the symbols TSXV: PUR and OTCQB: PAUIF, reported that the program successfully expanded known areas of uranium mineralization across multiple key exploration targets.
Major Drilling Campaign Delivers Positive Results
The 2025 exploration effort was substantial, comprising 132 drillholes for a total of 100,107 feet. This work focused on advancing several target areas within the project, which is situated near existing In-Situ Recovery (ISR) uranium operations, including those run by Energy Fuels Inc. and Uranium Energy Corp.
The drilling aimed to expand mineralization associated with major redox-controlled roll-front systems, a common geological feature for uranium deposits in the region. The results confirmed and extended mineralization in three primary areas: Outpost, Rustler, and Stampede.
Outpost Target Reveals New Roll Front System
Follow-up drilling in the Outpost target area confirmed the presence of a newly defined uranium-bearing roll front system within Fort Union Formation channel sands. This discovery builds upon positive results from late-2024 drilling.
Notably, eleven of the 23 holes drilled in this area encountered uranium mineralization. Eight of those holes intersected grades of 0.02% eU₃O₈ or greater with a minimum thickness of 2 feet. High-grade intercepts included 3.5 feet of 0.27% eU₃O₈ in drillhole LT25-065 and 5.5 feet of 0.125% eU₃O₈ in drillhole LT25-069.
Rustler Area Defines Continuous Corridor
Drilling in the Rustler area further defined a previously identified north-south trending redox-front, with mineralization hosted in Wasatch Formation channel sands. This corridor extends for approximately 3.5 miles, representing one of the most laterally continuous redox interfaces in the project area.
Out of 81 holes drilled in Rustler during 2025, 22 encountered uranium mineralization. Fifteen of those hits met the 0.02% eU₃O₈ grade over 2-foot thickness threshold. Significant intercepts included 8.5 feet of 0.083% eU₃O₈ in drillhole RT25-042 and 4 feet of 0.09% eU₃O₈ in drillhole RT25-064. The company notes that the host-sand and geologic characteristics appear favourable and similar to the nearby Nichols Ranch ISR project.
Stampede Area Connects the Trend
Mineralized intercepts in the Stampede area during the 2025 program demonstrate continuity of the Wasatch-hosted redox trend between Stampede and Rustler. This indicates that uranium mineralization extends along a broad north-south corridor, strengthening the regional geological model for roll-front development and supporting future exploration of underexplored segments.
Leadership Optimistic for Future Resource Potential
Colin Healey, CEO of Premier American Uranium, expressed strong encouragement with the program's outcomes. "We are highly encouraged with the results of the 2025 drilling program at Kaycee, which validated our thesis that the Project offers resource potential in a top U.S. uranium producing jurisdiction," Healey stated.
He highlighted that the program delivered a substantial number of holes with grades and thicknesses that typically support inclusion in a mineral resource estimate. This positive outcome is expected to inform the company's 2026 exploration plans, which are in final planning stages. Goals for the coming year include aggressive follow-up on new and known mineralized areas to determine resource potential, formally confirming historical resources, and testing high-priority targets identified from recent drilling.
The results from the Kaycee project underscore Premier American Uranium's ongoing efforts to consolidate and demonstrate value in its expanding portfolio of uranium assets in a leading North American production district.
