Premier American Uranium Expands Mineralization at Kaycee ISR Uranium Project in Wyoming Following 100,000+ ft Drill Program
Premier American Uranium Expands Mineralization at Kaycee ISR Uranium Project in
Wyoming Following 100,000+ ft Drill Program
TORONTO, January 20, 202 6 — Premier American Uranium Inc. (“PUR”, the “Company” or “Premier American
Uranium”) (TSXV: PUR) (OTCQB: PAUIF) is pleased to announce drill results from the 2025 drilling program at the
Company’s wholly-owned Kaycee ISR Uranium Project (“Kaycee” or the “Project”) located in the prolific Powder River
Basin (“PRB”) of northeastern Wyoming. The 2025 drilling campaign successfully advanced multiple targets, expanding
areas of known uranium mineralization in the Outpost, Rustler, and Stampede exploration areas, each associated with
major redox-controlled roll-front systems within the PRB. The Project is situated in the vicinity of several past and
presently producing ISR uranium operations, including Energy Fuels Inc.’s Nichols Ranch and Uranium Energy Corp .’s
Christensen Ranch ISR operations (Figure 1).
Highlights
• Drilling completed in 2025 includes 132 drillholes for a total of 100,107 ft.
• Follow-up drilling in the Outpost target area (Figure 2) during 2025 has confirmed the presence of a
newly defined uranium -bearing roll front system within Fort Union Formation channel sands. The
discovery builds upon positive drilling results from the Company’s late -2024 drilling program. Careful
and astute field observations by the Company’s geologists resulted in the recognition of remnant
uranium mineralization in up-dip exposures along the Pine Ridge escarpment and its relationship to more
robust mineralization down-dip, at the Outpost target area with the following results:
o Eleven of the 23 holes encountered uranium mineralization.
o Eight of the 11 mineralized holes encountered grades of 0.02% eU₃O₈ or greater with a thickness
of at least 2 ft (Table 1), including 3.5 ft of 0.27% eU₃O₈ in drillhole LT25-065 and 5.5 ft of 0.125%
eU₃O₈ in drillhole LT25-069.
• Drilling in the Rustler area further defined a previously identified north-south trending redox-front with
associated uranium mineralization hosted in Wasatch Formation channel sands. This 3.5 -mile corridor
represents one of the most laterally continuous redox interfaces in the project area, with the following
results:
o Twenty-two of the total 81 holes drilled in the Rustler area in 2025 encountered uranium
mineralization.
o Fifteen of the 22 mineralized holes encountered grades of 0.02% eU₃O₈ or greater with a
thickness of at least 2 ft (Table 1), including 8.5 ft of 0.083% eU₃O₈ in drillhole RT25-042 and 4 ft
of 0.09% eU₃O₈ in drillhole RT25-064. The mineralized holes confirm the continuity of previously
identified mineralization and are believed to demonstrate favourable host-sand characteristics
and geologic characteristics similar to the nearby Nichols Ranch ISR uranium project of Energy
Fuels Inc. less than five miles to the east.
• Mineralized intercepts encountered in the Stampede area during 2025 drilling (Table 1) demonstrate
continuity of the Wasatch-hosted redox trend between Stampede and Rustler, indicating that uranium
mineralization extends along a broad north–south corridor. This finding strengthens the regional model
for roll-front development and supports ongoing exploration targeting underexplored segments of the
redox trend.
Colin Healey, CEO of PUR commented, “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. The program delivered a substantial number of holes with grades and thicknesses exceeding those
typically necessary for incorporation into a mineral resource estimate, which we believe is very positive and bodes well
for our 2026 exploration plans at Kaycee which are in the final planning stages. Goals for 2026 at include aggressive
follow-up on newly identified and known mineralized areas to determine resource potential and formally confirming
historical resources at the Project, while also testing high-priority targets born from recent drill work. PUR continues
to establish a track record of successful consolidation of quality projects and rapidly demonstrating further value in
the expanding portfolio. I congratulate our growing team on our successes portfolio wide.”

Notes: Drill holes reported here encountered uranium mineralization with >2 -ft thickness at or above a cut -off grade of 0.02%
eU₃O₈.All grades were calculated from gamma-ray logs measured by Century Geophysics of Tulsa Oklahoma, which is independent
of the Company. The geophysical results are based on equivalent uranium (eU 3O8) of the gamma-ray probes which are calibrated
at the Department of Energy’s test facility in Casper, Wyoming. Uranium grades cited are calculated from gamma-ray logs, and the
cited grades are “equivalent” (“e”) grades of U₃O₈ %. eU₃O₈ is a measure of gamma intensity from a decay product of uranium
and is not a direct measurement of uranium. No corrections were made for radiometric disequilibrium. Numerous comparisons of
eU₃O₈ and chemical assays of PRB core samples indicate that eU₃O₈ is a reasonable indicator of the actual uranium assay. All drill
holes are vertical in orientation and the geologic units hosting the uranium mineralization are generally very flat lying, th erefore
reported thicknesses represent true thicknesses.

Kaycee Project
The Kaycee Project in Wyoming's Powder River Basin consists of over 42 square miles of mineral rights over a 36-mile
mineralized trend hosting more than 110 miles of identified roll fronts (Figure 3). The Project is believed to be the only
project in the PRB where all three known historically productive sandstone formations (Wasatch, Fort Union, and Lance)
are mineralized and potentially accessible for ISR extraction. The Project represents the larges t grass -roots ISR
exploration in the United States, with upwards of 400,000 ft of drilling completed since 2023.
PUR anchors one of the strongest exploration portfolios in Wyoming, combining its Cyclone Project in the Great Divide
Basin with Kaycee to drive one of the largest ongoing drilling programs in the state and significantly expand its presence
in both of the state’s major ISR-amenable uranium districts.
