Premier American Uranium Reports Initial 2026 Drill Results and Expands Uranium Mineralization at Kaycee Project
Premier American Uranium Inc. announced preliminary results from the 2026 exploration drilling program at the Company’s wholly-owned Kaycee Project, located in the Powder River Basin of northeastern Wyoming. Drilling commenced at the Outpost target in May 2026. To date, 19 drillholes have been completed for a total of 17,100 ft of drilling. A total of 100,000 ft of drilling is currently planned for the 2026 season, with specific focus on the Outpost, Rustler, and Stampede exploration areas. Infill and step-out drilling in the Outpost area has expanded and further defined the zone of known uranium mineralization. Nineteen conventional mud rotary holes have been completed for a total of 17,100 ft of drilling in 2026. Seven of the 19 drill holes intersected uranium mineralization at grades of 0.02% eU3O8 or higher. Drilling results to date provide valuable lithologic information to support geologic interpretation and guide future exploration plans. Drilling has identified two target sand units within the lower Wasatch Formation, both of which are host to uranium mineralization. The lower Wasatch Formation is also the principal host of uranium mineralization in the Pumpkin Buttes district, just east of the Kaycee Project area. In conjunction with the drilling program, the Company engaged a professional surveying contractor to complete a Project-wide drillhole collar and elevation survey. This survey work is complete, and the results will be used to support future mineral resource estimation initiatives and ongoing technical evaluation of the Project. Drill holes reported here encountered uranium mineralization at or above a cut-off grade of 0.02% eU3O8. All grades were calculated from gamma-ray logs measured by Hawkins CBM Logging of Casper, Wyoming, which is independent of the Company. The geophysical results are based on equivalent uranium (eU3O8) 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, therefore reported thicknesses represent true thicknesses. 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. 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 largest grass-roots ISR exploration in the United States, with upwards of 400,000 ft of drilling completed since 2023. The scientific and technical information contained in this news release was reviewed and approved by J.J. Brown, P.G., SME-RM, PUR’s Vice President, Exploration, who is a “Qualified Person” as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects. Ms. Brown has verified the data disclosed in this news release, including sampling, analytical, and test data underlying the information contained herein. The drilling results cited in this news release were derived from conventional mud rotary drill holes and continuously recorded geophysical responses (gamma-ray, spontaneous-potential, and single point resistivity) from a borehole geophysical probe. The mineralized zones are flat lying and the individual drill holes are vertical in orientation, and the thicknesses cited in this release are considered to be true thicknesses. Grades of mineralization reported were calculated from the gamma-ray logs following a procedure that was first developed in the early 1960s and is standard practice in the uranium industry. The borehole geophysical logging was carried out by Hawkins CBM Logging of Casper, Wyoming, a highly experienced and skilled geophysical contractor with a well-established history of providing reliable and accurate data.
