Premier American Uranium Reports Encouraging Mid-Season Results from Ongoing Exploration Drilling Program At Kaycee Project in Wyoming
Premier American Uranium Inc. has reported encouraging mid-season results from its ongoing 100,000-foot 2026 exploration drilling program at the Company’s wholly-owned Kaycee Project in Wyoming’s Powder River Basin. Since drilling commenced in early May, 50 conventional mud-rotary drillholes totaling 41,960 feet have been completed across the Rustler and Outpost target areas, representing approximately 42% of the planned 100,000-foot program. Thirteen of 22 holes drilled in the Rustler target area (drill holes RT26-082 through RT26-104) encountered uranium mineralization at grades of 0.02% eU3O8 or higher. Notably, hole RT26-085 intersected 3.5 ft grading 0.135% eU3O8, including 2 ft grading 0.204% eU3O8, confirming the presence of uranium mineralization within the system. Drilling has confirmed uranium mineralization within two separate sandstone units in the lower Wasatch Formation, the principal host formation for uranium deposits in the adjoining Pumpkin Buttes mining district. Uranium mineralization has been encountered in both sands, and gamma ray borehole geophysical log results indicate possible stacked roll fronts in the upper unit. Oxidation states of the two sandstone units indicate that the two mineralized systems are independent of one another, with the redox boundary in the lower sand unit well to the east of the redox boundary in the upper sand, providing multiple prospective trends for ongoing exploration. Seven of 27 holes completed (drill holes LT26-074 through LT26-100) at the Outpost target encountered uranium mineralization grading 0.02% eU3O8 or higher. Combined 2025 and 2026 results at Rustler are providing an increasingly detailed picture of subsurface channel geometry and associated mineralized trends. Radiometric assay results and borehole geophysical data are being incorporated in real time to refine the geological model and guide subsequent drill locations. The 2026 Kaycee Significant Intercepts include: LT26-074 intersected 214.5-215.5 ft, 1 ft, 0.052% eU3O8 and 798.5-800.5 ft, 2 ft, 0.036% eU3O8; LT26-076 intersected 802-805 ft, 3 ft, 0.022% eU3O8 including 803-804.5 ft, 1.5 ft, 0.03% eU3O8; LT26-077 intersected 792.5-794.5 ft, 2 ft, 0.073% eU3O8 including 793-793.5 ft, 0.5 ft, 0.101% eU3O8; LT26-078 intersected 748-749 ft, 1 ft, 0.029% eU3O8; LT26-079 intersected 771.5-772.5 ft, 1 ft, 0.022% eU3O8 and 787-789 ft, 2 ft, 0.027% eU3O8; LT26-083 intersected 773-774 ft, 1 ft, 0.026% eU3O8; LT26-086 intersected 793-793.5 ft, 0.5 ft, 0.026% eU3O8; RT26-082 intersected 374-378.5 ft, 4.5 ft, 0.034% eU3O8; RT26-083 intersected 374.5-375 ft, 0.5 ft, 0.02% eU3O8 and 380-382 ft, 2 ft, 0.046% eU3O8; RT26-085 intersected 408-411.5 ft, 3.5 ft, 0.135% eU3O8 including 408.5-410.5 ft, 2 ft, 0.204% eU3O8; RT26-089 intersected 393-395 ft, 2 ft, 0.047% eU3O8 including 393.5-394 ft, 0.5 ft, 0.07% eU3O8 and 444.5-446.5 ft, 2 ft, 0.022% eU3O8 including 445-446.5 ft, 1.5 ft, 0.025% eU3O8 and 662.5-663.5 ft, 1 ft, 0.023% eU3O8 and 671-672.5 ft, 1.5 ft, 0.027% eU3O8 and 675-676 ft, 1 ft, 0.023% eU3O8; RT26-090 intersected 381.5-386.5 ft, 5 ft, 0.03% eU3O8 including 382.5-386 ft, 3.5 ft, 0.038% eU3O8; RT26-092 intersected 674.5-678 ft, 3.5 ft, 0.064% eU3O8 including 675.5-676.5 ft, 1 ft, 0.11% eU3O8; RT26-093 intersected 433-435 ft, 2 ft, 0.018% eU3O8 including 434-434.5 ft, 0.5 ft, 0.02% eU3O8; RT26-094 intersected 431-435.5 ft, 4.5 ft, 0.043% eU3O8 including 431.5-433.5 ft, 2 ft, 0.068% eU3O8 including 432-432.5 ft, 0.5 ft, 0.103% eU3O8; RT26-096 intersected 673-677 ft, 4 ft, 0.032% eU3O8 including 674-676 ft, 2 ft, 0.037% eU3O8; RT26-101 intersected 379-381 ft, 2 ft, 0.033% eU3O8; RT26-102 intersected 423-424.5 ft, 1.5 ft, 0.021% eU3O8; RT26-103 intersected 426-427.5 ft, 1.5 ft, 0.029% eU3O8 and 434.5-435.5 ft, 1 ft, 0.023% eU3O8; RT26-104 intersected 389.5-391 ft, 1.5 ft, 0.029% eU3O8 and 392-396 ft, 4 ft, 0.041% eU3O8 including 395-395.5 ft, 0.5 ft, 0.068% eU3O8.
