Premier American Uranium Identifies Multiple Mineralized Uranium Trends in Ongoing Drilling at Kaycee, Wyoming

TORONTO, Aug. 17, 2026 (GLOBE NEWSWIRE) — Premier American Uranium Inc. (“PUR”, the “Company” or “Premier American Uranium”) (TSXV: PUR) (OTCQB: PAUIF) is pleased to report encouraging mid-season results from its ongoing 100,000-foot 2026 exploration drilling program at the Company’s wholly-owned Kaycee Project (“ Kaycee ” or the “ 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 (Figure 1).

Colin Healey, CEO of PUR commented, “We’re seeing good success from our 2026 program at Kaycee, with nearly half of the planned 100,000 feet of drilling now complete. With approximately 430 miles of interpreted roll fronts, we believe we are just beginning to unlock the potential of this large mineralized system. This year’s drilling is focused on systematically testing that potential, identifying the extents of mineralization in the targeted areas and identifying the areas with the greatest opportunity to build pounds. The results at Rustler are particularly encouraging, with mineralization identified in two distinct sandstone units and indications of potentially stacked roll fronts. As we continue drilling, our goal is to advance these mineralized trends and build the geological understanding needed to ultimately define a meaningful uranium resource at Kaycee.”
