TORONTO, July 13, 2026 (GLOBE NEWSWIRE) -- Premier American Uranium Inc. ("PUR", the "Company" or "Premier American Uranium") (TSXV: PUR) (OTCQB: PAUIF) is pleased to announce the successful completion of its drilling program at the Company's wholly owned Cebolleta Uranium Project ("Cebolleta" or the "Project") in New Mexico. As announced in a press release on May 12, 2026, the program was designed to recover representative samples from the underground resource area to support advanced technical studies as part of the Company's 2026 work program focused on advancing process optimization and Project economics. The recovered samples have now been delivered to Hazen Research, Inc. ("Hazen Research"), the Company's contracted metallurgical laboratory in Golden, Colorado, where they will support a planned comprehensive metallurgical testing program aimed at optimizing heap-leach uranium recovery and informing key assumptions for future economic studies including a planned update to the Company's current Preliminary Economic Assessment with respect to the Project (the "2025 PEA") targeted for completion in 2027.
Highlights
Representative Drill Program Successfully Completed: Completion of a 6,030-foot PQ-core drilling program. Core drilling occurred at four locations targeting mineralization representative of the underground mining portion of the Company's current Mineral Resource Estimate ("MRE") for the Project included in the 2025 PEA. To obtain sufficient sample volume for metallurgical tests, mineralized core was collected from a total of 18 vertical holes (4 to 6 per location) with results summarized in Table 1. Downhole gamma results are generally consistent with historic drilling and the Company's 2023 confirmation drilling program and will be added to the drilling database for the planned updated MRE in the 2027 PEA.
Metallurgical Samples Delivered to Hazen Research: Delivery of 77 core samples to Hazen Research. Combined mineralized PQ-core samples totaled 282.6 feet (85.9 m) and 2,124 pounds (963.3 kg). Selection of core samples was guided by handheld scintillometer readings in a sterile background combined with downhole gamma results, utilizing a cutoff grade of 0.06% eU3O8, the underground mining cut-off grade used in the 2025 PEA.
High Sample Recovery Enables Expanded Metallurgical Testing Program: Drilling conditions achieved 97% footage recovery in mineralized zones and an overall mass recovery of 90%, exceeding the target sample mass of 800 kg by 20%. The recovered material provided representative samples for the planned metallurgical test program. Sample preparation by Hazen Research is underway, and the Company anticipates the extra sample material will facilitate additional laboratory tests including density, chemical disequilibrium, and a larger suite of geochemical analyses.
