Premier American Uranium Successfully Completes Drilling Program at Cebolleta Project, New Mexico and Delivers Samples for Advanced Metallurgical Testing

Premier American Uranium Inc. (PUR) has completed a 6,030-foot PQ-core drilling program at its Cebolleta Uranium Project in New Mexico. The company delivered a total of 77 core samples, totaling 282.6 feet (85.9 meters), to Hazen Research for a comprehensive 42-week metallurgical testing program. These tests will include bottle roll and column leach procedures designed to optimize heap-leach uranium recovery.

Premier American Uranium notes that increasing metallurgical recovery from 80% to 90% could raise the after-tax net present value (NPV) of the 2025 preliminary economic assessment (PEA) by approximately 90%, from US$84 million to US$159 million, pending validation. Downhole gamma results from the new drilling are consistent with historic drilling and the 2023 confirmation program. The company plans to utilize the extra sample material for additional laboratory tests, including density, chemical disequilibrium, and geochemical analyses.

Premier American Uranium Inc. (PUR) has completed its drilling program and delivered samples, marking a direct follow-up to the March 2026 work program announcement and the December 2025 Preliminary Economic Assessment (PEA). The metallurgical optimization pathway was already factored into market expectations as a key upside lever in the 2025 PEA.

The announcement introduces no new financial metrics, strategic shifts, or unexpected operational milestones, serving instead to confirm the execution of a previously disclosed plan. While the potential net present value (NPV) uplift to $159 million remains speculative, this valuation is contingent on test results that are not expected to be validated until late 2026 or early 2027.

Premier American Uranium Inc. (TSXV: PUR) is a pre-revenue U.S. uranium exploration and development company. Its flagship asset is the Cebolleta Uranium Project in New Mexico, located in the Grants Mineral Belt with existing infrastructure and paved road access.

According to the 2025 Preliminary Economic Assessment, the project features a 13-year mine life with an average production of 1.4 million pounds of U3O8 per year, peaking at 2.0 million pounds. At a uranium price of $90 per pound, the project yields an after-tax net present value of $83.9 million at an 8% discount rate and an internal rate of return of 17.7%, with direct capital expenditures of $64.2 million.

The company also holds the Kaycee ISR Project and the Cyclone ISR Project in Wyoming, which were acquired through the Nuclear Fuels merger in September 2025. Premier American Uranium Inc. focuses on the consolidation, exploration, and development of U.S. uranium assets to revitalize domestic production.
