Mesa Top isn't a grassroots bet. It's a past-producing underground mine that yielded about 571,000 lbs of U₃O₈ from 108,261 tons of ore between 1954 and 1968. USA Uranium is starting with proven mineralization, existing workings and decades of historical data.
USA Uranium holds a 100% interest in the Mesa Top Mine Project. The property is on BLM land, reachable by road and close to major state highways. Full ownership means shareholders get all of the upside, and the existing access cuts the time and cost of putting crews and drill rigs on site.
Historical ore at Mesa Top averaged 0.24% U₃O₈ and was hosted in the Poison Canyon Sandstone, one of the Grants Belt's proven uranium-bearing units. The property also has vanadium and molybdenum potential. That gives USA Uranium more than one way to add value.
Mesa Top sits in the Ambrosia Lake subdistrict of the Grants Mineral Belt. That belt once produced about 40% of all U.S. uranium, and 409 million lbs of identified resources are still in the ground there. USA Uranium (CSE: USUR, OTC: USURF) gives investors a direct stake in America's most productive uranium district.
The program opens by compiling, digitizing and reinterpreting decades of historical exploration data from the Grants Uranium District, one of the most productive uranium regions in U.S. history. In parallel, the team finalizes claim maintenance and title work, starts permitting with the relevant state and federal agencies, and begins working with local communities, landowners and stakeholders in McKinley County. This phase sets the technical, legal and social groundwork for everything that follows, so fieldwork can start without delays.
With the groundwork done, exploration moves into the field. High-resolution airborne radiometric and magnetic surveys give a property-wide picture of radioactivity and structural controls. Ground geophysics, detailed geological mapping and systematic surface sampling then follow up on those results. All of this is combined with the historical record in a modern 3D geological model, which produces a ranked list of high-confidence drill targets. The goal is to put every drill metre where it is most likely to add value.
Phase 1 drilling tests the highest-priority targets and confirms the historical mineralization at Mesa Top to modern standards. Every hole is logged with downhole gamma probes for real-time grade estimates, and core and chip samples go to accredited labs for chemical assays. Results confirm the grade, thickness and continuity of the mineralized horizons. This creates the verified data needed for a compliant resource and gives investors a steady flow of news.
Building on Phase 1, step-out drilling extends the known zones along strike and at depth, while infill drilling tightens hole spacing to improve geological confidence. Early metallurgical testwork looks at recovery characteristics and possible processing routes, including in-situ recovery where the geology allows it. Environmental baseline studies on water, soils, wildlife and cultural resources begin at the same time, so the project is ready for future permitting and development decisions.
The program ends with a maiden NI 43-101 mineral resource estimate prepared by independent qualified persons, turning two years of work into a defined, bankable asset. With a quantified resource, USA Uranium can lay out next-stage development plans, move toward a preliminary economic assessment, and approach strategic partners, offtakers and financiers. Mesa Top is then positioned as a domestic uranium supply source at a time of rising demand for secure American nuclear fuel.
