USA Uranium's flagship Mesa Top Mine Project is a past-producing uranium property in New Mexico's Grants Mineral Belt, historically the most productive uranium district in the US. The property is 100% owned and you can drive to it. It sits on federal land near established infrastructure, and it covers two historic underground mines that produced high-grade ore for nearly three decades. With US policy now prioritizing a secure domestic nuclear fuel supply, Mesa Top gives USA Uranium a proven starting point. The company plans modern exploration to turn this history into a defined resource, with vanadium and molybdenum as added upside. Historic production is not a current mineral resource. The project is at the exploration stage.
The Mesa Top Mine Project is USA Uranium's flagship property. It is a past-producing uranium project in McKinley County, northwestern New Mexico, within the Ambrosia Lake subdistrict of the Grants Mineral Belt. The Grants Mineral Belt lies on the Colorado Plateau. It is the largest uranium area in the United States and supplied roughly 40% of all historic domestic uranium production. USA Uranium holds a 100% interest in the project. The company sees Mesa Top as a proven platform for modern exploration aimed at defining a compliant mineral resource.
The property consists of 24 active lode claims covering about 496 acres of land administered by the Bureau of Land Management, in Section 20, Township 13 North, Range 9 West. The claims form a single contiguous block covering most of the 640-acre survey section. They are in good standing, with maintenance fees paid through September 1, 2027. The property can be reached by road and lies close to state highways and to the infrastructure that supported decades of mining across the Ambrosia Lake area. This keeps exploration practical and cost-efficient.
Two historic underground mine complexes sit on the claims. Between 1954 and 1968, the Mesa Top Mine produced 108,261 tons of ore at an average grade of 0.24% U₃O₈, roughly 520,000 pounds of uranium oxide. The nearby Dog Group Mines operated from 1957 to 1980 and produced 244,177 tons of ore at an average grade of 0.19% U₃O₈, roughly 928,000 pounds. Together, recorded production from the property totals about 352,000 tons of ore and 1.45 million pounds of U₃O₈ over nearly three decades. That history means exploration can start from known mineralization and existing workings rather than untested ground.
Uranium at Mesa Top is hosted in sandstones of the Jurassic Morrison Formation, the main host for uranium deposits throughout the Grants Mineral Belt. These sediment-hosted systems formed most of the district's historic deposits and remain the main exploration target in the region. The same host rocks are also prospective for vanadium and molybdenum, which gives the project possible by-product value alongside uranium.
Mesa Top combines a top-tier uranium district, a documented production record, secure federal-land tenure, and practical road access. It also benefits from US policy that increasingly prioritizes a secure domestic nuclear fuel supply, and the Grants Mineral Belt is well placed to help meet that demand. For USA Uranium, the project is a de-risked starting point: past production confirms the mineral system, and modern exploration methods give it a clear path to new value.
The project is at the exploration stage. The company's first priorities are to compile and verify the historic records, then use that data to target drilling around the known mine areas. The longer-term goal is to define a current mineral resource that meets modern disclosure standards, with vanadium and molybdenum assessed as part of that work.
The Mesa Top Mine Project gives USA Uranium a foothold in the Grants Uranium District of McKinley County, New Mexico, historically the most productive uranium district in the United States. The property sits in a region with decades of documented mineralization, established geological models, and existing infrastructure, which gives exploration a proven geological setting to work from rather than starting at grassroots level.
The timing matters as much as the location. U.S. nuclear energy policy, growing electricity demand from data centres and AI infrastructure, and a national push to reduce reliance on foreign uranium supply are all raising the strategic value of domestic assets. Mesa Top puts USA Uranium in a position to contribute to a secure American fuel cycle at a time when supply is tight and demand is rising.
With a defined 24-month exploration program, USA Uranium plans to advance Mesa Top methodically. The work will start with compiling historical data and moves through modern geophysics, drilling and resource definition. The objective is clear: unlock the value of a proven district with modern exploration methods and build a high-quality domestic uranium asset for the next generation of American energy.
