The Company controls a significant land position of approximately 26,180 acres of mineral rights within the western and southwestern parts of the Great Divide Basin.
The Cyclone project has good potential for the discovery of uranium deposits that would be amenable to in-situ recovery (ISR) methods. The project is located approximately 45 miles northwest of Rawlins, Wyoming, and 15 miles from the Lost Creek ISR Central Processing Plant and Sweetwater Uranium Mill. The project area spans 1,161 claims encompassing 21,900 acres, along with 9 state leases and an additional 4,280 acres.
The uranium deposits in the basin are hosted in roll-front deposits of the Battle Spring Formation, with a widespread alteration of host sandstones and numerous roll-front uranium deposits associated with altered rocks.
Previous exploration on the project includes ~80 holes drilled during 2007-2008, with mineralization showing typical grades and thicknesses to uranium deposits found elsewhere in the Great Divide Basin. Intersections from exploration on the Rim Target (North claim block) include hole UT-8 which intersected 8.0 ft. averaging 0.092% eU3O8 (0.02% cut-off) or 5.5 ft. @ 0.121% eU3O8 at 200 feet from the surface and hole UT-44 which intersected 7.5 ft. averaging 0.081% eU3O8 (0.02% cut-off grade) or 5.5 ft. averaging 0.104% eU3O8 at a 0.05% cut-off grade.
In 2025, Premier American Uranium completed a 25-hole, 17,160-foot exploration program at the Cyclone Rim target that extended the existing half-mile mineralized trend and identified a new 1.5-mile mineralized corridor that remains open.
Thirteen holes returned significant uranium mineralization (>0.01% eU₃O₈), including 15.5 feet grading 0.09% eU₃O₈, including 3.0 feet grading 0.229% eU₃O₈, representing the best-known uranium-mineralized intercept identified at the project to date.
At the Osborne Draw target, preliminary drilling totaling 4,200 feet encountered uranium mineralization in four of five drill holes, with three holes intersecting multiple mineralized zones. Individual drill intercepts returned up to 0.021% eU₃O₈ over 24.5 feet (GT of 0.51).
Results from both target areas highlight the resource potential of the project and provide a breadth of data to generate high-potential targets for future drilling.
1. As determined by BRS Engineering, sufficient historical exploration data is available for the North and East claim blocks to define an exploration target , which shows a range of 6.5 million short tons averaging 0.06% U3O8 (7.9 million lbs. U3O8) to 10.5 million short tons averaging 0.06% U3O8 (12.6 million lbs. U3O8).1The potential quantity and grade of this exploration target is conceptual in nature and based on the geologic interpretation that mineralization is Sandstone Type mineralization, aerial radiometric anomalies, and indications of the presence of oxidation reduction interfaces with mineralization from available drill data. There has been insufficient exploration to define a mineral resource, and it is uncertain if a mineral resource will be delineated. For the definition of the exploration target, the following criteria based on direct knowledge and experience in the area and similar sandstone hosted uranium deposits in Wyoming was used: (i) a minimum cut-off grade of 0.02% U3O8 and a grade thickness product (GT) of 0.10, (ii) a radiometric disequilibrium factor of 1, and (iii) a bulk density of 16 cubic feet per ton.
