The Company controls a significant land position of approximately 25,500 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, and 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 1,061 claims encompassing 21,220 acres, along with 7 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. Exploration potential is high for the project with drilling required to follow up on results from the 2024 inaugural drill program.
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 October 2024, Premier American Uranium completed a 41-hole, 20,990-foot exploration program at the Cyclone Rim target that confirmed uranium mineralization along a roughly half-mile, east-west trend. This zone remains open in multiple directions and includes intercepts of up to 0.088% eU₃O₈ over 10.5 feet (Grade Thickness, or GT, of 0.92). Anomalous uranium mineralization (>0.01% eU₃O₈) was identified in 11 holes, with five returning GT intercepts of 0.20 or higher.
Drilling at the Osborne Draw target began ahead of schedule, with five of 36 planned holes (totaling 4,200 feet) already completed. Uranium mineralization was encountered in four of the five initial holes, with multiple mineralized zones in three. Notably, one intercept returned 0.021% eU₃O₈ over 24.5 feet (GT of 0.51). The majority of drilling at Osborne Draw is expected to take place in 2025.
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.
