Positive Drill Results From The Cyclone ISR Project

TORONTO – Premier American Uranium Inc. (PUR) reported positive drill results from the ongoing exploration drilling program on the Cyclone Rim target at the Company’s wholly-owned Cyclone ISR Uranium Project, located in the Great Divide Basin of south-central Wyoming. The exploration program commenced in July, with the objective of further defining sandstone-hosted uranium mineralization that was partially outlined during the Company’s 2024 exploration program. The Project is situated in the vicinity of Ur-Energy Inc.’s Lost Creek ISR uranium mine and other former uranium production facilities.
Positive drill results include mineralized zones encountered in areas where uranium mineralization was not previously known to occur, and extensions of known mineralization along a previously identified geologic trend. Fourteen of 25 planned conventional (mud) rotary holes have been completed thus far, for a total of 10,600 ft of drilling in 2025. Eight of the 14 drill holes completed to date intersected uranium mineralization at grades of 0.01% eU₃O₈ or higher (see Table 1 for complete results). Notably, hole CR25-001 returned 15.5 ft grading 0.09% eU₃O₈. Within the overall mineralized zone is a three-foot thick zone that averages 0.229% eU3O8. Drilling at the Cyclone Rim target in 2024 identified flat lying uranium mineralization along a ½-mile, east-west trend. The 2025 drilling program has extended that mineralized trend and has identified a potential second trend of uranium mineralization running north-south over a 1.5-mile distance. Both mineralized zones remain open in multiple directions and are expected to be a continued focus of the 2025 drill campaign.
Colin Healey, CEO said, “We are encouraged by the strong results emerging from drilling at Cyclone Rim. With each phase, our understanding of the mineralized system improves, and we remain focused on expanding known zones of mineralization while also uncovering new areas of potential mineralization. As results continue to come in throughout the summer, we are actively evaluating the opportunity to expand the scope of the 2025 program to include additional drilling. I congratulate our technical team on the strong execution in the field thus far.”
