American Uranium (ASX:AMU) announced the imminent commencement of a drilling programme at its flagship Lo Herma ISR Uranium Project in Wyoming’s Powder River Basin.
Scheduled to begin in early May, the campaign marks a critical milestone in the company’s strategy to expand and de-risk the asset ahead of a major resource update.
The upcoming phase focuses on completing the remaining 55 holes of a 121-hole permitted programme, following the successful completion of 66 holes during previous campaigns.
The programme is dual-purposed, involving infill drilling within the established Mine Unit 1 to improve geological confidence and expansion drilling into high-prospectivity zones recently secured south of Mine Unit 2.
Executive Director Bruce Lane emphasised that these efforts are designed to test mineralised trends and upgrade resources, ensuring a robust foundation for the scoping study and mineral resource update slated for Q3 2026.
In addition to the drilling, the company will run parallel hydrogeological and metallurgical work programmes.
The technical studies are vital for refining parameters such as formation permeability and leach test characteristics, which underpin the assumptions for in-situ recovery development.
By integrating this field data into their technical evaluations, American Uranium aims to streamline the transition from exploration to development.
At the time of reporting, American Uranium’s share price was $0.12.
