American Uranium (ASX:AMU) has strengthened its foothold in Wyoming's Powder River Basin, announcing a substantial expansion of its flagship Lo Herma ISR Uranium Project.
By securing approximately 1,040 acres of new uranium mineral rights and staking 29 additional federal lode mining claims, the company has successfully consolidated its land position around the critical mine units 2 and 3.
The strategic move directly addresses previous land tenure constraints, allowing the company to capture highly prospective ground that was formerly restricted by boundary limitations.
Executive Director Bruce Lane emphasised that this expansion is not merely about acreage but about unlocking resource growth.
"Our current dataset suggests this new ground holds real potential to contribute to the future resource footprint," Lane noted, highlighting that the new parcels adjoin existing mineralised trends.
The expanded footprint provides enhanced exploration flexibility and "mine unit optionality", which is vital for the in-situ recovery process.
Investors can look forward to immediate operational momentum, with a 55-hole drilling programme scheduled to commence in early May.
The campaign will include exploration of a new area south of Mine Unit 2.
Following the completion of this drilling and subsequent technical evaluations, American Uranium aims to deliver an updated mineral resource estimate and scoping study during the third quarter of 2026.
At the time of reporting, American Uranium’s share price was $0.13.
