• Secured ~1,040 acres of new uranium mineral rights adjacent to existing Mine Units 2 and 3
• Staked 29 new federal lode mining claims covering ~490 acres
• Expanded land position enhances exploration potential and Mine Unit optionality

American Uranium Ltd (ASX:AMU; OTCQB:AMUIF) has expanded the Lo Herma ISR Uranium Project in Wyoming's Powder River Basin by securing strategically located uranium mineral rights and staking additional mining claims. The expanded land position secures highly prospective ground adjoining the proposed Mine Units and enhances exploration and development flexibility. The company has secured approximately 1,040 acres of new uranium mineral rights located to the north and immediately south abutting Mine Unit 2 and to the north abutting Mine Unit 3, extending AMU's control over highly prospective portions of the Lo Herma roll-front systems. Importantly, the new mineral rights abutting the south of Mine Unit 2 and the north of Mine Unit 3 adjoin existing mineral resource areas. In parallel, AMU has staked 29 new federal lode mining claims, covering approximately 490 acres, extending the land position and providing a buffer along areas identified as highly prospective for additional roll-front uranium mineralisation. The expanded land position enhances the exploration and development potential of the Lo Herma Project by securing land tenure immediately adjacent to proposed Mine Units, extending control along interpreted mineralised trends, allowing future optimisation of Mine Unit boundaries and ISR wellfield design, and supporting further growth in Mineral Resources and Exploration Targets. Drilling of the remaining 55 permitted infill and expansion holes is anticipated to commence by early May 2026, including step-out drilling into the newly secured area south of Mine Unit 2.

Subject to the completion of the upcoming drilling program and technical evaluation, the Company intends to deliver an updated Mineral Resource Estimate and Scoping Study during Q3 2026.
