Resource Expansion Drilling Confirms 3,000 metres of New Uranium Trends with Best Drill Hole of 1.4 GT over 7.6 metres

The resource expansion drilling and recently completed pump testing program2 represent significant steps in the efforts to expand and upgrade the resource and validate aquifer transmissivity to support Lo Herma’s progression towards ISR mine development.

Highlights

• Fifty (50) resource expansion drill holes, for ~16,300m (53,460ft), completed for 2025
• Drilling confirms projected uranium mineralised trends north of proposed Mine Units 1 and 2 by up to 3000 metres (10,000 feet) from mineralised drill holes
• Best mineralised intercepts reported include 4.1m (3.5ft) at 0.078% (780ppm) eU₃0₈ containing 1m (3.5ft) at 0.143% (1,430ppm) eU₃0₈ in hole LH-25-048
• Best total hole GT¹ of 1.41 over 7.6m (25 ft) in 2 stacked sand units in LH-25-048
• Planned Mineral Resource Estimate update and further drilling anticipated in 2026
• Twelve (12) new mineral claims secured, totalling 96 hectares (238 acres) staked to extend the project north of proposed Mine Unit 2
• Hydrogeologic and drilling programs aim to de-risk and advance the Lo Herma ISR Project towards a planned 2026 Scoping Study update

Speaking about the drill results, American Uranium’s CEO and Executive Director Mr Bruce Lane commented: “We are delighted that this resource expansion drilling has delivered strong grades with generous thicknesses in multiple stacked sands of both the Wasatch and the Fort Union formations. We remain very optimistic that the results of this expansion drilling campaign at Lo Herma can be brought into additional resource pounds. This year’s drilling has successfully demonstrated that the host sandstone units contain reliable continuity of mineralisation across extended trends for 3km (10,000ft) to the north of the current proposed mine units. With resource expansion drilling now completed for 2025, we look forward to the full geological evaluation of these results in early 2026 ahead of the next phase of drilling. Petrotek’s hydrogeological testing report is expected shortly which, along with the latest drilling data, will help guide the next steps of project development.

“AMU continues to both grow and de-risk the Project as we progress toward an update of the Lo Herma Scoping Study in 2026.”
