American Uranium (ASX:AMU | OTC:AMUIF) commences resource drilling ahead of schedule at Lo Herma

American Uranium (ASX:AMU | OTC:AMUIF) has moved swiftly to advance its flagship Lo Herma in-situ recovery (ISR) uranium project in Wyoming’s Powder River Basin, mobilising a drill rig ahead of schedule to begin a two-phase resource development program.

The initiative targets both expansion of the existing 8.57 million pound uranium resource and upgrading of mineral resource classifications across proposed mine units.

Highlights

• Drill rig mobilised earlier than planned to commence resource drilling at Lo Herma.

• Phase 1 expansion program underway this week, focusing on growing the 8.57Mlb resource base.

• Interim Mineral Resource Estimate (MRE) update expected in early 2026.

• Phase 2 infill drilling planned for Q1 2026 to upgrade resource confidence levels ahead of an updated Scoping Study.

• Permits, bonds, and site access fully secured, with allowance for up to 121 drill holes and 37,500 metres of drilling across Mine Units 1 and 2.

Located within the heart of Wyoming’s established uranium province, Lo Herma is positioned as one of the few near-term, low-cost ISR uranium projects in the United States.

ISR mining, a method of extracting uranium via solution mining, offers cost and environmental advantages compared to conventional mining, making it a preferred approach for U.S. developers seeking domestic supply chain security.

The company’s first phase of drilling, totalling approximately 50 holes for 15,000 metres, will focus on step-out exploration aimed at enlarging the existing mineral resource by targeting known mineralised rollfronts to the north of Mine Units 1 and 2.

A second phase, scheduled for early 2026, will include around 71 holes for 22,500 metres and is designed to upgrade a greater proportion of the current resource to the Indicated and Measured categories, thereby increasing geological confidence and supporting future feasibility work.

CEO and Executive Director Bruce Lane said the early commencement of the campaign underscores the company’s operational readiness and strategic focus.

“We are very pleased to be commencing Phase 1 of the resource development drilling campaign at Lo Herma ahead of schedule. We’re excited to be in a strong position to be able to complete this first phase of resource expansion drilling this quarter, with an interim mineral resource estimate update expected in early 2026,” he said.

Lane added that the program represents a major step towards developing one of America’s most promising ISR projects, and that results from this phase are expected to feed into an upgraded resource and revised Scoping Study in the first half of 2026.

American Uranium’s permit, allowing for up to 121 holes and 37,500 metres of drilling, reflects a methodical approach to growth.

The structured program not only targets volumetric expansion but also the technical upgrading of resources, which is critical to underpin economic modelling and future development decisions.

The company’s progress at Lo Herma comes amid renewed attention on uranium markets, driven by increasing energy security concerns and the global pivot toward nuclear as a reliable low-emission power source.

By advancing one of the few ISR projects in late-stage development, American Uranium positions itself to contribute meaningfully to the U.S. domestic uranium supply chain.

With drilling underway ahead of schedule, a resource update slated for early 2026, and an upgraded Scoping Study to follow, the months ahead are shaping up to be formative for American Uranium’s push to deliver an ISR project aligned with the new era of nuclear power demand.
