American Uranium (ASX:AMU) has begun a phase one drilling program at the Lo Herma In-Situ Recovery (ISR) Project in the US, with the aim to grow the project’s resource.
The program will be completed in two phases, with the first phase comprising 50 holes for 15,000m and the second comprising 71 holes for 22,500m.
Phase one will focus on step-out drilling to expand the resource base by targeting known mineralised rollfronts in areas predominantly to the north of Mine Units 1 and 2.
Meanwhile, phase two – scheduled to begin early 2026 – will target an increase of the current proportion of indicated or measured categories within the mine units.
CEO Bruce Lane says the program marks a step towards advancing its near-term, low-cost ISR project.
“Lo Herma is one of the few new near-term, low-cost ISR projects in the US and the drilling campaign will target both growth in the current 8.57 million pounds resource base and increased confidence in mineral resources,” Lane says.
“This work is expected to feed into a further resource upgrade and updated Scoping Study in the first half of 2026 to demonstrate Lo Herma’s potential to deliver similar economic potential to ISR uranium mines currently being planned or constructed in Wyoming such as Ur-Energy’s Shirley Basin Project.”
The Lo Herma Project is located in Converse County in the Powder Basin River of Wyoming. The Powder River Basin has extensive ISR uranium production history with numerous defined ISR uranium resources, central processing plants, and satellite deposits.
