American Uranium pumps Lo Herma towards development

American Uranium (ASX:AMU) is testing one of the things that could make or break an in situ recovery (ISR) uranium project: how the aquifer behaves.

Executive Director Bruce Lane says large-scale pump testing is underway at Mine Unit 1 of the flagship Lo Herma ISR Project in Wyoming, US, gathering the flow and permeability data needed to help shape future wellfield design and the upcoming Scoping Study.

  • Pump test: Mine Unit 1 is the focus
  • Aquifer check: Testing transmissivity and permeability
  • Hard data: Results will feed into mine design assumptions
  • Next milestone: Scoping Study targeted for Q4
  • Permitting: Hydrogeological work also supports future aquifer permits

No pit. No giant shovel. Just a lot riding on how the water moves.

About the guest and company:
Bruce Lane is the executive director of American Uranium, an ASX-listed uranium explorer and developer focused on US projects suited to ISR. Its flagship Lo Herma Project is in Wyoming’s Powder River Basin, with the company also holding uranium projects elsewhere in Wyoming and Utah. 

Disclosure: Mining.com.au may hold shares in American Uranium.

🎥 Watch the full interview to see why pump testing is a key step in moving Lo Herma towards development.
