Large-Scale Aquifer Testing Commences at Lo Herma

• Major milestone: Large-scale aquifer testing has begun at Lo Herma Mine Unit 1.
• Key hydrogeological data collection: Designed to assess groundwater flow and connectivity.
• Follows recent resource update: AMU's 9.96Mlb resource update in August 2026.

American Uranium Limited (ASX:AMU) has initiated large-scale hydrogeological pump testing at its Lo Herma ISR Uranium Project in Wyoming. This program, centered around the existing LH MW-003 pumping well, is designed to generate key hydrogeological data for groundwater modeling, permitting activities, and future ISR wellfield design. The testing follows AMU's recent 9.96Mlb resource update, which includes 7.38Mlbs U3O8 within the proposed Scoping Study area. Results from the testing program are expected to provide important inputs for the Company's targeted Q4 2026 Scoping Study.
