Strong ISR mining potential confirmed by drilling and hydro tests

GTI Energy (ASX:GTR) has reported significant operational progress during the March 2025 quarter at its Lo Herma in-situ recovery (ISR) uranium project in Wyoming, moving closer to a comprehensive scoping study due in Q2 2025.

The company achieved uranium recoveries of up to 80% from agitation leach testing, which simulated ISR conditions using alkaline solutions. These outcomes align with established ISR benchmarks in the Powder River Basin, reaffirming the project’s technical potential. Average uranium concentrations reached 45 milligrams per litre, with peak values hitting 200 milligrams per litre, indicating robust leaching performance.

Groundwater monitoring wells showed that mineralisation lies well within the saturated aquifer—an essential requirement for ISR extraction. Minor leaching of elements such as calcium and selenium remained within acceptable industry standards.

Drilling during the quarter totalled 810 metres across four groundwater monitoring wells. All mineralised intercepts exceeded the 200 ppm eU3O8 threshold, with standout results including 10 feet at 0.046% and 5 feet at 0.049% eU3O8. These drilling efforts not only confirmed existing data but also provided fresh core for hydraulic and permeability testing.

Hydrological assessments revealed that uranium-bearing zones are positioned well below the water table, with vertical separations up to 1,178 feet. Permeability testing returned an average hydraulic conductivity of 5.54 × 10⁻⁷ m/s—within optimal ranges for ISR-compatible sandstone formations.

All essential fieldwork for the Lo Herma scoping study was completed by quarter-end, including testing for groundwater dynamics and metallurgical recovery. Preliminary designs and cost modelling for ISR wellfields and processing infrastructure are also now finalised. The study, led by BRS Engineering, remains on track for a Q2 release, providing a clearer roadmap for the project’s development phase.

GTI Energy holds a 100% interest in the Lo Herma Project, which hosts an estimated 8.57 million pounds of contained uranium oxide. Total mineral resources across GTI's Wyoming portfolio now exceed 10.23 million pounds. Additional exploration assets are held in the Great Divide Basin, Green Mountain region, and Utah’s uranium-vanadium fields.

From a corporate standpoint, the company reported exploration spending of A$372,000 during the quarter, ending March with A$913,000 in cash and a further A$255,000 in standby equity capital.

With the Lo Herma project advancing steadily and the uranium market attracting growing attention, GTI Energy (ASX:GTR) continues to position itself within Australia’s evolving energy sector. As investor interest in ASX dividend stocks rises and the broader ASX200 index tracks clean energy momentum, GTI's developments could place it on the radar of resource-focused investors.

The company’s Annual General Meeting is scheduled for May 8, 2025, with key performance rights linked to progress milestones including drilling and resource upgrades.
