Highlights

  • GTI Energy expanded Lo Herma's JORC uranium resource to over 7.37 million pounds of U3O8 in Wyoming.
  • ISR extraction avoids tailings dams, massive excavation, and delivers lowest-quartile operating cost profiles.
  • Lo Herma is within 50 miles of commercial ISR satellite facilities operated by Cameco and Energy Fuels.
  • A preliminary economic scoping study is advancing alongside groundwater pump testing and leach amenability trials.

As US bipartisan legislation moves to ban Russian nuclear fuel imports and domestic uranium supply tightens, GTI Energy (ASX:GTR) is sitting in Wyoming's Powder River Basin with a growing 7.37-million-pound uranium resource at Lo Herma — extractable via low-cost, low-footprint in-situ recovery methods from sandstone aquifers that roll-front uranium has been accumulating in for millions of years.

Lo Herma ISR Resource Expands to 7.37Mlb

Comprehensive mud-rotary drilling campaigns at the flagship Lo Herma In-Situ Recovery Uranium Project successfully validated thick roll-front uranium intercepts across multiple sandstone aquifers, expanding the JORC-compliant Mineral Resource Estimate to more than 7.37 million pounds of triuranium octoxide. Lo Herma is located within the prolific Powder River Basin, Wyoming's undisputed heartland of uranium mining with established regulatory frameworks and dedicated state agreement protocols.

ISR extraction circulates oxygenated groundwater solutions through permeable ore-bearing sandstone formations, avoiding massive open-cut excavation, eliminating environmental tailings dams, compressing surface ecological disturbance, and delivering lowest-quartile operating costs. This process significantly de-risks both the environmental approval pathway and the operational cost profile relative to conventional hard-rock uranium mining.

Strategic Position Within Wyoming's Nuclear Infrastructure

Lo Herma is situated within a 50-mile trucking radius of several commercial ISR satellite facilities operated by Cameco and Energy Fuels. This proximity enables GTI to pursue capital-light toll-milling arrangements, avoiding the requirement to construct a standalone central processing plant — a material capital saving for a micro-cap developer.

Wyoming offers well-established regulatory frameworks for uranium ISR, with multiple licensed processing plants carrying idle capacity. This mature regulatory and infrastructure environment materially reduces the technical development risk for Lo Herma relative to uranium projects in less established jurisdictions.

Scoping Study and US Nuclear Demand Drivers

GTI's immediate operational focus centres on completing a preliminary economic scoping study defining initial production rates, capital expenditure estimates, mine life projections, and unit all-in sustaining operating costs. Baseline environmental groundwater monitoring, pump testing to determine aquifer confinement, and metallurgical leach recovery amenability trials are advancing in parallel.

Uranium fundamentals remain constructive as global utilities confront structural supply deficits driven by nuclear power expansion, reactor life extensions, and US federal mandates aimed at banning Russian nuclear fuel imports. GTR shares closed flat at $0.130 on 2 October 2026 with a market capitalisation of $12.54 million, reflecting a modest 7.14% decline over 12 months.

Regulatory and Financial Risks

Securing state and federal aquifer exemptions, source material licences, and environmental quality permits from the Wyoming Department of Environmental Quality involves multi-year regulatory review processes — the primary timeline risk for Lo Herma's development schedule.

As an evaluation company without operating cash flow, GTI relies on equity markets or commercial joint ventures to finance technical studies. Project economics remain highly sensitive to global spot and term uranium contract pricing, foreign currency exchange fluctuations, and inflationary pressures on specialised mud-rotary drilling and hydrologic casing equipment.
