GTI Energy (ASX:GTR) outlines ISR uranium development plan at Lo Herma in the Powder River Basin
Scoping Study supports both central processing and satellite plant concepts
Expansion studies and testing underway to support long-term uranium output
GTI Energy (ASX:GTR), a player in the uranium mining sector, reported outcomes from its recently completed Scoping Study on the Lo Herma Uranium Project, located in Wyoming’s Southern Powder River Basin. This region has long been regarded as a key area for uranium production using the in-situ recovery (ISR) process. With its presence on the ASX 200, GTR aligns its project plans with ongoing global developments in nuclear energy infrastructure and base load power expansion.
The company’s Scoping Study was conducted by engineering firm BRS Engineering. It examined development pathways including a central processing plant (CPP) configuration and an alternate satellite model. Both configurations were found to be economically feasible under existing uranium benchmarks and market indicators.
Scoping Study Supports ISR Development
The preferred case involves a CPP model to process uranium from Lo Herma, while an alternative satellite model would rely on nearby processing infrastructure. GTI Energy noted that both options would use ISR techniques known for their cost-efficiency and minimal surface disruption.
The initial study estimates a mine life of several years and outlines a planned annual production capacity for triuranium octoxide. Infrastructure development is expected to support long-term extraction and processing needs, and both development paths show similar economic outputs based on uranium price forecasts.
The study also mentions a relatively short payback timeframe after production begins, with low initial capital expenditure estimates. The project's economic strength is underpinned by its location, simple metallurgy, and proximity to critical infrastructure such as power, water, and transportation.
Strategic Site and Regional Benefits
Lo Herma’s location in Wyoming's Southern Powder River Basin offers key advantages for ISR uranium development. The basin features a history of successful ISR operations and remains one of the most established uranium-producing zones in the United States. GTR reports that Lo Herma is comparable to other projects in the region and benefits from established regulatory and infrastructure support for uranium mining.
The site includes a producing ISR facility and an additional satellite plant under construction. This setup enables flexible scaling depending on technical outcomes and future demand conditions. Lo Herma joins other uranium projects in the basin that have contributed to Wyoming’s energy resources for several decades.
Continued Work on Exploration and Feasibility
GTI Energy is conducting further exploration drilling aimed at converting existing exploration targets into mineral resources. These efforts are expected to support a longer mine life and stronger production continuity. The exploration targets are defined by uranium grade and tonnage ranges, aligned with historical data for ISR operations in the region.
Groundwater pumping trials and metallurgical testing will further refine hydrological and chemical parameters for ISR efficiency. Additional assessments are also planned for water supply, energy logistics, and equipment sourcing. Environmental planning and amenity studies are expected to form part of a proposed Feasibility Study.
Commissioning and construction are currently scheduled for a future date, with a start of production to follow. GTI continues to evaluate all project elements to support its uranium development strategy at Lo Herma in coordination with broader market and regulatory frameworks.
