GTI Energy is advancing one of the few near-term, low-cost In-Situ Recovery (ISR) uranium projects in the U.S. GTI is positioned to deliver value from America's nuclear revival, with its flagship Lo Herma Project at the forefront of the domestic supply chain rebuild.
Highlights
● Drilling permit approved by BLM; final Wyoming state approval expected August 2025
● Top-tier Wyoming drilling services providers contracted with mobilisation due September 2025
● Drilling aimed at growing Mineral Resource Estimate (MRE) and upgrading Inferred resources
● Targeting Mineral Resource Estimate increase and upgrade in Q4 2025
● Lo Herma Project is strategically located to capitalise on the U.S administration's strong support for domestic uranium supply growth
● Additional drill-permitted projects in Wyoming's Great Divide Basin and Green Mountain area, as well as brownfield conventional uranium/vanadium assets in Utah's Henry Mountains provide exploration upside
GTI Energy Limited (ASX:GTR) (GTI or the Company) is extremely pleased to advise that it has received Bureau of Land Management (BLM) approval and contracted its preferred Wyoming based exploration drilling contractors, Single Water Services LLC (Single Drilling) and Hawkins CBM Logging Inc. (Hawkins Logging) for its 2025 drill program at Lo Herma. This has allowed the Company to lock in both contract rates and a drilling schedule in what appears to be a busy 2025 drilling season in the uranium sector across Wyoming.
GTI Executive Director Bruce Lane commented
"With the uranium sector regaining strong institutional and government backing in the U.S, the Lo Herma Project is ideally positioned to help fill that critical supply gap.
"Having now received BLM approval, and with the support from the government level, our final step is sign-off from the State of Wyoming for our drilling plan. This is expected to be completed in time for drilling to commence during September.
"This drilling is targeted to grow the resource by upgrading the current Exploration Target areas to the north of proposed Mine units 1 and 2, in addition to increasing the proportion of Indicated resources at the project with an aim to deliver an updated Mineral Resource Estimate by end of calendar year 2025. The resource update will be followed by a revised Scoping Study to outline the project economics as we move towards a Final Investment Decision (FID) for mine construction".
Drill Program Overview
As announced to market1 , the planned 2025 drilling program at Lo Herma includes a permit application for up to 121 drill hole locations with up to 37,500 metres (approximately 123,000 feet) of drilling.
The BLM has now approved GTI's amended drilling permit, which was lodged as advised on July 10, 2025. The State of Wyoming's Land Quality Division (LQD) is progressing with their review of the permit amendments. Pending LQD approval and bonding, which is expected in August, GTI plans to mobilise drill rigs and commence drilling at Lo Herma during September 2025.
GTI has renewed contracts with Single Drilling and Hawkins Logging to provide drilling and geophysical logging services for the upcoming exploration program. Both companies are top-tier, Wyoming based contractors with established records of delivering professional, efficient, and timely operations. With several years of successful collaboration with GTI, these trusted service providers are positioned to deliver yet another season of operational excellence and high-quality results.
The drilling program is designed to achieve multiple objectives critical to advancing the Lo Herma Project. The primary goals include step-out drilling to target resource expansion to the north of both proposed Mine Units 1 and 2, (Figure 1 and Figure 2) where there is potential to increase the Project's overall resource base. Additionally, infill drilling is planned to upgrade current Inferred Mineral Resources to Indicated or Measured category within Mine Units 1 and 2, thereby increasing resource confidence.
Drill Program Overview Continued
The program also includes provision for the installation of additional groundwater observation wells to support subsequent further hydrogeologic testing, which is essential for understanding groundwater dynamics and ensuring environmentally responsible operations. Diamond drilling is planned to collect further mineralized core samples for additional metallurgical testing, aimed at optimising mineral processing and recovery techniques.
The drilling campaign is expected to progress efficiently, with all major objectives projected to be completed by the end of 2025. The successful execution of this field program is expected to provide critical data to support updating and optimising the resource models and further define key operational parameters.
These outcomes will play a pivotal role in advancing the Lo Herma project towards production and is expected to allow the Company to update the current Mineral Resource Estimate (Table 1) and Scoping Study to demonstrate the economic potential of the project.
Exploration Upside
GTI also holds high-potential, drill-permitted projects in Wyoming's Great Divide Basin and Green Mountain area, as well as brownfield conventional uranium/vanadium assets in Utah's Henry Mountains.
About us:
Focused on exploring for, defining and developing economic ISR Uranium resources – GTI Energy is part of Wyoming's Insitu Recovery (ISR) uranium mining revival.
GTI saw the US uranium supply collapse and anticipated the coming surge in demand for domestically produce uranium as a key part of America's drive for homegrown, sustainable clean energy solutions. This led us to position GTI to be part of the resurgence in demand for uranium using the lowest-cost and cleanest method of mining uranium, ISR.
Providing corporate transparency, GTI has also adopted an internationally recognised Environmental, Social and Governance SCM Framework where progress is measured against these core metrics and included in GTI's annual report on the ASX.
The key driver of value creation for GTI is making economic uranium discoveries. GTI's ISR uranium projects in Wyoming position us to define uranium resources that can potentially be developed quickly & cost effectively with a low environmental impact.
