GTI Energy Ltd (ASX: GTR) (GTI or Company) is pleased to provide an update on its planned airborne geophysics program and progress towards reporting an Inferred Mineral Resource Estimate (MRE), in accordance with the JORC code 2012, at its 100% owned ~12,000-acre Lo Herma ISR Uranium Project in Wyoming’s Powder River Basin uranium district (Lo Herma) (Figure 2).
Highlights:
- Airborne geophysics survey has commenced at Lo Herma with aircraft expected to move to Green Mountain & Loki West in due course
- The geophysical survey is designed to advance & prioritise exploration targets
- Additional historical data secured for Lo Herma to enhance exploration potential
- All 1,445 historical drill logs now digitised & compiled in the Lo Herma resource model
- Lo Herma maiden mineral resource estimate report due 1st week of July
- Lo Herma initial drill targeting completed with permitting ongoing for verification & exploration drilling campaign during late 2023 or 1st half 2024
AIRBORNE SURVEY
The airborne geophysical survey has now commenced after delays caused by weather, aircraft repairs and FAA approval. The survey has commenced at the Company’s Lo Herma project area and will, in due course, move to the Loki West and Green Mountain project areas (Figure 2). Terraquest Ltd are conducting the survey using a Piper-Navajo twin engine aircraft (Figure 1) loaded with a suite of sensors that provide detailed radiometric, magnetic and electromagnetic data, allowing for correlation between the three products to further refine the Company’s high- priority targets and potentially locate new targets for upcoming drill programs. The survey sensing package includes a Resolution Magnetometer, Horizontal Gradiometer, Max Gamma Radiometer and Matrix VLF-EM sensors.
Uranium mineralisation at Lo Herma, Green Mountain and Loki West is sandstone hosted. The airborne geophysics is expected to help define major sandstone channel systems which, coupled with historical drilling data and radiometric anomalies, will aid in refining drill target definition.
Executive Director Bruce Lane commented “this airborne geophysical survey is an important component of our program to advance our 100% owned Lo Herma, Loki West & Green Mountain Uranium Projects. The airborne survey follows the results of our recent historical drilling analysis and ground reconnaissance programs that have highlighted high-quality exploration targets at all three project areas. This survey is also expected to help further refine & confirm drill targets ahead of planned drilling at Lo Herma during late 2023 or the first half of 2024.”

LO HERMA PROJECT – ADDITIONAL HISTORICAL DATA
The Company has secured additional historical data, relating to Lo Herma, containing scanned original drill hole maps, internal memos, drill hole logs with assay data, and interpretive geological cross sections and trend maps produced by Pioneer Nuclear Inc. (Pioneer) and partners, responsible for exploration work at the Lo Herma project site during the 1970’s & 80’s.
Of particular interest is an interpretive geological roll-front trend map collection, which represents redox trend projections and roll front mapping. These maps are of the same series that were included with the original Lo Herma data package and fill a gap in the original data package. This data will allow for a more comprehensive understanding of the geological interpretations of almost a decade of exploration activity. This is expected to aid in the development of additional exploration targets in the lesser explored sand units across the project.
A preliminary breakdown of the data package contents follows:
- 22 Geologic interpretive trend maps
- 29 Detailed drill hole collar maps including mineral intercept summaries
- 38 Geologic cross sections with gamma logs in section
- 12 Claims maps with limited accompanying information
- 9 reports and memos
- 7 Core hole drill logs with assay data, physical properties, & petrological descriptions
The data has been scanned and combined into the Lo Herma database for interpretation and inclusion in the impending JORC 2012 resource report for the project.
Work is continuing on permitting for the planned drill program. Interpreted results of the airborne geophysical survey will also be integrated into the geological & resource model for the deposit when the results come to hand in the coming weeks.

Investor Insight
GTI Energy presents an intriguing opportunity for investors seeking exposure to the uranium sector, given its focus on ISR projects in the US aligning well with macro trends in the nuclear energy industry and geopolitical shifts favouring domestic uranium production.
Overview
GTI Energy (ASX:GTR,OTCQB:GTRIF) is an Australia-based uranium exploration and development company focused on uranium projects in Wyoming, USA, that are amenable for in-situ recovery (ISR). In uranium mining, ISR is the lowest cost and least environmentally damaging form of uranium recovery, especially when alkaline leach and ion exchange processes are utilised.
The company’s flagship Lo Herma project in the Powder River Basin is a sandstone-hosted roll front uranium deposit, which contains a recently updated mineral resource of 8.57 million pounds (Mlbs) of U₃O₈ at an average grade of 630 parts per million (JORC 2012 compliant), with a substantial additional exploration target in the range of 6 to 11 Mlbs – GTI recently completed an interim Scoping Study on this project. GTI also holds projects in the Great Divide Basin (inferred resource of 1.66 Mlbs) and Green Mountain areas of Wyoming, as well as earlier-stage conventional uranium/vanadium assets in Utah. As of the latest update, GTI has delineated total combined uranium resources of 10.23 Mlbs (indicated and inferred) and combined exploration targets ranging from 12.14 to 15.21 million tonnes across its Wyoming projects.
Wyoming’s ISR uranium processing assets and GTI project locations
GTI is positioning itself to take advantage of the worsening uranium supply deficit and rapidly growing demand for uranium, particularly from the United States. The US remains the world’s largest consumer of uranium but imports over 95 percent of its supply. GTI’s strategy centres on developing low-cost ISR uranium projects in Wyoming – historically one of the most productive uranium regions in the US – with established infrastructure, regulatory support, and proximity to existing ISR processing facilities.
The uranium market is experiencing a serious supply deficit and a significant resurgence in demand driven by several factors:
- Supply constraints following decades of underinvestment and an overreliance on Russian and Kazakh supply chains;
- Rapid growth in global electricity demand and recognition of nuclear energy as a clean baseload source aligned with decarbonization targets;
- Geopolitical realignment leading to a bifurcated uranium market, with the US banning imports of Russian nuclear fuel as of August 2024, intensifying the urgency for domestic supply security;
- Accelerating momentum for SMRs (Small Modular Reactors), nuclear restarts, and new gigawatt-scale builds in the US and abroad.
In the United States specifically, there is bipartisan policy support for revitalising the domestic uranium industry. Key initiatives include the formation of a strategic uranium reserve, over US$6 billion in grants for existing nuclear facilities, and tax incentives for new builds under the Inflation Reduction Act. Additionally, the US Department of Energy has called for tripling US nuclear capacity to 300 gigawatts by 2050. Demand signals are also coming from private sector growth, particularly AI-driven data centre development and long-term net-zero pledges by institutional investors and banks.
GTI Energy’s project strategy
In the longer term, GTI recognises the value potential of consolidation within the fragmented US uranium sector. The company remains open to strategic partnerships, joint ventures or merger and acquisition opportunities that could accelerate its development timeline, enhance scale, and unlock synergies. Such initiatives could ultimately strengthen GTI’s path to production and improve its overall value proposition to shareholders.
Company Highlights
- GTI Energy is focused on ISR-amenable uranium projects in Wyoming, USA.

- GTI also holds drill permitted projects with defined resources and exploration targets in the Great Divide Basin and Green Mountain areas in Wyoming, and uranium-vanadium assets with significant recent exploration data in Utah.
- To date, GTI has delineated total combined uranium resources of 10.23 Mlbs (indicated and inferred) and substantial combined exploration targets in the range 12 to 20 Mlbs across its Wyoming projects.
- Wyoming is a historically significant uranium producing region with existing infrastructure and a supportive regulatory environment.
- GTI is well-placed to take advantage of the worsening uranium supply deficit and rapidly growing demand for uranium, particularly from the United States, the world’s largest consumer of uranium.
Key Projects
Wyoming Uranium Projects
GTI's focus on Wyoming ISR projects positions it well to capitalize on trends in the uranium sector. ISR mining is generally faster to build, lower cost, and more environmentally friendly than conventional mining methods. Wyoming has a long history of uranium production and hosts current producers and several additional permitted processing facilities, potentially allowing for rapid development of new projects.
The Wyoming projects – comprising the Lo Herma, Great Divide Basin, and Green Mountain projects – are located in the Powder River and Great Divide Basins.
JORC Resources and Exploration Targets
Lo Herma
The company’s exploration work is currently centered on advancing its 100 percent owned flagship Lo Herma project, where drilling in 2023 and 2024 successfully verified and expanded the historical drill hole database. As of December 2024, the project hosts a JORC-compliant mineral resource estimate of 8.57 Mlbs of U₃O₈ at an average grade of 630 ppm, comprising 2.78 Mlbs indicated and 5.79 Mlbs inferred.
The Lo Herma project is located just 10 miles from Cameco's Smith Ranch-Highland facility – the largest ISR uranium plant in the United States – and is ideally situated for potential future production synergies. In addition to the current resource, the company has defined an exploration target of 6 to 11 Mlbs, with over 950 drill holes completed across the project area.
GTI completed hydrogeologic field testing and metallurgical leach studies during the March 2025 quarter. Results demonstrated that Lo Herma mineralisation is amenable to alkaline ISR recovery with uranium recoveries averaging 75 percent, consistent with other ISR operations in the district.
Following the successful completion of these studies, GTI delivered an interim scoping study in Q2 2025, managed by BRS Engineering. The study confirmed the project’s potential viability and outlined attractive baseline economics for both central processing and satellite mining development options. The company is now finalising plans for a follow-up drilling campaign in H2 2025. This next phase will include infill and step-out drilling to increase overall mineral resources and upgrade resource classification, while collecting further hydrogeological and metallurgical data.
Great Divide Basin and Green Mountain
The company continues to progress its additional Wyoming projects, including the Great Divide Basin and Green Mountain areas. Drilling is permitted for 2025, positioning GTI to unlock further value across these strategic tenements.
The Great Divide Basin project includes the Thor, Logray, Loki, Odin, Teebo and Wicket claims. It holds a JORC inferred mineral resource of 1.66 Mlbs of U₃O₈ at 570 ppm, and a defined exploration target of 6.55 to 8.11 million tonnes grading 420 to 530 ppm. The area benefits from significant historical exploration data and proximity to major uranium infrastructure, including Ur-Energy’s Lost Creek plant and Rio Tinto’s Sweetwater Mill.
GTI’s footprint in this region was expanded by acquiring the Green Mountain project, which includes 5,585 hectares of contiguous claims directly adjoining Rio Tinto’s tenements. Historical drilling and geophysical surveys confirm the presence of uranium mineralisation in sandstone-hosted roll fronts within the Battle Springs formation.
Green Mountain lies adjacent to notable regional projects including Energy Fuels’ Sheep Mountain (30 Mlbs), Ur-Energy’s Lost Soldier, and UEC’s Antelope deposits, positioning GTI near major development and production infrastructure in the basin.
Utah
Henry Mountains Uranium Project
GTI’s Henry Mountains project in Utah is a brownfields uranium-vanadium opportunity located within the prolific Colorado Plateau uranium province. Exploration has focused on a 5 km mineralised trend between the Rat Nest and Jeffrey claim groups, including the Section 36 state lease.
Uranium and vanadium mineralisation in this area is shallow – typically 20 to 30 metres deep – and has historically supported significant production. Since 1904, the district has yielded more than 92 Mlbs of U₃O₈ and 482 Mlbs of V₂O₅ from sandstone-hosted ores. The project remains a strategic asset with future development or transactional optionality as GTI advances its Wyoming portfolio.

Disrupting the uranium supply chain through highly prospective ISR projects in Wyoming
North Shore Uranium: Unlocking Value Across Two World-class Uranium Districts in North America
North Shore Uranium (TSXV:NSU) is a uranium exploration company focused on North America, advancing a dual-track strategy aimed at high-impact discoveries in two of the world’s most prolific uranium regions: the eastern Athabasca Basin in Saskatchewan, Canada, and the Grants Uranium District in New Mexico, USA. With a lean capital structure, fully permitted drill targets in Saskatchewan, and strong insider ownership, the company is well-positioned to create value through cost-effective exploration and resource definition in a rising uranium price environment.
The Rio Puerco project, located in New Mexico’s Grants District—a historically productive uranium belt responsible for over 340 million pounds of past U₃O₈ production—offers strong potential. Drawing on data from approximately 800 historical drill holes, a JORC-compliant inferred resource estimate of 11.4 million pounds U₃O₈ was completed in 2009. Early assessments suggest potential for in-situ recovery (ISR) mining, one of the lowest-cost extraction methods in the industry.
North-Shore-Uranium-Athabasca-Basin-ProjectsAt the Falcon project in the Athabasca Basin, North Shore’s maiden 2024 drill program confirmed near-surface uranium mineralization in previously untested zones, underscoring the project’s discovery potential. The company has outlined a 7-kilometre conductive corridor with high-priority drill targets in the South Priority Area and is planning prospecting and follow-up drill programs.
Company Highlights
- Dual Jurisdiction Exposure: Active exploration in Athabasca Basin and the Grants Uranium District, two of the most historically significant uranium-producing regions in North America.
- Rio Puerco Option: Binding term sheet signed for a transaction that would see North Shore Uranium acquire up to an 87.5 percent of the Rio Puerco uranium project in New Mexico, where there is a historical resource estimate of 6 million tonnes grading 0.09 percent eU₃O₈ for 11.4 million lbs of U₃O₈.1
- Falcon Discovery in 2024: Maiden drill program confirmed near-surface uranium mineralization at two targets on the Falcon property in the Athabasca Basin in a previously undrilled area within 30 km of the active Key Lake uranium mill.
- Path to Resource Definition: Upon completion of the transaction, North Shore plans to validate historical data, attempt to expand the resource and evaluate the ISR potential at Rio Puerco and concurrently work to expand the discovery footprint at Falcon.
- Lean Structure, Strong Insider Support: $2.2 million market cap (as of July 2025), 40.3 million shares outstanding, with 43.3 percent held by insiders and founding investors.
- High-caliber Team: Led by award-winning geologist Brooke Clements and supported by proven uranium dealmakers and technical experts.
