Drilling Commences at Lo Herma ISR Uranium Project in Wyoming

GTI Energy Ltd (ASX: GTR) (GTI or Company) advises that drilling has now commenced at its 100% owned Lo Herma ISR Uranium Project (Lo Herma) located in Wyoming’s prolific Powder River Basin (Figures 1 & 2). The drill program is utilising mud rotary drilling & down hole gamma logging.


  • Mud rotary drilling has started at GTI’s Lo Herma ISR uranium deposit.
  • Initial drilling of up to 26 holes (~15,000ft/~4,600m) to validate and upgrade the maiden JORC inferred resource of 5.7Mlbs U3O8 at average grade 630ppm
  • Drilling to also target exploration potential along trend in the Wasatch Formation & in the deeper Fort Union Formation which Cameco produces from ~10 miles west.
  • Lo Herma is ~10miles from the US’s largest ISR U3O8 production plant at Cameco’s Smith Ranch-Hyland & ~60 miles from UEC’s Irigaray & Energy Fuels’ Nichols Ranch

LO HERMA URANIUM PROJECT – LOCATION & BACKGROUND

 

The Lo Herma ISR Uranium Project (Lo Herma) is located in Converse County, Powder River Basin (PRB), Wyoming (WY). The Project lies approximately 15 miles north of the town of Glenrock and close to seven (7) permitted ISR uranium production facilities. These facilities include UEC’s Willow Creek (Irigaray & Christensen Ranch) & Reno Creek ISR plants, Cameco’s Smith Ranch-Highland ISR facilities and Energy Fuels Nichols Ranch ISR plant (Figure 2). The Powder River Basin has extensive ISR uranium production history with numerous defined ISR uranium resources, central processing plants (CPP) & satellite deposits (Figure 2). The Powder River Basin has been the backbone of Wyoming U3O8 production since the 1970s.

As reported to ASX on 14 March 2023, a comprehensive historical data package, with an estimated replacement value of ~$15m, was purchased for the Lo Herma project in March of 2023. The data package includes original drill data for roughly 1,771 drill holes, from the 1970’s and 1980’s, pertaining to the Lo Herma region. 1,391 original drill hole logs were digitised for gamma count per second (CPS) data and converted to eU3O8% grades. 845 of the drill holes were located on GTI’s current land position & used to prepare the Mineral Resource Estimate.

An initial exploration target for the Lo Herma project was previously announced to the ASX on 4 April 2023. An additional data package containing previously unavailable drill maps with geologically interpreted redox trends was subsequently secured by GTI as announced to the ASX on 27 June 2023. The additional redox trend interpretations allowed for an update of the previously reported Lo Herma exploration target (Table 1).

TABLE 1: SUMMARY OF INFERRED MRE & EXPLORATION TARGETS (ASX 5 JULY 2023)The potential quantity and grade of the Exploration Targets is conceptual in nature and there has been insufficient exploration to estimate a JORC-compliant Mineral Resource Estimate. It is uncertain if further exploration will result in the estimation of a Mineral Resource in the defined exploration target areas.

DRILLING PLAN

The initial drilling program is a 26-hole (~15,000ft/~4,600m) campaign to both confirm a subset of historical drill holes as well as explore untested locations and depths. Drilling is expected to average 500 feet with a maximum potential depth of 1,500 feet.

Several of the drill holes are sited to target locations for confirmation of the historical drilling data. If conditions allow, the drillers will attempt to recover rock core samples of the mineralized zone for metallurgical testing. In addition to the confirmatory drilling, drill holes have been planned to test the alteration conditions of the host sand units across the property and geologic strata. This will help in further refining the locations of the projected REDOX trends and in improving targets for future exploration. These stratigraphic holes will also bring the benefit of testing the deeper sand units of the Fort Union formation which were historically underexplored.

This initial program is part of a larger permitted campaign totalling 68 holes with the balance of the campaign to be refined & assessed for execution during 2024 subject to results.

Terra Clean Energy Ramps Up Summer Drilling Plans, Eyes Resource Update

Terra Clean Energy (CSE:TCEC,OTCQB:TCEFF,FWB:C9O0) President and CEO Greg Cameron outlines the company's upcoming summer drill program at the South Falcon East uranium project, building on strong results from a winter campaign at the Fraser Lakes B deposit.

“The plan is to get up to 2,500 meters back into this new area of interest. Hopefully drill into what we're defining as an unconformity basement-hosted uranium deposit with significantly higher grade than we currently have,” he said.

“We would have the ability to update that resource report in some fashion, maybe early 2026 or mid-2026, so those are the two key catalysts. But it's all about drilling and adding pounds to the current resource and, more importantly, significantly enhancing that grade which we think we have," Cameron added.

Top 3 ASX Uranium Stocks of 2025

Uranium broke out in 2024, with the spot price rising to a 17 year high of US$106 per pound early in the year. Despite a pullback to about US$78, uranium is still more than 40 percent higher than it was two years ago.

Although the market is dealing with ample supply and uncertain demand in 2025, experts are predicting a bright future as countries around the world pursue energy security goals.

Against that backdrop, ASX-listed uranium companies have been making moves in 2025.

15 Uranium Companies Exploring Canada's Athabasca Basin

Uranium market watchers know that Canada’s Athabasca Basin is among the world’s richest uranium jurisdictions and hosts several of the highest-grade uranium deposits on the planet.

Spanning close to 100,000 square kilometers of the Canadian Shield of Northern Saskatchewan and Alberta, the Athabasca Basin is a major contributor to Canada’s status as the second largest uranium producer and the third largest country by uranium reserves.

Unsurprisingly, the region is home to the world’s largest uranium mine, Cigar Lake. The mine reports average grades of 14.69 percent U3O8 and accounts for 14 percent of global uranium production.
