Drilling Success Expands Mineralised Trends at Lo Herma

GTI Energy Limited (ASX: GTR) (GTI or Company) is pleased to advise that a total of 66 mud rotary drill holes have now been completed at its 100% owned Lo Herma ISR Uranium Project (Lo Herma), located in Wyoming’s prolific Powder River Basin (Figures 1 & 2). GTI has now completed 13,405m (43,980 ft) of drilling at Lo Herma this summer representing ~87% of the planned 76-hole program.


HIGHLIGHTS

  • GTI has now completed 66 resource estimate development drill holes of 76 planned at the Lo Herma ISR uranium project during the 2024 drill program
  • Drilling to date confirms that uranium mineralisation continues north from the current mineral resource area with strong mineralised intercepts over good thicknesses encountered stretching at least 2km north along projected trends
  • Best mineralised intercepts reported include 6.0ft at 0.123% (1,230ppm) eU308 in drill hole LH-24-028, and 11.0 ft at 0.054% (540ppm) eU308 in drill hole LH-24-063

This news release follows on from the Company’s 31 July 2024 news release which reported results from the first ten (10) drill holes of the 2024 drill program. The results from the next fifty- six (56) drill holes (Table 2) include several highlights:

  • Drill hole LH-24-028 returned the highest-grade intercept at 6.0ft of 0.123% eU3O8, and a total hole grade thickness (GT) of 0.903*.
  • 45 of 56 drill holes have intercepted on trend mineralisation.
  • Mineralisation continues across multiple sandstone units as GTI expands the mineralised trends to the north, as demonstrated by drill hole LH-24-03 which encountered 11ft of 0.054% eU3O8 (0.594 GT) and 6.5ft of 0.043% eU3O8 (0.280 GT) from different sand units.

* Typical economically viable ISR grade and GT cut-offs are: 0.02% (200ppm) U3O8and 0.2GT i.e., 10 ft (3 m) @ .02% (200ppm) U3O8.

GTI Executive Director & CEO Bruce Lane commented “Drilling to date at Lo Herma has been very successful in demonstrating extensions of mineralisation, with strong GT numbers to the north of the project area and at depth in the sands of the lower Wasatch formation. Results so far give us great confidence that we can grow the global uranium resource estimate and upgrade a material portion to the indicated category. Drilling is currently running to schedule with operations now moved to the east of the project area to test for deeper mineralisation in the Fort Union formation. The sand units of the lower Wasatch formations are showing reliable continuity and mineralisation far along trend to the north so we are now excited to see what the deeper Fort Union formation sands may hold as we move to our final exploration area for this phase of drilling.”

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 producing Willow Creek (Irigaray & Christensen Ranch) & idled Reno Creek ISR plants, Cameco’s idled Smith Ranch-Highland ISR facilities and Energy Fuels idled Nichols Ranch ISR plant (Figure 1).

The Powder River Basin has extensive ISR uranium production history with numerous defined ISR uranium resources, central processing plants (CPP) & satellite deposits (Figure 1). 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 Lo Herma 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. A total of 1,391 original drill hole logs were digitised for gamma count per second (CPS) data and converted to eU3O8% grades.

833 of these historical drill holes are located on GTI’s land position and were used to prepare the maiden MRE. 21 additional drill holes are located in an expanded area of additional claims that were subsequently staked across Section 4 of Township 36N, Range 75W. Along with the 26 drill holes completed in the initial 2023 drill program, GTI holds data from 880 drill holes within the current Lo Herma mineral holdings prior to the current 76 hole drill campaign.

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 (refer to Table 1).

Whilst additional redox trends were interpolated based on the 2023 drilling and acquisition of the newly located mineral claims, the Exploration Target has not yet been updated. GTI plans to update the mineral resource and exploration target estimates following completion of the current 2024 drilling campaign.

Sweden Moves to Lift Uranium Mining Ban Through Legislative Proposal

Sweden has announced plans to lift its seven-year ban on uranium mining, with a proposal to amend the Environmental Code and Minerals Act expected in parliament later this year. If approved, the changes would take effect on January 1, 2026.

The proposal follows the conclusions of a government inquiry completed in December 2024, which recommended that uranium be treated under the same legal framework as other concession minerals.

That recommendation was reviewed by the Council on Legislation in June 2025, clearing the way for parliament to consider a repeal.

Basin Energy Shifts Focus to Uranium Assets with District-scale Potential in Queensland

Basin Energy’s (ASX:BSN) recent acquisition of a significant landholding in the Mount Isa region of Northwest Queensland has propelled the company into Australia's uranium and rare earths exploration landscape, giving investors exposure to a cost-effective, district-scale opportunity, according to the company’s managing director, Pete Moorhouse.

“The Queensland opportunity provides direct exposure for district-scale wins from first-pass drilling with reverse circulation and aircore, so this is relatively cheap drilling on district-scale opportunities. Northwest Queensland, from the jurisdiction (perspective), is a real prime opportunity for critical minerals,” said Moorhouse.

The Basin Energy executive also noted that there are significant government initiatives in place at both the federal and state level to support the region’s growth, as well as recent M&A activity in the uranium space.

Cameco, Kazatomprom Production Cuts Stoke Uranium Market Tightness

Shares of Cameco (TSX:CCO,NYSE:CCJ) were on the rise after the uranium major announced it is reducing its annual production guidance due to expansion delays at the McArthur mine in Saskatchewan, Canada.

Instead of the projected 18 million pounds of U3O8 the company was aiming for from its McArthur River joint venture with Orano, the revised output tally reduces 2025’s production total to between 14 million and 15 million pounds.

In January, Cameco warned that delays at McArthur River — including slower-than-expected ground freezing, development setbacks and labor constraints — could affect its 2025 production outlook.
