Lo Herma ISR Uranium Project, Resource Drilling Funded

Following the recently completed placement to sophisticated and institutional shareholders, GTI Energy Ltd (GTI or Company) is pleased to provide an update on the upcoming resource expansion drilling program at the Lo Herma ISR uranium project in Wyoming’s Powder River Basin (PRB). In advance of further news related to progress of the planned drill program at Lo Herma, the following provides a summary of the resource expansion potential and objectives of the 2024 Phase II drilling.

HIGHLIGHTS

• Upcoming Q3 resource drilling is fully funded
• Drilling will target expansion and upgrade of the current Inferred Mineral Resource Estimate of 5.71 Mlbs U3O8 at average 630ppm
• Drilling to commence in the coming weeks – starting late July or early August
• Planned rights entitlement offer to all shareholders on the same terms as the recent placement – details to be provided in due course

Following completion of the 2024 drill program at Lo Herma, GTI intends to publish an updated mineral resource estimate and exploration target range for the project. The Company expects that the updated mineral resource estimate will support near-term development of a Scoping Study to demonstrate the economic potential of the project.

GTI Executive Director Bruce Lane commented, “We are pleased and excited to have received investor support and funding to continue moving forward with our planned resource expansion drilling at Lo Herma. Matt and the team in Wyoming have put us in a great position to complete the drilling program this quarter, with a revised mineral resource estimate to be rapidly advanced post-drilling. This work prepares GTI for a potential Lo Herma scoping study which we hope to commence later this year on the basis that we can significantly grow the uranium resource estimate to a similar scale to ISR uranium mines currently being constructed or planned in Wyoming at Ur-Energy’s Shirley Basin project & Encore’s Energy’s Gas Hills project.”

LO HERMA GEOLOGIC SUMMARY

The Lo Herma project is located on the southern end of the west flank of the Powder River Basin (PRB), a regional asymmetric synclinal basin hosting a sedimentary rock sequence of about 15,000 feet in the deeper portions of the basin. The basin is bounded by the Bighorn Mountains on the west, the Black Hills to the east, and the Casper Arch, Laramie Mountains, and Hartville Uplift along the southern margin. Along the edges of the basin, progressively older sedimentary units outcrop at the surface as you move away from the synclinal axis of the basin.

The target host geology for Lo Herma project is located in and around the contact of the Eocene Wasatch Formation (Wasatch) and the Paleocene Fort Union Formation (Fort Union).
