GTi’s Lo Herma Project Nears Critical Aquifer Testing Amid Expanded Claim Holdings
GTi Energy has completed drilling two of three groundwater monitoring wells at its Lo Herma ISR Uranium Project, progressing critical infrastructure ahead of aquifer testing and resource development.
- Two groundwater monitoring wells completed; third well drilling underway
- Staking of 23 additional claims finalized, expanding project footprint
- Performance rights vested following a successful resource upgrade to 8.57 million pounds U3O8
- Aquifer testing and metallurgical results to inform ongoing Lo Herma Scoping Study
- Lo Herma remains GTi’s flagship asset with significant exploration targets in Wyoming
Groundwater Wells Mark Progress at Lo Herma
GTi Energy Ltd (ASX: GTR) has reported significant progress at its flagship Lo Herma ISR Uranium Project in Wyoming’s Powder River Basin, completing two of three planned groundwater monitoring wells. The third well is currently being drilled, with completion expected soon, subject to weather conditions. These wells are critical for assessing the hydraulic properties of the aquifer hosting the uranium mineralisation, a key step in confirming the suitability of in-situ recovery (ISR) mining methods.
The groundwater monitoring program will underpin aquifer testing, which alongside upcoming metallurgical test results, will feed into the ongoing Lo Herma Scoping Study. This study aims to define the project’s economic potential and operational parameters, setting the stage for future development decisions.
Expansion Through Additional Claims
In November 2024, GTi secured staking rights for 23 additional claims covering 443 acres, extending the project area along promising mineralised trends. The recent finalisation of the last eight claims previously held under Notice of Intent to Lease (NOITL) means the entire claim package is now consolidated and incorporated into updated exploration targets. This expansion enhances the project’s resource potential and provides a broader base for exploration and development activities.
Performance Rights Vesting Reflects Milestone Achievements
Following a resource upgrade announced in December 2024, which increased the Lo Herma Mineral Resource Estimate to 8.57 million pounds of U3O8 at an average grade of 630 ppm, GTi’s board has confirmed that key performance milestones tied to Class C and D Performance Rights have been met. These milestones include drilling over 10,000 meters across projects, securing new mineral claims, and achieving resource thresholds in line with JORC 2012 standards.
As a result, 75% of Class C and 50% of Class D Performance Rights have vested, providing incentive alignment for management and shareholders as the company advances its uranium assets.
Broader Project Portfolio and Exploration Targets
While Lo Herma remains the cornerstone of GTi’s portfolio, the company also holds promising projects in Wyoming’s Great Divide Basin and Green Mountain area, as well as brownfields uranium and vanadium assets in Utah’s Henry Mountains. The combined Mineral Resources across Wyoming projects now total approximately 7.53 million pounds of contained U3O8, with exploration targets suggesting potential to significantly increase this base.
GTi’s extensive drilling history at Lo Herma, now encompassing 954 drill holes, supports a robust understanding of the deposit and exploration potential. The company’s methodical approach to resource definition and infrastructure development positions it well to capitalise on the growing demand for uranium in the energy transition.
Looking Ahead
The completion of groundwater monitoring wells and claim staking are tangible milestones that bring GTi closer to defining the economic viability of Lo Herma’s ISR uranium deposit. The forthcoming aquifer testing results and metallurgical data will be pivotal in shaping the Scoping Study outcomes and informing potential development pathways.
Bottom Line?
GTi Energy’s steady progress at Lo Herma sets the stage for critical test results that will determine the project’s next phase.
Questions in the middle?
- What will the aquifer testing reveal about the feasibility of ISR mining at Lo Herma?
- How might metallurgical results impact the project’s processing strategy and costs?
- Could further exploration and claim acquisitions push GTi’s resource base beyond current estimates?
