GTI Energy Ltd (ASX:GTR) continues to make significant strides at its Lo Herma ISR uranium project in Wyoming, extending mineralisation through a comprehensive drilling program. The company has reported impressive progress, completing 87% of its 76-hole drill plan, with 13,405 meters drilled thus far. This development has sparked a notable increase in its share price, highlighting the market’s reaction to its expanding mineralised zones.
Expanding Mineralisation Trends
GTI has released results from 56 additional holes, of which 45 encountered on-trend mineralisation. Among these findings was a standout intercept measuring 6.0 feet with an equivalent uranium concentration (eU3O8) of 0.123%. This resulted in a total grade thickness (GT) of 0.903, marking it as the highest-grade intercept recorded so far. The mineralisation is observed across multiple sandstone layers, particularly in the northern part of the project.
One of the northernmost holes, LH-24-03, intersected two distinct mineralised zones: 11 feet of 0.054% eU3O8 (0.594 GT) and 6.5 feet of 0.043% eU3O8 (0.280 GT). These discoveries suggest that uranium mineralisation extends for 2 kilometers along projected trends.
Targeting Deeper Mineralisation
In addition to the ongoing success at shallower levels, GTI has moved operations to the eastern part of the project area to explore the deeper sands of the Fort Union formation. The company's drilling is targeting even greater mineralisation potential at depth. So far, the lower Wasatch formations have exhibited reliable continuity, boosting the overall confidence in the project’s geological model.
The development of the Lo Herma project is significant as it lies within Wyoming’s broader uranium sector, known for its extensive ISR (in-situ recovery) potential. The extension of mineralised zones within the lower Wasatch formation, and potentially within deeper formations like Fort Union, could play a vital role in expanding the company's uranium resource estimate.
Growing Confidence in Resource Estimate
GTI's leadership is optimistic about the potential of the current drilling campaign. Executive Director and CEO Bruce Lane expressed strong confidence in the results, particularly in the extensions to the north of the project area. Lane highlighted the promising GT values and the prospects of growing the uranium resource estimate at Lo Herma.
Lane noted that the continuity and mineralisation seen in the lower Wasatch formation sands provide optimism for further success in the upcoming drilling phases. As the program continues eastward, attention will now focus on exploring deeper mineralisation in the Fort Union formation.
These findings could be a key factor in significantly upgrading a portion of the resource to the indicated category, aligning with the company’s broader strategy of advancing Lo Herma into a world-class uranium project.
Bottomline
The extension of uranium mineralisation at GTI Energy’s Lo Herma project underscores the potential of Wyoming's uranium sector, as demonstrated by the positive drilling results. The company’s ongoing exploration of both the lower Wasatch and Fort Union formations is set to uncover even more mineralisation potential, with a view to upgrading its resource estimates. GTI Energy Ltd (ASX:GTR) is on track to continue expanding its presence in the global uranium market through consistent and strategic exploration efforts.
