GTI Energy Ltd (ASX:GTR) has begun a geophysics program as it progresses toward a maiden mineral resource estimate (MRE) at the 12,000-acre Lo Herma ISR Uranium Project in Wyoming’s Powder River Basin uranium district.
After the completion of an airborne geophysics survey at the Lo Herma Project, the aircraft is expected to move to the company’s Green Mountain and Loki West project areas.
With uranium mineralisation at Lo Herma, Green Mountain and Loki West being sandstone-hosted, the airborne geophysics is expected to help define major sandstone channel systems, which, coupled with historical drilling data and radiometric anomalies, will aid in refining drill target definition.
High-quality exploration targets
GTI executive director Bruce Lane said: “This airborne geophysical survey is an important component of our program to advance our 100%-owned Lo Herma, Loki West & Green Mountain uranium projects.
“The airborne survey follows the results of our recent historical drilling analysis and ground reconnaissance programs that have highlighted high-quality exploration targets at all three project areas.
“This survey is also expected to help further refine and confirm drill targets ahead of planned drilling at Lo Herma during late 2023 or the first half of 2024.”
Work program
GTI has also secured additional historical data relating to Lo Herma, containing scanned original drill hole maps, internal memos, drill hole logs with assay data and interpretive geological cross-sections and trend maps produced by Pioneer Nuclear Inc.
All 1,445 historical drill logs are now digitised and compiled in the Lo Herma resource model.
Lo Herma’s initial drill targeting has been completed, with permitting ongoing for verification and exploration drilling campaign during late 2023 or the first half of 2024.
Work is continuing permitting for the planned drill program with interpreted results of the airborne geophysical survey will also be integrated into the geological and resource model for the deposit when the results come to hand in the coming weeks.
