GTI Energy (ASX: GTR) has commenced drilling and development of three planned groundwater monitoring wells has commenced at the Lo Herma ISR Uranium Project in Wyoming’s Powder River Basin.
The groundwater monitoring holes will facilitate testing of the hydraulic parameters within the subterranean aquifer containing the Lo Herma ore body, to confirm suitability for ISR mining. Subject to favourable weather conditions, this phase of drilling is expected to be completed in the coming weeks.
“Following the recent major uplift in Lo Herma’s uranium resource, now 50% larger at 8.57Mlbs, our immediate focus is to complete a Scoping Study in the first half of 2025,” Executive Director, Bruce Lane, said.
“This round of drilling will help confirm the orebody’s suitability for ISR mining. Results from aquifer testing and metallurgical testing should be available in February and are key inputs to the Scoping Study.”
Scoping study
GTI has engaged Wyoming based BRS Engineering Inc. (BRS) to conduct the Lo Herma Scoping Study, to be prepared in accordance with the JORC code (2012) for ASX listed companies.
BRS and GTI have maintained a long-standing relationship and BRS has significant experience with Wyoming ISR project development from exploration through to construction and rehabilitation.
As previously reported on 12/12/2024, Lo Herma drill core samples were logged and split for chemical assay and metallurgical testing. Composites were prepared for metallurgical testing under alkaline leach conditions commonly used in ISR mining operations in the Powder River Basin. Testing is progressing in line with expectation and results are expected during February 2025.
In March 2023, GTI acquired a comprehensive historical data package, with an estimated replacement value of over $15 million, for the Lo Herma region.
