Trinex Minerals (ASX:TX3) has scheduled a widespread airborne electromagnetic (EM) survey to begin at the end of June 2024 at the Gibbons Creek Project in Canada, after confirming low level uranium mineralisation.
The survey, which will cover 60% of the project, is targeting areas of known and interpreted metasediments, where historical EM surveys uncovered zones of high conductivity. Trinex says these zones are interpreted as conductive graphitic meta-pelites in the basement.
Managing Director Will Dix says the company is about to acquire detailed versatile time domain EM data over Gibbons Creek.
“Now that we are driving the exploration with the help of our technical partners at Dahrouge Geological Consulting, we are excited to develop new drilling targets utilising this dataset,” he says.
Trinex reports diamond drilling assays and downhole probe readings have confirmed the presence of anomalous uranium within the project.
Four out of five drillholes intersected uranium anomalism at or near the unconformity between the Athabasca Sandstone and underlying basement metasediments, which are variably altered.
Dix says the nature of uranium mineralisation in the region is usually poddy or nuggety, which makes it challenging to reconcile visual estimates in drill core and assays.
“Having said that, we are confident that the widespread anomalism observed in drill core and reflected in the assays is an indication that there is a larger uranium source in close proximity to the Airstrip prospect,” he says.
Further drilling at Gibbons Creek is planned for the 2024 Canadian summer period. Drilling will aim to search for fault offsets in the area of drillhole GC24-05, which can act as structural traps for the deposition of uranium.
The Gibbons Creek Uranium Project covers a 139km2 area in the northern Athabasca Basin in Saskatchewan, Canada.
The Athabasca Basin is one the world’s top sources of uranium, currently accounting for about 20% of global supply. The region is home to several major operations, including Cameco’s MacArthur River mine, which is touted as the world’s largest high-grade uranium mine.
Trinex Minerals is an Australia-based explorer with extensive holdings in Canada and Australia.
