Terra Uranium Ltd (ASX:T92) will have diamond drills turning in a few weeks at the Pasfield Lake project in the prolific Athabasca Basin of Saskatchewan, Canada after strong helium and geophysics analyses returned indications of uranium mineralisation.
Samples taken from the reverse circulation (RC) drill hole PS-23-RC04 showed that helium concentration was 234 times greater than background, indicating there is local high-grade uranium at depth.
Discovery International Geophysics delivered the data from a ground geophysical survey over key uranium drill targets at the 100%-owned Pasfield and Parker projects, where both areas are believed to have high uranium discovery potential.
The results have been integrated into advance earth models, with drill targets now finalised for the program.
All systems go
ITL Diamond Drilling, a specialist in deeper drilling, has been contracted for the spring campaign targeting average depths of 1,200 metres.
T92 executive chairman Andrew Vigar said: “Over the last eight months, T92 has rapidly completed multiple geoscience surveys (geology, geophysics, and geochemistry) throughout our 1,000 square kilometre portfolio, with the new helium assays, Time Domain Electromagnetics and Stepwise Moving Loop Transient Electromagnetics survey results corroborating with these findings, delivering isolated multiple best-in-class Athabasca unconformity targets.
“We are confident in our rigid results-based technical framework with use of the best modern technologies for undercover depth resolution and are now ready for our first diamond drilling program, which is to commence in the next few weeks.”
A look at the projects
T92 holds a 100% interest in 22 claims covering a total of 1,008 square kilometres forming the Hawk Rock Project, the Parker Lake Project, and the Pasfield Lake Project in the Cable Bay Shear Zone (CBSZ) on the eastern side of the Athabasca Basin in northeastern Saskatchewan.
The projects are about 80 kilometres to the northwest of multiple operating large uranium mills, mines and known deposits.
The CBSZ is a major reactivated structural zone with known uranium mineralisation, but with limited exploration as the basin sediment cover is thicker than the known deposits immediately to the east.
Methods that have been used to explore include airborne and ground geophysics, including airborne electromagnetics, ambient noise tomography that can penetrate far beyond unconformity depth, RC drilling for geochemical profiling, and ground TDEM to provide the best targets before undertaking costly cored diamond drilling right into the target zones at depth.
