Basin has identified several high priority targets at its Geikie uranium project in Canada’s Athabasca Basin after completing a property-wide airborne electromagnetic survey.

Data processing is now underway for final target definition to support the planned maiden drill program.

Basin Energy’s (ASX:BSN) Geikie is strategically positioned on the eastern fringe of the basin. It features basement-hosted uranium mineralisation, with the primary target for exploration being uranium-bearing structures that intersect intercalated pelitic to psammitic gneisses and calc-silicate host rocks.

“The completion of the AEM survey is a significant milestone for our Geikie project and forms a critical step towards de-risking drill targets,” Managing Director Peter Moorhouse said.

“This is the first detailed airborne electromagnetic survey over the entirety of the project and is a significant step forward in delineating a series of high-quality, high-grade, yet shallow uranium targets.

The survey has identified a series of compelling drill ready targets in the structural intersections of the main conductor and the district scale faults observed in the magnetic data.”

Airborne EM results

While Basin had initially identified a new, significant EM conductor when it had received the initial 65% of the survey date, it has since outlined an additional conductor in the west of the project following receipt of the remaining data.

The company has classified a strong coherent northeast trending conductor which strikes through the southern half of the project as a primary target.

A series of splays and offsets of this conductor are visible, often in correlation with intersections of regionally significant deep-seated north-south trending faults, part of the Tabbernor Fault System.

Additionally, geological logs from a historical drill hole has identified structural graphite proximal to this main conductor, which the company interprets as providing confidence in the presence of structurally related graphite in the region, a known key pathfinder for uranium-rich fluid circulation and mineralisation precipitation in the Athabasca Basin.

The company has identified a series of EM anomalies associated with three of the prominent regional north-south Tabbernor faults, delineated in the airborne magnetic and radiometric survey completed in 2022.

Using analogies from known uranium mineralisation both proximal to Geikie and within the broader Athabasca Basin, it is hypothesised Tabbernor faults are structural fluid conduits, allowing deep circulation of uranium ore-forming fluids.
