CanAlaska Commences Airborne Gravity Survey at Geikie Project in Athabasca Basin

22 August 2023

CanAlaska Uranium Ltd.


CanAlaska Uranium Ltd. announce it has commenced a detailed fixed-wing Falcon Airborne Gravity Gradiometer (AGG) survey on its Geikie uranium project (the “Project”) near the Athabasca Basin margin (Figure 1). The survey consists of 1,838 line-kilometres of airborne surveying at 200 m spacing across the majority of the Geikie project (Figure 2). The purpose of the AGG survey is to identify potential target areas of enhanced basement alteration associated with previously interpreted and drill defined structural corridors.

The Company recently announced results from the 2023 summer drill program representing CanAlaska’s first drill holes on the Geikie project. The drill program was focused on a 15-kilometre-long conductive structural corridor with three main target areas. Results from the program confirmed the presence of hydrothermal alteration systems hosted within a complex structural framework at Geikie which is important in the formation of basement-hosted high-grade uranium deposits. Drillholes intersected graphitic host rocks, showing evidence of multiple post-Athabasca structural reactivation events along north-south and northwest trending faults, hydrothermal alteration, and elevated radioactivity.

Early results from the Preston Creek and Aero target areas, specifically the hydrothermal alteration associated with structures, suggest that AGG surveying is an optimal geophysical tool to refine future drill targets. The AGG survey is designed to identify potential target areas where basement alteration intensifies adjacent to and within drill confirmed and regional interpreted structures. AGG surveys are focused on identifying gravity lows which are interpreted to be caused by hydrothermal fluids altering basement rocks to clay. The survey method is a proven effective tool in the exploration for basement-hosted high-grade uranium deposits in the Athabasca Basin, specifically in areas where no Athabasca sandstone cover is present. Gravity surveys have been successfully used 10 kilometres west of the Geikie project on the GMZ / ACKIO discovery, which is associated with a well-defined gravity low anomaly.

Once completed, the AGG survey results will be combined with additional high-resolution airborne geophysical data sets previously collected, including electromagnetics, radiometrics, and magnetics to validate existing targets and generate additional targets for future drill programs.

The AGG survey is being conducted by Xcalibur Multiphysics of Mississauga, Ontario. The Geikie project is currently being sole-funded by Basin Energy Limited (ASX: BSN) under an option earn-in agreement with the Company.

“I am very pleased with the teams focus on developing additional high priority drill targets on the Geikie project through completion of this critical gravity survey program. Results from this work will add immense value for optimizing future drill program targeting across this very large and underexplored project area that lies near the heart of the ‘Saudi Arabia of Uranium’, the eastern Athabasca Basin.”

Other News

The Company has started drilling at its West McArthur uranium project in the Eastern Athabasca Basin. The primary objective of the drill program is advancing the Pike Zone discovery, including continued focus on expansion of basement-hosted high-grade uranium mineralization as well as continued unconformity target testing. In addition, the Company has identified a series of high-priority resistivity drill targets along the C10S mineralized corridor, the most compelling located approximately 1.8 kilometres northeast of the high-grade Pike Zone uranium discovery.
