Hydrogeochemical exploration for uranium within the Athabasca Basin, northern Saskatchewan

As part of our exploration programs for unconformity-related uranium deposits, we have studied the chemistry of deep ground waters from throughout the Athabasca Basin. Samples have been collected from routine, small-diameter, exploration diamond drillholes, and we have placed considerable emphasis on ensuring that they represent true ground waters.We have measured both major and minor constituents, including various uranium daughter products. Ground-water samples collected from the vicinity of uranium mineralization have consistently high levels of uranium, radium, radon and helium. Although we have not been able to establish the maximum extent of the hydrogeochemical anomalies in this environment, we have detected anomalies at distances of up to tens of meters from known mineralization.
