Application of seismic techniques have become more common in uranium exploration in the Athabasca Basin over the last decade and have been highlighted by a number of challenges, failures, and successes. In total, Cameco has completed 15 separate seismic programs, and has integrated them with a number of other geophysical datasets including DC resistivity and gravity for the purpose of later stage exploration and geotechnical studies related to mine development.

High grade uranium deposits within the basin have a very small footprint when compared to other base metal deposits, and to add to the challenge of discovery, these deposits are not directly detectable by geophysical methods when under cover.

Traditional geophysical exploration for unconformity uranium deposits utilizes electromagnetics (EM), magnetics, DC resistivity, and gravity and through the interpretation of these datasets we infer the presence of ideal geology, alteration, and structure. Of these, EM is considered the “bread and butter” method; however, all of these methods suffer from a decrease in resolution with increasing distance to source. The small size of these deposits coupled with an increasing depth of exploration makes deeper penetrating geophysical techniques that preserve resolution with depth sought after to assist in solving some of the geological and geotechnical challenges associated with this geological setting.
