Power Reactor and Nuclear Fuel Development Corporation (PNC) is actively participating in several uranium exploration programs in the Athabasca Basin, Saskatchewan, Canada. Athabasca Basin hosts several large, very high-grade uranium deposits. These deposits generally have no surface expression and are spacially related to the unconformity between Helikian age sandstone and Aphebian age graphite-bearing metasedimentary basement. Outcrop exposure is very poor and geophysical surveys, particularly the time domain electromagnetic surveys (TDEM) are indispensably used to detect conductive lithologies for exploratory drilling.<BR>Electromagnetic conductors related to uranium mineralization have been successfully delineated in areas where thickness of sandstone cover exceeds 500m. This paper describes successful usage of TDEM method on PNC operated Christie Lake project in the eastern part of the Athabasca Basin.
