Primary pitchblende mineralization from the Collins Bay unconformity-type uranium deposit in northern Saskatchewan has been dated using the Sm-Nd method. The mineral isochron age of 1281 ± 80 Ma is in good agreement with other geologic and geochronological data, and demonstrates the potential of the Sm-Nd technique for the direct dating of hydrothermal mineral deposits.
