Mineralogical characterization of ore samples from the Cameco Resources Smith Ranch-Highlands Uranium Mine, Unit B

ln Situ Recovery (ISR) mining is used for about 47% of uranium mining globally. Regulations on restoration of mined aquifers require a return to pre-mining baseline water quality conditions, or conditions where the risk of human exposure is as low as reasonably achievable. Determining the attenuating capacity of down-gradient aquifer solids is key to quantifying this risk. Organic carbon phases and sulfides are expected to be important controls on transport of elements of concern through these materials.
