ABSTRACT

Following petrophysical studies, geological and geophysical data compilation, the former Opemiska underground mine of the Chibougamau District was selected for conducting an experimental TDEM ground survey. Fourteen different sites confirmed the variability of the EM response associated with chalcopyrite veins, and the difficulty in relying on an equivocal signature to locate the massive sulfides. Surveys away from the veins showed a variety of responses. Petrophysical measurements and microscopic observations suggest complex interrelations between the amount of ore in the rock, fabric, texture, porosity, mineralogy and impurities, leading to a wide range of bulk conductivity values that suggest chalcopyrite might be a semiconductor at this site.
