IP sounding anomalies can effectively reflect metallic sulfide mineralized ores and altered rocks in the Quellaveco copper deposit. The size of chargeability is related to the metallic sulfide amount of rocks, and the high or low resistivity is caused by the alteration intensity of rocks. Intense anomalous chargeability occurs in strong pyritized rocks. Intermediate anomalous chargeability is caused by copper and molybdenum (mineralized) ores. Low or intermediate resistivity anomalies occur in strongly or slightly altered rocks. Nonmineralized and nonaltered rocks show high resistivity and low or no chargeability. The inferred map of inversion results has a great significance for drilling deployment.
