Abstract In order to achieve a new prospecting breakthrough in west of Shanlixu area, the authors have conducted the dual frequency IP scanning and high-power IP sounding profile work. The distribution of two structures was inferred through the study of the characteristics of IP anomalies. The IP conductivity anomalies were well reflected in the known copper mineralization position in the study area after the extraction of the secondary information of IP, and two metallogenic targets in the west of the study area were delineated according to this anomaly characteristics combined with the IP anomaly characteristics. These results show that the ore-induced anomalies in the study area could be effectively evaluated by the comprehensive analysis of IP multi-parameters and known ore bodies, which could provide the geophysical basis for the next drilling engineering verification and help geologists find copper-gold polymetallic ores in the periphery of similar mining areas.
