Abstract: The application of the geoelectrochemical method to prospecting for concealed lead-zinc-silver polymetallic ore deposits in the Toloi ore district within Abag Banner of Inner Mongolia has proved the effectiveness of this method in this area. Quite a few anomalies of such elements as Pb, Zn and Ag were delineated. An integration of various anomalies and the results of previous work shows that there exists a certain degree of potential in search for concealed lead-zinc-silver polymetallic deposits in this area. Four integrated anomaly districts, i.e., I, II, III and IV, were delineated, which were divided into three types of targets. These results point out the direction of ore-prospecting work in this area.
