Abstract：The study area lies in the Dong Ujimqin Banner iron polymetallic ore belt. Quite a few 1:50 000 geochemical anomalies are distributed in this area and characterized by predominant medium-low temperature elements, large anomaly sizes, large quantities, and high peak values. The Duolungou mining area has a 1:50 000 composite geochemical anomaly of Ag, Pb and Zn. The 1:10 000 soil survey shows that the anomaly has element concentration zoning and a good consistency with the concentration center, and can be decomposed into several secondary anomalies characterized by predominant Ag. Several alteration belts are developed in secondary anomalies, in which there exist polymetallic orebodies dominated by silver. The preliminary trenching demonstrates that the quantity of silver in a single silver sample is up to 1 332×10-6, associated with Pb-Ag orebodies. The anomalies might result from the polymetallic orebodies dominated by Ag, suggesting that this area has good prospecting potential and is expected to form another important silver polymetallic ore belt in Inner Mongolia.
