Abstract The exploration of deep concealed ore deposits is the main task at present. A lot of electrical measurements have been completed in Xilin Gol League of Inner Mongolia in recent years, which mainly consist of high-power IP and CSAMT or their combinational methods, with good prospecting results achieved. High-power IP measurement was used for discovery and delineation of mineralization limits and distribution of structures in the ore district; Inversion of resistivity of CSAMT section was conducted to deduce underground electrical characteristics of lithology, geological structure, attitude of structure, and size and space of ore (mineralized) body. The results achieved by the authors provide the basis for the drilling. This paper describes the exploration process of a certain deep concealed lead-zinc deposit in Inner Mongolia and makes interpretation.
