In order to accelerate the prospecting work for the Yanjiao mining area in Jiangcheng City, the authors made full use of the integrated geophysical method. First, the authors delineated three exploration target areas by using high power TD IP method. Then the authors studied the ore-controlling structure in the target and its extension through AMT to find favorable metallogenic area. Drilling verification led to the discovery of three concealed Pb-Zn orebodies. 5.766 million tons of the 122 b+333 class industrial sulfur lead-zinc resources are added to the reserves of the ore deposit. The results obtained by the authors show that we can quickly identify lead-zinc anomaly body, which provides the basis for further prospecting engineering through IP method and AMT method. This is one of the effective methods to find the same type of ore deposits.
