A detailed study of the geological and electromagnetic structure of the peripheral area of Liguo iron mine, eastern China, is presented to assess the location and amount of iron ore. This study targeted a strong magnetic anomaly in the Lixi area, west of Liguo, which is located in the northern Yuhuai platform-fold-belt between the Sihu-Jing'an depression and the Xuzhou complex anticline. We carried out a series of audiomagnetotellurics (AMT) prospecting lines to delineate the deposit and assess its potential ore reserve. An integrated analysis of the magnetic anomaly, AMT resistivity, and drill core identified the areas with the great potential for iron ore mineralization. Comparation between magnetic anomaly and the resistivities can reduce the variability of singular geophysics method. The results provide important geophysical evidence regarding the potential iron-ore resources of the Liguo area.
