Abstract: By using dual-frequency induced polarization method, we carried out geophysical evaluation on a copper-molybdenum ore deposit in Mongolia, and delineated several high apparent amplitude frequency and low apparent resistivity anomaly areas caused by a number of copper-molybdenum metal ore body according to the following engineering verification. These ore bodies occur in the altered fracture zone with granodiorite and diorite. Genetically, this deposit belongs to porphyry-type copper-molybdenum deposit and its scale is medium size. Research results show that the dual-frequency induced polarization method an effective method for seeking the same type of deposit，which helps to quickly delineate copper-molybdenum mineralization anomalous bodies and provides guidance for later deployment of prospecting.

Key words: Mongolia; dual-frequency induced polarization method; copper-molybdenum ore deposit; porphyry; copper-molybdenum deposit
