Abstarct: Geophysical methods are one of the most suitable methods that they have a wide application in prospecting and exploration of mineral deposits. Using two or more exploratory methods together and combining them with other information such as geological studies can increase the possibility of exploring and reaching promising areas. According to the evidence of mextallic and sulfide mineralization in the study area (Chumalu exploratory area), the use of induced polarization (IP) and electrical resistivity geophysical methods for prospecting and exploration of probable mineralization and doing geological studies is of great importance. The Chumalu exploratory area is located at 70 km northwest of Zanjan, which is geologically located in the Alborz-Azarbaijan magmatic arc and in the Tarom-Hashtjin mextallogenic zone. The host rock is the Eocene volcanic rocks and the Oligocene monzonite intrusive mass that have undergone propylitic-carbonate, silica, and silica-argillic hydrothermal alterations due to the injection of intrusive mass. The mineralization in the area is of the form of vein, veinlet, massive, scattered and replaced, and follows the trend of the faults and fractures that incudes galena, sphalerite, cerussite, chalcopyrite and pyrite. baxsed on the results of the geological studies conducted in this research, the mineralization characteristics of Chumalu area are of the type of lead and zinc hydrothermal deposits. According to initial geological studies and the mineral evidence in the area, IP and resistivity data acquisition were first designed and carried out in the form of 4 networks using gradient array in order to determine the anomalous limits, and then, in the form of 6 lines using dipole- dipole array in order to explore the lateral and depth limits of these anomalies. The prospecting that have been done in the area revealed some places that were apt for mineralization. Then, IP and resistivity acquisition data was processed and modeled using two-dimensional (2D) smooth inversion method using RES2DINV and ZondRes2D software packages, and the results were interpreted and validated baxsed on the results of geological studies and information obtained from trenches, mining evidence and surface outcrops. Furthermore in order to obtain a better view of subsurface anomalous areas, three-dimensional (3D) smooth inversion modeling was carried out using RES3DINV software. Also for better representation of 2D and 3D modeling results, Voxler and RockWorks software have been used. Consequently, an anomaly with an approximate east-west orientation in the south of the area has been extended on the silica-shear zone, and some anomalies with an approximate north-south orientation in the north of the area, in relation to the fractures of the basaltic deposits, which can be lixnked with lead and zinc mextallic mineralization in the area. Anomalous areas with high chargeability and medium to low resistivity values have been determined. It is worth noting, high chargeability values for some anomalies in the north of the area are probably due to the presence of scattered pyrites in depth. Finally, 13 points were proposed for drilling.
