Abstract: Bailing Gold Mine in Anqing City is a small-scale gold deposit with a formation type of hy⁃ drothermal structural fracture filling. In previous geological work，shallow gold veins were basically con⁃ trolled. In order to systematically study the geological conditions of mineralization in the mining area and ex⁃ plore deep ore bodies，this research work combines previous geological and geophysical results，and con⁃ ducts 1∶10 000 high-precision magnetic method area measurement，AMT，and induced polarization depth measurement to delineate favorable geophysical anomalies and analyze the prospecting potential. The re⁃ search results indicate that the fault structures in the area of Bone Mountain，where the C3 magnetic anoma⁃ ly zone is located，are extremely developed and consistent with the IP-1 induced polarization anomaly zone in the plane position. Combined with the results of induced polarization depth measurement，there are low resistance and high polarization anomalies in the deep part，which can be interpreted as mineralized bodies controlled by structural fracture zones. Therefore，the Bone Mountain area is a key target area for searching for hydrothermal structural fracture filled gold deposits. The A30 profile depth measurement conducted on the southwest side of Dongchong Reservoir shows that a complete high amplitude induced polarization anom⁃ aly zone with a certain scale is formed in the depth direction of the apparent polarization rate in the area，in⁃ dicating that the geological bodies causing electrical excitation anomalies have certain continuity and con⁃tent of metal elements. Combined with the mineralization model of surrounding deposits，the contact zone be⁃ tween the deep rock mass and the Yueshan Formation and Nanlinghu Formation in this area is a key target area for searching for skarn type polymetallic deposits. Comprehensive analysis suggests that the Bailing gold deposit has great potential for mineral exploration.
