Abstract: The Dajinshan area is located in the Ning-Wu ore concentration zone along the Middle-Lower Yangtze metallogenic belt at the northern margin of  Yangtze plate. The area has favorable geological conditions for mineralization and shows potential for further prospecting. To identify the prospecting potentials in Dajinshan area, this study performed a correlation analysis between induced polarization(IP) medium gradient survey and soil geochemical survey results. The results show that a NW-trending fractured and broken zone exhibits high resistance and chargeability anomalies, which are indicative of controlling mineralization. These anomalies can thus serve as indirect guides for prospecting. Ten comprehensive anomalies were identified through soil geochemical surveys that indicate significant prospecting potential. Two drill holes were drilled in areas where high resistance, chargeability, and strong Au anomalies overlapped, leading to the discovery of three copper orebodies and three pyrite orebodies, achieving a major prospecting advancement. By comparing these findings with similar metallogenic characteristics (Dalinggang gold-copper deposit, Nanmentou copper deposit), and analyzing the primary halo in drill core samples, it is believed that the deeper parts of the Dajinshan area likely have promising prospecting potentials. Based on the ore-bearing rocks, tectonic environment, and the discovery of porphyritic monzonite granites in the deeper parts of porphyry-type copper-gold deposits, it is believed that blind orebodies may exist at depth, suggesting the potential for porphyry-type copper-gold deposits.
