The Shanggong Gold Ore Field is located at the southern margin of the North China Plate and in thewestern part of the Xiong’ershan gold polymetallic province, characterized by favorable geological conditions forgold mineralization. The Ganshu Gold Deposit is an important hydrothermal gold deposit at low⁃to⁃medium temperaturewithin the Shanggong Gold Ore Field. Comprehensive exploration integrating geological, geophysical, and geochemicalprospecting methods was carried out to investigate the deep extension of the F1 fault in the Ganshu Gold Deposit,aiming to achieve breakthroughs in mineral exploration. By combining controlled⁃source audio⁃frequency magnetotellu⁃rics (CSAMT) with geochemical analysis of drillhole’s primary halos, the F1 fault, occurrence of the mineralized bodies,and burial depth were inferred. Drillhole verification confirmed the existence of 3 layers of concealed orebodies atdepth, achieving a significant prospecting breakthrough in the deep section of this deposit. The prospecting resultsdemonstrate that integrated prospecting methods can rapidly identify deep concealed orebodies, providing importantinsights for prospecting similar types of gold deposits.
