A gold mining area in Guangxi is located in the middle of Dayaoshan ore belt.Due to the exhausted mining of shallow minerals，the gold deposit is faced with the dilemma of resource exhaustion.From 2013 to 2015，relevant departments have successively carried out geological survey in this gold mining area，but these work only focused on the geological phenomena found on the surface，and did not consider the tectonic distribution closely related to mineralization，which could not meet the requirements of deep prospecting. According to the characteristics of high polarizability and low resistivity of metallogenic types in this area，and in order to meet the exploration requirements of deep prospecting，double frequency induced polarization（IP） method was selected to carry out a series of exploration work.The method of this work mainly includes the gradient induced polarization and the IP sound.According to the geological data，the wide distribution of carbonaceous rocks in the area makes the overall resistivity low，which on the one hand improves the probability of finding anomalies and is conducive to the search for gold deposits，on the other hand，increases the distribution range of abnormal bodies and interferes with the differentiation of ore-induced anomalies and the further narrowing of the prospecting target area.In this paper，by focusing on the middle or high polarization IP anomaly areas and combining with the low resistivity structural belt，the preliminary delineation of the prospecting target area is carried out.Then，IP sounding verification is carried out for the main anomaly areas and structural zones. Firstly，four IP anomalies were obtained and five structural zones were divided by the apparent amplitude frequency and the apparent resistivity.The results show that the anomalous No.1 coincides well with the structural zone No.1，both of which show a strip-like anomaly along the east-west direction，which is consistent with the predicted main ore tectonic trend.It is speculated that the anomaly is caused by the carbonaceous strata and metal sulfides around the fault zone or fracture zone，and the possibility of gold-bearing deposits in this area is very high.The anomalous No.2 is located in the intersection zone of the structural zone No.2 and the structural zone No.4. It is speculated that there are carbonaceous strata and metal sulfides in this area，and the possibility of gold deposits is high. The anomalous No.3 is located at the intersection of the structural zone No.3 and the structural zone No.5，and tends to extend northward. It is presumed that the anomaly is mainly caused by carbonaceous strata，and the possibility of gold deposits is general.There is no control of the corresponding structural zone in the anomalous No.4 area，so it is impossible to determine the prospecting prospects of the anomaly.According to the exploration results above，3 main prospecting targets were finally delineated.By comparing with inversion of the IP souding and later drilling data，the guiding significance of dual-frequency IP method for prospecting in this gold mining area is verified，which provides a scientific basis for further geological exploration work，and also provides a design idea for carrying out related electrical work in the future.
