The feasibility study of the geoelectric extraction method was conducted in the Hucun copper deposit, Anhui Province. The result shows that the geoelectro-chemical extraction method can improve anomaly contrast and hence is very suitable for detailed exploration work of weak regional geochemical anomalies. In particular, As, Sb, Se, Ag and Pb with a high anomaly contrast and a wide abnormal range are somewhat valuable for deep mineral exploration. Ba and Zn also have some indication significance. In addition, the authors measured the pH and κ_s anomalies which could effectively distinguish geoelectric extraction anomalies caused by shallow mineralization. According to the field test, the method is not suitable for thin soil bedrock outcrop area. At the same time, taking into account the considerable workload, the authors hold that the electrochemical measurements can be used to fine deep geochemical prospecting work.
