In order to discuss the deep-penetrating geochemical ore prospecting method suitable for the humid environment in southern China, this paper adjusted some experimental parameters based on the enzyme leach method to form a set of indoor and outdoor operating procedures for the analysis of amorphous manganese adsorption. We chose to verify the effectiveness of the analytical method for the adsorption of amorphous manganese at the No. 505 geological prospecting line in the Wangu Gold Mine, and compared the results with the two methods of traditional soil full-scale testing and rock measurement methods. The comparison results show that the analysis method of amorphous manganese adsorption can effectively find geochemical anomalies above the concealed ore. The leaching rate of 100 mesh samples showed the characteristics of Cl>Br>I>Au>Ag>Sb>As.The anomalous sensitivity of Au and Sb detected by the amorphous manganese adsorption analytical method is higher than that of the soil total measurement, and it agrees well with the geochemical anomaly of rock measurement.
