Abstract The Yinnao deposit is located in the west of the Yinkeng Au-Ag polymetallic orefield. The main mineral type is altered rock type in the fracture zone. According to the results of the soil mercury gas survey, the study area shows a significant anomaly with the maximum content of 5 200.00 ng/m3 and the largest peak/background ratio is 13.4. The anomaly shape is consistent to the NE-trending ore-controlling structure, and shows a anomaly superposition feature. Combining the distribution of mercury anomalies with ore-forming geological conditions, the authors delineated three metallogenic prospective areas, with the Ⅲ prospective area exhibiting the greatest prospecting potential.
