In this study, the molybdenum prospecting target was delineated quickly by 1:10 000 geological mapping and 1:25 000 soil geochemical survey in the drainage system on the basis of optimizing 1:200 000 comprehensive anomaly of Mo-based ore-forming elements. The favorable areas for ore prospecting were delineated on the basis of comprehensive research. And then, the Chagandeersi large molybdenum deposit was discovered by exploratory drilling in Urad Rear Banner, Inner Mongolia. The result has proved that large-scale soil geochemical survey in the drainage system is crucial in search for ore deposits. The geological-geochemical prospecting criteria of this kind of deposits are summarized in this paper, and this provides reference in search for concealed ore deposits.
