Abstract Based on geological and geochemical characteristics, this paper has summed up the integrated ore-prospecting criteria and pointed out the orientation of further prospecting work. Studies show that ore components of the ore deposit are rather simple, the anomaly elements consist mainly of Mo, Bi, Ag and subordinately of W, Sn, Zn, Cu, Pb, and only Mo can form fairly large anomalies. The horizontal zoning of the elements is (Mo-Bi-Ag)-(W-Sn)-(Pb-Zn-Cu),and the vertical zoning is (Mo-Ag-Pb-Zn)-Cu-(Bi-W-Sn). The formula w(Mo)/ ≥65,≥25 can be used to predict the existence or nonexistence of blind ore bodies at depth.
