A challenge in any exploration program is the generation and prioritization of exploration targets at various scales and targeting is particularly difficult at the district to camp scale. This paper combines metallogenic models and multiple scale geoscience data with mathematical models to identify potential concealed deposits. Kalatage, as a study area, is a famous VMS-type Cu (Zn)-Au ore district in Xinjiang, China in the past 10 years. The study area is located in the Paleozoic uplift along the southern margin of Tu-Ha basin in eastern Xinjiang. The newly discovered Hongshan, Honghai, Meiling, and Hongshi Cu-Au deposits occur in the superimposed Mesozoic volcanic basin upon the northern part of Late Paleozoic Dananhu-Tousuquan accretionary arc. On basis of VMS-type deposit model, geological setting and the multiple exploration data including 1:0000 gravity and magnetic data, 1:2000 TEM and IP measurements, 1:2000 lithogeochemical survey and 1:2000 geological mapping show the potential mineral resources are more than 300 Mt Cu and 100t Au in the study area (Figure 1).
