Based on the 1∶50 000 scale of stream sediment survey results, this paper preliminarily summarizes the geochemical characteristics of 18 elements such as Cu, Au, Zn. The results indicate that the elements of Cu, Au are abundance in this area, and they have a high coefficient of variation. R–type cluster analysis shows that the element of copper has strong correlation with chalcophile elements such as Zn and Cd, while Au shows independent mineralization. The study defines 35 integrated anomalies that are mainly composed of the elements of Cu and Au. Evaluates, classifies and ranks all the anomalies, and then divided 4 A–types of anomalies, 22–B types of anomalies, 7 C–types of anomalies and 2 D–types of anomalies. Based on the metallogenic geological conditions and anomaly inspection, selects six target areas as the favorable ore–prospects in the survey area, such as Saluoyi, Xiaoshanghai–Yimaike, Gulugunnieke, Akeshare, Yangbulake and Wuluate. It suggests that the prospecting should be carried out in two directions: the VMS Cu (Zn) deposits and the magmatic–hydrothermal quartz–vein type Au (Ag) deposits.
