Abstract: The Yundukala Au—Cu—Co deposit in the northeastern margin of Junggar is located in the Aermantai Au—Cu—Fe—Co metallogenic belt in Xinjiang,mainly occurring in intermediate—basic volcanic rocks and later emplaced diorites.The ductile—brittle shear deformation in the mining area is strong,mineralization and alteration are developed,mainly including chalcopyritization, pyritization, carbonatitation, silicification, serpentine petrification and chloritization. The ore bodies are mainly distributed in the chalcopyritization—pyritization—silicification zone in the basalt of, and the diorite intruding in, the Middle Devonian Beitashan Formation. The ore bodies are veinlike, layerlike and irregular.The deposit is in the aeromagnetic anomalies and the geochemical anomalies composed of elements such as Au,Cu,Ag,Mo,Cr,Ni,Co. The anomalous zone extends in the northwest—southeast direction and is a good indicator for the exploration of the deposit. In this paper, the geological characteristics of the deposit is studied,the prospecting method is summarized,the comprehensive prospecting model is constructed and further prospecting direction is proposed to provide a basis for further exploration work in the mining area.
