The Yelanggou Zinc Poly-metallic deposit was discovered by means of 1:50000 stream sediment survey and identification of geochemical anomalies.There exists a structural alteration zone with limonite,which is obviously characteristics of squeeze of slice and broken rocks,above which lie mixed elements anomalies of As,Zn,W,Mo,Sb,Bi,and Ag,which have remarkable peaks and good continuity.There are squeezed lentoid bodies in the structural alteration zone,where relicts of metal sulphide are found at the central portion.Field tests have enabled identification of distinct multi-element lithogeochemical anomalies of Zn,Ag,As,Sb,Sn,W,and Mo.in the gossan zone,which have high peak values and large intensity.By means of trench exploration and collection of chemical samples,the primary haloes of the orebody on the surface are delineated.Finally,the prospect of the Yelanggou zinc poly-metallic deposit is confirmed.
