The east area of Dasaituo in Inner Mongolia is located in east section of Xilinhaote-Dongwuqi polymetallic mineralization zone with favorable ore-forming condition but less surface outcrop and largely overlaid by Quaternary system causing difficulty in ore prospecting. Soil geochemical exploration has outlined three S-N striking anomaly zones lying from west to east, based on element combination characteristics and zoning theory, signaling that east side of No Ⅰand Ⅱ anomaly zone is in front halo of the orebody, with Ⅲ anomaly zone occurring in middle front of the orebody and west side of Ⅱ anomaly zone occurring in the end halo of orebody, forming clear horizontal zoning of the anomaly, and presuming a variation trend of ore erosion from shallow to deep.
