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 east-language: ZH-CN; mso-bidi-language: AR-SA">Ⅰeast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>and east-language: ZH-CN; mso-bidi-language: AR-SA">Ⅱeast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US> anomaly zone is in front halo of the orebody, with east-language: ZH-CN; mso-bidi-language: AR-SA">Ⅲeast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US> anomaly zone occurring in middle front of the orebody and west side of east-language: ZH-CN; mso-bidi-language: AR-SA">Ⅱeast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US> 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.
