///The No.Ⅱ breccia zone of Shajingou area is larger in scale, with complex structure. Breccia is ore-hosting rocks, gold mineralized bodies and pyritization are closely related, the mineralized body closer, the pyritization is stronger, and the polarization rate is higher, mineralized breccia rock and surrounding rock have obvious electric difference. In the No.Ⅱmineralized breccia zone, IP intermediate gradient and IP sounding job obtained better result; the authors guided the drilling project, solved the geologic problems, and verified the results.
