Abstract: Xibiecha area is located to the south of Jiapigou Gold District， and has favorable metallogenic geological background and conditions. Gold deposit prospecting prediction in Xibiecha area is made based on a 1：10000 ground high-precision magnetic survey and suggested that the fault is an important ore control factor of gold mineralization. Based on the metallogenic geological background， 4 magnetic anomalies are delineated， tagged by C-8， C-9， C-10 and C-11 respectively. According to the magnetic anomaly characteristics， 8 faults are inferred. F₉ fault fits the C-10 magnetic anomaly well and has favorable metallogenic conditions， and can be taken as a prospecting prospect.
