The Weiningbeishan area in the eastern section of the North Qilian orogenic belt is one of the areas with the best metallogenic conditions and the most metallogenic signs of gold polymetallic deposits in Ningxia. In recent years, the Jinchangzi gold deposit is one of the breakthroughs in exploration work in this area. Based on the previous data, this paper summarizes the ore-controlling factors and prospecting indicators of the Jinchangzi gold deposit. A multielement comprehensive prospecting model based on geological-geophysical-geochemical prospecting was constructed, and the mining area and surrounding prospecting target areas were delineated. The research shows that the ore-controlling factors of the Jinchangzi gold deposit are mainly stratigraphic and structural. Stratigraphic factor is mainly manifested in specific strata and lithological combinations, and structural factor is mainly controlled by east-west regional faults and their secondary fissures. Hematitization-limonitization, silicification, sericitization, pyritization, jarosite alteration and other surrounding rock alterations, Au-Ag-As-Sb geochemical anomalies, and medium resistivity and medium-high polarizability anomalies are the main prospecting indicators in this area. Based on ore-controlling factors and prospecting indicators, a comprehensive gold prospecting model suitable is proposed for this area. 6 prospecting target areas and 3 deep prospecting target areas are delineated based on this model. Through the geochemical profile and the deep drilling of the target area, the rationality of target area has been confirmed, providing a well tool for future prospecting work in this area.
