Abstract: Based on the existing results of geological work in Rencun Copper Mine，the geological characteristics and metallogenic model of the mining area and deposit are discussed，and the genesis and ore-controlling factors of the deposit are further studied，and a new prospecting area in the region is proposed. The deposit is a post-magmatic hydrothermal vein copper deposit，and the ore body mainly has three occurrence states. The first is a set of nearly parallel joint fissure zones and fracture zones in the north-north-west direction in the andesite layer of the second member of the Dawangshan Formation. The second is produced in the joint fissure zone of andesite and syenite porphyry vein near the contact zone between syenite porphyry and andesite. The third is produced in the tuff layer of the contact zone between the granite and the tuff layer of the Dawangshan Formation. The ore body is controlled by the contact zone，the interlayer joint fissure zone and the fracture zone in the tuff layer，which is generally veined，lenticular and layered. The Tongshan-Daquantang-Wucun copper-gold anomaly on the north and northeast side of the deposit is delineated as a prospecting area，which has certain guiding significance for the next prospecting and exploration in this area.
