Abstract: Yujiacun Mining Area, Ninglang County, Yunnan Province, is located in the northern part of the Ninglang-Xiangyun Copper-Molybdenum Metallogenic Belt on the eastern margin of the Sanjiang Metallogenic Belt. However, there are still some problems in the exploration and mining work in the mining area, and the geological prospecting has not made a breakthrough. The main reason is the lack of understanding of the metallogenic conditions and ore-controlling rules in the mining area. Therefore, based on the geological exploration data of the mining area in recent years, this paper systematically summarizes the geological characteristics of the gold-silver polymetallic mineralization belt in the mining area, and analyzes its metallogenic conditions and rules from the aspects of strata, structure, magmatic rock and surrounding rock alteration. Finally, the metallogenic model of the gold-silver polymetallic mineralization zone（M1） in the mining area is extracted in order to provide theoretical basis and technical support for geological prospecting in the area.
