陶金坪金矿区主要矿体均产出于新元古界板溪群五强溪组上段浅变质碎屑岩系岩层劈理化带由陡变缓的交接部位，严格受陶金坪―龙鼻桥复背斜控制，成带状分布，褪色化、硅化、毒砂化、辉锑矿化等与成矿关系密切。矿区内单个矿床规模均为小型金锑矿床，江溪垄―中都连接部位的晒谷岩矿段构造成矿条件好，重砂异常明显，预计能探明一处小型砷金矿床。芭蕉冲区域是江东湾矿段的北东延伸，伞溪坳区域水系沉积物异常明显，是下一步预查工作的选择靶区。

The main orebodies of Taojinping gold mining area,which are characterized by zonal distribution and are strictly controlled by Taojinping-Longbiqiao anticlinorium,occur in the steeply to moderate dipping transition area inside the cleavage belt of epimetamorphic clastic rock series of Wuqiangxi Formation of Neo-proterozoic Banxi Group,and the mineralization is closely related to bleaching,silicification,arsenopyritiza-tion and stibnitization.In light of that the deposits in this mining area are all small scale Au-Sb deposits,it is possible to find a small scale Au-Sb deposit at Shaiguyan Block of Jiangxilong-Zhongdu junction area since its favorable tectonic and metallogenic conditions and significant placer anomaly.Bajiaochong area,as the northeast extension of Jiangdongwan ore block,and Sanxi’ao region,with significant stream sediment anom-aly,are the target area of the future pre-survey works.
