Abstract Located in the Pu'er longitudinal axial fracture belt of Lanping-Simao Mesozoic rift basin, the Paduanshan mining area possesses extremely favorable mineralization environment. Based on 1∶25 000 geochemical soil survey and an analysis of the geochemical characteristics of the elements and geological background of the area, the authors delineated 12 comprehensive anomaly areas and divided them into six integrated anomaly zones. At the AP6 comprehensive anomaly area which belongs to No.Ⅰintegrated anomaly zone, four copper orebodies and one low-grade gold orebody were discovered, and the prospecting program obtained promising result and good effect. In combination with an analysis of metallogenic geological conditions, it is reasonably believed that the Paduanshan mining area has excellent prospecting potential and is extremely favorable in search for epithermal filling metasomatic gold and copper deposits. If prospecting work is continued in this area, it is expected to get breakthrough soon.
