Abstract Prospecting potential is good in Mwombezhi area of Zambia.Two geochemical anomalies were delineated in the pre-searching of copper-cobalt ores in this area.IP measuring,trenching and drilling means were applied to verifying anomalies in some key sections.The results show that the anomalies are caused by mineralization,and the plagioclasite hornblende schist is the ore-bearing bed.Ten orebodies were delineated.Combined with the soil geochemical anomalies,IP anomalies and stratigraphic distribution,the authors infer that there exist thousands of meters of ore-bearing bed.The Cu-Co geochemical anomalies can effectively reflect the presence of copper and cobalt mineralized bodies.The soil geochemical survey method is proved to be applicable to the local landscape conditions.It is shown that the application of soil geochemical survey method to local landscape conditions is accurate,effective and rapid,and can be popularized and applied to Cu-Co prospecting in Zambia and some similar areas in central and southern Africa.
