Optimum target area(OTA) plays an important rule in mineral resource prospecting,which is not only the end production of mineral resource assessment,but also the bridge between the mineral resource assessment and exploration plan.However,it is usually ignored or simplified owing to the incomplete cognition and being lack of technique or software.In this paper,we disscuss the OTA principles based on the geology,set up the data flow for OTA and develop the GIS-based OTA model.The Gejiu,Yunnan,southwestern China,was chosen as an example to do the demonstration research.The results demonstrate that the OTA model could reflect the properties of target areas,and can enhance the efficiency of OTA.
