The exploration of concealed ore bodies has been the hot spot of mineral exploration, especially for the metal ore with complex ore body shape, quantitative and definite probability. Lama’s peripheral concealed copper ore body is produced in the contact zone of Huaxi west early—middle plagioclase granite porphyry and Mesozoic Jixian line Kusong wood Chick subgroup of muddy microcrystalline limestone, which belongs to typical contact. In addition, the ore body is complicated and varied, which brings great uncertainty to the resource estimation of the mining enterprises. The method of “desktop GIS + mobile GIS data integration + data processing” is adopted to overcome the shortcomings of single and delay of traditional exploration methods, to solve the “discretization” of geosurvey data, to integrate the data of geophysical and remote data, And the threedimensional visualization of the intrusive and metallogenic layers was carried out by using the Marching Cubes method in the medical field, and the shape of the ore body Changes in the forecast and forecast the southeast to the hidden ore body, mine companies to reduce the risk of exploration and mining, shorten the exploration cycle to provide data support.
