3D Geological Modeling of Pulang Copper Deposit, Yunnan Province of China

The three-dimensional (3D) geological model can be applied to observe the geological subjects of the deposit from all aspects and the orientation as borehole as its geometry. In this paper, firstly, Discrete Smooth Interpolation (DSI) method with GOCAD software was applied to construct 3D topographic and geologic models of the Pulang Copper in Yunnan based on the elevation and borehole data; secondly, the 3D ore body model is constructed using both boreholes and cross-sections which are constrained by the 3D topographic and geologic models; finally, the copper reserve in this deposit was evaluated using regular block cells.
