Most studies of this mine were based on two-dimensional modeling. In this paper, a Hongtoushan Mine geological database is first built, the earth surface 3D model, the fault 3D model, the body 3D model and the stratum 3D model are then built based on 3D geological modelling and the international 3D deposit software Surpac according to the geological features of this mine. In order to extract the ore-controlling factors, some 3D spatial field models are built, including the lithology 3D field model, the fault 3D field model, the mineralization distribution model and the geophysical index 3D spatial field models such as CSAMT model and TEM model after geological spatial divisions into unit blocks. Those models can visually display the spatial distribution of the geological body, as a foundation for further stereo quantitative prospecting prediction in deep and marginal parts of Hongtoushan Mine. The obvious advantage of 3D geological modelling is shown in stereo quantitative prediction of concealed ore body, and it is of a high value in practical applications.
