Now it is the priority to search new reserves in Jinehangyu gold mine for the resource of deposit is dose to be exhausted. This paper begin with analysis of the relationship between the mine area structure and mineralization, then a 3D model of ore - bodies is established by Vulcan system based on the synthetical analysis of a mass of geological maps and drilling data; the mineralization model was analyzed, accordingly the local mineralization rule of deep -deposit is deduced. At last several mineralization perspective areas is predicted for deep - deposit prospecting.
