3D mineral prospectivity modelling is a new technique and method for mineral deposit prediction based on the multi-geological big data. In order to meet the requirement the requirement of targeting the concealed orebody, based on the theory of mineral prospectivity modelling, this paper developed a software system which can be used to model the prospectivity in 3D by adopting integration secondary development approach. This paper describes the overall system architecture and development approach, and detailed represents the the various functional modules within the system. This system combines most of the new approach and outcomes about 3D mineral prospectivity modelling, including database management model,3D geophysical forward modelling model, 3D spatial analysis model and 3D prospectivity mapping model, can be used to integrate, analyses multi-geological big data. In order to verify the suitability and effectiveness of this system, this paper introduces a case studies of Zhonggu orefield within Middle and Lower Yangtze metallogenic belt. The results show that this software not only be able to deepen and develop the theory of 3D mineral prospectivity modelling, but also provides a new method and powerful tool to delineate the prospectivity targets in 3D based on big data for future mineral exploration.
