For some old mines, their available mineral reservoirs are rapidly decreasing and even exhausting after decades of mining. However, there may be great mineral resource potentials in their depth and margin. Thus, techniques are required to prospect new mineral recourses in deep and marginal parts of the crisis mines. With the maturing of geographical information system (GIS) techniques, the GIS-based mineral prediction and appraisal have becomes the mainstreams of the mineral resource appraisal regional resource prospectivity (Zhou et al., 2007; Carranza et al., 2008; Cassard et al., 2008). However, this line of researches only rely on 2D and 2.5D GIS, which are limited to the meet the requirement to prospect the mineral resources in 3D space, say, the deep and margin parts. On the other hand, since 1990s the techniques of 3D geological modeling (Houlding, 1994) have become more practical, which lays a solid foundation for generalizing the quantitative prediction of mineral resources to the 3D space. This paper presents a novel method that adopts 3D geological modeling, 3D spatial analysis and visualization to achieve 3D quantitative mineral prospectivity. A case study from Fenghuangshan copper deposit, China was conducted, aiming at prospecting of mineral resources in the deep parts of the old and crisis mines.
