Three-Dimensional Computer-Based Gold Prospectivity Mapping Using Conventional Geographic Information systems, Three-Dimensional Mine Visualization Software and Custom Built Spatial Analysis Tools

Proceedings of GeoComputation ‘97 & SIRC ‘97 Effective mineral exploration requires a detailed knowledge of the factors and processes which result in the formation of economic deposits. To apply this knowledge, a sound three-dimensional understanding of the geology and structure of a region is required. In most cases, surface geology can be mapped with a high degree of accuracy, however, the geology at depth has to be inferred from geophysical methods, or through drilling programs, and is therefore mapped at much lower spatial resolution. This anisotropy in spatial-data quality, coupled with the scarcity of three dimensional geographic information systems (GIS), makes computer-based exploration at a campor districtscale very difficult.
