This work is very important, since geological structure is a major controlling feature in shear-hosted and greenstone-hosted gold deposits. Digital Terrain Model (DTM) images have been acquired and processed using the Hill Shade function of the software programme ER Mapper. This has enabled the acquisition of cloud-free, black and white images, of exceptional clarity and usefulness for regional scale structural work. These images are especially useful for delineating regional and semi-regional scale geological structures.
