Abstract
Anglogold has used 3D seismic surveys to assist in planning operations over several gold<br>mines in the Archaean Witwatersrand seidmentaiy basin. Mine planning benefits from the<br>ability of 3D seismic data to accurately image the subsurface, preventing mis-placed<br>development from incorrect geological models. The WUDL survey is the largest mineral 3D<br>survey in southern Africa at nearly 300km2. It imaged much of the Carletonville Goldfield~<br>located 80km southwest of Johannesburg, from Deelkraal G.M. in the west, to Driefontein<br>G.M. in the east. Results included the geological structure of economic targets such as the<br>Ventersdorp Contact Reef (VCR), a coherent model for the development of the region, and<br>some indication of the prospectivity of unmined ground.
