The study was greatly facilitated by underground visits to forty operating Witwatersrand gold mines. Having research projects across all operating mines and most active reef horizons provided an exceptional opportunity to appreciate the similarities and differences not revealed in a single goldfield and not expressed in the literature. Research projects with Gencor, Gold Fields of South Africa, Anglo American, Johannesburg Consolidated Industries and Rand Mines greatly progressed our understanding. At various times the research has been supported by the Richard Ward Endowment, COMRO, Australian Research Council, University of Witwatersrand, Stellenbosch University, Rands Afrikaans University (U Johannesburg), Minsaco Resources, James Cook University Key Centre, CSIRO and University of Melbourne.
