The DST-NRF Centre of Excellence (CoE) for Integrated Mineral and Energy Resource Analysis (DST-NRF CIMERA) is inviting applications for a Research Fellow to commence research on the broader aspects of the gold-bearing Witwatersrand Supergroup rocks in South Africa as soon as possible.
Gold is found in the conglomerate strata of the younger members of the Supergroup, locally referred to as banket. The abundance of this gold is without a natural equal anywhere else in the world. Over 40 000 tonnes (44 000 short tons) have been mined from these rocks since this precious metal was first discovered here in 1886. This accounts for ...
