The study area is a gold mining area situated about 70 km west of Johannesburg in the province of Gauteng in South Africa. It lies between 26°18'S–26°26'S latitude and 27°23'E–27°31'E longitude. Gold exploration in the area dates back to 1898, and mining has occurred since 1945 .
Data were collected from four gold mines and one platinum mine located in four of the nine provinces in South Africa in 2017. The total estimated workforce size at these mines was approximately 40 000, and the SAMI directly employed around 464 700 people at that time (personal communication, Department of Mineral Resources, 6 July 2016) [1] .
