East Rand Proprietary Mines (ERPM) is a 120-year-old underground gold mining operation on the Witwatersrand Basin at Boksburg, to the east of Johannesburg. The mine employs 2,740 people. It was the deepest mine in the world until 2008 at 3,585 metres depth, slightly more than the TauTona mine, also in South Africa, which was 3,581 metres at the time (in 2008 the TauTona mine completed a digging project that extended the depth of the mine by several hundred metres.) The Cason mine dump was the world highest man made mountain. This dump is currently recycled. It is a shadow of itself and will probably disappear in the near future. ==Production== Recent production figures:〔(ERPM ) DRD Gold website, accessed: 29 September 2009〕
