Sasol Mining mines about 40 million tons (Mt) of saleable coal a year, mostly gasification feedstock for Sasol Synfuels in Secunda and utilities coal for Sasol Infrachem in Sasolburg, both in South Africa. Sasol Mining also exports some 2, 8 Mt of coal a year. Underground mining operations are: Bosjesspruit, Brandspruit, Middelbult, Syferfontein and Twistdrei (all in the Secunda area) and Sigma near Sasolburg. As some of these mines are approaching the end of their useful lives, new developments are underway to ensure continued supply. In May 2012 we inaugurated the R3, 4 billion Thubelisha shaft at the Twistdrei colliery. This is one of our mine replacement projects, to replace 60% of Sasol Mining’s operating capacity in Secunda by 2020 at a cost of R14 billion. The Thubelisha shaft will eventually comprise an operation delivering more than eight million tons per annum (mtpa) of coal over 25 years. It is the first milestone in the large-scale replacement of our reserves. ..
