The Syferfontein Colliery was established in 1989 to supply coal to the Sasol Synthetic Fuels (SSF) Plant in Secunda. Between 1991 and 2000, coal was mined from the Highveld Coalfield with the opencast strip mining method, and underground mining commenced in 1993. Though Syferfontein was originally an open pit strip mine, the original strip mine has been decommissioned and partially backfilled and rehabilitated, and most mining occurs underground.[1] Sasol Mining describes Syferfontein as an underground mine.[2]

However, recent articles have labeled Syferfontein mine as an opencast coal mine, writing that the "far smaller Tweedraai project will replace part of the Syferfontein mine, an opencast operation."[3] A 2018 article wrote that the Syferfontein opencast operation has in part been replaced by the Tweedraai 2.5-million-ton-a-year project.[4]

But Sasol's 20-F Securities and Exchange Commission filings show that the Syferfontein coal mine produced 10.1 Mtpa of coal in 2019. [5]
