The Tweefontein mine began operating "at the turn of the last century."[1] The operation, which is owned by Glencore, has two sites within it, Tweefontein North and Tweefontein South.

In 2014, the Tweefontein Optimization Project was undertaken, which "delivered a low-cost, long-life brownfield expansion that elevated Tweefontein into a modern, predominantly opencast operation that mines the rich pillar reserves that were left behind in discontinued underground workings."[1]

A 2019 Resources and Reserves report from Glencore noted that mining rights for Tweefontein North expire on 27 March 2020, and an application for a renewal was planned to be lodged in March 2020. Coal Reserves for Tweefontein North are sufficient to support a mine life of 14 years. At Tweefontein South, which is contained in the iMpunzi new order mining right, mining rights expire on 28 March 2029, though no mining was conducted here in 2019. Coal Reserves for Tweefontein South are sufficient to support a mine life of 10 years.[2]
