Middelburg Mining Services (MMS) (formerly the Wolwekrans and Ifalethu Mines) comprises two open-cast mining operations Middelburg North and Middelburg South. The Complex is located 25km south of eMalahleni, in Mpumalanga.

This is a large-scale drag-line complex, supplemented by truck-and-shovel operations. Coal destined for the export market, is transported by rail to RBCT, and then exported largely to European markets.
MMS employs 3,578 people – 1,596 permanent employees and 1,982 contractors.
Seriti acquired the colliery from South 32 in June 2021.
Established in 1979, the complex has an expected life of mine until 2034.
