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.
