Coal miner MC Mining has signed an offtake agreement with South African steel producer ArcelorMittal South Africa (AMSA), which will buy hard coking coal (HCC) from Phase 1 of the Makhado coking coal project. As South Africa has a limited production of high-quality metallurgical, or coking, coal, AMSA and other coke producers currently have to import HCC for the manufacture of metallurgical coke, a key ingredient in steel production.
