The three MECA3 deals so far (Assmang, United Manganese of Kalahari and Hotazel Manganese Mines) are being praised for providing much-needed predictability in logistics, allowing miners to plan investments and operations with confidence.
MECA3 marks a clear departure from previous fixed quota systems - moving to a demand-driven, multi-year capacity model. This shift encourages mining companies to increase production, knowing that logistics infrastructure will be available. The agreements form part of a broader effort to boost manganese exports - from roughly 20 Mt currently to 30 Mt annually by 2030—bolstering economic growth and local development in the Northern Cape.
Industry reactions reflect a mix of optimism and caution. The 10-year MECA3 agreements with Transnet offer a welcome boost in predictability - creating a foundation for growth in copper-free battery metals like manganese, essential to global green technology transitions. However, concerns about redistribution of capacity, ongoing infrastructure decay, and broader inefficiencies at Transnet temper enthusiasm. These agreements are viewed as steps in the right direction - but won’t single-handedly resolve the structural challenges dogging South Africa’s mining logistics.
Tshipi é Ntle operates the Tshipi Borwa Mine, an open-pit manganese mine located in the mineral-rich Kalahari Manganese field near Hotazel in the Northern Cape of South Africa. Since the start of commercial production in 2012, Tshipi has grown into one of the largest manganese exporters from South Africa, with a reputation for efficient, low-cost production.
