With the country’s highest resource concentrations, Mpumalanga, Limpopo and the surrounding regions have been at the epicentre of the local coal mining industry for decades. It’s no surprise then that this is where Exxaro’s mines can be found.

The Belfast Coal mine is situated in the Mpumalanga province, 55 km East of Middelburg and 20 km South-West of Belfast. The mine forms part of the Witbank coalfield on the southern side of the N4 highway.
Belfast Coal will produce primary A-grade (6 000 kcal/kg) and secondary middling (21.5 MJ/kg) products. The coal supply forms part of the Exxaro RB1 export product, which will be railed to the Richards Bay Coal Terminal (RBCT). The mine will produce a combined total of 2.7 million tonnes per annum for a 17-year life.
Situated 20 km from Lephalale in South Africa’s Limpopo province, this open-pit mine employs 3 200 people and produces 26Mtpa final coal products, using a conventional truck and shovel operation. This mine has an estimated minable coal reserve of 3 261Mt, and a total measured coal resource of 4 719Mt, from which semi-soft coking coal, thermal coal, and metallurgical coal can be produced.
Some 22Mt of annual production is power station coal, transported directly to Eskom’s Matimba and Medupi power stations on a 7 km conveyor belt in terms of the existing supply contract. An additional 1,5Mtpa of metallurgical coal is sold domestically to the metal industry and others on short-term contracts.
Grootegeluk produces 2,5Mtpa of semi-soft coking coal, the bulk of which is railed directly to Mittal SA under a long-term supply agreement. Approximately 1Mtpa of semi-soft coking coal and thermal coal is exported through Richards Bay Coal Terminal or sold domestically.
Located approximately 80 km southeast of Pretoria in South Africa’s Mpumalanga province, Leeuwpan employs about 600 employees – excluding contractors – and produces 3.65Mtpa of thermal coal.
It is a conventional open-pit mine that uses modified terrace configurations and truck and shovel operations. Coal is processed using dense medium separation for the top coal layer (seam 4) as well as the bottom coal layer (seam 2). Crush and screen technology is also used to supply coal to the power station markets. The principal domestic markets for production are the metals and power-generating industries that consume 2,5Mtpa. Leeuwpan has a coal reserve base of about 52.9Mt and a resource (inclusive) of about 128Mt.
The Mafube mining complex is a 50/50 joint operation between Exxaro and Anglo American Coal. It is situated 30 km east of Middelburg, Mpumalanga, and 20 km north of Eskom's Arnot power station.
Mafube is an opencast coal operation, producing seaborne traded thermal coal, as well as coal for Arnot power station. The coal is conveyed and processed at the Mafube coal handling and process plant.
Situated some 20 km west of Kriel in Mpumalanga, South Africa, this mining complex comprises three mines that produce 14Mtpa of power station coal with a workforce of over 2 500 permanent employees and contractors. Matla is a fully mechanised underground mine employing continuous mining and short wall methods.
Its thermal coal is supplied to Eskom’s Matla power station in terms of a cost-plus agreement, reviewed annually, with a variable return payable by Eskom for any excess tonnage produced. The mine has a coal reserve base of 224,3Mt and a resource base (inclusive) of 752Mt.
Exxaro’s FerroAlloys ferrosilicon plant was established in 1996. Two new plants were commissioned in 2014 and 2016 respectively in order to guarantee supply of up to 12 000 tonnes of superior quality gas atomised and milled ferrosilicon (FeSi) per annum. Over the last two decades, Exxaro has developed two groundbreaking processing technologies aimed at improving beneficiation processes and the recovery of mineral products from low grade stockpiles, in-situ resources and waste dumps in order to overcome global mining challenges such as depleting reserves and resource quality issues. A key component of both the Ultra High Dense Medium Separation (UHDMS) and Ultra Fine (UF) processing technologies is the high-quality gas atomised ferrosilicon produced at Exxaro FerroAlloys. Early commercialisation projects were conducted successfully in the iron ore industry with the support of Kumba Iron Ore, where Exxaro holds a 20% shareholding in its subsidiary, the Sishen Iron Ore Company. The UHDMS and UF processes are currently being commercialised across a number of other commodities with the intent of growing the market. The production of FeSi is therefore critical to Exxaro’s long-term growth and investment strategies.
Exxaro FerroAlloys is ISO 9001, ISO 14001 and OHSAS 18001 certified and adheres to strict control measures to ensure compliance with all quality, environmental and health and safety standards. In the six years since the original certification, Exxaro FerroAlloys has successfully met the criteria of surveillance and recertification audits conducted by an external certification body.
