Strategically located adjacent to the Arnot Power Station and in close proximity to the Rietkuil rail siding, Arnot OpCo benefits from well-developed infrastructure and efficient access to both domestic and export markets.
The operation is supported by an estimated 210 million tonnes of coal resources and more than 20 million tonnes of reserves, providing a strong foundation for long-term, sustainable production. Arnot currently produces approximately 100,000 tonnes per month from its open-cast operations, supplying coal to Eskom's Arnot Power Station, as well as other domestic customers through FOT arrangements.
