Arnot OpCo is a proudly South African coal producer located in Mpumalanga, south of the N4 corridor. Established in 2019 through a landmark worker-empowerment transaction, the company was formed when ownership of the Arnot Mine was transferred to former employees at no cost, creating one of South Africa's most significant employee-owned mining operations.
The company was established through a partnership between Arnot InvestCo and Wescoal Mining, combining industry expertise with a shared commitment to sustainable mining and broad-based economic participation.
Strategically situated adjacent to the Arnot Power Station and within close proximity to the Rietkuil rail siding, Arnot OpCo benefits from well-developed infrastructure and efficient access to 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.
Arnot OpCo operates through a collaborative business model that leverages outsourced mining partnerships and specialist processing contractor support for the operation and maintenance of its Coal Handling and Processing Plant (CHPP). Existing infrastructure includes crushing and screening facilities, Dense Medium Separation (DMS) modules, and pre-certification stockpile infrastructure, enabling the efficient production of high-quality coal products.
As part of its growth strategy, the company is expanding beyond the domestic market and positioning itself to supply international seaborne customers with export-quality RB1, RB2, and RB3 coal products.
Driven by operational excellence, responsible resource development, and meaningful stakeholder participation, Arnot OpCo remains committed to supporting South Africa's energy security, creating sustainable economic value, and building a resilient future for its employees, communities, and stakeholders.
