Coal miner Thungela has launched a R3.3 million fish-breeding project at the Loskop Dam Nature Reserve in Mpumalanga to restore aquatic life in the Wilge and Olifants rivers following a 2022 mine acid spill.
Thungela worked with the Mpumalanga Tourism and Parks Agency (MTPA), the Department of Water and Sanitation and aquatic scientists to rehabilitate the affected area after mine-affected water was released from Khwezela Colliery’s Kromdraai site on 14 February 2022.
Investigations revealed that the spill was caused by the actions of an illegal mining syndicate, which had stolen mining infrastructure. A failed concrete seal at the shaft led to the pollution, which affected the fish population and ecosystem in parts of the Wilge and Olifants rivers.
According to Miningweekly, the fish-breeding facility features an indoor enclosure with 27 tanks and six biofilters, alongside three larger outdoor breeding tanks. At the launch in February, 100 fish bred at the facility were released, following an earlier release of 600 fish.
Thungela’s CEO, July Ndlovu, disclosed that the company invested R1.8 million in the facility and had earmarked an additional R1.5 million to monitor the project.
The facility aims to restore biodiversity to the rivers, with ongoing research partnerships with universities. Once river conditions improve, the facility will be handed over to MTPA for operation.
Ndlovu emphasised the company’s commitment to environmental restoration. “To implement all aspects of the rehabilitation plan, which has led to the restoration of the environment to even better conditions than we found it is the legacy we want to leave.”
Mduduzi Vilakazi, CEO of the MTPA, commended the collaboration. “Our partnership with Thungela showcases the significance of united efforts in conserving our region’s valuable natural resources and enhancing community livelihoods.”
