A compartment wall at the Dikwena tailings storage facility near Brits failed on the evening of 13 August 2026, releasing a surge of mining sludge that damaged power infrastructure, interrupted rail services and reached a nearby river tributary, officials said.
Incident and immediate impacts
The sidewall failure at Samancor Chrome’s Dikwena facility occurred at about 17:30 on Thursday, 13 August when compartment 1B collapsed. The sludge travelled across access roads into parts of Northam Platinum’s Eland Mine, notably affecting the Maroelabult shaft area.
Samancor said clean-up operations began immediately and that it was co-operating fully with official investigations. No casualties were reported. The flow of tailings damaged Eskom electricity infrastructure and a railway line used for mineral transport, resulting in local power cuts and transport disruption.
Officials move in, water quality checks under way
The Department of Mineral Resources and Energy has scheduled a site visit. Minister Gwede Mantashe is due to inspect the Dikwena site at 10:00 on 17 August 2026 accompanied by departmental officials, who will receive a briefing on the incident and the ongoing investigation.
Authorities and the company are prioritising containment, clean-up and verification of water quality after contamination reached a local river tributary. Local communities and downstream users could face risks to water supply and agriculture if pollutants migrate further.
Local disruption and wider implications
The collapse highlighted how tailings incidents can ripple beyond mine boundaries. Damage to Eskom infrastructure left parts of the local network without power. The damaged railway line has interrupted mineral transport, with potential knock-on effects for logistics and nearby operations.
While the immediate focus is on mitigating harm, the incident underscores operational risks for energy‑intensive ferrochrome and chrome producers in the North West. Samancor and related ventures have recently benefited from preferential electricity arrangements, which make stable power supply integral to operations.
- Date and time of failure: 13 August 2026, about 17:30
- Facility: Dikwena tailings storage facility, compartment 1B
- Impacted sites: Northam Platinum’s Eland Mine (Maroelabult shaft), nearby river tributary
- Consequences: Power cuts, rail disruption, environmental contamination; no injuries reported
What residents and workers need to know
People living downstream or who rely on local surface water should avoid contact with discoloured water and not use untreated river water for drinking, cooking or watering livestock until authorities confirm it is safe. Workers at nearby mines and transport operators should follow safety briefings and traffic notices while clean-up and repair operations proceed.
| Action | Status |
|---|---|
| Immediate clean-up | Under way (Samancor reported teams on site) |
| Ministerial inspection | Scheduled for 17 August 2026 at 10:00 |
| Water quality verification | Ongoing |
| Rail restoration | Assessment in progress |
Samancor has told regulators it is co-operating with investigations into the cause and effects of the failure. The company did not provide a breakdown of the volume of tailings released in the initial report.
The incident has been captured and circulated on social media by local publications, showing the extent of the spill across roads and infrastructure. Provincial and national teams will need to establish the stability of remaining tailings walls and the adequacy of emergency drains and berms as part of their review.
For mineworkers and residents, the coming days will be crucial: containment work, infrastructure repairs and water tests will determine how long services and normal operations are disrupted. The ministerial visit is expected to set out next steps and possible regulatory or enforcement measures if safety or maintenance lapses are identified.
