Miners Trapped Underground at Sibanye-Stillwater's Kloof Mine

Strategic Insights -

Two hundred and sixty miners were stuck underground at Sibanye-Stillwater's Kloof mine near Westonaria on Thursday after the door of the conveyance used to haul ore to the surface opened, causing debris to spill and damage the shaft. Fortunately, no injuries were reported, but the incident highlights the hazards of deep-level gold mining. Sibanye expects the situation to be resolved by noon on Friday, May 23, 2025.

The miners were trapped at Shaft 7, a classic ultra-deep Witwatersrand gold operation that is more than 3km deep. Sibanye is working to make the shaft safe before allowing the miners to be hoisted to the surface. The incident may be seen as a setback to Sibanye's and the wider South African mining sector's improved safety record in recent decades. The National Union of Mineworkers (NUM) expressed anger at Sibanye's delay in alerting the public to the incident.
