Sibanye-Stillwater has announced the loss of two employees at its Kloof 8 shaft near Glenharvie, South Africa, on 3 May 2026.

The incident happened during a routine shaft inspection when an inspection platform separated from the main winder conveyance, causing it to fall, fatally injuring two contractor employees.

The company is providing counselling and support to the families and colleagues of the deceased.

An investigation is under way to determine the circumstances surrounding the incident.

Sibanye-Stillwater has notified organised labour and the Department of Mineral and Petroleum Resources according to regulatory requirements.

Operations at the shaft have been halted while the investigation proceeds, although the shaft infrastructure remains undamaged.

Kloof is a mid-to-ultra-deep level gold mine located on the West Wits Line of the Witwatersrand Basin.

It sits near Randfontein and Westonaria, around 60km west of Johannesburg in Gauteng, South Africa.

The shaft had combined surface and underground gold mineral reserves of 1.6 million ounces (moz) and mineral resources of 15.6moz in 31 December 2024.

Sibanye-Stillwater operates globally as a mining and metals processing group, with a varied portfolio across five continents.

The company produces and refines platinum group metals including platinum, palladium, rhodium, iridium and ruthenium.

Additionally, it produces chrome, cobalt, copper, nickel, silver and zinc.

In November 2025, Sibanye-Stillwater and Appian Capital Advisory reached a commercial settlement, resolving a four-year dispute regarding Sibanye-Stillwater's terminated acquisition of shares in Atlantic Nickel and Mineração Vale Verde.

The agreement concluded legal proceedings initiated in January 2022, with a total payment of $215m. The parties reached a settlement ahead of the quantum trial.
