Five miners went missing on Monday after they entered an "abandoned working place" at the Kloof Ikamva shaft.

Wellsted did not want to comment on what the miners were doing in an area that had been abandoned, but said the temperatures were high in that area, and that it did not have proper access to oxygen.
Sibanye-Stillwater said a "thorough" investigation into the incident would be undertaken.
