Sibanye-Stillwater (SBSW) has reported a 'shaft incident' at its Kloof gold mine near Johannesburg, resulting in 260 employees remaining underground. The company has emphasized that all individuals are safe, accounted for, and have been provided with food, explicitly stating they are not trapped. The incident stemmed from a rock winder skip door malfunction at a sub-shaft, which impacted multiple levels and caused some damage at level 35; repairs at level 35 have reportedly been completed.
