3 August 1964
The Oosthuizen family lived in a mining village called Blyvooruitzicht in Carltonville. Because of the area’s extensive underground mining, it became known for having unstable ground conditions and sinkholes.  Since 1997 the mine nearby, “blyvvor” has been owned by Durban Roodepport Deep (DRD).
