The Confidence Reef was discovered by the Struben brothers on 18 September 1884. This sparked off a flood of prospectors to the Witwatersrand, and eventually resulted in the discovery of the Main gold reef in 1886. The first payable gold on the Rand was extracted by the Strubens on this site. It was declared a National Monument under old NMC legislation on 29 July 1983.

The Kloofendal Nature Reserve is situated in the Suburb of Kloofendal, Roodepoort. It is on the West side of Johannesburg, Midway between Westgate and Clearwater Mall. The Entrance is on Galena Street, between Topaz and Ouklip Roads, in the Suburb of Kloofendal.
It is a 110 Hectare Reserve within easy reach, of the Centre of Johannesburg and consists of pristine Highveld Vegetation with craggy Quartzite Outcrops.
