South Africa's first school of aviation, to train pilots for the proposed South African Aviation Corps (SAAC), was established in Kimberley in 1913. [29] Known as Paterson's Aviation Syndicate School of Flying , it is commemorated in the Pioneers of Aviation Museum (and replica of the first Compton Patterson Biplane preserved there), situated ...

Haib, at the border with South Africa, is a classic porphyry copper-gold-molybdenum deposit featuring oxide and sulphide copper with a predominance of chalcopyrite in the sulphide ores. Salt is recovered on a large scale from coastal solar evaporation pans in the Swakopmund and Walvis Bay areas, and at Cape Cross. The Okorusu Fluorspar Mine ...
These kimberlites are also the youngest kimberlites in the world by over thirty million years, cosmogenic helium-3 dates of olivine indicates they were erupted in the late Pleistocene-Holocene, [15] some indicated ages being 11,200 ± 7,800 ± and 12,400 ± 4,800. [3] A poorly constrained U-Pb date is 0 ± 29 million years. The cones display a ...
The discovery of diamonds led to a high demand for black labour. The self-sufficiency and independence of the African rural homestead was questioned by the British government [7] which also contributed to the acceleration of land dispossession, especially in the 1870s. This created a large black migrant population in Kimberley.

Lesotho shares many commonalities with the geology of South Africa, with Kaapvaal Craton crystalline basement rock that formed 3.6 to 2.5 billion years ago. Geologists have gleaned insights into Lesotho's deep past through extrapolation from South Africa, xenoliths extracted from kimberlite pipes and other data from drilling.
