With the 2025 FOSAGAMS Gemboree having been held at the Karoo National Park (KNP) just south of Beaufort West (BW), and hosted by the Cape Town Gem and Mineral Club, Peter thought it would be prescient to compile an article on the area’s geology, mineralization, groundwater and proposed mining/fracking. This was to get everyone up to speed on those aspects before they, or at least some of them, descended on the area at Easter 2025. This article should be read in conjunction with the sister one entitled, “Geology: Cape Town to Beaufort West on the N1” also by Peter Rosewarne
