Coordinates estimated.
The material is found on the limb of an isoclinal anticline, specifically the southern wing of the Zwartkoppie anticline, and its occurrence is strictly controlled by a key lithological–mechanical boundary layer. The abundant quartzite in this area is the product of hydrothermal alteration, representing the final outcome of two distinct phases of fluid-mediated transformation of the original ultrabasic rock: an early stage forming talc–carbonate schist, followed by a late stage forming fuchsite-bearing quartz schist. It is presently extracted from a strongly foliated green alteration zone.
