[5] Among geologists, Jagersfontein is known as a kimberlite pipe,[6] and a prime locality for mantle xenoliths, some of which are believed to have come from depths of 300–500 km (190–310 mi).
The discovery a few weeks later of the much richer mines at Bultfontein and Du Toits Pan, followed by the great finds at De Beers and Colesberg Kop (Kimberley) caused Jagersfontein to be neglected for several years.
About 9.6 million carats (1,900 kg) of jewel-quality diamonds were extracted during the mine's century of operation, interrupted only by the two World Wars and the Great Depression.
During their time working in the mines, they lived in hostels which had strict rules for black people which included the necessity for the possession of a pass book.
The most distressing of these issues was the drought as it, compounded with the economic depression, put much pressure on migrant workers to return money back home to Basotholand.
Nonetheless, authorities in Jagersfontein took drastic action on the women involved in the strikes including an event in March 1913 where police officials sealed off the bantu location, searched each house and demanded pass books at gun-point.
