Localities
At the type locality, the Driekop mine, Sekhukhuneland, Burgersfort, Fetakgomo Tubatse Local Municipality, Sekhukhune
District Municipality, Limpopo, South Africa, the deposit is an ultramafic
platinum group element deposit in a magnesian
dunite subvertical cylindrical pipe. The magnesian
dunite is rimmed by iron-rich
wehrlite and clinopyroxene
pegmatite. The core zone is
iron-rich dunite
and wehrlite with magnesian dunite
(Mindat)
Geversite was identified as tiny grains
in platinum concentrates. The associated minerals are
braggite, cooperite,
copper, chalcopyrite,
gold, hollingworthite,
osmiridium, laurite,
irodsmine, pentlandite,
platinum, pyrrhotite,
