Abstract
MINERALS described from the Daggafontein Gold Mine1 were later made available to me for detailed study. They included typical brownish magnetic tabular pyrrhotite crystals 2·5 mm. wide by 0·5 mm. thick, snowing steep pyramid, prism and basal pin-acoid faces. Some were intimately associated with black nodules of a hydrocarbon and grey chlorite streaks in lumps of white, finely crystalline dickite.
