Sulphide minerals, in order of decreasing abundance, include arsenopyrite, pyrite, galena, sphalerite, chalcopyrite, pyrrhotite and stibnite. Gold commonly occurs with galena and arsenopyrite, with galena being considered the best indicator sulphide for gold. Arsenopyrite, up to a few percent, occurs within the veins and the wall rocks.
