(B) Fractured wolframite (Wolf) cemented by bismuthinite (Bit), electrum (El), hedleyite (Hed) and native bismuth (Bi) (Ferbert vein). (C) Residual lollingite (Lo) fractured and cemented by arsenopyrite (Asp) at its turn fractured and cemented by bismuthinite (Bit), electrum (El), hedleyite (Hed) and native bismuth (Bi) (Ferbert vein). (D) Fractured arsenopyrite (Asp) cemented by chalcopyrite (Ccp) with bismuthinite (Bit) inclusions, sphalerite (Sp), electrum (El) (Ferbert vein). (E) Fractured arsenopyrite (Asp) cemented by chalcopyrite (Ccp) with bismuthinite (Bit) inclusions, sphalerite (Sp), tetrahedrite (Trt), euhedral pyrite (Py) contemporaneous with euhedral quartz (Qz4) (Ferbert vein).
