... productive periods with native gold are associated with the postmagmatic stages: (a) early arsenopyrite–polysulfide stage and (b) gold–bismuth–telluride stage. The latter is composed of bismuth tellurides and sulfotellurides, native gold, bismuth, maldonite AuBi 2 , and complex Au and Bi intermetallic...

Bismuth tellurides tend to occur closer to the Main Vein, whereas Ag-tellurides are generally more common further away from the Main Vein. Folk (1990a) also speculated that the best zone for gold and silver values likely plunges...
