Bismuth minerals, such as bismuthinite and native bismuth, are reported in 23% of global Au-dominant skarn deposits and in 9% of skarn deposits where Au is a by-product (Meinert, 2000, Theodore et al., 1991). Gold-bearing skarns can develop in either reduced or oxidised environments (Meinert, 2000, Theodore et al., 1991).
