... compositions (88–73 wt.% Au) to electrum (46–27 wt.% Au), commonly associated with Sb-phases and containing significant Sb within the gold itself (1.05–2.58 wt.% Sb). From the Far West lense, aurostibite occurs as distinctive rims around gold. Although aurostibite associated with gold contains no silver...

... with composition similar to the eutectics (E 1 , E 2 ) of the experimental Au–Ag–Sb system. The dominant ore mineral is stibnite with rare native antimony, native gold and a Ag-Au alloy. Textural relationships are well established: stibnite (early) → gold → aurostibite → native antimony (late). Gold is present...

metasedimentary rocks. In these settings, native gold (Au 94 Ag 6 ) occurs in a paragenetically early assemblage in combination, maldonite (Au 2 Bi; Mal), native Bi, aurostibite (AuSb 2 ;Au-Stb), löllingite (Lö), and pyrrhotite (Po). These minerals occur as agglomerations of native Bi, gold, maldonite
