The Bi mineralization is described in quartz-sulfde veins of the Nazarovskoe gold polymetallic deposit (Western Transbaikalia), which is localized within the Eravnino volcano-tectonic structure and is confned to the Nazarovskoe fault zone and the contact with a granodiorite pluton intruding volcanosedimentary rocks. The Bi minerals include Ag-Bi, Cu-Bi, Pb-Bi, and Ag-Pb-Bi sulfosalts, Bi sulfotellurides, aikinite, and native bismuth in assemblage with chalcopyrite and galena. Most Bi minerals are described for the frst time both for the Nazarovskoe deposit and the entire Ozerninsky ore cluster.

Keywords: Bi minerals, Nazarovskoe deposit, Western Transbaikalia, Republic of Buryatia, native bismuth, Ag-Bi, Cu-Bi, Pb-Bi, and Ag-Pb-Bi sulfosalts, Bi sulfotellurides.
