**Abstract:** The ore mineralogy of a new promising target of the Aldan–Stanovoy gold province—the Spokoininsky cluster—is considered. Gold mineralization is represented by a volumetric, nonlinear type, unconventional for the region; it is related to elements of fold structures and reverse fault in the enclosing metamorphic basement rocks. Vein-disseminated sulfide–(pyrite)–quartz ores build up deposit-like bodies in beresites from gneisses and granite gneisses and are associated with Mesozoic igneous rocks of subalkaline formations. Mineralization is characterized by polysulfide (Fe-Cu-Pb); gold–bismuth (Au-Bi) and gold–silver–telluride (Au-Ag-Te) mineral types. Different mineral types have their own typomorphic minerals and typochemistry (fineness and impurities) of native gold. The widespread distribution of telluride mineralization and its great importance in the formation of gold mineralization on the Aldan shield is confirmed. The distribution area of bismuth (including tellurium–bismuth) mineralization in the southern part of the Aldan shield, in the zone of influence of the Stanovoy deep fault, has been identified.
