The main features of PGMs in placers associated with Kamenushensky, Veresovoborsky, Svetloborsky and Nizhnetagilsky clinopyroxenite-dunite massifs are considered. It is established that each of the placer systems has its own individual association of PGMs. The Nizhnetagilsky placers are exceled by the presence of ferronickelplatinum. The placers of Svetloborsky massif are characterized by an abundance of Os-Ir-(Ru) inclusions and sulphides of PGE, as well as the formation of independent aggregates of iridium. The Kamenushensky placers are differed by the consistency of Pt-Fe minerals of early association and abundant inclusions of osmium. The placers of Veresovoborsky massif are characterized by their lack of specificity in association of PGMs.
