A copper-nickel mineralization with platinoids and gold was found in the olivine websterite of the Soldatskaya Mountain located in the Kamchatsky Mys Peninsular. The dominant ore components are pentlandite, as well as nickel-iron sulfide phases with high-copper content (presumably horomanite and sugakiite). Native minerals and itermetallics are presented by copper, platinum-bearing copper, gold and awaruite. The mineralization is a result of liquid immiscibility during which drops of sulfide separated from silica magma. Post-magmatic process including serpentinization provoked decomposition, recrystallization and partial redistribution of both sulfide and native mineral phases. Refs 19. Figs 5. Tables 4.
