New data on the geological structure and mineralizations of the Salmagorskii ring complex have been obtained by the drilling program carried out in recent 5 years. The concentric zoning of the pluton from its periphery towards the centre is: dunite-clinopyroxenite-melilitolite-urtite-ijolite-melteigite. The copper-sulphide mineralization containing chalcopyrite, minor djerfisherite and cubanite is hosted by ijolite and melteigite. The mineralization is a product of processes of the postmagmatic remobilization of copper under the influence of a residual alkaline fluid rich in H2O, CO2, Cl, sulphur, and phosphorus.
