The article deals with the prospects of development of copper-porphyry deposits discovered within the largest ore occurrences and prospecting areas of the Russian Far East. Revaluation of large reserves of copper with associated elements account (gold, silver, molybdenum) on geological data based increases the economic justification for the development of already discovered deposits, as well as the continuation of exploration work on the identified ore occurrences. Geological exploration in a certain sequence necessitates the preparation of complex prospecting, appraisal and multifactor models for the development of large copperporphyry deposits in the Far Eastern region of the Russian Federation. Complex models of geological objects for prospecting and searches of complex copper-porphyry deposits are formed in relation to each geological and industrial type. In the article, authors offer exploration typical models to develop of complex copper-porphyry deposits at different stages of geological survey. The models show the features of the deep structure of the geological objects of the simulated class and the main features of their ore-metasomatic and geochemical zoning, as well as trends in the composition and physical properties of ore-controlling geological bodies with depth. Authors present the theoretical basis of prospecting and appraisal features, reflecting the patterns of manifestation of the studied ore-bearing areas in the Far East, Russia, leads the analysis the complex of geological and geophysical studies of the deep structure of copper-porphyry deposits, formulates methodical approaches for develop modelling of copper-porphyry type fields to increase an efficiency of a geological and economic assessment of these geological objects. These approaches make it possible to comprehensively assess the parameters of exploration and development of deposits, taking into account the export-oriented orientation and investment attractiveness of the Far Eastern region of Russia.
