ANNOTATION:

In the Chukotka Autonomous Okrug (CHAO) economy, the gold mining industry historically occupies a Central place, which leads to the high importance of assessment, issues of development and dynamics of the mineral resource base of gold. In modern Russian gold mining CHAO share — 12.2%, and its share in Russia’s total gold reserves — 3%. The present level of gold production in the district is 25 to 28 tons per year. The result of oreformation and metallogenic analysis shows that the new, undeveloped areas of CHAO the most interesting in industrial terms: riches epithermal Au-Ag deposits, such as the Kupol, Dvoynoy, etc., Au-sulfide disseminated deposits (Maysky, Tumannoe, etc.), Au-Bi deposits intrusions related (Kekurnoe, etc.), gold-quartz deposits in turbidite (Sovinoe, Skvosnoe, etc.), Cu-Au-porphyry deposits. CHAO has notable potential for development, as well as the coastal marine and technogenic gold placers.
