Mining-geological and economic characteristics of lead-zinc ore deposits in the Russian Arctic

The article analyzes the possibilities for prospecting, evaluation, exploration and extraction of zinc and lead deposits in the Arctic. The reserves and resources of zinc and lead deposits and ore occurrences on the Novaya Zemlya archipelago, on Vaygach Island, in the Polar Urals and in the Northern Timan are calculated on the territory of the Russian Arctic. The predominant reserves are represented by the Pavlovskoye deposit, which is being prepared for development by JSC First Mining Company of the Rosatom State Corporation. In 2019, the design of a mining enterprise was initiated, no lead and zinc mining has been carried out within the Arctic zone. A promising object is the Saureyskoye deposit in the Polar Urals. The problem is the remoteness of the site from transport highways. It is necessary to plan the construction of a dirt road from the deposit to the railway. Cargo can then be sent to the ports of the Gulf of Ob or to the port of Indiga when it is put into operation. Lead and zinc deposits on the island of Vaygach and on the Arctic coast near Amderma were previously developed. It is necessary to reassess their reserves and to determine possible development options. The extracted ore will be transported through the port of Amderma. In the Northern Timan, reassessment of non-ferrous metal ores should be carried out in a complex (lead, zinc, molybdenum, copper, nickel). Ore mining may be appropriate in connection with the construction of the deep-water seaport of Indiga. The purpose of this article is to study the mining, geological and economic characteristics of lead-zinc ore deposits and the spatial organization of marine communications for the development of the mineral resource complex of the Arctic zone of Russia. Mining facilities in the Arctic have an important strategic importance for strengthening national security of the country.
