Abstract

The Ozernovskoe deposit is located in the Kamchatka Peninsula, in the Far East region of the Russian Federation (RF). The Kamchatka region is located in the northern part of the Pacific Ring of Fire, and contains abundant gold mineralisation, with total resources currently assessed at approximately 30 Moz of gold. The gold deposits are clustering in several gold districts and are associated with Cenozoic volcanism and occur in a geodynamic setting of the Kamchatka–Kuril island arc. Ozernovskoe is one of the largest deposits, representing both high- and low-sulfidation types with unique mineralisation characterised by large amount of various Te–Se mineral phases dominated by selenides and sulfoselenides, and native gold.
