Summary

The analytiсal and microscopical studies have shown copper pyretic ores of Gizilbulag field contain gold. As the gold is distributed nonuniformly in different factions the basic types of ores and monomineral factions of basic sulphide minerals (pyrite, chalcopirit, sphalerite), these minerals grow together. The shapes of separation and occurrence in ores, grain composition of native gold (0,001-2,0 mm) demonstrate, that the gold in field was derivated in two generations. The gold of the maiden generations was remarked in early pyrite in fine-dispersed state. The second generation it is connected to late processes of mineral formation.
