This article describes the geological structure of volcano and tectonic depression in Ikarskoe ore field, composed of volcanogenic, volcanogenic-sedimentary, sub-volcanic and intrusive formations in paleogenic Bartang complex. There are detaily described the ore-controlling disjunctive structures and metasomatites, preceding and accompanying the ore field mineralization. Ore zones and bodies are marked and their parameters are shown. This article also describes the conditions for occurrence of ore zones and ore bodies; distribution character of mineralization; mineralization sequence of these ore zones and bodies; material composition of ores; forms of gold presence in the ore; technological scheme of complex extraction of valuable elements from highly-arsenic ore; deposits and predicted resources of ore and valuable elements. It was established that the issue on extracting of valuable elements (Au, Ag, Cu, Co, U, W) from ores in Ikarskoe deposit is solved only partially. Further studies are necessary for increasing of extraction of gold and accompanying valuable components from highly-arsenic ores, as well as for increasing of efficiency of operations of obtaining of cobalt-containing product. The beforehand assessed reserves and forecast resources of gold in Ikarskoe deposit confirm its belonging to middle scale objects. However, the significant opportunities are intended for expanding of its industrial prospects by recalculation of reserves according to modern conditions, as well as at the expense of other ore field objects, having the same type of mineral composition. The authors consider it extremely important to create ore mining industry, based on Ikarskoe deposit in the region of abundant labor force.
