Gold deposits in black shale type have huge reserves of hard-gold. The prevailing part of reserves of native gold is in carbonaceous terrigenous deposits in Russia. These deposits are represented by objects of various scales - from small to unique (In Russia ? Olimpiada, Nezhdanin, Natalkin, May; in Uzbekistan ? Muruntau, Kokpatas, Zarmitan, Daugyztau, Amantaitau; in Kazakhstan ? Bakyrchik; in Tajikistan ? Chore; in Kyrgyzstan ? Kumtor; in the United States ? Mather Lod; in Australia ? Bendigo, Olympic Dam). The Bakyrchik deposit is located in the Kyzyl zone, cutting the basic structure of Kalba region. Ore-bearing carbonaceous shales, mudstones, siltstones and sandstones are interbedded in the Bukon suite Middle Carboniferous age. The rocks were shale intensively, contain of carbonaceous matter and sulfides (till 5-10%). Siltstones are saturated most with gold-bearing sulfides (pyrite and arsenic pyrite) containing carbonaceous matter of 0.2-0.4% in the presence of carbonate material. The ore bodies are presented system en echelon mineralized zones of considerable power (till 20 m). The composition of the ore: pyrite, arsenic pyrite, antimony, gold, marcasite, chalcopyrite, pyrrhotite, gray ores (tennantite and tetrahedrite), galena, sphalerite, cinnabar, native silver, quartz, carbonates. Auriferous are pyrite II of pyritohedron habit and acicular arsenic pyrite. The gold in both sulfides is presented in the microscopic and submicroscopic forms. Direct contact with the carbon is installed in the interval of 0.2-1.5% content only. There is a positive relationship of gold with boron, strontium and phosphorus. Ore deposits have a wide range of elements: gold, silver, lead, zinc, copper, cobalt, nickel, molybdenum, arsenic, phosphorus, boron, strontium. The arsenic content in the ores of is 0.3-1.5%. Mineralization complex polygenic nature with multiple conversion of syngenetic sedimentogene auriferous material in the fault zone of dislocation-thermal metamorphism refers to the type mineralized zones of gold-sulphide type. In terms of reserves refers to the unique.
