Information about the mineral resources plot
The licensed area "Amnunda" is located in the northern part of the Bauntovsky Evenk region of the Republic of Buryatia) on the left bank of the river. Tsipa in the axial part of the Babanty ridge, in the interfluve of the Amnunna (Tsipinskaya) -Tulekit-Amanak-Nimnokit rivers.
Geological characteristics of the subsoil area, indicating the presence of deposits (deposits) of minerals and reserves (resources) for them:
The claimed subsoil area is located inside the Kudur-Talikit ore zone, which is located on the right bank of the river. Tsipa and in the interfluve of the river. Tsipa-Bambuika. It occupies a significant area - more than 2000 sq. km and is a northeasterly elongated strip of metamorphosed and metamorphic primary-sedimentary and effusive-sedimentary rocks, traced from the basin of the river. Kudura (Tsipinsky) and the headwaters of the river. Kudura (Taloisky) to the headwaters of the river. Talikit.
The main orographic units of the region are the southern spurs of the South Muya ridge, the eastern part of the Babanty Mountains, the Olingdinskaya and the eastern part of the Tsipinskaya depressions. The relief of most of the region is alpine type with absolute marks of watersheds from 1400-1500 to 3067 m and the bottoms of depressions from 976 m to 1150 m. The surfaces of the depressions are swampy.
The study area is part of the Baikal fold area and is composed of Precambrian, to a lesser extent, Early Paleozoic sedimentary-metamorphic and sedimentary formations. The Archean rocks are represented by the Ileir stratum of gneisses and crystalline schists, as well as the Tuldun Formation, which contains carbonate rocks. The Lower Proterozoic formations are represented mainly by the Bamboo and Upper Bambuy formations. Sedimentary-metamorphic rocks are developed from the Upper Proterozoic stratified formations, sometimes with an admixture of volcanic material from the Shumninskaya and Tuluinskaya formations within the Muya block, as well as the Nerunda and Mukhtunnaya formations in the middle reaches of the Tsipa River.
Intrusive formations are represented by the Ikat gabbro-diabase and Barguzin complexes of the Late Proterozoic; Vendian-Cambrian deposits of the Amatkan, Bambuiskaya and Chulegminskaya formations; plutonic formations of the Early Paleozoic of the Atarkhan and Vitimkan complexes; intrusions of alkaline syenites of the Sayzhinsky complex and granite intrusions of the Bichursky complex of the Middle-Late Paleozoic and Mesozoic; intrusions of the Kunalei and Gujir complexes of the Mesozoic.
Prospects for the gold content of a subsoil area are determined by:
- the confinement of the subsoil area to the eastern part of the Muya tin-chromium-gold mineragenic zone;
- the confinement of the subsoil area to the Kudur-Talikit tungsten-gold ore cluster;
- the presence of local primary and secondary dispersion halos (Pozdnyakova, 2009);
- the subsoil area is spatially aligned with the fault zones of the northeast direction.
This makes it possible to classify the territory of the licensed area as promising for the identification of ore (primary) gold.
