Basic details of the project

Chulbonskoe transparent gangue quartz deposit is located 110 km south-east of the Nizhneangarsk village, 150 km south-west of the railway station New Uoyan (BAM).

Chulbonskoe granulated quartz deposit is located in the North-Baikal district of the Republic of Buryatia in the upper reaches of the river Namama. Discovered in 1979.

The deposit is located in the Barguzin-Yanchuyskaya quartziferous zone of Baikal province.

Productive quartz mineralization, in the form of irregularly shaped bodies, fills the mezhbudinnoe space of disturbed carbonaceous dolomites of shaly-carbonate strata. According to the content of trace elements the quartz relates to chemically pure, but contains increased amount of residual fluid phase (GLI), and therefore can not be used as a high-purity quartz melting raw material.

Chulbonskoe deposit is a lenticular quartz body subconcordant northeast strike in carbonate rocks of the Upper Proterozoic Barguzinskaya suite. Its length - 1000 m, capacity - 150 - 400 m. The content of the silica is in the range of 99.93 - 99.99%, coefficient of transparency of 30 - 60%, impurity content - first hundredths and thousandths of a percent. Total mass fraction of impurities that satisfies the requirements of JOTA-standard ranges from 9.1 g / t to 18.8 g / t (Danilevskaya L.A., Skamnitskaya L.S., Schiptsov V.V. Quartz raw Karelia, Petrozavodsk, 2004). The quartz grit derived from quartz of this deposit, according to TU 41-07-008-82 refers to the second-third grade. The quartz grit of granulated quartz corresponds TU 41-91-205-76 and is suitable for the production of optical glass and other special glasses. Quartz is suitable for use in the lighting industry in the production of fluorescent, halogen and other lamps. The yield of high purity quartz in the enrichment process of gangue quartz promising geological-genetic types ranges from 5 to 40%, averaging no more than 10 - 15.

Baikal party PGE "Baykalkvartssamotsvety" conducted a preliminary exploration of the deposit in the areas North and South. Identified several sub-parallel quartz veins ranging in length from 30 - 40 m to 220 m and a capacity of 0.5 m to 10 - 12 m, traced to a depth of 40 - 50 m.

Estimated reserves in the amount of about 759 thousand tons, resources of P1category - 50 thousand tons.

Method of mining - open. Enterprise construction period - 3 years. Putting into operation of the ore mine is planned for the second year after the construction start.

Investment costs, according to the Strategy of Socio-Economic Development of the Republic of Buryatia until 2025, are set in the amount of 707 million rubles.

Specific operational costs, taking into account the production capacity of enterprise is 1125 rubles for 1 ton of ore (adopted by analogy with site of quartz rocks Melomais (Republic of Karelia)).

Price on quartz concentrate brand SSQ-6 adopted according to JSC "Kyshtymskiy mining and processing complex" (Chelyabinsk region) in the amount of 23.8 thousand rub. / tons (excluding VAT).
