VITIM ZOLOTOY COMPANY specializes in the management and development of projects in the gold mining industry. Currently, the company is actively developing a mining project of ore gold at the Kopylovskoye deposit with total expected gold reserves of over 20 tons.
The gold mining industry of the Lena Gold province has historically been based on the extraction of placer gold. It was only in the 60s of the 20th century that intensive searches and further exploration of indigenous metal deposits began in the region. This led to the discovery of such giants as Sukhoi Log, Vysokiy and a number of other deposits.
The Kopylovskoye deposit was discovered by the ore brigade of the Bodaibo geological expedition in 1970. In the period from 1971 to 1973, prospecting and evaluation were carried out at the ore occurrence using a complex of geological, geophysical and geochemical studies (geologist V.V. Kotkin, 1971, 1973). Significant amounts of mining and drilling were carried out.
At the first stage, using traditional exploration technology, the resources of the Kopylovsky deposit were estimated at 11 tons in the P2 category.
In 2000-2004, geological exploration work was carried out to study the Kopylovsky deposit.
The reserve assessment report was prepared on the basis of completed geological exploration and is protected in the State Resource Comission.
The reserves were estimated according to the parameters, the feasibility study of which for the Kopylovsky gold deposit was based on the results of the completed exploration work. In 2004, gold reserves of categories C1 + C2 were placed on the state balance sheet - 4,979 kg with an average content of 3.4 g/t.
In 2005, additional exploration work was carried out at the field. The results of the work are reflected in the "Report on the results of geological exploration carried out in 2005" (I.M. Aksenov, 2005). The reserves of the Kopylovskoye deposit, taking into account the 2005 exploration of the C1 + C2 category, amounted to 7,451.3 kg of gold with an average content of 3.22 g/t. The estimated resources of P1 are 10.4 tons of gold with an average content of 3.13 g/t.
In 2006, the company's geologists prepared a comprehensive program of additional exploration activities in the interests of the owner in accordance with the JORC Code. The program focused on the study of mineralization at depth and beyond the contour of proven reserves.
In 2012, an assessment of the reserves of the field was carried out based on the results of the completed exploration work. Additionally, 10 ore bodies with on-balance and off-balance reserves were identified. The increase in the copyright balance reserves of category C1+C2 of the Kopylovsky deposit amounted to 652 kg of gold with an average content of 3.1 g/t, off-balance sheet reserves of category P1 amounted to 2,615 kg of gold with an average content of 1.22 g/t.
VITIM ZOLOTOY COMPANY is completing exploration work on the entire area of the licensed area, including pilot mining.
In the near future, geological materials will be submitted for the state expertise of reserves and a technical project for the mining of the entire field will be approved.
