ROSGEO will start prospecting works for diamonds within the Menda-Barylayskaya area in Yakutia

ROSGEO will carry out prospecting geological and geophysical works on diamonds in solid rocks within the Menda-Barylayskaya area. The exploration survey will be funded from the federal budget. The relevant state contract was concluded between the holding and the Department for Subsurface Management of the Republic of Sakha.

The site is located in Khangalassky, Amginsky, Megino-Kangalassky districts of Yakutia. Studies will be conducted on the territory of 6,400 km2. The depth of the study is up to 300 m.

The following tasks are assigned to the specialists: prepare a high-quality magnetic field map that includes the results of aeromagnetic surveys at a scale of 1:25,000 and 1:10,000, identify local aeromagnetic anomalies of the pipe type and evaluate their prospects for setting up ground verification surveys, develop a deep geological-geophysical model of kimberlite field and crystalline basement of the area, identify promising areas in the rank of a cluster of kimberlite bodies for further detailed exploration.

The following works will also be performed: verification of the identified local aeromagnetic anomalies of the pipe type by ground magnetic survey and drilling operations, carrying out an experimental and methodological complex of geophysical works including electromagnetic profiling and gravitational survey, identification fo the main features of the internal structure of kimberlite bodies and determination their facial and geological-industrial type on the basis of the developed textural-genetic classification of kimberlites, an analysis of the average content of diamonds of size classes +0.5 mm (macro-diamonds) for certain sites, development of a digital database for all sampling types, localization of the kimberlite field and potential clusters of diamond-bearing kimberlite bodies on the basis of indirect and direct characteristics.

Based on the results, a forecast map of the diamond content of the Menda-Barylayskaya area of 1:100,000 scale will be drawn up, and the inferred resources for P2 category for some promising sites in the rank of the kimberlite body cluster of scale 1:50,000 and larger will be calculated, recommendations for further geological exploration works will be given.

According to the state contract, the completion of research is planned by the end of 2019.

ROSGEO is a Russian multi-industry geological holding company, which offers a full range of geological exploration services from regional surveys to stratigraphic drilling and subsoil monitoring. The holding company boasts unique expertise, particularly in marine geology and shelf operations.

ROSGEO was established by Decree No. 957 of the President of the Russian Federation dated 15 July 2011 on the basis of Tsentrgeologia, one of the oldest exploration companies in Russia. ROSGEO is a fully state-owned company.

The enterprises within the holding company operate in all eight federal districts of Russia. ROSGEO includes 53 enterprises located across the country. A total of more than 1,000 fields and deposits have been discovered by the holding’s companies, including major hydrocarbon and solid mineral deposits and fields such as the Astrakhan field (2.5 trillion cubic meters of natural gas), the Tengiz field (3.1 billion tonnes of oil), the Kovykta field (1.9 trillion cubic meters of natural gas), the Sukhoi Log deposit (about 2,000 tonnes of gold), the Kursk Magnetic Anomaly, and many others.

 ROSGEO’s subsidiaries have rich experience in implementing projects abroad: dozens of new fields and deposits have been discovered in Asia, Europe, Africa, and Latin America.

 ROSGEO clients include such companies as Gazprom, Rosneft, Lukoil, Severstal, MMC Norilsk Nickel, Itera, NLMK, Sibuglemet, BP, Chevron, and many others.
