ROSGEO has estimated the graphite resources of the Tamga knot in Primorye

JSC Far-East PGO (Vladivostok, the subsidiary of the ROSGEO state holding) has completed works within the Tamga knot, which is prospective for the big-scaled graphite. The site is located on the territory of two administrative districts of the Primorye Territory - Lesozavodsky and Dalnerechensky (map sheets L-53-XX, L-53-XXVI of scale 1:200,000).  The study of the site with a total area of 275 km2 has been performed under the state contract for three geological seasons - from the second quarter of 2015.

The main objective of Primorye geologists was the prospecting of industrial objects of Tamga type big-scaled graphite followed by their study and inferred resources estimate by the Р1 and Р2 categories.  

“There is already one explored deposit of such graphite on the site, but its reserves are estimated at only 116 ths. tons”, said Sergey Kovalenko, Chief Geologist of JSC Far-Eastern PGO. “Our objective was prospecting of additional sites that will increase the potential of the entire knot. The territory has very good logistics: there is a transport infrastructure - road and rail, settlements. Therefore, it is quite possible to create a cluster for the production of high-quality graphite, which is currently lacking in the country.”


Geologists of Primorye divided all the works within the prospective knot into five sites; new sites were identified and previously known were studied at each of these sites. As a result, 12 graphite-containing ore bodies with industrial parameters were identified, specialists of JSC Far-East PGO estimated their total resources in 3.548 mln tons of high-quality graphite.

All materials of the three-year study, including recommendations on further geological prospecting works, will be submitted to the Client, the Subsoil Management Department for the Far-East Federal District - by the end of this year.

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.


The Far East Production Geological Association is a territorial unit of ROSGEO holding comprising four enterprises located in the Far East Federal District: JSC Primorgeologia (Primorsky Territory), Dalgeofizika (Khabarovsk Territory), Sakhalin Geological Expedition (Sakhalin Region) and Amurgeologia (Amur Region).
