Overview
Stoilensky GOK is an iron ore mining and beneficiation enterprise based in Stary Oskol in Russia’s Belgorod Oblast. Its operations are located at the Stoilensk deposit in the northeastern part of the Kursk Magnetic Anomaly, one of the country’s major iron ore regions. The enterprise extracts iron ore and processes it into products used as feedstock for steelmaking, including iron ore concentrate and sinter feed. The company is associated with Novolipetsk Steel, commonly known as NLMK Group, and forms part of the group’s raw-material supply base. Its position within the steel value chain is primarily upstream: mining, crushing, beneficiation and preparation of iron-bearing materials rather than the production of finished steel products. The main operating complex is the Stoilensky Mining and Beneficiation Plant, generally abbreviated as SGOK or Stoilensky GOK. Reference material describes Stoilensky as one of Russia’s largest iron ore producers, accounting for approximately 16% of Russian iron ore production at the time of the cited Wikipedia entry. The same material states that the Stoilensk deposit contains confirmed reserves of approximately 26.6 million tonnes of high-grade iron ore and 1.4 billion tonnes of ferruginous quartzite. These figures describe the geological resource base cited for the deposit and should not be interpreted as annual production capacity. Stoilensky GOK’s commercial role is that of a large-scale supplier of iron-bearing raw materials, with output supporting steelmaking operations in Russia and potentially serving international markets. The operation’s competitive importance derives from its location in the Kursk Magnetic Anomaly, its substantial ore-bearing resource base and its integration with a major steel group. Public reference material also states that the enterprise was listed on Russia’s MICEX and RTS exchanges, although a current ticker and current standalone listing status are not established here.
History
Stoilensky GOK developed as an iron ore mining and processing enterprise in the Stary Oskol area of Belgorod Oblast. The operation is associated with the Stoilensk deposit, which lies in the northeastern section of the Kursk Magnetic Anomaly, a large geological formation known for its iron ore resources. The enterprise’s reported founding year is 1961, although the available reference material does not provide a detailed chronology of construction, commissioning or subsequent ownership changes. The defining function of Stoilensky GOK has been the extraction and beneficiation of iron-bearing material. Ore from the deposit is mined and processed at the Stoilensky Mining and Beneficiation Plant. Beneficiation separates and upgrades iron-bearing material to produce iron ore concentrate and related feedstocks for steelmaking. This makes the enterprise an upstream component of the ferrous-metals supply chain rather than a finished-steel manufacturer. The Stoilensk deposit is described in the available reference material as containing approximately 26.6 million tonnes of high-grade iron ore reserves and 1.4 billion tonnes of ferruginous quartzite. The figures indicate the scale of the resource base cited for the operation, but the source does not specify the applicable reserve classification, reporting date or annual production levels. Consequently, they are best treated as historical reference figures rather than current operating guidance. Stoilensky GOK became associated with Novolipetsk Steel, or NLMK Group, and is presented as part of that group’s raw-material platform. The relationship links the mine and processing complex to a major Russian steel producer and gives the operation strategic relevance as a source of iron-bearing inputs. Public descriptions identify Stoilensky as one of Russia’s largest iron ore companies and attribute roughly 16% of national iron ore production to it at the time of the cited account. That production-share figure is time-sensitive and is not presented here as a current market statistic. The enterprise was also described as having been listed on the MICEX and RTS exchanges in Russia. The supplied reference does not identify a ticker, listing dates or whether the standalone listing remains current after changes in corporate structure and Russian securities markets. No current executive roster, detailed product specifications, campaign history, scandal record or recent news chronology is established by the supplied sources.

Products and positioning
A large-scale, upstream iron ore supplier integrated with the Russian steel industry and associated with NLMK Group.
Iron ore products
Iron ore concentrate
A beneficiated iron-bearing product produced from mined ore and used as a raw material in steelmaking. Concentrate is the principal flagship product associated with Stoilensky GOK in the supplied reference material.
Iron ore products
Sinter feed
Prepared iron ore feedstock intended for sintering in an integrated steelmaking process. It forms part of the enterprise’s reported output of processed iron-bearing materials.
Iron ore products
Beneficiated iron ore
Processed material derived from ore mined at the Stoilensk deposit. Beneficiation improves the usefulness of the extracted material as an input to downstream steel production.
