Overview
Leningradslanets was a Russian oil-shale mining company headquartered in Slantsy, in Leningrad Oblast. Established in 1934, its principal role was to extract and supply oil shale to Zavod Slantsy, an industrial complex associated with the processing of shale into oil and other products. The company operated a succession of underground mines in and around Slantsy and later incorporated the Kashpirskaya oil-shale mine near Syzran in the Volga region. Its operating history was shaped by wartime relocation, changing industrial customers, mine consolidation, and the declining economic position of oil-shale production. During the Second World War, the company was evacuated to what is now Samara Oblast, where it worked with the Kashpirskoye and Savelyevskoye deposits. It returned to Slantsy in 1944 and expanded its local mining base through the opening of Mine No. 1 in 1947, Mine No. 2 in 1949, and Mine No. 3 in 1953. The Kirovskaya mine, which had opened in 1934, resumed operations in 1954 after the wartime disruption. The company later consolidated its mine network. Mines No. 1 and No. 2 were combined in 1970 to form the Leningradskaya Mine, while the Kashpirskaya mine was brought into Leningradslanets in 1974. Kirovskaya closed in 1988. Mine No. 3 was merged with Leningradskaya in 2003, and the combined Leningradskaya operation closed in 2010. Plans were also discussed for a new Kirovskaya mine and the Mezdureche open-pit mine, but these projects did not restore the company's long-term viability. Leningradslanets produced 1.12 million tonnes of oil shale in 2002. Its traditional customer, Zavod Slantsy, stopped producing shale oil in 2003. Oil shale was subsequently supplied to the Narva Power Plants in Estonia until 2005, and the company then suspended operations until mining restarted in 2007. In 2009, it exported 40,000 tonnes of oil shale to VKG Oil, another Estonian shale-processing company. A possible acquisition by SK Group was reported in 2006, but no agreement was reached. Leningradslanets declared insolvency in 2013 and was dissolved. At that time, more than 80% of its shares were controlled by Viktor Vekselberg's Renova Group.
History
Leningradslanets was established in 1934 as an oil-shale mining enterprise serving the industrial complex at Zavod Slantsy in Leningrad Oblast. The Kirovskaya oil-shale mine opened in the same year, establishing the mining activity around which the company developed. Its role was primarily upstream: extracting oil shale and delivering the raw material to processing and energy users rather than marketing a broad range of finished consumer products. The Second World War substantially disrupted the company's operations. In 1941, Leningradslanets was evacuated to the area that is now Samara Oblast. There it worked with the Kashpirskoye and Savelyevskoye deposits. The enterprise returned to Slantsy in 1944, after which its local production base was rebuilt and expanded. Mine No. 1 opened in 1947, Mine No. 2 in 1949, and Mine No. 3 in 1953. The Kirovskaya mine reopened in 1954. The company reorganized its mining assets as production developed. In 1970, Mines No. 1 and No. 2 were combined to create the Leningradskaya Mine. Four years later, the Kashpirskaya oil-shale mine near Syzran in the Volga region was merged into Leningradslanets, giving the enterprise an operating presence outside the Slantsy area. Kirovskaya eventually closed in 1988. In 2003, Mine No. 3 was merged with the Leningradskaya Mine; the enlarged operation was closed in 2010. Proposals were also made to develop a new Kirovskaya mine and the Mezdureche open-pit mine, but these plans did not prevent the company's eventual collapse. Leningradslanets remained dependent on the fortunes of oil-shale processing and power generation. It produced 1.12 million tonnes of oil shale in 2002. When Zavod Slantsy stopped producing shale oil in 2003, the company sought alternative customers. It supplied oil shale to the Narva Power Plants until 2005, after which it suspended its work. Mining restarted in 2007, and in 2009 the company exported 40,000 tonnes of oil shale to VKG Oil in Estonia. Ownership and restructuring efforts did not produce a lasting recovery. In 2006, SK Group was identified as a possible purchaser, but the acquisition was never agreed. By the time Leningradslanets declared insolvency in 2013, more than 80% of its shares were controlled by Viktor Vekselberg's Renova Group. The company was subsequently dissolved, ending the corporate history of a mining enterprise whose development had followed the rise, consolidation, and decline of the regional oil-shale industry.

Products and positioning
A regional extractive company focused on supplying oil shale to industrial processors and power-generation customers.
Mineral raw material
Oil shale
Oil shale was Leningradslanets' principal product. The company extracted shale from mines in the Slantsy area and from the Kashpirskaya operation near Syzran. It supplied the material to industrial processors and power-generation customers, including Zavod Slantsy, the Narva Power Plants, and VKG Oil. The company was an upstream mining supplier rather than a producer of branded consumer goods.
