The deposit that supplies global shungite trade was discovered in 1736 and not seriously mined until 1991

A 250-year industrial delay

The two operating shungite mines in Karelia, the Зажогинское месторождение (Zazhoginskoye deposit) and the Максовское месторождение (Maksovskoe deposit), supply essentially all of the shungite that enters international trade. Both deposits are in Medvezhyegorsk District, on the eastern Onega-peninsula side of the Karelian shungite belt, near the village of Tolvuya. Both were known to local Russian mining authorities for centuries before they became industrial-scale operations.

The Zazhoginskoye deposit is reported in popular Russian-language sources as having been first noted in 1736, eleven years after Peter the Great's death. The 1736 date itself is repeated across regional reference works without a primary archival citation in any source the audit could verify, so treat the year as the regionally-traditional founding date rather than an archive-confirmed one. Mining did not begin in earnest until the early 1990s. There is, in other words, a more than two-and-a-half-century gap between the geological identification of the world's largest shungite deposit and its industrial exploitation.

The Maksovskoe deposit was mined informally from the middle of the 19th century, primarily for black paint pigment. This was small-scale extraction by individual entrepreneurs, not state-organised mining. From the 1870s onward, Russian researchers including Inostrantsev examined the deposits as potential industrial fuel; geological-survey work was done; pilot extraction was attempted. By the mid-1930s all of this work was abandoned. The deposits sat undeveloped for the next 55 years.

Industrial extraction at both Zazhoginskoye and Maksovskoe began in 1991, in the post-Soviet transition period. Yu. K. Kalinin, the "father of Karelian shungite" (covered in a separate thread), founded and led the operation. The modern global shungite trade has been running for 34 years as of writing.

The Zazhoginskoye deposit, in numbers

The deposit area is approximately 22 km by 11 km. Within that area, geological survey has identified 25 separate ore bodies. Individual ore bodies range from 0.2 to 58 million tonnes of high-carbon shungite rock. The carbon-plus-silica content of the worked material varies between 83% and 88%. The geological location is at the edge of the village of Tolvuya, 1.7 km from the Lake Onega shore and 5 km from the navigable bay used for transport.

Of all the deposits, this is the one that supplies the highest-grade material, what Russian vendors call "elite" or "noble" shungite, the high-carbon shungite-1 grade that Mossman 2003 found contains the detectable fullerenes (covered in another thread).

The Maksovskoe deposit

The Maksovskoe deposit is geographically adjacent to Zazhoginskoye and is sometimes treated administratively as part of the same complex. Its reserves are around 30.2 million tonnes. The carbon content of Maksovskoe shungite is variable, ranging from 41% to 61%, averaging around 49%. This is lower-grade than Zazhoginskoye material, which is why Maksovskoe was historically mined for industrial pigment use rather than as a high-purity carbon source.

The 19th-century informal pigment extraction at Maksovskoe is one of the under-told stories of the rock. Through the entire late Imperial period, when the Russian Empire was being electrified, when railways were being built across European Russia, when the cities of Moscow and Saint Petersburg were being painted black with industrial coal soot, small Karelian operations were quietly mining shungite from Maksovskoe to make black paint. The same paint was used on iron-foundry castings, on church-railing decorations, on boats and on industrial equipment. The rock that two billion years later modern science would find to contain natural fullerenes was, in 1870, supplying the Russian Empire's black-paint industry.

Why the long delay

Several factors converged to keep industrial-scale shungite mining off the table for 250 years:

- The geological location is remote. Olonets Province / Karelia was, before the late-19th-century railway extensions, a lightly populated and economically marginal corner of the Russian Empire.
- The chemical understanding of the rock was incomplete. Until Inostrantsev's 1879/1880 paper, shungite was not formally classified. Even after the naming, it was treated as a curiosity rather than as a strategic resource.
- The industrial market was unclear. The rock could be mined for black pigment in small quantities, but in larger volumes the question of "what do you do with it?" remained unanswered. Coal was abundant and cheap. There was no fuel niche for shungite.
- The Soviet period focused on heavy industry; shungite's distinctive properties (electrical conductivity, EMF attenuation, water-purification adsorption) were not the priorities of Soviet planning.
- The mid-1930s abandonment of the geological-survey work coincided with broader Soviet political turmoil and the redirection of geological research toward strategic minerals (copper, nickel, uranium, platinum) rather than carbon-rich industrial materials.

The 1991 restart was, in effect, the first time in 250 years that the right combination of factors aligned: the Soviet system had collapsed, regional Karelian researchers had developed a body of materials-science knowledge about shungite (Yushkin's globule paper 1994 was just three years away, Buseck's fullerene paper had appeared in 1992), and a new market for the rock, initially for water filtration, later for wellness and architectural use, was emerging.

The Shunga geological monument is not part of either operation

A point worth flagging: the Шуньгский разрез (Shunga Cross-Section), the type locality where Inostrantsev first identified the rock in 1875, has been a protected geological monument since 1981. Mining is illegal there. All commercial Karelian shungite comes from Zazhoginskoye or Maksovskoe, which are extraction operations a few kilometres from the type locality but on different ground. (See the Shunga geological monument thread for the full picture, and the second deposit Kazakhstan thread for the 2002-onwards Koksu commercial operation.)

For the 19th-century black-paint pigment use:

- The trail goes cold in the easily-accessible English-language sources. Russian regional sources mention pigment extraction at Maksovskoe in passing without specific archival citation. The primary documentation would be in the Russian State Historical Archive (РГИА) trade-and-commerce funds for Olonets Province, where mid-19th-century individual-entrepreneur registration records and the regional-trade returns would record the pigment-mining operations. As of writing, no English-language work surfaces this material.

Edited 2026-05-03: flagged the 1736 discovery year as regionally-traditional rather than archive-confirmed per audit. Source-verification audit pass 2026-05-02 / 03.

Editor's note (2026 audit): shungitnpk.ru/ru/company confirms 1991 commercial mining start and ~35M tonne reserves but does NOT confirm the 1736 discovery date. Suggested edit: Find primary source for the 1736 discovery year (likely a Russian regional historical or geological source) or remove the year claim.

Edited 2026-05-03, source audit. Cited sources verified to exist; no fabricated sources detected. Where the audit could directly read the source (live English-language papers, open Russian academic articles), claims were compared against the source content and corrections applied above. Where sources were paywalled or geo-blocked at audit time, bibliographic plausibility was verified via parallel routes (publisher index pages, PubMed/PMC mirrors, cross-citations) but the source content itself was not always directly read.
