Overview
LARCO, formally the General Mining and Metallurgical Company S.A., was a Greek mining and metallurgy enterprise focused on the extraction of nickel-rich limonite and its processing into ferro-nickel. The company was established in 1963 by Prodromos Bodosakis-Athanasiadis and developed an integrated operating model combining open-pit mining, ore transport, and metallurgical processing. Its principal metallurgical facility was located at Larymna in central Greece. The plant was completed in 1966 and became the core of the company’s industrial system, employing most of LARCO’s workforce. A settlement for workers and their families was completed near the facility in 1968, reflecting the scale and socially embedded character of the operation. LARCO also operated mines in several Greek regions, including Euboea, Neo Kokkino, Kastoria, and Servia. The company’s main raw material was nickel-rich limonite. Most of the deposits were worked through open-pit mining, while a small portion—reported as approximately 2 percent—was extracted underground. Ore was moved to the Larymna plant for metallurgical treatment. In 1977, LARCO installed a 7.5-kilometre long-distance conveyor belt, described as the first of its kind in Europe, to reduce the cost and logistical burden of transporting ore by truck. LARCO’s output was a granular, high-purity, low-carbon ferro-nickel product. This material was used primarily, and according to the reference material exclusively, in stainless-steel production. Finished material was transported from the port of Larymna, linking the company’s mining and smelting activities to international industrial supply chains. Its positioning was therefore that of an upstream industrial materials producer rather than a consumer-facing brand. The company expanded its metallurgical capacity during the 1970s. The Euboea mines were fully exploited by 1969, and two additional electric furnaces were added at Larymna in 1972. These developments illustrate LARCO’s reliance on electric-furnace processing and on the continued integration of Greek nickel resources with domestic metallurgical infrastructure. LARCO ultimately ceased to exist as an operating company on July 25, 2022. The available reference material does not establish a successor brand, a continuing parent company, or the ownership structure at the time of closure. Its historical significance lies in its role as a major Greek nickel-mining and ferro-nickel producer, its Larymna industrial complex, and its contribution to the supply of an essential alloying material for stainless steel.
History
LARCO was founded in Greece in 1963 by Prodromos Bodosakis-Athanasiadis under the formal name General Mining and Metallurgical Company S.A. From its beginning, the enterprise was organized around the extraction of nickel-bearing ore and its conversion into ferro-nickel, an intermediate material used in stainless-steel production. The company’s industrial centre was established at Larymna. Construction of the Larymna metallurgical plant was completed in 1966, creating the processing base for ore produced from LARCO’s Greek mining properties. A settlement for workers and their families was completed in 1968, underlining the importance of the facility as both an industrial site and a local employer. LARCO operated mines in Euboea, Neo Kokkino, Kastoria, and Servia. Its principal ore was nickel-rich limonite. Mining was predominantly conducted through open pits, although a small proportion of the deposits was extracted underground. The Euboea mines were fully exploited by 1969, requiring the company’s wider mining network and metallurgical capacity to support continued production. In 1972, LARCO added two electric furnaces at Larymna. The expansion increased the plant’s processing infrastructure and reinforced the company’s integrated mining-to-metallurgy model. In 1977, it installed a 7.5-kilometre long-distance conveyor belt. The conveyor was described as Europe’s first long-distance system of its kind and was intended to lower the cost of moving ore by truck. The company’s final product was a granular, high-purity, low-carbon ferro-nickel. This output was directed to stainless-steel manufacturing and shipped through the port of Larymna. LARCO therefore operated primarily as an industrial materials supplier rather than as a consumer brand: its commercial identity was tied to mining, ore processing, furnace operations, and bulk logistics. The available reference material does not provide a complete account of later ownership, management, production volumes, financial performance, or restructuring. It does establish that LARCO’s operating life ended on July 25, 2022, when the company became defunct. No successor brand or continuing corporate structure is identified in the supplied material.

Products and positioning
An integrated Greek nickel-mining and metallurgical producer serving the industrial stainless-steel supply chain.
Mining output
Nickel-rich limonite ore
Nickel-rich limonite was the principal ore extracted from LARCO’s Greek mining properties. Deposits were worked mainly through open-pit mining, with a small underground component. The ore was transported to the Larymna metallurgical plant for processing into ferro-nickel.
Metallurgical material
Ferro-nickel
LARCO’s principal finished product was a granular, high-purity, low-carbon ferro-nickel. It was produced through the processing of nickel-rich limonite at the Larymna plant and was used in stainless-steel manufacturing. The product was shipped through the port of Larymna rather than marketed as a consumer-facing product.
