Store Norske Spitsbergen Kulkompani AS (SNSK) was formed in November 1916, when the company took over coal mining operations in Longyearbyen from the US-owned Arctic Coal Company. Since then, Store Norske has operated coal mines on Svalbard continually, with the exception of a period during World War II.
Store Norske Spitsbergen Kulkompani AS still has its head office in Longyearbyen. SNSK is the parent company of the Store Norske group and is 100 per cent owned by the Norwegian State. The group also includes the companies Store Norske Spitsbergen Grubekompani AS (SNSG), Store Norske Gull AS and Store Norske Boliger AS. Most of the coal production in the past was carried on in Longyearbyen. The principal activities of Store Norske are now located at Svea, 60 kilometers south of Longyearbyen. Store Norske Spitsbergen Grubekompani AS produces approximately 1.8 million tonnes of coal annually from the Svea Nord mine. In the area around Longyearbyen, mining operations are now carried out only in the Gruve 7 mine, which is in Adventdalen, 15 kilometers east of Longyearbyen. The Gruve 7 mine produces about 75 000 tonnes of coal annually. Through the company Store Norske Gull AS, Store Norske operates mineral exploration activities on Svalbard and in the counties of Finnmark and Troms on the Norwegian mainland.
