Sydvaranger is considered a typical Algoma-type banded iron deposit consisting of thinly banded to laminated quartz-magnetite iron formations. Comparable deposits include the Lake Superior-type iron formations.All of the iron deposits that comprise the Project are situated in the metamorphosed sedimentary iron formations of the Fisketind Formation. The iron formations are structurally deformed and moderately to strongly metamorphosed and have been defined over a 12 km strike length from Bjørnevatn in the north to Kjellmansåsen in the south. More than 23 separate iron deposits have been identified in the region to date.The stratigraphic rock units relevant to the iron ore deposits are the Fisketind and Bjørnefjell Formations of the Bjørnevatn Group. The Fisketind Formation contains all the economically important iron formations, whereas most of the waste that has to be mined comprises the Bjørnefjell Formation. The principal and best-known parts of the Fisketind iron formations are the Bjørnevatn West and East deposits located in the northern portion of the syncline within the central part of the Sydvaranger mining area.Throughout the Sydvaranger deposit, the magnetite occurs in thin bands up to several millimetres in thickness laminated together with quartz and amphiboles. The amount of magnetite and gangue minerals is variable in different layers of the deposit. The amount of sulphides present in the mineralisation is generally very low with only occasional thin veins and disseminations of pyrite and pyrrhotite. Sulphides generally occur in shear zones, mylonite, and brecciation structures.
