SnapshotMine in Kemi, Finland is the only chrome mine in the European Union (EU).

Deep Mine expansion project:
Since 2018, Kemi mine is carrying out a Deep Mine project to increase the resource efficiency of the mine. Deepening of Kemi mine in secures our long-term chrome ore supply. New main level at 1,000 meters depth. New ore handling and hoisting system.

In the first half of the 2023 year, the expansion project of the ore concentrating plant in business area Ferrochrome was a main driver.

Deposit type

  • Intrusion related

Summary:

Kemi mines chromite deposit is part of Kemi layered intrusion. According to Huhtelin (2015) in the central part of the intrusion the main chromite layers length is around 1,9 km and average thickness is 40 m, decreasing outward from the center. The intrusion is estimated to be 3-4 km deep according to the geophysical seismic reflection surveys.

The Kemi layered intrusion has a lenticular shape, that is around 0,2-2 km wide and 15 km long according to Huhtelin (2015). Tectonic movements have tilted the intrusion to dip about 70 degrees to the northwest. The intrusion was metamorphosed during the Svecokarelidec orogeny.

The chromite layer is mainly between metaperiodate layer on the hanging wall side and basalt contact series on the footwall side. The basalt series consist of mylonitic talc-chloritecarbonate schist, talc-carbonate rock, metapyroxenite and irregular concentrates of gabbro. The basement granitoid is in contact with the talc-carbonate rock.

The ore body has been fragmented into a group of smaller ore bodies. The main orebodies illustrated in are: in northern part Pohjois-Viia (PV), in the middle Elijärvi (EL), in the western part both Surmaoja (SO) and Nuottijärvi (NJ). Smaller ore bodies are Mätäsoja (MO) to southwest-, both Länsi-Viia- (LV) and Itä-Viia- (IV) between EL and PV. The last smaller ore body is Viianmaa/Perukka (VP) to northeast from the main ore bodies. (Huhtelin, 2015).
