Qualified comments: |
(Applies to: discovery and development) Discovered early in the 20th century; average ore grade: 31.3 % Fe, 0.1 % P and 2.5 % S; range 40 to 60 % Fe and 1 to 3 % S; production unknown; one of the 11 deposits along two belts NW of Vittangi. Resources in the Vittangi ore district, including Tervaskoski, Mänty Vathanvaara, Vathanvaara, Kuusi Nunasvaaara and Venetvuoma deposits, exceed 50 Mt of iron ore containg 22 Mt of iron; no mining. |
