Gold prospect 37 km N of Kuusamo.
The largest known gold deposit in the Palaeoproterozoic Kuusamo Schist Belt. It has been test mined, is under feasibility study by Polar Mining Oy, and presently (November 2006) has an in situ resource estimated as 3360 kg gold and 1550 t cobalt. The deposit is also enriched in Ag, Cu, Mo, Ni, REE and U.
Orogenic gold deposit with atypical metal association, is located in the Paleoproterozoic Kuusamo belt in northeastern Finland.
