Conclusions
Mineral future commodities:
Iron: Banded iron formations (3 deposits) and one magmatic iron
deposit (+Ti, V) Base metals: North Greenland zinc province and
East Greenland copper province
Nickel: Good potential for both Norilsk type and for Sudbury
type
Gold: Known favourable geological settings with gold and one
mine
REE: Greenland has several large world class REE deposits
