Uranium Potential in Greenland

The uranium potential in Greenland is considered high with several known uranium occurrences. South Greenland is the largest uranium province in Greenland, containing the Kvanefjeld REE-U-Zn-F deposit, the Motzfeldt Centre and the Grønnedal-Ika complex, which are all large Mesoproterozoic alkaline Gardar intrusions. In West Greenland, several large carbonate intrusions (e.g. Sarfartoq and Qaqqaarsuk) contain elevated uranium concentrations. In East Greenland, mineralised zones are located in volcanic and granitic rocks of Devonian age at Randbøldal, Foldaelv and Moskusokseland. Given the very limited uranium exploration carried out in Greenland to date, a greater potential is presumed to exist based on spot observations and the knowledge of favourable geological environments. The highest potential for undiscovered uranium in Greenland is expected for sandstone type, unconformity type, vein type and intrusion type deposits in the well-known uranium province in South Greenland, in sandstones, veins and intrusions in West and East Greenland, and in the Mesoproterozoic- Neoproterozoic Thule Supergroup in North-West Greenland.
