Sørensen
At Sørensen lujavrite occurs below a naujaite cap, but thick layers of lujavrite outcrop in the steep slopes that run between the ridge crest at 700m elevation, and Tunugdliarfik fjord. GMEL reported in mid-2010 that drilling had encountered significant intercepts of lujavrite. The results of the first hole drilled at Sørensen are reported below, and confirm the discovery of significant REE-uranium mineralization within several thick lujavrite lenses. Based on outcrop geology the lenses are broadly sub-horizontal. The grade and continuity of multi-element mineralization are particularly encouraging. A further 11 holes were drilled at Sørensen during the 2010 field season, with many encountering substantial intersections of lujavrite. Following drilling conducted in 2011, an initial mineral resource estimate has now been produced by SRK consulting.
Caption: Long section through the geological model of the Sørensen deposit. The model is constrained by both drill intersections and outcrop mapping of the lujavrite horizon. The deposit remains open to the north (left of page), with the lujavrite horizon undulating for 6km to the northern contact of the Ilimaussaq Complex where Kvanefjeld is located. Sørensen is characterised by improving grades with proximity to surface. The model was generated using Leapfrog™ software. Big Ben, a well-known tall landmark, is shown at same scale to allow an appreciation of the vertical dimensions of Sørensen.
Caption: The mineralized panel of lujavrite outcrops in the slopes to Tunugliarfik Fjord. Initial drill intercepts produced some of the most significant drill intercepts from the entire Northern Ilimaussaq Project area (KS006 – 185m @ 1.2% TREO, 442 ppm U3O8, 0.34% Zn). The slope is 700m vertically from ridge top to sea-level.
Caption: View over GMEL’s multi‐element project on the northern Ilimaussaq Complex in Greenland. Resources have been defined at Kvanefjeld and Sørensen, with Steenstrupfjeld and Zone 3 representing new areas of significant mineralisation. The distance from Kvanefjeld to Sørensen is 6 km. The deposits identified represent the outcropping, and near surface expressions of a vast ore system that is interconnected at depth.

Northern Ilimaussaq Specialty Metal
Iimaussaq Complex – Specialty Metals (Kvanefjeld) The Ilimaussaq complex is one of the most unique geological environments on the planet, and host to prolific resources of rare earth elements, uranium, and zinc. It is the type-locality for a layered peralkaline igneous complex, and is as unique in its unusual rock-types…
Kvanefjeld – REEs, uranium, zinc
Kvanefjeld – REEs, uranium, zinc Kvanefjeld is located at the northwest corner of the Ilimaussaq complex. Underlying the broad plateau is a vaste multi-element resource that includes one of the world’s largest resources of rare earth elements (as defined by JORC or NI 43-101 reporting codes), along with extensive resources…
Zone 3
Zone 3 Zone 3 is located along the northeastern margin of the Ilimaussaq Complex and features outcropping lujavrite. Geological mapping suggests that Zone 3 represents the apex of a structural culimination that focused REE-U rich lujavrite magma. Initial drill holes confirm a significant mineralized body of REE-U rich lujavrite underlies…
Steenstrupfjeld
Steenstrupfjeld Steenstrupfjeld occurs at the top of the Narsaq valley, to the immediate east of Kvanefjeld. Mineralised lujavrite outcrops and was recognized historically. However, recent drill holes that were originally intended to sterilize the adjacent plateau intersected mineralization under a thin veneer of cover up to 950m away from the…
