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 and minerals, as it is in its vast resources. The complex is located close to existing infrastructure in southern Greenland, in a setting that offers one of the most logistically-favourable development scenarios of any mining project in Greenland.

Of all emerging mineral projects in Greenland, the setting offers one of the most logistically-favourable development scenarios. Deep-water fjords provide all-year shipping access directly to the project area.

Within the Ilimaussaq complex is an internal rock layer that is comprised of an extremely unusual rock-type call lujavrite. The uppermost sections of lujavrite are strongly enriched in rare earth elements, uranium and zinc, amongst other metals. In the uppermost lujavrite sections, REE concentrations can exceed 1.5%, and U3O8 can exceed 400 ppm. With increasing depth, grades of REEs and uranium drop to sub-economic levels. The thickness of the mineralized sections can exceed 250m in dome-like structural culminations, and such areas can persist over several square km’s. The mineralized lujavrite sections are mostly preserved in the northern half of the Ilimaussaq complex. A world-class multi-element resource has been established at Kvanefjeld, and substantial new satellite deposits have recently been confirmed at Zones 2 and 3. Collectively, these deposits form the resource base of the worlds “specialty metals mega project”.

In the southern half of the Ilimaussaq complex, glacial processes have eroded much of the high-grade lujavrite, leaving sub-economic material. The southernmost part of the complex exposes a basal rock-type known as kakortokite that contains low-grade zirconium resources.

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…

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…

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 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…
