Kvanefjeld

Kvanefjeld (or Kuannersuit), in Greenland, is the site of a mineral deposit, which is claimed to be the world's second-largest deposit of rare-earth oxides, and the sixth-largest deposit of uranium.[1] There are also substantial sodium fluoride deposits, and Kvanefjeld is thought to be one of the largest multi-element deposits of its kind in the world.[2]

GeologyEdit

The Kvanefjeld site is part of the Ilimaussaq intrusive complex.[3] Rare earths and uranium are typically concentrated in lujavrite.[4]

Lujavrite, a dark agpaitic nepheline syenite, occurs as an internal layer in the north Ilimaussaq complex. The uppermost sections generally have the highest rare-earth elements, uranium and zinc grades.

Lujavrite is a rare variety of nepheline syenite having amphibole, aegirine pyroxene, nepheline and feldspar. The red spots in the rock are crystals of the rare halide mineral villiaumite (NaF - sodium fluoride).

Kvanefjeld is already known among mineral collectors as a source of fluorescent minerals such as tugtupite and chkalovite.[5]

ExplorationEdit

The mineral deposit was first discovered in the 1950s. Much of the historical process development focused on uranium extraction, including a promotional visit by physicist Niels Bohr to the nearby town of Narsaq in 1957.[6] In 1983, the Danish government decided not to pursue the option of nuclear power, and work programs on Kvanefjeld ceased.

Greenland Minerals and Energy acquired the area in 2007.[7]

A 2010 relaxation of regulations by the government of Greenland opened up the possibility of large-scale mining.[8] A mining licence application to the Greenland government was submitted in 2015[9] for an open-pit mine.[10][11]

In 2017 the major shareholder of GME was Shenghe Resources Holding Co. Ltd, listed on the Shanghai Stock Exchange.[9]
