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. 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.
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).
The mineral deposit was first discovered in the 1950s. Much of the historical process development focused on uranium extraction. In 1983, the Danish government decided not to pursue the option of nuclear power, and work programs on Kvanefjeld ceased.
In 2017 the major shareholder of GME was Shenghe Resources Holding Co. Ltd, listed on the Shanghai Stock Exchange.
