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][2] 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.[3]
Geology
[edit]The Kvanefjeld site is part of the Ilimaussaq intrusive complex.[4] Rare earths and uranium are typically concentrated in lujavrite.[5]
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.[6]
Exploration
[edit]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.[7] 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.[8]
A 2010 relaxation of regulations by the government of Greenland opened up the possibility of large-scale mining.[9] A mining licence application to the Greenland government was submitted in 2015[10] for an open-pit mine.[11][12]
In 2017, the major shareholder of GME was Chinese mining firm Shenghe Resources.[10]
The mine became a significant issue in the 2021 Greenlandic general election, with the new governing coalition, Inuit Ataqatigiit and Naleraq, running on a platform opposing uranium mining.[13] The subsequent ban on uranium mining effectively blocked development of the mine.[14]

the Kvanefjeld mine has its booster in Ib Laursen, the operations manager who has become the public face of the project. A Dane who has lived in Narsaq for over a decade, Laursen is promising 2,000 jobs during the construction of the mine and a new harbour, and a further 800 permanent jobs (300 for locals) over the next three decades.
