Mining has had a small impact on the economy of Greenland. Since 2010, governance over the sector has been under the authority of the Naalakkersuisut (Government of Greenland), following self-rule in 2009. Greenland's deposits of critical minerals, such as rare-earth elements used in electric vehicles and wind turbines, as well as nickel and cobalt for battery production, have drawn attention from governments in the United States and Europe, which are seeking to reduce dependence on China and ensure stable supplies for technological and defense needs.
Greenland contains deposits of coal, diamonds, and a range of metals, including silver, nickel, platinum, copper, molybdenum, iron, niobium, tantalum, uranium, and rare-earth elements. However, as of 2011, these deposits were not commercially viable, although Greenland's Bureau of Minerals and Petroleum continued efforts to promote the territory as a destination for mineral exploration.
History Greenland was once part of a larger landmass that included areas of present-day northern Europe and North America. About 500 million years ago, it formed part of a supercontinent situated between Europe and North America. Between roughly 60 and 65 million years ago, this landmass began to rift, a process that led to the opening of the North Atlantic Ocean. As the separation progressed, Greenland moved westward and passed over the Iceland hotspot, where rising magma contributed to the volcanic activity that later formed Iceland. The island now contains geological formations ranging from Precambrian basement rocks to glacial sediments.
European whalers are believed to have been among the first to obtain coal from outcrops on Disko Island, using it as fuel for blubber processing, while in Greenland it was primarily used for domestic heating. In 1777, the Royal Greenland Trading Department sent a German mining specialist to the Umanak colony to assess the feasibility of coal extraction for local use. Small-scale coal extraction on Disko Island followed in 1782, marking the earliest recorded mining activity in Greenland. In 1924, Denmark established a coal mine at Qullissat on Disko Island, which became a major operation staffed largely by Greenlandic workers. The mine was modernized in 1929 and continued operating until its closure in 1972 due to economic factors, after which the settlement was abandoned.
In 1799, cryolite was discovered in Ivittuut,Mindat – the Mineral and Locality Database. "Cryolite". Accessed 5 May 2012. and nearby silver-bearing lead veins were briefly mined by British engineer J.W. Tayler before the low silver content made the operation unprofitable. Danish engineers began extracting cryolite in 1859, and in 1864, the Danish Kriolit Mine og Handels Selskabet received a monopoly on its production.Doody, Richard. The World at War. "GREENLAND 1721 - 1953". Accessed 28 Apr 2012. Early mining operations processed cryolite for its aluminum content and supplied the Pennsylvania Salt Manufacturing Company, which used it to produce caustic soda. The 1884 development of the Hall–Héroult process, which relies on cryolite to extract aluminum from bauxite, increased the mineral's value. During World War II, the Ivittuut mines influenced the American occupation of Greenland, and the United States Navy established the Kangilinnguit naval base, also known as Bluie West Seven, to protect the cryolite quarry. After the war, the Danish company Kryolitselskabet Øresund continued mining cryolite, and revenues from the operation contributed to the founding of Grønlandsfly, now known as Air Greenland. The deposit eventually became uneconomical as synthetic cryolite became widely available. Mining activities ended in the early 1960s, although existing stockpiles continued to be exported. The Ivittuut mine was permanently closed in 1987, ending cryolite shipments from the site.
The first scientific descriptions of rare-earth elements in Greenland were published in 1806 by K. L. Giesecke, who identified arfvedsonite, eudialyte, and sodalite at the Ilimaussaq intrusive complex. Systematic geological surveys from the 1950s included airborne gamma-ray and ground scintillometric investigations, which identified uranium and rare-earth element potential at sites such as Kvanefjeld, with radiometric anomalies detected around 1956 and follow-up drilling carried out in the 1960s and 1970s. International exploration for rare-earth elements grew in the 2000s, particularly after 2007, when exploration licenses were issued for alkaline complexes including Ilimaussaq. By 2015, numerous licenses targeting rare-earth elements covered large areas of southern Greenland.
Comprehensive geological mapping began after the war, and two decades of coastal surveys showed how extensive the work would be. Estimates indicated that the ice-free regions would require approximately 200 map sheets at a 1:100,000 scale, and at the existing pace, the work would take about two centuries. The project shifted to a broader-scale approach, and initial maps of Greenland were completed in the early 2000s.
Kvanefjeld was first recognized in the 1950s, when its uranium potential attracted international interest during the Cold War. Niels Bohr visited nearby Narsaq in 1957 to support early investigations. Exploration ended in 1983 after Denmark decided to discontinue nuclear power. Greenland Minerals and Energy, later renamed Energy Transition Minerals, acquired the area in 2007.
In 1966, Dr. Martin Ghisler of the Geological Survey of Denmark and Greenland identified gem-quality ruby in an exposed rock formation on what later became known as Ruby Island. Exploration efforts relied on local knowledge from residents of the nearby village of Qeqertarsuatsiaat, formerly known as Fiskenæsset. Ruby was identified in association with sapphirine, kornerupine, pargasite, and phlogopite, leading to the confirmation of six ruby deposits in the Fiskenæsset district.Petersen, O.V., and Secher, K., 1993, The minerals of Greenland: Mineralogical Record, v. 24, n. 2, 88 pp. During the 1970s, several Canadian junior mining companies, including Platinomino, Fiscannex, and Valhalla, explored the area for chromite and platinum and attempted to commercialize the ruby occurrences, but these efforts were unsuccessful.Geisler, R.A., 1976, The ruby deposits at Fiskenæsset, Greenland: Canadian Gemmologist, v. 1, n. 2, p. 4. In 1995, Peter Appel of the Geological Survey of Denmark and Greenland published a review examining six ruby deposits in the Fiskenæsset district and concluded that the area needed further exploration. Following these findings, independent geologists Bill Brereton and Bill Anderson consolidated land holdings in the Fiskenæsset area.Anderson, W.J., 1995, Economic geology and exploration potential of the Frederikshab Isblink – Sondre Stromfjord area: Greenland Geological Survey Open File Series 94/18, 30 pp.
Interest in petroleum resources began in the early 1970s following seismic studies around Greenland. The 1973 oil crisis encouraged exploration in an area previously known primarily for its fisheries. In 1975, leases were granted to several major companies, including Mobil, Amoco, Chevron, and Total. Drilling in 1976 and 1977 produced five dry wells. A 1997 study by the Geological Survey of Denmark and Greenland concluded that these wells had been abandoned without a full assessment of their potential. A sixth well drilled in 2000 by Statoil was also dry.
Gold exploration in the area began in the late 1980s, when geologists from the exploration company Carl Nielsen identified gold flakes in coastal gravel at the foot of Kirkespiret mountain. Earlier geological mapping conducted in the 1960s by the Geological Survey of Greenland provided a basis for further work. In 1990, the Greenland exploration company Nunaoil received an exploration license, and its chief geologist believed the idea that the coastal gold originated from primary deposits in the surrounding mountains. In 1992, primary gold was identified nearly above sea level on the slopes of the Kirkespirdalen valley. The mineralization was visible in exposed quartz veins and appeared to extend for roughly . Additional companies later joined the exploration efforts, carrying out the first drilling campaigns, and in 1998, an investigation adit was constructed, allowing the extraction of ore for pilot production and processing. Crew Gold Corporation, a British company, acquired a majority stake in the project in 1999, while Nunaminerals held 17.5 percent. The Nalunaq gold mine, located northeast of Nanortalik in the Ketilidian Orogenic Belt,Nalunaq Gold Mine, information courtesy of the mine owner. was officially opened on 26 August 2004. In November 2007, Crew Gold Corporation acquired full ownership of the mine.
As of 2012, partly due to the retreat of the ice sheet linked to climate change, Greenland was identified as a region with significant untapped mineral resources. Research by GlobalData indicated that substantial mineral deposits were accessible using geological mapping technologies.
A major challenge is the island's limited infrastructure. The CEO of Nunaminerals, which declared bankruptcy in 2015 after 17 years of operation, stated that Greenland projects required the construction of roads, power plants, and other facilities, unlike similar deposits in more developed regions. As of 2025, Greenland had fewer than 100 miles of paved roads.
As of 2025, Lumina was extracting anorthosite, and KoBold, financed by Jeff Bezos, Bill Gates, and other investors, was exploring nickel deposits. Critical Metals Corporation operated a mine in southern Greenland, supported by Cantor Fitzgerald, whose chief executive before 2025 was Howard Lutnick.
Location
Since World War II, Greenland has operated nine mines, of which only one, producing anorthosite, remains active. A gold mine is expected to reach full production later in the year.
Active mining areas include the Maamorilik site, which contains deposits of zinc, iron, lead, and silver,Bureau of Minerals and Petroleum and Kvanefjeld, which contains deposits of rare-earth elements, uranium, and zinc.
Greenland is estimated to hold approximately 1.5 million tonnes of rare earth reserves, although no rare earth mine production was recorded in 2025. Michael Langford, EBC's Market Analyst has noted the disparity between Greenland's mineral potential and its current output.
Proposed mines in Greenland include: The Isua Iron Mine, located northeast of Nuuk, was planned to extract and export high-grade iron ore containing approximately 70 percent iron from the edge of Greenland's ice cap. The Citronen mine, located in Citronen Fjord, is planned to produce lead, zinc, and germanium. The site contains an estimated 100 million tonnes of ore with grades of 2 percent lead and 3 percent zinc. The Motzfeldt mine in Kujalleq is intended for niobium and tantalum extraction. It is one of Greenland's largest niobium reserves, with estimated deposits of 130 million tonnes of ore grading 1 percent niobium and 0.04 percent tantalum. The Qaqqaarsuk deposit in Qeqqata is planned for niobium extraction. It contains an estimated 3.5 million tonnes of ore with a niobium grade of 0.5 percent.QaqqaarsukQaqqaarsuk
Resources
Coal As of 2016, Greenland held an estimated 202 million short tons of proven coal reserves and had no coal imports or exports. This placed Greenland 52nd globally and represented approximately 0.018 percent of the world's total proven coal reserves, estimated at 1,139,471 million short tons. The proven reserves of Greenland exceeded its annual coal consumption, indicating that existing reserves could support consumption for a long amount of time. Gemstones
