Why does the US want Greenland?

Small beside China. Enormous beside a population of 57,000. The same deposits tell two very different stories about what America wants, and what Greenland stands to gain.

Research cut-off: 28 September 2026. Reserve, production and population dates are identified separately.

Put Greenland beside China on a chart of rare-earth reserves and it looks small. The US Geological Survey reports 1.5 million tonnes of rare-earth-oxide equivalent for Greenland, against China’s 44 million.

Then you change the denominator.

Greenland’s reported rare-earth reserves work out at roughly 26 tonnes of oxide equivalent for every resident. Australia’s come to about a quarter of a tonne. China’s, about 31 kilograms. Those are geological quantities, not anyone’s personal fortune. But they explain why a deposit that looks modest from Washington can look extraordinary from Nuuk. ^[1]

That is the tension running through Greenland’s mineral story. America is looking for another source of materials its industries need. Greenland has to decide how much mining it wants, on whose terms, and how much of the resulting business will stay at home.

Two ways to measure an opportunity

EarthRarest’s rare-earth mining race puts Greenland in useful company. China already has mines, refineries and magnet factories. Australia has an established mining industry. Greenland has promising projects trying to reach commercial production.

Greenland accounts for less than 2% of the USGS world reserve total, which exceeds 75 million tonnes. Australia alone reports 6.3 million tonnes. And while China mined an estimated 270,000 tonnes in 2025, Greenland had no reported rare-earth production. It could add another source of supply without becoming anything like the largest one.

For a country with 56,945 residents in July 2026, the calculation is different. One successful mine could matter a great deal to employment, public revenue and the range of businesses the economy can support. A small population also means a limited pool of local workers and suppliers. The national benefit depends on who gets the contracts, who does the work and what the government collects.

The population comparison makes the stakes easier to see. It does nothing to make the ore cheaper to process. ^[1]

What Washington has actually said

“we need Greenland for national security. Not for minerals.”

— Donald Trump, 22 December 2025 ^[2]

Greenland’s position between North America and the Arctic gives that statement substance. At Pituffik Space Base, American radar helps detect ballistic missiles and track objects in orbit. The US already operates there under defence agreements. The location has military value whether or not another tonne of ore ever leaves the island.

Trump’s team has also made the mineral argument openly.

“Yes, the access to the minerals on Greenland are critically important.”

— Marco Rubio, Senate confirmation hearing, 15 January 2025 ^[2]

Both interests can exist at once. The transcripts support a defence case and a resource case; they do not tell us how Trump privately weighs one against the other. The mineral case is easier to assess when we stop bundling every useful element under “rare earths”.

Where the deposits are found

01 / Actual rare earths

The minerals are real. The headlines often mix up the quantities.

Rare earths are a recognised group of 17 elements. Greenland has them. The interesting argument is about which ones can be recovered, in what amounts and at what cost.

Neodymium and praseodymium are central to powerful permanent magnets; dysprosium and terbium can help those magnets tolerate heat. A deposit’s total rare-earth tonnage tells us much less than the mix of elements and the cost of separating them. ^[3]

Three terms keep the numbers straight. A resource estimates mineralised material with prospects for eventual extraction. A reserve is the economically mineable portion established through the required technical work and assumptions. Production is what a mine actually delivers. National tables and individual project estimates also have different dates and reporting bases. They cannot simply be added together.

Tanbreez: the chemistry behind the giant number

Tanbreez, in southern Greenland, is the project behind many of the most spectacular claims. Its much repeated 4.7-billion-tonne figure describes a conceptual mass of mineralised rock. The company's initial reported resource was far smaller: 44.87 million tonnes of rock grading 0.38% total rare-earth oxides, or approximately 170,000 tonnes of contained oxides. Its April 2026 technical report stated that no mineral reserves had been established. ^[4]

The rare earths occur in eudialyte-bearing rock, alongside zirconium and other elements. The heavy-rare-earth share helps explain the interest in Tanbreez, although that category includes yttrium. Reading “heavy rare earths” as if every tonne were dysprosium or terbium would badly misprice the material.

ILÍMAUSSAQ / REAL SPECIMEN

What the mineral-bearing rock actually looks like

The reddish grains are eudialyte. The black mineral is arfvedsonite; pale minerals make up much of the rock around them.

The useful elements sit within minerals. Recovering them means breaking down and separating this material.

Mineral identification follows the photographer’s specimen description. The photograph shows a cut sample, rather than a weathered outcrop.

The project has a 30-year exploitation licence, issued in 2020. In May 2026, REalloys signed an agreement for 15% of planned Phase 1 production. That gives the deposit a prospective customer as well as a geological story. Delivery still requires a functioning mine and processing route. ^[4]

Kuannersuit: a large deposit with a political limit

Kuannersuit, also known as Kvanefjeld, shows why tonnage alone is a poor guide to a project’s future. Its historical estimate lists 1.01 billion tonnes of rock containing 11.14 million tonnes of total rare-earth oxides, including yttrium. More than half the rock tonnage was in the lower-confidence inferred category. This is a resource estimate, not another national reserve figure. ^[5]

The deposit also contains uranium. Greenland’s 2021 law prohibits uranium exploration and exploitation. It also prohibits projects targeting other minerals when their average elemental uranium content exceeds 100 parts per million. An exploitation application was refused in 2023; the company reported refusal of an exploration-licence extension in June 2026.

Here, the issue goes beyond whether the chemistry works. Greenland has made a political choice about what it is prepared to mine. A larger rare-earth estimate does not resolve that choice. ^[5]

02 / Strategic metals, by our definition

A narrower category, with much patchier evidence

EarthRarest uses strategic metals for eight specialist materials: antimony, bismuth, gallium, germanium, hafnium, indium, rhenium and tellurium. This is our editorial category. Government lists of critical or strategic raw materials use different definitions.

Hafnium has the clearest connection to a prominent Greenland project. GEUS identifies it with the zirconium-bearing mineralisation at Kringlerne, the deposit developed as Tanbreez. That makes it a possible additional product to investigate. Commercial recovery would require its own technical and economic case. Our hafnium guide explains why its supply is so closely tied to zirconium processing.

Elsewhere, the evidence gets thinner. GEUS records antimony at North Margeries Dal and a historical gallium estimate at Skaergaard, but these are not modern reserve statements. Germanium and bismuth appear in the geological record without a quantified national resource in the material reviewed here. ^[6]

Evidence for the remaining metals is uneven. A 2016 GEUS assessment recorded rhenium in a quartz-vein sample; 2023 research described tellurium-bearing minerals in the Black Angel district. The older GEUS assessment reported no known indium occurrences at the time, while identifying favourable geology. That dated finding cannot establish absence today. ^[6]

This is a plausible exploration and by-product story. The evidence does not yet support describing Greenland as an established supplier of EarthRarest’s eight strategic metals. In several cases, the commercial question is whether recovering a small additional product would pay once a mine for something else already exists.

03 / Supplementary critical materials

“Supplementary” describes their place in this article. Some of these materials have a stronger development case than the metals that receive the most attention.

Graphite: the factory is a separate investment

Graphite is carbon, not a metal, and it deserves a prominent place in this story. GreenRoc’s Amitsoq project has a reported resource of 23.05 million tonnes at 20.41% graphitic carbon, containing 4.71 million tonnes of graphite. It received a 30-year exploitation licence in December 2025. ^[7]

The grade is striking. The next part of the business is less visible: making material that a battery manufacturer will accept. Particle size, shape, purity and treatment all matter. GreenRoc has pursued that work separately, including a pilot plant in Denmark. Its initial pilot work used third-party graphite, so it should be read as progress on a processing method rather than output from a Greenland mine.

The capital estimates reveal how much business sits beyond the pit.

Those historical studies put the commercial anode-material plant at roughly 2.6 times the cost of the mine and its primary processing facilities. They are separate estimates from different years, not a current combined construction budget. Even so, they show where much of the investment could go. ^[7]

For Greenland, a mine exporting concentrate and an industry selling finished battery material would be very different economic achievements. The first can still create value. The second requires another set of skills, customers, energy arrangements and financing decisions.

Molybdenum: a 23-kilometre conveyor tells the story

Malmbjerg is a substantial molybdenum project in eastern Greenland. Greenland Resources reports 245 million tonnes of proven and probable reserves grading 0.176% molybdenum disulphide, containing 571 million pounds of molybdenum metal. Molybdenum earns its place in critical-material discussions through demanding steel and alloy applications, although it sits outside EarthRarest’s eight-metal category. ^[8]

The construction plan includes a 23-kilometre conveyor, glacier access roads, a powerhouse and fuel storage. The mine has to build much of its supporting infrastructure before making its first commercial shipment.

In August 2026, the Nordic Investment Bank issued a non-binding letter of interest for up to US$120 million of financing. The bank’s interest is conditional; the financing is still being assembled. ^[8]

Titanium, nickel, cobalt and the next wave

Greenland’s wider inventory includes titanium, nickel, cobalt, niobium, tantalum, zirconium, tungsten and vanadium. Their projects and occurrences occupy very different stages of development.

Dundas illustrates the difficulty. The ilmenite project reported a 117-million-tonne resource grading 6.1% ilmenite, a titanium-bearing mineral, but its owner subsequently recorded a £25.3 million impairment. At Disko-Nuussuaq, drilling for a nickel-copper-cobalt and platinum-group-metal opportunity began in July 2026. One is a reminder that a project’s prospects can deteriorate; the other is still testing the geology. ^[9]

04 / Base metals, precious metals and industrial minerals

Gold is already leaving the ground

The material that makes the grandest geopolitical headline is not necessarily the one paying wages today.

Amaroq reported 8,985 ounces of gold production at Nalunaq in the first half of 2026. Its operator reported about 90% processing recovery in July, a useful measure of a plant becoming better at recovering metal from the ore it treats. Lumina’s anorthosite operation supplies an industrial mineral rather than a rare or precious metal. These businesses give Greenland practical experience of extraction, processing and exports. ^[10]

Copper, zinc, lead and platinum-group metals broaden the longer-term possibilities. But old project lists need pruning. Citronen’s developer announced in December 2025 that it had lodged notice to relinquish the zinc-lead project’s licence and would wind up local operations. Counting every historical project as an active candidate makes Greenland look further along than it is. ^[9]

These less glamorous materials belong in the article because Greenland’s economic interest is broader than America’s search for vulnerable inputs. A gold mine, an industrial-mineral export business and a rare-earth project can each contribute in different ways. Their value to local people cannot be ranked simply by how often a metal appears in a Washington speech.

The part Trump came closest to explaining

“No such thing as rare earth. There’s rare processing.”

— Donald Trump, Davos, 21 January 2026 ^[2]

Taken literally, the first sentence is wrong: rare earths exist as a defined group of elements. In context, Trump was talking about their abundance and arguing that processing was the difficulty. That second point goes to the heart of the American supply problem.

A mine produces feedstock. Separation plants isolate the useful elements. Further operations make metals, alloys and components to a buyer’s specification. Owning or influencing the territory at the start of that chain would not, by itself, supply the factories at the end.

The IEA’s comparable 2024 figures put China at 60% of magnet rare-earth mining, 91% of refining and 94% of sintered permanent-magnet production. Its newer update places the leading refiner’s 2025 share at 85%; the chart keeps all three stages in 2024 rather than mixing years. Either way, the industrial concentration remains formidable. ^[3]

Tanbreez makes the connection concrete. In September 2026, its developer announced results showing more than 99% dissolution of eudialyte concentrate and a proposed Romanian refinery cost of US$1.85 billion, with a ±25% range. Dissolving the feed successfully is one step; the announcement also described further work on product purity. It was not evidence of a complete commercial plant recovering 99% of saleable material. ^[4]

Romania in the rare-earth plan. Denmark in the graphite plan. These locations help explain the real competition: where the processing will happen, who will finance it and which customers will receive the output. Greenlandic geology could support an allied supply chain spread across several countries.

What would control actually buy?

American influence could help determine which companies invest, which lenders support them and where the material is sold. That gives access to minerals strategic value well before a mine opens. It does not require every project to succeed; a credible alternative supplier can be useful in a market with few substitutes.

There are already ways to pursue access through commercial contracts and agreements. The Arctic agreement signed by the United States, Denmark and Greenland on 22 September 2026 addresses defence and investment screening, including sensitive resource activity. It retains sovereignty; entry into force depends on the required notifications. It should not be read as a transfer of Greenland or blanket American ownership of its minerals. ^[11]

The harder local bargain is about the shape of the industry. If concentrate goes abroad for refining, Greenland receives the benefits associated with extraction while much of the subsequent activity takes place elsewhere. Keeping more processing at home could retain additional work, but only if energy, infrastructure, staffing and costs make that choice viable.

Greenland’s own 2026 study of sustainable energy for mining points to practical combinations of power sources, rather than one easy answer for every site. Most known deposits are already in ice-free areas. A retreating ice sheet is no substitute for ports, power and a workable mine plan. ^[12]

Ice inland, fjords at the coast

A mine can be small for America and large for Greenland

The strongest mineral case for American interest is selective. A particular rare-earth mix, a graphite product or a dependable molybdenum supplier could help reduce exposure in a specific industrial chain. Greenland does not need to replace China across the periodic table to be useful.

For Greenland, success can be measured more locally: a mine that operates for years, trains residents, buys from local firms and leaves public revenue behind. A huge resource estimate is only the beginning of that calculation. The location of the refinery, the terms of the contract and the cost of closing the mine belong in it too.

For the individual projects and their place in the wider race, continue with Greenland’s rare-earth projects, permits and processing plans.
