Greenland rare earth deposits include two of the world’s largest known undeveloped REE accumulations, yet not a single tonne of rare earth oxide has been produced commercially from the island. Legal conflict, a uranium ban, and infrastructure constraints have kept both primary projects in limbo — even as US strategic interest and EU supply chain policy have elevated Greenland’s resource base to the centre of global critical minerals competition.
Greenland’s Rare Earth Deposits
Greenland’s REE geology is concentrated in the southern Gardar Province, an alkaline igneous complex that hosts exceptional rare earth grades and tonnages. The Geological Survey of Denmark and Greenland (GEUS) maintains the primary resource mapping authority for Greenlandic mineral deposits and has confirmed multiple REE-bearing formations across the island’s southern coast.
Two projects dominate the commercial landscape: Kvanefjeld and Tanbreez. Both rank among the largest undeveloped REE resources outside China by total oxide equivalent. Neither is in production, and neither has a confirmed path to a mining permit.
| Project | Operator | Location | Key Minerals | Status |
|---|---|---|---|---|
| Kvanefjeld (Kuannersuit) | Energy Transition Minerals (ASX: ETM) | Near Narsaq, southern Greenland | REE, uranium, zinc | Halted — uranium ban; litigation active |
| Tanbreez (Kringlerne) | Critical Metals Corp | Kringlerne, southern Greenland | REE (27%+ HREE), zirconium, niobium | Exploitation licence held; production targeted 2028 |
Kvanefjeld (Kuannersuit)
Kvanefjeld holds an estimated resource of approximately 1 billion tonnes at around 1.4% total rare earth oxide equivalent, placing it among the three largest known land-based REE deposits globally. The Ilimaussaq Complex that hosts the deposit contains concentrations of neodymium and dysprosium critical for permanent magnet applications — precisely the elements Western supply chains most urgently need to diversify away from Chinese sources.
The project has been commercially stalled since 2021, when Greenland’s parliament (Inatsisartut) passed legislation banning mining in areas where uranium concentration exceeds 100 parts per million. Kvanefjeld’s ore body contains uranium at 250–350 ppm as a co-product — well above the threshold. The then-developer, Greenland Minerals (now renamed Energy Transition Minerals, ASX: ETM), launched international arbitration proceedings in March 2022, seeking a confirmed exploitation licence or, alternatively, USD 7.5 billion in damages.
In October 2025, the arbitration tribunal issued a significant jurisdictional ruling: the question of whether ETM has any right to an exploitation licence is not arbitrable and must be determined by Greenland’s own courts. Denmark was removed as a party to the arbitration entirely. A residual damages claim may still proceed by arbitration, but only after the Greenlandic courts rule on the licence question. ETM has filed parallel lawsuits in both the Greenland High Court and the Copenhagen City Court. The Greenlandic government’s uranium ban remains in force — upheld by the coalition government formed after March 2025 elections. As of mid-2026, the project has no production pathway and no confirmed timeline for resolution.
Tanbreez
The Tanbreez deposit at Kringlerne, now held by Critical Metals Corp, is the more commercially viable near-term prospect in Greenland’s greenland rare earth pipeline. The deposit is estimated to contain over 4 million tonnes of rare earth oxides, with a notable characteristic that sets it apart from Kvanefjeld: the ore is eudialyte-hosted, meaning it contains no uranium or thorium above background levels. That distinction matters enormously in the current Greenlandic regulatory environment — Tanbreez is not subject to the uranium ban that has paralysed Kvanefjeld.
The deposit contains over 27% heavy rare earth elements (HREEs) by proportion, a figure significantly above the HREE content of most major global REE projects. Dysprosium and terbium — the two most supply-constrained HREEs — are both present. In October 2024, Critical Metals Corp secured an extension on its exploitation licence, with requirements to submit mining and closure plans by end of 2025 and provide financial guarantees by June 2026. The company has targeted the commencement of mining operations by end of 2028 — this is a stated target, not a confirmed date, and is subject to permitting, financing, and infrastructure conditions.
European and South Korean strategic investors have expressed interest in Tanbreez given its HREE profile and its position outside Chinese supply chains. No binding offtake or financing agreement has been publicly confirmed.
Why Greenland Rare Earth Matters Geopolitically
Greenland’s strategic significance in global rare earth supply has intensified sharply since 2024. The Trump administration, returning to office in January 2025, has repeatedly raised the possibility of US acquisition or formal strategic control of Greenland, citing Arctic security and critical minerals access. While Denmark and the Greenlandic government have rejected any suggestion of sovereignty transfer, the US pressure has focused international attention on the island’s resource base in a way that few prior diplomatic interventions have achieved.
The European Union has taken a parallel track. Greenland signed a strategic partnership agreement with the EU in 2023, and the island’s mineral deposits — particularly its REE projects — have been flagged as priority supply sources under the EU Critical Raw Materials Act (CRMA). The CRMA targets a minimum of 10% of EU annual consumption to be sourced from domestic extraction by 2030, with 40% from EU-based processing — Greenlandic supply is a key plank of the diversification strategy given that EU domestic production is negligible.
China has been explicitly excluded from Greenlandic strategic infrastructure. A 2019 decision blocked Chinese state-linked companies from tendering on a Greenland airport project, establishing a precedent that has shaped subsequent investment screening. No Chinese-linked entity currently holds a significant stake in either Kvanefjeld or Tanbreez.
The combination of US pressure, EU partnership, and Chinese exclusion makes Greenland’s greenland rare earth assets among the most geopolitically scrutinised undeveloped mineral resources on the planet. Whether that scrutiny translates into capital and permits is a separate question — and the answer, for now, remains uncertain.

Greenland Rare Earth — Governance and Development Challenges
Greenland is an autonomous territory within the Kingdom of Denmark. Since 2009, the Greenlandic government (Naalakkersuisut) has held sole authority over natural resource management, including mining permit issuance. Copenhagen has no formal role in approving or rejecting mining licences — a jurisdictional point that the October 2025 arbitration ruling reinforced when it removed Denmark as a party to the ETM case entirely.
The 2021 uranium legislation is the decisive regulatory constraint for any REE project where uranium is a co-product. The law was passed with a 37-vote parliamentary majority and reflects both community opposition — particularly from fishing communities near Narsaq who depend on clean marine environments for export revenues — and a broader Greenlandic political shift toward environmental and cultural preservation over resource extraction. Three successive governments have maintained the ban.
Infrastructure poses a separate, durable challenge. Greenland’s population is approximately 57,000, concentrated in small coastal settlements with no road connections between communities. There is no heavy industrial infrastructure, limited grid power, and no processing capacity for rare earth concentrates. Any producing REE mine would require purpose-built port facilities, power generation, and concentrate export logistics. Development timelines for greenland rare earth projects are measured in decades, not years, even in the absence of regulatory obstacles.
Greenland sits within the broader Arctic REE geography that also encompasses significant Norwegian discoveries. For context on the regional supply picture, see our coverage of Norway’s rare earth sector.
Greenland Rare Earth Outlook
The two-project picture facing investors is sharply asymmetric. Tanbreez has a valid exploitation licence, a 2028 production target, and an operator with active financing requirements in place — it is the only Greenlandic REE project with a plausible near-term development path, and even that path carries material execution risk. Kvanefjeld is in multi-jurisdictional litigation with no resolution timeline and a uranium ban that three consecutive governments have declined to reverse.
For Greenland’s greenland rare earth sector to realise its potential, several conditions must align: a Tanbreez financing close and binding offtake agreements; infrastructure investment at Kringlerne; and, separately, a Kvanefjeld legal resolution that either confirms ETM’s claim or establishes a compensated end to the project. None of these are imminent. The geopolitical attention on Greenland — from Washington and Brussels alike — has not yet converted into the capital commitments or regulatory clarity that would move either project toward production.
Investors tracking greenland rare earth exposure should monitor: the Greenlandic High Court’s ruling on ETM’s licence claim (no timeline confirmed); Critical Metals Corp’s June 2026 financial guarantee deadline for Tanbreez; and any formal US-Greenland bilateral resource agreement, which would represent a step-change in the investment environment.

What rare earth deposits does Greenland have?
Greenland’s two primary rare earth deposits are Kvanefjeld (Kuannersuit) in southern Greenland, one of the world’s largest known REE accumulations at approximately 1 billion tonnes, and Tanbreez at Kringlerne, estimated at over 4 million tonnes of rare earth oxides. Both remain undeveloped. The Geological Survey of Denmark and Greenland (GEUS) maps additional REE-bearing geology across the island’s southern Gardar Province.
Why is Greenland rare earth mining politically controversial?
Greenland’s parliament banned mining in areas where uranium concentration exceeds 100 parts per million in 2021. The Kvanefjeld deposit — one of the world’s largest undeveloped REE projects — contains uranium at 250–350 ppm as a co-product, placing it directly within the ban. Three successive Greenlandic governments have maintained the legislation, and the project operator, Energy Transition Minerals (ASX: ETM), is pursuing multi-jurisdictional litigation against the governments of Greenland and Denmark. Local fishing communities near Narsaq have also strongly opposed the project on environmental grounds.
What is the Tanbreez rare earth project in Greenland?
Tanbreez, held by Critical Metals Corp, is located at Kringlerne in southern Greenland and is estimated to contain over 4 million tonnes of rare earth oxides. Critically, it is hosted in eudialyte rock, which contains no uranium or thorium above background levels — meaning it is not subject to Greenland’s uranium mining ban. The deposit contains over 27% heavy rare earth elements (HREEs), including dysprosium. Critical Metals Corp holds an exploitation licence and has targeted mining operations beginning by end of 2028, subject to financing and permitting.
Why is the US interested in Greenland’s rare earth resources?
The Trump administration, returning to power in January 2025, has cited Arctic security and critical minerals access as justifications for its stated interest in Greenland. Greenland’s REE deposits — particularly Tanbreez, which sits outside Chinese supply chains and is not subject to China’s export controls — represent a potential source of heavy rare earths for US defence and clean technology supply chains. The US has no domestic dysprosium or terbium production and is heavily dependent on Chinese processing capacity.
When could Greenland rare earth mining begin?
Critical Metals Corp has targeted mining operations at Tanbreez by end of 2028 — this is an operator target, not a confirmed date, and depends on financing completion, infrastructure development, and regulatory compliance. Kvanefjeld has no production timeline: the project is in active litigation and has no exploitation licence. No greenland rare earth project has yet reached the construction stage, and development timelines for Arctic mining projects typically extend well beyond initial targets.
