- Greenland has ~1.5M metric tons of rare earth reserves but no commercial-scale production, making it a strategic prize despite its small population and harsh geography.
- The U.S. and allies are backing projects like Tanbreez (and the contested Kvanefjeld) and blocking Chinese takeovers to diversify supply chains away from China.
- The binding constraint is midstream processing—refining and separation—where China controls about 90% of capacity, so raw ore access alone doesn’t secure supply.
- Remote infrastructure, high costs, and environmental/regulatory opposition mean turning Greenland’s resources (and data-center appeal) into resilient capacity will take years of coordinated investment.

The article emphasizes Greenland’s strategic unsettledness: despite its tiny population (≈ 57,000), remote location, and low startup density, its geopolitical appeal has re-emerged via its vast rare earth, critical mineral, and data center potential [Primary]. As global supply chains around AI, defense, and green tech intensify demand for specific minerals like neodymium, dysprosium and terbium, Greenland’s untapped reserves become strategically valuable especially against the backdrop of China’s dominance over both mining and processing.
Recent evidence reinforces this: China currently handles approximately 70 % of global REE mining but close to 90 % of refining and separation work; for many heavy REEs essential for defense applications, that share may be even higher. This asymmetry makes ownership of raw reserves insufficient without downstream processing, specialized labor, energy infrastructure, and regulatory certainty—areas where Western nations currently lag far behind.
Projects like Tanbreez (by Critical Metals Corp.) illustrate efforts to build non-Chinese supply lines. The Tanbreez project is estimated to produce about 85,000 metric tons annually of REE concentrate at full scale and has already secured a 10-year offtake agreement with U.S. government-funded facility Ucore Rare Metals to supply up to 10,000 metric tons/year [0news12]. Additionally, the U.S., Denmark, and Greenland have acted to block Chinese acquisition of Greenlandic rare earth deposits to ensure control by Western entities.
However, the challenges are steep. Greenland’s deposits are among world’s best in terms of geological abundance—projects like Kvanefjeld and Tanbreez rank favorably in ore grades compared to many global upper tier deposits. But they remain in feasibility or pre-permitting phases; none is yet fully operational at scale. Transport, energy generation (often hydro or imported fossil fuels), harsh climate, and regulatory & environmental pushback (esp. indigenous rights, fishing/sheep farming) all significantly increase up-front capital risk, Opex burdens, and timelines[0news13].
In the data center space, Greenland offers some key operational advantages—low ambient temperatures reduce cooling costs, large low-density landmass reduces NIMBY and siting friction. But such projects also face infrastructure constraints: grid reliability, power generation, network connectivity, and maintenance challenges in remote/hard climates [Primary]. Even with these advantages, scaling data center capacity will need coordinated investment, policy incentives, and alignment with environmental/social expectations.
From a strategic perspective, Greenland offers a hybrid of resource endowment and geopolitical positioning. The U.S. and EU view it as a partner for reshoring critical mineral supply chains and reducing exposure to export curbs and regulatory weaponization by China. But realizing that vision requires bridging enormous gaps: setting up midstream processing (perhaps in Greenland, U.S., or EU); aligning investment flows; securing local and indigenous consent; building regulatory and logistic frameworks; ensuring environmental protections; and confronting climate and access constraints.
Supporting Notes
- Greenland holds around 1.5 million metric tons of reserves of REEs, placing it among the world’s top8 for rare earth reserves.
- Greenland has two major focused deposits: Kvanefjeld with high REE ore grade (~ 1.43 %), and Tanbreez projected to produce ~ 85,000 metric tons annually of REE concentrate once fully operational[0news12].
- China controls approximately 70 %–79 % of global REE mining output and about 90 % of the world’s processing/separation/refinement capacity.
- The U.S. imports ~80 % of the rare earths it uses from China; for certain heavy rare earths and military-grade elements, reliance is near-total, upwards of 99 % for refining of some elements like dysprosium and samarium.
- Only one rare earth mine operates in the U.S.—Mountain Pass—although historically its output was mostly shipped to China for processing until recently.
- There are currently no REE mines operational in the European Union; Kvanefjeld has completed feasibility/planning and is in permitting, but remains un-operational.
- Critical Metals signed a 10-year supply agreement to deliver up to 10,000 metric tons/year from Tanbreez to the U.S. facility in Louisiana, which aims to start with 2,000 tpa in 2026 and scale to 7,500 tpa by 2028 [0news12].
- Greenland’s harsh Arctic climate, limited infrastructure (e.g. ports, roads, power), extreme cold (below −40°F), and only ~20 % of island ice-free pose operational challenges[0news13].
- Environmental and social concerns (fishing, sheep farming, indigenous livelihoods) alongside regulatory and reputational risks moderate local and global support for mining expansion [0news13].
