US May Explore Joint Rare Earth Mining in Greenland Following New Deal: Rubio

WASHINGTON, Sept 29: The United States could explore opportunities to develop Greenland’s rich deposits of rare earth and other critical minerals in partnership with local authorities, Secretary of State Marco Rubio has said.

Speaking in an interview with Fox News, Rubio indicated that Washington could work with Greenland on mineral development following the signing of a new security agreement involving the United States, Denmark and Greenland.

Asked whether the US could participate in mining rare earth elements on the island, Rubio said such projects could be pursued in partnership with Greenland.

He said mineral extraction had not previously been a priority for Washington, but the conclusion of the latest agreement could create opportunities for investment in the territory.

The comments come after the US, Denmark and Greenland signed an agreement on September 22 aimed at expanding American military activities in Greenland. The accord allows Washington to modernise and expand operations at Pituffik Space Base and establish additional defence areas at Narsarsuaq and Mestersvig.

The agreement also establishes provisions concerning foreign investment in sensitive sectors. Under the pact, investors from countries outside NATO, NATO partner states and the European Union face restrictions on control, significant influence or access to non-public information in particularly sensitive sectors and activities in Greenland, unless the parties agree otherwise.

Greenland has attracted international attention because of its substantial mineral potential. The Geological Survey of Denmark and Greenland (GEUS) says 24 of the 34 raw materials classified as critical by the European Union have been identified on the island. These include resources of importance to modern industrial, energy and technology supply chains.

GEUS has identified several areas with notable deposits of rare earth elements and other critical materials. In South Greenland, the Gardar alkaline province contains known deposits associated with rare earth elements as well as lithium, fluorite, tantalum, niobium, hafnium and zirconium.

The mineral potential has nevertheless not translated into large-scale extraction. Developing deposits in Greenland presents significant practical challenges, including the island’s harsh climate, difficult terrain, limited infrastructure and the remote location of many mineral occurrences.

The exact scale of some resources also remains uncertain. Further exploration and feasibility work would be required before many deposits could be developed commercially.

For Washington, greater access to critical minerals could have economic and strategic significance. Rare earth elements are used in a range of high-technology applications, including electronics, advanced manufacturing and defence-related equipment. Secure access to such materials has become an increasingly important issue for governments seeking to strengthen supply chains.

Rubio’s remarks suggest that mineral development could become an additional area of US-Greenland cooperation following the security agreement. However, his comments point to a potential opportunity rather than the announcement of a specific mining project.

The September 22 agreement primarily concerns defence and security arrangements. It expands US military access and provides for additional defence facilities while reaffirming Greenland’s right to self-determination and Denmark’s sovereignty under the current constitutional arrangement.

The accord also requires US activities to take account of Greenlandic society and culture. Its economic provisions place particular restrictions on investments in sensitive areas, reflecting concerns about foreign influence over strategically important infrastructure and resources.

Any future mining development would therefore involve more than identifying deposits. Projects would need to address environmental considerations, infrastructure requirements, financing, permitting and the interests of Greenlandic authorities and communities.

Greenland’s mineral resources have been the subject of geological assessments for years. GEUS research has identified several major deposits and highlighted the broader potential for additional discoveries, particularly in southern parts of the island.

The Arctic territory’s mineral wealth has gained further attention as countries seek to diversify supplies of materials considered essential to advanced industries. At the same time, the difficult operating environment means that resource potential does not automatically translate into economically viable mining operations.

Rubio’s comments therefore mark a possible new dimension in US engagement with Greenland. Alongside defence cooperation, Washington could seek greater economic involvement in the island’s strategic mineral sector.

For Greenland, potential investment could bring opportunities for infrastructure development and economic activity, while decisions over the exploitation of natural resources remain closely connected to environmental protection, local interests and the territory’s political autonomy.

No specific US-Greenland mining venture, production timeline or investment amount was announced in Rubio’s remarks. Any such project would require further negotiations and assessments before mining activity could begin.

The immediate significance of the comments is that mineral development has emerged as a possible area of cooperation following the new security arrangement, adding an economic dimension to Washington’s growing strategic interest in Greenland.
