December 11, 2025 — U.S.-led plans to mine the deep seabed have gained momentum since President Donald Trump signed an executive order that called for the industry’s rapid formation to bolster U.S. national security. One recent development emerged in November, when U.S. agency Bureau of Ocean Energy Management (BOEM) signaled its intent to open offshore areas of the Commonwealth of the Northern Mariana Islands (CNMI) — an area known to harbor mineral-rich seamounts, hydrothermal vents and abyssal plains — to deep-sea mineral exploration and development.
On Nov. 12, BOEM issued a request for information, or RFI, which indicated its interest in offering mineral rights to companies through lease agreements along the CNMI’s outer continental shelf, a process that could eventually allow commercial mining to proceed on CNMI’s deep seabed. The publication of the RFI included the opening of a 30-day public comment period.
Yet several government officials in both the CNMI and the neighboring island nation of Guam — both of which are U.S. territories that could be directly affected by deep-sea mining in the region — have raised concerns about the brief window they’ve been given to respond to BOEM’s proposal. Some local residents are also pushing back against the proposal, arguing that deep-sea mining would irreversibly damage the marine environment, while disregarding the community’s deep cultural connection to the ocean. If seabed mining does go ahead in the region, critics say it would become another form of colonial exploitation in a region already heavily used by the United States for commercial and military purposes, at the expense of local communities.
