September 14, 2026 — Conservation and community groups filed a lawsuit Tuesday challenging the Trump administration’s plan to kickstart deep-sea mining off the coasts of the Commonwealth of the Northern Mariana Islands and Guam. The first lawsuit was specific to the Trump administration’s attempt to launch deep-sea mining off the coast of American Samoa.
Meanwhile, CNMI Del. Kimberlyn King-Hinds wants territories to get a 50% cut of revenues from any deep-sea mining leases.
Tuesday’s lawsuit is the second filed by Earthjustice, a nonprofit environmental law organization, on behalf of parties Our Common Wealth 670, PåganWatch, Conservation Council for Hawai’i and Center for Biological Diversity. The first lawsuit was specific to the Trump administration’s attempt to launch deep-sea mining off the coast of American Samoa.
The mining leases were advanced by the Marine Minerals Administration in July and August, first for the seabed of American Samoa and then for the Marianas Islands. A lease sale is planned for Dec. 16 for the Marianas and for American Samoa in November.
