“The Bureau of Ocean Energy Management (BOEM) is initiating the first steps that could potentially lead to a lease sale for minerals on the Outer Continental Shelf (OCS) offshore Alaska by publishing this request for information and interest (RFI).”
“The objective of this rule is to provide the option for a consolidated application streamlining the process for qualified applicants.”
Reflecting on advances in environmental science, seafloor mapping, and offshore mineral-collection technologies, the revised rule allows qualified companies that gather the necessary site information to proceed to the collection phase. Deepsea mining is now more closely aligned with offshore oil and gas in that companies acquiring licenses are able to proceed to production after regulatory approvals.
The preamble nicely summarizes the opposition to the rule for environmental and jurisdictional reasons:
“General opposition to deep seabed mining was expressed for a variety of stated reasons, including, but not limited to the following assertions: effects on the environment; effects on seabed habitat and to marine species including undiscovered species especially in the Clarion-Clipperton Fracture Zone; harm to cultural resources and Pacific Islander livelihoods and beliefs; inadequate scientific research and information; inadequate resource protection measures and regulations; uncertainties regarding environmental impacts and a nascent industry; significant technical challenges to deep seabed mining; opposition to deep seabed mining from many U.S. states, countries, and global companies; that deep seabed mining is contrary to international agreements and efforts; the need for moratoria; that deep seabed minerals are not needed to meet U.S. demand for critical minerals and domestic sources and recycling of such minerals should be used instead; the U.S. needs to focus on building domestic refineries; using renewable and alternative resources rather than deep-sea minerals; and jeopardizing vital carbon sinks.”
“Commenters stated that acting unilaterally on deep seabed mining undermines the ISA (International Seabed Authority) process, international norms, global stability, and the rule of law, and that it could result in harm to protected areas, such as Areas of Particular Environmental Interest designated by the ISA.”

Odyssey’s primary targets are phosphate, which is now on the critical minerals list, and rare earth element’s titanium and zirconium. This would be a shelf dredging operation, in partnership with Great Lakes Dredge & Dock Company, rather than the deepwater module collection being proposed for the Pacific.
The fact that the sand recovered during the dredging process could be used for beach nourishment should appeal to adjacent coastal communities.

Conceptually, this technologically advanced polymetallic nodules collection system looks great. The big challenge that John Smith sees is with the number of moving parts. The numerous manipulators operating at such depths could be prone to breakdowns which reduce recovery rates and significantly increase operating costs.

An Impossible Metals table (below) understandably favors their methods vs. those employed by deep-sea mining rival The Metals Company. However, both approaches are far preferable, environmentally and socially, to onshore metal mining.
On August 11, 2025, TMC USA received notice of full compliance from the National Oceanic and Atmospheric Administration (NOAA) on its exploration applications, and reconfirmation that TMC USA has priority right over both exploration areas
Both applications entered the certification stage in late July, which we expect to be approximately 100 days
In light of recent U.S. regulatory developments, TMC expects to commence commercial production from the NORI-D Area in the fourth quarter of 2027 if we receive a commercial permit before scaling to an average annual production rate of 10.8 million tonnes of wet nodules per annum (Mtpa) at steady state (2031 through 2043) production, with an expected 18-year life of mine (LOM);
Meanwhile, after missing deadlines in 2020 and 2023, the International Seabed Authority (ISA) again failed to deliver a Mining Code as communicated in their 2023 roadmap during the second part of their 30th session in July 2025. No new roadmap or new target date for adopting the final Mining Code has been agreed. The next ISA meeting is scheduled for March 2026. (Hence the importance of direct permitting through the US/NOAA.)

The proposed rule is attached. Important points:
How can the US issue mining licenses in international waters (controversial)?
“The International Seabed Authority (ISA) regulates deep seabed mining in areas beyond national jurisdiction for countries that are parties to the United Nations Convention on the Law of the Sea (UNCLOS). The United States is a non-party to UNCLOS. Under U.S. law, NOAA may issue licenses and permits to U.S. citizens in areas beyond national jurisdiction under the Deep Seabed Hard Mineral Resources Act (DSHMRA).“
Main objective of the proposed rule (paraphrased):
The deepsea mining industry has gained experience from site specific exploration activities. As a result, later entrants may be able to capitalize on the information gained by previous explorers and lessen the need for further exploration of previously explored areas. In such cases there may be a need for a consolidated licensing process in which permit applicants could meet exploration license requirements to establish priority of right, and permit requirements, simultaneously.
Comment: The proposed rule seems reasonable in that qualified companies that gather the necessary site information would have the right (after NOAA review and approval) to collect the minerals. This would align deepsea mining more closely with offshore oil and gas in that companies acquiring licenses would be able to proceed to production after regulatory approvals.
For those who want to provide input on an American Samoa marine minerals sale, now is your chance. See the attached Request for Information and Interest.
The first step will be the publication of a request for information and Interest in the Federal Register. This notice will seek public input that will help inform BOEM’s assessment of geologic conditions, potential environmental and cultural impacts, and other uses of the area.Â
Impossible Metals has developed an autonomous underwater vehicle (AUV) for selective mineral harvesting. Their novel AUV uses advanced robotics, AI, and a buoyancy engine to hover above the seabed and minimize disruption to the habitat and native biodiversity. Impossible Metals believes this method will have the lowest environmental impact and cost among land and deep-sea mining approaches.
