Billions of potato-sized mineral formations have been quietly building for millions of years somewhere on the Pacific Ocean’s abyssal floor, about 4,000 meters below the surface where no sunlight has ever reached. They have never been touched commercially. This is going to change, and an increasing number of environmental organizations are working quickly—possibly too late—to prevent it.
The Metals Company, a Canadian company that operates through its American subsidiary TMC USA, has filed two permit applications. Environment America, Environmental Action, and several affiliated organizations have been urging the public to flood NOAA with comments opposing these applications. The Clarion-Clipperton Zone, a huge area of Pacific seafloor between Hawaii and Mexico that covers about 4.5 million square kilometers, is the target of the applications. It’s among the planet’s least explored habitats. It may contain up to 5,000 species that have not yet received official identification, according to scientific estimates.
This is a strong environmental argument against mining. Massive sediment plumes that could drift thousands of kilometers would be dislodged by deep-sea mining operations, suffocating filter-feeding organisms and upsetting food chains that scientists are just starting to map. These waters are vital to sperm whales, which are already classified as endangered. Underwater mining equipment’s low-frequency acoustic blasting would travel incredibly far, disrupting whale communication in ways that are hard to simulate and most likely impossible to undo.
As this develops, it seems as though the environmental opposition, as sincere and well-researched as it is, is engaged in a conflict that the regulatory calendar has already passed. TMC USA’s combined application for a commercial recovery permit and an exploration license was found to be fully compliant by NOAA in late April 2026. A second application, encompassing 122,000 square kilometers of seafloor, was formally certified by the end of May and moved into the regulatory review process. A mining license is not granted by either of these rulings. However, they convey direction.
The Metals Company’s financial situation is what makes this so difficult. TMC’s own pre-feasibility study had significant flaws, according to an independent analysis commissioned by Greenpeace International, Deep Sea Mining Campaign, and Mining Watch Canada. According to the report, which was written by an expert in assessing the environmental effects of mining, the company’s verified mineral reserves could only support operations for eight years, and even then, there would be no profit.
TMC added 113 million wet metric tonnes of speculative resources that fall short of conventional economic thresholds in order to make its figures appear feasible. It appears that manganese silicate processing markets, which do not yet exist at any commercial scale, account for nearly one-third of the projected revenue. The company has not addressed the content of those findings in a public manner.
It’s difficult to ignore the irony. According to some reliable independent accounts, a project that is being expedited on the grounds of critical mineral supply and national energy security may not even be profitable on its own terms. However, the permitting procedure proceeds. Once created, regulatory momentum usually carries its own weight.
A distinct political tone was established earlier in 2025 when the Trump administration issued an executive order directing agencies to expedite domestic critical mineral production. Applications for NOAA certification are a reflection of a policy environment that considers ocean floor resources to be fair game, regardless of international frameworks. This is not an accident of bureaucracy. The International Seabed Authority, which is in charge of regulating mining in international waters, recently wrapped up another meeting without passing any legally binding regulations. Businesses like TMC have been waiting for that gap.
Campaigns for public comment are important. Sometimes they really do. However, there is a difference between making noise about opposition and actually stopping a permitting process that has this much institutional and political support. There may still be protection for the Clarion-Clipperton Zone. Simply put, the mechanism that saves it is probably not the petition forms that are being filled out today.
