TMC USA files deep-seabed mining application for 65,000 km2

Application is the first consolidated exploration license and commercial recovery permit application submitted under NOAA’s new consolidated application and review process—which the Company expects will reduce permitting timelines for companies with completed exploration programs—in line with Executive Order 14285 , ‘Unleashing America’s Critical Offshore Minerals and Resources’ The consolidated application covers areas previously applied over in April 2025 and increases the commercial recovery area from ~25,000 to ~65,000 km 2 , with an estimated resource of 619 million tonnes (Mt) of wet nodules and a potential exploration upside of an additional 200 Mt TMC USA applied under the new consolidated application process because it can demonstrate the scientific, technical and financial capability to pursue commercial recovery activities expeditiously and in accordance with the new rule Supported by newly published, peer-reviewed research drawing on the Company’s test mining and recovery data—which demonstrates that both benthic biodiversity and sediment plume impacts are confined to the directly mined area—TMC USA is confident that its dataset provides a robust, scientifically grounded basis to commence and responsibly scale commercial operations NEW YORK, Jan. 22, 2026 (GLOBE NEWSWIRE) -- TMC the metals company Inc. (Nasdaq: TMC) (“TMC” or the “Company”), a leading developer of the world’s largest resource of critical metals essential to energy, defense, manufacturing and infrastructure, today announced that its U.S. subsidiary, The Metals Company USA LLC (“TMC USA”), has submitted a consolidated application to the National Oceanic and Atmospheric Administration (NOAA) for an exploration license and a commercial recovery permit for polymetallic nodules in international waters of the Clarion Clipperton Zone (CCZ) in the Pacific Ocean. The application was filed under NOAA’s new consolidated application and review process and represents the first submission of its kind. It covers a ~65,000 km 2 exploration and commercial recovery area in the CCZ, compared to a commercial recovery area of ~25,000 km 2 in TMC USA’s initial commercial recovery permit application from April 2025.

Gerard Barron, Chairman and CEO of TMC, commented: “This new application represents the culmination of more than a decade of disciplined scientific, engineering, and environmental work. It translates years of exploration, testing, and data collection into a single, comprehensive submission for a defined, expanded, and game-changing critical minerals project, with more than 800 million estimated tonnes of nodules containing high-grade nickel, copper, cobalt and manganese — representing a metal grade of approximately 3.2% for nickel equivalent and 7% copper equivalent. We believe it demonstrates both the maturity of our project and our readiness to proceed to commercial operations under the U.S. regulatory framework.” He added: “I want to commend the U.S. Administration for its recognition of critical minerals as a matter of national security and that offshore minerals are a key part of the solution.” The increase in the proposed commercial recovery area is supported by extensive prior work, including multi-year environmental baseline studies , resource assessments , engineering development , and offshore test mining .

The application incorporates data and analyses generated through 27 offshore resource and environmental research cruises (across both NORI-D and TOML-F and inclusive of all phases of the post-test mining sampling program), thousands of seafloor samples, and the largest integrated test mining campaign conducted in the deep sea since U.S.-based consortia first tested technologies in the CCZ in the 1970s. Supported by newly published, peer-reviewed research by independent academics drawing on the Company’s test mining and recovery data—demonstrating that both biodiversity and sediment plume impacts are confined to the directly mined area—TMC is confident that its dataset provides a robust, scientifically grounded basis to commence and responsibly scale its commercial operations. The application outlines a careful phased development approach, beginning with commercial recovery activities in a portion of the license area where nodules and habitats have been extensively characterized and where test mining and monitoring have already been completed.

These prior activities include the successful collection of 3,000 tonnes of polymetallic nodules using a fully-integrated system, comprehensive environmental monitoring from the seafloor to the ocean surface, and pilot- and commercial-scale processing tests demonstrating the conversion of nodules into battery and steelmaking feedstocks. NOAA has played a central role in advancing scientific understanding of deep seabed mining impacts since the 1970s, including conducting environmental research cruises in the Clarion Clipperton Zone (CCZ), monitoring early nodule collection trials, and publishing a Programmatic Environmental Impact Statement covering the CCZ in 1981. The agency issued comprehensive DSHMRA implementing regulations in 1981 (exploration licenses) and 1989 (commercial recovery permits) and has maintained an active licensing program since that time, with multiple exploration licenses renewed on a five-year basis.

The newly effective rule updates this regulatory framework to reflect decades of additional environmental research, data collection, and technological development. Since its founding, the Company has delivered many of the nodule industry’s firsts, uniquely positioning TMC USA to pursue commercial recovery activities expeditiously in accordance with the new NOAA rule.
