NOAA Publishes Notice of Intent in the Federal Register to Prepare an Environmental Impact Statement for TMC USA’s USA-B Exploration License Application

• The publication of a Notice of Intent (“NOI”) to prepare an Environmental Impact Statement (“EIS”) represents a key milestone in the transparent regulatory approval process for TMC USA’s USA-B exploration license application
• The USA-B application area covers ~122,000 km² of seafloor containing an estimated 1.02 billion tonnes of polymetallic nodules with high grades of nickel, cobalt, copper, manganese, and meaningful quantities of many rare earth elements
• Publication of the NOI in the Federal Register follows NOAA’s earlier certification of the USA-B exploration license application on May 26, 2026
  

NEW YORK, Aug. 17, 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 the National Oceanic and Atmospheric Administration (“NOAA”) has published a Notice of Intent to prepare an Environmental Impact Statement in the Federal Register for the exploration license application submitted by the Company’s subsidiary, The Metals Company USA LLC (“TMC USA”), under the Deep Seabed Hard Mineral Resources Act (“DSHMRA”) and its implementing regulations.

The USA-B application area in the Clarion Clipperton Zone (“CCZ”) of the Pacific Ocean covers ~122,000 km² of seafloor and hosts an estimated 1.02 billion tonnes of polymetallic nodules based on TMC’s Technical Report Summary for the Initial Assessment published in August 2025. In addition to the USA-B exploration license application, TMC USA is also advancing a consolidated application for an exploration license and commercial recovery permit for the USA-A area, which was submitted to NOAA on January 22, 2026, and determined to be fully compliant on April 28, 2026.

Gerard Barron, CEO and Chairman of The Metals Company, commented: “The publication of this Notice of Intent is another milestone in NOAA's methodical review process. We welcome the opportunity to participate in a rigorous Environmental Impact Statement process that invites public input and builds on more than a decade of our own environmental research and engineering, alongside 50 years of environmental research and a dozen other commercial and academic disturbance tests in the CCZ. As we’ve said from the beginning, good regulation should be transparent, predictable and grounded in rigorous baseline studies and impact assessment, and today’s announcement demonstrates that process is continuing as intended.”

The publication of the NOI follows the earlier certification of TMC USA’s application for an exploration license over the USA-B area and represents another key step in a steady, transparent cadence of expected regulatory milestones:

• NOAA will publish for public comment a draft EIS and draft Terms, Conditions and Restrictions (“TCRs”) for TMC USA’s proposed exploration activities on the USA-B area
• Following the public comment period, NOAA will consider comments and the EIS will be finalized
• NOAA will then make a final determination on the issuance of the license and its associated TCRs
  

The Company and its partners have conducted over a decade of scientific research, environmental baseline and impact data collection, and offshore engineering, building one of the most comprehensive datasets ever assembled on polymetallic nodules and their surrounding ecosystems. To date, independent academics have published 41 peer-reviewed studies based on the Company’s dataset collected from Eastern CCZ. Earlier this year, TMC began sharing key findings from its Environmental Impact Assessment publicly as part of two new video series, highlighting how its dataset addresses environmental concerns and how innovation has reduced its environmental footprint. The exploratory activities outlined as part of TMC USA’s USA-B exploration license application are expected to generate significant new data in Central and Western CCZ and, with all academics involved free to publish, the Company anticipates that hundreds more papers will be published over the coming months and years.

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 CCZ, monitoring early nodule collection trials, and publishing a Programmatic Environmental Impact Statement covering the CCZ in 1981. In the 1980s and 1990s, NOAA conducted further research into benthic plumes through its Benthic Impact Experiments program where the agency used a custom-built machine to simulate and study seafloor disturbance. The agency issued comprehensive DSHMRA implementing regulations in 1981 (for exploration licenses) and 1989 (for commercial recovery permits) and has maintained an active licensing program since that time, with multiple exploration licenses renewed on a five-year basis.
