Wedoany.com Report on Mar 10th, The National Oceanic and Atmospheric Administration (NOAA) of the United States recently confirmed that the consolidated deep-sea mining application submitted by TMC Metals is "substantially complete." This decision was made under the Deep Seabed Hard Mineral Resources Act and pertains to the exploration and potential commercial exploitation plans of the company's subsidiary, TMC USA, in the Clarion-Clipperton Zone (CCZ) in the Pacific international waters. 
The application covers an area of approximately 65,000 square kilometers, encompassing both exploration and potential commercial exploitation activities. In contrast, TMC USA's initial application submitted in April 2025 only covered 25,000 square kilometers. The company estimates that the expanded area holds approximately 619 million tonnes of wet nodule resources, with an additional exploration potential of about 200 million tonnes. NOAA's consolidated permitting process allows environmental, geological, and engineering data from the exploration phase to be directly used in the commercial exploitation review, which helps streamline the overall approval timeline.
The public comment period for TMC USA's exploration license application has concluded. Company Chairman and CEO Gerard Barron stated, "NOAA's decision reflects the extensive work our team and partners have undertaken to understand this resource and how to develop it responsibly. Following over a decade of environmental studies, successful at-sea trials, and metallurgical processing at a commercial scale, we believe polymetallic nodules can provide the United States with a new, lower-impact source of critical metals. We welcome the streamlined consolidated review process and look forward to the next phase."
The CCZ area is known to contain vast quantities of polymetallic nodules, which contain metals such as nickel, cobalt, copper, and manganese. TMC Metals' application is based on over a decade of environmental baseline studies, scientific research, and marine engineering work conducted in the area, aiming to obtain an exploration license and commercial exploitation permit for polymetallic nodules.
