NOAA Grants The Metals Company Substantial‑Compliance Determination for Clarion‑Clipperton Zone Mining Application

NOAA announced that The Metals Company USA LLC’s consolidated application for an exploration license and commercial recovery permit under the Deep Seabed Hard Mineral Resources Act covers roughly 65,000 km² of the Clarion‑Clipperton Zone in international waters. The application estimates a resource of 619 million tonnes of wet polymetallic nodules, with an additional 200 million tonnes of potential upside. The determination confirms that the company’s environmental, geological and engineering data meet the Act’s standards, allowing the review to advance to the next stage of the permitting process.

The decision is a pivotal regulatory milestone. NOAA’s consolidated application framework, effective January 21 2026, streamlines the traditional two‑step process by allowing exploration‑phase data to be incorporated into the commercial recovery review. By achieving substantial compliance, The Metals Company removes a major hurdle in its U.S. permitting pathway and positions itself to obtain a commercial recovery permit, a prerequisite for commercial mining operations. The company has targeted a fourth‑quarter 2027 start of production, contingent on final approval of the commercial recovery permit.

Gerard Barron, chairman and CEO, said, “NOAA’s determination reflects the depth of work our team and partners have put into understanding this resource and how it can be responsibly developed. After more than a decade of environmental research, successful offshore trials and commercial‑scale metallurgical processing, we believe polymetallic nodules can provide a new and lower‑impact source of critical metals for the U.S. We welcome the streamlined consolidated review process and look forward to the next stages.” The quote underscores the company’s long‑term commitment to environmental stewardship and its strategic positioning within the U.S. critical‑metals supply chain.

The Clarion‑Clipperton Zone is recognized as a vast deposit of polymetallic nodules rich in nickel, copper, cobalt and manganese, and its development aligns with U.S. policy to reduce reliance on foreign sources of critical metals. While the International Seabed Authority has faced delays in establishing a governance structure for commercial mineral recovery, the U.S. permitting pathway offers a viable alternative for companies willing to meet stringent environmental and technical standards. The Metals Company’s decade‑long research program and successful offshore trials demonstrate its capacity to address the environmental concerns that have historically challenged deep‑sea mining projects.

The substantial‑compliance finding is expected to strengthen investor confidence and accelerate the company’s transition from a pre‑revenue developer to a commercial producer. The company’s capital‑intensive operations will require continued investment, but the regulatory progress reduces uncertainty and clarifies the timeline for obtaining the final commercial recovery permit. With the pathway to production now clearer, The Metals Company can focus on securing financing, finalizing engineering designs, and preparing for the next phase of development.
