Overview

TMC collects polymetallic nodules from the CCZ, about 2,400 kilometers southwest of San Diego, for onshore processing in the United States.

  • The nodules carry nickel, copper, cobalt and manganese in a single rock, alongside rare earths.
  • Founded as DeepGreen Metals in 2011. Began trading on Nasdaq on September 9, 2021, through a business combination with Sustainable Opportunities Acquisition Corp.
  • Runs a capital-light strategy, relying on partners for vessels, engineering and processing capacity.
  • Regulatory strategy runs on two tracks: the ISA contracts under the United Nations Convention on the Law of the Sea, whose commercial mining code remains unfinished, and United States applications to NOAA under DSHMRA, the 1980 statute revived by Executive Order 14285 of April 24, 2025.

Projects and license areas

AreaRegimeSizeStatus
NORI (blocks A, B, C, D)ISA, sponsored by Nauru74,830 km²Contract granted July 2011. Probable reserves declared in NORI-D in August 2025. The ISA Council granted a five-year extension on July 20, 2026.
TOMLISA, sponsored by Tonga74,713 km²Contract granted January 2012. TMC acquired TOML in March 2020. Covered by the August 2025 initial assessment. The contract is due to expire on January 11, 2027, before the ISA’s Legal and Technical Commission is scheduled to consider TOML’s extension application. TOML expects it to be deemed extended from January 12, 2027, under the transitional provision of the ISA’s extension procedures.
TMC USA-AUnited States, DSHMRA, NOAA~65,000 km²Applied for in April 2025. A consolidated exploration license and commercial recovery permit application was filed on January 22, 2026, found fully compliant on April 28, 2026, and published in the Federal Register on August 19, 2026. It raised the commercial recovery area from ~25,000 km². Company estimate of 619 Mt of wet nodules, with a further 200 Mt of exploration upside.
TMC USA-BUnited States, DSHMRA, NOAA~122,000 km²Exploration license application filed April 2025 and certified May 26, 2026. NOAA published a notice of intent to prepare an environmental impact statement on August 17, 2026. Company estimate of 1.02 billion tonnes of nodules.
Port of Brownsville, TexasOnshore processing1,466 acres in two parcelsExclusive right of negotiation on a lease option, for a 12 million tonne a year industrial park. TMC calls the proposed processing plant Nodule City. An internal prefeasibility study by a third-party engineering firm has been done, and a master services agreement with Mariana Minerals of July 21, 2026, starts a phased program of mobilization, concept development and technical design. Any capital commitment is conditional on United States government support.

Project economics

  • Two studies published in August 2025 cover an estimated 1.6 billion tonne resource.
  • The pre-feasibility study covers NORI-D and carries probable reserves.
  • The initial assessment covers the remaining NORI blocks and TOML. It is preliminary, with no reserves.

Partners

  • Allseas Group. Built and tested the pilot collection system that lifted about 3,000 tonnes of nodules from NORI-D in 2022, and is TMC’s largest strategic investor. On May 11, 2026, the two signed a commercial agreement for Allseas to complete, commission and operate the first commercial production system, with a nameplate 3.0 million wet tonnes of nodules a year, using two collector vehicles, a riser, the production vessel Hidden Gem and a transfer vessel. TMC reimburses Allseas’ eligible development costs, half as incurred and half deferred and repaid out of future commercial production volumes. The deferred half remains payable whether or not commercial production begins.
  • Pacific Metals Co. (PAMCO). Calcined and smelted 2,000 tonnes of nodules at its rotary kiln electric furnace plant in Hachinohe, Japan, and is running the processing feasibility work.
  • Korea Zinc. Invested US$85.2 million in June 2025 for 19.6 million shares at US$4.34 plus warrants, taking ~5%, and is partnering on United States refining.
  • Mariana Minerals. Software-first minerals developer founded by Turner Caldwell, a former Tesla executive, signed as strategic partner to run feasibility work on the Brownsville site. On July 21, 2026, TMC USA signed a master services agreement with it for a phased program covering mobilization, concept development and technical design, to establish plant feasibility and design basis.
  • Eco Minerals. On July 22, 2026, TMC signed a mutual master services agreement with the United States explorer for exclusive vessel charter access and seafloor mapping, sampling and autonomous survey services, with TMC providing environmental and regulatory advice in return. A separate memorandum gives Eco Minerals a non-binding offtake for its nodules to be processed at the planned Brownsville facility, subject to definitive agreements, government financing and approvals.
  • Glencore. Holds 50% nickel and copper offtake over part of the contract areas dating to 2012. Its XPS subsidiary smelted nodule-derived calcine in Sudbury, Ontario.
  • The Metals Royalty Co. (Nasdaq: TMCR). Holds a 2.0% gross overriding royalty on the NORI area from a 2023 transaction, and began trading on April 8, 2026. TMC held 13,923,077 shares, 20.65% of it, at September 23, 2026, and retains a right to buy back up to 75% of the royalty.

Where permitting stands

  • January 22, 2026: TMC USA submits a consolidated exploration license and commercial recovery permit application to NOAA.
  • March 9, 2026: NOAA determines the application is in substantial compliance.
  • April 28, 2026: NOAA certifies full compliance. Announced May 1, 2026.
  • May 26, 2026: NOAA certifies the USA-B exploration license application. Announced May 28.
  • August 17, 2026: NOAA publishes a notice of intent in the Federal Register to prepare an environmental impact statement for USA-B. Scoping comments closed on September 16, 2026.
  • August 19, 2026: NOAA publishes the consolidated USA-A application in the Federal Register, which starts the public comment period NOAA treats as a prerequisite to certification. Comments close October 19, 2026, and a virtual public hearing is set for October 13, 2026.
  • Still ahead on each file: certification of USA-A, a draft environmental impact statement and draft terms, conditions and restrictions for public comment, then a final determination.
  • TMC said on August 13, 2026, that certification of the USA-A consolidated application had been delayed by a few months, and that it continues to expect the permit ahead of offshore collection system commissioning targeted for the fourth quarter of 2027.

The ISA track is contested.

  • July 18, 2026: the International Tribunal for the Law of the Sea issues two orders in the NORI and TOML proceedings. TMC says they require the ISA to respect its subsidiaries’ due process rights; the tribunal declined to halt the ISA’s compliance inquiry.
  • July 20, 2026: the ISA Council grants NORI a five-year extension of its exploration contract.
  • August 13, 2026: TMC reports that the ISA has asked the Seabed Disputes Chamber to defer its defense on the merits to March 30, 2027. TMC says that if the request is granted, the merits would not be heard before the second half of 2027.
