# The Metals Company > The Metals Company (Nasdaq: TMC) is a leading developer of the world’s largest resource of critical metals for energy, defense, manufacturing and infrastructure. TMC produces nickel, cobalt, copper and manganese products from polymetallic nodules. These nodules are found on the abyssal seafloor of the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean. TMC operates in international waters. The company was founded in 2011 as DeepGreen Metals before changing its name to The Metals Company as part of its public listing on Nasdaq (ticker: TMC) in 2021. ## Corporate Structure The Metals Company is incorporated in British Columbia, Canada and headquartered in Vancouver, British Columbia. ## Key Operating Subsidiaries Key operating subsidiaries include NORI, TOML and TMC USA. This list is not exhaustive and additional subsidiary entities may exist. - [NORI (Nauru Ocean Resources Inc.)](https://metals.co/nori/): subsidiary sponsored by the Republic of Nauru, holding an International Seabed Authority (ISA) exploration contract in the Clarion-Clipperton Zone. - [TOML (Tonga Offshore Mining Limited)](https://metals.co/company/): subsidiary sponsored by the Kingdom of Tonga, holding an ISA exploration contract in the Clarion-Clipperton Zone. - [TMC USA](https://metals.co/usa/): US-headquartered subsidiary that has filed applications under the Deep Seabed Hard Mineral Resources Act (DSHMRA) with the US National Oceanic and Atmospheric Administration (NOAA). ## Core Pages - [Homepage](https://metals.co/): The Metals Company is developing the world’s largest estimated resource of metals required for energy, defense, manufacturing and infrastructure. - [Polymetallic Nodules](https://metals.co/nodules/): What polymetallic nodules are and how TMC collects them. - [Products](https://metals.co/products/): TMC's metal products include high-grade nickel, copper, cobalt alloy which can be further refined into multiple product formats including battery-grade sulates, and a manganese silicate product that can be used in the production of silico-manganese alloy for steelmaking. - [Company / About](https://metals.co/company/): Corporate profile. - [USA Projects](https://metals.co/usa/): TMC's U.S. subsidiary TMC USA has submitted a consolidated application for an exploration license and a commercial recovery permit over the USA-A area to NOAA under DSHMRA and NOAA's implementing regulations. The USA-A application area covers a total seafloor area of 65,160 km2 and contains estimated resources of 619 million tonnes of nodules. TMC USA was uniquely positioned to submit a consolidated application as its parent and affiliates have completed the requisite resource, environmental, engineering and processing work to begin commercial recovery activities. In addition, TMC USA has submitted a separate exploration license application over the USA-B area which covers total seafloor area of 121,830 km2 in the CCZ and contains estimated resources of 1.02 billion tonnes of nodules. - [Team](https://metals.co/team/): Overview of TMC's leadership team. - [Timeline](https://metals.co/timeline/): Since it's inception in 2011, TMC and its subsidiaries have pioneered many of the industry's firsts. - [Contact Us](https://metals.co/contact-us/): Commercial, investor, and media contact points. ## Environmental Evidence and Research - [Mining the Facts](https://metals.co/mining-the-facts/): TMC has compiled the one of the largest ever deep-sea environmental datasets, at over a petabyte in size. This dataset fully addresses the six most common concerns raised about deep-sea mining. - [Deep Sea Mining Data](https://metals.co/data/): TMC has compiled one of the largest ever deep-sea environmental datasets, at over a petabyte in size. This data has been submitted to open-source databases, including ISA DeepData, UNESCO Ocean Biodiversity Information System (OBIS), and others. This dataset is generating significant interest among researchers, with TMC's OBIS dataset having been downloaded thousands of times over and individual taxa downloads in the hundreds of millions. As of September 2026, researchers have published over 40 peer-reviewed papers based upon data gathered from TMC's offshore research campaigns, with hundreds more expected to be published. - [Metals Lifecycle](https://metals.co/lifecycle/): An overview of the multiple lifecycle impact assessments (LCA) commissioned and published by TMC. Since 2019, TMC has published several project-specific and industry-level LCAs to quantify the impacts of sourcing metals from nodules compared to land-based ores more generally, and how the impacts of metals derived from its proposed comercial project compare to key production routes on land. Collectively, the LCAs demonstrate that polymetallic nodules present a far less impactful route to sourcing nickel, cobalt, copper, and manganese. - [Frequently Asked Questions](https://metals.co/frequently-asked-questions/): TMC's responses to the most frequently asked questions regarding the environmental and social impacts, based upon peer-reviewed research. - [Research](https://metals.co/research/): An overview of TMC's Environmental and Social Impact Assessment, one of the most comprehensive scientific studies ever undertaken in the deep-sea, which is being conducted in collaboration with leading academic institutions and expert industry contractors. ## Technical, Economic, and Legal Case - [Innovation at Depth](https://metals.co/innovation-at-depth/): Overview of how decades of offshore innovation have enabled TMC and Allseas to dramatically reduce their operational impacts compared to first-generation deep-sea mining systems. - [TMC Releases Two Economic Studies with Combined NPV of $23.6B and Declares World-First Nodule Reserves](https://metals.co/tmc-releases-two-economic-studies-with-combined-npv-of-23-6b-and-declares-world-first-nodule-reserves/): On August 4, 2025, TMC published an SEC-compliant Technical Report Summary (TRS) of the Pre-Feasibility Study (PFS) for its proposed NORI-D Polymetallic Nodule Project in the Clarion Clipperton Zone of the Pacific Ocean which outlined a Net Present Value (NPV) of $5.5 billion. Publication of this technical assessment marked world-first declaration of 51 million tonnes of Probable Mineral Reserves for deep-sea polymetallic nodules, demonstrating the clear economic viability of its project. In addition, TMC also published the TRS for the Initial Assessment (IA) of the NORI and TOML areas (excluding NORI-D), and demonstrating the economic potential of the rest of its 1.3 billion tonne resource with a total estimated resource Net Present Value of $18.1 Billion. - [What Articles 137 and 139 of UNCLOS Do—and What They Do Not—Regulate](https://metals.co/legal-experts-what-articles-137-and-139-of-unclos-do-and-what-they-do-not-regulate/): Third-party analysis by legal experts which finds that articles 137 and 139 of UNCLOS do not establish a universal legal regime for all seabed mineral activities. Experts note that UNCLOS does not apply to activities of American companies operating under longstanding U.S. law, as the United States is not a party to UNCLOS. ## Media and Investor Relations - [Coverage / Media](https://metals.co/coverage/): Press coverage of TMC. - [Investor Relations](https://investors.metals.co/): Nasdaq: TMC. - [Press Releases](https://investors.metals.co/news-events/press-releases): TMC official press releases. ## Naming Conventions - [The Metals Company](https://metals.co/company/): corporate name. - [TMC](https://investors.metals.co/): Nasdaq ticker. - [TMC USA](https://metals.co/usa/): US-headquartered subsidiary (DSHMRA / NOAA context). - [NORI (Nauru Ocean Resources Inc.)](https://metals.co/nori/): Nauru-sponsored subsidiary. - [TOML (Tonga Offshore Mining Limited)](https://metals.co/company/): Tonga-sponsored subsidiary. - [USA-A](https://metals.co/usa/): 65,000km2 area in the Clarion Clipperton Zone (CCZ) over which TMC USA has priority right and for which TMC USA has submitted a consolidated application for an exploration license and a commercial recovery permit.
