TMC Nears Regulatory Milestone in Deep-Sea Mining for Battery Metals

The Metals Company (TMC) has received confirmation from U.S. regulators that its deep-sea mining consolidated application is complete, marking a significant step toward obtaining a final permit for mining in the resource-rich Pacific Ocean floor. The seabed contains critical minerals essential for batteries and renewable energy infrastructure, including nickel, cobalt, copper, and manganese. In March 2026, the National Oceanic and Atmospheric Administration (NOAA) confirmed that TMC's application was in substantial compliance with the Deep Seabed Hard Mineral Resources Act (DSHMRA), covering 65,000 square kilometers in the Clarion Clipperton Zone. This area is known to hold 619 million tonnes of polymetallic nodules, small rocks rich in the metals needed for electric vehicles, smartphones, and renewable energy systems. The approval of TMC's consolidated application aligns with broader U.S. efforts to reduce reliance on Chinese sources for rare-earth materials, which currently dominate 70% of global extraction and 90% of processing. However, the company still faces a comprehensive Environmental Impact Statement (EIS) to assess potential ecological risks. TMC, which reported a nearly $320 million loss in the previous year, remains a pre-revenue, high-risk entity. The company aims to secure a final permit by 2027 and plans to process minerals through existing partners while developing a refining hub in Brownsville, Texas. With approximately $118 million in cash and a recent shelf registration for potential stock sales, TMC is positioning itself to become the first commercial-scale seabed miner, though its success hinges on overcoming regulatory, environmental, and financial challenges.
