Seafloor Elements collects polymetallic nodules — four critical metals in a single rock — from the deep abyssal plain, to build a secure American supply chain.
Polymetallic nodules lie unattached on the seafloor — potato-sized rocks that hold high grades of nickel, cobalt, copper and manganese. There is no overburden to strip, no rock to blast, no tunnels to dig. The nodules are simply collected from the surface of the seabed.
A 1.6-billion-tonne nodule resource sits on the abyssal plain — the largest undeveloped source of energy-transition metals known.
Explore the resource →A tracked seabed collector — designed and built with our robotics partner — harvests nodules 4 km down and lifts them to the surface.

Our environmental approach →Executive Order 14285 opened an expedited U.S. permitting path for seabed minerals. The first commercial-recovery application has been deemed fully compliant, with a grant expected in early 2027 — and in 2026 the U.S. Department of War told the Senate that a resilient critical-minerals supply chain is a national-security priority, backed by federal funding tools.
Building this industry, responsibly. Seafloor Elements is an early-stage company assembling a capital-light operating model and a custom robotic collection system. We believe deep-ocean nodules can be collected with the lowest practicable impact — and that the data should prove it. Get in touch →
