Seafloor Nodules: As Big as Offshore Oil & Gas?

September 18, 2026·46 min
Episode Description from the Publisher

Amanda Van Dyke of the Critical Minerals Hub joins Howard Klein to discuss the growing critical minerals supply gap, why mine development is taking longer and becoming more expensive, and how seafloor mining could emerge as a major new source of nickel, cobalt, copper, and manganese. We also examine The Metals Company (NASDAQ: TMC), U.S. critical minerals policy, deep-sea mining economics, permitting, technical risks, and what investors should watch as the sector moves toward commercialisation.
