Deep-sea mining targets polymetallic nodules rich in nickel, cobalt, copper and manganese—strategic metals for the energy transition. The sector is still pre-commercial and sits in a regulatory limbo: the International Seabed Authority (ISA) has not yet finalized a Mining Code, while global pressure for a moratorium grows on environmental grounds. Supporters argue it could reduce reliance on high-impact terrestrial supply chains, but scientific consensus warns of long-term damage to abyssal ecosystems.
Economically, project valuations are highly sensitive to nickel prices, offshore engineering costs and access to long-term offtake agreements. For investors, listed developers behave like binary options on regulation and geopolitics—high upside if a legal framework unlocks projects, but equally high downside from delays, financing risk and political backlash. In short: strategic but speculative.
