Deep‑sea mining in Pacific deemed financially unviable, report says
A report by consultancy Koinon, commissioned by Oceans North, Deep Sea Conservation Coalition, Blue Ocean Foundation, IUCN and Dona Bertarelli Philanthropy, examined the economics of commercial extraction of polymetallic nodules in the Clarion‑Clipperton Zone of the Pacific Ocean.
The analysis, presented at the Deep Sea Dialogues alongside the 31st session of the International Seabed Authority in Kingston, Jamaica, focused on two projects – NORI‑D and TOML (Tonga Offshore Mining Limited) proposed by The Metals Company. It found that 83% of realistic scenarios would generate a financial loss and that there is roughly a 60% chance the investment would never recoup its capital.
The report identified cost overruns as the primary profitability risk, alongside uncertainty about the quantity and concentration of minerals and technical challenges of operating on the ocean floor. It concluded that, under all plausible outcomes, deep‑sea mining would destroy more public value than it creates, offering limited and uncertain financial benefits for the international community and sponsoring states.
