Definition and Scope

Deep-sea mining extracts critical minerals from ocean floor deposits beyond 400m depth, targeting polymetallic nodules (Clarion-Clipperton Zone), cobalt-rich crusts (Pacific seamounts), and seafloor massive sulfides (hydrothermal vents).
These deposits form under specific conditions. Polymetallic nodules lie on abyssal plains at 4,000-6,000m, rich in manganese, nickel, copper, and cobalt. Companies eye them for high-grade metals suited to electric vehicle batteries.
Cobalt-rich crusts coat seamounts at 400-4,000m, holding cobalt, platinum, and rare earth elements. Seafloor massive sulfides cluster near hydrothermal vents at 1,000-4,000m, packed with copper, zinc, gold, and silver. Each type draws interest from mining firms testing extraction tech.
The International Seabed Authority (ISA) oversees Areas Beyond National Jurisdiction under UNCLOS Article 133, which limits scope to nodules, sulfides, and crusts. Target metals like nickel, copper, cobalt, and manganese meet surging demand from EV batteries, with each Tesla Model 3 needing 70kg of cobalt.
- Nickel powers battery cathodes for longer range.
- Copper enables efficient wiring in renewables.
- Cobalt stabilizes high-performance cells.
- Manganese supports cost-effective alternatives.
Historical Development
Deep-sea mining exploration began in 1965 when J.L. Mero published The Mineral Resources of the Sea, estimating 1.3 trillion tons of polymetallic nodules in Pacific basins. This book sparked interest in ocean mining potential for metals like nickel, copper, and manganese. It laid the groundwork for international efforts to regulate seabed resources.
In the 1970s, the UN Seabed Committee formed to address deep ocean exploration. This led to the 1982 United Nations Convention on Law of the Sea (UNCLOS), which established the International Seabed Authority (ISA) for high-seas mining oversight. The 1994 ISA Convention resolved key disputes, enabling exploration licenses.
Key milestones include the 1978 Ocean Mining Administration in the USA and the 2011 Nautilus Minerals Solwara 1 permit, the first for seafloor massive sulfides. By 2021, ISA faced moratorium debates amid environmental concerns. Several projects failed, such as Nautilus Minerals’ 2019 bankruptcy due to upfront costs and technology issues.

Future Outlook and Investment Recommendations
First commercial nodule production in 2026-2027 promises strong returns despite notable execution risk, favoring diversified $50-100M allocations. The $16T resource potential in polymetallic nodules and other seabed deposits draws interest from venture capital and sovereign wealth funds. Yet, regulatory hurdles from the International Seabed Authority (ISA) and environmental concerns balance this appeal.
Deep-sea mining faces execution risks like technology development and permitting delays, but rewards tie to rising demand for critical minerals such as nickel, copper, and cobalt. Investors should weigh geopolitical tensions in exclusive economic zones (EEZs) against supply shortages from land-based mining depletion. A phased approach mitigates upfront costs and operational expenses.
Phased investment starts with pilot projects using remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs), scaling to commercial operations by 2030. Companies like The Metals Company and Allseas advance marine mining technology for polymetallic nodules and seafloor massive sulfides. Experts recommend monitoring ISA exploitation contracts for entry timing.
Balancing investment risks and rewards requires focus on sustainable mining practices, including baseline studies and monitoring programs. Adaptive management addresses seabed disturbance and sediment plumes. Long-term, green energy transition drives demand, supporting economic viability.
