Why is Seabed Mining Gaining Attention?

The growing focus on seabed mining reflects the urgent global need for new sources of critical minerals to power the energy transition and support technological advancement. As traditional mining faces increasing challenges, the ocean floor has emerged as a promising frontier.

Critical Minerals in Polymetallic Nodules

Polymetallic nodules found on the ocean floor contain concentrated deposits of four primary minerals critical to modern technology:

• Nickel: Essential for EV batteries and stainless steel production
• Copper: Crucial for electrical wiring, renewable energy systems, and EVs
• Cobalt: Key component in lithium-ion batteries and superalloys
• Manganese: Used in steel production and emerging battery technologies

These potato-sized nodules form naturally over millions of years and lie unattached on the seabed, potentially allowing for collection methods that are less disruptive than traditional mining operations that require digging, tunneling, and extensive infrastructure.

What makes these nodules particularly valuable is their high concentration of multiple minerals in a single source. A 2020 study published in Nature Scientific Reports estimated that the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean—where TMC holds exploration rights—contains approximately 21.1 billion dry tons of polymetallic nodules with 6.1 billion tons of manganese, 270 million tons of nickel, 225 million tons of copper, and 44 million tons of cobalt.

Projected Demand Growth for Critical Minerals

According to International Energy Agency (IEA) projections, the global transition to clean energy technologies will drive unprecedented demand growth for critical minerals:

• Copper and rare earth metals: Expected 40% increase in demand
• Nickel: Projected 60% growth driven by battery production
• Cobalt: Anticipated 70% increase in global requirements
• Lithium: Forecasted 90% growth for battery technologies

These dramatic increases reflect the mineral-intensive nature of clean energy technologies compared to their fossil fuel counterparts. For example, an electric vehicle requires six times the mineral inputs of a conventional car, while an onshore wind plant requires nine times more mineral resources than a gas-fired power plant of the same capacity.

The scale of this projected demand has raised serious questions about whether traditional mining alone can meet future needs, especially considering declining ore grades at existing mines and increasing environmental and social challenges associated with expanding land-based operations.

How Does This Investment Support US Strategic Interests?

The Korea Zinc investment in TMC aligns closely with evolving US policy priorities regarding critical mineral supply chains and resource security, reflecting bipartisan recognition of the strategic importance of these resources.

Reducing External Dependency on Critical Minerals

The United States currently faces significant vulnerability due to its heavy reliance on imports for many critical minerals. According to the US Geological Survey's 2023 Mineral Commodity Summaries, the US is 100% import-dependent for manganese and graphite, and over 50% dependent for cobalt—all minerals essential to advanced technologies and defense applications.

This dependency creates strategic vulnerabilities, particularly as many critical minerals are sourced from regions with geopolitical tensions or dominated by competitors like China. The deep-sea mining capabilities being developed by TMC offer a potential alternative source that could significantly reduce these dependencies.

Both the Trump and Biden administrations prioritized critical mineral security through executive actions. The Trump administration issued Executive Order 13817 in 2017 to ensure secure and reliable supplies of critical minerals, while the Biden administration's Executive Order 14017 in 2021 directed a comprehensive review of supply chain vulnerabilities, including those related to critical minerals.

The Korea Zinc investment provides crucial financial support to advance TMC's operations, potentially accelerating the timeline for commercial production of seabed minerals that could enter US supply chains.

CEO Gerard Barron's Strategic Vision

In discussing the Korea Zinc partnership, TMC's CEO Gerard Barron has explicitly framed the deal in terms of its strategic benefits for US interests: "This partnership will help the US build a resilient supply chain for critical minerals essential to our energy transition and national security."

Barron emphasizes that the combination of TMC's resource development capabilities with Korea Zinc's metals processing expertise creates a more complete value chain that can transform raw nodule materials into the finished metal products needed by US manufacturers of batteries, EVs, and renewable energy systems.

This strategic framing reflects TMC's understanding that aligning with national security interests enhances both regulatory support and market positioning. By positioning deep-sea mining as a solution to critical mineral vulnerabilities, TMC potentially gains backing from policymakers across the political spectrum.

What is the Current Landscape of Deep-Sea Mining?

The deep-sea mining industry is in a transitional phase, moving from exploration and research toward potential commercial operations, with various deep-sea mining companies and nations positioning themselves for what could become a significant new mineral resource frontier.

Global Players in Seabed Mining

Several key companies and national initiatives are actively advancing deep-sea mining capabilities:

• The Metals Company (TMC): Leading the commercial development of nodule collection in the Clarion-Clipperton Zone through partnerships with Pacific Island nations (Nauru, Tonga, and Kiribati)
• Impossible Metals: California-based competitor developing what they describe as environmentally sensitive collection methods using autonomous underwater vehicles
• JSC Yuzhmorgeologiya: Russian state-owned enterprise with exploration contracts in the Pacific
• Blue Minerals Jamaica: Developing capabilities to exploit Jamaica's exclusive economic zone
• Marawa Research & Exploration: Kiribati-sponsored entity exploring CCZ resources

Beyond corporate entities, several nations are advancing their own deep-sea mining initiatives:

• Cook Islands: Passed the Seabed Minerals Act in 2022 and is actively exploring its exclusive economic zone, which is estimated to contain billions of tons of manganese nodules
• Norway: In January 2024, the Norwegian parliament approved seabed mining in Norwegian waters, becoming the first European country to officially open parts of its continental shelf to commercial mineral extraction
• Japan: The Japan Oil, Gas and Metals National Corporation (JOGMEC) has conducted extensive research on deep-sea minerals within Japanese territorial waters, particularly focusing on rare-earth elements

Regulatory and Policy Developments

The regulatory framework for deep-sea mining remains in development, creating both uncertainty and opportunity for industry participants:

• International Seabed Authority (ISA): As of 2023, the ISA had issued 31 exploration contracts but has yet to finalize the mining code that would govern commercial exploitation in international waters. The organization has faced delays in developing these regulations, which were originally expected to be completed by 2023.

• National approaches: Countries are developing their own frameworks for territorial waters. Norway's recent approval of seabed mining has been viewed as a potential model for other nations considering similar policies.

• Environmental safeguards: A key focus of regulatory development is establishing appropriate environmental protection measures. The International Union for Conservation of Nature (IUCN) called for a moratorium on deep-sea mining at its Congress in September 2021, highlighting the tension between mineral development and environmental protection.

The regulatory uncertainty presents both a risk and an opportunity for companies like TMC. While delays in finalizing rules could postpone commercial operations, early movers who influence the development of these regulations may gain competitive advantages when commercial activities begin.

What Are the Environmental Considerations?

The environmental aspects of deep-sea mining represent perhaps the most contentious dimension of this emerging industry, with significant debate among scientists, environmentalists, industry representatives, and policymakers.

The Environmental Debate Around Seabed Mining

Proponents of deep-sea mining argue that collecting polymetallic nodules from the seabed could have significantly lower environmental impacts than conventional land-based mining. According to a 2020 study published in Nature Scientific Reports (Paulikas et al.), producing metals from nodules would generate significantly less CO2 emissions—an estimated 70% reduction compared to land-based mining for the same metal content.

These arguments center on several key points:

• No need for deforestation or land clearing
• No permanent infrastructure requirements
• No toxic tailings or acid mine drainage
• Lower CO2 emissions per ton of metal produced
• No displacement of communities

Critics, however, emphasize that deep-sea ecosystems remain among the least studied on the planet, with potential consequences that are difficult to predict. Dr. Craig Smith, a deep-sea ecologist, notes: "The deep sea is the largest biome on Earth and we know very little about it. We must proceed with caution."

Specific environmental concerns include:

• Disturbance of seafloor habitats that may take decades or centuries to recover
• Sediment plumes that could affect marine life far beyond collection sites
• Noise pollution affecting deep-sea mammals
• Potential loss of undiscovered species and ecosystem functions

The DISCOL experiment conducted in the Peru Basin in the 1980s provides some insight into recovery rates. Research published in Nature (2017) found that 26 years after the experimental disturbance, many aspects of the deep-sea ecosystem had not recovered, suggesting long-lasting impacts from seabed disturbance.

Balancing Resource Needs and Environmental Protection

Finding the appropriate balance between accessing needed mineral resources and protecting deep-sea environments requires careful consideration of several factors:

• Science-based approaches: Continued research on deep-sea ecosystems and potential impact mitigation strategies
• Precautionary principles: Establishing conservative limits and safeguards given knowledge gaps
• Monitoring systems: Developing effective technologies and protocols for environmental monitoring
• Protected areas: Establishing representative marine protected areas alongside any mining activities
• Adaptive management: Creating regulatory frameworks that can evolve as new information becomes available

The International Seabed Authority faces the challenge of developing environmental regulations that both protect deep-sea ecosystems and provide a viable framework for mineral production. This includes determining appropriate environmental performance standards, impact assessment requirements, and monitoring protocols.

Some industry participants, including TMC, have committed to environmental principles beyond regulatory requirements, such as setting aside no-take zones and funding independent scientific research. However, environmental organizations remain skeptical about whether commercial-scale operations can be conducted without significant harm to deep-sea ecosystems.

What Are the Investment Implications?

The Korea Zinc investment in TMC represents a significant milestone for the deep-sea mining sector and has notable implications for investors considering exposure to critical minerals and emerging extraction technologies.

Market Positioning for The Metals Company

• Geopolitical factors: As nations compete for critical mineral resources, government policies regarding strategic resources could significantly impact the sector.

Investors considering exposure to this sector should carefully weigh the potential for substantial returns against the technological, regulatory, and environmental uncertainties that remain. The Korea Zinc investment suggests that sophisticated industry participants see significant potential value, despite these uncertainties, creating interesting investment opportunities 2025.

FAQ: Deep-Sea Mining and Critical Minerals

What are polymetallic nodules?

Polymetallic nodules are rock-like formations found on the ocean floor containing concentrated deposits of valuable minerals. These naturally occurring formations develop over millions of years as dissolved metals in seawater precipitate around a core object (such as a shark tooth or rock fragment).

Typically 5-10 cm in diameter (about the size of a potato), nodules primarily contain manganese and iron, along with smaller but economically significant amounts of nickel, copper, cobalt, and rare earth elements. What makes these nodules particularly valuable is that they contain multiple critical minerals in a single source and lie unattached on the seabed, potentially allowing for collection without extensive drilling or digging.

The highest concentrations of commercially viable nodules are found in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean between Hawaii and Mexico, at depths of 4,000-6,000 meters. Understanding polymetallic nodules benefits is crucial when evaluating the economic potential of deep-sea mining.

How does deep-sea mining compare to traditional mining?

Deep-sea mining and traditional land-based mining represent fundamentally different approaches to resource extraction:

Environmental Footprint:

• Deep-sea mining: No deforestation, land clearing, or permanent infrastructure; no acid mine drainage or toxic tailings dams; potential for sediment plumes and disturbance of seafloor habitats
• Land mining: Requires extensive land clearing, creates permanent landscape changes, produces significant waste rock and tailings, often involves toxic chemicals for processing

Social Impacts:

• Deep-sea mining: No displacement of communities, minimal human exposure to hazardous conditions
• Land mining: Often involves community displacement, worker safety hazards, and social conflicts

Resource Concentration:

• Deep-sea mining: Nodules typically contain higher concentrations of target minerals than remaining land deposits
• Land mining: Increasingly targeting lower-grade ores as high-grade deposits become depleted

Operational Challenges:

• Deep-sea mining: Extreme depths (4,000-6,000 meters), remote operations, new technology requirements
• Land mining: Established technologies but increasing challenges with water management, waste disposal, and social license

Carbon Footprint:

• Studies suggest deep-sea mining could produce significantly less CO2 per ton of metal than land-based alternatives, particularly for lower-grade terrestrial ores

The relative impacts of each approach remain a subject of ongoing research and debate among scientists, industry representatives, and environmental organizations.
