Mining the Abyss: How the Deep-Sea Rush Is Replaying Colonial Extraction in Pacific Waters

The International Seabed Authority — the Jamaica-based intergovernmental organisation established under the 1982 UN Convention on the Law of the Sea to regulate mineral extraction from the international seabed — is under more pressure than at any point in its thirty-year history to authorise commercial deep-sea mining in the Pacific Ocean. The Metals Company, a Vancouver-listed corporation formerly known as DeepGreen Metals, holds exploration licences in the Clarion-Clipperton Zone in the central Pacific, sponsored by the island nation of Nauru under a sponsorship arrangement that Pacific civil society groups have described as "flag-of-convenience mining." Tonga and Kiribati have similarly issued exploration permits in their own exclusive economic zones. Papua New Guinea was the site of the Solwara 1 project, operated by Nautilus Minerals — a company that collapsed in 2019 after PNG communities, investors, and regulators combined to make the project unviable. The industry has not absorbed the lessons of Solwara 1. It has simply moved the extraction theatre.

The deep-sea mining debate is routinely framed in the Western financial press as a technology and investment story: can the minerals on the Pacific Ocean floor be recovered at commercially viable cost, and will they displace terrestrial mining of cobalt, nickel, and manganese? That framing obscures the political economy question that Pacific Island communities, Indigenous rights advocates, and decolonial scholars have been raising since the Nautilus Minerals controversy: who owns the Pacific seabed, who benefits from extracting it, who bears the ecological cost, and who was consulted before the licences were signed?

The Nautilus Minerals Collapse and Its Unlearned Lessons

Nautilus Minerals' Solwara 1 project in the Bismarck Sea, off the coast of Papua New Guinea, was the world's first commercial deep-sea mining venture. The company obtained a mining licence from the PNG government in 2011, constructed the world's first seafloor production system, and raised capital from international investors on the basis of projections showing recoverable copper and gold deposits at commercially competitive grades. By 2019, Nautilus Minerals had filed for creditor protection in Canada. The project had consumed over a billion dollars in investor capital and left PNG communities holding an equity stake — mandated under PNG law — in a company that was now worthless.

The collapse was overdetermined. Nautilus had dramatically underestimated the engineering challenges of operating at 1,600 metres depth in a seismically active zone. It had underestimated the opposition of coastal fishing communities in East New Britain and Manus provinces, whose customary fishing grounds — defined not by coordinates on a legal map but by generations of practice and oral tradition — overlapped with the operational footprint of the project. It had underestimated the scrutiny of international civil society organisations, which documented the absence of meaningful free, prior, and informed consent processes for affected communities. And it had underestimated the fragility of a business model that required sustained investor patience for a technology that had never operated at commercial scale.

Teresia Teaiwa's framework of militarism and commodification applies directly to the Nautilus case: the PNG government's enthusiasm for the project reflected the colonial inheritance of a resource-state model in which the primary function of government is to issue extraction licences to external capital in exchange for royalty revenue and development financing. The communities whose fishing grounds were at risk were not parties to that model; they were obstacles to it. The collapse vindicated their opposition, but it did not return the years of community effort expended in fighting the project, nor did it compensate the investors who lost money partly as a result of community resistance that had been predictable from the start.

The Metals Company and the Nauru Sponsorship Structure

The Metals Company's operations in the Clarion-Clipperton Zone use a legal mechanism that international seabed law specifically created to extend the benefits of deep-sea mineral extraction to developing nations: the sponsoring state system. Under this mechanism, a corporation seeking access to the international seabed area — defined under UNCLOS as the "common heritage of mankind" — must be sponsored by a state, which takes on regulatory responsibility and receives a share of any extraction revenue. Nauru, the world's smallest republic by area and one of the most economically vulnerable Pacific Island states, is the sponsoring state for The Metals Company's primary licence area.

The arrangement has been called a "flag-of-convenience" system for seabed resources by Pacific civil society groups. Nauru's sponsorship provides The Metals Company with access to the ISA licensing process; in return, Nauru receives fees, a future royalty stream, and the appearance of partnership in a global industry. What Nauru does not receive is meaningful control over the pace of extraction, the technology standards applied, the environmental monitoring regime, or the decision about whether extraction should proceed at all. Those decisions rest with the ISA's Legal and Technical Commission, a body whose members are drawn primarily from states and institutions with commercial interests in extraction — and whose proceedings, civil society observers have documented, are systematically opaque.

In 2021, Nauru triggered a provision in UNCLOS that required the ISA to complete its deep-sea mining regulations within two years — a deadline that passed without full completion, leaving the regulatory framework in a legal limbo that The Metals Company has characterised as an opportunity and Pacific environmental advocates have characterised as a scandal. The "two-year rule" trigger was itself an act of corporate pressure on a small island state: Nauru was given to understand, by commercial partners, that triggering the deadline would accelerate the regulatory process in ways favourable to extraction. The sovereignty of a Pacific micro-state was instrumentalised to serve the interests of a Toronto-listed corporation.

The Structural Frame: - and Seabed Rents

The economic logic of deep-sea mining as currently structured replicates what Pacific Island states that sponsor seabed mining licences — Nauru, Tonga, Kiribati — will receive royalties on raw nodule extraction. The processing of those nodules into battery-grade nickel, cobalt, and manganese, and the manufacturing of the batteries into which those materials go, will occur in facilities controlled by corporations headquartered in wealthy countries. The value chain is familiar. So is the distribution of its rents.

Joseph Stiglitz's analysis of natural resource extraction in developing economies is directly applicable: the combination of information asymmetries between corporate actors and small-island governments, the absence of independent technical regulatory capacity in Pacific Island states, and the structural incentives of ISA governance toward extraction rather than conservation creates conditions in which even a nominally fair royalty arrangement will transfer the overwhelming majority of value to corporate shareholders rather than Pacific communities.

Greg Fry's Pacific-way framework would argue that the solution is not a better royalty rate but a different governance architecture — one in which Pacific Island states collectively exercise authority over their shared maritime resources through Pacific Islands Forum mechanisms, rather than individually entering bilateral sponsorship arrangements with corporations that are structurally better resourced to negotiate.

What Epeli Hauʻofa Would Recognise

Hauʻofa's sea-of-islands reimagining of Oceania was explicitly directed against the idea that Pacific peoples are peripheral actors in a world defined by metropolitan centres. The deep-sea mining rush — with its governance architecture centred on Jamaica (ISA), its corporate actors based in Toronto and London, its scientific expertise concentrated in European and North American research institutions, and its political lobbying conducted in Geneva and New York — is the latest iteration of the metropolitan-periphery model that Hauʻofa argued Pacific peoples must resist.

The minerals on the Pacific Ocean floor were formed over millions of years in waters that Pacific peoples have navigated, fished, and governed culturally for thousands of years. The legal framework that is now being used to licence their extraction was written by diplomats who did not consult Pacific communities, interpreted by a regulatory body whose transparency Pacific civil society groups have consistently criticised, and enforced by a mechanism that turns Pacific micro-states into licensors of their own dispossession.

The Nautilus Minerals collapse proved that communities can resist. The question for the 2020s is whether Pacific Islands Forum institutions can translate that community resistance into a regional governance framework that treats the Pacific seabed — in Hauʻofa's terms — as part of the Pacific world that Pacific peoples have the right to govern, rather than as an unexploited resource frontier that awaits the arrival of external capital.

Monexus treats the ISA governance crisis as a Pacific sovereignty story, because that is what it is once you move the frame from Toronto to Tarawa.
