DeepGreen gets mining rights with acquisition of TOML

DeepGreen Metals has acquired Tonga Offshore Mining Limited (TOML) from Deep Sea Mining Finance, giving the company exploration rights to a block of Clarion Clipperton Zone (CCZ) of the Pacific Ocean seabed.

The acquisition gives company the access to a 74,713 km2 block that contains an inferred resource of 756 million wet tonnes of polymetallic nodules.

TOML holds an exploration contract granted by the International Seabed Authority (ISA) and sponsored by the Kingdom of Tonga.

As part of the TOML acquisition, DeepGreen will benefit from existing environmental studies, a Canadian NI 43-101 compliant technical resource report and an intellectual property portfolio, the company noted.

The acquisition of a third exploration area, together with the news that DeepGreen’s offshore engineering partner Allseas has acquired a former ultra-deepwater drill ship for conversion to a polymetallic nodule collection vessel, makes DeepGreen a front-runner in a new industry that promises to reshape how critical battery metals are sourced, processed and recycled.

The electrification of global transport and buildout of renewable energy storage will require hundreds of millions of tonnes of nickel, cobalt, copper and manganese. Industry analysts and electric vehicle manufacturers have raised concerns over availability as well as environmental and social costs of producing these metals.

The CCZ seabed contains the world’s largest known deposits of nickel, cobalt and manganese. Several Areas of Particular Environmental Interest encompassing 1.44 million km2 have been set aside, which are intended to represent CCZ habitats and will be protected from resource extraction.

Current exploration contracts in the CCZ account for 1.2 million km2 and are estimated to contain enough metal to electrify the entire global car fleet.

We believe now more than ever that the world needs to work together to find solutions to address climate change. The TOML project will enable us to bring more critical mineral resources to market to break through the bottleneck and shift away from fossil fuels,” said Gerard Barron, CEO and chairman of DeepGreen. “Our research shows that ocean polymetallic nodules can provide society with these metals at a fraction of the environmental and social impacts associated with land-based extraction.” 

Uncertainties remain around the scope and scale of the impact of nodule collection on deep-sea ecosystems and biodiversity. To address these uncertainties, DeepGreen, in partnership with over 100 scientists from the world’s leading marine science institutions, is currently undertaking the world’s largest integrated ocean surface-to-seabed research program encompassing over 75 studies in order to fully understand the impacts of collecting nodules from the ocean floor.

The TOML acquisition expands DeepGreen’s extensive library of deep-sea research in the CCZ. It now contains 10,450 preserved biological samples, including 5,750 infauna samples, 2,500 sediment metagenomic samples and 2,200 megafauna specimens. The company’s library also contains 3,153 line-kilometers of seabed images and 115,591 square kilometers of high-resolution bathymetric data.

Combining the company’s expanded environmental data library with the ongoing science program will make the Eastern CCZ one of the most well-studied parts of the deep ocean by the time DeepGreen completes its Environmental and Social Impact Statement and applies to the ISA for an exploitation contract in 2022.

With DeepGreen, the Kingdom of Tonga has a committed partner dedicated to equitable development of this common heritage resource,” said Gerard Barron.

In addition to TOML, sponsored by the Kingdom of Tonga, DeepGreen’s other contract areas in the CCZ are sponsored by the governments of Nauru and Kiribati, creating a multinational force of Pacific Small Island Developing States that the company believes can help rebalance power in the global development of minerals that are critical for the 21st century.

“Past industrialisations had richer countries exploiting the natural resources and labor of poorer countries, which locked them into what became known as the ‘resource curse’, leaving many poorer countries perpetually underdeveloped and unstable,” added Gerard Barron.

“But with the potential for deep-sea nodules to help drive the green transition, our sponsoring states can consider themselves as ‘Big Ocean States’ with real agency through the ISA, enabling Pacific Islanders to shift the balance of power as we take on the urgent challenge of decarbonising the global economy.”
