Norway to Map Deep Sea Mineral Deposits

Maritime Executive | 12 August 2018

The Norwegian Petroleum Directorate is readying to map potential deep sea mineral deposits in the Norwegian Sea, with an expedition due to get underway this month.

The Directorate has engaged Swire Seabed, which partners with Ocean Floor Geophysics, to carry out mapping of potential sulfide minerals on the seabed over the Mohns Ridge in the western Norwegian Sea. This is a spreading ridge in the Atlantic Ocean that separates two oceanic plates, where potential valuable minerals have been formed through hot volcanic sources. The focus of the expedition is not the active hydraulic systems such as “black smokers,” but rather non-active extinct systems that are now left as mineral-rich piles of gravel on the seabed.

The mapping will be carried out using an autonomous underwater vehicle, a Kongsberg Hugin AUV, which will map the seabed using a bottom-penetrating echo sounder, multibeam bathymetry, synthetic aperture sonar data, magnetometry and spontaneous potential field data.

After the data is processed on board, mineral samples will be taken from the seabed where the data indicates the presence of deposits. Sampling will be carried out using an underwater remotely operated vehicle with a depth capability of 3,000 meters (9,800 feet).

Earlier studies by the Norwegian Research Council have indicated that the region could contain resources worth as much as $110 billion. Around 6.4 million tons of copper metal in addition to zinc (6.5 million tons), gold (170 tons) and silver (9,901 tons) have been estimated to be present in the region. 

Rising demand for minerals and metals, including for use in new technology, has sparked renewed interest in seabed mining. Since 2001, the International Seabed Authority has issued licenses to approximately 30 government and private organizations to explore 500,000 square miles of the deep sea outside national jurisdiction for minerals. 

This increasing interest in seafloor mining globally has drawn some criticism. Despite the term “mining,” much of the activity would involve extraction of minerals over very wide areas of the sea floor rather than digging down to any great depth, potentially leaving a vast footprint on the deep-sea habitats in which these mineral deposits occur. Earlier this year, a study by the University of Exeter and Greenpeace warned that mining on the ocean floor could do irreversible damage to deep sea ecosystems. The deep sea (depths below 200m) covers about half of the Earth’s surface and is home to a vast range of species. Little is known about these environments, and the researchers say mining could have “long-lasting and unforeseen consequences” not just at mining sites but also across much larger areas.

Another NZ seabed mining permit lapses

Another seabed mining permit lapses: industry future is in question

KASM | Scoop NZ | 1 August 2018

The news that seabed mining company Trans Tasman Resources Ltd (TTR) has let yet another New Zealand mining permit lapse was heralded today by Kiwis Against Seabed Mining.

On Thursday last week, the TTR prospecting permit for a 4435 square kilometre section of the seabed off the West Coast quietly lapsed, and is not being renewed. This is the second such permit the company has allowed to lapse in the last six months, the first being near Kawhia off the North Island’s West Coast just south of Raglan.

The company has confirmed that it has let the permit lapse as it waits for the result of a High Court appeal (heard in April) brought by KASM and a number of other interests against the EPA’s consent for mining a 66sqkm area of the South Taranaki Bight seabed. Whatever the outcome of the appeal, there will be a long process before it’s resolved, with the possibility of more court action, or another EPA hearing.

“This gives the Government an opportunity to re-think the logic of these seabed mining bids off our coastlines, not least because of the threat to endangered species like Māui and Hector’s dolphins, fisheries, seabirds and our surf breaks,” said KASM chairperson, Cindy Baxter.

“After years of effort, where are we? Two seabed mining applications have been refused, a third is under appeal, permits are dropping like flies, the companies are struggling financially, there are still huge concerns around the environmental impact, and opposition is growing stronger by the day. It’s time for the government to put a stop to this madness.”

The environmental costs of deep-sea mining

Countries must determine if mining the ocean can be done without harm to the environment

Matthew GianniDuncan Currie | china dialogue | 26 July 2018

There is growing interest in opening up the deep-sea to industrial mining for copper, nickel, cobalt, gold, rare earths and other metals. But at what cost?

The International Seabed Authority (ISA) is meeting this week to discuss a strategic plan for the development and regulation of mining in the deep ocean beyond national waters.

The ISA was established in 1994 under the United Nations (UN) Convention on the Law of the Sea. It is responsible for deciding whether, how and under what conditions, mining could be permitted in the international area of the seabed, an area equal to about a third of the earth’s surface.

The ISA has already issued 29 contracts to companies and state agencies from China, Korea, Japan, UK, Germany, Belgium, France, Russia, Brazil, India, Poland and a number of South Pacific countries to explore for metals in the Pacific, Atlantic and Indian oceans.

Biodiversity at risk

But the deep-sea is increasingly recognised as one of the largest reservoirs of biodiversity on the planet and critical to supporting planetary ecological systems.

This first World Ocean Assessment report, published by the UN in 2016, also concluded that deep-sea ecosystems are already stressed by climate change, pollutants, and other human activities. Even plastics are making their way into the deep ocean. A recent study found plastics in the stomachs of fish in depths of 11,000 metres – the very deepest parts of the ocean.

Several scientific papers published in the past year have concluded that if deep-sea mining is allowed then biodiversity loss is inevitable. This is because many deep ocean species are long-lived, and ecosystems will struggle to recover, or may never recover, from mining impacts.

Other studies have pointed to the uniqueness of deep-sea hydrothermal vent ecosystems that harbour chemosynthetic life forms such as giant tubeworms. These recent discoveries have vastly broadened our understanding of how life has evolved on our planet.

The vents also form mineral deposits known as polymetallic sulfides. The ISA has issued exploration licenses for these, but if active vents are mined then the life that thrives in these rare ecosystems will be destroyed.

Weighing the risks

Given the role of the deep-sea and the vulnerability of species and ecosystems to long-term and potentially irreversible damage, it is important that we first understand the risks before deciding whether, and under what conditions, deep-sea mining could be permitted to occur.

This is the essence of a resolution adopted by the European Parliament in January of this year, which called for a moratorium on deep-sea mining until the risks are fully understood.

The Parliament also called for greater transparency by the ISA so that it ensures “effective protection” of the marine environment. This, after all, is its obligation under the Convention on the Law of the Sea. The ISA is also charged with acting for the “benefit of mankind as a whole” as the global steward of the international seabed, referred to in international law as the “common heritage of mankind”.

The UN’s 2030 Sustainable Development Goals (SDGs), adopted in 2015, commit all countries to rethink their economies, their use of the earth’s natural resources, and the protection of our oceans and wider environments in the context of sustainable development.

SDG 14 commits all nations to conserve and sustainably use the oceans, seas and marine resources for sustainable development. We need to conserve the ocean and we need to be investing in reusable technologies, recycling, and better product design to ensure we make the best use of the resources we have.

SDG 14 also commits nations to protecting and restoring ocean ecosystems and enhancing their resilience to be able to better survive the harmful effects of climate change.

The Chinese government has repeatedly told the ISA that it needs to take time for careful consideration and scientific study, while other voices are clamouring for rapid action and adoption of regulations to allow deep-sea mining.

China Ocean Mineral Resources Research and Development Association (COMRA) recently held a workshop in Qingdao to start development of a Regional Environmental Management Plan (REMP) for an area of the western Pacific where China, Russia, Japan and Korea have exploration claims for cobalt crust mining on seamounts. REMPs are essential environmental tools to assess the regional characteristics and environmental needs.

Countries must seriously weigh whether deep-sea mining is consistent with the Sustainable Development Goals and their obligations under international law. Is it worth the risk of significant biodiversity loss and the degradation of deep ocean ecosystems? This is a debate that should occur this week at the ISA and within the broader international community of nations as a whole. The future of our oceans is at stake.

Oceans Face Ultimate Threat from Deep Sea Mining

New Website & Letter Signed By International Scientists & Organizations Urging for a Moratorium on Deep Sea Mining 

MiningWatch Canada | July 24 2018

Our international waters – known as the “common heritage of (human)kind” – are under a new, imminent, and most deadly threat from the deep sea mining industry. 

The International Seabed Authority (ISA), a UN agency which has not received much public scrutiny until now, meets in Kingston, Jamaica this week to discuss how to open up the deep sea bed to mining. Scientists, academics, and non-governmental organizations unite in a joint letter to raise alarm over this ultimate threat to our oceans.

Nnimmo Bassey, Director, HOMEF foundation and Alternative Nobel Prize recipient stated:

“Oceans play a critical role in maintaining life on the planet. However, the ISA continues to ignore the profound lack of scientific understanding of the immediate and long-term ecological costs of digging up the sea floor. 

“It is evident that large private and state-owned conglomerates have succeeded in shifting the ISA’s regulatory discussions toward outcomes favourable to corporate-directed industrial development.”

“Our joint letter is a call from civil society globally to protect our common heritage.”

Renowned marine biologists, including Cindy Van Dover and colleagues, have recently pointed out that deep-sea mining would impact both the seabed and the water column, such that biodiversity loss would be both “unavoidable” and “likely to last forever on human timescales.”

“The world’s seas are already on the brink of catastrophe from overfishing, pollution, such as from plastics and chemicals, destruction of critical habitat such as mangroves and coral reefs, global warming and acidification” said Catherine Coumans of MiningWatch Canada.

“The oceans cannot survive wide scale destruction of the sea bed by the same irresponsible industry that mines on land.” 

The signers of the joint letter noted:

“This is not the time to move forward with an extractive regime; there are far too many uncertainties. International leadership at the ISA is required to prevent recklessly proceeding with deep-sea mining.”

The ISA has already issued numerous exploration contracts in international waters to mining interests supported by member states of the ISA. As these exploration contracts come to an end, the ISA is considering implementing a regime to allow extraction.

Raj Patel, Activist, New York Times best-selling author and Research Professor, University of Texas claimed:

“When the Law of the Sea was written and the idea of ‘common inheritance’ first framed, I’m certain that corporations weren’t intended to inherit the seabed. There’s little evidence that corporate stewardship is compatible with the continued, sustained health of these under-studied ecosystems.”

“The seabed is everyone’s common inheritance, and we need broad, transnational and formal public consultation to learn and then decide how best to ensure its survival for those who will inherit it from us.”

Rather than permitting deep sea mining the ISA must declare a moratorium on deep sea mining before irreparable damage is done to the health of the world’s oceans.

Nautilus’ stock plummets as deep sea mining litigation proceeds

Deep Sea Mining Campaign | 17 July 2018

Today Nautilus Minerals Solwara 1 deep sea mine project will be at the centre of a court hearing in Papua New Guinea as local communities seek to enforce their legal rights to full information about the project.

Andy Whitmore, Finance campaigner from the Deep Sea Mining campaign said, “We were informed that Nautilus told its shareholders at their AGM that the legal case bought by local communities in PNG to stop the Solwara 1 project had been dismissed on June 18.”

“It is also alleged that Nautilus stated to shareholders they believed the government of PNG was going after community for cost recovery because it was a spurious lawsuit.” 

“This is misinformation from Nautilus!” claimed Jonathan Mesulam from the Alliance of Solwara Warriorsa local community leader whose village is located 25km from the Solwara 1 project.

“There is still a legal case registered at Waigani National Court House. The case, which was adjourned on June 18, will be heard today.”

“The real question is this: why is the government trying to dismiss this case? Why would government resources be invested in blocking this case over the constitutional right of all PNG citizens to Freedom of Information?”

Nautilus stock fell by 19% this month after a string of bad news stories. These include the contract with their shipbuilding supplier had been canceled, major mining company Anglo American divesting its’ shares from the company and that the majority of the local community in New Ireland province oppose the renewal of Nautilus’ exploration license.

“Local community around the Community Beneficiary Area (CBA) have all objected to the renewal of Exploration License 1196 through written objection which was lodged at the Mineral Resources Authority (MRA) in March this year. There was also strong objection during the Warden hearing in April” continued Mr. Mesulam.

“New Irelanders are now well informed of the potential impact of Nautilus Minerals and their experimental seabed mining project. They are giving their undivided support to ensure the project is stopped at all cost.”

Draft mining regulations insufficient to protect the deep sea – IUCN report

“Our current understanding of the deep sea does not allow us to effectively protect marine life from mining operations

“Stringent precautionary measures to protect the marine environment should be a core part of any mining regulations, yet these remain missing in action”

IUCN | 16 July 2018

Regulations under development at the International Seabed Authority (ISA) to manage deep-sea mining are insufficient to prevent irrevocable damage to marine ecosystems and a loss of unique species – many yet to be discovered, an IUCN report warns.

The report, Deep seabed mining: a rising environmental challenge, provides a comprehensive overview of deep-sea mining and its potential environmental impacts. The report was launched today, coinciding with the 24th session of the ISA, whose aim is to agree on a ‘mining code’ to regulate the exploitation of the deep seabed.

According to the report, an effective regulatory framework is needed to avoid lasting harm to the marine environment, based on high-quality environmental impact assessments and mitigation strategies. These, in turn, must be based on comprehensive baseline studies to improve the understanding of the deep sea, which remains understudied and poorly understood.

The mining code currently under development lacks sufficient knowledge of the deep sea and a thorough assessment of environmental impacts of mining operations that are necessary to ensure effective protection of deep-sea life, according to IUCN experts.

“We are operating in the dark,” says Carl Gustaf Lundin, Director of IUCN’s Global Marine and Polar Programme.

“Our current understanding of the deep sea does not allow us to effectively protect marine life from mining operations. And yet, exploration contracts are being granted even for those areas that host highly unique species. Exploitation of minerals using current technologies could potentially destroy the rich deep-sea life forever, benefitting only a few, and disregarding future generations.”

There is growing commercial interest in deep-sea mineral deposits as a result of projected rising demand for copper, aluminium, cobalt and other metals. These resources are used to produce high-tech applications, such as smartphones, and green technologies, such as electric storage batteries.

Though there is little empirical evidence of the impacts of deep-sea mining, the potential impacts are worrying. These include direct physical damage to marine habitats due to the scraping of the ocean floor by machines – similar to clearcutting a forest – and the stirring up of fine sediments on the seafloor that can smother animals and cloud the water. Additional impacts include toxic pollution due to leaks and spills, noise, vibrations and light pollution from mining equipment and surface vessels.

By May 2018, the ISA – which has the dual mandate of promoting the development of deep-sea minerals whilst ensuring that this development is not harmful to the environment – had issued 29 contracts for the exploration of the deep sea. Commercial mining in international waters is expected to begin no earlier than 2025. Exploratory mining in the national waters of Japan started in 2017, and commercial mining is predicted to occur in Papua New Guinea by 2020. 

“With regulations for commercial deep-sea mining currently under development, we are facing a unique window of opportunity to ensure that potential impacts of these operations are properly assessed, understood and publically discussed,” says Kristina Gjerde, IUCN’s Global Marine and Polar Programme senior advisor on the high seas.

“Stringent precautionary measures to protect the marine environment should be a core part of any mining regulations, yet these remain missing in action. In addition to this, the ISA’s challenging and conflicting mandate will require improved oversight by the international community to ensure marine life is adequately protected.”

Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. The area covers about 65% of the Earth’s surface and harbours a rich diversity of species – many unknown to science – which are uniquely adapted to harsh environmental conditions. It also includes unique geological features, including the Mariana Trench – the greatest depth registered in the ocean.

The 24th session of the ISA is taking place from 2 to 27 July in Kingston, Jamaica.

Te Atiawa and Taranaki Iwi fundamentally opposed to seabed mining activity

In addition to endangered Māui dolphins, other marine mammals, including fur seals, common dolphins, and orcas (killer whales) can be found in the Marine Park boundaries.

Te Atiawi iwi | 13 July 2018

Te Kotahitanga o Te Atiawa Trust and Te Kāhui o Taranaki Trust are fundamentally opposed to seabed mining activities within their tribal rohe.

Te Kotahitanga o Te Atiawa Trust and Te Kāhui o Taranaki Trust were notified of the exploration permit application by Ironsands Offshore Mining Ltd in 2016 and each iwi made a submission opposing the application back in September 2016.

Both Iwi organisations were informed of the granting of the permit on 8 June 2018, a month after the permit had been granted by New Zealand Petroleum and Minerals on 8 May 2018.

Te Kotahitanga o Te Atiawa Trust Chairperson Liana Poutu is concerned that the permit area includes a Marine Mammal Sanctuary.

“The permit has been granted inside a Marine Mammal Sanctuary which is administered and managed by the Department of Conservation.

“We find it difficult to understand how one arm of government, New Zealand Petroleum and Minerals, can cut across another arm of government and make these kinds of decisions without engagement on the issue.

“The permit area also sits inside a mineral mining exclusion zone, so although it’s only exploration at this stage the implication is that if exploration is successful there is an expectation that a mining permit will be granted in an area that excludes this activity.

“Fundamentally, the iwi and hapū of Te Atiawa are opposed to this activity,” she says.

Te Kāhui o Taranaki Trust Chairperson Leanne Horo says that the protection of our environment is a focus for Taranaki Iwi.

“Taranaki Iwi’s focus is on protecting, enhancing and sustaining the mouri of Tangaroa ki Tai.

“The Ngā Motu/Sugar Loaf Island Marine Protected Area and Tapuae Marine Reserve sit within the Te Atiawa tribal rohe and our Taranaki Iwi tribal rohe so it’s concerning to us that the permit has been granted in close proximity to these areas.

“We are launching our environmental management plan, Taiao Taiora, in the coming week which outlines our position on environmental issues.

“Taranaki Iwi is fundamentally opposed to any new mining or prospecting activity taking place within our rohe,” she says.

The permit area at its closest is 2.8km from shore, and sits almost entirely in the West Coast North Island Marine Mammal Sanctuary established in 2008. The permit area at its closest is 0.45km from the Ngā Motu/Sugar Loaf Island Marine Protected Area and at its closest is 1km from the Tapuae Marine Reserve. The permit area overlaps the Mineral Mining Exclusion Zone in two places.
