Development of deep-seabed mining rules under way

Schalk Burger | Mining Weekly

In its 2014 session, held in February, world regulatory body the International Seabed Authority’s (ISA’s) Legal and Technical Commission was preparing draft regulations for the exploitation of polymetallic nodules in three areas approved for deep-seabed exploration worldwide. The first of the awarded exploration licences will expire in 2016.

The ISA has, thus far, granted 14 of its 166 member States exploration licences in these three areas. Five other exploration plans have been approved, but have not yet been concluded in the form of a contract, while a further seven exploration plans are being considered by the ISA Legal and Technical Commission.

In one of the three deep-seabed exploration areas currently permitted by international law, China, South Korea, Germany and India are among the States prospecting for polymetallic nodules and sulphides in the Central Indian basin and the Indian Ridge, far to the south-east of South Africa.

They are part of the international seabed mining exploration projects looking for polymetallic nodules along enormous undersea ridges, vast abyssal plains and geological fault lines in the Central Indian basin of the Indian Ocean, north-east of Mauritius and Réunion; and in the Equatorial North Pacific Ocean, south-east of Hawaii. Meanwhile, exploration for polymetallic sulphides is being undertaken in the Mid-Atlantic Ridge of the Atlantic Ocean and in the Southwest Indian Ridge, south of Madagascar.

Polymetallic nodules are deposits or accretions partially buried in deep-seabed sediments that contain manganese, nickel, cobalt and copper. Polymetallic sulphides often precipitate from deep-sea hydrothermal vents found along the mid-ocean ridges and contain copper, zinc, lead, gold and silver. Deep-seabed mining licences to explore for cobalt sulphides, manganese nodules, polymetallic sulphides and cobalt-rich ferromanganese crusts have been awarded to various international mining companies.

Further, commercial companies have been granted rights by several countries, including Ghana and Papua New Guinea, to mine the seabed in their exclusive economic zones for gold, silver, zinc and copper using dredging, mining and oil and gas equipment and techniques.

In Southern African waters, diamond company De Beers, coastal mining company Panda Marine and South African State-owned Alexkor mine diamonds from the coast and seabed on the West Coast.

Off the coast of Papua New Guinea, Canadian deep-seabed miner Nautilus Minerals – the first company to receive an ISA exploration licence – found that indicated mineral resources are 7.2% copper, 5.0 g/t gold, 23 g/t silver and 0.4% zinc, while inferred mine- ral resources are 8.1% copper, 6.4 g/t gold, 34 g/t silver and 0.9% zinc.

In its technical study towards developing a regulatory framework for polymetallic nodule exploitation, the ISA reports that “the renewed interest in the potential for commercial exploitation of deep-seabed polymetallic nodules is driven by an increase in demand for metals, a rise in metal prices and a decline in the tonnage and grade of land-based nickel, copper and cobalt sulphide deposits, as well as technological advances in deep-seabed mining and processing”.

History of Seabed Mining
In the past, seabed and subsoil beyond the limits of national jurisdiction were considered unregulated territory until the United Nations declared them the common heritage of human- kind in 1970. Since the 1982 United Nations Law of the Sea, the seabed can only be subjected to mining “for the benefit of all human- kind”, in accordance with the founding charter of the ISA.

Nevertheless, the ISA states: “Seabed mining has a smaller footprint and uses a more environment-friendly process than terrestrial mining. It does not impact [on] waterways, has reduced carbon emission, as a result of limited heavy machinery with less overburden, meaning a smaller volume of nonvaluable rock is removed and disposed of before the resource is exposed.”

Seabed mining also does not require additional roads, surface ore transport systems, buildings or other permanent infrastructure that could disrupt indigenous or native populations or habitats.

However, the ISA reports that the potential impact on the marine environment includes the removal of organisms and their habitats along with the mineral deposits and the smother- ing of adjacent communities by any sediment plume that may be created. “Exploration and exploitation must be carried out with minimal environmental impact.”

Meanwhile, the ISA has funded research projects to examine the potential impact of seabed mining and how to assess and mitigate these effects. Exploitation regulations will include obligations and recommendations to reduce any potential environmental impact, the organisation states.

Regulations for limited sampling exploration in international waters include significant environmental and deep-sea chemosynthetic ecosystem monitoring and management obliga- tions. State companies conducting exploration must collect baseline environmental data during this phase and during exploitation to develop their environmental monitoring plans and to determine the environmental impact of exploitation. The data must be analysed to improve understanding of the cumulative environmental impact of all aspects of exploitation.

Analysis of the data collected in the environmental monitoring programmes during exploitation will provide important feedback to, and inform potential modification of, environ- mental monitoring plans and systems. The ISA aims to establish exploitation regulations that will be modified and improved as it receives feedback from environmental studies during exploitation.

“Because exploitation will not be a public enterprise, questions immediately emerge about how to appropriately divide both profit and risk. These, in turn, raise difficult resource rent questions about capturing windfall profits and rents in the name of social justice. Both environmental destruction and the division of rent must somehow be addressed in the eventual fiscal package,” the ISA warns.

Mining Techniques and Environmental Concerns
There are several deep-seabed mining techniques, depending on the mineralisation of the resource. Some companies use a seabed-crawler machine that pumps the mineral-bearing gravels to the surface.

Other techniques use cutting machines, similar to those used for coal mining, that cut mineral-bearing rock on the seabed before the resultant sand, gravel and silt are collected by another machine and pumped as a seawater slurry to a production support vessel on the surface. Processed materials are then returned to the deep-sea area being mined.

However, the techniques may increase turbidity of the water column in the area of exploitation and may negatively affect the filter- feeding benthic organisms living on the seabed at extreme depths.

Coastal alluvial diamond mining company Panda Marine claims that marine mining has a low environmental impact, when practised responsibly, and the disturbance of the seabed and soils release nutrients that provide an additional boost to native animal populations, especially zooplankton that can help to boost the depleted Atlantic fish stocks off the western coast of Southern Africa.

Canadian marine miner Marine Mining Corp, exploring for gold off Ghana’s coast, notes that its operations require no chemical alteration of the rocks – the sands are brought up to the surface, gold removed by gravitational separation and the remaining materials returned to the seafloor.

Marine Mining says a review of similar ope- rations around the world reports little or no environmental concerns, even off heavily popu- lated and monitored beaches, such as Florida.

“In addition, the company has been investigating existing environmental problems on the coast to see whether mining operations can be tailored to ameliorate them. Many points along the coast have been modified to suit the tourist industry, and one of the results has been coastal erosion, which now endangers a number of villages. An offshore mining project may pump offshore sands to the beach to replenish them, or gravels and boulders to buffer them,” highlights Marine Mining Corp exploration manager Michael Gipp.

De Beers Marine Mining, mining off Namibia’s coast, carries out daily environmental management at an operational level and ensures legal compliance on environmental obligations.

The ISA Marine Mining Code notes that, despite States having explicit marine environmental obligations, there is little national environmental regulation of marine mining, especially beyond the territorial sea. Further, other than the ISA’s marine environmental work related to marine minerals exploration and exploitation in the areas being explored, there is none in any marine area beyond national jurisdiction.

“By developing and promulgating the code, the marine mining industry is assuming a share of the extensive responsibilities for marine environmental protection that are assigned under international law to States. The code also enables the marine mining industry to meet the requirements for regulatory predictability and reduction of risk, including environmental regulations and risks, and in facilitating financial and operational planning,” the ISA notes.

Further, a critical problem is “high grading” that, while not allowed, is “an all too frequent practice” involving a mining operation targeting only high-grade portions of reserves to maximise profits and minimise expenses, leaving significant, but lower-grade, portions behind in their concession areas.

Therefore, the ISA says: “A ‘whole of the deposit’ approach to nodule exploitation is required that includes a comprehensive resource and reserve assessment of the proposed mining area and the adoption of a sequential mining plan that maximises reserve recovery, utilisation and metal recovery.

“Provision for periodic review and update of the mining plan must be made and performance guarantees and ‘failure to perform’ penalties, with the latter escalating over time to discourage behaviour inconsistent with approved mining plans, must be included in the regulatory framework for polymetallic nodule exploitation.”

The ISA technical study for exploitation regulations recommends a phased licensing approach to grant three-year fixed-tenure mining licences to companies, which will improve the accountability of companies throughout deep-seabed mining operations through periodic review and analysis of performance.

Proposed regulations for exploitation include granting provisional mining licences after receiving detailed bankable feasibility studies, which must be preceded by a pilot mining ope- ration to prove economic, environmental and technical analyses done during exploration.

“An application for a tenured mining licence would include the data, information, analysis and conclusions of the detailed bankable feasi- bility study and full environmental-impact assessment and proposed work plans. This will provide data, information and analysis allowing the ISA to determine whether a full-scale mining operation could be undertaken in an acceptable and minimally environmentally invasive way,” the authority concludes.

Canadian mining company plays the corporate bully game in Costa Rica


Costa Rica’s rainforests are some of the most amazing places on earth. So when a Canadian mining company wanted to put an open pit, cyanide-leach gold mine in the middle of its most pristine forest, Costa Rica didn’t just say no. They said hell, no.

So what did the mining company do? They sued Costa Rica for $100 million lost profits.

It’s the latest strategy in corporate bullying: If a country won’t let you do whatever you want, then sue them for violating “free trade.”

But Costa Rica is the tip of the iceberg. Pharmaceutical giant Eli Lilly sued Canada to increase drug prices. Philip Morris has sued Australia over cigarette warning labels. The list goes on and on — and under proposed trade agreements like the Trans-Pacific Partnership, we’ll see an explosion of these kinds of lawsuits.

But fighting corporate bullies is exactly what SumOfUs was set up to do. Using the Internet to organize, our worldwide membership has the collective power to stand up to big corporations, so countries like Costa Rica don’t have to face these corporate bullies alone.

Shortly after Infinito Gold proposed its mine, Costa Rica banned the kind of destructive open pit mining they wanted to do. And you’d think that would be the end of it — but because of a so-called free trade agreement between Canada and Costa Rica, many experts think Infinito Gold will win its lawsuit. If it do, Costa Rica will have to pay a huge sum of money just because they decided to protect their forests.

Costa Rica is just one example of a growing trend of corporations bullying sovereign governments — and it could get a lot worse because of similar trade deals like the Trans Pacific Partnership (TPP) or the Transatlantic Trade and Investment Partnership (TTIP) that could affect virtually all of Europe, Australia, Asia, and North and South America.

So we’re fighting back. First, we’re blowing the whistle every time a corporation tries to bully a nation like Costa Rica. Second, we’re organizing to block new trade deals like the TPP and TTIP.

Niuminco restarts pilot mining at Papua New Guinea gold mine

Proactive Investors

Niuminco has restarted pilot mining at its Edie Creek mine in Papua New Guinea after receiving a 10 year renewal of mining lease ML 144.

The company has also acquired a 100% interest in Exploration Licence EL 1365 that adjoins to the north and west an Exploration Licence held by Morobe Mining Joint Venture, which in turn surrounds Niuminco’s Edie Creek mining leases.

EL1365 is also south of MMJV’s Hidden Valley gold and silver mine.

Pilot mining, large scale sampling and gold production at Eddie Creek recommenced last week at the 0.9 square kilometre mining lease.

Production levels are expected to rise to between 90 ounce and 120 ounces of gold per month from 90 ounces from April 2014, up from the current rate of about 30 ounce to 40 ounces of gold per month.

In addition, the proposed Stage 2, 10 hole, 2000 metre drilling program designed to test the Karuka- Enterprise Stockwork zone and Enterpise Diatreme/Maar on this lease is also scheduled to commence in April 2014.

At the planned level of gold production (and sales), both the company’s projected operating and exploration expenditures for the next 12 months are intended to be funded from internal cash flow.

Kula Gold awarded Environmental Permit for Papua New Guinea gold project

Proactive Investors

Kula Gold has been awarded the Environmental Permit for its Woodlark Island Gold Project in Papua New Guinea.

Importantly, it clears the way for the PNG Mining Advisory Council to recommend the grant of the Mining Lease to the Mining Minister.

Woodlark Island has a 2004 JORC Resource of 2.1 million ounces of gold and an Ore Reserve of 766,000 ounces.

The 9 year Project is based around three open pit mining areas and a 1.8Mtpa gravity and carbon in leach plant.

High gravity gold and total recovery of above 90% is achievable in years 1 to 6, leading to OPEX of US$730 per ounce.

CAPEX is estimated at US$160 million and life of mine OPEX is US$812 per ounce.

Strong exploration upside has also been identified.

Canadian First Nation defeats massive mining proposal

Friends of the Nemaiah Valley celebrate as mine blocked


Fantastic news!  On Wednesday, February 26/2014, the Canadian Environmental Assessment Agency released a NO decision from Environment Minister Leona Aglukkaq in response to Taseko Mine’s second proposal for proposed “New Prosperity” open pit gold and copper mine.

“The Minister of the Environment has concluded that the New Prosperity Mine project is likely to cause significant adverse environmental effects that cannot be mitigated.  The Governor in Council has determined that those effects are not justified in the circumstances; therefore, the project may not proceed.

“In making its decision, the federal government considered the report of the independent Review Panel which conducted a rigorous review of the New Prosperity Mine project, and agreed with its conclusions about the environmental impacts of the project.”

The Review Panel in its report concluded that the New Prosperity Mine is likely to cause:

  •     significant adverse effects on water quality and fish and fish habitat;
  •     significant adverse effects on the current use of lands and resources for traditional purposes by certain Aboriginal groups, on their cultural heritage and on their archeological and historical resources;
  •     significant adverse effects on wetland and riparian (interface between land and a river or stream) ecosystems; and
  •     significant adverse cumulative effects on the regional grizzly and moose populations, unless necessary mitigation measures are effectively implemented.

Friends of the Nemaiah Valley congratulates the Minister on this decision. Too much time and energy has gone into opposing this project only to get the same results as in 2010. This project has now been rejected for the third time, twice under the Canadian Environmental Assessment Act. There is no room for another application for this wrong mine in the wrong place by the wrong proponent.  The Minister’s decision is clear and unequivocal – it’s over.

Donna Barnett, Cariboo-Chilcotin Liberal MLA says in this video clip, ” The company has spent 20 years and $100 million dollars….this cannot go on….we need to figure out ways we can go forward.”  Mines Minister Bill Bennett and Taseko’s Brian Battison should listen to that advice.

In the words of Xeni Gwet’in Chief Roger William, “We call on the Province and Taseko Mines Ltd. to acknowledge that this is the end, to pack up their tents and go home.  The company has wasted too many resources and time on a project that was first rejected in 1995.  It is time to look elsewhere and leave us in peace.  We believe TML’s investors feel the same way after funding three failed attempts to get this approved.”

The Tsilhqotin News Release quotes Chief Joe Alphonse, “Now we want to be able to move forward with other business opportunities that respect our culture.  For that reason we will be making public a Tsilhqot’in Mining Policy about how engagement in our Territory must occur.”

FONV says “Sechanalyagh” to the Tsilhqot’in people who have been steadfast in their determination to protect this special and sacred place from the infringement of this most inappropriate proposal. We also give a huge Thanks to all of our supporters and other ENGO’s across the country.  This has been a David and Goliath struggle.

What about the pre-emptive judicial review Taseko filed after the Panel’s negative report last October, contesting what they considered to be a faulty understanding of their technical submission?  The Minister’s statement is clear:  the findings of the Panel were accepted unconditionally. There would be severe adverse effects in a number of areas if the mine proceeded as proposed and, given that this is Taseko’s second and “best” proposal, there is no way the mine can proceed.  FONV is confident that this mine is now dead.

How will the province respond?  In view of Mines Minister Bennett’s unabashed and unquestioning support for the mine, in spite of clear reservations from his own Ministry, we question his authority to speak to this matter with any credibility. (A report issued by the Northwest Institute comparing the different outcomes of the environmental reviews between the province (EAO) and the federal process in 2010 addressed the independence of the Panel and how that could have affected their findings on the Fish Lake project:  “The independence of the CEAA Panel may account for some of the differences in the outcome.  Given that the EAO found no significant adverse effects to anything other than fish and fish habitat in the face of strong evidence to the contrary, the question inevitably arises as to whether the reporting relationship of the EAO to the relevant provincial ministries subtly or indirectly affects its judgement, objectivity and neutrality”.)

We now await the Supreme Court’s decision in the Tsilhqot’in title case that was heard in Ottawa last November.  We expect an equally positive outcome in that case.

Where has foreign policy gone wrong? The Asianisation of Madang

Samuel Roth | PNG Attitude

TO ALL those who have never visited Madang, here are some facts to add onto your knowledge about people and places….

The biggest Chinese investment in PNG, Ramu Nickel Mining, is found in this province.

All the stores in Madang are owned by Asians except for two: Christian Books Melanesia (owner unknown ) and Yoko Trading (a very small store owned by a Chimbu fellow). The most (seemingly) expensive building in Madang, they call it “glass house”, is owned by the Chinese state-owned MCC (China Metallurgical Group Corporation).

The biggest fishing cannery and the largest number of fishing vessels in Papua New Guinea are owned by Asians.

The vast Trans-Gogol Valley and Ramu Valley, home to virgin rainforest and tropical hardwood, is logged by Asians started by Japan New Guinea Timber (JANT) decades ago and now continued by other logging giants.

I have no intention of being racist but the list (and I could go on) is phenomenal. One wonders if there are any politicians in Madang who realise these facts and might be responsive to the plight of the vulnerable.

Foreign policy pursuits these days do not necessarily reward but offer costs that are detrimental.

Only in Madang have I seen headlines about politicians winning elections while in prison, driving on to runways to stop moving planes, driving bulldozers into settlements, and  arriving in prison for failing to control violent supporters.

In a few months’ time, Madang’s long-awaited and much-anticipated Pacific Marine Industrial Zone will commence – built by Chinese using Chinese loans for Filipino companies and their PNG cohorts to excel whatever they do best in. What’s left of Madang? And what’s left for it?

Ironically, for the first time in history, the flying foxes have deserted the tourist town for destinies and reasons known only to Mother Nature.

With good manners, they have paved way for new migrants to conquer the town under the watchful eyes of all the Matus and Kukurais, the so-called chiefs.

Only God will save Madang from Asianization but in the meantime, let us ponder on where exactly has our foreign policy gone wrong.

Compensation to be paid over major acid spill in New Caledonia


Five New Caledonian environmental groups have won nearly half a million US dollars in compensation from the Vale nickel company over a major acid spill at its plant five years ago.

The court of appeal in Noumea determined the sum after the groups last year demanded Vale pay 7.8 million US dollars for the damage.

The groups took the action after considering the original fine was too insignificant and insisting the company needed to be hit in the pocket.

They calculated the demanded sum as being the equivalent of one Pacific franc for every square centimetre affected by the spill.

Vale is yet to react to the court ruling.

Over the years, there have been several incidents at the Vale plant, the latest dating back to November when a burst effluent pipe through a World Heritage lagoon closed the plant for several weeks.

Clive Palmer PNG mine mate sacked

Rowan Callick | The Australian

CLIVE Palmer’s gas tenements in Papua New Guinea — which he has claimed to be bigger than the North West Shelf — are likely to be reviewed following yesterday’s cabinet reshuffle in Port Moresby that removed his ally William Duma from his job as petroleum and energy minister.

Prime Minister Peter O’Neill said the new minister, Nixon Duban, had been instructed to ensure that “policy and regulatory issues are immediately addressed to the satisfaction of all stakeholders”.

Three years ago, Mr Palmer flew to Port Moresby to speak at a fundraising dinner for the United Resources Party founded and led by Mr Duma, which raised $600,000 for the election campaign in 2012.

Mr Palmer, whose close connection with Mr Duma goes back at least to 2008, said: “It’s all happening in PNG. This is the promised land, and with a stable government, and support from the community, it can do anything.”

He obtained from PNG’s Petroleum and Energy Department, with strong support from Mr Duma, gas exploration tenements in and offshore from the Gulf province to the northwest of Port Moresby.

A resources expert in PNG said yesterday that such tenements were allocated without cost, but on the condition a set amount of work was conducted during a certain period — or else their control was resumed by the government. Mr Palmer — who did not respond yesterday to calls — said last August that he had already spent more than $50 million exploring his PNG leases, and that one gas field there, 12km off the coast, could be worth more than $US35 billion, rivalling Australia’s North West Shelf — with its value many times that, once in production. He said the deposit had the potential to power a city the size of Brisbane for at least 100 years.

“It won’t make much difference to my life, but it should be good for the people of PNG,” he said.

Mr Duma has stayed with Mr Palmer when visiting Brisbane. Their relationship has become politically controversial in PNG.

It is understood that Mr Duban, who was formerly police minister, has been asked by Mr O’Neill to review oil and gas exploration leases, with a view to ensuring that development is promoted as rapidly as possible.

Mr Palmer’s leases — held through Palmer Petroleum and Chinampa Exploration, of which he owns 50 per cent — are among those that will come up for assessment.

Mr Duban will take charge of PNG’s official role in the commissioning later this year of the $19bn ExxonMobil-led PNG liquefied natural gas project, and in the development of the Elk Antelope field in Gulf province recently bought by French oil giant Total from PNG-based Interoil.

Mr O’Neill also dumped higher education minister David Arore, replacing him with Delilah Gore — thus creating the first cabinet in PNG history to have more than one female minister.

Deep Sea Mining; Digging a Hole We Can’t Get Out Of

Dr. Gerry Goeden | The Epoch Times

The Deep sea angler fis-is an important predator in the abyss

The Deep sea angler fis-is an important predator in the abyss

In May, 2013 the United Nations published its first plan for deep sea mining saying companies could apply for mining licenses as soon as 2016. To date the UN’s International Seabed Authority has issued 17 exploration permits with 7 more pending.

“We are at the threshold of a new era of deep sea mining” said Michael Lodge, legal counsel for the ISA. An assessment of the Pacific Ocean has estimated more than 27 billion tonnes of rocks could be lying on its floor, including 290 million tonnes of copper and 340 million tonnes of nickel.

The extraction of the rock ‘nodules’ – small mineral-rich rocks from the seabed, has been around as a concept for decades but deep sea mining for them has only recently become viable with advancements in technology.

Deep sea mining sites are usually around active hydrothermal vents at about 1,400 – 3,700 m below the ocean’s surface. The vents pour scalding mineral rich water from deep within the Earth and create sulphide deposits. These deposits contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be separated from millions of tons of sediments and marine life.

Nodules occur in an environment called the abyssal plane. It is part of the ocean floor between about 3,000 and 6,000 metres depth existing in perpetual darkness. Incredibly, this almost unknown and strange place covers more than 50% of the Earth’s surface and would be the way an outside observer would describe our planet.

Recent oceanographic expeditions conducted by an international group of scientists from the Census of Diversity of Abyssal Marine Life (CeDAMar) have found an extremely high level of biodiversity and the abyss may be a major reservoir of animal life in the oceans. The abyss also exerts significant influence upon ocean carbon cycling, dissolution of calcium carbonate and atmospheric CO2 concentrations over timescales of 100–1000 years.

Its permanent inhabitants are able to withstand the immense pressures of the ocean depths, up to 76 megapascals (11,000 psi). These regions are also characterized by continuous cold and lack of nutrients. The abyssal zone has temperatures around 2 °C to 3 °C (35 °F to 37 °F).

In August, 2012, the Papua New Guinea Government gave the go-ahead to Nautilus Minerals to start the world’s first deep sea mining. Japan and China have also expressed interest.

Canadian firm Diamond Fields International and its joint venture partner Manafa International Trade Company of Saudi Arabia the go ahead for the Atlantis II Deeps. They plan to mine what DFI calls “one of the largest hydrothermal poly-metallic deposits in the world”. Sudan’s mining minister Kamal Abdel Latif said it had already started and “We are expecting starting production maybe 2014,” added, according to Lebanon Today. The Atlantis II Deeps is believed to contain around 1.83 million tonnes of zinc, 402,000 tonnes of copper, and 3,432 tonnes of silver.

Companies including Trans-Tasman Resources (TTR) have plans to mine the seabed off the coast of NZ’s North Island.TTR has cited surveys estimating that possibly 481 million tonnes of iron ore exist up to nine metres beneath the seabed. This will effectively turn the seabed into a giant open-cut mine.

But all that glitters is not gold!

From 2009 to 2012, Aker Wirth, in cooperation with the BGR (German Federal Institute for Geosciences and Natural Resources), developed a concept for the deep sea mining of manganese nodules combined with a profitability analysis. The study was undertaken for the German Federal Ministry of Economics and Technology. The newly-developed concept has been designed for the mining of manganese nodules from water depths of up to 6000 m.

Their system consists of two manganese nodule collectors, a transport system for conveying the material, and a specially-designed production vessel. Steffen Knodt, Vice President of Technology & Innovation at Aker Wirth, explained: “To ensure efficient mining, a continuous transportation of raw material from the collectors via risers that are several kilometres in length is required. At such water depths, this places considerable demands on the robustness of the single components.”

The huge mineral collectors will cut through the ocean floor, lift the ore to the surface, and pump millions of tons of fine muddy sediments back into the water.

The first environmental concern focuses on the destruction of abyssal marine life that is incredibly slow growing in the near freezing (2°C) waters. The huge mineral collectors will destroy most of the life they pass over leaving a barren track across the abyssal plane.

Data acquired from the abyssal North Pacific and North Atlantic led Adrian Glover and Craig Smith (2003) to suggest that deep-sea ecosystems will be affected by deep sea mining operations on decadal time scales.

In 1978, a dredge aboard the Hughes Glomar Explorer, operated by the American mining consortium Ocean Minerals Company, made a mining track at a depth of 5000 meters in the nodule fields of the CCFZ. In 2004, the French Research Institute for Exploitation of the Sea found that the mining track was still visible on the seabed. Samples taken of the superficial sediment revealed that its physical and chemical properties had not shown any recovery since the disturbance made 26 years earlier.

The second environmental issue deals with the discarded waste sediments. Sediment plumes could have the greatest impact. Plumes are caused when the tailings from mining are dumped back into the ocean, creating a cloud of fine mud floating in the water.

Near bottom plumes occur when the tailings are pumped back to the mining site. The floating particles increase the cloudiness of the water, clogging filter-feeding of organisms. Surface plumes cause a more serious problem. Depending on the size of the particles and water currents the plumes will spread over enormous areas. According to Ahnert and Borowski in Environment and Deep-Sea Mining: A Perspective, the plumes will impact on the tiny plankton by reducing light penetration and in turn alter the mid-ocean food web.

Because we know almost nothing of this strange environment that covers more than half of the planet, environmental advocacy groups such as Greenpeace argue that much of the abyss should not be mined and we must proceed with caution.

Deep sea mining is a contentious issue causing inevitable environmental damage.

Conservation experts have long warned that mining the seabed will be highly destructive and will have disastrous long-term impacts for marine life. The ISA study itself recognizes that mining will cause “inevitable environmental damage”.

A key factor in the ISA’s report is the need for environmental safeguards. The document calls for monitoring of the seabed during deep sea mining operation however critics are sceptical if activity in the ocean depths can be monitored much less policed.

Acker Wirth Company claim that “the increasing scarcity of resources coupled with the continuous rise in resource prices drive the search for new raw material deposits”. These include “precious and high-tech metals, such as manganese, cobalt, nickel, copper and gold, along with rare earths (which are important for the high-tech industry)”.

They would have us believe that they have no choice and are mining for the general good.

One of the 20th Century’s greatest leaders remarked, “Earth provides enough to satisfy every man’s needs, but not every man’s greed.” He was Mahatma Gandhi. I wonder how he would have seen the destruction of the World’s last great wilderness in exchange for the wealth of a few.

St Barbara Swings to First-Half Loss on Weak Prices, Writedowns

Rhiannon Hoyle | Wall Street Journal

Australian gold producer St Barbara Ltd.  swung to a loss in its fiscal first half amid a sharp slump in precious-metal prices and writedowns against its mines in Papua New Guinea and the Solomon Islands.

Melbourne-based St Barbara said it recorded a net loss of 87.2 million Australian dollars (US$78.6 million) in the six months through December, compared to a A$2.5 million profit in the year-earlier period. It consequently didn’t offer shareholders a midyear payout.

The company said it had been forced to write down its mines further, citing weak gold prices and a “slower than anticipated improvement in operating performance.” It reported impairment charges of A$42.1 million against its Simberi and Gold Ridge operations, acquired in its takeover of Allied Gold Ltd. in 2012.

St Barbara had already announced writedowns of around A$220.9 million at the end of its fiscal year last June.
