Explorer Victor Vescovo says deep sea mining numbers don鈥檛 add up

As the International Seabed Authority (ISA) , deep sea explorer and private equity investor Victor Vescovo flew to Kingston on Monday to make the business case against mining the ocean for valuable metals.

鈥淚 didn鈥檛 come here because I鈥檓 a raving ocean environmentalist. I鈥檓 not,鈥 Vescovo told Bloomberg Green at a side event hosted by environmental group WWF. 鈥淚鈥檓 first and foremost an industrial private equity guy. I did the math and deep sea mining just doesn鈥檛 work, as the risks are extraordinarily high.鈥

Vescovo in 2019 became the first person to venture to the deepest trenches in the world鈥檚 five oceans, including piloting a submersible nearly 7 miles down to the Challenger Deep. He is also the co-founder of Texas private equity firm Insight Equity Holdings.

The policymaking Council of the United Nations-affiliated ISA, the organization charged with regulating the nascent industry, has been meeting in Kingston for the past two weeks. It comes at a pivotal moment for seabed mining, which proponents say has the potential to become a trillion-dollar industry as the shift to electric vehicles raises demand for metals found in the deep ocean, like nickel and cobalt. But a growing number of ISA member nations are calling for a moratorium or pause due to a lack of scientific data on the ecosystems targeted for exploitation.

In a talk at the WWF event, Vescovo, sporting a gray ponytail and a black suit, said the technological and financial uncertainties of mining metals thousands of miles from shore and miles below the surface of the ocean have been grossly underestimated.

鈥淚t鈥檚 an article of faith among these mining companies that they鈥檙e going to make tons of money, that it鈥檚 鈥榡ust picking rocks up off the seafloor,鈥欌 he said. 鈥淭here鈥檚 no 鈥榡ust鈥 anything when you鈥檙e at 4,000 meters in the ocean. It is an act of God to do anything at 4,000 meters.鈥

Vescovo said he was surprised the logistical challenges had not received more attention. 鈥淓verything breaks. Everything is difficult,鈥 he told the gathering, which included ISA member state delegates. 鈥淵ou鈥檙e talking about sustained heavy mining operations in depths that exceed the depth of the Titanic.鈥

Mining has not yet commenced, but the ISA鈥檚 168 member nations (plus the European Union) are under pressure to complete regulations to allow it to proceed. On July 9, a deadline to enact regulations passed. That means the ISA is now obligated to accept license applications from companies that want to begin mining, but left unresolved is whether it has to act on any submissions before regulations are in place.

The tiny Pacific island of Nauru had triggered the deadline on behalf of The Metals Company (TMC), a Canadian-registered venture it sponsors, so it could obtain an ISA license to mine polymetallic nodules 鈥 potato-sized rocks rich in cobalt and nickel that cover the Pacific seafloor by the billions.

The Metals Company went public in a SPAC in 2021. At the time, it estimated capital costs of a single deep sea mining operation and an onshore processing plant at $10.6 billion, with annual operating costs of $1.8 billion after 2030. The company鈥檚 shares closed at $1.98 on Monday, giving it a market cap of $556 million.

Vescovo said that inflation will only add to mining鈥檚 high costs. 鈥淚n the last few years, we鈥檝e had the highest inflation rate since the 1970s so the cost structure of The Metals Company or anyone else doing deep sea mining has gone up by at least 15%, if not more for offshore services,鈥 he said. 鈥淭he capital cost of the equipment that鈥檚 going to be needed to go down there and operate has also, if you just look at the Producer Price Index, gone up by 15 to 20%, as well.鈥

Salesforce chief executive officer Marc Benioff on Tuesday called on corporations to join WWF鈥檚 campaign for a moratorium on deep sea mining. BMW, Volvo, Volkswagen and Google previously pledged not to use seabed minerals.

TMC chief executive officer Gerard Barron said in a statement that the abundance and high grade of metals in polymetallic nodules creates 鈥渧ery attractive economics.鈥

鈥淲e will happily rely on our engineering partner Allseas for subject matter expertise, as they鈥檝e been operating in the deep sea for 37 years, laying pipe in extreme, 24-7 production environments for the offshore oil and gas industry,鈥 he said. 鈥淲WF are obviously out of arguments if the best they can do at their sponsored ISA event is put Mr. Vescovo in front of the assembled crowd as their expert.鈥

Mexico鈥檚 delegate to the ISA Council, Marcelino Miranda, was at the WWF event and told Vescovo, 鈥淣obody in the Council is in favor of destroying the ocean.鈥 Miranda added, 鈥淚 wonder whether we are fighting the wrong enemy because actually the enemy right now of the ocean is global warming. Fossil fuel fuels are the real danger, not an industry that doesn鈥檛 exist yet.鈥

Vescovo acknowledged that electric vehicles are important. 鈥淏ut do you need to destroy thousands or tens of thousands of square kilometers of the deep sea floor to do it, just as an experiment to figure out if it鈥檚 going to work?鈥 he said. 鈥淚鈥檝e been down there. I鈥檝e seen the polymetallic fields and there is no way to extract polymetallic nodules from the seafloor without utterly annihilating the bottom of the seafloor. It cannot be done.鈥
