Australia mining company sorry for losing radioactive device

PERTH, Australia (AP) — A mining corporation apologized for losing a highly radioactive capsule over a 1,400-kilometer (870-mile) stretch of Western Australia, as authorities combed parts of the road looking for the tiny but dangerous substance.

The capsule was part of a device believed to have fallen off a truck while being transported between a desert mine site and the city of Perth on Jan. 10.

The truck transporting the capsule arrived at a Perth depot on Jan. 16. Emergency services were notified of the missing capsule on Jan. 25.

Western Australia emergency services have called on other Australian states and the federal government for support finding the capsule as they lack equipment. The capsule measures 8 millimeters by 6 millimeters (0.31 inches by 0.24 inches), and people have been warned it could have unknowingly become lodged in their car’s tires.

The caesium 137 ceramic source, commonly used in radiation gauges, emits dangerous amounts of radiation, equivalent of receiving 10 X-rays in an hour. It could cause skin burns and prolonged exposure could cause cancer.

The chief executive of the mining giant Rio Tinto Iron Ore, Simon Trott, on Sunday said the company was taking the incident very seriously and apologized for causing public concern.

“We recognize this is clearly very concerning and are sorry for the alarm it has caused in the Western Australian community,” Trott said. “As well as fully supporting the relevant authorities, we have launched our own investigation to understand how the capsule was lost in transit.”

The search has involved people scanning for radiation levels from the device along roads used by the trucks, with authorities indicating the entire 1,400-kilometer (870-mile) route might have to be searched.

Western Australia’s Department of Fire and Emergency Services publicly announced the capsule had gone missing on Friday, two days after they were notified by Rio Tinto.

Trott said the contractor was qualified to transport the device and it had been confirmed being on board the truck by a Geiger counter prior to leaving the mine.

Police determined the incident to be an accident and no criminal charges are likely.

Biden protects Minnesota’s Boundary Waters from mining

Comment

correction

An earlier version of this story incorrectly suggested that mining was proposed inside the Boundary Waters Canoe Area Wilderness. The proposed mining would be near the wilderness area.

The Biden administration is banning mining for 20 years in a giant watershed near Minnesota’s Boundary Waters Canoe Area Wilderness, the president’s latest effort to deliver on conservation pledges that would shape the future of America’s wild lands.

The move, announced Thursday, extends a temporary decision from a year ago to block copper, nickel and other hard-rock mining that the Trump administration had tried to greenlight near the Canadian border. Officials said they determined the potential toxic leaching from mining would be too threatening to nature, local Native American communities and a growing recreation economy.

Boundary Waters is the most heavily visited wilderness area in the country, according to the Interior Department. And Thursday’s decision will affect 225,000 acres of federal lands and waters in the Rainy River Watershed, which abuts the wilderness area northwest of Lake Superior.

It comes a day after the administration took action to protect Alaska’s Tongass National Forest, and as it faces other decisions on hotly fought over sites in Alaska and Nevada. The Biden administration has promised to set aside sacred tribal sites and to conserve 30 percent of America’s lands and waters by 2030, but has come under fire for how to balance that push with demand for oil, renewable energy and minerals.

“The Department of the Interior takes seriously our obligations to steward public lands and waters on behalf of all Americans,” Interior Secretary Deb Haaland said in a statement. “Protecting a place like Boundary Waters is key to supporting the health of the watershed and its surrounding wildlife, upholding our Tribal trust and treaty responsibilities, and boosting the local recreation economy.”

Advocates for mining in the region have said it can be a key domestic source of the materials needed for President Biden’s promised transition to cleaner energy. Twin Metals Minnesota, a subsidiary of the Chilean mining conglomerate Antofagasta, held leases there that the administration canceled last year, and has accused the administration of trying to go around the law to stop the project for political gain.

In a statement Thursday, a mining industry leader said the decision was frustrating, given the Biden administration’s stated goals on “electrification, the energy transition and supply chain security.”

“At a time when demand for minerals such as copper, nickel and cobalt are skyrocketing for use in electric vehicles and solar and wind infrastructure, the administration is withdrawing hundreds of thousands of acres of land that could provide U.S. manufacturers with plentiful sources of these same minerals,” said Rich Nolan, president and chief executive of the National Mining Association.

The administration’s environmental agenda has led to similar showdowns with oil and mining companies in Alaska and solar developers in Nevada. It faces decisions many expect within days on the Bristol Bay watershed in Alaska and 33,000 acres around the Avi Kwa Ame mountain in Nevada.

It also made a commitment to Alaskan leaders to finish an environmental review this month on ConocoPhillips’s multibillion-dollar Willow oil project, which climate activists oppose. That deadline arrives Tuesday, and the administration has signaled it may allow drilling to go forward there, within a smaller area.

Current and former administration officials think the company’s long-standing leases would be hard for the federal government to break. Such legal impediments have forced the administration to go slow on big swaths of its climate agenda and limited how far it can go to fulfill promises Biden has made to block oil drilling in the Arctic and other federal territory.

“They have had legitimate difficulties with a divided country and Congress,” said John Leshy, a law professor who served as Interior’s solicitor under President Bill Clinton and has written on federal authority to curb fossil fuel leasing. “They are exhorting people — in state government, in the private sector, at all levels — to pay more attention to conservation. I think that is generally working.”

Biden commits to honoring tribes by protecting public lands in Nevada

Administration officials did not take questions on the timing of their moves and whether there is a strategy to expedite them now. But in recent days they have emphasized they are committed to fulfilling the environmental promises Biden made at the start of his administration.

On Thursday, an Interior official noted the department had already canceled the Twin Metals leases, clearing an easier path for Haaland to order protections around the 1.1 million acres of Boundary Waters to go into effect. It had said the leases were improperly renewed under the Trump administration through an inadequate environmental analysis that had sidestepped the U.S. Forest Service, which manages the surface area.

Senior officials at the department see the wilderness there as a unique place, “irreplaceable” and easily damaged because of the immense and fragile connections between all the waterways that pockmark the region. In 2021, the Biden administration launched a scientific analysis, which found mining could cause irreparable damage to the region’s nature and culture, officials said Thursday. It found several examples in the last decade where containment efforts failed and other leaks from mines in the region caused such damage, an Agriculture Department official said.

Each year, Boundary Waters attracts roughly 150,000 Boy Scouts and other visitors looking to canoe, fish and connect with nature. The glaciers that gouged the region over the past 2 million years left behind a rugged terrain that is now home to wolves, moose, bobcats, beavers, bald eagles and peregrine falcons.

“Acid pollution from sulfide mines as far away as 100 miles threaten the park’s waters and all who visit. Even small amounts of this pollution is detrimental to public health,” Christine Goepfert, campaign director for the National Parks Conservation Association, said in a statement. “Banning mining activities in the region’s prized Boundary Waters will protect the broader park ecosystem now and for years to come.”

New York sued by environmental group after approval of crypto mining facility: Report

The New York Public Service Commission (PSC) was sued by environmental activists on Jan. 13 for approving the takeover of a cryptocurrency mining facility in the state.

According to The Guardian, the state Public Service Commission (PSC) is responsible for regulating public utilities, and authorized in September 2022 the conversion of the Fortistar North power plant into a crypto mining site.

The facility is located in Tonawanda, a city less than ten miles from Niagara Falls, and was set to be taken over by the Canadian crypto mining firm Digihost.

Plaintiffs claim that the approval violates New York’s climate law of 2019. The Climate Leadership and Community Protection Act (CLCPA) sets the goal of reducing 85% in statewide emissions by 2050, and zero-emissions electricity by 2040, among other targets.

In the lawsuit, the Clean Air Coalition of Western New York and the Sierra Club are represented by the non-profit Earthjustice, claiming that the Fortistar plant was only operated during periods of high demand for electricity, such as extreme weather conditions. As a crypto mining plant, however, the site would be running 24 hours a day, generating up to 3,000% more greenhouse gas emissions.

Activists argue that the New York state must conduct environmental reviews when examining projects.

In October 2021, a letter from a group of local business requested the state to deny the power plant conversion to a crypto mining facility, claiming that:

“Proof-of-Work cryptocurrency mining uses enormous amounts of energy to power the computers needed to conduct business — should this activity expand in New York, it could drastically undermine New York’s climate goals established under the Climate Leadership and Community Protection Act.”

According to public filings, Digihost planned to convert the facility to renewable natural gas to reduce its environmental impact. The company also noted that the mining site was approved by the North Tonawanda planning commission, which performs environmental reviews before making decisions.

In August, Digihost also disclosed plans to move part of its mining rigs from New York to Alabama in an effort to lower energy costs, Cointelegraph reported.

Digihost did not immediately respond to Cointelegraph’s request for comment.

Bitcoin mining revenue lowest in two years, hash rate on the decline

The revenue earned by Bitcoin (BTC) miners fell to two-year lows owing to poor market performance and a heavier computational demand amid rising network difficulty. However, an ongoing downturn in the Bitcoin hash rate over the past month has allowed miners to recoup losses.

The total Bitcoin mining revenue — block rewards and transaction fees — in United States dollars fell down to $11.67 million, a number last seen on Nov. 2, 2020, when Bitcoin’s trading price was around $13,500.

While the current market price of around $16,500 suggests an obvious increase in mining revenue, factors including greater mining difficulty and rising energy prices contribute to lower income in dollar terms.

Adding to the above, the difficulty of mining a Bitcoin block has skyrocketed to an all-time high of almost 37 trillion — forcing Bitcoin miners to spend more energy and computational power to stay competitive.

Over the past three months, however, the hash rate of the Bitcoin network witnessed a steady decline. The hash rate stands at 225.9 exahash per second (EH/s), which fell 28.6% from its all-time of 316,7 EH/s on Oct. 31, 2022.

The hash rate is a security metric that helps protect the Bitcoin network from double-spending attacks. However, considering the grand scheme of things, temporary measures taken by the community include acquiring cheaper mining hardware and resettling in jurisdictions with low energy prices.

New York City mayor Eric Adams believes that goal to make New York a crypto hub can be combined with statewide efforts to curb environmental costs related to crypto mining.

“I’m going to work with the legislators who are in support and those who have concerns, and I believe we are going to come to a great meeting place,” said Adams while revealing that the city will work with legislators to find a balance between the crypto industry development and legislative needs.

New York governor signs law cracking down on bitcoin mining

These machines, known as mining rigs, work round the clock to find new units of cryptocurrency.

Benjamin Hall | CNBC

New York Gov. Kathy Hochul signed a law Tuesday banning certain bitcoin mining operations that run on carbon-based power sources. For the next two years, unless a proof-of-work mining company uses 100% renewable energy, it will not be allowed to expand or renew permits, and new entrants will not be allowed to come online.

“It is the first of its kind in the country,” Hochul said in a legal filing detailing her decision.

The governor added that it was a key step for New York, as the state looks to curb its carbon footprint, by cracking down on mines that use electricity from power plants that burn fossil fuels. The law also comes as the crypto industry reels from the implosion of Sam Bankman-Fried’s FTX, which was once one of the most popular and trusted names in the industry.

New York’s mining law, which passed the state assembly in late April and the state senate in June, calls for a two-year moratorium on certain cryptocurrency mining operations which use proof-of-work authentication methods to validate blockchain transactions. Proof-of-work mining, which requires sophisticated gear and a lot of electricity, is used to create bitcoin, among other tokens.

Industry insiders tell CNBC it could have a domino effect across the U.S., which is currently at the forefront of the global bitcoin mining industry, accounting for 38% of the world’s miners.

“The approval will set a dangerous precedent in determining who may or may not use power in New York State,” the Chamber of Digital Commerce wrote in a statement.

It is a sentiment echoed by Kevin Zhang of digital currency company Foundry.

“Not only is it a clear signal that New York is closed for business to bitcoin miners, it sets a dangerous precedent for singling out a particular industry to ban from energy usage,” said Zhang, Foundry’s senior vice president of mining strategy.

The net effect of this, according to Perianne Boring of the Chamber of Digital Commerce, would weaken New York’s economy by forcing businesses to take jobs elsewhere.

“This is a significant setback for the state and will stifle its future as a leader in technology and global financial services. More importantly, this decision will eliminate critical union jobs and further disenfranchise financial access to the many underbanked populations living in the Empire State,” Boring previously told CNBC.

As for timing, the law took effect after governor signed off.

The irony of banning bitcoin mining

One section of the law involves conducting a statewide study of the environmental impact of proof-of-work mining operations on New York’s ability to reach aggressive climate goals set under the Climate Leadership and Community Protection Act, which requires New York’s greenhouse gas emissions be cut by 85% by 2050.

Boring tells CNBC the recent swell of support for the ban is related to this mandate to transition to sustainable energy.

“Proof-of-work mining has the potential to lead the global transition to more sustainable energy,” Boring told CNBC’s Crypto World, pointing to the irony of the moratorium. “The bitcoin mining industry is actually leading in terms of compliance with that Act.”

The sustainable energy mix of the global bitcoin mining industry today is estimated to be just under 60%, and the Chamber of Digital Commerce has found that the sustainable electricity mix is closer to 80% for its members mining in the state of New York.

“The regulatory environment in New York will not only halt their target – carbon-based fuel proof of work mining – but will also likely discourage new, renewable-based miners from doing business with the state due to the possibility of more regulatory creep,” said John Warren, CEO of institutional-grade bitcoin mining company GEM Mining.

A third of New York’s in-state generation comes from renewables, according to the latest available data from the U.S. Energy Information Administration. New York counts its nuclear power plants toward its 100% carbon free electricity goal, and the state produces more hydroelectric power than any other state east of the Rocky Mountains.

The state also has a chilly climate, which means less energy is needed to cool down the banks of computers used in crypto mining, as well as a lot of abandoned industrial infrastructure that’s ripe for repurposing. 

At the Bitcoin 2022 conference in Miami in April, former presidential candidate and New Yorker Andrew Yang told CNBC that when he speaks to people in the industry, he has found mining operations can help develop demand for renewable energy.

“In my mind, a lot of this stuff is going to end up pushing activity to other places that might not achieve the goal of the policymakers,” said Yang.

Some in the industry aren’t waiting for the state to make a ban official before taking action.

Earlier this year, data from digital currency company Foundry showed New York’s share of the bitcoin mining network dropped from 20% to 10% in a matter of months, as miners began migrating to more crypto-friendly jurisdictions in other parts of the country.

“Our customers are being scared off from investing in New York state,” said Foundry’s Zhang.

“Even from Foundry’s deployments of $500 million in capital towards mining equipment, less than 5% has gone to New York because of the unfriendly political landscape,” continued Zhang.

The domino effect

Now that the crypto mining moratorium has been signed into law by the governor, it could have a number of follow-on effects.

Beyond potentially stifling investment in more sustainable energy sources, industry advocates tell CNBC that each of these facilities drives significant economic impact with many local vendors consisting of electricians, engineers, and construction workers. An exodus of crypto miners, according to experts, could translate to jobs and tax dollars moving out of state.

“There are many labor unions who are against this bill because it could have dire economic consequences,” said Boring. “Bitcoin mining operations are providing high-paying and high-grade, great jobs for local communities. One of our members, their average pay is $80,000 a year.”

Hochul addressed some of these concerns in her statement on Tuesday, noting that she recognized the important of “creating economic opportunity in communities that have been left behind” and that she will “continue to invest in economic development projects that create the jobs of the future.”

As Boring points out, New York is a leader when it comes to state legislation, so there is also the potential for a copycat phenomenon rippling across the country.

“Other blue states often follow the lead of New York state and this would be giving them an easy template to replicate,” said Foundry’s Zhang.

“Sure, the network will be fine — it survived a nation-state attack from China last summer — but the implications for where the technology will scale and develop in the future are massive,” continued Zhang.

However, many others in the industry think concerns over the fallout of a mining moratorium in New York are overblown.

Multiple miners told CNBC there are plenty of friendlier jurisdictions: Georgia, North Carolina, North Dakota, Texas and Wyoming have all become major mining destinations.

Texas, for example, has crypto-friendly lawmakers, a deregulated power grid with real-time spot pricing, and access to significant excess renewable energy, as well as stranded or flared natural gas. The state’s regulatory friendliness toward miners also makes the industry very predictable, according to Alex Brammer of Luxor Mining, a cryptocurrency pool built for advanced miners.

“It is a very attractive environment for miners to deploy large amounts of capital in,” he said. “The sheer number of land deals and power purchase agreements that are in various stages of negotiation is enormous.”

Canada orders three Chinese firms to exit lithium mining

  • China says Canada breaks trade and market rules
  • Chinese companies’ shares fall
  • Companies say do not expect major impact on performance

OTTAWA/BEIJING, Nov 2 (Reuters) – Canada ordered three Chinese companies on Wednesday to divest their investments in Canadian critical minerals, citing national security.

China in response accused Ottawa of using national security as a pretext and said the divestment order broke international commerce and market rules.

As countries compete to shore up reserves of materials needed for a transition to a cleaner economy, the news pushed down the Chinese companies’ shares on Thursday, although they said in stock exchange filings they did not expect a major impact on their performance.

The three ordered to divest their investments are Sinomine (Hong Kong) Rare Metals Resources Co Ltd, Chengze Lithium International Ltd, also based in Hong Kong, and Zangge Mining Investment (Chengdu) Co Ltd.

The Canadian government ordered the divestiture after “rigorous scrutiny” of foreign firms by Canada’s national security and intelligence community, Industry Minister Francois-Philippe Champagne said in a statement.

“While Canada continues to welcome foreign direct investment, we will act decisively when investments threaten our national security and our critical minerals supply chains, both at home and abroad,” Champagne said.

Sinomine was asked to sell its investment in Power Metals Corp (PWM.V), Chengze Lithium was asked to divest its investment in Lithium Chile Inc (LITH.V) and Zangge Mining required to exit Ultra Lithium Inc (ULT.V).

‘UNREASONABLE’

Chinese foreign ministry spokesperson Zhao Lijian said the Canadian government was using national security as a pretext to block normal cooperation between Chinese and Canadian companies and was damaging global supply chains.

“China urges Canada to stop the unreasonably targeting Chinese companies (in Canada) and provide (them) with a fair, impartial and non-discriminatory business environment,” Zhao told a regular news briefing, adding that Beijing would resolutely defend the legitimate rights and interests of Chinese companies

Spot lithium prices have risen by more than 200% in the last year, driven by supply constraints that are expected to endure.

Rystad Energy forcast primary lithium minerals supply to be 8.5% short of the total lithium demand 2025, compared with about 10% short of demand this year.

“The latest attitude from Ottawa underscores the global competition of critical battery minerals in light of projected EV battery demand boom,” Susan Zou, a senior analyst at Rystad Energy, said of Canada’s decision.

The share price of Sinomine Resources fell 7.8% to 86.74 yuan ($11.86) on Thursday, while Chengxin’s share price fell by as much as 4% but closed at 0.7% higher at 45.65 yuan. Zangge Mining’s share price slid 3.7% during the day before edging 1.1% up to close at 28.96 yuan.

Last week, Ottawa said it must build a resilient critical minerals supply chain with like-minded partners, as it outlined rules meant to protect the country’s critical minerals sectors from foreign state-owned companies.

“The federal government is determined to work with Canadian businesses to attract foreign direct investments from partners that share our interests and values,” Champagne said.

Canada has large deposits of critical minerals such as nickel and cobalt essential for cleaner energy and other technologies. Demand for the minerals is projected to expand in the coming decades.

Earlier this year, countries including Britain, Canada and the United States established a partnership aimed at securing the supply of critical minerals as global demand for them rises.

Mine explosion in northern Turkey kills 28 | Mining News

Eight others critically injured after a blast hundreds of metres below ground tore through a mine in Amasya.

An explosion inside a coal mine in northern Turkey killed at least 28 people, Turkish officials said, while rescuers were trying to bring dozens of others trapped inside the mine to the surface.

The blast occurred on Friday at the state-owned TTK Amasra Muessese Mudurlugu mine in the town of Amasra, in the Black Sea coastal province of Bartin.

Health Minister Fahrettin Koca said on Twitter on Friday that 28 people had lost their lives in the incident.

Eleven of the 58 rescued miners were still getting treatment in hospitals, Koca also said, adding that it was not clear how many people were still trapped due to the blast that occurred as 110 people were working inside.

Energy Minister Fatih Donmez, who went to Amasra after the blast, said a preliminary assessment indicated the explosion was likely caused by firedamp – a reference to flammable gases found in coal mines.

Interior Minister Suleyman Soylu also travelled to Amasra to coordinate the rescue operation. Soylu also would not provide a number for those still trapped.

Several rescue teams were dispatched to the area, including from neighbouring provinces, Turkey’s disaster management agency, AFAD, said.

Turkish President Recep Tayyip Erdogan said he would cancel all his other arrangements and fly to the scene of the accident on Saturday.

“Our hope is that the loss of life will not increase further, that our miners will be found alive,” Erdogan said in a tweet.

“All of our efforts are aimed in this direction.”

The explosion occurred 300 metres (985 feet) below the entrance of the mine at around 15:15 GMT, the Bartin governor’s office said.

Television images showed hundreds of people, some with tears in their eyes, congregating around a damaged white building near the entrance to the pit.

Earlier, Turkey’s Maden-Is mining workers’ union attributed the blast to a build-up of methane gas, but other officials said it was premature to draw conclusions about the cause of the accident.

In Turkey’s worst mine disaster, a total of 301 people died in 2014 in a fire inside a coal mine in the town of Soma, western Turkey.

BTC mining firm Compute North files for bankruptcy

Bitcoin (BTC) mining hosting firm Compute North has filed for chapter 11 bankruptcy, amid growing pressure on the firm due to the effects of crypto winter and rising energy costs. The firm’s CEO Dave Perrill has also stepped down but will remain on the board.

The company submitted a Chapter 11 bankruptcy filing in the U.S. Bankruptcy Court for the Southern District of Texas on Sept. 22, which is now pending before Judge David Jones.

Under a Chapter 11 filing, the firm is still able to keep its operations going as it works out a plan to repay creditors. The filing reportedly outlines that Compute North owes around $500 million to 200 creditors, while its assets are said to be worth between $100 million and $500 million.

Compute North offers large scale crypto mining hosting services and facilities, hardware and a BTC mining pool. It is one of the largest data center providers in the U.S. has big name partners in the BTC mining sector such as Compass Mining and Marathon Digital.

Both companies have come out with statements via Twitter, noting that with the information they have at this stage, their business operations will continue as normal.

“Compute North’s staff informed us today that the bankruptcy filing should not disrupt business operations. We are continuing to monitor the situation and will provide further updates as they become available,” noted Compass Mining.

The bearish performance of BTC in 2022 has had a significant impact on the mining sector this year, and in the context of Texas, rising energy costs and multiple power outages during intense heat waves haven’t helped either.

Related: Maple Finance launches $300M lending pool for Bitcoin mining firms

Bloomberg Business reporter David Pan highlighted on Twitter that Compute North may have been impacted by a costly delay to a large mining facility in Texas that it wasn’t able to monetize for months.

“Compute North’s massive 280MW mining facility in TX was supposed to run rigs in April but it couldn’t due to pending approvals. From then to later this year when it finally was able to energize the machines, Bitcoin prices had gone through multiple downward cycles, fundraising opportunities dried up and major lenders scaled back,” he wrote.

Compute North adds to a long list of crypto firms that have either fallen victim to crypto winter — or in some cases helped create it — including Voyager Digital, Three Arrows Capital, Celsius Network and BlockFi to name a few.

Major Ethereum Mining Pools Will Back ETHW Mining

A number of big Ethereum mining pools are expected to support EthereumPoW (ETHW) following the merge, the new asset’s developers confirmed today. 

According to a series of tweets from the ETHW account, major pools such as F2Pool, Poolin, and BTC.com will support ETHW mining, which is expected to commence following a planned hard fork. A few hours later, Nanopool also announced that it would also participate.

Mining pools are groups of crypto miners who share their resources so that other miners can work with them and have a better chance of processing a transaction, and thus sharing in the spoils.

Ethereum, the second-largest cryptocurrency, is moving over to proof of stake in a long-anticipated transition known as the merge. This will eliminate the need for miners, as validators will replace them in keeping the network secure and process transactions. 

It is hoped the move will make the network greener. Proof-of-work blockchains—like Bitcoin—are notoriously energy-intensive. A proof-of-stake consensus mechanism eliminates the need for industrial operations that use lots of electricity to keep the network running. 

But prominent Chinese miner Chandler Guo last month launched a campaign to oppose the merge because those who previously mined Ethereum could potentially be left with useless rigs.  

To save these operations, Guo and other developers proposed a new cryptocurrency via a hard fork which would still use proof-of-work mining. And today’s news confirms that there is wider support for the move.

“In addition to the major mining pools (F2Pool, Poolin, BTC.com, etc.) that have confirmed their support of ETHW mining, some new pools are also doing mining tests based on data from our testnet,” today’s tweet said. 

It added that the ETHW community had also partnered with backup mining pool EthwMine. 

Meanwhile, a number of major exchanges—including Coinbase and Binance—have said they would not rule out listing ETHW.

Prosecutors Say JPMorgan Traders Scammed Metals Markets by Spoofing

CHICAGO—

JPMorgan Chase

& Co.’s precious-metals traders consistently manipulated the gold and silver market over a period of seven years and lied about their conduct to regulators who investigated them, federal prosecutors said Friday.

The bank built a formidable franchise trading precious metals, but some of it was based on deception, prosecutors said at the start of a trial of two former traders and a co-worker who dealt with important hedge-fund clients. They said the traders engaged in a price-rigging strategy known as spoofing, which involved sending large, deceptive orders that fooled other traders about the state of supply and demand. The orders were often canceled before others could trade with them.

The criminal trial in Chicago is the climax of a seven-year Justice Department campaign to punish alleged spoofing in the futures markets. Prosecutors have alleged the former members of

JPMorgan’s

JPM -0.31%

precious-metals desk constituted a sort of criminal gang that carried out a yearslong conspiracy that racked up big profits for the bank.

“Day in, day out for seven years, the defendants manipulated the market so that they could make more money,” U.S. Justice Department prosecutor Lucy Jennings said. “And then they lied to cover it up.”

JPMorgan paid $920 million in 2020 to resolve regulatory and criminal charges over the conduct, which involved nine futures traders and at least two salespeople who dealt with clients such as hedge funds, according to court records. Three former traders cooperated with the Justice Department’s investigation and will testify against the three defendants: Gregg Smith and Michael Nowak, who traded precious metals; and Jeffrey Ruffo, who was their liaison to big hedge funds whose trades earned money for the bank.

SHARE YOUR THOUGHTS

How do you expect the trial to play out? Join the conversation below.

Attorneys for Messrs. Smith, Nowak and Ruffo told jurors Friday that prosecutors cherry-picked a handful of trades to concoct a misleading theory of how the men traded.

Mr. Smith canceled many orders but never used them as a ruse, defense attorney Jonathan Cogan said. He often canceled orders after he realized that high-speed trading firms, which made decisions faster than he could, jumped ahead of his orders and moved the price up or down, Mr. Cogan said.

“He did not place orders with the intent to manipulate the market, not during the snippets of time the prosecutors will focus on in this case—not ever,” Mr. Cogan said.

An attorney for Mr. Nowak, who led the precious-metals desk, said his client was a gold-options trader during the years under scrutiny. Mr. Nowak used futures mostly to limit the risk of his large options positions, attorney David Meister said, so his pay wasn’t linked to making more or less money on a futures trade.

“The stuff he’s charged with here couldn’t move the needle for Mike’s pay,” Mr. Meister said.

Mr. Smith had worked at Bear Stearns before joining JPMorgan in 2008 when the bank acquired Bear in a fire sale precipitated by the financial crisis. Mr. Nowak traded for JPMorgan in both London and New York. Mr. Ruffo worked at the bank for a decade, communicating with hedge funds that were brokerage clients and providing the desk with important market intelligence, according to prosecutors. All three have pleaded not guilty.

Prosecutors have alleged the pattern of spoofing was continuous, a claim that allowed them to charge the three men with racketeering in addition to conspiracy, attempted price manipulation, fraud, and spoofing. The conduct allegedly spanned from 2008 to 2016.

Racketeering is a charge typically reserved for criminal enterprises such as the mafia and violent gangs, although eight soybean-futures traders in Chicago were convicted of racketeering in a crackdown on cheating in the early 1990s.

U.S. District Judge Edmond E. Chang has reserved up to six weeks for the trial, although prosecutors said Friday that they could be finished presenting their case within two weeks. Judge Chang last year dismissed part of the case—several counts of bank fraud—against the defendants. Prosecutors also recently moved to drop allegations related to options trading that authorities claimed had been manipulative.

Prosecutors have alleged that JPMorgan employees already were spoofing when Mr. Smith got to the bank. They say Mr. Smith and another trader from Bear brought a new style of spoofing that was more aggressive than the simpler approach people at JPMorgan had been using, according to court records.

Spoofing became an important way to successfully execute trades for hedge-fund clients whose fees were critical to the trading desk, prosecutors said. “It was key to get the best prices for those clients, so that they keep coming back to the precious-metals desk at JPMorgan, and not another bank,” Ms. Jennings said.

Guy Petrillo, an attorney for Mr. Ruffo, said Friday his client was a reliable and honest salesman whose only role was to communicate with clients and pass their orders to traders such as Messrs. Smith and Nowak.

“There will be no reliable evidence that Jeff knew that traders were using trading tactics that he understood at the time were unlawful,” Mr. Petrillo said.

Federal prosecutors have honed a formula for going after spoofing defendants during their multiyear strike on the practice. In addition to using cooperating witnesses who said they knew the conduct was wrong, prosecutors have deployed trading charts and electronic chats to depict a sequence of trades intended to deceive others in the market. While the charts show a pattern of allegedly deceptive trading, prosecutors said the incriminating chats reveal the intent of the traders placing the orders.

Former traders at

Deutsche Bank AG

and

Bank of America Corp.

were convicted of spoofing-related crimes in 2020 and 2021, respectively.

Those trials featured chats in which some defendants boasted about spoofing.

Lawyers for Messrs. Smith, Nowak and Ruffo said there are no chats in which their clients talked about spoofing because the men didn’t engage in it.

Spoofing is a form of market manipulation outlawed by Congress in 2010. Spoofers send orders priced above or below the best prices, so they don’t immediately execute. Those orders create a false appearance of supply and demand, prosecutors say. The tactic is designed to move prices toward a level where the spoofer has placed another order he wants to trade. Once the bona fide order is filled, the spoofer cancels the deceptive orders, often causing prices to move back to where they were before the maneuver started.

Mr. Smith’s style of spoofing involved layering multiple deceptive orders at different prices and in rapid succession, according to the settlement agreement that JPMorgan struck with prosecutors two years ago. It was harder to pull off but also harder to detect, and other JPMorgan traders adopted his mode of trading, court records say.

In the earlier trials, prosecutors successfully defended their theory that spoofing constitutes a type of fraud. Some traders have argued spoofing doesn’t involve making false statements—usually a precondition for fraud—because electronic orders don’t convey any intent or promises.

The tactic can impose losses on those tricked by spoofing patterns. The government has portrayed some of Wall Street’s most sophisticated trading firms, such as Citadel Securities and Quantlab Financial, as the past victims of spoofers. In the latest trial, prosecutors also plan to call individual traders who traded for their own accounts and were harmed by spoofing.
