Next-gen electrolytes may give lithium metal batteries a boost
Researchers at the University of Tokyo and the Nagoya Institute of Technology have discovered a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries.
In a paper published in the journal Nature Energy, the scientists explain that the new mechanism, which does not depend on the traditional kinetic approach, has the potential to greatly enhance batteries’ energy density, which is the amount of energy stored relative to their weight or volume.
According to Atsuo Yamada, one of the study’s authors, lithium metal batteries are a promising technology that could meet the demands for high-energy-density storage systems. However, because of the unceasing electrolyte decomposition in these batteries, their Coulombic efficiency is low.
The Coulombic efficiency, also called the current efficiency, describes the efficiency by which electrons are transferred within the battery. This means that a battery with high Coulombic efficiency has a longer battery cycle life.
“This is the first paper to propose electrode potential and related structural features as metrics for designing lithium-metal battery electrolytes, which are extracted by introducing data science combined with computational calculations. Based on our findings, several electrolytes, which enable high Coulombic efficiency, have been easily developed,” Yamada said.
The researcher pointed out that in lithium-ion batteries, the lithium-ion moves from the positive electrode to the negative electrode through the electrolyte during charge and back when discharging. By introducing high-energy-density electrodes, the battery’s energy density can be improved. In this context, many studies have been conducted over the past decades to change the graphite negative electrode to lithium metal. However, lithium metal has a high reactivity, which reduces the electrolyte at its surface. Because of this, the lithium metal electrode shows poor Coulombic efficiency.
To overcome this problem, scientists have developed functional electrolytes and electrolyte additives that form a surface protective film. This solid electrolyte interphase has an impact on the safety and efficiency of lithium batteries. The surface protective film prevents direct contact between the electrolyte and lithium metal electrode, thereby kinetically slowing the electrolyte reduction. Yet, until now, scientists had not fully understood the correlation between the solid electrolyte interphase and Coulombic efficiency.
What is known is that the stability of the solid electrolyte interphase is improved, then it is possible to slow the electrolyte decomposition and the battery’s Coulombic efficiency is increased. But even with advanced technologies, scientists find it difficult to analyze the solid electrolyte interphase chemistry directly.
A rare strategy
The Japanese research team, however, determined that if they could upshift the oxidation-reduction potential of the lithium metal in a specific electrolyte system, they could decrease the thermodynamic driving force to reduce the electrolyte, and thus achieve higher Coulombic efficiency. This strategy has rarely been applied in developing batteries with lithium metal.
“The thermodynamic oxidation-reduction potential of lithium metal, which varies significantly depending on the electrolytes, is a simple yet overlooked factor that influences the lithium metal battery performance,” Yamada said.
He and his colleagues, thus, studied the oxidation-reduction potential of lithium metal in 74 types of electrolytes. They also introduced a compound called ferrocene into all the electrolytes as an IUPAC (International Union of Pure and Applied Chemistry)-recommended internal standard for electrode potentials.
Following the analyses of their tests, the team proved that there is a correlation between the oxidation-reduction potential of lithium metal and Coulombic efficiency. In fact, they obtained a high Coulombic efficiency with the upshifted oxidation-reduction potential of lithium metal.
Looking ahead to future work, the researchers say they want to unveil the rational mechanism behind the oxidation-reduction potential shift in more detail.
“We will design the electrolyte guaranteeing a Coulombic efficiency greater than 99.95%. The Coulombic efficiency of lithium metal is less than 99%, even with advanced electrolytes. However, at least 99.95% is required for the commercialization of lithium metal-based batteries,” Yamada said.

PureGold Mining seeks creditor protection
Canadian precious metals miner PureGold Mining (TSX-V: PGM)(LON: PUR) has applied for an initial order for creditor protection from the Supreme Court of British Columbia, having considered its cash position, debt repayments and forecast revenue.
The cash-strapped miner kicked off in July a corporate review that sought to decide whether to sell the company, merge with a peer, divest its flagship gold mine in Ontario, or find other long-term financing options.
PureGold had to place its namesake mine under care and maintenance last week, as it failed to secure funds to keep operations going, despite increasing production and cash flow.
The Vancouver-based firm said the initial order seeks a stay of creditor claims and proceedings and authorization to borrow under an interim financing credit facility from its lending partner, Sprott Private Resource Lending II. It also comprises the appointment of KSV Restructuring as court-appointed company monitor.
While under creditor protection, PureGold would consider all available transactional and restructuring options with a goal of maximizing value for the company and its stakeholders, the TSX-V- and LSE-listed company said.
The PureGold mine, in Red Lake, will remain on care and maintenance and the management of the company will remain responsible for day-to-day operations, under the oversight of KSV.
The company poured first gold at PureGold mine by the end of 2020 and announced the start of commercial production in August 2021. The operation, however, has struggled to consistently produce at its nameplate capacity of 800 tonnes a day, despite mill upgrades that intended to increase capacity to 1,000 tonnes a day.
The miner noted the operation has also failed to achieve consistent positive site-level cash flow and expected additional funding had not materialized.
Construction delays, bad scheduling, problems with equipment, and “strategic misalignments, were quoted by the miner to explain production shortfalls. The mounting issues triggered a change in leadership early this year.

Scientists to look at the role of supernovae as element-makers
A researcher at Virginia Tech College of Science’s Department of Physics began using NASA’s James Webb Space Telescope to collect data on the presence of heavy elements in exploding dying stars, or supernovae.
As James Webb’s Baltimore-based mission operations center relays commands to the distant telescope to gather observations on the supernovae targeted by Chris Ashall, his team at Virginia Tech will study the collected data alongside more than 30 other scientists from around the world as part of the Mid-Infrared Supernova Collaboration.
“Pretty much everything around us comes from dying stars,” Ashall said in a media statement. “We’re made of stardust. Being able to study that fact—what we’re made out of—in detail, and to understand where the elements around us come from, is truly amazing.”
Stars produce heavy elements through the process of stellar nucleosynthesis. As stars burn, die, and explode, thermonuclear reactions take place inside them.
Supernovae are one of the highest-temperature and highest-density places in the universe. The material in stars burns and burns to form heavier and heavier elements, from hydrogen to helium, helium to carbon, carbon to oxygen, and so forth, all the way through the Periodic Table to iron.
When the stars finally explode, they throw all of this material back out into the universe at speeds up to 30% of the speed of light to make the next generation of stars and planets. “That’s how the planet and everything around us can have all of these heavy elements,” Ashall said. “They were made in dying stars.”
It’s widely accepted that most of the heavy elements in the universe are made by way of stellar nucleosynthesis, but Ashall wants to know more—to trace particular elements to the varieties of supernovae out there and to measure at what levels those elements are made by the stars.
Looking for manganese, chromium, cobalt and nickel
In his first project, the scientist will look for elements commonly found on earth, such as manganese, chromium, cobalt, and nickel, by focusing the James Webb Telescope on one supernova in particular: a third-generation white dwarf titled SN2021aefx, which exploded a year ago in the spiral galaxy NGC1566, also known as the Spanish Dancer.
Ashall will use the telescope to collect imaging and spectroscopy data on elements inside SN2021aefx. Spectroscopy involves looking at spectra produced by a material when it interacts with or emits light by breaking the light into its component colours, per NASA.
“Spectroscopy tells us about different elemental lines,” the researcher said. “If there’s a line, we know the element is there.”
Ashall’s second project will focus on detecting carbon monoxide and silicon monoxide, also building blocks for life in the universe, in core-collapse supernovae.
Core-collapse supernovae are massive dying stars more than eight times the mass of our sun. When these stars die, they collapse in on themselves and make an explosion more than 100 billion times brighter than the sun.
Using the observations made by the James Webb Space Telescope, Ashall will work to not only source heavy elements but to investigate when they were ejected by the exploding supernova.
“When we measure these lines, we can figure out velocities of the explosion,” Ashall said. “So then we’ll understand how fast these elements are thrown out into the universe.”
Starting with the single type Ia supernova, Ashall hopes to build a sample of different varieties of supernovae to produce meaningful statistics on their role as element-makers.
“If we don’t find those elements coming from supernovae, then we have to reassess what we know about how stars die and how these elements are released into the universe,” the scientist said.

Researchers develop Play-Doh-like material that conducts electricity like metal
Researchers at the University of Chicago have discovered a way to create a material that can be made like a plastic, but conducts electricity like a metal.
In a paper published in the journal Nature, the scientists explain that even though the molecular fragments of the material are jumbled and disordered, it can still conduct electricity extremely well. This goes against all of the known rules about conductivity.
“In principle, this opens up the design of a whole new class of materials that conduct electricity, are easy to shape, and are very robust in everyday conditions,” John Anderson, senior author of the study, said in a media statement.
Anderson explained that by far, the oldest and largest group of conductors are metals: copper, gold, aluminum, and so on. Then, about 50 years ago, scientists were able to create conductors made out of organic materials by using a chemical treatment known as ‘doping,’ which sprinkles in different atoms or electrons through the material.
Using this technique has proven advantageous because materials become more flexible and easier to process than traditional metals. The issue that they face, however, is that they aren’t very stable; they can lose their conductivity if exposed to moisture or if the temperature gets too high.
Nickel atoms
In terms of their basic characteristics, both organic and traditional metallic conductors share a commonality: They are made up of straight, closely packed rows of atoms or molecules. This means that electrons can easily flow through the material, much like cars on a highway. In fact, scientists thought a material had to have these straight, orderly rows in order to conduct electricity efficiently.
But recently, the study’s lead author Jiaze Xie began experimenting with nickel atoms, which he strung like pearls into a string of molecular beads made of carbon and sulphur and began testing.
To his astonishment, the material easily and strongly conducted electricity. What’s more, it was very stable.
“We heated it, chilled it, exposed it to air and humidity, and even dripped acid and base on it, and nothing happened,” Xie said. “That is enormously helpful for a device that has to function in the real world.”
But to Xie and his colleagues, the most striking thing was that the molecular structure of the material was disordered.
“From a fundamental picture, that should not be able to be a metal,” Anderson said. “There isn’t a solid theory to explain this.”
Xie, Anderson and their lab worked with other scientists to try to understand how the material can conduct electricity. After tests, simulations, and theoretical work, they think that the material forms layers like sheets in a lasagna. Even if the sheets rotate sideways, no longer forming a neat lasagna stack, electrons can still move horizontally or vertically—as long as the pieces touch.
The end result is unprecedented for a conductive material.
“It’s almost like conductive Play-Doh—you can smush it into place and it conducts electricity,” Anderson said.
The scientists are excited because the discovery suggests a fundamentally new design principle for electronics. For example, metals usually have to be melted in order to be made into the right shape for a chip or device, which limits what can be done with them, since other components of the device have to be able to withstand the heat needed to process these materials. The new material has no such restriction because it can be made at room temperature.

Coupling energy production with lithium extraction may lower cost of geothermal development – research
Recent research by a team at the Pacific Northwest National Laboratory (PNNL) shows that coupling energy production with lithium extraction could substantially lower the cost of geothermal development and boost plant profitability.
Zeroing in on the Salton Sea, the PNNL group took a close look at how various finance, policy, and technology scenarios could affect the time to profitability and projected profits of geothermal plants in the region. Shorter permitting timelines, reduced construction costs, and government subsidization could all increase geothermal viability, but co-location with lithium extraction was shown to have the greatest potential to lower barriers and encourage successful future geothermal development.
“Geothermal development has been stagnant for the last 30 years due to economic and logistic constraints but coupling it with lithium extraction could make plants more profitable, faster,” Dave Goodman, one of the scientists involved in the study, said in a media statement.
Goodman explained that in geothermal energy production, brine is heated by super-hot rock deep underground. When the brine is moved to the surface, it cools rapidly, producing steam that turns turbines and generates energy. Then, the brine is returned to the ground, continuing the cycle.
The scientist pointed out that the United States has the largest known geothermal resource in the world, with an estimated potential to provide up to 10% of the total US electricity capacity.
But geothermal resources at the Salton Sea don’t just offer renewable energy—the brine is full of minerals, including valuable metals like lithium, that could be extracted with the right technologies.
Currently, very little lithium is produced in the country, which imports most of the battery metal from Australia, Chile, and China. Thus, creating a sustainable domestic supply of lithium has led researchers and developers to get creative about how and where to extract more lithium.
“There’s a lot of optimism around future lithium extraction technologies,” Patrick Mirick, another scientist involved in the project, said. “Our research shows that if these technologies work as planned, they’ll be a financial game changer for the geothermal industry.”
Techno-economic analysis
To determine just how much co-locating lithium extraction at geothermal power plants could potentially change the industry, the PNNL group conducted a techno-economic analysis to project plant profitability over time in the Salton Sea.
Looking at different timelines, financing options, and technologies, the researchers projected that incorporating lithium extraction would result in the biggest potential impacts for geothermal plants: decreasing the cost of electricity generation, shortening the time to plant profitability, and increasing net profits. Such changes would remove significant barriers to development in the geothermal industry.
In 2020, the California Energy Commission (CEC) estimated that the subsurface rock in the southern Salton Sea region contained subsurface brine with the potential to supply 40% of the world’s lithium demand and generate over $7 billion in annual revenue. The potential of this region to produce clean energy and lithium is so promising that the CEC set up the Lithium Valley Commission to further investigate opportunities in this area.
In addition to making financial sense, the PNNL group noted that extracting lithium—and other valuable metals and minerals—from geothermal brine avoids many of the environmental and social concerns associated with current lithium extraction methods.
Because the brine is already brought to the surface to support geothermal development, the additional impacts of adding lithium extraction to a geothermal plant are minimal and expected to have fewer environmental impacts than traditional hard rock mining while providing critical minerals for a clean energy future.

Studying unintended consequences of mercury mitigation strategies key to artisanal mining sustainability goals
A recent study published in the journal Resources, Conservation and Recycling, states that when dealing with the issue of mercury in artisanal and small-scale gold mining (ASGM), it is important to avoid focusing excessively on a few outcome measures while ignoring the totality of the effects of the interventions proposed.
This conclusion is the result of an analysis carried out by researchers at Japan’s Ritsumeikan University and the University of Tokyo, who looked at the potential unintended consequences of the main strategies proposed to minimize mercury use and emissions in artisanal and small-scale gold mining (ASGM) under the Minamata Convention.
Launched in 2017, the Minamata Convention (MC) aims to restrict and limit the use and trade of mercury – which is considered a highly toxic pollutant – through a series of mid- and long-term strategies. In particular, Article 7 of the treaty deals with the problem of mercury in ASGM, stating that party members have an obligation to minimize or outright eliminate mercury use and emissions in such activities within their borders.
Although concrete intervention strategies have been suggested and implemented with some success in this regard, scientists have paid little attention to the side effects that these measures can have. To tackle this issue, the Japanese researchers examined the effects of the three primary mitigating strategies proposed by the UN’s Environment Programme, namely, the practice of concentrate amalgamation, using a mercury retort, and using cyanide instead of mercury to extract gold.
The first strategy involves concentrating the gold ore as much as possible before adding mercury using tools such as a centrifuge or a floatation tank. This way, the total amount of mercury needed per gram of gold is greatly reduced. The second strategy is based on the use of low-cost devices called retorts, which are designed to trap harmful mercury vapours and turn them back into liquid mercury. The third strategy involves outright replacing mercury with cyanide-based processes for gold mining.
Using mathematical models and data from 80 countries with ASGM published in the UN’s Global Mercury Assessment 2018, the researchers projected the effects of these intervention strategies on global mercury use and emissions up to 2050, as well as their associated unintended consequences.
Unintended consequences
One of the main conclusions of their analysis was that the first intervention strategy—concentrate amalgamation—does not seem to lead to a significant reduction in mercury use nor in emissions, though it does not have significant negative side effects.
In contrast, the use of retorts can considerably reduce the amount of global mercury emissions. However, using retorts also means that there would be a great surge in the amount of liquid mercury that has to be properly managed as a waste product, therefore creating a new problem on its own.
Finally, the cyanidation approach does lead to an immense reduction in mercury use and emissions but replaces them with cyanide emissions, which are also quite dangerous.
“The findings of our study quantitatively identified the extent of the problems inadvertently created by different intervention strategies,” Shoki Kosai, lead author of the paper, said in a media statement. “Our results clearly show that the more effective measures for reducing mercury use and emissions require the most attention with regard to their unintended consequences.”
Kosai and his colleagues hope that the estimates they’ve presented are used to identify and develop the required actions needed to improve each intervention strategy, with the ultimate goal being an environmentally friendlier artisanal and small-scale gold mining sector.
“There are about 10 to 19 million people involved in ASGM activities in Asia, Africa, and Central and South America. Our efforts will assist in mitigating health damages caused by the absorption of mercury vapours in the future,” Eiji Yamasue, co-author of the study, said.

Pure Gold places Ontario mine on care and maintenance due to cash constraints
Pure Gold Mining (TSXV: PGM; LSE: PUR) is suspending operations at its flagship mine in Ontario and placing it on care and maintenance, as the mine has yet to achieve consistent positive site-level cash flow to alleviate the company’s financial problems.
Currently, Pure Gold has a cash balance of approximately C$2 million and a net working capital deficit of about C$13 million, excluding amounts owing under the company’s debt obligations to Sprott Resource Lending Corp.
In its second quarter financial report, Pure Gold had booked an operating loss of C$18.5 million despite a 30% reduction in costs compared to the first quarter. Net loss and comprehensive loss totalled C$20.8 million. Both figures were higher than their comparative periods in 2021.
The miner had previously noted that it expected at least some additional funding in 2022 to come from the exercise of warrants issued in conjunction with its May 2022 financing. However, the warrants are currently priced to be exercised at C$0.18 per share, and given current market conditions, it no longer expects to receive any proceeds from warrant exercises prior to their expiry on November 25-27.
To date, none of the warrants have been exercised, and the company has so far been unable to obtain alternative outside financing in order to continue operations, complete its ongoing pre-feasibility study (PFS) and life-of-mine plan, and continue its ongoing strategic review process.
If additional outside financing is not obtained in the short term, Pure Gold says it will not be able to meet its debt obligations as they become due, which would result in a default.
Pure Gold has also withdrawn its production guidance for the fourth quarter of 2022, which was previously set at 9,000-12,500 oz. The company had achieved its Q3 guidance, producing just over 9,000 oz.
The Pure Gold mine, located in Red Lake, Ontario, first began production in 2021 after the successful construction of an 800 t/d underground mine and processing facility.
Shares of Pure Gold Mining continued to plunge on the latest development. The stock crashed 83% to trade at C$0.02 a share by 11:30 ET Monday, compared to a 52-week high of C$1.08 on November 12, 2021. The company’s market value now sits at C$14.6 million.

Scientists want to produce cosmic mineral to replace REEs in industrial magnets
Engineers at Northeastern University have patented a process to accelerate the production of a mineral known as tetrataenite, whose magnetic properties make it a leading candidate to replace magnets made of rare earths.
Tetrataenite is not found in nature—at least, not on earth. It is only found in meteorites. This means that making the cosmic mineral requires manipulating the atomic structures of its iron and nickel components by arranging them into a crystal structure that resembles tetrataenite, thus speeding up a natural process that would take millions of years on our planet.
“The iron and nickel atoms have to rearrange themselves. And nature will do it, but it will take millions of years to do,” Laura Lewis, one of the researchers involved in the study, said in a media statement. “So if we can do it in industrially relevant time scales, we will have a nice new addition to the permanent magnet portfolio.”
According to Lewis, decoupling the scarce materials from magnet production not only provides sorely needed supply chain relief—there simply aren’t enough magnets to meet the world’s energy needs—but it will help rebalance geopolitical tensions by easing the US dependence on Chinese rare earths.
China controls close to 80% of the world’s rare earths supply, while global demand for REE magnets is expected to reach $37 billion by 2027.
In Lewis’ view, however, having a single source of REEs is not the only issue at hand.
“It’s beyond just scarcity,” she said. “Because the methods necessary to process the ore that comes out of the earth are really environmentally hazardous—I would say even damaging. And for many decades, China not only has had a large supply of these rare earths but the means and will to produce them.”
The researcher mentioned that while China has been using rare earths to meet the needs of its own green revolution, its virtual monopoly presents an obstacle to other nations looking to get their hands on the materials.
Discovering nature’s rules
Industrial permanent magnets are used to transfer energy from mechanical to electrical sources. The list of technologies that rely on magnetic flux includes electric cars, wind turbines, computer hard drives, speakers, and military radars, among other devices and applications.
“They’re absolutely everywhere,” Lewis pointed out. “Once you start pulling things apart, you’re going to find them everywhere.”
She and her team are, therefore, tasked with “discovering nature’s rules for the creation of competitive magnetic materials comprised of non-critical elements.”
Lewis is also a delegate to two US technical advisory groups representing the American National Standards Institute in the International Standards Organization. The advisory groups she contributes to focus on managing the supply chains for critical elements linked not just to rare earths, but also materials such as lithium that are used in both household and industrial technologies.
“I’ve been meeting with my counterparts in China, Japan, Korea, Australia, and Europe to figure out how to fix these supply chains,” Lewis said.

Chilean mines’ demand for clean energy solutions could be met by local businesses – report
A recent study conducted by the Santa María Technical University, the National Piloting Center and consultancy agency Phibrand showed that there is a big demand from miners operating in Chile for solutions that allow them to join the clean energy transition.
According to the report, such demand could be met by local companies as long as they ramp up the production of green fuels and their manufacturing capabilities when it comes to electrifying mining fleets.
The study, which involved a series of interviews with suppliers, industry experts and representatives from the main mining companies operating in the country, revealed that the conversion of small and medium-sized equipment and machinery is a potential business opportunity and is an efficient way to push the country towards a greener future.
Speaking at a panel discussion during the presentation of the report, Gonzalo Ramírez, one of Codelco’s electromobility experts, said that mining companies, and Codelco in particular, must speed up their decarbonization efforts by dealing with challenges such as renewing electricity contracts, achieving a 100% electric underground mining, reducing emissions in their pits by at least 10%, and promoting a green hydrogen market for mining applications.
“We see these changes as disruptive innovations in the energy supply chain of our operations,” Ramírez said.
The study also identified barriers that would hinder the development of the opportunities that the industry requires for the energy transition.
Among such obstacles are the lack of spaces for piloting and validating new technologies; low levels of technological adoption; a gap between the goal of contributing to reducing emissions and the investments needed to do so; a lack of incentives for the mining sector to invest in manufacturing or converting equipment, and the need for training and new professional skills.
“The purchasing power, the will and the interest exist. But these technologies must materialize today, in the early stages of the energy transition,” Cristian Mansilla, general manager at Phibrand, said during the panel discussion. “A quick conversion to electromobility and synthetic fuels, which includes both the production and distribution of these solutions, is key. If companies don’t take the step now, they won’t be able to compete in the market in the future.”

Lithium-oxygen batteries one step closer to moving out of the lab
Researchers at the Chinese Academy of Sciences have fabricated two-dimensional Mn3O4 nanosheets with dominant crystal planes on graphene (Mn3O4 NS/G) as efficient oxygen catalysts for lithium-oxygen batteries, achieving ultrahigh capacity and long-term stability.
In a study published in the journal ACS Catalysis, the scientists explain that Li-O2 batteries are among the most promising devices for the green energy transition due to their high theoretical energy density. However, the poor catalytic performance of its air cathode has impeded its commercialization.
This is why – they say – it is crucial to design oxygen catalysts with well-defined shapes and high-activity crystal facets that can effectively regulate the oxygen reduction reaction and the oxygen evolution reaction at the three-phase interfaces. The problem is that this process remains challenging.
Through their testing, the researchers noticed that the Mn3O4 NS/G with the facets (101) and enriched oxygen vacancies offered a lower charge overpotential of 0.86 V than that of Mn3O4 nanoparticles on graphene (1.15 V).
Moreover, the Mn3O4 NS/G cathode exhibited long-term stability over 1,300 hours and ultrahigh specific capacity up to 35,583 mAh/g at 200 mA/g, outperforming most Mn-based oxides for Li-O2 batteries previously studied.
“This work may provide clues for engineering Mn-based materials with a defined crystal facet for high-performance Li-O2 batteries,” Wu Zhongshuai, co-lead author of the research, said in a media statement.

Coal ash pollution affecting lakes for longer than previously thought
Researchers at Duke University and Appalachian State University ran an analysis of sediments from five North Carolina lakes near coal-burning power plants and found that coal ash pollution of surface waters has been more persistent and widespread than was previously thought.
The findings show that large quantities of coal ash have been transferred and deposited in lake sediments since the beginning of coal operations in the state.
“The bottom sediments of a lake represent a complete history of what has fallen into the lake water and settled to the bottom,” Avner Vengosh, one of the scientists involved in the project, said in a media statement. “Using our age-dating methods, we were able to go back in time, in some cases even before the coal plant was built, and reconstruct the history of the lakes.”
Coal ash is the residual material from burning coal to generate electricity, and is known to contain lead, chromium, cadmium, mercury, arsenic, selenium and molybdenum, many of which have been tied to human cancers and other health effects.
According to Vengosh, the contaminants are not locked into the lake sediments. A chemical analysis of the pore water within the lake sediments indicated the metals leached out from the buried coal ash and could enter the aquatic food chain.
“These are recreational lakes,” said Zhen Wang, who led the study published in Environmental Science & Technology. “Some of them, like Hyco Lake, were originally built for the coal plant, but over the years, it has become very desirable real estate where people build their dream homes. It looks very pristine and beautiful, but if you dig in, you find piles of toxic coal ash.”
The five lakes in the study, however, were created for nearby coal plants: Hyco Lake and Mayo Lake, north of Durham in Person County; Belews Lake, northwest of Greensboro in Rockingham, Forsyth and Stokes Counties; Mountain Island Lake, northwest of Charlotte in Mecklenburg County; and Lake Sutton, northwest of Wilmington in Brunswick County. For comparison, the researchers also sampled Lake Waccamaw in Columbus County, west of Wilmington, a natural lake that was dammed in 1926 so it wouldn’t dry out during droughts.
Different types of coal ash
By looking at the microscope, the researchers were able to identify the different types of coal ash that were deposited over time in the lakes.
They noticed that at several of the sites, coal ash was initially dumped into the nearby lake. Over time, when the Clean Air Act was enforced and scrubbers were added to the coal plant smokestacks to catch fine particulates, the deposited coal ash changed and included higher proportions of small particles.
The tiny particles, however, contain the highest concentrations of toxic elements, which made contamination worse for the lakes.
The study authors suggest the coal ash could reach lakes by three possible routes: Atmospheric emissions of coal ash, particularly before the installation of the scrubbers, settled in nearby lands and was washed back into the lake by its watershed; climate events like tropical storms and hurricanes flooded and flushed the nearby coal ash impoundments to overflow into the nearby lakes, and ordinary flows of effluents from the coal ash ponds reached the lake as part of their routine operation.
“While previously we thought that lakes and groundwater are being contaminated by leaking or effluents discharge from of coal ash ponds, the new findings indicate that we have underestimated the environmental impact of coal ash,” Vengosh said. “We thought that the majority of the coal ash is restricted to coal ash ponds and landfills. Now we see it’s already in the open environment.”
The scientist and his colleagues warn that this is a much larger problem and given climate change it will only grow worse.
“We did a very detailed examination of five lakes, but there are numerous lakes or open water reservoirs next to coal plants not only in North Carolina but all over the country,” Vengosh said. “The phenomenon that we discovered probably applies to many other sites across the US and all of them are going to be vulnerable to more extreme weather events and flooding that we know is coming from global warming.”

Stillwater Critical enjoys ‘sweet spot’ in Montana’s Lower Stillwater PGMs Complex
Stillwater Critical Minerals (TSXV: PGE; US-OTC: PGEZF) is “rewriting the book” on the Lower Stillwater Igneous Complex in Montana, says president and CEO, Michael Rowley.
The company’s evaluation of the flagship Stillwater West project continues to confirm more parallels to South Africa’s Bushveld Igneous Complex, and positions the company as the second-largest landholder in the Stillwater Complex, with a 100%-owned position next to Sibanye-Stillwater’s (JSE: SSW; NYSE: SBSW) PGE mines in south-central Montana.
“Given global geopolitical tension on several fronts, the world is increasingly looking towards North America and other first-world jurisdictions to supply the critical minerals such as PGMs, nickel, cobalt, copper and gold the modern economy requires,” Rowley said in an interview with The Northern Miner.
“With Stillwater West, we’re at a remarkable sweet spot. It’s got a lot of data, a supportive U.S. Geological Survey backing, but it’s, remarkably, not well understood,” Rowley said. “We’re rewriting the book on the Lower Stillwater Complex, quite literally. And there’s a lot of potential there. It’s a big and well-mineralized system.”
Since acquiring the project in 2017, Stillwater Critical, then known as Group 10 Metals, has focused on the potential for Stillwater West to host large-scale Platreef-style nickel and copper sulphide deposits, enriched in palladium, platinum, rhodium, gold and cobalt.
The company’s work to date has confirmed Stillwater West’s location in the Stillwater Igneous Complex relative to Sibanye-Stillwater’s productive J-M Reef deposits as comparable to Ivanhoe Mines’ (TSX: IVN; US-OTC: IVPAF) Platreef deposit and Anglo American’s (LSE: AAL) PGE-nickel-copper Mogalakwena mine in a similar geologic setting in the U.S.
Stillwater’s most important milestone yet was the release in October 2021 of an initial inferred resource estimate encompassing five Platreef-style deposits totalling 1.1 billion lb. of nickel, copper and cobalt, and 2.4 million ounces of palladium, platinum, rhodium and gold. The constrained model totals 157 million inferred tonnes averaging 0.45% total nickel-equivalent (or 1.2 grams palladium-equivalent per tonne), using a 0.2% nickel-equivalent cut-off.
Since then, Stillwater Critical has reported several wide, high-grade battery and precious metal intercepts in wide step-outs from known mineralization in expansion drilling.

Endeavour Mining starts building Lafigué gold mine in Côte d’Ivoire
Endeavour Mining (TSX, LON: EDV) has kicked off construction at its 80%-owned Lafigué gold project in Côte d’Ivoire, which is expected to begin production in the third quarter of 2024.
The $448 million project, located on the Fetekro property, adds to a long list of activities the London-based miner has undertaken this year. These include the Sabodala-Massawa expansion project in Senegal, and the construction of a recyanidation circuit at its cornerstone Ity operation, also in in Côte d’Ivoire.
Based on the just finished definitive feasibility study (DFS), Lafigué will produce in average 203,000 ounces of gold a year, at an all-in sustaining cost of $871 per ounce over a 12.8-year mine life.
The company’s chief executive, Sébastien de Montessus, said the mine would be “a cornerstone” for the company, allowing it to enhance the group’s geographical diversification.
“We are ideally positioned to launch the construction of Lafigué, given our net cash position, the continued strong performance of our operations, and our success in de-risking the Sabadola-Massawa expansion with a significant portion of the capital already committed on-budget,” he said in the statement.
De Montessus added the company was already seeing reduced inflationary pressures and favourable foreign exchange rates, compared to earlier in the year.
Executive VP for exploration and growth, Patrick Bouisset, said the Lafigué discovery was an example of how the company creates value.
“For a modest exploration investment of $31-million, which represents a discovery cost of $12/oz, we have added a new cornerstone asset to our portfolio. To continue to source our projects organically, we have increased our greenfield exploration efforts, which, over recent months, have resulted in significant success at our Tanda-Iguela property in Côte d’Ivoire, where we expect to publish a maiden resource later this year.”
The company has forecast full year production of between1.32 million and 1.4 million ounces of gold for this year at all-in sustaining costs of $880 to $930 per ounce.

Turquoise Hill’s fifth largest investor to reject Rio Tinto’s takeover bid
Sailingstone Capital Partners, the fifth-biggest investor in Turquoise Hill Resources (TSX: TQR) said on Friday it will vote against Rio Tinto’s (ASX, LON: RIO) intended $3.3 billion takeover of the Canadian miner, in a shareholder meeting on Nov. 1.
The activist investor said that Rio’s bid not only undervalues the target, but it also intends to take advantage of the “material governance failures” created by independent directors of both mining companies over the last decade.
Sailingstone, a US-based fund manager specializing in resources companies that has a 2.2% stake in Turquoise Hill, had already said it considered the offer too low and “opportunistic”.
Rio Tinto announced on Sep.1 it had reached an agreement after six months of takeover talks to buy the 49% of the Canadian miner it didn’t already own for a figure about 20% higher than the original $2.7 billion bid, made in August.
The deal would give the global miner a 66% stake in the giant Oyu Tolgoi mine in Mongolia, one of the world’s largest known copper and gold deposits. The remaining 34% is owned by the Mongolian government.
Rio Tinto has had a rocky relationship with the Quebec-based miner, particularly over how to fund Oyu Tolgoi’s expansion. Rio has also drawn criticism from some of Turquoise Hill’s minority shareholders about the control it exerts over the company.
The global miner, which has mined copper from Oyu Tolgoi’s open pit for a decade, and the Mongolian government ended earlier this year a long-running dispute over the $7 billion expansion of the mine.
Rio Tinto chief executive Jakob Stausholm has said the proposed takeover would simplify governance, improve efficiency and create greater certainty of funding for the long-term success of the Oyu Tolgoi project.

First female minister of mining in Chile dies at 57
Karen Poniachik, well known Chilean journalist who became the country’s first female minister of mining and sat in the board of Lundin Mining (TSX: LUN) among other companies, has died at the age of 57.
She led Chile’s mining ministry from March 2006 to January 2008, as part of the first government of Michelle Bachelet — so far the only woman to have been elected the country’s President.
Poniachik steered the negotiations that helped Chile to become a member of the Organization for Economic Co-operation and Development (OECD), being the first South American nation accepted in the group.
“Karen brought a wealth of experience, wisdom and insight to our board gained through her distinguished career and many contributions to mining in Chile,” Lundin Mining chairman Adam Lundin said in a statement. “She will be greatly missed by many.”
Since 2011 and until her death on Oct. 12, Poniachik was the director of the Columbia Global Center in Santiago, Chile’s capital, where she promoted research on issues such as climate change, gender equality, health and innovation.
In addition, the senior executive had been appointed by President Gabriel Boric as one of the new representatives of Chile in the APEC Business Advisory Council (ABAC), a body that provides APEC leaders with perspectives, private sector recommendations and action plans.
Although the cause of death has not been officially released, Poniachik was diagnosed with breast cancer at age 35.

Resolute Mining inks deal for up to 80% of African Gold project in Mali
Australia’s Resolute Mining (ASX, LON: RSG) has struck an earn-in agreement with African Gold (ASX: A1G) that would allow it to earn up to an 80% interest in the junior’s Syama shear zone project, in the south of Mali.
Resolute, which was a gold miner in the home country for about 30 years before gravitating towards West Africa, could become the project’s majority owner by spending $500,000 on exploration over the next two years. It would also need to start a feasibility study within five years and complete it within eight.
If Resolute decides to mine the asset, African Gold can elect to contribute to the development of the project to maintain its equity or dilute to a 1.5% net smelter royalty.
The Western Australia-based miner already has a mayor operation in the area, comprising the Syama underground mine, the Tabakoroni open pit and several satellite oxide pits.
Resolute Mining chief executive Terry Holohan has been trying for years to prove Barrick’s CEO Mark Bristow wrong. As the leader of Randgold Resources, which merged with the Canadian gold miner in 2018, Bristow decided against developing the gold resource at Syama into a mining operation.
He said at the time the project, located 300km southeast of the capital Bamako and about 30km from the border with Côte d’Ivoire, was technically too difficult to mine.
“We thought we could crack the metallurgy,” Holohan, who took over as CEO in May, told The African Report. “We’ve now ticked the box.”
The executive added he was looking forward to updating Bristow on the project’s progress. “That conversation will happen.”
African Gold managing director Phillip Gallagher said Resolute was the “natural partner” to develop the Syama shear zone project as it is contiguous to Resolute’s Syama gold mine.
“The agreement allows African Gold to maintain a meaningful interest in the Syama Project with the option to participate in the future development of the project, if it chooses to do so,” Gallagher said in the statement.
African Gold will now focus its efforts on its flagship Didievi gold project in Cote d’Ivoire and its Senegal-Mali shear zone projects in northern Mali, Africa’s third-largest gold producer.
The country is home to industrial mines operated by companies including Barrick Gold, B2GOLD, AngloGold Ashanti and Hummingbird Resources.

Wits Mining Institute seminar sees launch of two new SAMERDI research centres
As the University of the Witwatersrand (Wits) celebrates 100 years since its doors opened in 1922, the Wits Mining Institute (WMI) recently hosted its inaugural annual Seminar, which highlighted the value of innovative research in developing mining technology for the future of the industry.
Speaking at a WMI Seminar held at the Wits Club during the last week of September, WMI director Professor Glen Nwaila noted that although the mining industry in South Africa had some turbulent times during its 100 years, the WMI continued to innovate while holding at its core the sustainable provision of minerals to support the future wellbeing of the industry.
“The WMI looks to specifically create the environment to foster the characteristics for research, innovation and development, alongside excellent relationships with our stakeholders”, he said.
Under the theme of ‘Turning research curiosity into 21st Century minerals industry performance, relationships and technology’, Nwaila said it could not have developed advanced technologies for the 21st Century model of mining – which included SmartMine Internet of Things (IoT), wearable technologies and sensors, safe blast imitation and optimisation and point-cloud surveys, without ongoing, multidisciplinary partnerships.
He said that through this research, innovation and development, and ongoing public-private partnerships, Wits was not only able to progress cross- and trans-disciplinary research and solutions for the mining industry but was also able to address new and emerging challenges.
This included stumbling blocks under the umbrella of environmental, social, and governance (ESG), the circular economy, mine waste, sustainable process engineering, orebody modelling and geotechnical engineering. Another challenge faced by the industry as mines continue to develop, is the question of capacity development.
“The WMI cannot stagnate, as the mining industry continues to be in flux. The research will continue to develop alongside industry, which is developing at a rapid pace,” Nwaila said. “Here at the WMI, we have a curiosity, a technical capability and determination to thrive. Understanding market realities and the management of high-risk and exploratory data-driven projects has also put us at the forefront,” he pointed out.
Industry perspective
Delivering his keynote speech on the first day of the event, diversified miner Sibanye-Stillwater CEO Neal Froneman highlighted that the Sibanye-Stillwater DigiMine laboratory at Wits was an example of one of Sibanye’s strategies to create a better mining world. “Fundamental and applied research within the DigiMine laboratory provides us with strategic intelligence on relevant digital advances to institutionalise innovation.”
Sibanye-Stillwater, which is sharpening its focus on the battery metals space, is further pursuing its 3D strategy to address forces of change within the industry. Dubbed ‘grey elephants’ – a highly probable, high impact, yet neglected catalyst – Froneman pointed out that the company was working towards finding innovative solutions to counter these challenges.
“Our 3D strategy is designed to harness opportunities, manage a complex environment, and facilitate continued growth. We intentionally find new ways to do things better,” he said.
South African Mining Extraction Research, Development & Innovation (SAMERDI)
The WMI Seminar also served as the launch platform of two new research centres established through the SAMERDI strategy.
Hosted by the WMI, the two SAMERDI Research Centres (SRCs) will focus their fundamental research on the themes of Real-Time Information Management Systems (RTIMS) and Successful Application of Technology Centred Around People (SATCAP), respectively. These are two of the thematic areas pursued by the Mandela Mining Precinct (MMP) in Johannesburg, which is administered by the Council for Scientific and Industrial Research (CSIR). The initiative is also funded by the Minerals Council of South Africa (MinCoSA) and the Department of Science and Industry (DSI).
Skills development
Referring to the ‘grey elephants’ raised by Froneman, Prof Gill Drennan, Head of the School of Geosciences at Wits, believed the answer was in skills development.
“Wits is aligning its teachings to develop with the changing world, allowing for multiple skillsets,” Drennan said.
“Therefore, we are reviewing, revitalising and refreshing our curricula to allow for ongoing continuous assessment to increase learning during classroom time and enhance student motivation, combining theory and training embedded in a real-life work environment in interconnected educational ecosystems and encouraging self-directed training and nano-degrees – a certified online education programme that helps students develop specialised skills for lifelong learning,” she said.
