Canada, US must spur critical mineral mining, refining at home to secure clean energy shift, American envoy says

The U.S. ambassador to Canada David Cohen says the shift to clean energy from fossil fuels by Canadian and American governments will succeed or fail depending on whether they can obtain a sufficient supply of critical minerals to make electric vehicle batteries.


Both countries need to build up their mining and refining, and battery making capacity quickly.

“We need to help each other to make this possible – to drive demand for electric vehicles, to help fund critical mineral mines, and to move manufacturing, refining, and mining back to North America, in a responsible way. The United States and Canada are investing billions to make all that happen,” Mr. Cohen told the Canadian Club of Ottawa in a speech Tuesday.

As it stands, he said, China has an unusually large presence in the critical minerals business.

“We’re too reliant on too few, geopolitically unreliable countries,” the envoy said. I don’t need to remind you of what happens when the supply chain breaks down. We lived through that during the pandemic and nobody wants to live through that again.”

He framed the the enormity of the challenge.

“I suspect everyone in this room knows we have a problem. Simply put, we don’t have enough of these minerals today to meet the world’s – and our own – growing demand,” Mr. Cohen said. “Our current supply chain for these minerals – from extraction to production to recycling – is simply not diverse enough for the future that’s coming.”

Demand for critical minerals to make electric vehicle batteries will skyrocket in the years ahead.

He noted the International Energy Agency forecast that demand for most minerals essential to the clean energy transition will increase four to six times over the next decade and a half. “For some minerals, the increase will be exponential. By 2040, graphite demand, for example, will increase by 25 times, and the demand for lithium by 42 times,” Mr. Cohen said.

“As it stands today, China plays an outsized role in the critical minerals industry at every step along the supply chain. This is particularly true when it comes to mining and refining,” the U.S. envoy said.

According to a 2022 Brookings Institution report, China refines 68% of all nickel globally, 40% of copper, 59% lithium, and 73% of cobalt. China also accounts for most global production of mineral-rich components for battery cells.

“Most significantly, China holds 78% of the world’s cell manufacturing capacity for electric vehicle batteries, which are essential for a transition to electric batteries as we try and wean ourselves off of fossil fuels,” Mr. Cohen said.

“Given the current state of play, the status quo will not provide the energy security that Canada, the United States or our democratic friends and allies need for our cleaner energy future.”

He said the U.S and Canada and allies have “woke up to the problem” and legislation such as the 2022 Inflation Reduction Act. The measure offered billions of dollars in incentives to battery-makers and credits for electric vehicles that the legislation says “are extracted or processed in any country with which the United States has a free-trade agreement.”

Now, he said, the U.S. and Canada are trying resolve the problem and “investing billions” to make it happen.

Mr. Cohen said the Inflation Reduction Act and other measures such as the 2021 Bipartisan Infrastructure Law are strengthening regional supply chains, “which are the lifeblood of our economies.”

He said Canadian companies are also benefiting from these funding and investment opportunities, citing the example of Graphite One was awarded $37.5-million from the U.S. Department of Defense under the Defense Production Act to support the development of its graphite mine in Alaska.

As well, he said, at least three Canadian companies stand to benefit from an Oct. 13 announcement by U.S. President Joe Biden to award seven regional clean hydrogen hubs have been selected to receive $7-billion in Bipartisan Infrastructure Law funding to accelerate the move to low-cost, clean hydrogen. Mr. Cohen noted that Enbridge is participating in the Mid-Atlantic Hub, TC Energy in the Heartland Hub, and AltaGas in the Pacific Northwest Hub.

Mr. Cohen celebrated the Canada-United States relationship, saying both countries were at the forefront of efforts to support Ukraine, under invasion Russia, as well as Israel, which was attacked by Hamas in October.

“We’re leading a coalition of the world’s democracies to support Ukraine – and now to support Israel as well,” the envoy said.

He said the two countries are not only bound together by important treaties, such as the United States-Mexico-Canada Agreement, but also by economic relations.

“We’re tied together by trade: a truly incredible C$3.25-billion-plus in goods and services cross our shared border each day, generating or supporting millions of jobs in both of our countries,” he said.

“This makes Canada the number one trading partner for the United States – and it makes the United States the number one trading partner for Canada. In addition, more than 30 U.S. states count Canada as their number one export

BHP to inject $4.9 billion into Jansen to double potash output

BHP (ASX: BHP) said on Tuesday it would invest $4.9 billion in stage two of its giant Jansen potash project in Canada, as it aims to double capacity by the end of the decade.


The investment adds to the $5.7 billion the world’s largest miner is pouring into stage one of the potash project in Saskatchewan, and an investment of $4.5 billion the company sunk into Jansen before its first phase was even approved.


BHP considers potash, used in crops fertilizers, as one of its pillars of future growth. It expects potash demand to increase by 15 million tonnes to roughly 105 million tonnes by 2040, or 1.5% to 3% a year, along with the global population and pressure to improve farming yields given limited land supply.

With the additional investment announced on Tuesday, BHP expects Jansen to become one of the world’s largest potash mines, doubling production capacity to approximately 8.5 million tonnes per year (Mtpa) in late fiscal 2029.

“This is an important milestone that underscores our confidence in potash and marks the next phase of the company’s growth in Canada,” chief executive officer, Mike Henry, said in the statement

The first stage of the project is 32% complete and progressing as per schedule, BHP said. The second stage is expected to take six years and produce about 4.36 mtpa at a capital intensity of about $1,050/tonne, which is in line with BHP’s strategy to invest in large deposits that have high barriers to entry and offer strong margins.

The company’s move shouldn’t come “as too much of a surprise”, BMO analyst Alexander Pearce wrote in a note to investors.

“A final investment decision decision in FY2024 [has been] well flagged and there has been increased focus on the project in recent presentations (…) However, nearer term, the higher combined cash costs ($105-120/t, +5-20%), and a slightly lower run rate for Stage 1 is likely a slight negative,” Pearce said.

BHP had tried to tap into the fertilizer market for some time. In 2010, it unsuccessfully bid $38.6 billion for Potash Corp. of Saskatchewan, which in 2018 merged with Agrium Inc. to form Nutrien (TSE, NYSE: NTR).

Jansen had the potential to produce 16-17 million tonnes of potash a year under a four-phased development. This would account for about 25% of current global demand.

BHP had originally planned to begin production at Jansen in 2027. Market conditions, including Russia’s invasion of Ukraine and sanctions on Belarusian potash, prompted it to bring forward stage 1 first production into 2026.

Australia’s Lucapa Diamond (ASX: LOM) has recovered a 208 carat diamond at its prolific Lulo mine in Angola, the third-largest ever found at the operation.


The company said the high-quality, type IIa diamond was unearthed at the lizeria, or terrace area, of its Mining Block 31 portion of Lulo, known for delivering high-value stones.

The diamond is also the second 100-carat-plus stone Lucapa retrieved in October, following the recovery of a 123-carat, type IIa rough at the start of the month.

The mine, which hosts the world’s highest dollar-per-carat alluvial diamonds, began commercial production in January 2015. Only a year later, it delivered the largest ever diamond recovered in Angola — a 404-carat white stone later named the “4th February Stone”.

The operation has delivered 39 diamonds weighing more than 100 carats each to date.

Lucapa has a 40% stake in the Lulo mine. The rest is held by Angola’s national diamond company (Endiama) and Rosas & Petalas, a private entity.

Angola is the world’s fifth diamond producer by value and sixth by volume. Its industry, which began a century ago under Portuguese colonial rule, is successfully being liberalized.

Letšeng Mine Yields 117.47-Carat Rough for Gem Diamonds

This exceptional find marks the fourth time in the current year that Gem Diamonds has unearthed rough diamonds exceeding 100 carats, reinforcing the mine's reputation for producing high-quality gemstones
Letšeng Mine Yields 117.47-Carat Rough for Gem Diamonds


Gem Diamonds announced the recovery of a 117.47-carat rough diamond from its Letšeng mine in Lesotho. This marks the fourth time this year that the company has unearthed a rough diamond exceeding 100 carats.

The discovery of this gem-quality, type IIa diamond occurred on October 29, with Gem Diamonds revealing the news on Tuesday. This find comes in the wake of a 101.96-carat high-quality rough diamond discovered on September 28, a 163.91-carat yellow diamond on June 22, and a 122-carat stone found on March 5.

Letšeng Mine has long been recognized for producing high-quality rough diamonds, frequently exceeding 100 carats. However, recent years have seen a decline in such discoveries. Nevertheless, this latest recovery has matched the previous year's total, during which the company also retrieved four diamonds in this category. This compares to six such diamonds in 2021 and 16 in 2020.

The decreasing number of special-size stones has impacted the company's revenue, resulting in a 28% year-on-year sales decline to $71.8 million in the first half of 2023. Gem Diamonds incurred a loss of $1 million, in contrast to a profit of $3.8 million during the same period in 2022.

Canada Unearths its Largest-Ever Yellow Diamond in Tiffany Crafts

Sourced in Canada, the diamond represents Tiffany’s relentless pursuit of the most exceptional gemstones that the world has to offer.

As the largest rough Fancy Vivid Yellow diamond ever discovered in Canada, weighing over 71 carats, the remarkable rough gem was sustainably sourced from the Ekati Mine in the Northwest Territories of the region. It is considered a miracle of nature and is extremely rare due to its highly saturated vivid yellow hue and showcased a near-perfect octahedral shape.

Tiffany & Co. artisans cut each in the highly coveted classic emerald shape. Victoria Wirth Reynolds, Chief Gemmologist, Tiffany & Co., said, “Our artisans handcrafted this rough stone into two gems of unparalleled vivid yellow colour and brilliance—transforming nature’s miracles through the exceptional skill of Tiffany craftsmanship.”


Gold mining spreads mercury to tropical birds, study says

Tropical birds, from kingfishers to wrens to warblers, are showing signs of mercury contamination as artisanal and small-scale gold mining operations reach deeper into jungles, new research finds.


Birds living within 7 km (4 miles) of such gold mining activity were found to have mercury concentrations over four times higher than those living at other sites across the tropics of Central and South America, according to the study published Tuesday in the journal Ecotoxicology.


“It’s a wake-up call for bird conservation internationally across the tropics,” said lead author Chris Sayers, a conservation biologist at the University of California Los Angeles.

Tropical bird biodiversity has been decliningin recent decades, but scientists are not fully sure why. “Based on the levels here, it’s reasonable to suggest that mercury may be playing a role,” Sayers said.

Over a 17-year period ending in 2023, dozens of scientists collected thousands of feather, blood and tissue samples from 322 bird species across nine countries in Central and South America and the West Indies, creating the world’s largest database to date on mercury concentrations in birds.

The research adds to a growing understanding of how mercury, which is used by gold miners to separate the precious metal from sediment, is impacting wildlife in the tropics.

Artisanal gold mining is often either carried out illegally in protected areas, or done informally outside reserves but without explicit government permission.

Earlier this year, Reuters reported for the first time that scientists were finding mammals, from titi monkeys to ocelots, showing signs of mercury contamination near a Peruvian gold mining hotspot.

Absorbing or ingesting mercury-contaminated water or food has been found to cause neurological illness, immune diseases and reproductive failure in humans and some birds.

Birds are the “canary in the gold mine,” Sayers said, as they are sensitive to mercury pollution and easily accessible, allowing scientists to take the temperature of overall ecosystem health.

The collected samples revealed some of the highest-ever recorded mercury concentrations in songbirds. Birds that ate meat or lived in aquatic habitats were also found to have the highest overall mercury levels.

Hotspots for mercury contamination included Madre de Dios, Peru, and Ayapel, Colombia – centres of artisanal gold mining.

Birds in central Belize also had high mercury concentrations, with scientists speculating it could be due to gaseous mercury emissions from local landfill incineration, or coal combustion in the surrounding region.

How sunflowers see the sun

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers “see” the sun to follow it? New work from plant biologists at the University of California, Davis, published Oct. 31 in PLOS Biology, shows that they use a different, novel mechanism from that previously thought. 

“This was a total surprise for us,” said Stacey Harmer, professor of plant biology at UC Davis and senior author on the paper. 

Most plants show phototropism – the ability to grow toward a light source. Plant scientists had assumed that sunflowers’ heliotropism, the ability to follow the sun, would be based on the same basic mechanism, which is governed by molecule called phototropin and responds to light at the blue end of the spectrum. 

Sunflowers swing their heads by growing a little more on the east side of the stem – pushing the head west – during the day and a little more on the west side at night, so the head swings back toward the east. Harmer’s lab at the UC Davis College of Biological Sciences has previously shown how sunflowers use their internal circadian clock to anticipate the sunrise, and to coordinate the opening of florets with the appearance of pollinating insects in the morning. 

In the new study, graduate student Christopher Brooks, postdoctoral researcher Hagatop Atamian and Harmer looked at which genes were switched on (transcribed) in sunflowers grown indoors in laboratory growth chambers, and in sunflowers growing in sunlight outdoors. 

Indoors, sunflowers grew straight toward the light, activating genes associated with phototropin. But the plants grown outdoors, swinging their heads with the sun, showed a completely different pattern of gene expression. There was no apparent difference in phototropin between one side of the stem and another. 

The researchers have not yet identified the genes involved in heliotropism. 

“We seem to have ruled out the phototropin pathway, but we did not find a clear smoking gun,” Harmer said. 

Blocking blue, ultraviolet, red or far-red light with shade boxes had no effect on the heliotropism response. This shows that there are likely multiple pathways, responding to different wavelengths of light, to achieve the same goal. Upcoming work will look at protein regulation in the plants. 

Sunflowers are quick learners. When plants grown in the lab were moved outdoors, they started tracking the sun on the first day, Harmer said. That behavior was accompanied by a burst of gene expression on the shaded side of the plant that did not recur on subsequent days. That suggests some kind of “rewiring” is going on, she said. 

Apart from revealing previously unknown pathways for light-sensing and growth in plants, the discovery has broad relevance, Harmer said. 

“Things that you define in a controlled environment like a growth chamber may not work out in the real world,” she said. 

Atamian is now an assistant professor at Chapman University. 

 

Studies illustrate moderate awareness—and room for growth—with new 988 lifeline


Public survey and social media analysis provide insight into knowledge and use of the lifeline


Peer-Reviewed Publication

NEW YORK UNIVERSITY




Two studies led by researchers at NYU’s School of Global Public Health and Silver School of Social Work and published in JAMA Network Open show emerging awareness of the new 988 Suicide and Crisis Lifeline among both policymakers and the general public—but also point to potential areas of improvement for the vital nationwide service.

 

In July 2022, “988” became the new number for the National Suicide and Crisis Lifeline, which provides a phone, text, and chat resource for people who are experiencing suicidal thoughts, hopelessness, substance use crises, and other psychological distress. Similar to dialing 911 in emergencies, the use of a three-digit dialing code for mental health crises is designed to be accessible and easy to remember.

 

However, public awareness of 988 is off to a slow start, according to a survey conducted this spring. To better understand whether people know about and use 988 depending on their mental wellbeing, and to get a sense of how much policymakers are communicating about 988, the researchers undertook two studies about the 988 Lifeline during its nascency.

 

Knowledge and use of 988 varies based on mental health status

In one study, published Oct. 31, the researchers surveyed 5,058 U.S. adults to see if people with varying degrees of psychological distress had different levels of awareness and use of 988. 

 

In the nationally representative, web-based survey of U.S. adults conducted in June 2023, they asked participants about their mental health—including whether they feel nervous, hopeless, depressed, or worthless, and whether these feelings hurt their ability to function. They also asked participants whether they had heard of 988, had used 988 themselves, and their likelihood of using 988 in the future if they or a loved one were experiencing a crisis or suicidality.

 

The researchers found that people with serious and moderate psychological distress were significantly more likely to have heard of 988 (47.4% and 45%) than those without distress (40.4%). In addition, 6% of people with serious psychological distress reported using the 988 Lifeline, making them more than 30 times as likely to use the lifeline compared to those with no distress (0.2%) and six times more likely to use 988 than those with moderate distress (1%).

 

Notably, when asked if they would use 988 in the future if needed, only 30% of those reporting serious psychological distress who had used 988 were very likely to use it again.

 

“Our findings signal a need for research about satisfaction with the 988 Lifeline among people with serious psychological distress and the extent to which 988—and the resources it connects users to—sufficiently meets their needs,” said Jonathan Purtle, associate professor in the NYU School of Global Public Health, who led the research.

 

“Launching the 988 hotline has been a critical step for addressing America’s expanding need for mental health services, but we have to get to the bottom of why so many users who were in serious distress wouldn’t use it again—whether that means better training is needed, more resources or other solutions,” said Michael A. Lindsey, Dean and Paulette Goddard Professor of Social Work at the NYU Silver School of Social Work.

 

Policymaker social media posts about 988

In the second study, published on Oct. 26, the researchers examined how elected state policymakers communicated about 988 on social media before and after its launch in July 2022. The researchers analyzed Facebook and Twitter (now known as X) posts mentioning 988 from the accounts of state legislators and Washington, DC council members throughout 2022—about six months before and after the launch of 988.

 

A total of 1,000 state legislators published 2,041 social media posts about 988 during the period studied. Posts were the most prevalent in California (132.7 per 10,000 posts) and least prevalent in West Virginia (1.4 per 10,000 posts). Democratic legislators were 31% more likely to post about 988 than were Republican legislators.

 

In addition, more than half of the posts (54%) occurred in July 2022—around the launch of 988. Another 22% took place in September 2022, which was Suicide Prevention Awareness Month, and few posts were published during other months.

 

“We found that many state legislators actively communicated about 988 when it was launched in July 2022, but that communication was not sustained over time,” said Purtle. “Robust public awareness of the 988 Lifeline and willingness to use in crisis situations is critical to realizing its public health impact.”

 

In addition to Purtle and Lindsey, NYU researchers Anna-Michelle Marie McSorley, and Abigail Lin Adera co-authored the study on public use and awareness of 988. Purtle, Michael Soltero and Anna-Michelle Marie McSorley of NYU School of Global Public Health, Margaret E. Crane of Weill Cornell, and Molly Knapp and Christopher Drapeau of Vibrant Emotional Health, which supports coordination of the 988 Lifeline, were additional co-authors of the study of state legislator social media posts. The research was supported in part by the National Institute on Mental Health (R01MH131649).

Philadelphia, October 31, 2023 – Heart attacks, or acute myocardial infarction (MI), are one of the leading causes of death worldwide. The newly released Canadian Cardiovascular Society Classification of Acute Myocardial Infarction (CCS-AMI) appearing in the Canadian Journal of Cardiology, published by Elsevier, presents a four-stage classification of heart attack based on heart muscle damage. This work by a group of noted experts has the potential to stratify risk more accurately in heart attack patients and lays the groundwork for development of new, injury-stage-specific and tissue pathology-based therapies.

Lead author Andreas Kumar, MD, MSc, Northern Ontario School of Medicine University, and Department of Cardiovascular Sciences, Health Sciences North, Sudbury, ON, Canada, explains: “MI remains a leading cause of morbidity and mortality. Existing tools classify MIs using a patient’s clinical presentation and/or the cause of the heart attack, as well as ECG findings. Although these tools are very helpful to guide treatment, they do not consider details of the underlying tissue damage caused by the heart attack. This expert consensus, based on decades of data, is the first classification system of its kind ever released in Canada and internationally. It offers a more differentiated definition of heart attacks and improves our understanding of acute atherothrombotic MI. On a tissue level, not all heart attacks are the same; the new CCS-AMI classification paves the way for development of more refined therapies for MI, which could ultimately result in better patient clinical care and improved survival rates.”

The CCS-AMI classification describes damage to the heart muscle following an MI in four sequential and progressively severe stages. Each stage reflects progression of tissue pathology of myocardial ischemia and reperfusion injury from the previous stage. It is based on a strong body of evidence about the effect an MI has on the heart muscle.

As damage to the heart increases through each progressive CCS-AMI stage, patients have dramatically increased risk of complications such as arrhythmia, heart failure, and death. Appropriate therapy can potentially stop injury from progressing and halt the damage at an earlier stage.

  • Stage 1: Aborted MI (no/minimal myocardial necrosis). No or minimal damage to the heart muscle. In the best case the entire area of myocardium at risk may be salvaged.
  • Stage 2: MI with significant cardiomyocyte necrosis, but without microvascular injury. Damage to the heart muscle and no injury to small blood vessels in the heart. Revascularization therapy will result in restoration of normal coronary flow. 
  • Stage 3: MI with cardiomyocyte necrosis and microvascular dysfunction leading to microvascular obstruction (i.e., “no-reflow”). Damage to the heart muscle and blockage of small blood vessels in the heart. The major adverse cardiac event rate is increased 2- to 4-fold at long-term follow-up.
  • Stage 4: MI with cardiomyocyte and microvascular necrosis leading to reperfusion hemorrhage. Damage to the heart muscle, blockage and rupture of small blood vessels resulting in bleeding into the heart muscle. This is a more severe form of microvascular injury, and the most severe form of ischemia-reperfusion injury. It is associated with a further increase in adverse cardiac event rate of 2- to 6-fold at long-term follow-up.

Dr. Kumar concludes: The new classification will help differentiate heart attacks according to the stage of tissue damage and allow healthcare providers to estimate a patient’s risk more precisely for arrhythmia, heart failure, and death. The CCS-AMI is ultimately expected to lead to better care, better recovery, and better survival rates for heart attack patients.”

In an accompanying editorial, Prakriti Gaba, MD, Brigham and Women’s Hospital, Harvard Medical School, and Deepak L. Bhatt, MD, MPH, Mount Sinai Heart, Icahn School of Medicine at Mount Sinai, comment: “Kumar et al. present a novel and intriguing four-tiered classification scheme of patients with acute MI. This allows unique utilization of prognostic pathologic features to help distinguish between high and low risk acute MI patients. Greater access to cardiovascular magnetic resonance would be needed to implement this new clinical approach broadly, however, for research on emerging diagnostic and therapeutic strategies, it could be implemented immediately.”
