Illegal gold mining in the Amazon has intensified, with one expert calling it a ‘transnational crime’

The rising value of gold worldwide has amplified illegal mining in the Amazon, where liquid mercury is being dumped in the Amazon River and causing scientists to warn that Indigenous communities and the environment could pay a far greater price.

Three weeks ago, Colombia, Brazil and the United States partnered up to destroy 19 illegal gold mining dredges in the Amazon Rainforest. According to Reuters, the dredges were producing about $1.9 million Cdn in gold.

How to detox coal country – by Kate Morgan (Vox.com – December 11, 2023)

https://www.vox.com/

To clean up poisoned streams, Appalachian researchers are turning acid mine drainage into something unexpected.

The most striking thing about the water tumbling out of the ground behind a small cluster of houses in southeastern Ohio isn’t the smell — a sharp, unmistakable sulfur. It’s also not the color, a vibrant red-orange. The weirdest thing about the Truetown Discharge is the silence.

Just before dark on a warm autumn night, there should be a cacophony of crickets and cicadas in the tall grass along the water. Frogs should be singing and splashing into the shallows. Bats should be circling, owls calling, small mammals and salamanders skittering in the leaves.

Navajo Nation faces possible new threats after decades of uranium mining – by Kate Holland and Tenzin Shakya (ABC News – December 7, 2023)

https://abcnews.go.com/

A Canadian company is working to move forward with uranium extraction.

Just miles from the site of the 1979 Church Rock Mill spill, the largest nuclear disaster in American history, uranium extraction operations could resume near the Navajo Nation. Now, Navajo leaders say the health and prosperity of their community could be in even further jeopardy.

A Canadian company is working to move forward with uranium extraction, an industry that has a lengthy history around the Navajo Nation. “The pursuit of happiness for us is to be able to live in our communities without fear from the impact of radiation and uranium,” said Teracita Keyanna, who grew up near an abandoned uranium mine in New Mexico. “It’s been really scary, just being a mom in this area.”

Researchers bring the ‘Sudbury method’ to Peru, to help clean up mine waste (CBC News Sudbury – November 18, 2023)

https://www.cbc.ca/news/canada/sudbury/

Scientists say work in Sudbury to rehabilitate the landscape damaged by mining is recognized worldwide

Researchers from northern Ontario are in Peru where they are sharing their knowledge of what has become known as the “Sudbury method.” The Sudbury method refers to the community’s work over decades to rehabilitate a landscape damaged by mining and smelting.

“Sudbury has become recognized almost globally now for taking one of the most damaged landscapes on planet Earth and through a lot of work by citizens, community members, industry and government, turning it into actually a really, really nice place to live,” said Graeme Spiers, an emeritus professor in environmental and earth sciences at Laurentian University.

U.S., Canada and Ktunaxa Nation to discuss coal-mining pollution in Kootenai River watershed (Montana Free Press – November 9, 2023)

Home

At the first-of-its-kind meeting, representatives of U.S., Canadian and tribal governments will discuss water quality impacts stemming from an expansive coal-mining operation in British Columbia.

After years of delays and false starts, eight governments impacted by an expansive Canadian coal-mining operation are set to meet today on Indigenous territory in Cranbrook, British Columbia, to discuss the future of the governments’ shared waterways.

The meeting will include representatives from the federal governments of the United States and Canada and the Ktunaxa Nation Council, which advocates for the interests of six bands of Indigenous people spread across present-day British Columbia, Montana and Idaho. The council, which includes representation from the Confederated Salish and Kootenai Tribes, has for years asked for greater oversight of Teck Resources’ British Columbia-based coal-mining operation.

Mercury is still an environmental threat – by Tristan Ahtone (Grist.org – November 9, 2023)

https://grist.org/

The heavy metal is poisoning Indigenous peoples’ environment and health, but no one can agree on how or when to get rid of it.

The negotiations produced no particularly big wins. There is still no agreement on a common, global method to measure and identify mercury-contaminated waste from industrial sources, like chemical manufacturers or oil and gas operators.

Mercury can still also be purchased online and traded internationally, and states could not agree on when to pull it from tooth fillings. But there were some successes: Nations have agreed to ban the use of mercury as a preservative in cosmetics by 2025 as well as to increase support for Indigenous peoples in future negotiations.

OPINION: Canada is endangering our traditional way of life — and Sen. Murkowski made sure the president knows – by Richard Chalyee Éesh Peterson (Achorage Daily News – November 4, 2023)

https://www.adn.com

Richard Chalyee Éesh Peterson is the president of the Central Council of the Tlingit and Haida Indian Tribes of Alaska, the largest sovereign tribe in Alaska, representing more than 37,000 Tlingit and Haida citizens worldwide.

The transboundary T’aakū (Taku), Shtax’héen (Stikine) and Joonáx (Unuk) rivers have provided for Indigenous peoples for thousands of years. These rivers are economic powerhouses for Southeast Alaska’s coastal communities.

Today, however, the headwaters of these sacred rivers are the site of a modern-day gold rush with investors aiming to develop poorly regulated gold mines and failure-prone toxic mine waste dams in British Columbia (B.C.).

Cast a ballot, learn about Giant Mine: public info session on arsenic trioxide takes place on election night – by Mah Noor Mubarik (CBC News Canada North – November 1, 2023)

https://www.cbc.ca/news/canada/north/

Session is meant to help people learn about long-term plans for toxic arsenic trioxide

An independent board meant to review the Giant Mine clean-up is holding an information session so people can learn more about long-term plans for the highly toxic arsenic trioxide buried underneath the mine site. The session will be held on the same evening as the territorial election.

The Giant Mine Oversight Board’s chair, David Livingstone, said the date for the meeting was set before wildfires led to the postponement of the election. He said it took four months to set up and would be impossible to reschedule easily.

Cleaning up Australia’s 80,000 disused mines is a huge job – but the payoffs can outweigh the costs – by Mohan Yellishetty and Peter Marcus Bach (The Conversation – October 22, 2023)

https://theconversation.com/

Newly announced closures of Glencore’s copper and zinc mines in Mt Isa will add to a huge number of former mines in Australia. A 2020 study by Monash University’s Resources Trinity Group found more than 80,000 inactive mine sites across the country.

Globally, a 2023 study estimates the mining footprint at around 66,000 square kilometres. Abandoned mines account for much of this area. It’s estimated the US has about 500,000 abandoned mines and Canada at least 10,000. The UK and China have at least 1,500 and 12,000 old coalmines, respectively.

How to turn mine tailings into healthy soil – by Staff (Mining.com – October 10, 2023)

https://www.mining.com/

University of Queensland researchers have developed an innovative method to turn mine tailings into healthy soil. “We have basically taken engineering solutions into the context of natural soil formation from rocks because tailings have some useful minerals common to natural rocks,” Longbin Huang, co-author of the paper that presents the solution, said in a media statement.

In Huang’s view, his team’s proposal could save billions of dollars around the world by minimizing the costs and risks of tailings storage.

Metal-mining pollution impacts 23 million people worldwide – by Victoria Gill (British Broadcasting Corporation – September 21, 2023)

https://www.bbc.com/

At least 23 million people around the world live on flood-plains contaminated by potentially harmful concentrations of toxic waste from metal-mining activity, according to a study. UK scientists mapped the world’s 22,609 active and 159,735 abandoned metal mines and calculated the extent of pollution from them.

Chemicals can leach from mining operations into soil and waterways. The researchers say future mines have to be planned “very carefully”. This is particularly critical as the demand surges for metals that will support battery technology and electrification, including lithium and copper, says Prof Mark Macklin from the University of Lincoln, who led the research.

COMMENTARY: It’s time for U.S. government to hold Canada accountable for transboundary river impacts in Alaska – by Brenda Schwartz-Yeager (Alaska Beacon – August 16, 2023)

Home

Two years ago this fall, I testified at a Wrangell Borough Assembly meeting in support of yet another resolution calling on the U.S. federal government to be firm with British Columbia and Canada in protecting the Stikine River, as well as the Taku and Unuk rivers.

These transboundary rivers, the lifeblood of Southeast Alaska, are threatened by the more than 30 B.C. gold mines in some phase of development just over the border. Over a dozen of them are located within the Stikine-Iskut watershed.
