Chinese Mining Operations in Tajikistan Spark Environmental Backlash



LONG READ

By RFE/RL staff - Jul 22, 2024,

Chinese mining companies in Tajikistan are accused of causing severe environmental pollution and health problems in nearby villages.

The Tajik government, heavily reliant on Chinese investment, often overlooks these issues, allowing the companies to operate with impunity.

Local communities feel their concerns are being ignored and fear for their health and the future of their environment.



For the some 150 people in the tiny Tajik village of Khumgaron, the pollution and waste from the Chinese gold-mining operation nearby is not what they bargained for.

"How will we live if the air and water are polluted?" asked one villager. "What meaning does life have when a person loses their health?"

Fed up with the severe pollution in their village caused by the Zarafshon mining company, a group of angry women traveled to the nearby city of Panjakent last year to file an official complaint on behalf of the village.

But instead of the local officials promising to look into the issue, the women say they were taken to the police station and harshly warned to stop criticizing the sprawling Chinese mining project near their village.

The women, who spoke to RFE/RL on condition of anonymity, say the intimidation has been effective and many villagers are still afraid to voice their grievances about the nearby gold mine.

Ever since the Chinese-run gold mine started operating in western Tajikistan in 2007, villagers say government officials have turned a blind eye to growing air, water, and land pollution in the area -- on land they say the mining company is using without their permission.

This situation near Tajikistan's remote northwestern border with Uzbekistan provides an up-close look at how Dushanbe's growing economic reliance on Chinese investment is playing out on the ground, where Chinese firms are tapping into the country's vast mineral wealth while receiving impunity and preferential treatment from the Tajik government.

A monthslong RFE/RL investigation on four Chinese-run projects in Tajikistan -- including three mining ventures -- highlights this pattern.

Stolen Land?

A resident who asked to remain anonymous showed RFE/RL property deeds in her name for farmland where the Chinese mining operation has built refineries for the gold they extract.

She says this was done without her permission and she has neither been compensated nor received an official response despite raising the issue with Panjakent officials several times. Other villagers make the same claim.

While locals living near these multimillion-dollar investments grapple with environmental degradation and health concerns stemming from the chemicals used in the vast mining and agricultural projects, Tajik officials protect the Chinese companies from public scrutiny because China is Tajikistan's main source of foreign investment.

In the case of the Zarafshon mine, which accounts for 70 percent of the gold mined in Tajikistan, officials at various levels of government who spoke with RFE/RL -- including a high-ranking Environmental Protection Committee official -- praised the company and defended their support for Chinese companies.

They pointed to the firms' economic importance in the investment-starved country and dismissed complaints about environmental pollution.

Tajik President Emomali Rahmon also put his stamp of approval on the Zarafshon plant when he visited it in July 2023.

Please Don't Go

But the high-level official from the Tajik Environmental Protection Committee, the country's main environmental agency, told RFE/RL on condition of anonymity that the state body has been ordered to turn a blind eye to any environmental or health issues stemming from the Zarafshon mine.

"We also have complaints about environmental pollution, but if we put too much pressure on Zarafshon or increase inspections and fines, the Chinese investor may leave Tajikistan," he said. "This would be very harmful for our economy because [the Chinese company] produced some 2.2 billion somoni ($201 million) worth of [gold] in six months of 2023."

He added that Tajikistan's gross domestic product (GDP) in that period was 54 billion somonis ($4.9 billion).

"So imagine the harm that the firm's failure would cause the country's economy," he said.

The official said the taxes levied on the gold mine make up a large part of the budget of Sughd Province, where the mine is located, and that officials don't want to jeopardize this crucial source of revenue by issuing fines for pollution or allowing public criticism to mount.

"If we end the mining operations, the budget will lose millions of dollars," he said.

The official said a similar dynamic exists at other Chinese-run projects that were investigated by RFE/RL, including a gold mine in Pokrud; a lead, zinc, and copper mining site in Zarnisor; and a cotton farming venture in western Tajikistan.

"There is currently no other option but to put up with this situation [of the Chinese companies polluting the environment]," he added.

A New Dependency

The poorest country in Central Asia, Tajikistan's economy has struggled over the years as it has grappled with the fallout from a devastating civil war in the 1990s and has relied on Russia for trade, investment, and loans. With a major shortage of jobs, Tajik migrants have flocked to Russia and the remittances they send home are estimated by the World Bank to be more than 40 percent of Tajikistan's GDP.

But autocratic President Rahmon, who has ruled Tajikistan with an iron fist since 1994, has moved the country closer to Beijing and is an enthusiastic member of its flagship Belt and Road Initiative (BRI).

Since 2010, China has emerged as the country's largest trade partner, foreign investor, and lender, with Beijing owning more than half of Dushanbe's foreign debt.

As Dushanbe has increasingly looked to the East, China has taken pole position in the country's economy, building new roads and investing in sectors such as telecommunications, agriculture, and mining -- where Tajikistan needs financial help to develop the expensive infrastructure required to exploit its mineral wealth.

Chinese construction firms have also built several important government buildings in the heart of Dushanbe, the capital, including the country's new parliament building.

Rahmon said in Dushanbe on July 5 during an official visit by Chinese leader Xi Jinping that China invested more than $4 billion in Tajikistan from 2007 to 2023 and that more than "700 companies with Chinese capital" are operating in the country.

The Tajik president added that the work of Zarafshon is "a clear example of effective investment cooperation between the two countries."

Beijing's oversized economic footprint has translated into political influence, with China becoming an important pilgrimage for Rahmon and members of his powerful family. Beijing has also played a growing security role in the country with joint counterterrorism exercises, police exchanges, and approval to operate a series of outposts inside Tajikistan near its southern border with Afghanistan.

Tajikistan's increased dependency on its eastern neighbor has fueled fears about its growing influence and the concern that the majority of Chinese investment in Tajikistan has come as loans, which Dushanbe might not be able to repay.

Tajiks have already paid a steep price for the country's indebtedness: In 2011, Tajikistan ceded more than 1,000 square kilometers of its territory to China in return for canceling an unspecified debt.

A similar dynamic is at play in Tajikistan's mining sector, where two Chinese-operated mines -- Zarafshon and Pokrud -- account for 84 percent of the country's annual gold output. In the case of Zarafshon, the mine alone paid some $40 million in taxes in 2021 compared to a total national budget of nearly $3.9 billion.

In 2016, the Tajik government banned the publishing of official statistics about gold production in the country, but statements by ministers in 2019 and 2023 claim it has been rising by more than 10 percent annually and China's Zijin company has continued to expand its operations at Zarafshon. The profits made in Tajikistan by the Chinese mining companies are also not made public.

Tajik authorities have also continued to green-light new Chinese investments in the mining industry, often with seemingly little public debate.

In 2019, for instance, the Tajik parliament approved a deal with China's Kashgar Xinyi Dadi Mining Investment Company to develop the Yakjilva silver deposit in the remote eastern district of Murghob after less than 30 minutes of debate.

The Tajik government has defended China's growing position within the mining sector by claiming that Chinese firms have set themselves apart by being the only foreign companies willing to take on such large projects.

"Only the Chinese are willing to invest and develop mines [in the country]," Zarobiddin Faizullozoda, the former head of the Industry and New Technologies Ministry, which oversees the mining industry, said while minister in 2019.

Green Tomatoes

Asadullo Rahmonov, a 62-year-old farmer from Khumgaron, says the quality of the produce he grows has diminished in recent years as the scale of operations at Zarafshon has expanded, including a new 30-hectare area granted by the government in December.

"The tomatoes don't ripen very well anymore, and I've been planting cucumbers for three years. They bloom, their flowers fall off, but they don't grow," he said. "The peaches also only ripen halfway and then fall from the tree. This wasn't the case even a few years ago."

Five other local farmers who spoke to RFE/RL on condition of anonymity for fear of reprisal for criticizing the Chinese mining operation also claimed that the nearby gold refinery is affecting harvests and the environment at large, pointing to a dark-colored dust that is found in streams and on agricultural fields.

The gold mine in Zarafshon has been operational since 1994 and was managed by the British-based Commonwealth and British Mineral firm until Zijin acquired a 70 percent share in 2007. The remaining 30 percent of the mine is owned by the Tajik government. Profits from the gold that is mined are divided based on ownership percentage.

The gold mine currently employs some 2,800 workers, with Zarafshon Deputy Director Bobokhon Bobokhonov telling RFE/RL that 98 percent of workers are Tajik citizens. And job security seems good, as he added that Zijin recently had its rights to the land extended by 20 years.

The mined gold is refined nearby as well as at refineries near Panjakent -- which is some 20 kilometers to the east -- for further purification, and locals primarily blame this process for the adverse effects on the environment.

The dominant method in the world for refining gold involves using cyanide: a highly toxic chemical used to extract gold from the rock that can be fatal to humans.

Flaviano Bianchini, the director of Source International, an NGO focused on environmental pollution, said cyanide should only be used in controlled environments and that even small amounts in the environment can contaminate an entire area.

"If you lose 1 kilogram of cyanide into a water supply, that could easily kill 200 people or completely destroy the environment around it," he told RFE/RL.

The crushed rock from the mine is transported to the refinery where it is treated with cyanide, which dissolves the gold from the rock. While cost-effective, it is considered very damaging to the environment. The use of cyanide in mining operations has forced the displacement of many communities around the world.

Most scientists agree that cyanide decomposes in sunlight and is not dangerous if greatly diluted, but its use can also release harmful metals from the rock. Multiple studies have shown that cyanide can convert into other toxic forms and persist, particularly in cold climates.

Gold mining itself is also a waste-intensive process. Some estimates say that 10-15 grams of gold can be found for every one ton of rock, leaving more than 999 kilograms as waste, which can also take the form of harmful dust.

Stillborn Babies

Villagers from Khumgaron told RFE/RL that they believe cyanide is being used in high levels and has seeped into the ground, polluting the environment, damaging fruit and vegetable harvests, and causing health issues for residents.

In 2022, village residents signed a letter and sent it to the Tajik President's Office complaining of worsening health issues that they associate with the nearby mine.

"[Villagers] are getting sick more often, childlessness in young families due to the number of stillborn babies has increased," the letter read.

Residents also complain that the air in the village is dirty because of the pollution emitted by the Zarafshon gold and lime refineries and say there is a foul odor when the wind blows. Residents from Shing -- a village near the Zarafshon mine in the Panjakent region -- told RFE/RL that the number of people who complain of breathing problems has increased.

The Health Ministry in Panjakent told RFE/RL it does not have cumulative statistics on health issues affecting the people of Khumgaron and said to contact the Health Ministry's main office in Dushanbe. So, too, did the Central Hospital and the Sanitary and Epidemiological Department in Panjakent.

But the Health Ministry did not supply any information to RFE/RL despite a formal inquiry sent in November 2023 and in direct talks with a ministry spokesperson.

Zarafshon mine officials would not agree to an interview with RFE/RL or respond to written requests for comment.

Despite refusing to acknowledge criticism of the mining site in Zarafshon and people's complaints of pollution and its adverse health effects, Tajik officials have issued some token fines to the Chinese company over the years.

The operation was fined in 2019 for dumping waste from a lime production plant attached to the mine in Shing into the Shing River. Tajik authorities said the dumping was responsible for a mass die-off of fish in the river.

Yet the company was only fined the equivalent of about $1,100.

A far more severe fine came four years later when Tajik Prosecutor-General Yusuf Rahmon (an in-law of President Rahmon) announced in April 2023 that the Zarafshon mine operators would be fined the equivalent of $1.7 million for causing some $14.6 million in environmental damage. No details about the damage were given, but the head of Panjakent's Environmental Department told RFE/RL that the fine was issued because part of the onsite refinery was built without applying for regulatory documents.



Broken Promises

The years of complaints from Khumgaron residents led to the mining company beginning a community outreach program in 2021 with promises to build four kilometers of a new road, renovate a school (costing about $90,000), and install plumbing to bring drinking water into the villagers' homes.

The company also agreed to pay a lump sum of $13,700 per month to the villagers -- approximately $90 per resident. It says the money will be paid "until the Tajik government provides land plots to 47 farmers and their families."

But besides the cash payment to the village, Khumgaron residents said the company's other grand promises went unfulfilled.

As part of government requirements for companies to keep a mining license, firms engaged in mining must make some improvements for local residents, such as building a school, a hospital, or a road.

But in a very rare bit of public criticism in 2018, then-Industry and New Technologies Minister Shavkat Bobozoda said at a press conference that none of these obligations had been fulfilled by the Zijin mining company.

"They have already extracted 20 tons of gold, but they could leave tomorrow [and] what else would remain there?!" he exclaimed to a room of reporters.

A 2023 visit by RFE/RL to the village showed that none of the construction projects had begun and the main road remained in disrepair, which residents say is damaged by the heavy trucks carrying rocks that constantly travel back and forth from the mine.

Sanat Rahim, the head of the Tajik industry and mining sector's inspection service, said at a press conference in July 2023 that one of the government's "strategic goals" is "rapid industrialization."

He explained that setting up an industry leads to the establishment of "a refinery, a garbage dump, [etc.], and new businesses are created. Ecology and industrialization do not go hand in hand [but]…. We specialists must as much as possible reduce the [environmental] damage caused by industrialization."

'It Could Kill People'

Some 350 kilometers from Khumgaron and the Zarafshon mining operation sits the Pokrud gold mine, another vast Chinese mining project where locals say pollution is contaminating rivers and nearby land.

Here, the China Nonferrous Gold (CNG) company operates a gold concession with 100 percent ownership, with internal CNG reports from 2021 seen by RFE/RL saying that the company "has a strong relationship with the government of Tajikistan." In the same report, the firm lauds its environmental standards and claims it has a strong relationship with the local communities.

Located in Tajikistan's Romit Gorge, villagers living close to the mine say that the only benefit they've felt from the gold mine is that CNG has built a road to access its deposits that villagers from the remote, mountainous area can also use.

But they say contamination is increasing from the Chinese-owned mine.

Residents of several upstream villages in the area told RFE/RL that the company pours wastewater from its refinery directly into the sprawling Romit River. Several villagers said that they stopped using drinking water taken from the river after several people became ill.

During a 2023 visit to the mouth of the Romit River near the Pokrud mine, RFE/RL reporters saw a pipe coming directly from the refinery and feeding untreated wastewater into the river.

Bianchini, the mining expert from Source International, said such a practice is highly dangerous.

"The water that comes out from the [refining] process is poisoned," he said. "You can't leave water like that. It's not just an issue of polluting the river. It could kill people."

Despite these big concerns, the Chinese company has received minimal scrutiny from Tajik authorities. At the same time, the operation has received high-level political backing.

When the first gold bar from the mine was poured in 2016, Rahmon visited the site and -- in scenes shown on state television -- praised the $256 million Chinese investment while proudly holding two gold ingots.

Tajikistan's Environmental Protection Committee told RFE/RL that it inspected CNG's refinery in the summer of 2023 -- a few weeks after RFE/RL saw the wastewater being dumped into the river -- and said it found a "number of deficiencies, including nonobservance of solid household waste management procedures and an excessive discharge of waste into the atmosphere."

The committee did not comment on the video of the wastewater being discharged into the river.

Big Promises Amid Water Shortages

In Zarnisor -- a town in northern Tajikistan of some 5,000 people about 60 kilometers north of Khujand on the Uzbek border -- there is another high-profile Chinese mining project that is affecting nearby communities.

Established in 2007 as a subsidiary of the Chinese state-owned Tibet Everest Resources, the Tajikistan-China Mining Industry Company (TCMIC) mines lead, zinc, and copper from the area. The mining process for those minerals requires vast quantities of water, which residents say is creating a shortage for them.

Idiboy Fozilov, a pensioner who lives in Zarnisor, said that since the Chinese operation started people have only had access to clean drinking water for one hour a day and people are forced to store drinking water in tanks.

He said that during the Soviet era locals built a water line to bring potable water to the village. But he added that residents have only had access to drinking water for one hour per day -- in the evening -- since the Chinese company arrived.

In addition to shortages, several villagers who spoke to RFE/RL said the company is not upholding its pledge to invest in the local infrastructure.

TCMIC had agreed to repair and refurbish a day-care center, local roads, and provide street lighting for the village. But with the exception of the road that leads to the company's main office, the other roads in the area remain in poor condition and the day-care center is decrepit.

RFE/RL reported very poor roads in Zarnisor, streets not well lit, and the village school dilapidated and in urgent need of repair -- though the road to the central office of the Chinese company and the dorm for its Chinese workers is paved.

As with other Chinese companies involved in Tajikistan's extractive sector, TCMIC plays a particularly large economic role in the country.

In July 2022, its parent company, Tibet Everest Resources, pledged to build an industrial park in Tajikistan that would create 10,000 new jobs. But two years later, there has been no update about the project.

Other numbers issued by Tibet Everest Resources suggest its economic activities also do not add up.

In interviews and public statements over the years, TCMIC executives have claimed the company employs more than 4,000 people in Tajikistan -- but other times have said their workforce totaled about 3,000.

Similar inconsistencies have occurred over the amount of taxes and fees the firm contributes to the state budget.

In 2022, the independent Tajik news agency Asia-Plus quoted TCMIC head Li Yaohui as saying the company had paid 33 billion somonis (some $3.1 billion) in taxes and fees since it began operating in the country in 2009.

But in public comments made in 2021, Li said the company had paid a much smaller amount -- 4.2 billion somonis (about $383 million) -- to the government since its founding.

In comments to RFE/RL, TCMIC defended its record of working with local communities and building infrastructure, claiming it had made school repairs in Zarnisor while also constructing a town hall and repairing a hospital in Guliston, a nearby city of some 50,000 people. The company also funded the reconstruction of 38 kilometers of a remote road linking the towns of Buston and Zarnisor that cost some 100 million somonis ($9.1 million).

An official with the Guliston city government told RFE/RL that TCMIC and the Tajikistan-China Mountain Company are developing a plan to better supply the city and surrounding area with drinking water.

The official added that there are parts of Guliston that only have access to water at certain times of the day but the workers for the Chinese company living in a series of four-story buildings on Rafoqat Street have water 24 hours a day. Tajik security forces would not allow RFE/RL correspondents to enter the Chinese mining company's office building or a nearby hostel housing Chinese workers to confirm the information. The road leading to the buildings was very well maintained.

After complaints from other people living on Rafoqat Street who had a very limited supply of water, access was increased to 12 hours per day.

Cotton-Farming Woes

While forays from Chinese companies into Tajikistan's lucrative mining sector have left a trail of health and environmental concerns, so has an ambitious cotton-farming initiative involving Chinese farmers working on land in western Tajikistan's Yovon district -- just 25 kilometers from Dushanbe.

Mirzoali Azizov, the head of the Yovon district's Agricultural Department, told RFE/RL in June 2023 that the Chinese are renting 960 hectares of farmland in Yovon. Local residents told RFE/RL that in the late 2000s, when public land was allotted for agriculture, most Tajik farmers did not have the money required to buy seeds, machinery, and the other costs needed to farm and many people went to Russia to find work.

Locals said the Chinese took advantage of this situation and started leasing land in 2014.

Yovon district agricultural officials told RFE/RL that the amount of land being used by the Chinese was immense at first but later some Tajik farmers took over some of the land from the Chinese.

Both officials and local residents said the Chinese farmers have more money and financial options, such as bank loans, and can therefore use better fertilizer and farming equipment than Tajiks.

As a result, officials say Tajik farmers yield an average of four tons of cotton per hectare of land, while Chinese farmers in Tajikistan harvest nearly seven tons per hectare.

But many locals are concerned about the overuse of certain fertilizers and the lack of regulations for which and how many chemicals can be used.

The Chinese firm Agricultural Development of Tajikistan and China owns almost 1,000 hectares of land in the Yovon district while Juntai-Khatlon-Sin Silu owns 3,365 hectares of land in the southwestern Dusti district.

Saidjafar Usmonzoda -- the former chairman of the Democratic Party of Tajikistan who was a member of parliament in 2019 when the issue of leasing land to Chinese farmers was being debated -- told RFE/RL that she raised questions about which fertilizers would be used but was never given an answer despite the government approving the deal. (Usmonzoda was arrested on June 14, 2024, for "plotting to overthrow the government.")

"Couldn't the land be turned into a desert after years of overuse?" she recalled asking at the time.

Despite the concerns raised by Usmonzoda and local farmers, experts told RFE/RL that no independent research has been done on the types of fertilizers or other chemicals used by the Chinese farmers and whether or not they could have harmful effects on the land. Yovon district agricultural officials also told RFE/RL they lack the lab equipment needed to conduct such tests.

Ruzimurod Boimurodov, an associate professor of agricultural chemistry and soil science at the Agrarian University of Tajikistan in Dushanbe says that excessive use of fertilizers and pesticides is a major concern, because a large percentage of the fertilizers are not absorbed by the crop and instead go into the soil, which can cause long-term, adverse effects.

"There are delayed effects from these remaining substances and in the future they can have a negative effect on the composition, quality, and fertility of the soil and plant growth," he told RFE/RL.

Boimurodov said that according to his research, Tajik farmers typically use around 450-600 kilograms of nitrogen fertilizer per hectare or 200-260 kilograms of phosphorus fertilizer per hectare.

'A Safe Future For Our Children'

But Usmon Yatimov, a Yovon district agricultural official, told RFE/RL that according to his data, Chinese farmers growing cotton on these plots of land are using around 1,500-1,600 kilos of both nitrogen and phosphorus fertilizer.

The overuse of fertilizers and other chemicals has long been an issue in China, leading to large harvests but a decline in soil quality over time. Farmers in China have in recent years begun to cut back on fertilizers, but their application is still high compared to global averages.

Despite Tajik residents' widespread concern and complaints about polluted air, land, and rivers due to the work of Chinese companies, as well as a lack of investment in the communities the Chinese firms are working in, officials in Tajikistan continue to support these enterprises.

Many residents of the areas where Chinese firms are operating told RFE/RL that they are not against the companies, they only want them to take care of the environment and invest reasonably in the communities where they work, as the firms have pledged to do.

But due to the decrepit state of its economy and low standard of living, Tajikistan's great dependence on China and its economic resources will allow the Chinese companies to operate as they wish.

A villager who lives next to the Chinese gold mine in Khumgaron summed up the feelings of many.

"We don't want money from the Chinese -- we just want a safe future for our children."

 Chile copper, lithium mines rattled by 7.4-magnitude quake – by Cecilia Jamasmie (Mining.com – July 19, 2024)

https://www.mining.com/

A 7.4-magnitude earthquake hit northern Chile on Thursday night, 45 km outside San Pedro de Atacama, where the majority of the country’s vast copper and lithium mines are located.

The main quake hit at 9:50 p.m. local time, according to the United States Geological Survey (USGS) and has been followed by at least five aftershocks ranging from 4.2 to 5 magnitude. The seismic activity shook homes and led to power outages, but there have been no immediate reports of injuries or major damage.

Escondida, the world’s largest copper mine, jointly owned by BHP (ASX: BHP) and Rio Tinto (ASX: RIO) is one of the operations situated in the quake-hit region. Chile’s state-owned company, Codelco, also has mines in this area, including Chuquicamata, Radomiro Tomic, Ministro Hales and Gabriela Mistral mines.

USGS develops study to assess global earthquake risk to mineral supplies

Disruptions could lead to lost annual revenue of up to $1.3 billion for copper miners

GOLDEN, Colo. — A new scientific mechanism for assessing the potential risk to worldwide mineral commodity supplies from seismic activity has been developed by USGS scientists. The methodology was developed through studying copper and rhenium but provides a framework for future studies assessing many other mineral commodities around the globe.

Earthquakes have the potential to substantially affect mining operations, leading to supply chain disruptions that adversely affect the global economy. This new study quantifies that risk to copper and rhenium supply by examining the impact of earthquakes on mining, smelting, and refining operations across the globe. Many of the largest copper mines and processing facilities are concentrated in the highly seismic regions of South America, East Asia, and the Pacific with the resultant potential for cascading effects on the entire copper supply chain. Rhenium is a byproduct produced at some copper mines and therefore has similar risk.




“The potential impacts of earthquake hazards on global mineral commodity supplies have previously not been systemically quantified” said Dr. Nedal Nassar, USGS Chief of Minerals Intelligence Research.




“While our study assessed the potential for the disruption to the supplies of copper and rhenium due to earthquake hazards, this published framework will serve as a template for other mineral commodities of interest around the world,” said Dr. Kishor Jaiswal, USGS research structural engineer and lead author of the study.

Results of this study could be incorporated into economic models that would provide insights into the impacts of supply disruptions. Such analyses could be useful to national governments, mining companies, development organizations and insurance companies in making key management and business decisions.

Life Cycle of a Mine: From Planning to Rehabilitation





View the full-size infographic by clicking here.

Mining provides the critical minerals and metals needed for modern society to function. However, if these resources are not properly managed, mining activity can impact local environments and biodiversity.

For this reason, the mines of today prepare for a rehabilitated landscape right from the beginning, in a process known as “progressive reclamation”.

Today’s infographic comes to us from Natural Resources Canada, a government entity which funded the development of the Canadian Minerals and Metals Plan that supports sustainable mining practices throughout its lifecycle.
What is Progressive Mine Reclamation?

The process of progressive reclamation, also known as rehabilitation, plans for post-closure activities during the mining process, from before the first bit of dirt is moved to when the last truck leaves the mine.

There are three stages to the mining process, each with their own associated activities to plan for mine reclamation.Before Mining: Integrated mine planning for closure and reclamation
During Mining: Planning for climate change impacts and land use
After Mining: Closure and reclamation

While these are distinct stages, three continuous processes occur throughout the sequence of the mining life cycle:Continuous monitoring
Continuous engagement with Indigenous Peoples, communities, and regulators
Continuous updates to ensure closure and reclamation plans complement any modifications to the mine plan

Each process is meant to be inclusive, continuous, and responsive to the constantly changing environment to ensure there is flexibility and preparedness to adapt as necessary.


1. Before Mining

The rehabilitation process starts before mining begins. The permitting process for mine development requires closure and reclamation plans.

2. During Mining

An area of the mine can be reclaimed even as other parts of the mine are in operation. Mitigating the impacts of land disturbance during operations are critical to return the land to a viable state.

Climate change impacts can affect operations, and mine operators should account for this in ongoing processes to ensure successful closure and reclamation.

Water treatment facilities process surface and mine waters to ensure compliance, water recycling, and watershed management. This is all under the eye of continuous monitoring of the movement of earth and materials.


3. After Mining

Once the mining process is complete, mining companies can return the land to a natural state and prepare for post-closure reuse. Mine closure and rehabilitation activities need to take local environmental conditions into account. Evidence of the mining operation must be removed as much as possible.

Part of this process means the continued relationship with the people, community, and lands affected. Mining companies can re-purpose for other uses, including:Agriculture
Solar panel farms
Biofuel production
Recreational and tourist use

By incorporating local and traditional knowledge into planning and working with Indigenous Peoples and communities, modern practices and local knowledge can restore the land in a way that also brings benefits to the local community.
The Canadian Minerals and Metals Plan

Mining operations can generate opportunities for new businesses to create local benefits. Reverting mines to a rehabilitated state will ensure that the landscape can continue to support life for centuries to come.

The Canadian Minerals and Metals Plan supports this vision of progressive mine rehabilitation, to ensure Canada remains a responsible mining powerhouse for generations to come.

    Abstract

    Mycorrhizae are found on about 70-80 % of the roots of all plant species; ectomycorrhizae (ECM) are mostly found on woody plants and gymnosperms, whereas arbuscular mycorrhizal fungi (AMF) are found on 80-90 % of all plant species. In abandoned mining sites, woody plants dominate, while non-woody species remain scarce. However, this pattern depends on the specific mine site and its ecological context. This review article explores the potential of using mycorrhizae-plant associations to enhance and facilitate the remediation of mine wastelands and metal-polluted sites. In this review, we employed reputable databases to collect articles and relevant information on mycorrhizae and their role in plant growth and soil fertility spanning from the 1990s up to 2024. Our review found that the abilities of plants selected for minewasteland reclamation can be harnessed effectively if their mycorrhizae utilization is known and considered. Our findings indicate that AMF facilitates plant cohabitation by influencing species richness, feedback effects, shared mycelial networks, and plant-AMF specificity. Several types of mycorrhizae have been isolated from mine wastelands, including Glomus mosseae, which reduces heavy metal accumulation in plants, and Rhizophagus irregularis, which enhances plant growth and survival in revegetated mine sites. Additionally, studies on ECM in surface mine spoil restoration stands highlight their role in enhancing fungal biodiversity and providing habitats for rare and specialized fungal species. Recent research shows that ECM and AMF fungi can interact synergistically to enhance plant growth, with ECM improving plant nitrogen absorption and AMF increasing nitrogen use efficiency. Our review also found that despite their critical role in improving plant growth and resilience, there remains limited knowledge about the specific mechanisms by which mycorrhizae communicate with each other and other microorganisms, such as bacteria, root-associated fungi, soil protozoa, actinomycetes, nematodes, and endophytes, within the soil matrix. This article highlights the connection between mycorrhizae and plants and other microorganisms in mine wastelands, their role in improving soil structure and nutrient cycling, and how mycorrhizae can help restore soil fertility and promote plant growth, thus improving the overall environmental quality of mine wasteland sites.

    Yukon government 'ready to step in' if needed on Victoria Gold mine containment, cleanup

    Mining company's storage ponds for contaminated water are already full


    The government of the Yukon holds a briefing on the heap leach facility failure at Victoria Gold's Eagle gold mine.

    The Yukon government says it's ready to step in to "complement or supplement" Victoria Gold's work to contain the massive slide that took place last month at the Eagle mine heap leach facility.

    Speaking at a media briefing on Thursday morning, Deputy Energy, Mines and Resources Minister Lauren Haney said the company hasn't shared much information publicly about its work to remediate and contain the spill. 

    The briefing comes as experts working with the First Nation of Na-Cho Nyäk Dun are sounding the alarm on the level of cyanide contamination at the mine site.

    "It is very unfortunate and frankly unhelpful that the company has been so silent in general and specifically around the actions that they are taking on site," Haney said. 

    She said the government has been meeting regularly with Victoria Gold and receiving updates on its work. 

    "We've learned a lot more about what they are doing at site ... they're diverting water, they're collecting it," she said. 

    "That's not to say it's enough," she added.

    Containment ponds full

    Energy Mines and Resources Minister John Streicker said the mine's containment ponds for contaminated water from the slide are already full.

    As a result, Victoria Gold has started recirculating contaminated water back onto the heap, Streicker said. 

    Haney also said the mine's water treatment facility is currently unable to treat the contaminated water.

    "We are looking at all the scenarios right now and one of the scenarios is taking over activities at the site," Haney said. 

    Last week, Victoria Gold warned it might not have the money to remediate the impacts of the heap leach failure — or even reopen.

    No elevated levels of cyanide in recent water samples 

    Daily water samples are also being taken at the site and being sent to a lab in British Columbia. Results take anywhere from five to seven days to come back. 

    Samples taken from Haggart Creek earlier last month showed cyanide at a rate of 0.04 milligrams per litre, which Streicker said at the time, "could affect fish."

    Water quality samples from Haggart Creek taken on July 4, 5, 8 and 10 did not detect cyanide above current drinking water guidelines, said Tyler Williams, a water resource specialist with the Yukon government.

    Samples taken on July 5 and 10 showed detectable amount of thiocyanate, which does not have guidelines for aquatic life, Williams said. 

    The First Nation of Na-Cho Nyäk Dun also called for a halt to all mining activities on its land, where the Eagle mine currently sits. 

    "We acknowledge that his is their position," Streicker said, adding that the government is looking at the First Nation's request further. 

    He said for now, his focus is on protecting people and the environment. 

    Zimbabwe may sell 40% stake in a key gold mine to raise capital

    Zimbabwe’s state-owned Kuvimba Mining House is broadening its search for equity partners and financiers for its gold and lithium mines in a bid to raise capital and expand mineral production.


    Kuvimba could sell a 40% stake in Shamva gold mine – one of the oldest in the country – and is also looking for partners for another gold mine, Freda Rebecca, managing director Patrick Maseva-Shayawabaya said.


    “We could accept someone who could take a big chunk (of shareholding in Shamva) but not a majority stake,” Maseva-Shayawabaya told Reuters during a tour of Freda Rebecca gold mine, located about 97 kms (60 miles) north-east of the capital, Harare.

    “But we haven’t progressed enough in the discussions for us to be able to say this is the structure we envisage.”

    Kuvimba is seeking to raise about $150 million to develop an open cast mine at Shamva as well as build a processing plant. It also needs partners who can invest in extending the life of Freda Rebecca beyond the current five years, he said.

    The financing could also be secured through debt, he added. He declined to name the potential investors the company is talking to.

    The company said last month it was finalising talks with potential partners to raise financing for a lithium plant at its Sandawana mine.

    In May, one of Kuvimba’s assets, Bindura Nickel Corp, was placed under administration as it struggled to raise financing to revive production after an underground equipment failure in September halted mining operations.

    Kuvimba’s gold mines produced about 95,000 ounces of the precious metal last year.

    Vedanta pays $246 million to regain Zambia copper mines

    Vedanta Resources Ltd. has paid about $246 million to creditors to regain control of the Konkola Copper Mines in Zambia after about five years.


    The payment paves the way for “imminent reinstatement” of Konkola’s board and return of full management control to Billionaire Anil Agarwal’s Vedanta, according to a statement. The mines in the African nation hold one of the largest high-grade copper deposits in the world, as well as cobalt reserves, according to Vedanta.



    The metals and energy major plans to ramp up copper production from the mines to 300,000 tons a year and cobalt output to 6,000 tons.

    Earlier, the company settled a long-standing dispute with the Zambian government after agreeing to clear debts owed to the mine’s creditors through a court approved plan last month. KCM was put into provisional liquidation after the previous government accused its owner of lying about expansion plans and paying too little tax.

    Vedanta will turnaround the mines soon “as a world-class copper and cobalt asset that is well equipped with a smelter and a robust tailings leaching plant,” Chris Griffith, chief executive officer of Vedanta Base Metals, said in the statement.

    Zambia confirmed the payment and expects an official handover of KCM back to Vedanta next week, Mines Minister Paul Kabuswe told reporters in the capital, Lusaka.

    Agarwal, who is looking to reduce the parent company’s massive debt load, has pledged to invest $1 billion in the operation and double copper production, a move that could help shore up Zambia’s flagging copper output, which is expected to hit a 14-year low in 2023.

    Zambia asks mines to curtail normal power use by 40% amid crunch

    Zambia has asked mining companies in Africa’s second-biggest copper producer to double their power-saving efforts to 40% of normal demand, as the worst drought in decades saps hydroelectric generation.


    Zesco Ltd., the state power utility, requested operators to increase curtailments or source their own emergency power from this month, according to First Quantum Minerals Ltd., which accounts for more than half of Zambia’s copper output.

    Zesco didn’t respond to a requst for comment.

    Because First Quantum has managed to cover more than half of its normal power demand mostly from imports, that’s allowed for a reduced burden on the other mining customers to around 35%, Country Director Anthony Mukutuma said in an interview Thursday.

    “That’s really our proactive way of making sure that we are set up better for the rest of the year,” he said, adding that the company is sourcing emergency electricity mainly from Namibia and Mozambique. “If things should get worse, that way we’ve still got our direct imports.”

    While he declined to comment on whether the worsening power crisis would impact production — First Quantum in April it didn’t foresee any major interruptions — Mukutuma said sourcing more expensive power would add on average $0.06 per pound of copper to basic cash costs spread over 2024. That’s twice the impact the company saw in April.

    Copper is crucial to Zambia. The industry generates about 70% of export earnings, so the government has sought to shield mines from the power crisis. Residential electricity users endure daily power cuts lasting at least 12 hours.

    Production has so far been stable thanks to co-operation between the mining industry and the government, said Sokwani Chilembo, chief executive officer at the Zambia Chamber of Mines. So far, power imports from neighboring countries has helped prevent major disruptions, he said by phone Friday.

    “We’d have to see how things roll out into the fourth quarter,” he said. “The regional arrangements are robust for now.”

    First Quantum is also backing plans for private power companies to build renewable electricity projects in Zambia. The company plans to conclude a power-purchase agreement with a group including TotalEnergies SE for wind and solar projects that will produce a combined 430 megawatts by late 2027, Mukutuma said.

    It also looking to partner with developers of 50 megawatts of hydropower projects in parts of Zambia away from existing plants to diversify risks, he said.
