Vares, Bosnia Confronts Lead Poisoning Fears After Mine Reopens

Lead Contamination Concerns Following Mine Reopening

By Amel Emric and Daria Sito-Sucic

VARES, Bosnia and Herzegovina, May 6 (Reuters) - A new silver, lead and barite mine offered hope to the small town of Vares, in mountainous central Bosnia, when it opened in 2024. After decades of economic decline, new roads and houses were built, cafes and restaurants filled up, and the long-dwindling population swelled with workers and new residents.

In recent months, however, blood tests have revealed exposure to lead in more than 300 residents living near the mine, some at elevated levels, alarming locals and throwing the town's future into doubt.

Legal and Environmental Response

On Wednesday, four Bosnian environmental agencies filed criminal charges against Dundee Precious Metals, the Canadian mining company that took over the mine in September when it acquired the previous owner, UK-based Adriatic Metals, with the Zenica-Doboj cantonal prosecutors' office.

"We think that the situation is ripe to declare an emergency situation," Miroslav Pejcinovic, the president of Opstanak (Survival) Vares, one of the agencies, told Reuters. "Somebody needs to take responsibility."

Toronto-listed DPM denies responsibility, but recognises there is a problem.

Blood Testing and Results

The company agreed to finance blood tests in December. The residents said they asked for the tests because the mine's previous owner had offered to conduct them, not because there were any signs of harm. Still, the results showed 17 of 44 people who lived close to the mine's processing plant and waste depot had elevated lead levels in their blood.

Subsequent rounds of tests conducted by health institutes in the cities of Zenica and Sarajevo showed that more than 300 people, including some living further away from the mine in Vares, also had lead in their blood. 

Health Implications

Elevated lead levels can damage the nervous system and the brain and cause learning difficulties in children. So far, residents and the organisations said that there was no sign yet of harm from the lead exposure, but doctors say any level can be dangerous.

The Vares health centre said in a report in March that the test results did not show signs of acute lead poisoning, but rather indicated long-term exposure to different possible environmental factors of low intensity.

According to the report, of 238 blood tests conducted by the Zenica-based Institute for Health and Food Safety, 23% were seen above a danger threshold of 2.8 micrograms per decilitre of blood and 13% were above 5 micrograms per decilitre.

Uncertainty Over Source of Contamination

Local officials said such widespread tests had not previously been conducted, so it was not possible to determine if the lead came from the new mine or was due to decades of previous mining activity in the area, which is rich in metals. 

Further Environmental Testing and Official Actions

Testing of Water and Land

FURTHER TESTS OF WATER AND LAND

DPM joined a working group formed by town officials and physicians after the first test results in December. The group has initiated tests of land, water, agricultural produce and dust in areas surrounding the processing plant and waste depot.

It told Reuters in a statement that it took health and environmental matters seriously and was working with authorities.

"We believe that issues relating to the environment and public health should be assessed on the basis of expert analysis, verified data and through the appropriate institutional procedures, without prejudging responsibility before the relevant processes have been concluded," it said. 

Government and Legal Proceedings

Charges were also filed on Wednesday against cantonal and regional government ministers, whom the environmental organisations accuse of failing to do enough to protect residents. The charges will now be reviewed. If accepted, the case will likely go to court. 

The government of Bosnia's Bosniak-Croat Federation, where Vares is located, says it is trying to find a solution and has announced the formation of an expert group.

"We need to monitor the situation and take appropriate measures when it escalates," Federation Prime Minister Nermin Niksic said on Monday. "The peoples' health cannot be endangered because of someone's negligence, or someone's investment or someone's interest." 

Impact on Local Residents

The Ahmedovic Family's Struggle

'LIFE IS NOT EASY WITH LEAD'

The Ahmedovic family, who live near the mine's processing plant, have been faithful to Vares amid its economic ups and downs, investing in cattle and crops just as others moved away.

Now they might move too after the family, including two children, tested positive for lead. The metal was also detected in their croplands, forcing them to halt sowing wheat, vegetables and fruit.

"I am not even sure if there is lead in this hay," the mother, Enisa Ahmedovic, said recently while feeding cows on her property. "Life with lead is not easy."

Community Demands for Accountability

For now, residents want answers. 

"We don't know who is to blame," said Emina Veljovic, an expert in environmental law at the Aarhus centre in Bosnia, adding that the authorities must determine "who poisons children, who poisons our citizens."

Key Takeaways

  • The Vareš region has a long legacy of mining activity dating back centuries, and the current mine—operational since 2023‑2024 under Adriatic Metals and acquired by Dundee Precious Metals in September 2025—is one of Bosnia’s largest foreign investments (en.wikipedia.org).
  • Health experts stress there is no safe blood lead level; even low-level exposure (<5 µg/dL) can impair cognitive development in children and kidney or cardiovascular function in adults (niehs.nih.gov).
  • Legacy contamination from decades of mining across the Vareš area complicates attribution; environmental groups seek remediation amid uncertainty whether recent or historic operations are to blame (balcanicaucaso.org)
