In a landmark cross-border operation against environmental crime, law enforcement and prosecution agencies from Brazil, French Guiana, Guyana and Suriname have arrested nearly 200 people for illegal gold mining in the Amazon region. Authorities said the operation, carried out in December, marked the first coordinated transnational crackdown of its kind in the Amazon basin and was supported by international agencies, including Interpol, the European Union and the Dutch police, which specialise in environmental crime investigations.
Officials said the large-scale action was aimed at dismantling organised networks involved in illegal gold extraction, a practice that has emerged as one of the biggest drivers of deforestation and river pollution in the Amazon rainforest. The arrests span multiple border zones, reflecting the transnational nature of the illegal mining economy operating deep inside the world’s largest tropical forest.

Environmental damage at the core of the operation
Illegal gold mining has long been identified as a major threat to the Amazon ecosystem. Large swathes of forest are cleared to make way for mining camps, while toxic chemicals are released into rivers and streams. Of particular concern is the widespread use of mercury during gold extraction, which contaminates waterways and accumulates in fish, wildlife and human populations.
Authorities said mercury pollution poses a severe health risk to Indigenous communities living along river systems, many of whom depend on fishing for survival. Long-term exposure to mercury can cause neurological damage, developmental disorders in children and irreversible harm to ecosystems.
Seizures across borders
According to Interpol, the operation led to the seizure of large quantities of cash, raw gold, mercury, weapons, narcotics and heavy mining equipment. In Guyana and Suriname alone, more than $60,000 worth of mercury was confiscated. Investigators revealed that the mercury was being smuggled across borders by concealing it inside solar panels transported on buses, a tactic designed to evade routine inspections.
Officials said the recovery of weapons and narcotics during the raids underscored the close links between illegal mining and other forms of organised crime, including drug trafficking and arms smuggling.
First coordinated Amazon-wide action
Authorities described the operation as unprecedented in scale and coordination. Until now, enforcement actions against illegal mining in the Amazon were largely confined within national borders, allowing criminal groups to shift operations across frontiers when pressure increased.
By acting jointly, Brazil, French Guiana, Guyana and Suriname aimed to close these gaps and disrupt the cross-border supply chains that sustain illegal mining, from mercury smuggling to gold trafficking and money laundering. Officials said intelligence sharing and joint planning were critical to the success of the operation.
International cooperation against environmental crime
The involvement of Interpol and European agencies reflects growing global concern over environmental crimes, which are increasingly recognised as high-profit, low-risk activities for organised criminal groups. Experts estimate that illegal mining generates billions of dollars annually worldwide, often at the cost of severe ecological destruction.
Interpol said environmental crime has become a priority area, particularly in regions like the Amazon, where biodiversity loss, climate change and criminal activity intersect. The agency added that future operations are likely to expand both in scope and geographic reach.
Focus on deterrence and follow-up action
Authorities in the four countries said investigations are continuing to identify financiers, gold traders and supply networks operating behind the scenes. Several of those arrested are believed to be low-level workers, while efforts are underway to trace the organisers and beneficiaries of the illegal trade.
Officials stressed that the operation was not a one-off exercise but part of a broader strategy to deter illegal mining and protect the Amazon rainforest. Further coordinated actions are expected, along with tighter controls on mercury trade and gold supply chains.
A signal to criminal networks
Environmental experts say the arrests send a strong message to criminal groups exploiting the Amazon’s natural resources. With international cooperation strengthening and enforcement becoming more coordinated, the cost of operating illegal mining networks is expected to rise.
As pressure mounts on governments to protect the Amazon—often described as a critical buffer against climate change—the success of this joint operation is being seen as a significant step toward safeguarding one of the planet’s most vital ecosystems.
