In a landmark multinational law enforcement operation, police and prosecutors from Brazil, French Guiana, Guyana, and Suriname have conducted their first coordinated transnational strike against illegal gold mining networks. The operation, dubbed ‘Guyana Shield’ and executed in December 2025, resulted in 198 arrests and significant seizures of contraband across the region.
Coordinated through INTERPOL with support from the European Union’s EL PACCTO 2.0 program and the Dutch Police’s High Impact Environmental Crime team, the operation deployed over 24,500 checks on vehicles and individuals across remote border areas. Among the most significant apprehensions were three men detained in Guyana on suspicion of gold smuggling and money laundering. The suspects, allegedly connected to a major organized crime group with possible ties to a prominent Guyanese gold exporting firm, were intercepted carrying unprocessed gold and USD 590,000 in cash.
The operation yielded substantial environmental enforcement breakthroughs, particularly with the seizure of mercury cylinders valued at over USD 60,000 in Guyana and Suriname. The toxic substance, commonly used in illegal mining operations to separate gold from other metals, was discovered concealed within solar panels during transport by bus. Mercury contamination represents a severe ecological and public health threat in the environmentally fragile region.
Innovative ‘mirror operations’ saw officers from neighboring countries conducting simultaneous checks on opposite banks of border rivers Oyapock and Maroni. These coordinated efforts targeted small riverside stores known to supply mining equipment and facilitate gold smuggling operations. Inspections resulted in the confiscation of counterfeit medicines, alcohol, and cigarettes worth over USD 40,000, marking the first transnational police deployment of its kind in the area.
Additional seizures included mining equipment such as pumps and gold-trapping mats, firearms, communications devices, and the interception of a bus carrying undocumented migrants. Several minors aboard were suspected victims of child labor or sexual exploitation networks.
INTERPOL Secretary General Valdecy Urquiza highlighted the global context: ‘The surge in international gold prices in recent years has made illegal gold mining the fastest-growing revenue stream for organized crime groups, including in Latin America. At INTERPOL, we are committed to working with our partners to disrupt those networks and prevent more damage to this remote and environmentally fragile region.’
