A gold-fueled mining rush scars Brazil’s Amazon, spiking deforestation and mercury risks

Illegal miners are expanding into protected forests and Indigenous lands as mercury pollution and criminal supply chains deepen, officials and researchers say.

  • Global demand for critical minerals, used in electric vehicles and drones, is fueling a surge in illicit mining across the Amazon, intensifying threats to protected ecosystems and Indigenous territories.
  • Amazon Conservation estimates 80% of mining-related deforestation in Brazil is likely illegal, with recent studies finding illicit mining sites drove clear-cutting across three major conservation areas in the Xingu region.
  • Smugglers frequently bypass customs by mislabeling cargo or mixing minerals with iron ore, said Robert Muggah, an expert at the Igarapú Institute, adding that authorities struggle to verify the contents of shipping containers.
  • Illegal mining operations dump mercury into rivers, contaminating fish consumed by local communities; a Fiocruz study found 21.3% of fish sold in public markets exceeded World Health Organization mercury limits.
  • Humberto Freire de Barros, Amazon director for Brazil's federal police, said authorities are targeting the criminal supply chain and developing databanks to link extracted minerals to specific, authorized locations.
