Illegal gold mining in the Brazilian Amazon has intensified in recent years, driving deforestation and raising serious environmental and health concerns. According to a 2025 report by the Amazon Environmental Research Institute (IPAM), mining-related deforestation in the region increased by 30% between 2020 and 2024, with hotspots in the states of Pará, Mato Grosso, and Roraima.
The use of mercury in gold extraction has contaminated rivers and fish, posing risks to Indigenous communities. A 2024 study by the Oswaldo Cruz Foundation (Fiocruz) found mercury levels exceeding safe limits in 60% of fish samples from the Tapajós River basin, a key area for illegal mining.
Brazilian authorities have ramped up enforcement operations, such as Operation Eldorado in 2025, which seized illegal mining equipment and destroyed airstrips. However, experts say that weak governance and high gold prices continue to fuel the illicit trade, with much of the gold being smuggled to international markets.
