The recent spike in gold prices has instigated a significant mining frenzy in Brazil’s Amazon rainforest, leading to an alarming rise in deforestation within protected areas and escalating mercury pollution levels. This trend, driven by illegal mining operations, poses severe environmental and health risks, as detailed in a comprehensive study conducted by Amazon Conservation in collaboration with the Instituto Socioambiental.
Alarming Deforestation Trends in Protected Areas
The Amazon Conservation report, released in early May 2026, highlights a troubling pattern of illegal mining activities that have substantially increased deforestation rates in three conservation zones located in the Xingu region. This area is recognised as one of the largest protected forest expanses globally, straddling the states of Pará and Mato Grosso. Utilizing a combination of satellite data and on-the-ground research, the study meticulously documented the extent of the destruction.
For instance, the Terra do Meio Ecological Station, which recorded its first instances of illegal mining in September 2024, had seen mining-related deforestation expand to 30 hectares (74 acres) by the end of 2025. Similarly, the Altamira National Forest experienced a staggering loss of 832 hectares (2,056 acres) of forest cover due to illegal mining activities between 2016 and September 2025. The emergence of a new mining front in 2024 contributed an additional 36 hectares (89 acres) of deforestation by October 2025, accounting for nearly half of the total mining-related deforestation in that area for the year.
Rising Mercury Contamination and its Implications
The rise in illegal gold mining operations not only threatens biodiversity but also poses a grave risk to human health through mercury contamination. As mining activities proliferate, mercury is released into rivers, leading to the contamination of aquatic
