A surge in global gold prices, combined with sustained demand from central banks, investors, and the jewelry industry, is increasing pressure on the Amazon rainforest. Environmental monitoring groups report that illegal gold mining continued expanding across the region in 2025, affecting thousands of hectares of protected forests and Indigenous territories despite intensified law enforcement operations.
Experts say the combination of record gold prices, limited enforcement in remote areas, and the ability to move illegally mined gold into legitimate supply chains continues to encourage unauthorized mining activities.
Brazilian Authorities Target Illegal Gold Mining Operations
In November 2025, Brazilian authorities, supported by Interpol, conducted a major enforcement operation along the Madeira River, one of the Amazon's busiest mining regions.
Officials disabled 277 illegal mining dredges with an estimated value of approximately US$6.8 million.
The operation represented one of Brazil's largest recent actions against illegal river mining. However, environmental experts caution that such enforcement measures often provide only temporary disruption because mining equipment can be replaced, operations can relocate, and financial backing can shift to new areas.
Satellite Data Shows Mining Expansion Across the Amazon
Satellite monitoring indicates that mining activity continued expanding throughout the Amazon during 2025.
According to basin-wide monitoring conducted by Amazon Mining Watch, more than 37,000 hectares of new mining expansion were identified across the region during the year.
Key findings include:
• More than 37,000 hectares of new mining activity detected.
• Over 14,000 hectares located inside 222 protected areas and Indigenous territories.
• Mining in many of these locations is generally prohibited under existing environmental protections.
• A significant portion of the detected activity is therefore considered likely to be illegal.
The findings highlight the growing environmental challenges facing one of the world's most biodiverse ecosystems.
Why Illegal Gold Mining Continues to Grow
Illegal gold mining is influenced by both local conditions and global economic trends.
Several factors continue to support its expansion:
• Remote rainforest regions remain difficult to monitor consistently.
• Enforcement resources are limited across vast forest landscapes.
• Illegally mined gold can often enter legitimate supply chains through complex trading networks.
• Rising international gold prices have increased financial incentives for miners.
The profitability of extracting gold from rivers and forest areas has risen substantially as global market prices continue to reach historic highs.
Central Banks Help Strengthen Global Gold Demand
One of the major drivers of recent gold demand has been increased purchasing by central banks.
Over the past four years, central banks have acquired approximately 1,000 metric tons of gold annually, roughly double the average annual purchases recorded during the previous decade.
According to the 2026 World Gold Council Central Bank Gold Reserves Survey, 89% of participating reserve managers expected official global gold holdings to increase over the following year.
While central bank buying is only one component of demand, analysts view it as an important factor supporting strong global gold markets.
Gold Prices Reach Historic Levels
Global gold prices have climbed sharply in recent years.
Market trends include:
Year Gold Price
Approximately 20 years ago Around US$604 per ounce
Average during 2025 US$3,431 per ounce
Peak in February 2026 Above US$5,600 per ounce
The average gold price in 2025 represented a 44% increase compared with the previous year, while total global gold supply increased by only 1%.
The widening gap between demand and supply has contributed to sustained price growth.
Environmental Impact on the Amazon
Illegal gold mining affects more than mineral resources.
Environmental researchers continue to document impacts including:
• Deforestation of tropical rainforest.
• River ecosystem degradation.
• Sediment disruption.
• Increased pressure on protected conservation areas.
• Risks to Indigenous communities living near mining zones.
These environmental concerns have made illegal mining one of the Amazon's most closely monitored conservation challenges.
What the Trend Means for Global Markets
Gold remains an important asset for central banks, institutional investors, manufacturers, and jewelry markets.
As long as demand remains elevated and prices stay historically high, illegal mining operations may continue seeking opportunities despite enforcement efforts.
Analysts note that long-term progress will likely depend on a combination of stronger environmental enforcement, improved supply chain transparency, international cooperation, and responsible sourcing standards that make it more difficult for illegally mined gold to enter global markets.
