As cocaine prices fall and gold prices climb, organized crime is expanding illegal gold mining across the Amazon—fueling mercury pollution, violence, and new U.S. policy debates.
Runashitu, a small Indigenous village along Ecuador’s Napo River, has long been shaped by the rhythm of the rainforest—until illegal gold mining changed the pace, and residents began measuring safety in what they can no longer rely on: clean water, stable food, and freedom of movement.
For decades, Nely Shiguango says her Kichwa community could walk about without fear.. In recent years. she describes a cascade of harms that local people link directly to a boom in illicit mining nearby—declining arable land. more illness. and a sharper wave of kidnappings and killings.. In Napo province. homicides climbed to 19 last year. nearly double the 2024 figure. underscoring how quickly environmental extraction can morph into organized violence.
The shift also reflects a broader economic logic driving criminal networks across the Amazon.. As illegal gold production expands. the trade has become lucrative enough to compete with—at times eclipse—the illegal drug market.. One assessment described the value of illicit gold across South America as reaching as high as $12 billion annually by 2023.. Another finding argues that illegal gold now can generate more money than cocaine trafficking in parts of the region known for drug production. particularly when the price dynamics favor gold and when enforcement is harder.
That combination—rising gold prices and shifting enforcement realities—is part of why cocaine is no longer the only business model.. Experts point to falling cocaine values in some markets while gold prices have surged. creating stronger incentives for groups to diversify.. There’s also a practical risk calculation at play: gold, unlike cocaine, is not inherently illegal as a commodity.. That distinction matters when investigators try to prove illegality in court.. If law enforcement intercepts gold. the challenge becomes not just seizure. but proving it was sourced through forced labor. unlawful land encroachment. or environmental crimes.
The consequences land first on Indigenous communities and workers living at the edge of the rainforest.. Shiguango’s account is grounded in day-to-day change rather than abstract policy.. She says armed and illegal operations don’t just damage ecosystems—they pollute rivers and food. then fracture social life through intimidation and threats.. She describes authorities being bribed to look away. and she says her own activism has drawn threatening calls so frequently that walking freely in the street is no longer guaranteed.
Mercury is one of the most visible and deadly links in that chain.. In many illicit extraction sites, mercury can be used to help separate gold from ore.. The process contaminates waterways as vaporized mercury settles in soil and rivers. then moves through fish and drinking water—setting up mercury poisoning risks that can surface as serious health problems.. Shiguango says mercury has shown up in blood tests within her community and that illnesses and deaths have increased. including young people she suspects are being harmed by exposure.. Her descriptions—headaches. memory issues. and severe illness in early adulthood—are not simply grim anecdotes; they mirror what happens when a profit-driven supply chain externalizes its costs onto communities with the fewest resources to manage contamination.
This is where the story becomes more than an Amazon problem.. Illicit gold can be laundered to look legitimate before it reaches buyers. including through international trade routes that help obscure origin.. That makes it difficult to track the real scale of the illegal trade.. Yet there are signals that the United States has a direct stake: Colombia is cited as exporting large volumes of gold. and the United States is described as a leading importer.. If the supply is tainted upstream. downstream demand can become a vulnerability for enforcement systems—especially when provenance rules are weak or inconsistent.
Across the region, governments are responding with a mix of crackdowns and regulatory gray areas.. Peru’s framework for informal mining—registered under a system often described as an extended list used to manage formalization—has been criticized by experts as creating a legal “in-between” that can slow or complicate criminal charges.. Even when penalties are tightened, temporary permits can return, which can frustrate efforts to shut down illicit sites quickly.. Meanwhile. coordinated regional mechanisms are forming: Brazil is expanding the use of forensic techniques that analyze the isotopic structure of seized gold to estimate geographic origin. and Amazon-area partners are building cross-border tools aimed at criminal networks.
For U.S.. policymakers, the question is how to translate these realities into enforcement that can actually disrupt money flows.. In Washington. lawmakers have introduced a strategy-focused proposal—centered on international coordination to fight illicit gold mining in the Western Hemisphere.. The broader debate is also shifting toward customs and declaration rules.. Advocates argue that current declaration requirements are not strict enough for gold compared with cash and monetary instruments. meaning travelers carrying substantial quantities of gold may face uncertain legal consequences.
If the pattern holds. gold may continue to rival drugs not because it is safer. but because it is easier to hide—until the paperwork and proof hurdles catch up.. That’s the operational challenge facing regulators and investigators.. It also raises a future policy question for the U.S.: whether enforcement will prioritize not just seizures. but provenance—tracking how illegal mining. mercury exposure. land theft. and violence intersect with international trade.
Shiguango frames the choice in moral terms as much as political ones.. She has traveled to speak on Indigenous issues at the United Nations. describing contamination. displacement. and recruitment of youth into criminal structures.. Despite the threats, she says she believes the work must continue.. If pressure and disclosure fatigue set in. the rainforest—and the people who depend on it—could pay the price for a global market that treats the harm as an invisible cost.
