The Drug Cartels That Took Over Ecuador’s Gold Mines—And Why the Government Just Shut Them Down

Key Points

• Ecuador halted mining in three provinces after discovering river contamination 9,000 times above safe limits—pollution now affecting 709,000 people across two countries
• Mexican and Venezuelan cartels seized control of gold extraction, earning more from illegal mining than the government collects in legitimate taxes
• Eleven soldiers died in a May 2025 ambush, exposing how criminal organizations now outgun the state in remote territories

Something unusual is happening in Ecuador’s rivers. They’re turning colors they shouldn’t, and fish are dying in waters that sustained communities for centuries.

On February 2, Ecuador’s government suspended all mining across three provinces indefinitely. The immediate trigger: laboratory tests showing cyanide and heavy metals in southern rivers at concentrations 9,088 times above international safety limits.

But the real story runs deeper. Over five years, Ecuador’s gold sector transformed from informal family operations into a criminal empire.

Drug trafficking organizations—Los Lobos, allied with Mexico’s Jalisco Cartel and Venezuela’s Tren de Aragua—systematically seized mines across seven provinces.

In one district, they control twenty mines, extort thirty companies, and pocket $3.6 million monthly. Nationwide, illegal mining generates up to $1.2 billion annually, surpassing what the state collects legally.

Illegal Mining Violence Threatens Amazon

The violence follows the money. Last May, gunmen ambushed soldiers during an anti-mining operation, killing eleven—Ecuador‘s deadliest military loss in over a century.

Mayors opposing criminal mining were assassinated. Indigenous leaders receive death threats for defending lands where 1,740 hectares of Amazon forest vanished since 2017.

The contamination crosses borders. Rivers carrying mercury flow into Peru, where 709,000 people depend on water now poisoned by Ecuadorian processing plants.

Industry voices argue the suspension punishes 55,000 legal workers and threatens $3.3 billion in exports, demanding targeted enforcement instead.

Environmental groups counter that previous approaches failed—a 2022 ban saw mining intensify as corrupt officials leaked raid plans.

The uncomfortable truth: with only 34% of regional jobs paying minimum wage, illegal mining offers desperate people their best income. Until that changes, armies alone cannot win.

Minister Manzano promises restoration taking “many years.” The rivers cannot wait that long.
