Peru steps up fight against illegal gold mining as activity enters protected Amazon reserve

Peruvian authorities have intensified efforts against illegal gold mining in the Amazon’s Madre de Dios region. (AP Video by Steven Grattan. Produced by Julián Trejo Bax) Updated [hour]:[minute] [AMPM] [timezone], [monthFull] [day], [year] Puerto Maldonado, Peru (AP) — Eight Peruvian Navy personnel jumped from a helicopter into a clearing carved out of the Amazon rainforest by illegal gold miners along the Malinowski River in Peru’s Madre de Dios region, sending sand and dust swirling as they ran toward the mining site. The forest gave way to giant holes gouged into the earth and filled with opaque, muddy water, gasoline and other chemicals glistening on the surface. Makeshift wooden mining platforms straddled the pools, surrounded by pumps and thick plastic tubes used to suck up and sift through sediment for tiny particles of gold.As the troops closed in, several miners stood watching from a distance. The officer leading the patrol fired a warning shot into the air. Within seconds, they vanished into the forest.The raid over several days this week was part of an intensified government campaign against illegal gold mining in Madre de Dios, one of Peru’s most biodiverse regions, as authorities try to stop the activity from advancing into protected areas of the Amazon. Mining has stripped away vast areas of rainforest, leaving behind a scarred landscape of contaminated pools and altered rivers in the hunt for lucrative gold. Mercury used to separate gold from sediment has contaminated waterways, wildlife and people, including Indigenous communities that depend heavily on fish.

Crushed beer cans and empty liquor bottles littered the ground alongside mattresses, clothes and tools. That day’s lunch — rice and plantain — still sat in plastic containers. Freezers and fuel containers dotted the camp, alongside live chickens and guinea pigs kept for food. The troops were one of eight patrols, flown by helicopter to separate points along the Malinowski River. The aircraft touched down only long enough to drop each group before lifting off and moving to the next site. 3 MIN READ 5 MIN READ 2 MIN READ Illegal mining is advancing toward protected areas of the Amazon Deforestation from illegal mining is visible in the Tambopata National Reserve in Puerto Maldonado, Peru, Tuesday, Aug. 11, 2026.

Share Edy Reynaldo Dariquebe, an official with FENAMAD, an Indigenous federation representing communities in Peru’s Madre de Dios region, said criminal groups linked to illegal mining have been operating near or inside protected Indigenous communities. He said mining is destroying forests and contaminating rivers with mercury that accumulates in fish, spreading the impact to communities far from the mining sites.Ronald Flores Yáñez, a deputy prosecutor for Peru’s Office of the Attorney General, said illegal mining has advanced close to military monitoring points and into protected areas. “We can attest today that they have already entered the Tambopata National Reserve,” Flores told The Associated Press. “We are inside the reserve and around us we see dredges numbering in the hundreds.” Peruvian Navy soldiers run as they get off a helicopter during an operation to combat illegal mining in the Tambopata National Reserve in Puerto Maldonado, Peru, Tuesday, Aug. 11, 2026.

Share Illegal mining declined in parts of Madre de Dios after Peru launched a major military and police crackdown known as Operation Mercury in 2019. But miners have since moved back toward protected areas, prompting authorities to intensify operations.Global Conservation, a U.S.-based nonprofit working with Peruvian authorities, said ongoing operations will combine satellite monitoring, aerial reconnaissance and law enforcement raids over the coming year to identify and dismantle illegal gold mining camps and equipment.Destroying the motors hits miners where it hurts most The Peruvian Navy destroys a dredge used for illegal mining near the Malinowski River in the Tambopata National Reserve in Puerto Maldonado, Peru, Tuesday, Aug. 11, 2026.

Renato Miranda told troops at a briefing that the mission’s objective was to “neutralize and dismantle” illegal mining activities. Once on the ground, that meant searching for anything that allowed the mines to function: pumps, batteries, fuel, dredging equipment and makeshift infrastructure. “The most important thing is to destroy the main machinery,” Miranda said. “And the main machinery is the motors.”The powerful engines are among the most valuable pieces of equipment at a mining site and a key economic pressure point for authorities trying to make it more expensive for miners to restart operations. Miranda said larger engines can cost around $30,000 to $45,000. He estimated that motors targeted in the raids can extract 30 to 50 grams of gold a day. At current gold prices, that would be worth about $4,000 to $7,000.

Share Miranda told AP the three-day operation destroyed 56 motors, 78 mining rafts and 13,751 gallons (52,050 liters) of fuel, with the destroyed material valued at more than 15 million soles ($4 million). On the ground, soldiers said they had destroyed around 115 motors over the previous three months during operations carried out nearly every week. The remote sites give miners time to hear approaching boats or helicopters and flee, often hiding motors in sand, behind trees or in muddy pools to recover later. Specialized navy divers search the murky pools for submerged engines, entering water where mercury and other chemicals may be present. When they find one, they attach explosive charges and destroy it.At one site, as troops prepared to leave, a soldier spotted disturbed sand and began digging. He uncovered a motor, threw it onto a pile with a mattress and chainsaw, doused it with gasoline and set it alight. A dog abandoned at the site fared better: soldiers took a liking to it, bringing it along for the rest of the day’s mission and eventually back to their military base.Elsewhere, troops used dynamite-like explosives to destroy equipment and burned structures and supplies that could be used to keep the mining camps running.

Share A 10-minute boat ride away, another, larger camp offered a glimpse of daily life at the mining sites. A chest freezer was packed with meat, while wooden shelves held plates and coffee mugs. Several separate sleeping areas were strewn with personal belongings: a ledger filled with lists of needed supplies, freshly washed underwear hanging from string to dry, bottles of vitamins and even pills marketed as increasing penis size and sexual endurance. All was set alight by the troops. Before moving on, some of the soldiers cooked and ate food they found in the abandoned camp.The expensive machinery and valuable gold contrasts with the precarious conditions of many living and working in the camps.During the operation, another patrol encountered a woman with her 1-year-old child at a mining site. Flores told AP she had come to Madre de Dios from Cusco after failing to gain admission to university and, after being left by the father of her child, needed work. She responded to an seeking a cook and ended up preparing food for illegal miners.Authorities say raids alone will not stop the mining A Peruvian Navy soldier walks over a pipe to get to a dredge used for illegal mining near the Malinowski River in the Tambopata National Reserve in Puerto Maldonado, Peru, Tuesday, Aug. 11, 2026.

Share The destruction of machinery is intended to hit miners where it hurts most: the cost of restarting. But authorities themselves acknowledge that raids alone are not enough.Miranda said that with gold prices high and mining highly profitable, operators can acquire another engine, rebuild their equipment and return to the same location or move elsewhere.“Every day they are advancing more and more and more, and we are being very slow,” said Flores, adding that their strategy needs to change.

Share Prosecutors, he said, are now pursuing two fronts: continuing operations against dredges, motors and other equipment while also following the money behind the mines — identifying the financiers who provide the capital for expensive machinery and tracing the profits generated by the gold.That approach could be critical to breaking the cycle visible along the Malinowski River: authorities destroy equipment, leave and miners find the money and machinery to start again.“These operations have to be permanent,” Flores said.
