Peru is stepping up raids against illegal mining inside the Tambopata National Reserve.
Why it matters: Illegal gold mining is driving deforestation, mercury pollution, and criminal networks in a protected Amazon ecosystem. The crackdown shows Peru is escalating enforcement, but satellite data suggests miners have already pushed deeper into the reserve.
- Peruvian navy personnel and other state forces raided along the Malinowski River and destroyed dredges and camps.
- AP said the operation unfolded over several days in the week of Aug. 11, 2026.
- Officials told AP miners had already entered Tambopata National Reserve and that authorities were seeing hundreds of dredges nearby.
- Amazon Conservation said its May 12 report found more than 500 hectares of forest loss and nearly 1,000 people involved in illegal mining inside the reserve.
Peru has intensified enforcement against illegal gold mining in and around the Tambopata National Reserve in Madre de Dios, with navy personnel and other state forces carrying out raids along the Malinowski River and destroying dredges and camps used by miners. AP reported the operation took place over several days in the week of Aug. 11, 2026.
Peruvian officials told AP that illegal miners had already entered the reserve, and that authorities were seeing hundreds of dredges around the area. Deputy prosecutor Ronald Flores Yáñez said: "We can attest today that they have already entered the Tambopata National Reserve." He added: "Illegal mining is advancing close to military monitoring points and into protected areas."
The environmental stakes are high. AP reported that mercury used to separate gold from sediment has contaminated waterways, wildlife and people, including Indigenous communities that depend on fish. Peru launched Operation Mercury in 2019, which pushed illegal mining back in parts of Madre de Dios before miners shifted again toward protected areas.
Official and NGO reporting suggests the problem has deepened despite repeated interdictions. Peru's government said a July 23, 2026 operation in Tambopata destroyed goods and inputs used for illegal mining valued at more than S/ 6.6 million. Amazon Conservation said a May 12 report found more than 500 hectares of forest loss, nearly 1,000 people involved in illegal mining, and 183 active mining structures, 67 illegal camps and five major mining hubs inside the reserve. The group said mining was advancing near state control posts including Otorongo, Azul and Yarinal.
"It is particularly alarming that a significant share of the illegal mining advance is taking place inside the reserve and in areas close to control posts," said Sidney Novoa, director of conservation technologies at Conservación Amazónica-ACCA. Peru's latest push suggests officials are trying to hold the line in one of the Amazon's most sensitive protected areas.
By the numbers
- 500 hectares - forest loss inside Tambopata National Reserve, according to Amazon Conservation's May 12 report
- 1,000 people - estimated to be involved in illegal mining inside the reserve
- S/ 6.6 million - value of goods and inputs destroyed in a July 23, 2026 government operation
Yes, but: AP and the NGO monitoring both suggest enforcement has not stopped the mining footprint from expanding, raising questions about whether raids alone can reverse the incentives driving the illegal gold economy.
What's next: Peru's enforcement efforts are ongoing, with state forces continuing operations in Madre de Dios and around Tambopata.
