Brazilian Federal Police and the federal environmental agency Ibama said they destroyed 22 dredges used in illegal gold extraction and five vessels used for logistical support during a joint operation on the Madeira River in the Amazon state of Amazonas.
Operation Hidra Dourada took place between September 21 and 25, 2026, in a stretch of the river between the municipalities of Autazes and Novo Aripuanã. The agencies reported carrying out 18 enforcement actions.
What happened
According to the Federal Police, the operation targeted illegal gold-mining activity along the Madeira River. Authorities said they destroyed the 22 dredges and five support vessels during the action.
The agencies also recorded two violation notices, 17 seizure records and 18 destruction records. Officers seized a 9 mm firearm, ammunition and three mobile phones, the Federal Police said.
The police said the seized materials would support ongoing investigations into the economic and logistics chain sustaining the activity and would help deepen those inquiries.
The official disclosure did not identify any alleged operators, vessel owners or suspects. It also did not announce arrests, criminal charges, court proceedings or judicial findings.
Why it matters
The operation illustrates the enforcement approach being used against illegal gold extraction in a major Amazon waterway: joint action by criminal investigators and environmental authorities, combined with the destruction of equipment that officials said was used in the activity.
But the action remains at an administrative and investigative stage. The reported destruction, notices and seizures do not establish criminal responsibility for any individual or company. The Federal Police has said only that the materials collected will be used in ongoing inquiries into the network that provides economic and logistical support.
The bigger picture
The Madeira River operation was conducted by two federal bodies with distinct roles. The Federal Police is responsible for investigating potential crimes, while Ibama is Brazil’s federal environmental enforcement agency. Their joint deployment enabled authorities to report both enforcement records and the seizure of materials intended for investigative use.
The information released by the Federal Police focuses on assets and administrative records rather than named people. As a result, it does not establish who operated the destroyed equipment, who owned it, or whether any person will ultimately face an accusation or prosecution.
Independent reports cited in the verified material repeated the official figures, but the available corroboration appears to rely substantially on the Federal Police disclosure rather than separate field verification.
By the numbers
- 18: joint enforcement actions reported by the Federal Police and Ibama.
- 22: dredges authorities said were destroyed.
- 5: support vessels authorities said were destroyed.
- 2: violation notices recorded.
- 17: seizure records recorded.
- 18: destruction records recorded.
- 1: 9 mm firearm seized, along with ammunition and three mobile phones.
What happens next
The Federal Police said the firearm, ammunition and phones will support its ongoing investigation into the activity’s economic and logistics chain. The release did not provide a timetable for further investigative steps or say whether suspects had been identified.
Any future arrests, charges or judicial decisions would represent separate procedural stages. None was announced in the cited disclosure.
