Search Brazil’s environmental agency identifies ‘signs of violations’ by mining company near Indigenous territory Dead river dolphins and turtles were found in a river in the Waimiri Atroari Indigenous Territory; Ibama says ‘areas of exposed soil and mineral extraction’ extend beyond Mineração Taboca’s authorised area; company denies any link between its operations and water contamination By Isabel Harari | Editor Carlos Juliano Barros 28/05/2026 16:11 + IBAMA (Brazilian Institute of Environment and Renewable Natural Resources) has identified “signs of environmental violations” in a mining area near the territory of the Waimiri Atroari people, in Amazonas state. Between April and May, Indigenous people said they found dead animals, including Amazon river dolphins and turtles, in rivers that run through the Indigenous territory. They suspect that waste from Mineração Taboca’s operations, Brazil’s largest producer of refined tin, may have polluted the waters in this part of the Amazon. “Visual evidence obtained through remote sensing confirms that the mining front and the associated environmental degradation are advancing towards the immediate boundary of the Waimiri Atroari Indigenous Land,” states a document sent on 19 May to the Federal Prosecutor’s Office in Amazonas (MPF-AM), which is investigating the case.
