Since the 60s there are conflicts between the Cinta Larga Indians and groups of artisan miners interested in exploiting diamond deposits in their traditional lands, an area of more than 2.6 million hectares designated by the Brazilian State as TI Roosevelt. According to studies conducted by the Departamento Nacional de Producao Mineral - DNPM, this deposits has the capacity to produce at least one million carats of diamonds. Although the Brazilian Constitution considers mineral exploitation on indigenous lands as illegal, there are bills seeking to revise it and regulate mining in this lands. The Agencia Brasileira de Inteligencia - ABIN estimates that at least 10% of the full potential of the deposit has already been removed illegally over the last fifty years.

Other comments:The first contacts between the national population and the Cinta Larga Indians happened in the early 20th century, when rubber gatherers entered in their territory. The conflict intensified in 1963, when the first prospectors began to invade their lands to decimate the indigenous population. In this year, the miner Francisco de Brito and a group of gunmen raided a village Cinta Larga and used a helicopter and dynamite to massacre the Indians. This episode became known as the Massacre of Parallel Eleven. A new slaughter occurred in 1968, when ten Indians were killed after attacking miners who invaded their territory.
