The Cuiú Cuiú gold project consists of several shear zone-hosted gold deposits that occur within granitic rocks of the Cuiú Cuiú Complex (2,015 Ma), in the Tapajós Region of northern Brazil. This region was the site of a major gold rush by artisanal miners from the late 1970s until the late 1990s which, according to the Brazilian Department of Mineral Production (DNPM) had a total historical production of between 20 and 30 million ounces of gold.
Cuiú Cuiú is one of the earliest garimpos in the province with the arrival of the first garimpeiros in 1958 and produced an estimated 1.5 – 2.0Moz of placer gold and was the largest placer gold area in the Tapajos.
