Where is the Taraira Gold Belt?

The Taraira Gold Belt lies in the Taraira District of the Vaupés region in south-east Colombia, near the border with Brazil. Cosigo Resources holds title covering a ridge system in this district, with its Machado Project (Taraira North) as the current focus of drilling and prospecting.

Are the Machado Project, Taraira North and the Taraira Gold Belt the same project?

They are nested names. The Taraira Gold Belt is the gold district around the town of Taraira in southern Vaupés, Colombia. Cosigo Resources' Machado Project is its concession within that belt — IH3-16001X, 9,973 hectares, about 4.5 km west of Taraira. The concession includes Taraira North (Cerro Rojo, Peladero and Mata de Aji) and Taraira South (Cerro Piedra and Cerro Bomba); since 2020 Cosigo's work has focused on Cerro Rojo, and the 2024 technical report refers to the property as "Machado (aka Taraira North)".
