The Tucano deposit consists of a series of orebodies (TAP AB, TAP C, and Urucum) that are aligned along a N-S–trending belt and collectively contain 1.8 Moz gold of combined measured, indicated, and inferred resources at an average grade of 1.7 g/t. Cumulative past production since mine commencement in 2005 is >1.4 Moz gold.
The Tucano gold deposit is hosted in amphibolite facies, chemical metasedimentary rocks—marble and banded iron formation (BIF)—and structurally controlled by the N-S– striking, ductile Urucum shear zone. The lithostratigraphy of the Serra do Navio greenstone belt encompasses a basal package of mafic metavolcanic rocks overlain by a chemical rock sequence with BIF at the base and marbles at the top. Mining operations are undertaken at three main orebodies along the belt, namely the southern TAP AB, the central TAP C, and the northern Urucum orebodies. Gold mineralization at TAP C is made up of a series of 1- to 8-m-wide, steeply dipping, subparallel ore shoots.
