The 2nd International Electronic Conference on Mineral Science.
The southeast region of the Amazonian Craton has been the target of several metallogenetic surveys, which recently led to the identification of the world-class Volta Grande gold deposit with gold reserves of ~ 3.8 Moz at 1.02 g/t. This deposit is loc
