The Lago Grande Complex is a PGE-mineralized layered intrusion.
PGE mineralizations occur in chromitites and associated with base metal sulfides.
U–Pb zircon crystallization age of the layered intrusion is 2722 ± 53 Ma.
Metamorphic alteration is heterogeneous and characterized by an extensive hydration.
2.55 Ga zircon ages suggest the influence of the regional IOCG hydrothermal event.
