The absence of magnetite/hematite and the dominance of sulfides and ilmenite classify Antas North as an Iron Sulfide–Copper–Gold (ISCG) system, representing a reduced endmember within the broader IOCG spectrum. Copper mineralization at Antas North is confined to the mafic and felsic metavolcanic rocks of the Grão Pará Group and is spatially associated with calcic hydrothermal alteration (hornblende + actinolite + apatite ± allanite ± titanite). The mineralized body dips steeply southeast and trends NE–SW, parallel to the controlling shear zone. Three principal mineralization styles are recognized. Massive sulfide bodies dominate the core of the orebody and consist mainly of chalcopyrite with subordinate pyrrhotite and pyrite; relic cores of earlier hydrothermal minerals such as hornblende, actinolite and apatite are locally preserved within the sulfide mass.
