Geology & Mineralisation
The Paranaíta Gold Project is located within a Paleoproterozoic continental magmatic arc. The local geology is characterized by oxidized, calc-alkaline I-type granites, interbedded with volcanic and volcano-sedimentary sequences, and includes minor A-type intrusive bodies. These rock types are part of a broader metallogenic framework with a genetic link between geological structures and known Au-Cu mineralized clusters throughout the Alta Floresta – Juruena Gold Province (AFGP).
Regional geophysical analysis, including 3D magnetic inversion of total magnetic intensity (TMI) data, reveals a strong correlation between structural and magnetic features and the distribution of Au-Cu mineralisation across the province. Multiple deposit clusters are spatially related to regional structures—paralleling the geological context observed at Paranaíta.
Gold (with associated copper) mineralisation at Paranaíta is primarily disseminated within granitic rocks. It is linked to syn-magmatic and syn-tectonic events, as well as overlapping hydrothermal and epithermal processes. Early-stage mineralisation is typically associated with potassic-altered granites or feldspar-rich hydrothermal rocks, featuring disseminated sulfides and gold with only minor hydrothermal overprint. This is subsequently overprinted by more advanced quartz-sericite-pyrite (QSP) alteration, which forms stockwork-style vein systems and enhances mineral concentration.
