The 6.9 Moz Measured & indicated Toroparu Gold Resource forms a west-north-west oriented elongated cloud of disseminated mineralization located along the contact zone between a sequence of intermediate metavolcanics and an intrusive of tonalitic to quartz-dioritic composition.
The system, which forms a corridor that is approximately 2.7 km long, 200 m to 400 m wide, and open in depth, consists of several east-west oriented mineralized lenses:
The mineralization is hosted within a Chalcopyrite-Bornite-Pyrite-Molybdenite ore assemblage that occurs in and seems to be controlled by a stockwork of disseminated fine fractures and veinlets of dilational aspect. This mineralized corridor lies within an alteration halo of phyllic to propylitic character that represents probably several hydrothermal alteration phases. These geological and mineralogical features suggest that the Toroparu Gold Deposit is an intrusion related, possibly overprinted porphyry style, deposit.
