The Productora Cu-Au-Mo deposit: an example of spatially associated magnetite-apatite, tourmaline-cemented breccias and porphyry mineralization

The Productora Cu-Au-Mo deposit is hosted by a Mesozoic hydrothermal breccia complex in the Coastal Cordillara of Region III, northern Chile. Mineralization at Productora extends discontinuously over 8 km in a northeast-oriented corridor. The current resource, which includes the neighboring Alice porphyry Cu-Mo deposit, is estimated at 236.6 Mt grading 0.48% Cu, 0.10 g/t Au, and 135 ppm Mo. The deposit is of significant interest as it presents an example of spatially associated magnetite-apatite mineralization and porphyry-style mineralization. Whilst previous studies have described Productora as an IOCG, we describe the deposit characteristics, based on new information, and present a revised genetic model. Discussion is centered around fluid source and deposit classification as porphyry-related rather than IOCG.
