Silvita

Antofagasta Region, near Taltal (Coastal Cordillera), Chile

IOCGCu

Type: IOCG prospect with tourmaline breccia pipes

Prospect near Tropezón, with at least two monolithic breccia pipes, without actinolite alteration or significant mineralization; coarse tourmaline intergrown with quartz and chalcopyrite, highly heterometric diorite fragments. Boiling recorded. Tornos et al. (2012): δ11B from -4.9 to +6.0 ‰, the widest spread of the deposits studied.
