Rio Grande is a large porphyry copper-gold prospect with associated IOCG (iron-oxide-copper-gold) style alteration located in Salta Province, northwestern Argentina. Copper-gold mineralization at Rio Grande occurs within the eroded central core of a mid-Miocene intrusive center and is best expressed by a large area (2 km by 2 km) of well-defined, coincident copper-in-soil, gold-in-soil, and induced polarization (IP) chargeability anomalies. Trenching and drilling programs by Teck Corporation (2000-2001), Antares (2004-2008) and Regulus (2010-2012) have partially delineated the Discovery and Sofia copper-gold zones along the southeast margins of the system, extended the known mineralization to the northern and western margins of the system, and also encountered indications of deeper copper-gold mineralization beneath the central portion of the system.
