Resumen:
The studied area is located at the edge between the Puna and Cordillera Oriental geological provinces, in the north-western Argentina. The district is 25 km east of Abra Pampa town, 1800 km north of Buenos Aires. North-western Argentina has a long mining history. Aguilar is the most important mine in the area and produces a Pb-Ag-Zn concentrate from an Ordovician SEDEX deposit type, with a later remobilization event produced by intrusion-related metamorphism of Mesozoic granitic plutons (Sureda, 1999). Purísima-Rumicruz has anomalous contents of Ag, As, Ni, Co, Cu and Pb, and together with La Esperanza and La Niquelina, represents a small but uncommon metallogenic province in Argentina. This province gathers together deposits of Puna and Cordillera Oriental classified as five element deposit by Lurgo Mayón (1999). Induced Polarization (IP) - Resistivity study is a well known geophysical method to determine the presence of sulfide ores, particularly hosted in vein system. IP anomalies in sulfide-rich vein deposits are considered excellent explorationguides to determining future targets for exploration.
