Pampa Buenos Aires
The Pampa Buenos Aires prospect is located in Region II approximately 15 km southwest of Yamana's El Peñón silver/gold mine. The 28,800 ha property is a 50-50 joint venture with Iron Creek.
The Pampa Buenos Aires is a broad plain underlain primarily by andesitic volcanic rocks but mostly covered by alluvial gravels. The Dominador fault system, which hosts Yamana's Fortuna silver/gold mine, extends southward across the Pampa Buenos Aires property. A number of zones of hydrothermal alteration occur on the mineral concessions and one highly silicified zone on the southwest of the concession block has been mined in the past for silica used as flux in smelting operations. These silicified zones are indicative of the volcanic-hydrothermal and structural history of the area.
The property was subject to regional exploration by Newmont during the period 2001 to 2003. The work included magnetometer and hoist EM surveys plus regional stream sediment sampling. Encouraging anomalous stream sediment results were obtained from areas with no history of gold mineralization. The combination of known hydrothermal systems, anomalous, previously unknown occurrences of gold and the large area obscured by the gravel cover make Pampa Buenos Aires an attractive exploration target for epithermal gold and copper mineralization.
Andina and Iron Creek have completed the drilling program and are evaluating the results for the most recent drilling and exploration program, and opportunities for this extensive land position in the prospective Region 2 Chile area.
