The Potrerillos gold-silver project is located 8 km east of the Veladero 10 Moz gold mine and Pascua Lama Project in western San Juan Province, Argentina. The project is 100% owned by Golden Arrow and covers an area of 4575.7 ha.
Geology and Mineralization
The Potrerillos project contains three zones: Panorama, Fabiana, and Narelle. Strong silver, gold, copper, arsenic and mercury values in veins and breccias at Panorama Zone indicates the potential to discover epithermal multiphase hydrothermally altered precious metal deposits similar to Pascua Lama and Veladero. Potrerillos is underlain by Permian to Triassic volcanic and volcaniclastic rocks of the Choiyoi Group with andesitic composition in the lower part and rhyolitic in the upper portion. These rocks are unconformably overlain by late Tertiary volcanic of the Doña Ana (andesites, dacites and rhyolites) and Olivares Formation (basalts and diabases) The Doña Ana hosts the majority of the gold deposits in the El Indio Belt.
Access
Potrerillos lies in the Cordillera Frontal region, Andean Cordillera with elevations ranging from 4000m to 5000m above sea level. The main targets that have been identified to date can all be accessed by 4x4 truck and motorcycles and exploration work can be conducted 6-8 months per year.
Exploration History
1999: Grosso Group member company, IMA Exploration Inc (now Kobex Minerals Inc.) conducted a brief reconnaissance program on the property and re-visited later in same year to mid May 2000 for further exploration tasks.
2001: Three main exploration targets have been identified on the property: Panorama, Fabiana and Narelle. Most previous work was focused on the Fabiana and Narelle zones, respectively located on the western and eastern areas of the property
2010: A prospecting program targeting the Panorama Zone identified high-grade gold-silver mineralization on surface.
Exploration plans:
The company plans on completing a comprehensive surface exploration program consisting of geological mapping, geochemical sampling, IP geophysics and trenching in late 2010 to delineate targets for an early 2011 Phase 1 drill program
