Strategic location in the prolific El Indio gold-silver belt
The Potrerillos gold-silver project is located in the world-class El
Indio gold silver belt, just 8 km east of Barricks' Veladero gold mine
and Pascua Lama project in western San Juan Province, Argentina. Golden
Arrow has an exclusive right to the 3,999 hectare property.
Under-explored epithermal gold-silver target with multi-million ounce potential
The Panorama Ridge target hosts a structurally-controlled, outcropping
mineralized quartz-calcite vein system traceable for 3 kilometres. Rock
chip sampling returned samples with as much as 15 g/t gold and 2995 g/t
silver. 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. The target is underexplored, with
only 508 metres of drilling in 3 holes.
Multiple additional drill-ready targets.
In addition to Panorama ridge, Golden Arrow has identified the drill
targets Copper South, Fabiana and Narelle. Drill permits are in place.
Potrerillos lies in the Cordillera Frontal region, Andean Cordillera with elevations ranging from 4000m to 5000m above sea level. The Potrerillos project contains three zones: Panorama, Fabiana, and Narelle. 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.
The Panorama Ridge LS epithermal gold silver target is controlled by
the intersection of major fault systems. The dominant feature is a NS
orientated thrust system where Permian to Triassic rhyolites of Choiyoi
Group are thrust from east to west over the Doña Ana andesites of
Oligocene-Miocene age. The Doña Ana hosts the majority of the gold
deposits in the El Indio Belt.
Large (up to 15m thick) calcite quartz veins have developed along this
NS thrust system and are traced for 3km. The mineralization in the
thrust veins is variable, very high grades occur in some zones but
generally with silver around 20 to 50ppm and gold 0.1 to 0.2 ppm.
Cross cutting the major NS thrust are a number of east --westerly faults
that control mineralization at the Valedero mine. At the intersection
of the NS Thrust and WNW Faults a system of quartz vein stock works
occur, with veins up to 2m thick and grades up to 15.4 g/t Au and 844
g/t Ag.
In 2010-2011 Golden Arrow completed a significant exploration program, including:
