Caballos-oct2016 Location Map

Golden Arrow's prospect generator activities are focused on identifying, acquiring and advancing precious and base metal projects with the potential for world class discovery. Golden Arrow seeks to leverage the Company's exploration exposure by attracting partners to fund work on its high quality mineral projects, such as Caballos.

Drill-ready project prospective for large porphyry copper-gold, and epithermal gold-silver deposits

The Caballos Copper-Gold Project covers over 12,000 hectares of a prospective porphyry copper and epithermal gold-silver district along the Chilean border in western La Rioja Province, Argentina, and was discovered and staked by Golden Arrow's technical team. An initial multi-discipline exploration program led to the discovery of a large copper-gold porphyry target, including a magnetic core measuring 300m x 800m. Outcrop sampling on the margin of the magnetic core zone encountered 12 metres averaging 2.4% copper within an 18 metre continuous chip sample. The coincidence of magnetic high, chargeability high, elevated gold and copper geochemistry and classic porphyry alteration combines to present a compelling copper gold porphyry drill target.

Strategically located in at intersection of two world-class mining districts

The property is located in a developing porphyry district at the intersection between the south end of the Maricunga Copper-Gold Belt with the northern extent of the El Indio Gold-Silver Belt. Advanced projects in the area include El Morro (65km SW with proven and probable reserves of 5.84 Moz Au & 4.36 Blbs Cu 1), Los Helados (22km to SW with indicated resources of 10.34 Blbs Cu, 6.65Moz Au & 52.40Moz Ag2) and Caserones (21km to the NW with 1.3 billion tonnes copper-moly3) on the Chilean side of the border and Josemaria (25km SW with indicated resource of 5.43 Blbs Cu & 5.5Moz Au2) and Filo del Sol in Argentina (38km to SW with intercepts including VRC 28 with 222m of 0.66% copper2).

The Caballos property is located in the Andean Cordillera with elevations ranging from 4,000m to 4,500m above sea level. A paved highway and good gravel roads allow easy access to the eastern part of the property and work can be conducted for 7 to 8 months of the year. The nearest small community is 100km away.

Project Geology and Exploration Summary

In 2012 Golden Arrow discovered a large copper-gold porphyry target at Caballos, through the completion of a surface exploration program including an IP/Resistivity geophysical survey, a detailed ground magnetic survey, geological mapping and additional surface rock and talus fine geochemical sampling. The magnetic core zone of the interpreted porphyry system measures 300 m by 800 m. Sampling on the margin of the magnetic core survey encountered 12 metres averaging 2.4% copper within an 18 metre continuous chip sample, and a nearby hand trench produced a composite chip sample that averaged 0.60% copper and 0.35 g/t Au over 5m (see news release dated December 5, 2011).

The magnetic core of the interpreted porphyry system, as defined by the detailed ground magnetic survey, is largely covered by talus. The IP/Resistivity survey, conducted by Quantec Geoscience, shows a large chargeability high that closely correlates with the interpreted magnetic porphyry core.

Talus fine sampling on the southern half of the porphyry target defined an 1100m by 400m area with elevated with copper geochemistry (+50 ppm Cu envelope with a high of 1667 ppm Cu) and, in an overlapping but slightly reduced area, a gold geochemical anomaly (+20 ppb Au envelope with a high of 149 ppb Au), both centered on the quartz--magnetite stockwork.
