VETAS GRANDES

VETAS GRANDES

Highlights

• • Target: Gold/Silver Epithermal Low to Intermediate Sulphidation mineralization
  • Located in the Azuay province in the same mineralized belt hosting the Loma Larga (formerly Quimsacocha), Rio Blanco and Chaucha deposits in central Ecuador
  • Extensive surface sampling, trenching and geophysical surveys completed
  • Several large, 3m to 7m veins and quartz vein/vein breccia/stockwork forming swarm striking east-northeast over 1.4 km
  • Excellent correlation between mapped veins, rock assay results, soil geochemistry
  • Bonanza style mineralization: 3.4m trench grading 53.4 g/t Au and 641.0 g/t Ag
  • 100% Cornerstone owned, drill ready, and available for joint venture

Details

The Shyri NW concession (known as the "Vetas Grandes" property) is located in the Western Cordillera of the Andes in southern Ecuador, approximately 20 km southwest of Cuenca, the capital city of Azuay Province. The property covers a rugged area of some 23 km2 (2,300 hectares), and lies at elevations ranging from 1,500 to 3,500 m above sea level. Access to the property is good via a series of paved and/or gravel roads, and numerous mule and foot paths.

Originally acquired by Cornerstone in 2005, straddles the Gañarin Belt, a 50 km-long regional feature which contains volcanic centres and associated high-level intrusions, that is highly prospective for hosting epithermal gold - silver ± copper and porphyry copper - gold ± molybdenum deposits. Multiple, east-northeast trending low sulphidation epithermal quartz veins and vein breccias have been found measuring from 1.0 to 7.0 m in width within a zone at least 2 km long and 1.5 km wide. Mineralized veins containing gold and silver are exposed over a vertical relief of 300 m with the highest gold values localized at vein intersections and where veins outcrop around the 3,220 m elevation. Channel sampling across surface outcrops has returned 53.4 g/t gold and 641 g/t silver over 3.4 m
