The Cana Brava property covers an area of 31.5 km2 located in southern Ecuador.
The property hosts gold mineralization associated with altered and brecciated intrusive rocks cutting meta-volcanics and meta-sediments. Recent channel sampling by Sierramin returned assays of 7.3 g/t Au over 1.1 m. Widespread stream, silt and heavy mineral anomalies occur across both project areas. Chip samples from quartz veins and associated stockwork veins in argillically altered volcanics assayed up to 10.5 g/t Au and 30.5 g/t Ag over 0.5 m, 4.5 g/t Au and 34 g/t Ag over 0.7 m and 4.1 g/t Au and 110 g/t Ag over 1.0 m. Also, several new prospects with anomalous gold and silver values were discovered.
The property hosts a large argillic lithocap which encompasses smaller areas of high sulphidation, advanced argillic alteration which may sit above a copper porphyry system at depth. Several surface samples carrying values between 1000 and 5000 ppb gold are related to altered rhyolite porphyry dykes and bodies
