On the Bacerac property, Sierra is targeting an area of historic workings known as the San Patricio prospect, where initial confirmation sampling over an interval of 8.3 m yielded weighted averages of 2.3 g/t Au and 1,722 g/t Ag, along with significant values of copper and lead. The Company’s geologists have mapped, trenched and sampled the San Patricio area, with reported results including a 23.5 m trench length averaging 0.59 g/t Au and 200.2 g/t Ag. Mineralization is hosted by shallow-dipping breccias.
Core drilling by Sierra resulted in a low recovery of samples from the breccias zones and further drilling is planned with RC (reverse circulation) method in order to improve sample recovery from the target breccias.
