The mineralized deposits at the Manantial Espejo mine are predominantly veins with short strike slip and larger down dip displacement. The styles of mineralization include massive quartz veins, vein breccias, sheeted and stockwork veining, and minor dissemination. Gold occurs mainly as electrum in pyrite while the silver occurs in a number of forms including argentiferous galena and silver sulphosalts. Sulphides account for up to 3% to 5% ocount for up to 3% to 5% of the rock mass as veinlets and dissemination. Mineralization at Manantial Espejo is hosted in four main veins known as Maria, Karina/Union, Melissa, and Concepcion. The majority of the mineralization out lined to date is in the Maria Vein. The vein is a thick silica vein exposed on surface fot more than one kilometre and has been intersected at a depth of up to 275 metres. This vein averages 7.8 metres in true wight and ranges from 0.63 metres to 20 metres and is open to the east and at depth. Economic grade mineralization of the vein is less continuous. Open pit economic grade zones measure tens to hundreds of metres in longitudinal dimention, with over 100 metres of vertical extent in the Maria West area.The Karina/Union Vein is exposed on surface for a distance of 850 metres and has been drilled to a depth of 150 metres. Several interconnected high grade silver-gold epithermal veins in excess of 20 metres true wights have been observed in drillhole intersections.The Melissa vein is thought to be the extensional component to the Maria shear system. The Melissa Vein has been defined by drill hole along a 300 metres strike lenght and 200 metres down dip and averages from between 1.5 and 2.5 metres wide.The Concepción Vein is a single quartz vein. Mineralization occurs over a strike lenght of 600 metres and is open at depth and at both ends. The host rocks mineralogy and alteration are similar to the other veins on the property.
