The Creston Mascota deposit is approximately 1,000 metres long and four to 40 metres wide, and extends from surface to more than 200 metres depth.The host rocks at Creston-Mascota are the Frijolar Andesite and the Victoria Ignimbrite units. Generally shallowly west-dipping quartz-calcite veins and stockwork zones of mineralization associated with the Creston-Mascota deposit can be followed on the surface over a distance of 1000 metres north-south. The West Fault, first recognized during the 2008 drilling program at Creston-Mascota, is a sub-vertical, North-South striking feature against which the Creston-Mascota deposit terminates in the down-dip direction. It has been interpreted as a mainly post-mineral fault that offsets the Creston-Mascota deposit from its down-dip continuation, thought to be represented by mineralization observed at the Bravo mine/Carola prospect, located immediately southwest of Creston-Mascota. In the mineralized zone at Creston-Mascota, quartz-calcite veining is developed in the form of stockwork or as breccia (replacement and open space filling breccia sub-unit). In some locations, moderate stockwork veining, zones of silicification, and anomalous gold values also occur along the West Fault, whereas elsewhere, the West Fault consists only of nonmineralized clay gouge and breccia.
