The Minaspampa project was explored for 4 years between the period of 2007 to 2014. A total of 23,975 surface (soil) samples, and 414 drill holes for an aggregate of 53,224m were undertaken between 2008 and 2012 on the Minaspampa property. Also, geophysics over 44 km was conducted.
As per the NI43-101 report, the area is underlain by Mesozoic sediments of the West Peruvian Basin. Regionally, exposed rocks are dominated by Upper Jurassic Chicama Formation to Lower Cretaceous Goyllarisquizga Group. These rocks are composed primarily of siliciclastic sediments with lesser amounts of carbonate sediments. They are highly folded and faulted by Cenozoic deformation events. To the west, Calipuy Group volcanics of the Tertiary unconformably overlay the Cretaceous sediments (Garay et al., 2014). All formations are cut by series of Calipuy Group subvolcanic intrusions aligned in a north-south orientation. Finally, glacial and fluvial sediments were deposited during the Quaternary.
The geology of the Minaspampa property is controlled by regional Andean structural regimes. There are two major fault systems present in the area: northwest southeast longitudinal systems and northeast-southwest transverse systems. The longitudinal northwest-southeast faults are the result of regional compression, forming graben-horst blocks and uplift. Structures associated to these major faults include hydrothermal breccia, tectonic breccia and milky quartz veinlets.
