Caracterización estructural del sistema de ledges y clavos mineralizados del sector Cachinalito, mina El Guanaco, región de Antofagasta, Chile

The high sulfidation epithermal gold deposit El Guanaco is located in the Palaeocene-Lower Eocene metallogenic belt Antofagasta Region, northern Chile, 215 km SE of city. characterized by a system sub-parallel ledges made vuggy silica and quartz enargite veins. In Cachinalito sector, on north western side ore deposit, has discontinuous linear morphology, with general ENE-OSO orientation, consisting many segments that change abruptly thickness, length inclination. Grade analysis distribution, detailed mapping at scale, identification individual structures (ledges) shows one key factors genesis structural control. allowed visualizing different segmentations within structure, considering sizes, horizontal vertical continuity, degree connection between ledge orientations, as well determining orientations greater development mineralized structures. distribution grades to characterize identify shoots ledges, interpret ascending pathways mineralizing fluids dimensioning separating high- low-grade sectors. This type represents an important exploration tool helps / or production drilling this deposit.
