The Principal and Chillo veins have a N72°W and N83°W orientation. Mineralization at the deposit is associated with three pulses of mineralizing fluids, with the last two carrying the highest gold concentrations. The characterization of fluid inclusions was carried out using petrographic techniques and microthermometry, determining the presence of primary two-phase (liquid-vapor) fluid inclusions of type L with an ovoid shape, secondary inclusions with irregular shapes, and pseudo-secondary inclusions. Where the primary fluid family is the most reliable for interpretation, with a Th of 284 °C to 315 °C and a salinity of 8.4% to 11.9% wt.% NaCl eqv.; The results obtained are very similar to the characteristics of orogenic deposits worldwide.
