Don Sixto is an epithermal low sulfidation Au-Ag deposit located
in Mendoza province, Argentina (Fig. 1). In this area, ore minerals are disseminated, in the hydrothermal quartz veins and altered volcanic-pyroclastic units of permian-triassic age (Mugas Lobos et al. 2010 and references therein). In Don Sixto, the gold resource reaches 1.258.000 ounces.
In order to characterize the argillic mineral associacion, reflectance spectroscopy analyses were performed. The analyzed samples reflected major amounts of illite and smectite with lesser kaolinite and chlorite; goethite and hematite were also recognized. In addition, buddingtonite, previously reported by Godeas and Rubinstein (2004), was identified.
