The mineralization is hosted by Eocene dacitic and andesitic tuffs that have undergone extensive silicic, argillic and propylitic alteration. Ore deposition primarily occurs in NW\u2013SE-trending, fault-controlled quartz\u2013carbonate\u2009\u00b1\u2009sulfide veins. Based on field observations, petrography and microanalytical data, five hydrothermal stages are defined: stage I, early distal argillic\u2013propylitic alteration; stage II, the principal Cu\u2013Au\u2013Ag stage; stage III, late Au enrichment; stage IV, mineralization dominated by calcite; and stage V, supergene oxidation and secondary enrichment. Fluid inclusions show homogenization temperatures of 112\u2013331\u00b0C and salinities of 0.9\u201310.1\u2005wt% NaCl equiv.
