Gold deposit, hosted in a ductile shear zone and related to a mafic intrusion. The gold mineralization is hosted mainly in silty slate, dacitic cataclastic breccia and andesitic tuff breccia. Alterations are silicification, sericitization and ferrodolomitization. The mineralization diplays two episodes, an endogenetic and an exogenetic one. The endogenetic episode comprises two stages: (1) formation of dense massive quartzite through replacement of ultrabasic rocks by auriferous hydrothermal solutions, and (2) formation of small auriferous sulfide quartz veins.
