SAV'OR-CI's semi-industrial mine is located in Groudji, (Djékanou department), in the central-eastern part of Côte d'Ivoire, in the southern part of the Oumé-Fétékro birimian greenstone belt (West African craton). The Birimian terrains was affected by multiple deformation and mineralization events. This study is a contribution to resolve some issues in the Bririmian such as the improvement of petrography and knowledge. The methodology is on macroscopic to microscopic observations. The lithology of SAVO’R gold mine consists of four major units. The first unit, volcanic, made of volcanic lavas (metabasalt and rhyodacite) and volcaniclastics (mafic tuffs and felsic volcaniclastics). The second unit is a plutonic rocks which is summarized by metagranodiorites and granodiorites. The third unit which outcrops in the form of vein is represented by aplites and microgranites. The last unit is composed of metamorphic rock, precisely gneisses. The presence of lavas, and volcaniclastics reveal respectively that the effusive volcanism and the explosive volcanism have occurred during the setting of area rocks. All lithologies have been affected by hydrothermal alteration marked by quartz veins and veinlets, feldspars, carbonates, often associated with sericite, chlorite and sulphides. Gold is not visible to the eye in the observed lithologies. These rocks are affected by a metamorphism of greenschist facies marked by the presence of chlorite, sericite and epidote minerals.
