%X Analysis of gold mineralization in the Gnimi-Yabogane B zone, in the commune of Dano in southwest Burkina Faso, within the Boromo greenstone belt, reveals local geology comprising volcano-sedimentary rocks, meta-andesite, amphibolitic gabbros, and granodiorites. The study highlighted three phases of deformation (D1, D2, D3), with mineralization mainly controlled by the D2 phase, responsible for the development of NE-SW shear corridors. Deformation markers show that the D1 shear zones are sinistral and the D2 dextral, with gold mainly associated with sulfide-rich brecciated smoky quartz veins. These results confirm structural control of the Mineralization at Area B of the Gnimi-Yabogane deposit in the southwest region.
