AMIS0285 Au 0.38g/t Cu 528ppm Greenstone Senegal
Origin of Material
This CRM is made from material supplied from the Sabodala Gold Mine, operated by the Teranga Gold Corporation. Sabodala gold mine is situated in Senega. The deposit is located within the Senegalese portion of the major Proterozoic-Birimian Kedougou-Kenieba Inlier, along the northeastern margin of the Archaean Leo Man shield. Gold mineralisation is hosted along the Sabodala Shear Zone; within
Approximate Mineral and Chemical Composition
The shear zone contains lozenges of undeformed basalt, metasediment, gabbro, and dolerite within mylonite and cataclastic breccias. Mineralization is focused in shallow-dipping to flat-lying dilational breccia zones within the shear zone. Gold mineralization is late phase and is associated with quartz, sericite, ankerite/siderite veining and orange coloured silicaalbite-carbonate-pyrite alteration. Hangingwall rocks comprise basalt and intrusive dolerite and gabbro. The primary sulphide present is pyrite with minor chalcopyrite. Gold is generally fine grained.
