A geological study of the Oumjrane region (Anti-Atlas oriental) was carried out within/by the Oumjrane mining company (CMO), in order to obtain a detailed study of the two copper strands Rich Merzoug and Afilou N'Khou.
A mapping of ground was made for localization of the different facies and geological structures, with sampling of magmatic rocks, following a microscopic study.
These are dolerite, gabbro to olivine, basalt. The latter are located respectively south of the three exploited veins, Bounhass vein, Afilou N'Khou vein, and Rich Merzoug's veins.
A detailed study of the latter two veins in the second Bani Ordovician quartzite sandstone series has led to the identification of four hydrothermal stages responsible for the emplacement of the mineralization:
stage 1 to calcite siderite,
stage 2 Pyrite arsenopyrite,
stage 3 galena barite, and
stage 4 with chalcopyrite,
followed by a supergene stage due to the alteration of copper sulphides.
The Oumejerane ore deposits shows lateral zonation from SW (Cu) to NE (Cu-Pb-Ba) and (Cu-Ba), which underlines decreasing temperature from SW to NE.
