Molybdenum mine.
One of the rare Mo-W-Cu exploited skarns (three historic mines).

Located 15km SW of the village of Amizmiz.

The regional geology of the Azegour area is marked by a lower Cambrian volcano-sedimentary series consisting of lava flow and pyroclastites, which are sandstone–mudstone rocks interlayered with volcanic and pyroclastic rocks. It also consists of limestone bars and lenses interbedded with thin pelitic, volcanic, and pyroclastic bands or lenses, as well as andesitic flow in intercalation with pelite and volcanic lies. The middle Cambrian is essentially composed of sandstone and pelite. The Cambrian sequences are unconformably overlain by the Cretaceous–Tertiary sub-atlanic formations. The magmatic activity of Azegour is linked to its volcanic arc context, and previously to the Cambrian extension. This magmatic activity is a continental intra-plate tholeiite, as widely described in the lower Moroccan Cambrian. During the magmatism of late Hercynian orogeny, small plutons of granite, granodiorite, including the intrusive rocks of Azegour, and other felsic rocks were formed. The Azegour pink granite outcrop has an elongated form and extends NNW–SSE; it is about 7 km long and 1 km wide, representing a stock that is inclined to the southeast. This Azegour intrusion has a Permian Rb-Sr age (271 ± 3 Ma). From a chemical point of view, the granite is a K-calc-alkaline hyperaluminous granite of crustal origin (S-type granite). The calc-alkaline granites of Azegour are associated with the molybdenum granite type.
