Abandoned pyrrhotite mine. The area is affected by acid mine drainage.
Located ca. 35 km NW of Marrakech and ca. 25 km W of the Sidi Bou Othmane locality.
The gossan was exploited for limonite and ochre from 1938 to 1963. Below the gossan, there is a cementation zone that includes native copper, pyrite, chalcocite, covellite, with traces of gold and silver. Pyrite was extracted from this zone between 1955 and 1966 and used for the production of hydrosulfuric acid for the leaching of the Cu that is contained in the chalcocite and covellite. Below the cementation zone, the primary mineralization is pyrrhotite-rich (up to 95 vol %) and it forms an elongate subvertical lens 500 m deep, 40–70 m thick, and 1500 m long.
[Note: uncertain if in Marrakech Prefecture or other prefecture.]

Most of the secondary minerals listed were detected in tailings dumps (hardpan in part).
