Imiter mine

The Société Métallurgique d’Imiter (SMI) is a subsidiary of Managem, which works the silver deposit at Imiter, situated in the eastern Saghro, 150 km from Ouarzazate. The silver deposit at Imiter stands out in the quality of its ore and is among the few mines in the world where silver occurs in its free elemental form and it produces ingots of Silver metal with a purity of 99.5%

Le gisement argentifère d’Imiter se distingue particulièrement par les qualités de son minerai et compte parmi les rares mines au monde où l’argent peut s’exprimer sous sa forme native et produit des lingots d’Argent métal d’une pureté de 99,5%


In late 2017, Managem completed work to extend the Imiter silver production plant, boosting the annual processing capacity by 30%. This new investment aims to prolong our mining activities and support our industrial production.


In 2018, Managem invested in the project to recycle the Imiter mine processing waste, thus promoting the environmental responsibility of its subsidiary and improving its operational performance with an 18% increase in silver production capacity as of 2019.
