Imider is the biggest mine on the African continent, and 7th largest producer of silver in the world. It is also home to a 5-year long fight (preceded by decades of mobilizations), as a group of protesters has been living on Mount Alebban, about 300km east of Marrakesh, since August 2011. The mine is run by Societe Metallurgique d'Imider (SMI), founded in 1969. SMI started extracting silver in 1978. Some protests took place in 1986 against the digging of a well which would have had a negative impact on local inhabitant and farmers. Leaders of the protest were imprisoned and wells were dug, to the detriment of the local community.
