Although the mine El Chanate (in Altar) and the mine Mulatos (in Sahuaripa) are distant from each other (some 400 kms), one at the border with the US in northern Sonora, the other also in Sonora, east of Hermosillo, both are gold mines, and both belong to the Canadian company Los Alamos, and both are controversial because of major disasters in recent years.
El Chanate saw a cyanid spill in 2016 (1) (5) while Mulatos saw a landslide dam in 2018 with some deaths (2)(4). That there could be a lanslide has been announced by neighbours since 2014, and there was a complaint to the National Commision for Human Rights (10). The company reacted in 2014: "Alamos Gold defended its environmental and community record at its Mulatos gold mine in Mexico following allegations of human rights violations. Mexico's human rights commission announced an investigation after residents said daily use of explosives at the Sonora state mine poses a risk to life, health and physical integrity in the Mulatos community, in Sahuaripa municipality. Blasting has damaged buildings including a church and school, while toxic residues from the mine have polluted local streams and rivers, residents said."
This company is also active in Turkey (Ida Mountain) and in Canada (Young Davidson, Kirkland Lake, Ontario).
As reported by Dulce Oilvera, there are many Canadian mining companies involved in serious environmental conflicts in Mexico, sometimes involving extreme violence against environmental defenders (as in Chicomuselo, Chiapas). (7). One of such notorious companies is Alamos Gold company in Sonora.
In 2018 there are complaints against Alamo Gold also in Micatlan, Morelos (8), because of new plans for mining.
In Sonora on 11 March 2016 the Governor announced the following investments by mining companies in the "Sonora cluster" (which includes such notorious environmental offenders as Grupo Mexico in Cananea, and also Alamo Gold). (9).
