Canadian firm Goldcorp is the largest gold miner in Mexico, with mining concessions covering more than 40,000 hectares. Since 2008, it has been actively developing the mine of Los Filos, in the municipality of Eduardo Neri, which could become Latin America’s largest gold mine.

Los Filos is in Guerrero’s “Gold Belt” that runs from Mezcala to Argelia. The open-cast mine at Los Filos is midway between Mezcala and El Carrizalillo, some 50 km from the state capital Chilpancingo. The mining project will employ 800 workers and double the population of El Carrizalillo. The rocks here contain between 0.5 and 0.8 grams of gold per ton of ore. Los Filos is expected to yield 60 million metric tons of gold ore over the next 20 years, as well as some ancillary silver, lead and zinc. The mining operation will require investments of $1 billion over the mine’s anticipated 20-30 year lifetime.

The Los Filos project is actively opposed by several environmental groups, including The Mexican Network of People Affected by Mining (La Red Mexicana de Afectados por la Minería, REMA), a network of communities, movements, organization, groups and individuals “affected by, and concerned about, the socio-economic impacts of mining in Mexico”.

REMA has joined the campaign to force Canadian mining firm Goldcorp to halt work at Los Filos. REMA supports the recently created  Mesoamerican Movement Against the Extractive Mining Model, which claims that the existing extractive mining model has proven to be “highly predatory”, and has “significantly increased extraction, causing destruction of territory, seriously affecting natural resources, and irreversibly damaging the health of Mexican citizens”. It is especially concerned that hundreds of tons of cyanide have already been used in Mexico to process gold ore, contaminating water reserves.

REMA cites Goldcorp’s “Los Filos” mining project in Guerrero as a point of particular concern and an example of what is happening throughout the country. REMA claims that there is inadequate regulation and environmental monitoring and that the project is “causing division of communities, disease and death from the chemicals used and environmental damage through drainage of acids and polluting dusts”.

Another Goldcorp mining proposal, at Alto Lucero in the state of Veracruz, also met with substantial opposition from local residents and environmental groups. For more information about the amounts of cyanide believed to be used in mines throughout Latin America, including Goldcorp projects, see:

Will Los Filos turn out to be a mega-mine or a mega-disaster? Only time will tell.
