The M4 movement unites groups and organisations in Panama, México, El Salvador, Honduras, Guatemala, United States and Canada.
A recent statement by the movement condemns Goldcorp’s Marlin mine in Guatemala. Goldcorp is a Canadian company with British investment. Among Goldcorp’s major investors are British-based AXA Investment Managers UK Ltd., Blackrock Commodities Income Trust plc and City Natural High Yield Trust plc. In September 2011, Goldcorp was eliminated from the Dow Jones Sustainability Index because of environmental contamination at the Marlin Mine.
