The conflict minerals movement is gaining traction. The movement is a pragmatic effort to address one of the principal drivers of atrocities and conflict throughout Congo’s tortured history: the scramble for control of Congo's vast mineral resources. In eastern Congo today, these mineral resources are financing multiple armed groups, many of whom use mass rape as a deliberate strategy to intimidate and control local populations. Armed groups and military units earn hundreds of millions of dollars per year by trading four main minerals: the ores that produce tin, tantalum, tungsten, and gold. This money enables the militias to self-finance their campaign of brutal violence against civilians, with some of the worst abuses occurring in mining areas.
