The first South African project to bring illegal miners into the formal fold has been plagued by violence in diamond capital Kimberley, dealing a major blow to national efforts to stem a booming illicit trade. The project was launched 18 months ago in Kimberley, the site of a nineteenth-century diamond rush that lured fortune-seekers from the world over. Mine owners granted more than 800 unlicensed, or informal, small-scale miners the right to legally mine around 1 500 acres of diamond-rich waste fields.
