Nearly 1,000 suspected zama-zamas mostly undocumented foreign nationals have been arrested at Sheba Gold Mine in Barberton, Mpumalanga. The raid, part of Operation Vala Umgodi involving SAPS and the SANDF, forced the miners to surface after food supplies ran dry. Police say those arrested face charges under the Immigration Act and for illegal mining. Authorities have vowed to dismantle criminal mining networks in the province.
