Unrest among South Africa's platinum miners is spreading, after strikes at one troubled facility last week erupted into violence. About 500 workers at the nearby Royal Bafokeng platinum mine downed tools on Wednesday and blocked fellow miners from going to work. Anglo American Platinum, which is 80 per cent-owned by London-listed Anglo American, has also received a list of demands from a group of workers in South Africa, but the company insisted they were not threatening strike action. Managers from the Lonmin firm met workers' representatives on Tuesday night for the first time since 34 Marikana mine strikers were shot dead by police. Ten other people, including two police officers, died in violence earlier last week. Three thousand striking rock drillers are demanding that their wages be trebled from 4,000 rand (HK$3,750) a month to 12,500 rand a month, and want the release of the 259 people arrested after last week's police action. Anglican Bishop Johannes Seoka, who chaired the talks on Tuesday, said: "All we ask management is to please allow workers to give them their demands, to listen to them and to engage with them." The Lonmin workers' demands have been echoed by rock drillers at Royal Bafokeng who halted work at the nearby Rasimone platinum mine.
