The second-quarter earnings and free cash flow of AngloGold Ashanti more than doubled year-on-year, driven by the high gold price and what the New York- and Johannesburg-listed company highlights as continued cost discipline and a 21% increase in gold production. The second-quarter free cash flow of $535-million was 149% up on the corresponding period of last year with the 25% gold production from managed operations supported by strong contributions from Obuasi in Ghana and Geita in Tanzania as well as the addition of the Sukari gold mine in Egypt.
