Maybe this has something to do with Anglo being patient?AngloGold Ashanti (NYSE:AU) says the recent surge in gold bullion prices has not made it easier to sell the mines it has put up for sale. "It's a challenging market in terms of divestment because of speculation on potential assets coming into the market," CEO Kelvin Dushnisky, said during today's earnings conference call. The CEO said AU has received "several bids" for the operations it wants to offload, which include Cerro Vanguardia in Argentina and Mponeng in South Africa.
