Two decades ago, AngloGold Ashanti (JSE: ANG ) combined its assets in South Africa and became the world's largest gold producer. However, the miner may now have to abandon its home in order to rival competitors that have long since eclipsed the company. According to a Bloomberg report, many analysts are speculating that in order for AngloGold to boost its value and rival companies such as Newmont Mining (NYSE: NEM ) and Barrick Gold (TSX: ABX ,NYSE:ABX), which not only outproduce the miner but have also recently formed mega companies, AngloGold may need to leave the African country. "Their best bet is to get out of South Africa and leave Mponeng behind," said Rene Hochreiter, analyst at Noah Capital Markets. Adding, "[the] costs never come down in South African gold."
