AngloGold Ashanti’s last South African mine is luring potential buyers as the rally in gold boosts profitability. That interest doesn’t mean CEO Kelvin Dushnisky will achieve his target price. AngloGold wants about $500-million for Mponeng and a number of smaller South African assets, according to people familiar with the matter, who asked not to be identified as the issue is private. Harmony Gold Mining and Sibanye-Stillwater have submitted formal proposals, the people said. The discussions are at an early stage and it’s uncertain that they’ll lead to a deal, they said.
