South African miner Sibanye-Stillwater, which has made an offer for AngloGold Ashanti’s Mponeng, the world’s deepest gold mine, said on Thursday it doubted its bid would succeed. AngloGold is selling the asset, its last operation in South Africa, as it pursues higher returns elsewhere. Precious metals miner Sibanye-Stillwater has expressed interest, as has Harmony Gold.
