Tanzania's largest gold miner reported a 17% jump in third-quarter core profit, and said it anticipates full-year costs at the lower end of it target range of $1,100-$1,175 per ounce sold.
The controversial duties, imposed earlier this month, will be eliminated once ongoing negotiations on a free trade agreement (FTA) between the two nations is finalized.
The giant copper miner is also planning to sell about $8 billion of bonds over the next five years to help finance a nearly $30bn investment program aimed to revamp its aging mines.
