Acacia, which operates three mines in Tanzania, said it would produce 750,000-780,000 ounces of gold in the year.
The company said its earnings before interest, tax, depreciation and amortisation for the six months to June 30 rose 91 percent to $184.9 million, helped by lower costs and higher gold sales.
