African Barricks Profit More Than Doubles, Cash Costs Rise 2011-10-20 06:32:19.555 GMT By Thomas Biesheuvel Oct. 20 (Bloomberg) -- African Barrick Gold Plc, the largest producer of the metal in Tanzania, said third-quarter profit more than doubled as output increased and gold prices rose, even as mining costs increased. Net income climbed to $102.1 million in the period from $39.9 million a year earlier, the London-based company said today in a statement. Attributable gold output advanced 11 percent to 182,401 ounces. Gold producers profits have been buoyed by record prices for bullion as Europes sovereign-debt woes spur demand for precious metals as a haven. Gold for immediate delivery averaged a record $1,706.38 an ounce in the third quarter, compared with $1,227.73 an ounce a year earlier.
