ABG ups gold reserve estimate

London-listed African Barrick Gold has increased its gold reserve estimates by 900,000 ounces at the Bulyanhulu Upper East Project in Tanzania as it continues to expand its mining on the project. ABG will now complete a feasibility study on the area. Production for the project is expected to start at the end of 2014 and produce 1.86m gold ounces over the next 20 years.
