Canada-headquartered miner Barrick Gold on Tuesday reported preliminary second-quarter production of 948 000 oz of gold and 43 000 t of copper and reaffirmed its full-year guidance.

The second-quarter gold output increased by a marginal 0.85% quarter-on-quarter, helped by increased production at Turquoise Ridge, in the US, and the continued ramp-up of the Porgera mine, in Papua New Guinea, as well as significant increases at its African mines.
