The Globe and Mail reports in its Thursday edition that Barrick Gold on Wednesday estimated its gold production in 2016 fell 9.8 per cent to 5.52 million ounces. A Reuters dispatch to The Globe says that the world's largest producer of bullion also estimated 2016 all-in sustaining costs was at or slightly below the low end of its forecast of $740 to $775 an ounce of gold (all figures U.S.). In comparison, Barrick had all-in sustaining costs of $831 an ounce in 2015. Barrick also estimated its cost of sales applicable to gold last year was at the low end of the forecast of $800 to $850 per ounce it gave in October. Barrick estimated its full-year copper production dropped 18.8 per cent to 415 million pounds, with all-in sustaining costs of $2 to $2.20 a pound. These costs were $2.33 a pound in 2015. Barrick closed Wednesday at $23.60 (Canadian), down 24 Canadian cents on the Toronto Stock Exchange.
