Boasting that the company has hit the upper end of previous production guidance for producing between 1.4 million and 1.5 million ounces of gold at a cost of less than 900,000 South African Rand per kilogram (that’s $48,687 per kilo, or about $1,391 per ounce), and noting that gold prices have proven higher than previously predicted, Harmony issued new guidance for this fiscal year. Earnings per share are now expected to flip from a loss last year to a profit this year.
