JSE- and NYSE-listed Gold Fields has revised its group-wide full-year production guidance downward, from between 2.33-million and 2.43-million ounces, to between 2.20-million and 2.30-million ounces, owing to a production revision at its Salares Norte project, in Chile, where production is uncertain owing to winter events. The production guidance for Salares Norte has been revised down from the previously indicated gold-equivalent ounces range of 220 000 oz to 240 000 oz, to 90 000 oz to 180 000 oz.
