IAMGOLD Corporation reported preliminary operating results for the fourth quarter and full year of 2017. For the quarter, the company reported attributable gold production for the fourth quarter 2017 was 228,000 ounces.

For the year, the company reported full year attributable production of 882,000 ounces was at the top end of guidance of 845,000 to 885,000 ounces, with production from owner-operator sites exceeding guidance and Essakane achieving record production.

For the year 2018, the company expects production to range between 850,000 and 900,000 ounces. The company expects production to be at a similar level to 2017 due to higher grades, partially offset by lower throughput. The proportion of hard rock in Rosebel's mill feed is expected to increase to approximately 60% from 45% in 2017. The company expects 2018 production to be lighter in the first half of the year, reflecting lower production at Rosebel as a result of mine sequencing.

For the year 2018, the company expects total capital expenditure guidance of $365 million.
