MELBOURNE, Dec. 12, 2016 /CNW/ - OceanaGold Corp. (TSX/ASX/NZX: OGC) (the "Company") is pleased to announce its full year 2017 production and cost guidance which reflects an approximate 35% increase in gold production and 15% decrease in All-In Sustaining Costs ("AISC") from that of 2016.

The increase in production year-on-year is a result of incremental production from the Haile Gold Mine which is nearing completion of construction and the commencement of wet commissioning. In addition to the increase in gold production guidance, the Company is pleased to report decreased AISC guidance which reflects lower costs expected from Didipio and the inclusion of high margin ounces from Haile.

Mick Wilkes, President and CEO said, "Looking to the year ahead, we are well positioned to generate significant free cash flow even in a lower gold price environment. Our strategy to create a high margin business from our portfolio of high-quality assets has been a successful one thus far. As we near the completion of construction at Haile and anticipate the commencement of milling before the end of this year, OceanaGold is poised to continue delivering on its commitments and further solidify ourselves as the gold mining company of choice."
