MELBOURNE, June 19, 2018 /CNW/ - OceanaGold Corp. (TSX: OGC) (ASX: OGC) (the "Company") is pleased to announce that is has increased its 2018 consolidated gold production guidance on the back of strong operating performance and improvements to the mine plan at the Didipio Operation. As a result, the Company's 2018 gold production guidance range has been revised upward and now sits at 500,000 to 540,000 ounces.

Mick Wilkes, President and CEO said, "We have had a strong operating and financial performance in the first half of this year with our operations achieving better than expected results. With the improvement to the mine plan, Didipio continues to outperform and present opportunities for further optimisation while ramp-up of the underground is progressing nicely. Operating performance at Haile has been strong with recent solid plant performance while mining activities are gradually improving. In New Zealand, after a slow start Waihi is back on track while Macraes is slightly exceeding expectations with improved plant performance and a steady feed of higher grade ore from Coronation North."

"With the increase to our production guidance and strong financial performance, we fully expect to maintain our standing as one of the most profitable gold companies globally."
