/NOT FOR DISSEMINATION OR DISTRIBUTION IN THE UNITED STATES AND NOT FOR DISTRIBUTION TO US NEWSWIRE SERVICES./

MELBOURNE, Australia, Sept. 19, 2018 /CNW/ - OceanaGold Corporation (TSX: OGC / ASX: OGC) (the "Company") provides an update on its Didipio operation in the Philippines and Haile operation in the United States, where over the past weekend severe weather impacted surrounding areas.

Mick Wilkes, President and CEO of OceanaGold said, "The safety and well-being of our employees is paramount and I'm very happy to announce that following major storms in the Philippines and in the Carolinas no injuries were reported. The Company uses stringent processes and operational readiness practices ahead of potential severe weather events to ensure workers are safe, the site is secure and our robust environmental safety controls are in place."

He went on to say, "Our valued workforce at both the Didipio and Haile operations were well prepared and equipped to deal with a worst-case scenario weather event and both operations are designed to withstand hurricanes, tornados or other severe weather. Our community relations teams remained in close contact with local authorities and communities throughout the storm and in the aftermath, we offered our assistance in recovery efforts."

"Operationally, we do not expect any impact to production at either operation as a result of these storms."

Philippines

In the Philippines, the Didipio operation reported no injuries or environmental impacts associated with Super Typhoon Mangkhut, a category five storm that impacted northern Philippines. At Didipio, the centre of the storm travelled north of the operation, however the site received a moderate amount of rainfall. As Didipio is designed for and accustomed to significant rainfall and strong wind events, particularly during the typhoon season, the site was well prepared in advance of the storm. Following a brief stoppage of operational activities, the Didipio operation was safely restarted.

The impact of the storm on the Philippines was significant and as part of their preparations the Company had dispatched a Typhoon Response Team to assist local and regional government authorities in their recovery efforts within the Cagayan Valley to the north of the operation. In the past, Didipio's Typhoon Response Teams have provided support to other similar storms such as Super Typhoon Haiyan (also known as Yolanda) that devastated the Visayas region in Central Philippines in 2013.

United States

In the United States, the Haile operation reported no injuries or environmental impacts associated with Tropical Storm Florence, which significantly impacted coastal areas in North and South Carolina. The centre of the slow-moving storm travelled south of Columbia, South Carolina (Haile located 60 miles north of Columbia). The Haile operation was well prepared for a worst-case scenario storm event and was temporarily suspended on Friday ahead of the weather and for the safety of the workforce who commute to and from site. The process plant was safely and successfully restarted on Sunday while mining resumed on Monday.

Prior to, during and after the storm, the Haile operation worked closely with local communities and maintained open communication lines during the storm to support their needs and well-being. In the aftermath of the storm, the Haile operation offered its support and assistance for any emergency clean-up required.
