OceanaGold Receives Permits for the Martha Underground and Mine Life Extension at Waihi

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

MELBOURNE, Feb. 5, 2019 /CNW/ - OceanaGold Corporation (TSX: OGC | ASX: OGC) (the "Company") is pleased to announce that the statutory appeal period related to the Martha Underground Project ("Martha Underground" or the "Project") permitting process has concluded with no appeals filed. As a result, the Project has received its resource consents (permits) to commence operations.

Mick Wilkes, President and CEO said, "Receipt of the permits at the Martha Underground represents a tremendous outcome that will benefit the Company, its shareholders, the town of Waihi and New Zealand. The Waihi operation has had a long, rich history of operating to the highest of environmental and social standards globally while contributing significant socio-economic benefits to Waihi and the country. We are excited to be granted the consents and for the opportunity to continue over 140 years of gold mining history at Waihi."

The Company has started preparing management plans and detailed mine designs to allow mining operations to begin, which will include stope and infrastructure development. The Company expects that at full underground mining rate at Martha, the Waihi operation production would return to more recent historic levels. 

During the ramp-up phase, the Company will continue to drill the Martha Underground targets utilising four diamond rigs from the two underground drill drives located beneath the Martha Open Pit in order to further discover and add resources. Based on studies and exploration to-date, the Company has an exploration target of between five and eight million tonnes grading four to six grams per tonne within the Martha Underground¹. As at August 9, 2018, the Martha Underground hosted a Measured & Indicated ("M&I") Resource of 140,000 ounces of gold and an Inferred Resource of approximately 339,000 ounces of gold, which was based on only one-third of the planned drilling program. Since this date, the Company has continued to drill from underground and has budgeted a further 42,000 metres in 2019 to further test the exploration target.

Mr. Wilkes added, "OceanaGold has been proudly operating in New Zealand since 1990 and the Waihi mine has been in operation in its current form since 1988. We have a strong, dedicated and values-driven workforce that are proud Kiwis making a significant positive impact in their respective communities. New Zealand is a template for responsible hard rock mining, clearly demonstrated by the success we've had at Macraes, Waihi and Reefton gold mines."

¹ Insufficient exploration work has been conducted to date to define a mineral resource of this magnitude and it is uncertain if further exploration will result in the delineation of additional mineral resources. The exploration target is conceptual in nature and is based on the assessment of surface and underground drilling data collected by the Company as well as historical and archived geological and mining data from over a century of mining activity at Waihi. If ongoing exploration and consenting is successful, this could extend underground mining at Waihi.
