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

MELBOURNE, Oct. 22, 2018 /CNW/ - OceanaGold Corporation (TSX: OGC / ASX: OGC) (the "Company") is pleased to provide an update on its extensive exploration program at Macraes in New Zealand where since November 2017, the Company has drilled 287 holes for 33,249 metres mainly at Golden Point, Coronation North, Coronation, Deepdell North and Frasers Underground ("FRUG") targets – see Figure 1.

Mick Wilkes, President and CEO of OceanaGold said, "The Macraes Gold Mine has successfully operated since 1990 and today is one of the most efficient operations in the world. It has generated meaningful cash flows and consistently delivered mine life extensions. It is an operation that had an initial 7-year mine life in 1990, a 2-year mine life in 2007, a 4-year mine life in 2013 and today after 28 years of operations, has a current mine life to 2021. It is an operation that has delivered significant benefits to the local economies in Otago and clearly demonstrating world-class environmental practices."

He added, "Over the course of the past year, we have invested $5 million drilling several targets on the 32-kilometre strike length of the Hyde-Macraes Shear Zone. The latest drill results have exceeded our expectations and we seek to leverage these results into tangible resource growth."

"More recently, we have been working on a new mine plan focused on the economic extraction of ore currently not in Reserves but located within existing deposits. This work, coupled with the exploration success indicate the potential for a profitable mine life extension beyond 2021 at today's gold price. Additionally, we continue to investigate the technical and economic viability of the Round Hill Project, which represents a potential redevelopment of Macraes that could add an incremental 10 years of mine life to the operation."

"Drilling at Golden Point, which is an exploration target within the Round Hill Project, has yielded significant drill intercepts close to surface and at depth. Based on these results, we are following up with further drilling and investigating a potential underground mine."

At Golden Point, 19 holes for 4,634 metres have been drilled since November 2017, targeting the down-plunge continuation of the Golden Point mineralisation. Significant mineralisation was intercepted in 14 holes (Table 1, Figure 2 and Figure 3) extending the mineralised zone east. Drill results continue to highlight a potential pit lay-back plus now a potential underground with recent gold intercepts returning 9.0 metres @ 4.63 g/t Au, 9.0 metres @ 3.85 g/t Au, 11.8 metres @ 2.35 g/t Au and 6.6 metres @ 3.97 g/t Au.

Mineralisation closer to surface and proximal to the pit wall delivered significant intercepts that included 15.0 metres @ 4.28 g/t Au and 5.0 metres @ 5.22 g/t Au. Mineralisation remains open down plunge of both Golden Point and Round Hill deposits. These results along with previous drill results support a potential pit re-optimisation and will be incorporated into an updated resource estimate. The updated resource and pit optimisation will guide the advancement of the Round Hill Project.

Drilling at Coronation North, Coronation and Deepdell consisted of targeted infill programs in support of an updated 2019 Life of Mine Plan ("LOMP"). At Coronation North (Table 1 and Figure 4), a discovery made in late 2015, 86 holes for 8,226 metres were drilled predominantly within the current pit design. The drill results were in-line with expectations and resulted in a conversion of an additional 14,000 ounces to Measured and Indicated Resource categories.

At Deepdell North (Table 1 and Figure 5), 90 holes for 9,289 metres were drilled as part of an infill drill program to confirm continuity of the lower zone of mineralisation and better delineation of the main ore shoot. The resource estimate update is under review.

At Coronation (Table 1 and Figure 6), 72 holes for 8,779 metres were drilled targeting a proposed Stage 5 cut-back of the existing pit to increase the understanding of the ore shoots as well as providing flexibility around the LOMP. Drill results demonstrate additional resources and the inclusion of a Coronation Stage 5 would extend the mine life at Macraes by approximately five months.

At the Frasers Underground (Table 1 and Figure 7), 20 holes for 2,320 metres were drilled as part of a resource definition program to support the LOMP.

Looking ahead, drilling will focus on completion of the Coronation North drill-program in the fourth quarter and further step out drilling at Golden Point and Round Hill, specifically targeting down-dip extensions to mineralisation intersected earlier this year.

Mick Wilkes added, "This year at Macraes, production has been significantly higher than in previous years due to the discovery of higher grade ore from Coronation North. The operation has contributed materially to the Company's strong 2018 free cash flow generation while next year the operation is expected to continue contributing materially to the Company, both in terms of production and free cash flow generation. The Macraes operation is highly levered to the gold price and the resource is vast. With some of the best technical expertise in the gold mining industry, I remain confident that the Macraes operation will be an important part of the OceanaGold business for many years to come."
