OceanaGold Intersects Additional High-Grade Gold and Silver Mineralisation at WKP

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

MELBOURNE, Feb. 12, 2019 /CNW/ - OceanaGold Corp. (TSX: OGC / ASX: OGC) (the "Company") is pleased to announce the continuing intersection of high-grade gold mineralisation during resource definition drilling along the East Graben vein at the Company's WKP prospect in New Zealand. These drill results support the high-grade results reported in 2018 and will enable geological modelling and resource estimation to define a maiden resource later in the year.

Significant Intercepts (true widths) 

• 9.0m @ 21.15 g/t Au, 24.4 g/t Ag               East Graben main vein
• 10.1m @ 19.22 g/t Au, 20.0g/t Ag              East Graben main vein
• 2.4m @ 39.6 g/t Au, 101.8 g/t Ag               East Graben main vein
• 4.0m @ 15.11 g/t Au, 21.1 g/t Ag               East Graben main vein
• 10.0m @ 43.37 g/t Au, 59.5 g/t Ag             East Graben footwall vein
• 6.2m @ 12.33 g/t Au, 20.8 g/t Ag               East Graben footwall vein
• 4.2m @ 16.76 g/t Au, 25.4 g/t Ag               East Graben footwall vein

Mick Wilkes, President & CEO of OceanaGold said, "We are very excited about the potential at WKP. Drilling continues to yield high-grade intercepts across multiple veins with each hole increasing our confidence of a potential resource and possible new major discovery located close to the Waihi operation. Discoveries such as these have the potential to further create employment opportunities while delivering socio-economic benefits to local communities and nationally."

"For 2019, we expected to invest between $8 million and $10 million to drill the WKP target. Our current focus continues to be the East Graben vein which has not yet been fully delineated but currently extends 1,000 metres along strike with an average width of 5 metres and an average grade of approximately 15 grams per tonne. Two other high-grade veins have been identified in the footwall and hangingwall of the main East Graben vein. We also plan to further drill the T-Stream and Western veins this year with a goal of expanding the size of these veins."

The Company commenced exploration of the WKP prospect in August 2017 and to date has drilled 15,747 metres in 29 holes. Since the September 2018 exploration update 5,361 metres have been drilled at WKP focussing on resource definition drilling of the East Graben Vein; one of three major low sulphidation epithermal gold-silver veins identified to date within the WKP prospect area (Figure 1). In addition to these known veins, the Company has intercepted several high-grade veins in the hangingwall and footwall of the East Graben Vein (Table 1). 

The resource definition drilling completed since the September 2018 exploration update has continued to successfully intersect high-grade mineralisation, increasing the confidence in continuity of mineralisation within the East Graben Vein and associated hanging and footwall veins. The drilling has returned best true width intercepts of 10.1m @ 19.2 g/t gold on the East Graben Vein and 10.0m @ 43.4 g/t gold on a footwall vein (Figure 2, Table 1). This high-grade mineralisation is open along strike in both directions over one kilometre with 200 metres of vertical extent which is open for a further 100 – 200 metres up-dip (Figure 2).

In 2019, the Company expects to complete a further 14,500 metres of resource definition drilling and further drill other major veins on the prospect.
