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

MELBOURNE, Feb. 27, 2019 /CNW/ - OceanaGold Corporation (TSX: OGC) (ASX: OGC) (the "Company") is pleased to announce an update on exploration activities at the Company's Haile Gold Mine ("Haile") in South Carolina, United States. This exploration update follows the update provided to the market on August 16, 2018 ("August 2018 update") and results herein reflect activity completed after this date.

Selection of significant drill results:

• 68.3 metres @ 3.57 g/t Au at Snake expansion
• 24.4 metres @ 8.19 g/t Au at Snake
• 33.4 metres @ 4.33 g/t Au at Ledbetter
• 15.1 metres @ 9.26 g/t Au at Ledbetter
• 24.5 metres @ 3.21 g/t Au at Ledbetter
• 20.1 metres @ 7.23 g/t Au at Red Hill

Mick Wilkes, President and CEO of OceanaGold said, "The Haile exploration program has focused on drilling in and around the footprint of the existing deposits. Drilling continues to demonstrate the opportunity to add further resources in these areas and replenish reserves."

"With the permitting process of the larger open pits and the Horseshoe Underground advancing well, we expect to commence construction upon receipt of these permits. After the Horseshoe Underground has been developed, we also expect to resume drilling deeper targets from underground using a similar approach to that taken at Waihi, particularly the mineralised corridor between Horseshoe and Palomino."

Since the August 2018 update, the Company has drilled 67 drill holes for a combined 12,772 metres using four surface diamond drill rigs. This includes 55 brownfield holes at Haile and 12 holes at the nearby Locust greenfields target. Resource infill and extensional drilling has targeted low-cost reserve growth areas in and around the Ledbetter, Snake, Red Hill, and Haile deposits (Figure 1).

Favourable extensional drill results are expected to add ore-grade mineralisation between pit designs at low strip ratios (Table 1). Infill and delineation drilling continue to support our models including the Ledbetter area (Figures 1 & 2). An 18-hole diamond drill program was completed outside the $1,300/oz reserve pit design and within the resource shell at the Snake West extension and returned positive results. Phase two drilling of 11 holes has recently been completed (Figures 1 & 2) with assay results pending.

Resource drilling is planned in 2019 at Ledbetter, Snake, Red Hill, and Haile in addition to testing other priority targets.
