OceanaGold announces encouraging drill results at Macraes Goldfield

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

MELBOURNE, July 7, 2015 /CNW/ - OceanaGold Corporation (TSX/ASX/NZX: OGC) ("OceanaGold") is pleased to announce encouraging drill results from exploration within the Macraes Goldfield in New Zealand. During the first quarter of 2015, the Company commenced a drill program at Macraes focused on drilling a number of surface targets along the 30-kilometre strike of the Hyde-Macraes shear zone that hosts the gold mineralisation. Drilling also continued at the existing Frasers Underground Mine.

Key Highlights

• Discovered new zone of gold mineralization north of the existing Coronation Pit with significant intersections that include 11 metres @ 2.31 g/t, 22 metres @ 2.20 g/t, 8 metres @ 4.58 g/t and 18 metres @ 1.86 g/t.
• Confirmed a zone of stockwork mineralisation at Innes Mills with significant intersections that include 16 metres @ 2.40 g/t, 19 metres @ 1.21 g/t, 19 metres @ 1.21 g/t and 8 metres @ 2.23 g/t.
• Identified significant mineralization at the Frasers Underground Mine with intersections that include 17.5 metres (true width) @ 2.74 g/t, 22 metres (true width) @ 2.65 g/t, 9 metres (true width) @ 5.18 g/t and 12 metres (true width) @ 2.24 g/t.

Mick Wilkes, Managing Director and CEO commented, "Changes to macro-economic conditions such as lower fuel costs and a weaker New Zealand dollar have resulted in significant benefits to our New Zealand operations. On the backdrop of these strong tailwinds, we initiated a comprehensive and targeted brownfields exploration program at the Macraes Goldfield earlier this year, focusing on areas peripheral to existing and previous open pits." He added, "I am pleased to report that initial drilling has produced significant results that demonstrate the potential for increased reserves at the Macraes operations. We expect these programs to continue throughout 2015 and currently have five drill rigs operating on open pit and underground targets."

The initial exploration program has focused on four specific areas as indicated by Figure 1. Drilling has taken place to the north and immediate south of the existing Coronation open pit, at the previously mined Innes Mills pit and in the existing underground operations at Frasers.

Coronation

Under the current exploration program, the Company has drilled 70 holes for 6,857 metres at Coronation. Drilling has focused one kilometre to the north and immediately to the south of the existing Coronation open pit (Figure 2). Results received to date at Coronation North have outlined an approximate 600 metre by 150 metre wide ore shoot on a northwest trend to the north of the existing pit that is currently open at both ends (Figures 2 – 4). Significant results from this drilling are listed in Table 1 while additional assays are pending.

Frasers Underground

Over the past several years, the Company has successfully increased mineral reserves at the Frasers Underground through drilling down dip of existing workings. In the current exploration program, 34 holes for 5,633 metres have taken place down dip of planned mining development at Panel 1 and Panel 2 (Figure 5). Initial results from drilling have defined significant mineralisation as indicated by Table 2 (see Figure 6 and 7). Additional assays are pending.

Mick Wilkes added, "As we await additional assay results, we will continue to drill our primary targets at the Macraes Goldfield to further identify mineral resources that have the potential to increase the mine life at Macraes. The new potential at our existing operations in New Zealand will further complement our acquisition of the high quality Waihi Gold Mine and collectively forms a strong standalone business unit that with Didipio, generates significant free cash flows."
