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

MELBOURNE, Australia, Jan. 18 /CNW/ - OceanaGold Corporation (ASX: OGC, TSX: OGC, NZX: OGC) (the "Company") is pleased to announce an increase of 259,000 ounces of gold to the mineral reserve inventory at the Macraes mine in Otago, New Zealand, which extends the mine life out to at least 2016.

These reserves are in addition to the Company's December 2009 announcement of an increase of 495,000 ounces of reserves. When combined, this brings the total additional gold reserves at the Macraes mine to 754,000 ounces.

The additional mineral reserves announced today follow a comprehensive geologic interpretation and economic analysis for the "Southern Pit" deposit. The gold price assumption used to calculate reserves was US$800/oz. Further specifics are set out in "Table A" below.

Paul Bibby, CEO commented, "The additional reserves that have been added at the Macraes open pit mine are a further reflection of the potential that exists within the Macraes goldfield to convert resources to reserves. There is a significant resource base at Macraes and over the past few months we have successfully added three years to the mine life through this conversion program, extending the operation out to at least 2016. We expect further positive results from the programs to continue over the coming months."
