OceanaGold Corporation : OceanaGold Didipio Mine Update

25 February 2013

(MELBOURNE) OceanaGold Corporation (ASX: OGC, TSX: OGC, NZX: OGC) (the "Company") wishes to provide an update on its Didipio Mine located in Luzon, Philippines which is currently undergoing commissioning activities.
Ramp up of the process plant continues to track well. To date, approximately 2,500 tonnes of copper- gold concentrate has been delivered to port and in excess of an additional 2,500 tonnes has been produced and is awaiting transport from the minesite.
The Company wishes to advise that it is currently in discussions with various government departments over interpretations of tax exemptions pertaining to OceanaGold's Financial and Technical Assistance Agreement (FTAA). Didipio is the first project to be built and commence operations in the Philippines under the FTAA structure. Due to these clarifications on tax exemptions being sought, some of the trucks used for transporting concentrate are being held by local government agencies and thus transportation of copper-gold concentrate has been temporarily suspended. While these discussions take place, mining and processing operations continue.
