The production target and forecast financial information discussed in this slide must be read in conjunction with the cautionary statement on page 3 of the Blackwater Preliminary Economic Assessment dated October 21, 2014 (“PEA”) explaining that there is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target and forecast financial information will be realised. OceanaGold confirms that all material assumptions underpinning the production target and forecast financial information in the Blackwater PEA continue to apply and have not materially changed. 2. Post-tax NPV for base case revenue +/- 25% using a discount rate of 5% is in the range of $40m-$223m with a midpoint of $132m. Please refer to Blackwater PEA for range of NPV results.
