OceanaGold announces receipt of its FTAA exploration permit renewal and updated resources and reserves

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

MELBOURNE, March 30, 2016 /CNW/ - OceanaGold Corporation (TSX/ASX/NZX: OGC) (the "Company") is pleased to announce that it has received a five year extension to the exploration period of its Financial or Technical Assistance Agreement in the Philippines ("FTAA exploration permit"). The Company is also pleased to announce the updated Resource and Reserve Statement as at 31 December 2015.

Mick Wilkes, President and CEO said, "We are very pleased to announce that the Mines and Geosciences Bureau in the Philippines has granted the renewal of the Company's FTAA exploration permit. This is a positive outcome for all stakeholders that will allow the Company to expand its exploration program over the broader region around Didipio. We are now reviewing and prioritising targets and expect to provide clarity around the planned exploration programs in the coming weeks."

He added, "As a recent recipient of the highly prestigious 'Most Responsible' mining operation award from President Aquino III, we have demonstrated to our stakeholders that we operate to the most stringent social, environmental and safety standards. As ever, we will continue working with all levels of Government and all stakeholders delivering meaningful benefits to our host communities and to every country in which we operate."

OceanaGold holds significant exploration tenements in the Philippines and the FTAA covers approximately 158 km² located in the provinces of Nueva Vizcaya and Quirino. Over the past few years, previous geochemical sampling has identified several gold and copper soil anomalies in close proximity to the Didipio operation. In the coming weeks, the Company will re-examine and prioritise its drill program for the FTAA bounded area. Figure 1 outlines the area bounded by the Company's FTAA and targets defined from previous geochemical sampling.

Mr. Wilkes said, "We are very pleased to announce a material increase in our resources, which are mainly attributable to the acquisitions completed last year that brought the Haile and Waihi gold mines into our portfolio of high quality assets. The Company already has a significant mineral endowment and through an extensive exploration program, we are seeking to significantly extend that endowment from our highly prospective exploration tenements in New Zealand, the Philippines and United States."

On a consolidated basis, the Company's total Proven and Probable ("P&P") Reserves stand at 5.46 Moz of gold, 4.51 Moz of silver and 0.18 Mt of copper. Gold reserves have increased 80% year-on-year, net of mining depletion, mainly as a result of the additional reserves from the Waihi and Haile gold mines. The P&P Reserves at Didipio were calculated using US$1,300/oz gold and US$3.20/lb copper. At the New Zealand operations, reserves were calculated using US$1,300/oz gold price and NZD/USD FX rate of 0.70, while at Haile, a US$950/oz gold price was used to calculate reserves. See Table 1.

Measured and Indicated ("M&I") Resources (inclusive of reserves) for the Company now stand at a total of 11.6 Moz of gold, 14.8 Moz of silver and 0.22 Mt of copper. Over the past year, the Company increased its consolidated M&I Resources by 3.8 Moz of gold, while increasing the average gold grade to 1.52 g/t from 1.35 g/t. The increase in M&I Resources, net of mining depletion, is due mainly to the addition of the Haile and Waihi gold mines and successful drilling at Macraes.

Total Company Inferred Resources stand at 3.7 Moz of gold, 2.5 Moz of silver and 0.03 Mt of copper.

At Macraes, P&P Reserves at the end of 2015, stood at 1.22 Moz of gold including 0.15 Moz of gold at the Frasers Underground. The P&P Reserves grew modestly by 0.05 Moz of gold net of mine depletion following a successful drilling at Coronation North which added 0.12 Moz of gold and Frasers Underground adding 0.04 Moz. Macraes continues to have a large resource base with total gold resources including 3.59 Moz of M&I Resources in addition to 1.5 Moz of Inferred Resources. The Company will continue to drill Coronation North, Frasers Underground and other high-ranking targets located along the 30-kilometre strike length at Macraes.

In latter part of the fourth quarter 2015 at Waihi, the Company commenced drilling at Correnso and other underground targets such as Daybreak and Empire. As a result of the drilling, the Company successfully increased underground reserves by 0.07 Moz of gold, net of mine depletion and established a maiden reserve of 0.042 Moz on the Daybreak vein. As at the end of 2015, Waihi had P&P Reserves of 0.30 Moz of gold and 0.52 Moz of silver in the underground while the open pit reserves remain unchanged at 0.076 Moz gold and 0.77 Moz of silver. Drilling of Correnso and other underground targets continue to produce promising results with significant intercepts that are consistent with widths and grades currently mined at Correnso. In 2016, the Company will drill approximately 34 kilometres at Waihi and regional targets.

At Didipio in the Philippines, total P&P Reserves stood at 1.55 Moz of gold, 3.22 Moz of silver and 0.18 Mt of copper, a decrease year-on-year as a result of mine depletion. In 2016, the Company will continue to drill near mine targets and, in the second half of the year, will commence infill and extensional drilling of the underground resource.

At the beginning of October 2015, the Company completed the acquisition of Romarco Minerals Inc. which brought the top tier Haile Gold Mine into its portfolio. The current P&P Reserves at Haile stand at 2.02 Moz of gold which is based on a gold price assumption of US$950/oz. In the fourth quarter of 2015, the Company commenced an infill drill program on Horseshoe which has returned significant high-grade intercepts that support the resource model (refer to Company press release issued 29 February 2016). The Company will drill 40 kilometres at Haile and regional targets in 2016 as it seeks to further define the resource at Horseshoe and progress a number of additional targets within the pipeline.

In May 2015, the Company made a strategic equity investment in Gold Standard Ventures ("GSV"), a junior exploration company exploring in the prolific Carlin Trend. As at the end of 2015, the Company owned a 15.2% equity stake in GSV resulting in an attributable total Resource of 0.26 Moz of gold including 0.2 Moz in Inferred Resources. In early February 2016, the Company increased its investment in GSV and now holds 19.9% of all outstanding common shares, following the purchase of an additional 12,565,265 GSV shares

Mr. Wilkes added, "We will continue to unlock organic value in our business. With continued strong cash flows expected from our operations in 2016 and higher production at even lower costs expected in 2017, the Company is well positioned to further increase its resource base organically and through selective external opportunities. With the granting of our exploration permit renewal in the Philippines, we will now expand our exploration program in 2016 to include the significant opportunities that exist for us there."

OceanaGold Corporation is a mid-tier, low-cost, multinational gold producer with assets located in the Philippines, New Zealand and the United States. The Company's assets encompass its flagship operation, the Didipio Gold-Copper Mine located on the island of Luzon in the Philippines. On the north island of New Zealand, the Company operates the high-grade Waihi Gold Mine while on the south island of New Zealand, the Company operates the largest gold mine in the country at the Macraes Goldfield which is made up of a series of open pit mines and the Frasers underground mine. In the United States, the Company is currently constructing the Haile Gold Mine, a top-tier asset located in South Carolina along the Carolina Terrane. The Company expects the Haile Gold Mine to commence commercial production in early 2017.

Notes:
1.	OceanaGold's interest in the Sams Creek Project has reduced from 40% to 20%. The tabulated resource is factored by the percentage ownership.
2.	As at December 31, 2015, OceanaGold held 15.2% of the issued and outstanding shares in Gold Standard Ventures Corp ("GSV"), which owns the Dark Star and Pinion deposits in Nevada, USA. The tabulated resource is based on resource as reported by GSV, and factored by OceanaGold's 15.2% equity ownership in that company. On February 10, 2016, OceanaGold extended its equity ownership in GSV from 15.2% to 19.9% following the purchase of an additional 12,565,265 GSV shares. GSV reports that the Pinion Project also includes 77 Mt @ 3.8 g/t Ag for 9.43 Moz of silver which is classified as Inferred Resource.
