MELBOURNE, March 31, 2015 /CNW/ - OceanaGold Corporation (TSX/ASX/NZX: OGC) (the "Company") is pleased to announce the updated Resource and Reserve Statement as at 31 December 2014.
- Increase in Proven and Probable reserves at Didipio after depletion.
- Total consolidated Proven and Probable gold reserves of 85.9 Mt @ 1.09 g/t for 3.02 Moz of gold including 3.58 Moz of silver and 0.21 Mt of copper.
- Total consolidated Measured and Indicated resources of 181 Mt @ 1.35 g/t Au for 7.82 Moz of gold including 13.8 Moz of silver and 0.24 Mt of copper.
- Didipio Measured and Indicated resources of 2.02 Moz of gold, 4.32 Moz of silver and 0.24 Mt of copper (57.3 Mt @ 1.10 g/t Au, 2.34 g/t Ag and 0.42% Cu).
- Macraes Goldfield Measured and Indicated resources of 3.58 Moz of gold (101 Mt @ 1.11 g/t Au).
- Frasers Underground mine life extended to the end of 2016 at current rates.
- Reefton Goldfield Measured and Indicated resources of 0.70 Moz of gold (14.4 Mt @ 1.50 g/t Au).
Mick Wilkes, Managing Director and CEO commented, "OceanaGold has a solid resource base from its portfolio of high quality assets. We have seen a year-on-year increase in resources at Didipio driven by the strong results generated from the optimisation study. We continue to add mine life to our Frasers Underground operation, which has been extended by an additional year of production at similar rates to previous years."
On a consolidated basis, the Company's total Proven and Probable ("P&P") reserves stand at 85.9 Mt with 3.02 Moz of gold, 3.58 Moz of silver and 0.21 Mt of copper. This represents a slight decrease from the previous year as a result of mine depletion but partly offset from an increase to Didipio reserves following the Didipio optimisation study. The P&P reserves were calculated using US$1,250/oz gold and US$3.20/lb copper.
At Didipio in the Philippines, P&P reserves were slightly higher due to the at depth expansion of the underground mine design. The increase was partly offset by a reduction of reserves from the open pit following the changes made to the mine design in the optimisation study and from mine depletion. Overall, the Didipio reserves increased to 47.6 Mt from 45.6 Mt while the gold reserve increased to 1.70 Moz from 1.59 Moz with a slight increase in reserve grade to 1.11 g/t. Copper reserve remained steady year-on-year after depletion.
In 2014, the Company completed the geophysical survey of the Didipio area to identify new drill targets. In 2015, the Company continued drilling within the mine area to find additional sources of mill feed with some promising early results.
In New Zealand, P&P reserves stand at 38.4 Mt @ 1.07 g/t Au for 1.32 Moz of gold, a reduction from the previous year due mainly to mine depletion. At the Frasers Underground, additional reserves were defined resulting in an extension to the mine life out to the end of 2016, one year later than previously stated. In each of the past several years, the Company has successfully defined additional reserves at the Frasers Underground, resulting in additional mine life at the operation.
Measured and Indicated ("M&I") resources (inclusive of reserves) for the Company now stand at a total of 181 Mt @ 1.35 g/t Au for 7.82 Moz of gold including 13.8 Moz of silver and 0.24 Mt of copper. The M&I gold resource has decreased 0.52 Moz from the previous year as a result of mine depletion and a reduction in the M&I gold resource at Macraes due to the pit wall failure at the Frasers pit. The decrease was partly offset by additional Didipio M&I gold resources following the optimisation study and increased stockpiles and from an increase to the Round Hill M&I resource.
The M&I silver resource increased by 4.32 Moz from the previous year due to the estimation of the silver content in the Didipio ore body. The M&I copper resource decreased slightly as a result of mine depletion.
Total Company Inferred resources stand at 104 Mt @ 1.2 g/t Au for 4.1 Moz of gold including 2.5 Moz of silver and 0.04 Mt of copper.
OceanaGold Managing Director and CEO, Mick Wilkes stated "In the Philippines, we are preparing our Paco tenements for a geophysical survey and anticipate drilling there later this year. We will continue to drill the Didipio near mine area and follow-up on the recent drilling. Once we have transitioned to the underground at Didipio, we will carry out infill drilling to convert inferred resources and drill the ore body at depth, which we believe is open."
"In New Zealand, the Company will continue infill drilling at the Frasers Underground mine to increase reserves. With the weaker New Zealand dollar and lower fuel costs, the optionality at Macraes has significantly improved. As a result, the Company will undertake a surface drilling program targeting low-strip mineralisation. Success from this drilling program along with continued improvement in economic conditions may result in a mine life at Macraes beyond 2017 in the current mine configuration."
Mr. Wilkes added, "The Company will also continue to pursue external high quality, low-cost reserves and resources that would further complement our business."

Where the mineral reserve and mineral resource estimates of the Company's Reefton, Macraes and Didipio operations set out in this media release differ from those set out in the Technical Report for the relevant property, such differences arise from updates to such mineral reserve and mineral resource estimates as a result of either depletion through production, addition due to exploration activities or revised economic assumptions. The latest updates of mineral reserves for each of the Company's New Zealand projects were prepared by, or under the supervision of, K. Madambi, while the mineral reserves for Didipio were prepared under the supervision of M. Holmes. The updates of mineral resources for the Didipio project were prepared by, or under the supervision of, J. G. Moore, while the updates of mineral resources for Macraes and Reefton were updated by S. Doyle. M. Holmes, K. Madambi, J. G. Moore and S. Doyle are Members and Chartered professionals with the Australasian Institute of Mining and Metallurgy and each is a "qualified person" for the purposes of NI 43-101. S.

Messrs Moore, Madambi, Doyle, Holmes and Ristorcelli consent to inclusion in this media release of the matters based on their information in the form and context in which it appears.
Cautionary Note Regarding Mineral Resources and Mineral Reserves
The Company's disclosure of Mineral Reserve and Mineral Resource information is governed by NI 43-101 under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as may be amended from time to time by the CIM ("CIM Standards"). The disclosure of Mineral Reserve and Mineral Resource information for properties held by the Company is based on the reporting requirements of the 2012 JORC Code. CIM definitions of the terms "Mineral Reserve", "Proven Mineral Reserve", "Probable Mineral Reserve", "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource", are substantially similar to the JORC Code corresponding definitions of the terms "ore reserve", "proved ore reserve", "probable ore reserve", "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource", respectively. Estimates of Mineral Resources and Mineral Reserves prepared in accordance with the 2012 JORC Code would not be materially different if prepared in accordance with the CIM definitions applicable under NI 43-101.
There can be no assurance that those portions of such Mineral Resources that are not Mineral Reserves will ultimately be converted into Mineral Reserves. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All Mineral Reserves are within the Mineral Resource.
