OceanaGold posts strong half year production and exploration result

/NOT FOR DISSEMINATION OR DISTRIBUTION IN THE UNITED STATES OR TO US PERSONS AND NOT FOR DISTRIBUTION TO US NEWSWIRE SERVICE/

MELBOURNE, Australia, July 29 /CNW/ - OceanaGold Corporation (ASX: OGC, TSX: OGC, NZX: OGC) (the "Company") increased Second Quarter gold production to 67,541 ounces, bringing total Half Year production to 132,832 ounces.

In its Second Quarter and Half Year 2010 Results released today, the Company announced a 226% increase to its quarter on quarter cash operating margin to US$627 per ounce. This significant increase is due to closing out of the gold hedgebook in March 2010 resulting in the Company now selling 100% of its gold production into the spot market.

Other highlights of the Second Quarter and Half Year Results include:

    
    -   Sold 67,347 ounces of gold during the quarter, an increase of 3.5% on
        First Quarter 2010, bringing the half year gold sales total to
        132,388 ounces.

    -   Posted EBITDA (earnings before interest, taxes, depreciation and
        amortisation and excluding unrealised gains/losses on undesignated
        hedges) of $39.2 million for the Second Quarter.

    -   Achieved significant improvement on process recoveries to 84% across
        the New Zealand operations compared with 80.4% for the same period
        last year.

    -   Announced down-dip extensions to gold mineralisation at the General
        Gordon, Empress and Souvenir open pits at the Reefton mine
        (New Zealand) in April.

    -   Announced the discovery from a surface drilling program down-dip from
        Panel 2 at the Frasers underground mine (New Zealand) in May.

    -   Continued to evaluate various strategic and funding options for the
        Company's Didipio Gold and Copper project in the Philippines, with
        good progress made during the quarter. Mine design optimisation
        studies are nearing the final stages of completion.
    

OceanaGold ranks behind Newcrest and Lihir as the third largest fully unhedged Australasian-based gold producer. The Company expects to produce 270,000 - 290,000 ounces of gold in FY2010.

During the quarter, OceanaGold's exploration program continued to deliver promising results at both the Reefton and Macraes goldfields on the South Island of New Zealand. Drill results from Reefton announced in April outlined the continuation of mineralization below the current planned pit floors leading to an expectation that the pit shells are likely to be expanded. A follow-up drill program commenced in April. At the Frasers underground mine, a new discovery of mineralization down-dip from Panel 2 was announced in May. This was followed up with results from a second program earlier this month that demonstrated good continuity of mineralization between Panel 2 and the new discovery.

OceanaGold CEO, Paul Bibby, said the Company's Second Quarter and Half Year Results demonstrated a solid outcome with the expectation of further production increases in the second half of the year.

Mr. Bibby commented, "This was the first quarter in the Company's history where OceanaGold has been hedge free and 100% exposed to the spot market. This has significantly increased our ability to strengthen the balance sheet and has provided the flexibility to direct investment back into the business as demonstrated by the recent announcement to increase the exploration budget at Reefton."

"With forecast increased gold production in Quarters Three and Four 2010, OceanaGold is on track to further strengthen the business and unlock value within the Company."

OVERVIEW

Results from Operations

OceanaGold recorded quarterly gold sales for Q2 2010 of 67,347 ounces at cash costs of $564 per ounce. Sales for the half year totaled 132,388 ounces at an average cash cost of $557 per ounce.

As expected, sales during the quarter exceeded the previous period and were up 3.5% by volume. An extreme rainfall event at the Macraes goldfield in May did have a negative affect when 50% of the average annual rainfall was recorded over a 2 1/2 day period. This resulted in equipment utilizations at both the Macraes open cut and Frasers underground being well below plan in late May and the start of June and consequently a higher percentage of lower grade stockpiles were processed through the processing plant versus plan. Rock movements returned to normalized levels in June as weather conditions improved.

Cash costs for the quarter of $564/oz were slightly higher predominantly due to an increase in the diesel price and equipment maintenance costs.

It is expected that H2 2010 gold production will exceed H1 2010 and should favorably impact the unit cash costs reported during the second half of the year. Production guidance of 270,000 - 290,000 ounces of gold at cash costs of US$455 - $495 per ounce is maintained.

Cash operating margins have increased substantially with the removal of the hedgebook in March 2010. Margins have increased to $627 per ounce compared to $192 per ounce in Q1. Following the close out of the hedgebook, the gold price in New Zealand Dollars has traded higher throughout the quarter as both the US$ gold price and the exchange rate were favorable.

EBITDA (earnings before interest, taxes, depreciation and amortization and excluding unrealized gains/losses on undesignated hedges) was up sharply when compared to Q1 to $39.2 million. Again, this was on account of 100% of production being sold into the spot market.

Cash flow from operating activities was a net outflow of $21.2 million and included a $56.7 payment in early April for settlement of the remaining outstanding hedge contracts.

Didipio Gold - Copper Project

The Didipio Gold and Copper project in Luzon province, Philippines remains under care and maintenance with a reduced workforce at the project site.

The Company is currently evaluating various strategic and funding options for the project. This is currently a key priority for the management team with good progress being made during the quarter.

OceanaGold continues to maintain a robust community relations and environmental program at the project site during this period. Local community medical care programs and infrastructure upgrades were two key areas of focus during the quarter.

PRODUCTION

Gold production for the second quarter of 2010 was 67,541 ounces, an increase on Q1 as expected. Total production for the half year was 132,832 ounces.

The total combined operating cash costs for the quarter were $564/oz which was slightly higher than the previous quarter and reflects some slight increases to the price of diesel and costs associated with fleet maintenance and contract hires.

OPERATIONS

Macraes Goldfield (New Zealand)

The Macraes operations (open-pit and underground) incurred one lost time injury (LTI) during the quarter compared to one during the same period last year. During the quarter, the Positive Attitude Safety System (PASS) was fully implemented and this new system has been positively received across the workforce.

Production from the Macraes Goldfield for the quarter was 41,504 gold ounces, 6% lower than the previous quarter. The lower production was largely the result of the impact of a heavy rainfall event during the last week of May. This resulted in some flooding within the lower benches of the open pit and equipment utilizations being down on plan. Although weather delays are a normal part of operations in New Zealand, this significant event resulted in the open-pit mining at Macraes being out of action four days longer than the allowance in the plan. Similarly, the underground operations ceased for more than a week while the excess water was removed and ground conditions checked. While operations returned to normal in June, the unplanned down-time at both operations resulted in mining rates being lower than plan and therefore more lower grade stockpiles were utilized through the processing plant.

At the Frasers underground mine, mining took place primarily in the 2D and 2F panels. Total ore mined for the quarter was lower than plan at 212,000 tonnes due mainly to the heavy rainfall event in late May. Underground operations are now operating in-line with plan. Additionally, as at July 1st, the Company transitioned to owner-mining taking over from Byrnecut Mining who had been the contractor since the underground development commenced in 2006. A seamless transition was achieved and the Company expects to extract additional cost savings and efficiencies.

Mill feed through the processing plant was 1.34 million tonnes compared to 1.29 million tonnes in the previous quarter. An improvement in mill throughput resulted from improved ore fragmentation through tighter blast patterns in the open pit reducing the residence time for ore in the mills.

Process plant recoveries at Macraes continued to improve over the previous period at 83.9% for the quarter compared to 81.4% for Q1. Improvements made in late 2009 to the cyclone classification improved both efficiency and capacity and continued to benefit flotation performance. Various improvements have been also been made to the Carbon In Leach (CIL) circuit during the quarter including targeting increased oxidation levels through the autoclave as well as greater controls in the gold elution process.

Reefton Goldfield (New Zealand)

One LTI occurred in the second quarter compared to none during the same period last year.

Material movements were slightly down on the previous quarter as expected due to winter operating conditions. During the winter, more allowance is made for wetter conditions which results in slightly lower equipment utilizations in the open pit compared to summer. Ore delivered to the ROM pad was higher than Q1 however, contributing to another strong quarter at the processing plant.

A positive result at the Reefton process plant was achieved with 401,000 tonnes processed through the mill. This was a 16% increase on the previous quarter's performance. The increase in mill throughput is primarily the result of optimization of the milling circuit and specifically the grinding media which resulted in more efficient grinding and lower re-circulating loads. Flotation recoveries also continued to be strong at 84.3%, in-line with the previous quarter.

Gold production attributable to Reefton was 26,037 ounces and was circa 4,900 ounces higher than Q1 2010. This reflects the concentrate in circuit at the end of the first quarter following autoclave maintenance at Macraes which resulted in the additional Reefton concentrate being carried over for processing in Q2.

DEVELOPMENT

Didipio Gold - Copper Project (Philippines)

The Didipio Gold and Copper project in Luzon province, Philippines remains under care and maintenance with a reduced workforce at the project site.

The Company is currently evaluating various strategic and funding options for the project and this is currently a key priority for the management team, with good progress being made during the quarter. The mine design optimisation studies are progressing well and are in the final stages of completion.

No lost time injuries (LTI) were recorded during the quarter, similar to the same period last year.

OceanaGold continues to maintain a robust community relations program at the project and the surrounding area and was once again active with a number of initiatives during the quarter.

Two medical missions were hosted in Quirino and Nueva Viscaya provinces which treated more than 850 patients. This innovative and successful program continues to provide much needed medical resources to remote parts of Northern Luzon island and in particularly to residents who otherwise have limited access to healthcare facilities. The program is highly mobile and OceanaGold has been successful on bringing these services to communities across the region treating thousands of patients over the past two years.

The Company also assisted the local Barangay Council of Didipio this year with the annual "Summer League" sports competition. Infrastructure upgrades to some of the sporting venues were undertaken with some of the events also being hosted at the Didipio Community Hall, another infrastructure project which was sponsored by the Company last year.

EXPLORATION

Exploration expenditure for the second quarter totalled $1.9 million bringing the half year total to $3.7 million.

New Zealand

Macraes Goldfield

A 7,000 meter infill drilling program at Frasers Open Cut Stage 5 was completed from all easily accessible areas in the active pit. Additional drilling to further improve the confidence of the reserve for the pit expansion will likely re-start later in the year when other access areas become available.

The Macraes North tenements which are in the northern reaches of the 28 kilometer line of strike for the project have been undergoing an extensive sampling and trenching program over the past nine months. Assays are being evaluated from this program and drill targets are expected to be proposed for the spring drilling season to commence late in Q3.

At the Frasers underground mine, an announcement in May reported on the first five holes of a surface exploration program targeting down-dip extensions to the mineralization at Panel 2. All holes successfully intersected the hanging wall with two holes (RCD 5085, RCD 5090) approximately 250 metres down dip reporting good grades and widths (See Picture A on Page 10). More recently as reported on July 21st, a drill program from the underground exploration drive was successful in starting to confirm continuity between these holes and the current mining area. This program is ongoing.

A 14-hole infill drill program that focused on the southern end of P2 deeps was also completed during the quarter. Assay results that were reported on July 12th, showed good widths and grades beyond the current indicated resource boundary. These results are expected to expand the indicated resource boundary and subsequently the P2 Deeps reserve profile.

A diamond drill program using an air operated Kempe drill commenced during the quarter. This program is targeting extensions to the north and northeast of the current Panel 2 reserve towards the Macraes Fault zone which is a control to confirm mineralization. This program is expected to continue throughout H2 2010.

During the quarter, the exploration drive face was abandoned due to multiple parallel structures making further advance challenging. A new exploration drive has been started further to the north which will provide better access to the remainder of the eastern and north-eastern fringe of Panel 2. This transition has not affected exploration drive drilling, which continued from existing drill chambers.

Reefton Goldfield

A diamond drill program commenced on the first three high priority, near-mine targets identified from a structural mapping program. These targets are within a 2km radius of the Reefton processing plant. Assay results are pending with mineralised structures having been encountered in all drill holes to date.

The first phase of an RC drilling program testing for down-dip extensions to mineralization at the General Gordon, Empress and Souvenir open pits was announced in April. Results point to strong continuity of mineralized structures below the current planned pit floors which is expected to expand the pit shells. A second phase of drilling at General Gordon and Empress commenced during the quarter and results from this program are expected in the third quarter.

During the quarter the regolith sampling ("wacker drilling") program continued to ramp up. This program is targeting the next 14 most prospective targets identified at Reefton and is returning good samples from the bedrock below glacial till and other cover rocks. More than 200 samples from a planned 1,200 sample program have been completed over three targets identified in early Q1. Two crews are making good progress on this program which is ongoing and expected to continue at least until the end of the year.

In late June a $4.4 million increase was announced to the Reefton exploration budget to be spent over the next 18 months. These additional funds will focus on new drill programs targeting potential underground mining targets; a review of the Sam's Creek project to examine the best strategic option to progress this deposit and an increase to the technical staff for the exploration department.

Philippines

Exploration activities in the Philippines during the second quarter focused primarily on the tenements in the far north of Luzon Island along with some Didipio regional work within and outside the area defined by the Didipio FTAA (Financial and Technical Assistance Agreement).

In northern Luzon, sampling and mapping programs continued to follow up on some areas where above normal manganese values were recorded during sampling programs in Q1. Once the complete set of assays is received, analysis will be undertaken to identify possible sources of these anomalies.

The work focused within and surrounding the Didipio FTAA comprised a series of sampling programs some of which have identified new gold and copper anomalies. These are being followed up to better understand the geologic setting and to determine if drill targets can be identified.

RESULTS OF OPERATIONS

Net Earnings

The Company reported a net profit of $7.9 million in the second quarter compared to a net profit of $1.8 million in Q1 2010. Total production of 67,541oz was 3.4% higher than Q1 2010 although 9.0% lower for the comparative period in 2009. Revenue has increased significantly by 66.1% over Q1 2010 and is a result of all sales now being made into the gold spot market after the hedge book was closed out with effect from March 31, 2010. The average gold price received was $1,191 compared to $743 in Q1 when 78.4% of the production was delivered into out of the money hedge contracts.

The impact of non-cash charges for marked to market gains and losses on hedges have in the past been significant. Consequently, EBITDA (earnings before interest, tax, depreciation and amortisation excluding gains/losses on undesignated hedges) and EBIT (earnings before interest and tax before undesignated hedge gains/losses) are reported as measures of operating performance on a consistent and comparable basis.

The Company reported EBITDA before gains/losses on undesignated hedges of $39.2 million compared with $8.5 million in Q1 2010. Higher gold sales revenue from all sales being made at spot rates contributed to this strong operating result.

The EBIT before fair value adjustment of hedges was a profit of $16.9 million compared to a Q1 2010 loss of $12.8 million with improvements a direct function of the increased sales revenue.

Sales Revenue

Gold revenue of $80.2 million was a 66.1% increase over Q1 2010 due to an increase of 3.5% in sales volumes as well as a 60.3% increase in the average price received. The increase in price is a result of sales at spot gold prices after close out of the hedge book in March 2010.

Gold sales volumes for Q2 2010 of 67,347 ounces were 3.5% higher than Q1 2010.

The average gold price received in the quarter increased to US$1,191 per ounce.

Undesignated Hedges Gains/Losses

Undesignated hedge gains and losses calculated as a fair value adjustment of the Company's undesignated hedges are brought to account at the end of each reporting period, and reflect changes in the spot gold price. This also includes adjustments made to take account of gold deliveries into the hedge book, as the derivative liability was released. These valuation adjustments to June 30, 2010, reflect a gain of $16.2 million and compares to $16.2 million at March 31, 2010. After the close out of the hedge book there is only a residual impact from a small number of put options.

Using proceeds from the share placement in March, all forward and call derivative instruments were settled. The Company's current policy is to be unhedged with all gold production sold into the market at spot rates.

Operating Costs & Margins

Cash costs per ounce sold were $564 in Q2, slightly higher than the previous quarter. NZD costs were relatively stable over the quarter with a small increase to diesel prices and maintenance costs along with charges attributable to stock movements. In comparison to the prior year cash unit costs are higher in USD terms due to the exchange rate impact, but also higher due to lower production volumes.

The cash margin of $627 per ounce resulted in earnings before interest, tax, depreciation & amortization (excluding undesignated hedge gains/losses) of $39.2 million for the quarter, compared to $8.4 million in Q1 2010.

Depreciation and Amortization

Depreciation and amortization charges are calculated on a unit of production basis and total $18.5 million for the quarter. These charges were higher than Q1 2010 as there was an increase in pre-strip amortized and allocated to the zones of production.

Depreciation and amortization charges include amortization of mine development, deferred waste stripping costs and depreciation on equipment.

Net Interest expense

The net interest expense of $3.7 million is consistent with Q1 2010 and associated with the project loan, convertible notes and finance leases.

DISCUSSION OF CASH FLOWS

Operating Activities

Cash flows from operating activities decreased to be a net outflow of $21.2 million compared to $10.3 million outflow in Q1 2010. This net outflow includes a payment of $56.7 million to settle the balance of hedge contracts. The operating cash flow before settlements was an inflow of $35.5 million. This increase reflected the higher average gold prices derived from spot gold sales.

Investing Activities

Investing activities were comprised of expenditures for pre-stripping and sustaining capital for the New Zealand operations plus some capitalised holding costs associated with the Didipio Gold - Copper Project.

Cash used for investing activities totaled $21.2 million compared to $18.1 million and $17.9 million in Q1 2010 and Q2 2009 respectively.

Financing Activities

Finance outflows were $4.2 million being largely loan repayments of $1.3 million and lease payments of $2.2 million. The half year inflows include the equity placement in March that raised $79.5 million net of costs.

DISCUSSION OF FINANCIAL POSITION AND LIQUIDITY

Company's funding and capital requirements

For the quarter ended June 30, 2009, the Company earned a net profit of $7.9 million. As at that date the current liabilities of the Company exceeded current assets by $15.2 million. Current liabilities include $46.4 million of convertible notes. Cash flow projections for the near term indicate sufficient funds will be generated to meet all operating obligations at the current forecast gold price.

Commitments

OceanaGold's capital commitments as at June 30, 2010 are as follows:

    
                                                                      Jun 30

    greater than 1 year                                                    -
                                                                    ---------
                                                                      15,326
                                                                    ---------
                                                                    ---------
    

These commitments include equipment associated with a move to owner mining at Frasers underground in addition to orders for long lead time mining equipment as units require replacement. Some of these commitments are expected to be serviced with lease contracts.

There have been no material changes in the capital and operating lease commitments as disclosed in the December 31, 2009 audited financial statements.

Financial position

Current Assets

Current assets have decreased by $61.3 million since Q1 primarily due to cash settlement of hedge contracts for $56.7 million and half year interest payments on convertible notes.

Non-Current Assets

At the end of the quarter, non-current assets were $664.5 million compared to $706.4 million at March 2010. The expenditure on Property, Plant and Equipment, Mining Assets and non-current inventories was broadly in line with depreciation and amortization but there is a decrease on assets due to the strengthening US dollar. Future income tax assets decreased by $2.8 million largely due to utilization of tax losses as well as a decrease in the income tax rate from 30% to 28%.

Current Liabilities

Current liabilities decreased $67.9 million during the quarter. A reduction in accrued liabilities of $56.7 million represented payment of the final balance owing to the bank counterparties that provided derivative instruments. In addition, interest bearing loans decreased due to final payment of the project loan and the benefit from the strengthening US dollar.

Non-Current Liabilities

Non-current liabilities are $194.0 million at June 30 2010 and have reduced by $16.5 million since March 31, 2010. This is due to a decrease in future tax liabilities of $6.6 million combined with the translation benefit from a strengthening US dollar.

Derivative Assets / Liabilities

OceanaGold settled derivative instruments in relation to 74,880 ounces under forward gold sales contracts and 78,018 ounces under gold put options at the end of March 2010.

CRITICAL ACCOUNTING ESTIMATES AND ACCOUNTING POLICIES

The accounting policies that involve significant management judgment and estimates are discussed in this section. For a complete list of the significant accounting policies, reference should be made to Note 1 of the 2009 audited consolidated financial statements of OceanaGold Corporation.

Exploration and Evaluation Expenditure

Exploration and evaluation expenditure is stated at cost and is accumulated in respect of each identifiable area of interest.

Such costs are only carried forward to the extent that they are expected to be recouped through the successful development of the area of interest (or alternatively by its sale), or where activities in the area have not yet reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable resources, and active work is continuing.

Accumulated costs in relation to an abandoned area are written off to the Statement of Operations in the period in which the decision to abandon the area is made.

A regular review is undertaken of each area of interest to determine the appropriateness of continuing to carry forward costs in relation to that area of interest.

Mining Properties in Production or Under Development

Expenditure relating to mining properties in production and development are accumulated and brought to account at cost less accumulated amortisation in respect of each identifiable area of interest. Amortisation of capitalised costs, including the estimated future capital costs over the life of the area of interest, is provided on the production output basis, proportional to the depletion of the mineral resource of each area of interest expected to be ultimately economically recoverable.

Costs associated with the removal of overburden and other mine waste materials that are incurred in the production phase of mining operations are included in the costs of inventory in the period in which they are incurred, except when the charges represent a betterment to the mineral property. Charges represent a betterment to the mineral property when the stripping activity provides access to reserves that will be produced in future periods that would not have been accessible without the stripping activity. When charges are deferred in relation to a betterment, the charges are amortized over the reserve in the betterment accessed by the stripping activity using the units of production method.

A regular review is undertaken of each area of interest to determine the appropriateness of continuing to carry forward costs in relation to that area of interest. Should the carrying value of expenditure not yet amortised exceed its estimated recoverable amount, the excess is written off to the Statement of Operations.

Asset Retirement Obligations

OceanaGold recognises the fair value of future asset retirement obligations as a liability in the period in which it incurs a legal obligation associated with the retirement of long-lived assets that results from the acquisition, construction, development and/or normal use of the assets. OceanaGold concurrently recognises a corresponding increase in the carrying amount of the related long-lived asset that is depreciated over the life of the asset.

The key assumptions on which the fair value of the asset retirement obligations are based include the estimated future cash flow, the timing of those cash flows and the credit-adjusted risk-free rate or rates on which the estimated cash flows have been discounted. Subsequent to the initial measurement, the liability is accreted over time through periodic charges to earnings. The amount of the liability is subject to re-measurement at each reporting period if there has been a change to the key assumptions.

Asset Impairment Evaluations

The carrying values of exploration, evaluation, mining properties in production or under development and plant and equipment are reviewed for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. If any such indication exists and where the carrying value exceeds the undiscounted future cash flows from these assets, the assets are written down to the fair value of the future cash flows based on OceanaGold's discount rate of the asset.

Derivative Financial Instruments/Hedge Accounting

The consolidated entity can use derivative financial instruments to manage commodity price and foreign currency exposures from time to time.

Derivative financial instruments are initially recognised in the balance sheet at fair value and are subsequently re-measured at their fair values at each reporting date.

The fair value of gold hedging instruments is calculated by discounting the future value of the hedge contract at the appropriate prevailing quoted market rates at the reporting date. The fair value of forward exchange contracts is calculated by reference to current forward exchange rate for contracts with similar maturity profiles.

Certain derivative instruments do not qualify for hedge accounting or have not been accounted for as fair value or cash flow hedges. Changes in the fair value of these derivative instruments are recognised immediately in the statement of operations. The company does not have any designated hedges.

Stock Option Pricing Model

Stock options granted to employees or external parties are measured by reference to the fair value at grant date and are recognised as an expense in equal installments over the vesting period and credited to the contributed surplus account. The expense is determined using an option pricing model that takes into account the exercise price, the term of the option, the impact of dilution, the non-tradable nature of the option, the current price and expected volatility of the underlying share, the expected dividend yield and the risk free interest rate for the term of the option.

Income Tax

The Group follows the liability method of income tax allocation. Under this method, future tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the substantially enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided to the extent that it is more likely than not that those future income tax assets will not be realised.

Foreign Currency Translation

The consolidated financial statements are expressed in United States dollars ("USD") and have been translated to USD using the current rate method described below. The controlled entities of OceanaGold have either Australian dollars ("AUD"), New Zealand dollars ("NZD") or United States dollars ("USD") as their functional currency.

OceanaGold employs the current rate method of translation for its self-sustaining operations. Under this method, all assets and liabilities are translated at the period end rates and all revenue and expense items are translated at the average exchange rates for recognition in the statement of operations. Differences arising from these foreign currency translations are recorded in shareholders' equity as a cumulative translation adjustment.

OceanaGold employs the temporal method of translation for its integrated operations. Under this method, monetary assets and liabilities are translated at the period end rates and all other assets and liabilities are translated at applicable historical exchange rates. Revenue and expense items are translated at the rate of exchange in effect at the date the transactions are recognized in the statement of operations, with the exception of depreciation and amortization which is translated at the historical rate for the associated asset. Exchange gains and losses on currency translation adjustments are included in the statement of operations.

ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with Canadian GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and related notes. Significant areas where management's judgment is applied include ore reserve and resource determinations, exploration and evaluation assets, mine development costs, plant and equipment lives, contingent liabilities, current tax provisions and future tax balances and asset retirement obligations. Actual results may differ from those estimates.

RISKS AND UNCERTAINTIES

This document contains some forward looking statements that involve risks, uncertainties and other factors that could cause actual results, performance, prospects and opportunities to differ materially from those expressed or implied by those forward looking statements. Factors that could cause actual results or events to differ materially from current expectations include, among other things: volatility and sensitivity to market prices for gold; replacement of reserves; procurement of required capital equipment and operating parts and supplies; equipment failures; unexpected geological conditions; political risks arising from operating in certain developing countries; inability to enforce legal rights; defects in title; imprecision in reserve estimates; success of future exploration and development initiatives; operating performance of current operations; ability to secure long term financing and capital, water management, environmental and safety risks; seismic activity, weather and other natural phenomena; failure to obtain necessary permits and approvals from government authorities; changes in government regulations and policies including tax and trade laws and policies; ability to maintain and further improve labour relations and other development and operating risks.

For further detail and discussion of risks and uncertainties refer to the Annual Information Form available on the Company's website.

CHANGES IN ACCOUNTING POLICIES INCLUDING INITIAL ADOPTION

There have been no material changes from the accounting policies of FY2009.

Adoption of new accounting policies

The CICA issued three new accounting standards in January 2009: Section 1582, "Business Combinations", Section 1601, "Consolidated Financial Statements" and Section 1602, "Non-Controlling interests". These new standards will be effective for fiscal years beginning on or after January 1, 2011. The Company is in the process of evaluating the requirements of the new standards.

Section 1582, "Business Combinations" replaces section 1581, "Business Combinations", and establishes standards for the accounting for a business combination. It provides the Canadian equivalent to IFRS 3 - "Business Combinations". The section applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after January 1, 2011.

Sections 1601, "Consolidated Financial Statements", and 1602, "Non-Controlling interests", together replace section 1600, "Consolidated Financial Statements". Section 1601 establishes standards for the preparation of consolidated financial statements and applies to interim and annual consolidated financial statements relating to fiscal years beginning on or after January 1, 2011.

Section 1602 "Non-Controlling interests" establishes standards for accounting for non-controlling interest in a subsidiary in consolidated financial statements subsequent to a business combination. It is equivalent to the corresponding provisions of IFRS 27 - "Consolidated and Separate Financial Statements" and applies to interim and annual consolidated financial statements relating to fiscal years beginning on or after January 1, 2011.

Accounting policies effective for future periods

International Financial Reporting Standards ("IFRS")

The Canadian Institute of Chartered Accountant's (CICA's) Accounting Standards Board announced that publicly accountable enterprises will be required to adopt IFRS effective January 1, 2011. At the effective date, the balance sheet as at January 1, 2010 will require conversion to IFRS to establish opening balances which will form the basis for comparative information to be reported in 2011.

OceanaGold Corporation has continued to work on its transition to IFRS, including assessment of the impact on its accounting systems and financial statements. The conversion project includes review of project team, governance, resources, key CGAAP to IFRS differences, accounting policies and an implementation plan. The financial reporting impact of transitioning to IFRS is currently being evaluated and the quantitative impact has not been fully determined at the date of this report.

The following table summarises the key activities in the transition plan and the current status.

First-time adoption of IFRS

IFRS 1 requires that an entity apply all standards effective at the end of its first IFRS reporting period retrospectively. However, IFRS 1 does provide certain mandatory and limited optional exemptions in specific areas of certain standards that will not require retrospective application of IFRS. The most significant exemptions which are expected to apply in preparation of the company's first consolidated financial statements under IFRS are summarised as follows:

Accounting Estimates

Accounting estimates applied in accordance with IFRS at the date of transition should be consistent with estimates in accordance with Canadian GAAP unless there is objective evidence that estimates were in error.

Business Combinations

IFRS allows guidance under IFRS 3R Business Combinations to be applied retrospectively or prospectively. OceanaGold expects adopt IFRS 3 prospectively.

Asset Retirement Obligations (ARO)

IFRIC 1 requires changes in decommissioning liabilities to be included in the cost of the asset and depreciated. A first-time adopter has an option to a simplified approach to calculate and record the asset related to the ARO. OceanaGold's existing approach complies with recognition and measurement of decommissioning liabilities under IFRS, including recording the liability in the cost of the asset, by discounting the liability to the date when it first arose, and depreciating the asset to transition date. There will be no change on transition to IFRS.

Property, Plant and Equipment

There is an option to record property, plant and equipment at fair value on transition to IFRS. This fair value becomes the deemed cost of the asset for reporting under IFRS. OceanaGold is not planning to use this election and property, plant and equipment will continue to be recorded under the cost model, at the carrying amounts, on the date of transition to IFRS.

Cumulative translation differences

IAS 21, The Effects of Changes in Foreign Exchange Rates, requires an entity to determine the translation differences in accordance with IFRS from the date on which a subsidiary was formed or acquired. IFRS 1 allows cumulative translation differences for all foreign operations to be deemed zero at the date of transition to IFRS, with future gains or losses on subsequent disposal of any foreign operations to exclude translation differences arising from periods prior to the date of transition to IFRS. OceanaGold expects to use this exemption and existing cumulative translation differences will be transferred to retained earnings on transition to IFRS.

Key Differences - Canadian GAAP to IFRS

In addition to the exemptions and exceptions discussed above, the following explains the key areas where changes in accounting policies could have significant differences between Canadian GAAP and IFRS as they apply to OceanaGold consolidated financial statements:

Impairment

Canadian GAAP - A recoverability test is performed by first comparing the undiscounted expected future cash flows to be derived from the asset to its carrying amount. If an asset's undiscounted expected future cash flows do not exceed its carrying value, an impairment loss is calculated as the excess of the asset's carrying amount over its fair value (on a discounted basis).

IFRS - A recoverability test is performed by comparing the carrying amount to the asset's recoverable amount. The impairment loss is calculated as the excess of the asset's carrying amount over its recoverable amount. The recoverable amount is defined as the higher of the asset's fair value less costs to sell and its value-in-use. The expected future cash flows from the asset are discounted to their net present value in the recoverable amount test. As a result of this difference in measurement methodology, impairments under IFRS are more likely.

With the Didipio project currently on care and maintenance there is potential for material impairment to be required on its assets.

Foreign Exchange Translation

Canadian GAAP - Distinction is made between integrated and self sustaining foreign operations with the temporal and the current rate methods of translation applied respectively.

IFRS - A functional and presentation currency approach is taken to foreign exchange translation and no distinction is made between integrated and self sustaining foreign operations. Where the functional currency of an entity is different from the presentation currency, an approach similar to the current rate method under CGAAP is applied. The key elements are:

    
    -   Assets and liabilities are translated at the balance date exchange
        rate.

    -   Income and expenses are translated at the exchange rate at the date
        of the transaction although an average rate may be applied as a proxy
        in many circumstances.

    -   All resulting currency exchange differences are recognised in the
        Foreign Currency Translation Reserve (FCTR) within other
        comprehensive income.
    

The most significant differences for OceanaGold are likely to be in relation to the Philippines operations which are currently being treated as an integrated foreign operation under CGAAP. There will be no change in the current treatment of New Zealand operations which are classified self-sustaining under CGAAP.

Income tax

Canadian GAAP - The amount that a future income tax asset is recognised at is limited to the amount that is more likely than not to be realised. Future taxes are split between current and non-current components on the basis of either (1) the underlying asset or liability or (2) the expected timing reversal of items when not related to an asset or liability.

IFRS - Deferred tax assets are recognised in their entirety when it is probable that sufficient future taxable profit will be available to recover the asset. All deferred tax assets and liabilities will be classified as non-current.

OceanaGold does not expect there to be changes in the deferred tax assets currently recognised. The impact of the differences on transition will be limited to reclassification of current deferred tax liabilities and assets to non-current classification.

Other Business Considerations

The transition to IFRS may also have an impact on some contractual obligations. Management will have more insight on the effects to other business considerations once the full impact of transition has been quantified.

The most significant factors causing variation in the results are the commissioning of both the Reefton open pit and Frasers underground mines, the variability in the grade of ore mined from the Macraes open pit mine and variability of cash cost of sales due to the timing of waste stripping activities. The volatility of the gold price has a significant impact both in terms of its influence upon gold sales revenue and its impact upon undesignated gains/(losses) on hedges. Adding to the variation are the large movements in foreign exchange rates between the USD and the NZD.

As noted in the December 2008 MD&A an adjustment in the fourth quarter 2008 to the pre-stripping account is reflected in the "December 2008" quarter above. If the adjustment is updated to the quarter to which it relates there is an equal and offsetting effect increasing Q2 2008 EBITDA by $4.9 million, earnings after tax and net earnings by $3.4 million and earnings per share by $0.02. This is considered a timing difference and therefore not significant with the details and analysis provided above.

NON-GAAP MEASURES

Throughout this document, we have provided measures prepared according to Canadian generally accepted accounting principles ("GAAP"), as well as some non-GAAP performance measures. As non-GAAP performance measures do not have any standardized meaning prescribed by GAAP, they are unlikely to be comparable to similar measures presented by other companies.

We provide these non-GAAP measures as they are used by some investors to evaluate OceanaGold's performance. Accordingly, such non-GAAP measures are intended to provide additional information and should not be considered in isolation, or a substitute for measures of performance in accordance with GAAP.

Earnings before interest, tax, depreciation and amortization (EBITDA) is one such non-GAAP measure and a reconciliation of this measure to net earnings/(losses) is provided on page 10.

Cash and non cash costs per ounce are other such non-GAAP measures and a reconciliation of these measures to cost of sales, including depreciation and amortization, is provided on the next page.

DISCLOSURE CONTROLS AND PROCEDURES

The Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of the Company's disclosure controls and procedures as at June 30, 2010. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective as at June 30, 2010 to provide reasonable assurance that material information relating to the Company, including its consolidated subsidiaries, would be made known to them by others within those entities.

INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of OceanaGold, including the Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of the design and operation of the Company's of the internal controls over financial reporting and disclosure controls and procedures as of June 30, 2010.

Based on this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that they were effective at a reasonable assurance level.

There were no significant changes in the Company's internal controls, or in other factors that could significantly affect those controls subsequent to the date the Chief Executive Officer and Chief Financial Officer completed their evaluation, nor were there any significant deficiencies or material weaknesses in the Company's internal controls requiring corrective actions.

The Company's management, including the Chief Executive Officer and the Chief Financial Officer does not expect that its disclosure controls and internal controls over financial reporting will prevent all errors and fraud. A cost effective system of internal controls, no matter how well conceived or operated, can provide only reasonable not absolute, assurance that the objectives of the internal controls over financial reporting are achieved
