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

(All references in US Dollars)

MELBOURNE, Australia, July 26, 2012 /CNW/ - OceanaGold Corporation (ASX: OGC) (TSX: OGC) (NZX: OGC) (the "Company") has reported EBITDA (earnings before interest, taxes, depreciation and amortisation) of $25.6 million, a 10% increase on the previous quarter.

In its Second Quarter 2012 Results released today, the Company also reported a 10% increase in gold production over the first quarter, with 55,709 ounces produced.

Revenue for the quarter was $86.7 million from an average gold price received of $1,613 per ounce, a 2% decrease over Q1 due to the lower gold price received offsetting higher ounces sold. Gold sales volumes for the second quarter remained solid reaching 53,756 ounces, versus the previous quarter's 51,852 ounces.

A second quarter improvement in the operating cash cost per ounce to $1,029 against $1,126 in the first quarter was due to favourable foreign exchange rate movements and an increase in gold ounces produced.

First half 2012 revenue was $175.3 million from sales of 105,608 ounces of gold at a cash cost of $1,077 per ounce sold. The Company's cash balance at June 30, 2012 was $73 million with credit approval secured for a $220 million facility, announced in July.

The Didipio Project in the Philippines continued to make strong progress throughout the period with construction now 70% complete and the Project is fully funded through to operations and on track for commissioning in fourth quarter 2012.

The Company invested $3.9 million on exploration during the quarter with $3.5 million incurred in New Zealand where positive results were encountered at its Blackwater Underground mine, the Macraes Open Pit reserve and the Round Hill deposit.

OceanaGold CEO, Mick Wilkes, said the Company's second quarter results supported its expectation of quarter on quarter improvement in 2012.

"The New Zealand operations achieved good production improvement this quarter and remain on track to meet the full year guidance. Didipio construction is at peak levels and progressing on schedule to commission in the fourth quarter of 2012 and with the strong support from our new financial partners we are moving closer to achieving our long term strategic targets. 

Other highlights from the OceanaGold Second Quarter 2012 Results include:

• Established a Toronto office and full time Investor Relations Manager (North America) to better service the Company's TSX listing and North American investment community.
  
  
• Awarded a commendation from the Director of the Commission of Human Rights Region 02 in the Philippines as part of the Commission's 25^th anniversary.

OVERVIEW

Results from Operations

OceanaGold recorded revenue of $86.7 million in the second quarter of 2012 from sales of 53,756 ounces of gold at a cash cost of $1,029 per ounce. Revenue for the first half of 2012 was $175.3 million from sales of 105,608 ounces of gold at cash cost of $1,077 per ounce sold.

Gold production for the second quarter of 2012 was 55,709 ounces, up 10% versus 50,842 ounces in the previous quarter. This increase was driven by improved production from Macraes Open Pit and Reefton Open Pit mines with higher mill throughput and higher mill feed grades partly offset by lower recoveries. Total production achieved for the first half of 2012 was 106,551 ounces of gold.

The average gold price received in the second quarter of 2012 was $1,613 per ounce and versus $1,708 per ounce in the first quarter. Operating cash cost per ounce sold improved to $1,029 versus the prior quarter of $1,126. The decrease in cash cost per ounce sold was due to favourable foreign exchange rate movements and an increase in gold ounces produced. Review of cost management is continuing as part of the Company's Performance Management Program. The cash operating margin of $584 per ounce sold was comparable to the prior quarter with lower average gold price received offset by lower cash operating cost per ounce.

Total material mined was up 4% in the second quarter to 15.6 million tonnes compared to the previous quarter with a good increase in ore tonnes mined and improvements in truck availability at both Macraes and Reefton Goldfields.

Mill throughput for the second quarter increased by 6% to 1.91 million tonnes versus the first quarter. The mill feed grade also improved by 6% to 1.15 g/t from 1.08 g/t in the prior quarter with improved feed grades from Macraes Open Pit and Reefton mines.

The overall recovery for the second quarter was 79.0%, representing a 3% decrease from the previous quarter's recovery of 81.4%. The decrease was attributable to lower flotation recovery and higher autoclave throughput rates resulting in lower oxidation rates and lower carbon-in-leach recovery at Macraes. The processing of some oxide ore at Reefton was also a contributor.

Cash flow from operations for the second quarter was $20.9 million and $41.7 million for the half year. The cash balance at the end of the quarter was $73.1 million.

Drilling of the inferred resource to the south and east of Macraes Open Pit has produced encouraging results with the potential to increase resource and reserves. Resource and reserve modelling is in progress.

Production & Cost Guidance

In December 2011, the company reported FY2012 production guidance set at 230,000 - 250,000 ounces of gold at cash costs of $900 - $980 per ounce (assumes NZD/USD exchange rate of $0.80).

Overall, the Company expects gold production in the second half of the year to be greater than the first half as the production of the higher grade gold from Frasers Stage 5 at Macraes Goldfields commences, Frasers Underground returns to normal operating levels following the development of the new access and increased mining rates at Reefton.   Full year 2012 production guidance of 230,000 to 250,000 ounces of gold remains unchanged.

As expected, first half cash operating costs fell outside of the full year guidance range of $900 to $980 per ounce.  As production levels in the second half increase, cash costs are expected to fall below the average for the first half. Full year cash cost guidance remains unchanged.

Didipio Project

During the second quarter of 2012, construction remained on schedule and is now over 70% complete. The majority of the process plant structural steel has been installed along with the mills, flotation cells and other major mechanical equipment. Electrical works have also begun with the installation of the first power generating units.

Open pit mining continued to provide competent waste rock for construction of the Tailings Storage Facility (TSF), which is well underway, road sheeting, and other construction purposes. The mining of oxide mineralisation commenced at the top of the ore body. Ore mining will commence early third quarter. The mining contractor has started to take delivery of the large mining fleet and all equipment is due to arrive on site over the next few months on schedule.

The TSF construction is tracking to schedule and is now 50% complete. The critical activity of bringing in the embankment foundations for the TSF up and out of the ground has been completed prior to the onset of rain.

All major construction contracts have been awarded with the contractors mobilised to site and the final long lead time items have arrived in the Philippines and are being transported to site.

There are currently over 1,700 contractors and employees on site engaged in construction and mining activities, of which 98% are Filipinos. The permanent operations accommodation village is now complete and the accommodation on site is nearing full capacity.

During the quarter, $52.5 million was spent on construction. Total spend since the project recommenced in June 2011 was $161.0 million with a further $24 million committed in contracts. Subsequent to quarter end, the Company announced the Didipio Project capital costs are now expected to be $220 million representing a 19% increase on the $185 million reported at project recommencement in June 2011. The Company also announced that it has secured credit approvals from a group of large multinational banks for a $220 million credit facility which includes a $50 million working capital facility. The project is fully financed and on track for commissioning in fourth quarter 2012.

During the quarter, the Company advanced 30% of the 2013 Social Development and Management Plan (SDMP) funds to the nine surrounding local communities who have begun implementation of their priority community development projects. The local community development corporation formed in 2011 ("DiCorp") continued work on their awarded contracts such as road maintenance and transport services and the company continued its sponsorship and participation of the medical missions. In May, the Company received a commendation award from the Director of the Commission of Human Rights Region 02 in the Philippines as part of its 25th anniversary for "incorporating and observing a human rights perspective in the conduct of its business affairs..."

Exploration

The Company invested $3.9 million on exploration during the second quarter with the majority ($3.5 million) incurred in New Zealand.

At Reefton in New Zealand, exploration during the quarter focused on greenfields and brownfields exploration drilling. Diamond drill rigs continued deep drilling programs at the Globe Progress Mine and Blackwater historical mine during the quarter. Helicopter assisted diamond drilling was conducted at Blackwater North.

In April, the Company announced deep drilling at the historic Blackwater Underground mine successfully intersected the reef at 391m below the old workings (drill hole WA21A). Assay results of 0.5m (true width) grading 23.3 g/t gold are consistent with historical mining records. A second hole commenced in late March to test the reef along strike to the north at a similar depth below the workings.

Exploration continued at the Frasers Underground mine with mineralisation being confirmed to the north and northeast of the current workings. Mineralisation remains open in both directions. Exploration drilling will continue in the down dip areas of Panel 2 of the underground to convert inferred resources to reserves.

Surface drilling programs at the Macraes Goldfield targeted blind mineralisation located immediately to the east (down dip) of the Frasers Underground mine and between 2.5 to 6.0 kilometres north of Macraes Open Pit (including Innes Mills, Round Hill and Coronation South projects).

Philippines exploration continued to focus on the FTAA exploration area. The copper-gold soil geochemical anomalies at the MMB, TNN, and D'Beau prospects have been further defined through infill sampling and expanded through additional wide-spaced sampling. Future work will focus on further defining drill targets at the MMB and TNN prospects.

Subsequent to quarter end, the Philippines Government released an Executive Order (EO79) in regards to the Philippines mining sector reform. As a result of EO79, the granting of exploration permits is expected to resume and the Company remains in "drill ready" status for some near mine prospects at the Didipio Project and awaits extension of its exploration period of its granted Financial or Technical Assistance Agreement (FTAA).

* Cash operating costs per ounce has been adjusted in 2012 to reflect the decision to combine the administrative functions of the Melbourne, Dunedin and Makati offices under single management from 1 January 2012.  In particular, previously the activities of the Dunedin office, such as finance, legal, regulatory, information technology, technical and supply services were treated as part of mine operating costs.  With the start-up of the Didipio operations scheduled for Q4 2012, this change reflects the development of the business into a multi-regional mining company.

PRODUCTION

Gold production for the second quarter of 2012 was 55,709 ounces, up 10% versus 50,842 ounces in the previous quarter.  This increase was driven by improved production from Macraes Open Pit and Reefton Open Pit mines as a result of higher mill throughput and higher mill feed grade, partly offset by lower recoveries. At the Frasers Underground mine, production in the second quarter was slightly below the first quarter due to slightly lower mill feed grade. Stope production improved as a new access was developed to areas that were inaccessible due to the greater than expected ground movement reported in the first quarter.  The Frasers Underground mine production is expected to return to normal levels in the second half of the year. Total production for the first half of 2012 was 106,551 ounces of gold.

Overall, the Company expects gold production in the second half of the year to be greater than the first half as the production of the higher grade gold from Frasers Stage 5 at Macraes Goldfield commences, Frasers Underground returns to normal operating levels following the development of the new access and increased mining rates at Reefton.

Cash operating costs for the second quarter of 2012 were $1,029 per ounce sold versus $1,126 per ounce in the first quarter.  The decrease of cash costs from the previous quarter was mainly due to favourable movement in foreign exchange rates and an increase in ounces of gold produced.

OPERATIONS

Macraes Goldfield (New Zealand)

The Macraes operations (Open Pit and Underground) incurred one lost time injury (LTI) during the quarter when an articulated 30-tonne dump truck partially rolled in slippery road conditions. Appropriate action has been taken to address driver safety.

Production from the Macraes Goldfield for the quarter was 39,012 gold ounces compared to 34,851 gold ounces the previous quarter. The improved production was due to higher mill throughput and higher mill grade in particular from Macraes Open Pit.

Total material mined from Macraes Open Pit was 10.3 million tonnes in the quarter, up 2% on the previous quarter, mainly due to an increase in ore tonnes mined and improved truck availability.

Mining continued in the Frasers 5 cutback and a small cutback to the west with the overburden material hauled to the Frasers East and Frasers West waste dumps.

At Frasers Underground, mining was carried out in Panel 2. Total ore mined for the quarter was 179,000 tonnes, an improvement of 14% on the first quarter in 2012. Stope production improved during the quarter as new access was developed to areas that were rendered inaccessible during the first quarter due to greater than expected ground movement as previously reported. Ore production levels from the underground are expected to return to normal rates in the second half of 2012.

Mill throughput was 1.48 million tonnes, an increase of 6% when compared to 1.39 million tonnes in the previous quarter. Mill feed grade for the quarter improved by 5% to 1.03g/t, versus the prior quarter of 0.98g/t. The higher mill grade was due to better grades mined from the bottom of the Macraes Open Pit.

The process plant recovery in the second quarter was 79.1% compared to 80.8% the previous quarter mainly due to lower flotation recoveries and targeting of higher autoclave throughput rates in order to reduce concentrate stock levels. This resulted in lower oxidation rates and lower CIL recovery.

Encouraging results from infill drilling in the south wall and east wall of Macraes Open Pit indicates potential to increase current resources and reserves. Best results for the Macraes east wall drilling include: RCH5531 11m @ 1.86 g/t from 131m, RCH5536 12m @ 3.23 g/t from 166m, and RCH5539 22m @ 1.36 g/t from 179m. Results of the south wall drilling are pending.

Reefton Goldfield (New Zealand)

There was one lost time injury (LTI) during the quarter at the Reefton Operations which was attributable to a mine operator slipping off the steps climbing onto a truck and spraining an ankle. An Incident Cause Analysis Method (ICAM) investigation was completed.

Significant improvements to Reefton's health and safety programs have been implemented following the two safety audits in the first quarter. In addition with the appointment of a Health, Safety & Training Manager for Reefton this site has seen a stronger focus on procedures and the use of safety tools.

Gold produced for the quarter was 16,697 ounces, up 4% over the first quarter. The improvement was due to increased throughput and higher feed grade partly offset by lower recoveries caused by trial processing of some stockpiled oxide ore.

Total material mined was up 6% to 5.0 million tonnes in the quarter versus 4.7 million tonnes in the first quarter due to increased capacity and mechanical availability of fleet, as expected following improvements implemented in the prior quarter. Mining resumed at Souvenir Pit during the quarter following granted consents with the required cutback of the south wall. Mining of ore at Souvenir is expected to resume in the third quarter.

The total ore mined for the second quarter was 268,365 tonnes versus 319,112 tonnes in the prior quarter. The decrease in ore mined was due to less ore tonnes than was predicted by the resource model. On a short term basis there are variations, both positive and negative, in the resource model, however over the long term, the model is performing well.

During the second quarter, hired mining equipment was removed from Reefton and replaced by four the CAT 785 Haul trucks and ancillary equipment from Macraes.

Process plant throughput in the second quarter increased by 4% to 431,921 tonnes, versus the previous quarter of 414,644 tonnes.

Grade through the mill improved to 1.53 g/t in the second quarter versus 1.44 g/t in the prior quarter as a result of oxide ore being treated from the stockpiles. The oxide ore is of higher grade however the recovery of this oxide material is lower.

Gold recovery was 78.8% versus 83.2% in the previous quarter due to processing of oxide ore.

DEVELOPMENT

Didipio Project (The Philippines)

There was one lost time injury (LTI) in the quarter, the second for the project, and shortly after achieving over one million man hours without a LTI.

Subsequent to quarter end, the Company regrettably announced the fatality of a contractor in an incident arising from a recent severe storm that impacted on the site. OceanaGold has arranged counselling and support services to be available for the family of the deceased and affected fellow employees in relation to this incident. Appropriate action will be undertaken to ensure that such incidents do not occur again.

Construction progress remained on track and is now over 70% complete. The majority of the process plant structural steel has been installed along with the mills, flotation cells and other major mechanical equipment. Electrical works have begun with the installation of the first power generating units.

Concrete foundations were 95% complete by the end of the quarter and will be fully complete on the process plant in the third quarter. All structural concrete foundations for the major areas have been completed. Steel erection is progressing well with over 65% of the process plant steel installed including milling, crushing and conveying steelwork. Mechanical, piping and electrical works have now begun on schedule with major mechanical equipment such as the cyclone cluster, flotation cells and pumps already in place.

Open pit mining continued in the quarter from the Bacbacan starter pit to provide competent waste rock for construction of the Tailings Storage Facility (TSF), road sheeting, and other construction purposes. The mining of a 20m thick oxide mineralisation commenced at the top of the outcropping ore body late in the quarter.  First ore is expected to be mined in the third quarter. The mining contractor has started to take delivery of the large mining fleet and the first Komatsu HD785 trucks (100 tonne capacity) have begun to arrive on site. The remaining equipment is expected to arrive over the next few months on schedule.

The TSF construction is on schedule and now 50% complete. The critical activity of bringing in the embankment foundations up and out of the ground has been completed prior to the onset of rain. TSF construction can now continue unabated through wet weather.

All major construction contracts have been awarded and all contractors have now mobilised to site.

The switch rooms, being the final large items of equipment, were shipped during the quarter and are in port at Manila ready for transportation to site.

There are currently over 1,700 contractors and employees on site engaged in construction activities, of which over 98% are Filipinos. Construction of the permanent accommodation village was completed during the quarter and along with the construction camps, accommodation of over 1,100 beds on site is nearing capacity. Of the remaining staff, 500 are from the local community and the rest are being billeted with families in the local community.

During the quarter, $52.5 million was spent on the construction. Total spend on construction since the project recommenced in June 2011 was $161.0 million, with a further $24 million committed in contracts. Subsequent to quarter end, the Company provided an update of the capital cost of the Didipio Project which is now expected to be $220 million which represents a 19% increase on the $185 million reported at project recommencement in June 2011. The Company also announced that it has secured credit approvals from a group of large multinational banks for a $220 million credit facility which includes a $50 million working capital facility. The project is fully financed and on track for commissioning in fourth quarter 2012.

As part of its Financial or Technical Assistance Agreement (FTAA) at Didipio, the Company is committed to developing a Social Development and Management Plan (SDMP) and commit 1.5% of its operating costs to funding initiatives under the SDMP.  The SDMP benefits are shared amongst the host community (Didipio) and nine other upstream and downstream communities.  During the quarter, the Company advanced 30% of the 2013 SDMP funds to the nine communities who have begun implementation of their priority community development projects. An agreement has been reached with the neighbouring barangay to improve an access road to that community at an expected cost of $400,000. Construction will commence in the third quarter and take 12 months to complete.

In the second quarter of 2012, the local community development corporation formed in 2011 ("DiCorp") continued work on ongoing maintenance of the access road, waste and recycling services, employee transport services, equipment hire and construction services.  Planning is underway for DiCorp to take on the contract for the camp laundry and cleaning services in the third quarter.

As part of OceanaGold's commitments in the Memorandum of Agreement with the Didipio Community, the Company funded construction of a major drainage canal through the community to prevent flooding which was completed during the second quarter. A second project involving road widening, slope stabilisation, and drainage is underway along the central road through the Didipio community.

The Company also continued its sponsorship and participation in number of medical missions in the surrounding villages, which have benefitted over 8,600 people since the inception of the program.

The Didipio Project was proud to receive a commendation in the last three months from the Director of the Commission of Human Rights Region 02 in the Philippines as part of its 25^th anniversary. The Plaque of Recognition was for "incorporating and observing a human rights perspective in the conduct of its business affairs and for giving due consideration to cultural rights as well as the social development of the Barangays impacted by its mining operations within the Provinces of Nueva Vizcaya and Quirino".

EXPLORATION

New Zealand

Exploration expenditure in New Zealand was $3.5 million during the second quarter and $7.0 million for the half year.

Reefton Goldfield - New Zealand

The deep drill programs at the Globe Progress Mine and Blackwater historical mine continued throughout the second quarter. Helicopter assisted diamond drilling was conducted at Blackwater North.

The deep drilling program at the historic Blackwater Underground mine commenced in November 2011. Drill hole WA21A successfully intersected the reef at 1,316 metres down hole and approximately 652m down-plunge (391 vertical metres) from the base of the old workings. In April, the Company announced results from WA21A of 1.0m (estimated true width of 0.5m) grading 23.3 g/t Au. These results were consistent with the average grade and thickness obtained from historical mining records. A new hole WA22 commenced in late March to test the reef along strike to the north at a similar depth below the workings. Drilling is currently at a depth of 861m. The program is expected to continue throughout 2012.

An 18 drill hole program commenced at Globe Progress in the fourth quarter of 2011 with one hole remaining to be drilled. Ten of the drill holes consolidate mineralisation within the Globe Open Pit while eight test extensions, known as Globe Deeps, beneath the final pit design. Assay results have been received for 2 of the 18 holes: RCD0015 and RCD0018 (Table A). Both tested open pit targets. RCD0015, returned 12m @ 2.60 g/t Au from 229m, while RCD0018, returned 14m @ 2.63 g/t Au from 302m. The assay results from all drill holes are expected to be received and integrated into a revised resource model during the third quarter.

A seven hole diamond drill program was completed during the first quarter at the Big River South prospect located 11km to the south of the Reefton processing plant. Assay results for the final two Big River South diamond drill holes (BRS006 and BRS007) were received during the quarter. Best results include 1m (down hole) @ 5.49 g/t Au from 84m in BRS006 and 6m (down hole) @ 0.85 g/t Au from 28m depth and 1m (down hole) @ 2.61 g/t Au from 71m depth in hole BRS007 (Table B).

At Blackwater North, a three hole (WN0003 to WN0005) 533m, helicopter-assisted diamond drilling program was completed in the second quarter targeting potential strike extensions under cover, 500m north along strike from the historic Blackwater Underground mine. The area is located 14 kilometres SSW of the Reefton processing plant. No significant assay results were returned.

Drilling in the Krantz Creek Exploration Permit (EP) 40 705 will commence in the third quarter targeting coincident gold and arsenic geochemical anomalies within the Krantz Creek shear.

Mapping is continuing in the Blackwater and Capleston tenements with the aim of defining potential narrow, high-grade Blackwater-style targets.

Two prospecting permit applications (PPA) were submitted during the quarter; namely, Boatmans PPA 54 444 and Lyell PPA 54 446. The Boatmans PPA 54 444 is contiguous with existing Exploration Permits and the Lyell PPA 54 446 is located 50 kilometres north of the Reefton processing plant. The Soldiers Flat EP 50 700 was relinquished.

Macraes Goldfield

Underground exploration and resource infill drilling continued at the Frasers Underground mine with 4,603m drilled and 22 diamond drill holes completed from the Exploration Drive in the second quarter. The drilling confirmed mineralisation extends to the north and north-east of the underground workings and the deposit remains open in both directions.

A further 959m were drilled and 8 diamond drill holes completed from a jump-up rise on the western edge of Panel 2 to test for extensions to the mineralisation in this area. The program is scheduled to be completed in the third quarter.

A previously reported eleven hole drill program was completed during the first quarter to test for projections of mineralisation into the east wall of the Macraes Open Pit. A 24 hole follow-up infill drilling program was completed in the second quarter. Best results include: RCH5531 11m @ 1.86 g/t from 131m, RCH5536 12m @ 3.23 g/t from 166m, and RCH5539 22m @ 1.36 g/t from 179m (Table C).

A separate 22 hole drilling program was completed in June to test for projections of mineralisation into the south wall of the Macraes Open Pit. Results are pending.

Results for both programs will be integrated into a revised Macraes resource estimate which will form the basis of the Life of Mine plan.

The final hole of a three hole (RCD5454, RCD5455 and RCD5545) drill program for 1,565m targeting blind mineralisation located between 2.5 and 3.5 kilometres north of the Macraes Open Pit was completed. Assay results for the final two holes have been returned with encouraging results including an intercept of 16m down hole (15.5m true width) @ 2.07 g/t Au from 242m including 2m down hole (1.9m true width) @ 4.64 g/t Au from 246m in RCD5455 down plunge from Round Hill deposit (Table D and Table E).

A combined surface reverse circulation (RC) and diamond drill program comprising 11 holes for 1,230m has been completed immediately south of the Coronation deposit. Drilling has defined a shallow east dipping 1 to 2 metre thick mineralised hanging-wall shear. Assay results are summarised in Table F. Best results include 3m down hole (2.9m true width) @ 7.94 g/t Au from 136m in hole RCD5464. A 31 RC drill hole infill and extension program (2,920m) has been designed and is expected to commence late in the fourth quarter.

Results quoted in table B are intercepts returning ≥1 gram metres (intercept (m) multiplied by gold grade in grams per ton)

Results quoted in table D are intercepts returning ≥1 gram metres (true width (m) multiplied by gold grade in grams per ton)

Results quoted in table E are intercepts returning ≥1 gram metres (true width (m) multiplied by gold grade in grams per ton)

Results quoted in table F are intercepts returning ≥1 gram metres (true width (m) multiplied by gold grade in grams per ton)

PHILIPPINES

Exploration expenditure in the Philippines for the second quarter of 2012 totalled $0.4 million and $0.7 million for the half year.

Didipio

Exploration continued to focus on the FTAA during the second quarter.  Soil sampling and rock-chips have further defined significant Au-Cu geochemical anomalies in the Upper Tucod (part of TNN prospect), Wangal and Binugawan (part of MMB prospect), D'Beau, and Papaya prospects. Further mapping and sampling is anticipated to advance these prospects to a "drill-ready" with drilling anticipated for the fourth quarter in 2012.

Grid soil sampling continues at Upper Tucod and at Wangal and Binugawan.  A total of 211 soil samples were taken from Upper Tucod and 213 from the MMB area. The soil sampling at Upper Tucod has closed-off the previously defined Au-Cu anomaly at the northern section.  The Au anomaly measures 700m long by about 500m wide with partially coincident Cu. It corresponds to mapped diorite and monzonite porphyry intrusions emplaced within andesitic lavas and volcanic breccia.  The intrusions exhibit weak potassic alteration with secondary biotite and K-spar and rare specks of chalcopyrite. Additional mapping and sampling is anticipated in the third quarter.

At MMB, soil sampling has further defined a N-S trending Au-Cu-As-Mo anomaly that appears to extend from Wangal to Binugawan for a distance of about 3 kilometres. Sampling of stream float returned an assay of 1.0 g/t Au, 659ppm Mo (Molybdenum). Additional mapping and sampling is required to further define this anomaly in anticipation of scout drilling.

An additional 66 soil samples from the Papaya prospect has closed-off the gold anomaly to the NE (within EP-02-07) in advance of drill target definition.   Drilling of the Papaya prospect is anticipated for the fourth quarter of 2012.  Analysis of rock specimens bearing a dark green micaceous mineral (possibly Roscoelite) returned values of 2.77 g/t Au, 71.5 g/t Ag, 1.12% Cu, and 1,742 ppm Vanadium

Exploration of the D'Beau prospect, 1.2 kilometres southeast of Didipio, progressed during the second quarter.  A total of 228 soil samples and 17 rock samples were collected for analysis.  Soil samples delineated a NW-SE Au-Cu anomaly with partly coincident Mo over an area of 500m by 300m consistent with alkali epithermal and/or porphyry-style mineralisation.  To the southwest of this, a circular Au-As anomaly measuring 300m diameter was identified.  Mapping of artisanal adits identified silica-clay-pyrite altered hornblende-andesite and microdiorite dikes with associated pyrite-chalcopyrite-bornite veinlets. Selected rock samples returned assays of up to 3.81 g/t Au and 1.16% Cu.  These mineralised dikes may be explored further by drilling in the fourth quarter of 2012.

Subsequent to quarter end, the Philippines Government released an Executive Order (EO79) in regards to the Philippines mining sector reform. As a result of EO79, the granting of exploration permits is expected to resume and the Company remains in "drill ready" status for some near mine prospects at the Didipio Project and awaits extension of its exploration period of its granted Financial or Technical Assistance Agreement (FTAA).

FINANCIAL SUMMARY

The table below provides selected financial data comparing Q2 2012 with Q1 2012, Q2 2011 and comparing H1 2012 to H1 2011.

* To reflect movements in project creditors as part of Investing Activities, a reclassification from Operating Activities to Investing Activities of $3.3 million was made post Q1

RESULTS OF OPERATIONS

Net Earnings

The Company reported a second quarter net profit of $0.7 million, a major improvement when compared to a net loss of $3.9 million in the first quarter 2012. The result was largely attributable to higher ounces produced and sold, lower overall costs, offset by lower gold prices per ounce received.

Gold production for the second quarter of 2012 was 55,709 ounces, up 10% versus 50,842 ounces in the previous quarter.  This increase was driven by improved production from Macraes Open Pit and Reefton Open Pit mines.

The Company reported EBITDA of $25.6 million in the second quarter compared to $23.3 million in Q1 2012, an increase reflecting the higher production and sale of gold ounces, lower costs of mining and processing offset by lower gold prices per ounce received during the period.

The net result before income tax was a profit of $1.6 million for Q2 2012 compared to a loss of $2.5 million in Q1 2012.

Sales Revenue

Gold revenue in Q2 2012 of $86.7 million is a 2% decrease over Q1 2012 due to lower gold price received more than offsetting the increase in ounces sold.

The average gold price received in the second quarter was $1,613 per ounce compared to $1,708 in the previous quarter. Gold sales volumes for Q2 2012 of 53,756 ounces were 3.7% higher than Q1 2012 (sales of 51,852 ounces).

Operating Costs & Margins

Cash costs per ounce sold were $1,029 for Q2 2012 a decrease of 8.6% compared to Q1 2012 costs of $1,126. This decrease results largely from the higher ounces produced and sold and a weaker New Zealand dollar.

The average cash margin was $584 per ounce for Q2 2012, compared to $582 per ounce in Q1 2012.

Depreciation and Amortisation

Depreciation and amortisation charges include amortisation of mine development, deferred pre-stripping costs and depreciation on equipment.

Depreciation and amortisation charges are calculated on a unit of production basis and totalled $20.0 million for Q2 2012 compared to $21.8 million for Q1 2012.

Net Interest Expense

The net interest expense of $4.0 million for Q2 2012 was in line with that incurred in Q1 2012.

DISCUSSION OF CASH FLOWS

Operating Activities

Cash inflows from operating activities were $20.9 million in Q2 2012 compared to $29.2 million in Q2 2011.  The decrease reflected mainly the decrease in gold ounces sold as well as decreased cash margin per ounce.

Investing Activities

Investing activities comprised expenditure for pre-strip mining and sustaining capital at the New Zealand operations, plus capitalised development costs mainly associated with the construction of the Didipio Project in the Philippines.

Cash used for investing activities totalled $69.3 million compared to $32.0 million in Q2 2011. The expenditure reflects predominantly constructions costs for the Didipio Project of $52.5 million during Q2 2012.

Financing Activities

Financing outflows for Q2 2012 were $4.6 million compared to cash outflows of $3.8 million in Q2 2011. The outflow predominantly represented lease and loan repayments offset by sundry proceeds from capital issues.

DISCUSSION OF FINANCIAL POSITION AND LIQUIDITY

Company's funding and capital requirements

For the quarter ended June 30, 2012, the Company recorded a net profit of $0.7 million. As at that date, cash funds held were $73.1 million. Net current liabilities were $6.3 million at quarter end, after including as a current liability a convertible bond repayment due in December 2012. Subsequent to quarter end, the Company announced that it has secured credit approvals from a group of large multinational banks for a $220 million credit facility to provide for additional liquidity for the repayment of the convertible bonds maturing in December 2012 and December 2013 and a $50 million working capital facility.

Commitments

OceanaGold's capital commitments as at June 30, 2012 are as follows:

This includes equipment for New Zealand operations and contracts supporting the construction of the Didipio Project.

Financial position

Current Assets

As at June 30, 2012 current assets were $142.6 million compared to $190.3 million at the end of the March 31, 2012.  Current assets have decreased by $47.7 million primarily due to a decrease in cash of $50.2 million offset by increases in prepayments.

Non-Current Assets

At June 30, 2012 non-current assets were $717.4 million compared to $657.0 million at March 31, 2012. The increase mainly reflects expenditure of $59.9 million on Property, Plant and Equipment, and Mining Assets resulting from the acquisition of additional equipment (some of which was leased) being greater than depreciation, and further capitalised expenditure in Q2 2012 for the construction of the Didipio Project.

Current Liabilities

Current liabilities increased by $14.9 million in Q2 2012 to $148.9 million compared to $134.0 million in Q1 2012.  This increase is attributable to increased accounts payable for the Didipio Project and New Zealand operations, and renewed insurance premium loan.

Non-Current Liabilities

Non-current liabilities were $221.8 million at June 30, 2012, compared with $220.3 million at March 31, 2012. The slight increase reflects increase in asset retirement and other obligations partly offset by repayment of lease liabilities.

Derivative Assets / Liabilities

For the quarter ended June 30, 2012 the company did not hold any financial derivatives or gold sales contracts.

Shareholders' Equity

A summary of the movement in shareholders' equity is set out below:

Shareholders' equity has decreased by $3.7 million to $489.3 million at June 30, 2012 mainly as a result of currency translation differences reflected in Other Comprehensive Income that arise from the translation of entities with a functional currency other than USD, offset by a net profit for the quarter.

Capital Resources

As at June 30, 2012, the share and securities summary was:

As at July 26, 2012 there was no change in shares and securities:

As at March 31, 2012, the share and securities summary was:

CRITICAL ACCOUNTING ESTIMATES AND ACCOUNTING POLICIES

The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and related notes. The accounting policies that involve significant management judgement and estimates are discussed in this section.  For a list of the significant accounting policies, reference should be made to Note 2 of the December 31, 2011 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 amortised 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 Comprehensive Income.

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 risk-adjusted future cash flows, the timing of those cash flows and the 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 discounted future cash flows from these assets, the assets are written down to the fair value of the estimated future cash flows based on OceanaGold's discount rate for the asset.

Derivative Financial Instruments/Hedge Accounting

The consolidated entity has used 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 the current forward exchange rate for contracts with similar maturity profiles.

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 instalments 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. Deferred tax assets including tax losses are recognised to the extent that it is probable that the company will generate future taxable income. Utilisation of the tax losses also depends on the ability of the entities to satisfy certain tests at the time the losses are recouped.

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.

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Generally, foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than an operation's functional currency are recognised in the statement of income.

ACCOUNTING ESTIMATES

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; possible variations of ore grade or recovery rates; changes in project parameters; 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; general business, economic, competitive, political and social uncertainties 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

Adoption of new accounting policies

No new accounting policies were adopted during the quarter.

Accounting policies effective for future periods

IFRS 9 - "Financial instruments - classification and measurement"
This is the first part of a new standard on classification and measurement of financial assets that will replace IAS 39, Financial Instruments: Recognition and Measurement. IFRS 9 has two Measurement categories: amortised cost and fair value. All equity instruments are measured at fair value.

A debt instrument is at amortised cost only if the entity is holding it to collect contractual cash flows and the cash flows represent principal and interest. Otherwise it is at fair value through profit or loss. Effective for years beginning on/after January 1, 2015.  The group does not have any liabilities designated at fair value so there is no impact expected for reporting.

IFRS 9 - "Financial instruments - classification and measurement"
Updated to include guidance on financial liabilities and de-recognition of financial instruments. Effective for years beginning on/after January 1, 2015. The Company has not assessed the impact of this new standard.

IAS 1 - "Presentation of items of other comprehensive income ("OCI")"
Change to the disclosure in OCI, including a requirement to separate items presented into two groups based on whether or not they may be recycled to profit or loss in the future.  Effective for years beginning on/after July 1, 2012.

IAS 19 - "Employee benefits"
Amended for (i) changes to recognition and measurement of defined benefit pension expense and termination benefits, and (ii) expanded disclosure.  Effective for years beginning on/after January 1, 2013.  Not expected to have a material impact on the Company.

IFRS 13 - "Fair value measurement and disclosure requirements"
Provides a single source of guidance on how to measure fair value and enhances disclosure requirements for fair value measurements. Effective for years beginning on/after January 1, 2013. Not expected to have a material effect on the Company.

"New standards addressing scope of reporting entity"

IFRS 10, - "Consolidated Financial Statements",
IAS 27, - "Consolidated and Separate Financial Statements", and
SIC-12, - "Consolidation - Special Purpose Entities"
IFRS 11, - "Joint Arrangements"
Entities in joint operations will follow accounting for jointly controlled assets and jointly controlled operations under IAS 31.
IFRS 12, - "Disclosure of Interests in Other Entities", Effective for years beginning on/after January 1, 2013.
Not expected to have a material effect on the Company disclosure.

IFRIC 20 - "Stripping costs in the production phase of a surface mine"

Provides guidance on the accounting for overburden (pre-strip) in the production phase.  Costs can only be recognised as an asset if they can be attributed to an identifiable component of the ore body.  Effective January 1, 2013.  Not expected to have a material impact on the Company.

IFRS 7 - "Financial instruments" - disclosures
Amended to enhance disclosure requirements relating to offsetting of financial assets and financial liabilities. Effective for annual periods beginning on/after January 1, 2013. Not expected to affect the accounting of offsetting arrangements or have a material effect on the Company.

IAS 32 - "Financial instruments" - presentation
Amended to clarify requirements for offsetting of financial assets and financial liabilities.  Effective for annual periods beginning on/after January 1, 2014. Not expected to affect the treatment of offsetting arrangements or have a material effect on the Company.

SUMMARY OF QUARTERLY RESULTS OF OPERATIONS

The following table sets forth unaudited information for each of the eight quarters ended September 30, 2010 through to June 30, 2012.  This information has been derived from our unaudited consolidated financial statements which, in the opinion of management, have been prepared on a basis consistent with the audited consolidated financial statements and include all adjustments, consisting only of normal recurring adjustments, necessary for fair presentation of our financial position and results of operations for those periods.  On adoption to IFRS there were no material differences to the income statements and management believes the results are comparable as they were prepared on a consistent basis.

The most significant factors causing variation in the results are the variability in the grade of ore mined from the Macraes and Reefton Open Pit mines 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 revenue and returns.  Adding to the variation are large movements in foreign exchange rates between the USD and the NZD.

NON-GAAP MEASURES

Throughout this document, we have provided measures prepared according to IFRS ("GAAP"), as well as some non-GAAP performance measures. As non-GAAP performance measures do not have a standardised 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 amortisation (EBITDA) is one such non-GAAP measure and a reconciliation of this measure to net earnings/(losses) is provided on page 17.

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 amortisation, 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, 2012.  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, 2012 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, 2012.

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
