MELBOURNE, Australia, Jan. 19, 2012 /CNW/ - OceanaGold Corporation

Operations

Fourth quarter gold production was up 11% on the previous quarter to 65,750 ounces bringing the total for FY2011 to 252,499 ounces. This was slightly below expectations for the quarter and subsequently the year. Macraes Goldfield fourth quarter production of 44,451 ounces was up 5% compared to the third quarter.  Reefton Goldfield fourth quarter production of 21,299 ounces showed significant improvements when compared to the third quarter with better grade and recoveries, however quarterly production did not meet expectations due to lower ore tonnes mined and processed through the mill. Revenue for the fourth quarter was $106.6 million with the average gold price received during the same period being $1,705 per ounce on 62,515 ounces sold. Operational expenditures for the fourth quarter were $55.6 million (excludes depreciation & amortisation, general & administrative expenses and year end inventory adjustment). Unaudited cash costs were $890 per ounce for the fourth quarter. For the full year 2011, including a year end adjustment for inventory, the unaudited cash costs were $875 per ounce, which is within the guidance range of US$850-$890 per ounce.

Project Development

During the quarter, the Company achieved a number of key milestones with construction of the Didipio Project in Luzon Philippines. These included the commencement of concrete pouring, near completion of the construction accommodation camp, mobilisation by the mining contractor to site and the arrival of the first shipment of structural steel.

Concrete pouring commenced on schedule in November 2011 with good progress made to date with the mill foundations, concentrate storage shed, gold room, concentrate thickener, reagents shed and operations village. Despite heavy rain during the quarter, bulk earthworks for the plant site was completed and excavation progressed reasonably well for the power station. The mining contract was awarded and the contractor commenced mobilising to site in late December.  Mining is scheduled to commence in first quarter 2012.

The construction camp is nearing completion and there are approximately 550 construction contractors and staff on site. All major construction contracts are either awarded or in the process of being tendered.

Didipio Construction expenditure during the quarter was $30.9m and total construction spend since the project recommenced was $65.6m.

During the quarter the Company hosted a site visit where analysts and investors had the opportunity to meet the project team and see the construction progress to date.  In addition, the visitors gained an insight into the strong relationship the Company has developed with the local communities.  The Mayor of Kasibu, the Didipio Barangay Captain and President of the Didipio Community Development Corporation (Dicorp) participated in the site visit.
