OceanaGold Announces First Concentrate Produced at Didipio and Provides FY2013 
Production Guidance 
MELBOURNE, Dec. 18, 2012 /CNW/ - OceanaGold Corporation (ASX: OGC, TSX: OGC, 
NZX: OGC) (the "Company") is pleased to announce that first copper-gold 
concentrate has been produced at the Didipio Project in the Philippines as 
commissioning of the process plant continues to track to expectations. 
Mick Wilkes, Managing Director & CEO stated, "Following the start of milling 
activities late in November, commissioning has advanced well. Over the past 
week we have successfully commissioned the flotation cells and filter to 
produce saleable copper-gold concentrate. The process plant is now running in 
steady-state and the remainder of commissioning activities this year will 
focus on increasing throughput and improving recoveries and concentrate grade. 
This is a great outcome for the Company, the local communities of Nueva 
Viscaya and Quirino provinces and for the Republic of the Philippines. I would 
also like to acknowledge the support for the project we have received from our 
national and local government partners and we look forward to further 
strengthening this relationship in the future." 
He went on to say "We have had a strong finish to the year as expected with 
production from New Zealand on track to meet the revised guidance. We expect 
strong production next year in New Zealand and with Didipio coming on stream 
as planned. We are in a great position heading into 2013."

    --  Commenced commissioning of gravity gold circuit

Didipio Project Construction & Commissioning Progress

The main process plant construction activities are complete with remaining 
punch list items to be completed concurrently with operations. Construction of 
the remaining infrastructure such as plant and mine maintenance workshops will 
be completed as part of next year's capital works, in conjunction with the 
ramp up of the process plant.

Commissioning has progressed well through the flotation and filtration stages 
of the plant, with the production of on-specification copper-gold concentrate 
filter cake. Commissioning of the gravity circuit is currently underway.

Milling rates currently are higher than predicted for this stage of the 
commissioning cycle, and the focus is on achieving recovery to maximise 
concentrate production.

FY2013 Production Guidance

The Company is also pleased to provide production guidance for FY2013 of 
285,000 - 325,000 oz of gold at cash costs of US$650-$800/oz net of copper 
by-product credits. Copper production from Didipio is expected to be in the 
range of 15 kt to 18 kt of copper in concentrate. During the commissioning 
phase, costs of production, offset by any revenue received will be capitalised 
in the balance sheet. The exact timing of revenue and costs reporting to the 
income statement is currently unknown but expected to be around the end of the 
first quarter next year. The Company will provide an updated cash cost range 
at that time.
