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."HIGHLIGHTSProduction of first copper-gold concentrate at DidipioFlotation plant including filter, commissioned and performing to expectationsCommenced commissioning of gravity gold circuit2013 guidance 285 - 325koz Au @ US$650 - US$800/oz (net of copper by-product credits)Didipio Project Construction & Commissioning ProgressThe main process plant construction activities are complete with remaining punch list items to be completed concurrently with operations.
