Mick Wilkes, Managing Director and CEO commented, "We are extremely pleased to formally announce the declaration of commercial production at Didipio with an effective date of 1 April 2013. This marks the official start to a very important chapter for OceanaGold as we transition into a multinational gold producer. Since construction commenced in June 2011, the OceanaGold team has worked hard to deliver on its commitments to our stakeholders over the past 22 months and on behalf of the Board of Directors, I would like to thank our OceanaGold team members for their tireless commitment to making this mine a reality. We have successfully progressed from first ore in the mills to commercial production in just over three months which is a great accomplishment and a testament to the skill of the construction and commissioning teams resulting in the seamless transition to our equally talented operations team. To date, more than 22,000 tonnes of copper gold concentrate has already been produced. I'd also like to personally acknowledge our government and community partners for their ongoing support and contributions towards this achievement."
