About Didipio
The Didipio area was first recognized as a gold province in the 1970s when alluvial gold deposits were discovered in the region. We acquired the Didipio project in 2006 as part of a merger with Climax Mining and subsequently built the mine, bringing it into commercial production in 2013. Didipio operated as an open pit until it transitioned to an underground mine in 2018.
Today, we blend ore stockpiled from the open pit phase with ore from the underground and are assessing the opportunity to increase underground mining rates to 2.5 million tonnes per annum. Didipio employs approximately 850 people, many of whom are from the local region.
