K18 billion Wafi-Golpu Mining project to start in Papua New Guinea The Papua New Guinea is expected to see a windfall of over K18 billion investment in its economy as the construction phase of the Wafi-Golpu copper and gold project in Morobe, is set to begin after the country's Government granted it an environment permit, the National Reports. The project's construction phase alone, to be undertaken by the developers Harmony Gold Mining Company Limited and Newcrest Mining Limited, is expected to cost K17.26 million. “At this time when our economy is contracting, it is important that we must bring in a major project to (be a catalyst to) reviving the economy,” said Environment, Conservation and Climate Change Minister Wera Mori.
