The Panguna mine, discovered in the late 1960s, contains at least 5-6 billion tons of ore and over 20 million ounces of gold. After its closure nearly 40 years ago due to local protests and severe environmental issues, the mine's reopening is being considered, potentially requiring $6 billion in investment.
Analysts project production of up to 350,000 tons of copper annually, positioning it as a leading facility in the Indo-Pacific region, second only to Grasberg. Environmental sustainability is critical for local authorities, given the mine's historical pollution that fueled conflict. The decision on resuming operations is expected in Q3 2026, with Indian firm Lloyds Metals and Energy currently favored for the project.
