Papua New Guinea Mining News and Project Updates
Papua New Guinea's mining sector is anchored by a small number of world-class operations that account for the majority of the country's mineral export revenue. The Lihir gold mine on Lihir Island, operated by Newmont following its acquisition of Newcrest, is one of the world's largest gold deposits and a cornerstone of Papua New Guinea's gold industry.
The Porgera mine in Enga Province has historically been another of PNG's most significant gold producers. Operated through a joint venture involving Barrick Gold and the PNG government, Porgera has navigated complex negotiations over benefit sharing, ownership structure, and environmental management. Ok Tedi in Western Province adds copper and gold output from a large open-pit operation that has been central to PNG's resource economy since the 1980s.
K92 Mining's Kainantu underground gold mine represents a newer generation of PNG mining operations, demonstrating that high-grade underground mining can be successfully developed in the country. Several junior explorers are active across PNG's prospective geological terrains, particularly in the Papuan Fold Belt and along the New Britain volcanic arc.
Discovery Alert monitors Papua New Guinea's mining sector, covering production updates from Lihir, Porgera, and Ok Tedi, exploration news from junior companies, and the policy and political developments that shape one of the Pacific region's most resource-rich mining jurisdictions.
Frequently Asked Questions
What is the largest mining operation in Papua New Guinea?
The Lihir gold mine on Lihir Island is one of Papua New Guinea's largest mining operations and one of the world's largest gold deposits by resource size. The Porgera mine, operated by a joint venture involving Barrick Gold, has historically been another of the country's most significant gold producers. Ok Tedi in Western Province is a major copper and gold mine that has operated since the 1980s.
Is mining good or bad for Papua New Guinea?
Mining has delivered significant economic benefits to Papua New Guinea, contributing a large share of export revenue and government income. However, environmental and social impacts have been contested, particularly around river systems affected by mine waste. Benefit-sharing agreements between mining companies, the national government, and landowner communities remain a central policy challenge for the sector.
How many gold mines are in Papua New Guinea?
Papua New Guinea has several operating gold mines, including Lihir, Porgera, Kainantu, and Hidden Valley. The country also has a number of advanced exploration projects and smaller-scale alluvial gold operations across various provinces. PNG is considered a significant gold-producing nation within the broader Asia-Pacific region, with world-class geological prospectivity attracting ongoing exploration investment.
Who are the major mining companies operating in PNG?
Barrick Gold operates the Porgera mine through a joint venture with the PNG government. Newmont operates the Lihir gold mine following its acquisition of Newcrest. Ok Tedi Mining Limited is owned by a PNG trust structure. K92 Mining operates the Kainantu underground gold mine. Several junior explorers are active across the country's prospective geological terrains.
What copper resources does Papua New Guinea have?
Papua New Guinea holds substantial copper resources, most notably at Ok Tedi in Western Province, which has produced both copper and gold since the 1980s. The Frieda River copper-gold project in Sandaun Province is one of the largest undeveloped copper deposits in the Pacific region. Copper exploration remains active given PNG's prospective geology and global demand for copper in clean energy infrastructure.
