About Lihir

Our Lihir Operation, located on the beautiful island of Niolam, approximately 800km north of Papua New Guinea's capital, Port Moresby, is one of the world’s largest gold mines. Set within a geothermically active, extinct volcanic crater, Lihir operates an open-pit mine producing refractory ore, which undergoes pressure oxidation and conventional leaching to recover gold. Our workforce includes both residential and commute rosters, creating a diverse and dynamic team. Lihir offers a range of recreational facilities, including a gym, sports club, restaurant, bar, swimming pool, tennis and squash courts, and a 9-hole golf course. For those who enjoy the outdoors, the Lihir fishing and boating clubs provide access to pristine waters and beaches, while our onsite deli and café serve fresh local and imported produce, barista-made coffee, and freshly baked goods.

We are proud to work closely with the local Lihirian community and value its vibrant culture. Through initiatives like our School to Mine program, we offer meaningful employment, training, and development opportunities for Lihirian men and women, as well as scholarships and vocational apprenticeships. We also partner with the New Ireland Province to ensure economic benefits flow directly to the community, strengthening our commitment to sustainable development and positive local impact.
