The Lihir operation on Niolam Island in the New Ireland Province of Papua New Guinea (PNG), 900 kilometres north-east of Port Moresby, is 100 per cent owned and operated by Lihir Gold Limited (LGL).
Newcrest acquired the Lihir operation as a result of the merger with LGL by court-approved scheme of arrangement in August 2010.
The gold deposit at Lihir is within the Luise Caldera, an extinct volcanic crater that is geothermally active, and is one of the largest known gold deposits in the world. Most of the ore is refractory and is treated using pressure oxidation before the gold is recovered by a conventional leach process. Lihir produces gold doré.
During the June 2013 financial year, Lihir produced 649,340 ounces of gold. Since production commenced in 1997, the site has produced more than 9 million ounces of gold.
