INVESTOR SITE VISIT

Lihir Gold Limited hosted a visit by investors and analysts to its operations at Lihir Island in Papua New Guinea this week. The visit was aimed at providing increased understanding of Lihir’s operations and demonstrating the progress made on initiatives to improve reliability and efficiency.

Highlights from the site visit and presentations (attached) are:

• Increased operational robustness underpins confidence that the 600,000 ounces production target will be achieved in 2004.

• Waste stripping operations in Lienetz are progressing well. This activity, particularly until the end of Q1 2005, is important for 2005 production levels with small, high grade Lienetz benches currently scheduled to be accessed at the end of the year.

• The upgraded carbon regeneration kiln, expected to progressively raise recovery levels from November, has been commissioned. Gravity separation, to capture free gold, is to be employed to further boost recoveries during 2005.

• Construction activity on the 30MW geothermal power generation facility, being built to substantially reduce site energy costs, is proceeding according to plan and on track for commissioning in Q2 of 2005. Work investigating a further 20MW is being fast-tracked for a decision as early as possible, likely in Q1 of 2005.

• Capital expenditure requirements remains in line with previous guidance.

• A detailed bottom-up review of costs is ongoing and initiatives are being progressively implemented.

• Investigation of a potential expansion of processing capacity by the addition of a flotation plant is proceeding with encouraging results. The status of the study and potential benefits were outlined during the visit. This work is due to be completed in March.
