Exploration Target for Wafi-Golpu

The Wafi-Golpu project is located in the Morobe Province of PNG on EL440 approximately 60km southwest of the town of Lae. Wafi-Golpu is a major exploration project that forms part of the Morobe Mining Joint Ventures (MMJV) which is a 50/50 joint venture between Newcrest and Harmony. In July 2011, an updated resource estimate for Wafi-Golpu was reported containing Measured, Indicated and Inferred Mineral Resources for Wafi Golpu totalling approximately 1010 million tonnes containing 26.6 million ounces of gold and 9.0 million tonnes of copper(1). This comprises an extensive body of gold only epithermal style mineralisation (Wafi) located near surface and deeper porphyry related copper+gold mineralisation (Golpu and Nambonga). The Wafi epithermal mineralisation includes oxide, transitional and sulphide ore types with individual ore zones reported at relatively high cut-off grades. Studies show that the resource is quite sensitive to these cut-offs with only minor improvements in margin required to increase the inventory substantially Exploration also demonstrates that these mineralised zones are spatially related to a central diatreme and that the mineralisedinventory substantially. Exploration also demonstrates that these mineralised zones are spatially related to a central diatreme and that the mineralised zones remain open at depth.

In October 2010, an Exploration Target for the Wafi-Golpu project area in excess of 30 million ounces of gold and 8 million tonnes of copper based on a tonnage range between 900 and 1400 million tonnes was reported. This targeted growth of epithermal deposits to between 100 and 200 million tonnes at a grade range between 1.5 and 2.0 grams per tonne plus porphyry deposits to a range of 800 and 1200 million tonnes at grades between 0.7 and 1 1% d 0 5 t 0 9 /t ld1.1% copper and 0.5 to 0.9g/t gold.

Recent work conducted by the MMJV has included a significant amount of additional drilling at Wafi-Golpu, ongoing regional exploration, and detailed concept studies on deposit knowledge and possible development scenarios.

Results from work, including but not limited to very strong gold and copper results from deep drilling at Golpu, demonstrate that the previously g y g g pp p g p p yannounced exploration target for Wafi-Golpu has been achieved and in March 2011 supported revision of the Exploration Target for the Wafi-Golpu project area to in excess of 40 million ounces of gold and 15 million tonnes of copper based on a tonnage range between 1200 and 1700 million tonnes. This targets growth of epithermal deposits to between 100 and 200 million tonnes at a grade range between 1.5 and 2.0 grams per tonne plus porphyry deposits to a range of 1100 and 1500 million tonnes at grades between 0.8 and 1.5% copper and 0.6 to 1.0g/t goldii.

Deep drilling undertaken and reported in recent quarters continues to demonstrate that the Golpu porphyry deposit may be significantly larger than theDeep drilling undertaken and reported in recent quarters continues to demonstrate that the Golpu porphyry deposit may be significantly larger than the reported resource. Results show strongly mineralised porphyry at depth and to the north with grades persisting well into metasediment wall-rocks. Several other porphyry style targets in earlier stages of exploration with encouraging preliminary data also exist in the project area.
