Notes:
1. Mineral Resources include Mineral Reserves.
2. Macraes and Reefton open pit resources constrained by a NZ$2,200/oz gold price pit shell. Macraes underground resources are geologically constrained.
3. The commencement of Reefton closure and rehabilitation was announced on 19 December 2016.
4. The Waihi open pit resources are reported to a 0.5 g/t Au cut-off within a pit design to the 890mRL. The underground resources are based on a NZ$1,857/oz gold price.
5. For Didipio, open pit resources are reported above the 2,460mRL and underground resources between the 2,460mRL and 2,070mRL. Open pit resources use AuEq cut-off based on US$1,300/oz gold and US$3.00/lb copper. Underground resources use AuEq cut-off based on
US$1,450/oz gold and US$3.80/lb copper
6. Haile open pit resources are reported to a 0.41 g/t Au cut-off within a US$1,200/oz gold price pit shell
