**Notes:**
- Mineral Resources are reported inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
- All resources are based on the following assumptions: metal prices of US$2,450/oz gold, US$4.50/lb copper and US$28.50/oz silver; NZD/USD exchange rate of 0.60.
- Macraes Open Pit resources are constrained by optimised shells based upon economic assumptions above. Waihi Open Pit resources reported within a pit design limited by infrastructural considerations. Haile Open Pit resources reported within the reserve design pit.
- Underground resources are reported within volumes guided by conceptual stope designs which are based upon economic assumptions above and exclude dilution.
- Mineral Resources are reported on a 100% basis. OceanaGold holds an 80% attributable interest in the Didipio Mine.

**Haile:**
- Open Pit primary cut-off grade is 0.50 g/​t Au, while oxide cut-off grade is 0.60 g/​t Au. Horseshoe, Ledbetter and Palomino underground resources at 1.70 g/​t Au cut-off.

**Didipio:**
- 13.2 Mt surface stockpile inventory based on mining cut-off grades at the time ranging from 0.27 g/​t to 0.40 AuEq.
- Underground resources reported at a cut-off grade of 0.67 g/​t AuEq between the 2,460mRL and 1,800mRL with AuEq cut-off grade based on presented gold and copper prices. AuEq = Au g/​t + 1.27 x Cu %.

**Macraes:**
- Open Pits cut-off grades between 0.25 g/​t Au and 0.40 g/​t Au.
- Golden Point underground cut-off grade is 0.97 g/​t Au.

**Waihi:**
- Martha underground cut-off grade is 2.15 g/​t Au, Wharekirauponga cut-off grade is 1.70 g/​t Au.
- Martha Open Pit cut-off grade is 0.5 g/​t Au and Gladstone Open Pit cut-off grade is 0.56 g/​t Au.

Haile is the largest gold mine in the eastern United States and is our largest producing asset.\\\n\\\nGold was first discovered at Haile in 1827, with the site seeing intermittent production over the decades. We acquired Haile through the acquisition of Romarco Minerals in 2015 and commenced commercial production in early 2017. Since then, Haile has produced over 1.4 Moz of gold* and it is expected to be a key driver of our production growth.

We acquired the Didipio project in 2006 as part of a merger with Climax Mining and subsequently built the mine, bringing it into commercial production in 2013. Didipio operated as an open pit until it transitioned to an underground mine in 2018.\\\n\\\nToday, we blend ore stockpiled from the open pit phase with ore from the underground and are assessing the opportunity to increase underground mining rates.
