Notes:
1. The open pit Mineral Resource is reported at a 0.3g/t Au cut-off for oxide material and a 0.4g/t Au cut-off for transitional and fresh material,
constrained within an a US$1,400/oz Au (A$1,817/oz Au) optimised pit shell based on actual mining and processing costs.
2. The underground Mineral Resource is reported outside the US$1,400/oz Au pit optimisation based on underground mineable shapes at a
cut-off grade of 2.0g/t Au.
3. All figures are rounded to reflect appropriate levels of confidence. Apparent differences may occur due to rounding.
4. Mineral Resources are inclusive of Ore Reserves.
5. All Mineral Resources are completed in accordance with the 2012 JORC Code.
6. JORC Code (2012) Table 1 Parameters are contained within IGO’s 2016 ASX Resources and Reserves Statement as released to the ASX which

Notes:
1. The Proven and Probable Ore Reserves is reported above economic break-even gold cut-off grade for each material type at nominated gold
price of US$1,100/oz (A$1,436/oz).
2. The Ore Reserve estimate is update based on depletion as at 30th June 2016, using the Resource model from July 2015.
3. The cut-off grades reported were 0.6/g Au for oxide material and 0.7g/t Au for transitional and fresh.
4. All figures are rounded to reflect appropriate levels of confidence. Apparent differences may occur due to rounding.
