Notes to Ore Reserves and Mineral Resources table:
- Rounding of figures causes some numbers to not add correctly.
- Nueva Esperanza metallurgical recoveries: 80% Au and 84% Ag estimated from test work by Kingsgate.
- Chatree metallurgical recoveries: 83.3% Au and 38.7% Ag based on metallurgical test work and plant performance.
- Cut-off grades for Resources are: Chatree 0.30 g/t Au, Nueva Esperanza 0.5g/t AuEq60 (assuming metal prices of USD1,200/oz Au, USD19.00/oz Ag and metallurgical recoveries as per (2) above.
- Nueva Esperanza Ore Reserves are based on a floating cut-off grade method. In this method each Resource block is subjected to a series of estimates to generate revenue and cost fields that are used to determine a breakeven cut-off grade.
- Please refer to ASX:KCN release published 14 April 2016 titled, “Nueva Esperanza Pre-Feasibility Study Confirms Kingsgate Growth Strategy” for details on Mineral Resources, Ore Reserves and JORC 2012 Table 1.
Chatree Ore Reserves (Assuming Metallurgical Licence Granted)
The table below shows what the Chatree Reserve would be if the Metallurgical Licence was granted in the future.

Notes:
-
- For the material in the table above to become a JORC 2012 Ore Reserve, the Thai Department of Primary Industries and Mines would need to grant the Chatree Gold Mine a Metallurgical Licence.
- The information in the table above is not currently an Ore Reserve under JORC reporting requirements.
