Sukhoi Log JORC Table 1
1 Using a gold price assumption of US$1,250/oz
2 The estimates for all deposits are presented on a 100% Polyus ownership basis
3 For the Alluvials, cubic metres (m3) have been converted to tonnages using the general bulk density factor of 1.85 t/m3 strictly for the purpose of the summary accumulations. Gold grades have been adjusted from g/m3 to g/t accordingly. Contained gold estimates are not affected.
4 Any minor discrepancies for sums in the table are related to rounding
5 Using a gold price assumption of US$1,350/oz
6 Using a gold price assumption of US$1,650/oz
