1 any minor discrepancies for sums in the table are related to rounding.
2 gold price assumptions:
- US$1,350/oz for those deposits where new mining studies were conducted during 2020 (Blagodatnoye, Kuranakh, Verninskoye, Sukhoi Log, and Panimba).
- US$1,250/oz for Olimpiada, Titimukhta, Natalka, Alluvials, and Chertovo Koryto.
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 the estimates for all deposits are presented on a 100% ownership basis.
5 any minor discrepancies for sums in the table are related to rounding.
6 Gold price assumptions:
- US$1,650/oz for deposits with new resource models in 2020 (Verninskoye, Blagodatnoye, Kuranakh, Sukhoi Log, Panimba, and Razdolinskoye)
- US$1,500/oz for Olimpiada, Natalka, Chertovo Koryto. Bamskoye, Medvezhy
7for 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.
8Measured, Indicated and Inferred Mineral Resources 2020 estimate for Razdolinskoye includes estimates for Svetloye, Zmeinoye, Antoninovskoye, and Poputninskoye deposits.
