Unkur Cu-Ag project in Udokan mining district, Zabaikalie, Russia

Azarga Metals owns 100% of the Unkur Copper-Silver Project in the Zabaikalsky Region, Russia. On completion of 2016-2018 exploration program, the Company estimated an Inferred Resource of 62 million tonnes at 0.53% Cu and 38.6g/t Ag. In 2019-2020, Azarga has doubled the strike length of mineralized envelope to a total of 6.5 km, which remains open in both directions along strike and down-dip. While the new resource estimate study is ongoing, the Company received results of a metallurgy test showing recoveries for sulphide material up to 89.1% Cu and 82.7% Ag into commercially attractive ~30% Cu and ~2,000 g/t Ag concentrate. Oxide material yielded recoveries up to 96.4% Cu with acid leach and 96.7% Ag recoveries with cyanide leach.
