Polymetal International plc (POLY) Polymetal: Ore Reserves increase at Kyzyl 09-Nov-2020 / 10:00 MSK Dissemination of a Regulatory Announcement, transmitted by EQS Group. The issuer is solely responsible for the content of this announcement. Release time IMMEDIATE  LSE, MOEX, AIX: POLY / ADR: AUCOY Date 09 November 2020 Polymetal International plc Ore Reserves increase at Kyzyl Polymetal announces a 25% increase in Ore Reserves at Kyzyl to 10.3 Moz of gold following initial reserve estimate at East Bakyrchik of 2.2 Moz of gold. "A substantial reserve addition at East Bakyrchik extends the life-of-mine at Kyzyl to 30 years", said Vitaly Nesis, Group CEO of Polymetal. "Importantly, open-pit mining will now continue till 2036". HIGHLIGHTS The initial JORC-compliant Ore Reserve estimate for East Bakyrchik (Zone 2 of Kyzyl) as at 1 April 2020 comprises 18.8 Mt of ore at an average grade of 3.7 g/t containing 2.2 Moz of gold, roughly 80% of which are underground. Total Kyzyl Ore Reserves now stand at 59.3 Mt of ore with an average grade of 5.4 g/t containing 10.3 Moz of gold. This represents a 25% increase compared with the estimate at the end of 2019. Open-pit reserves increased by 9% to 4.3 Moz of gold contained at an average grade of 4.9 g/t, underground reserves were up 40% to 6.0 Moz at an average grade of 5.8 g/t. East Bakyrchik has added 5 years to the total Kyzyl life of mine (2050), while life-of-mine (LOM) for the open pit has extended by 6 years (to 2036). East Bakyrchik open-pit LOM average strip ratio is 27 t/t. The new mining schedule assumes an increase in the capacity of the Kyzyl processing plant from 2.0 Mtpa to 2.2 Mtpa in 2022. East Bakyrchik Ore Reserve estimate incorporates data from the exploration campaign in 2015-2020 including 29.9 km of drilling (168 diamond drill holes). Total Kyzyl Mineral Resources (additional to Ore Reserves) amount to 15.6 Mt of ore with an average grade of 4.0 g/t representing 2.0 Moz of gold contained.

For the Bakyrchik open pit and underground the previous estimate was performed as at 1 July 2019, the updated estimate was prepared as at 1 April 2020 and accounts for the pit extension and depletion. A cut-off grade of 0.8 g/t of gold was applied for the open pit and 3.0 g/t for the underground. East Bakyrchik initial Ore Reserve estimate was performed as at 1 April 2020. A cut-off grade for recovered gold of 0.6 g/t was applied for the open pit and 2.0 g/t for the underground, the reserves were estimated on the basis of variable recovery value for each of the blocks generated.
