Ore Reserves, Mineral Resources and Exploration update as at 1 January 2019

Polymetal International plc announces its exploration update for the year ended 31 December 2018, and reports its Ore Reserves and Mineral Resources as at 1 January 2019 in accordance with the JORC Code (2012)¹.

“In 2018, Polymetal significantly expanded its mineral inventory on the back of a twofold increase in Ore Reserves at Nezhda, a 5-year life-of-mine extension at Mayskoye and confirmation of a world-class resource at Prognoz”, – said Vitaly Nesis, Group CEO of Polymetal, commenting on the results. “In 2019 we will continue to focus on extending the life-of-mine at producing assets”.

2018 HIGHLIGHTS

• Group Ore Reserves increased by 15% year-on-year and are now estimated at 24.0 Moz of gold equivalent (GE). The main drivers were the successful resource-to-reserve conversion at Mayskoye and the completion of a revised estimate at Nezhda following the Company’s consolidation of 100% ownership in the property. The share of gold in Ore Reserves increased to 93%.

• Mineral Resources (in addition to Ore Reserves) grew 44% year-on-year to 26.3 Moz of GE on the back of an initial Mineral Resource estimate at Prognoz and Bolshevik (Kyzyl), as well as the revised estimate at Nezhda. The share of gold in Mineral Resources stands at 80%, silver at 17%.

• The average grade in Ore Reserves remained largely unchanged over the previous year at 3.8 g/t of GE and remains one of the highest in the sector. The average grade in Mineral Resources increased 8% to 5.1 g/t of GE on the back of high-grade additions at Nezhda and Prognoz.

• In 2018, the Company continued to use conservative price assumptions of US$ 1,200/oz for gold and lowered the silver price from US$ 16/oz to US$ 15/oz.

• GE Ore Reserves per share grew 6% year-on-year.

• Polymetal completed 350 km of exploration drilling in 2018.
