Polymetal International plc (POLY) Polymetal: Ore Reserves, Mineral Resources and Exploration update as at 1 January 2023 01-March-2023 / 10:00 MSK The issuer is solely responsible for the content of this announcement. Release time IMMEDIATE  LSE, MOEX, AIX: POLY ADR: AUCOY Date 1 March 2023 Polymetal International plc Ore Reserves, Mineral Resources and Exploration update as at 1 January 2023 Polymetal International plc (“Polymetal”, the “Company” or the “Group”) announces its Ore Reserves and Mineral Resources as at 1 January 2023, in accordance with the JORC Code (2012) and exploration update for the year ended 31 December 2022. “Polymetal did not replace its ore depletion and recorded declining ore reserves in 2022. The exploration season was severely affected by the indirect impact of sanctions placed on, amongst other things, imports of diamond drilling spares and materials into Russia. We remain confident in the Group’s ability to grow our high-quality reserve base and expect the resumption of the upward trend in 2023”, said Vitaly Nesis, Group CEO of Polymetal HIGHLIGHTS In 2022, Group Ore Reserves (“OR”) decreased by 9% year-on-year (y-o-y) to 27.3 Moz of gold equivalent (GE)[1], mostly due to mining depletion. This was partially offset by the successful exploration results at Omolon hub (Burgali and Nevenrekan), Pesherny (Voro hub), as well as initial reserve estimates at Galka and Tamunier (Voro hub). The average grade in OR increased by 5% y-o-y and stood at 3.6 g/t of GE. Average mine-life stands at 13 years. Share of OR for open-pit mining remained unchanged versus previous year at 52%. Share of refractory reserves grew by 3 p.p. y-o-y to 74%. Mineral Resources (additional to Ore Reserves) (“MR”) grew by 5% y-o-y to 25.8 Moz of GE due to positive revaluation at Kyzyl, Omolon, and Nezhda, as well as initial resource estimates at Kegali and Tumanin (Omolon hub). The average GE grade in MR was up by 10% y-o-y to 4.5 g/t. 2023 OUTLOOK In 2023, Polymetal will continue to invest in both near-mine and greenfield exploration projects. The key objectives are: Re-evaluate Ore Reserves at Kyzyl. Prepare an initial Ore Reserve estimate at Talgiy (Albazino). Prepare an initial Ore Reserve estimate at Pavlov (Voro hub). [1]) GE includes gold and silver, unless otherwise stated. Base metals are excluded due to their immateriality.

EXPLORATION RESULTS Exploration areas and volumes (mine site exploration excluded) (1) Drilling, km 2022 2021 Russia (2) 223.1 339.6 Kazakhstan (2) 91.1 41.9 Total 314.2 381.5 Discrepancies in calculations are due to rounding. Including JVs with more than 50% share owned by Polymetal. In 2022, 314.2 km (including JVs) of exploration drilling was completed. As a result of the imposed sanctions on Russia, import of drilling spare parts and materials was restricted, leading to a substantial decrease in drilling activities. Furthermore, as a part of budget optimisation, JV grassroots exploration in Russia was reduced, contributing to overall drop in drilling volumes.
