PJSC Polyus (MOEX — PLZL), the largest gold producer in Russia, announces the results of the review of the Company’s Ore Reserves and Mineral Resources as at 31 December 2016 in accordance with the JORC Code 2012.

Polyus’ Proved and Probable (P&P) Ore Reservesequate to 71 moz of gold andits Measured, Indicated and Inferred (MI&I) Mineral Resources standat 193 moz. Correspondingly, Polyus ranks second by attributable gold reserves (after Barrick Gold) and third by attributable gold resources (after AngloGold and Barrick Gold) among the world’s largest gold mining companies.

A maiden estimate of the JORC Mineral Resources for Sukhoi Log has been made at 58 moz and included in the Group figures. The ore reserves at the asset have not yet been estimated.

The following data has been drawn from the June 2017 Competent Person’s Report (CPR), on the Mineral Assets of Polyus, as prepared by AMC Consultants Pty Ltd (AMC).

Ore Reserves Highlights

  • Polyus’ Ore Reserves amounted to 71 moz of gold.

    • The Krasnoyarsk Business Unit has the largest share of the Company’s reserves, with 30 moz of Ore Reserves reported at Olimpiada and 10 moz at Blagodatnoye.
    • Ore Reserves at Verninskoye and Kuranakhwere recorded at 5.3 moz and 4.5 moz, respectively.
  • Natalka, Polyus’ main greenfield project, has estimated Ore Reserves of 16 moz.
  • Sukhoi Log’s Ore Reserves have not yet been estimated and the Company expects these to be included in its reserve statement before the end of 2019. The asset was acquired in February 2017 and additional exploration work has started.
  • Whilst the average Ore Reserve grade is estimated at 1.8 g/t, it stands at 2.0 g/t when excluding estimates for Alluvial operations and lower grade ore for heap leaching operations at Kuranakh and Blagodatnoye.

Mineral Resources Highlights

  • The Company’s Mineral Resources stand at 193 moz largely reflecting the inclusion of 58 moz of Inferred Mineral Resources for Sukhoi Log2.
  • Almost 50% of the Company’s Mineral Resources are attributable to operational mines:
    • Olimpiada’s Mineral Resources are estimated at 46 moz.
    • Blagodatnoye’s Mineral Resources stand at 19 moz.
    • Verninskoe and Kuranakh’s Mineral Resources include estimates of 12 moz and 9.2 moz, respectively.
  • Natalka Mineral Resources amount to 34 moz.
  • First mineral resources estimates for Sukhoi Log indicate the deposit contains 58 mozof gold grading 2.0 g/t. This corresponds to the latest available Russian standards GKZ (C1+C2) estimate of 62.8 moz grading 2.1 g/t.
