Ore Reserves, Mineral Resources and Exploration update as at 1 January 2020
Polymetal International plc announces its Ore Reserves and Mineral Resources as at 1 January 2020 in
accordance with the JORC Code (2012) 1 1 and exploration update for the year ended 31 December 2019.
"Significant growth in Ore Reserves at Kyzyl and a two-fold increase in reserves at Veduga were the key
drivers behind the Group's Ore Reserves extension", said Vitaly Nesis, Group CEO of Polymetal. "In
2020, we will focus on reserves and resources updates at some of our key development projects and will
continue exploration activities to extend the life of existing mines".
2019 HIGHLIGHTS
• Group Ore Reserves increased by 5% year-on-year to 25.2 Moz of gold equivalent (GE) due to
successful exploration results with the subsequent re-evaluation of Ore Reserves at Kyzyl, Veduga,
Kutyn and initial estimate at Primorskoye (Dukat hub). GE Ore Reserves per share also grew by 5%.
• Mineral Resources (additional to Ore Reserves) declined by 4% year-on-year to 25.4 Moz of GE. The
Lichkvaz disposal and conversion of Mineral Resources to Ore Reserves at Kyzyl, Primorskoye and
Veduga were largely compensated by initial Mineral Resources estimate of Elevator (Varvara hub) and
increase of resources at Albazino and Svetloye.
• The average grade in Ore Reserves remained largely unchanged over the previous year at 3.7 g/t of
GE. It continues to be one of the highest within the sector globally. The average Mineral Resources
grade also remained stable at 5.2 g/t of GE.
• In 2019, the Company maintained conservative price assumptions for both Ore Reserve and Mineral
Resource estimates at US$ 1,200/oz for gold and US$ 15/oz for silver.
• Polymetal completed 198 km of exploration drilling in 2019. Drilling expenses amounted to US$ 18.1
million.

EXPLORATION RESULTS
In 2019, exploration was focused on areas in close proximity to the Company's existing assets.
Exploration activities were carried out at 52 licensed properties. 13 new licenses were obtained for
geological studies, exploration and production of gold, silver, PGMs and copper. In total, 198 km of
drilling was completed.
Kyzyl
• The updated Ore Reserve and Mineral Resources estimate for Bakyrchik conducted in 2019 incorporates
data from additional 239 diamond drill holes, 41.5 km of drilling, which resulted in the extension
of mineralization zones within the existing ore bodies and update of the resource model. According
to the updated estimate, open-pit reserves now equal to 3.9 Moz of gold with an average grade of
5.6 g/t. Underground reserves increased to 4.3 Moz with an average grade of 7.1 g/t. Additional
Mineral Resources declined by 374 Koz to 3.5 Moz with an average grade of 5.4 g/t due to conversion
to Ore Reserves. Life of open-pit increased from 10 years to 14 years.
• In 2019, Polymetal continued exploration drilling at Kyzyl's second ore zone, East Bakyrchik
(Promezhutochniy and Glubokiy Log sections), to study the possibility of the open-pit expansion. 24
drill holes totaling 5.3 km of drilling were completed resulting in clarification of ore bodies'
contours and the mineralization boundaries.
• In 2020, the Company plans to update Ore Reserve and Mineral Resource estimate to include the
results of East Bakyrchik evaluation.
Albazino
• In 2019, exploration activities were focused on additional prospecting of the Mineral Resources at
Ekaterina 2 mine. Additional Mineral Resources increased by 159 Koz to 1.8 Moz GE with an average
grade of 4.6 g/t
• Exploration was carried out at the Talgiy section of the Urkachik area (47 thousand m3 of trenches,
4.7 km of drilling). In 2020, Polymetal plans to continue exploration drilling at Talgiy in order
to prepare initial Mineral Resource estimate. Additional resources are expected to be established
on the flanks of the deposit due to the identification of new ore bodies and evaluation of new
prospective areas (Pikhtovy site).
Varvara hub
• At Elevator, 4.8 km of drilling was completed, aiming to explore primary gold ore for open-pit
mining. Based on exploration activity in 2019 and previous years, an initial Mineral Resource
estimate was prepared. Resources amounted to 402 Koz of gold with an average grade of 1.8 g/t.
Inclusion of Elevator's resources offset the decrease in resources at Varvara and Komar
attributable to changes in the boundaries of the Mineral Resources. Total hub's additional Mineral
Resources decreased by 150 Koz to 1.5 Moz of GE.
• At Vostochno-Tarutinsky gold-copper deposit, 28.3 km were drilled, including 21.7 km of exploration
drilling, in order to prepare an initial Mineral Resource estimate.
• In 2020, the Company plans to continue exploration on the flanks of the Elevator deposit aiming to
upgrade the categories of Mineral Resources and convert them into Ore Reserves.
Voro hub
• Additional Mineral Resources of Voro hub remained mostly unchanged over the previous year at 1.3
Moz of GE with an average grade of 4.9 g/t.
• At Voro, a total of 10.5 km of exploration drilling was completed in 2019 to estimate underground
mineral resources on the northern flank and to estimate mineral resources of the oxidized ores for
open-pit mining on the western flank.
• At Pescherny, 12.4 km was drilled. Technological studies and a set of field and laboratory
hydrogeological and engineering-geological studies were completed.
• In 2020, Polymetal plans to prepare an initial Ore Reserve and the updated Mineral Resource
estimate of Pescherny deposit, as well as to complete exploration of the underground resources at
Voro deposit and to continue exploration in its surrounding area.
Omolon hub
• 5.6 km of exploration drilling was completed at the Nevenrekan deposit to close the ore bodies
along the strike at zone 1 and assess their extension. Mineral Resources increased by 78 Koz to 242
Koz of GE with an average grade of 19.3 g/t.
Svetloye hub
• In 2019, exploration was carried out on the remote flanks of Svetloye deposit. An increase in
additional Mineral Resources of 109 Koz at Emmy and Lyudmila ore zones was obtained due to an
improvement in the quality of the ore and wider ore bodies.
• In 2020, the Company plans to continue exploration drilling and trenching on the flanks of Emmy and
Lyudmila ore zones aiming to further increase mineral resources base.
Dukat hub
• According to the initial estimate, Ore Reserves of Primorskoye deposit amounted to 12.2 Moz silver
equivalent with an average grade of 3,113 g/t at a cut-off grade of 1,115 g/t of silver equivalent
(for processing at Lunnoye plant). Additional Mineral Resources as a result of the conversion
decreased by 20.3 Moz in silver equivalent.
Nezhda
• In 2019, exploration activities were focused on the southern flanks of the Nezhda deposit.
According to the preliminary estimates, an increase in the open-pit Mineral Resources is possible.
• In 2020, Polymetal plans to continue exploration activities on the flanks of the deposit to
identify new mineralized zones and update the mineralization estimates of the known ore bodies.
Prognoz
• In 2019, the Company conducted 41.4 km of drilling, including 31.1 km of exploration drilling, 5.3
km of geotechnical drilling for plant construction, 2.5 km of hydrogeological drilling and 2.4 km
of technological drilling.
• In 2020, Polymetal plans to prepare an initial Ore Reserve and an updated Mineral Resource
estimates of Prognoz deposit as well as to carry additional exploration activity out on the flanks
and surrounding areas of the deposit.
Veduga
• In 2019, the Company prepared an updated Mineral Resource and Ore Reserve estimate based on
exploration activities conducted in 2017-2018. As at 01.01.2020, the deposit's Ore Reserves 2 2
totaled 2.7 Moz of gold with an average grade of 4.5 g/t, which is 1.4 Moz more than in the
previous evaluation. Additional Mineral Resources halved to 200 Koz due to conversion to Ore
Reserves.
• In 2019, the Company carried out 19.2 km of exploration drilling at the deeper levels of the known
ore bodies.
• In 2020, Polymetal plans to evaluate the potential ore body 1 to a horizon of -650 m and also
continue to identify new resources at the Strelka ore zone. The Company expects to achieve an
increase of at least 1 Moz of gold in Mineral Resources as a result of this exploration campaign.
Kutyn
• In 2019, 16.1 km of exploration drilling and 56.9 thousand m3 of trenches were completed at Kutyn.
Based on the results of drilling conducted in 2017-2019, an updated geological model and Mineral
Resource and Ore Reserve estimate were prepared.
• Ore Reserves increased by 425 Koz compared to the previous estimate and amounted to 812 Koz of gold
with an average grade of 3.0 g/t. Mineral Resources totaled 785 Koz with an average grade of 3.7
g/t.
• In 2020, additional exploration and evaluation work will be carried out on the flanks of the
explored ore zones to verify new promising areas. Detailed drilling will be performed in the main
ore zones within the expected open-pit oxidized boundaries to convert Mineral Resources into Ore
Reserves.
PGMs
• Exploration drilling was carried out at Kenti and Shargi ore zones at the Viksha PGM deposit in
Karelia aiming to upgrade the Mineral Resources categories. The resource model of the Viksha
deposit was updated, reflecting changing metal prices as well. As a result, total Mineral Resources
decreased to 5.7 Moz of PdEq, while the share of Measured and Indicated Resources increased from
13% to 65%.
• In 2020, exploration activities are set to continue at the flanks of the Kenti and Shargi ore zones
with a view to upgrade the resources of the deposit.

1. Mineral Resources are reported in accordance with the JORC Code (2012). Estimate prepared by
Polymetal as at 05.09.2019. Price for Pd = US$1,500/oz, Pt = US$800/oz, Au = US$1,200/oz and Cu =
US$ 6,000/t. Revised estimate was not performed due to lack of material changes. Discrepancies in
calculations are due to rounding.
2. PdEq is calculated using the following formula: PdEq = Pd (g/t) + Pt (g/t)/2.35 + Au (g/t)/1.46 +
Cu (%)/0.76.
This estimate was prepared by employees of JSC Polymetal Management Company and JSC Polymetal
Engineering, led by Mr Valery Tsyplakov, who assumes overall responsibility for the Mineral Resources
and Ore Reserves Report.
Mr Tsyplakov is the employed full-time as the Managing Director of JSC Polymetal Engineering and has
more than 19 years' experience in gold, silver and polymetallic mining. He is a Fellow of the Institute
of Materials, Minerals & Mining (FIMMM), London, and a Competent Person under the JORC Code.
Listed below are other Competent Persons employed by the Company that are responsible for relevant
research on which the Mineral Resources and Ore Reserves estimate is based:
* Geology and Mineral Resources - Roman Govorukha, Head of Geologic Modelling and Monitoring
Department, JSC Polymetal Management Company, MIMMM, with 19 years' relevant experience;
* Mining and Ore Reserves - Igor Epshteyn, Head of Mining Process Department, JSC Polymetal
Engineering, FIMMM, with 38 years' relevant experience;
* Concentration and Metals - Igor Agapov, Deputy Director of Science and Technology, JSC Polymetal
Engineering, MIMMM, with 22 years' relevant experience.
All the above mentioned Competent Persons have sufficient experience that is relevant to the style of
mineralisation and types of deposits under consideration and to the activity being undertaken to
qualify as a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of
Exploration Results, Mineral Resources and Ore Reserves' (JORC Code).
All Competent Persons have given their consent to the inclusion in the report of the matters based on
their information in the form and context in which it appears.
Metals prices used in estimating Mineral Resources and Ore Reserves are listed below (unless otherwise
indicated in the footnotes of the above tables):
Au = US$ 1,200/oz
Ag = US$ 15.0/oz
Cu = US$ 5,500/t
Zn = US$ 2,200/t
Pb = US$ 2,000/t.

Appendix
Reporting of Metal Equivalents
Gold equivalent conversion ratio
GE=Me/k
Where Me is the evaluated metal content (silver g/t, copper %, zinc %, lead %)
Where k is the metal to gold equivalent conversion rate that is calculated considering the difference
in metals value issuing the following formula:
For silver: k= ((Au price/31.1035 - (Au price /31.1035 - Treatment charge Au)*(Royalty Au)/100 -
(Treatment charge Au))*(Recovery Au)) / ((Ag price/31.1035 - (Ag price/31.1035 - Treatment charge
Ag)*(Royalty Ag)/100 - (Treatment charge Ag))*(Recovery Ag)),
for copper or zinc or lead: k = 100*((Au price/31.1035) - (Au price/31.1035 - Treatment charge
Au)*(Royalty Au)/100 - (Treatment change Au))*(Recovery Au)) / ((Me price) - (Me price - Treatment
charge Me)*(Royalty Me)/100 - (Treatment charge Me))*Recovery Me)),
where Royalty is the mineral extraction tax at applicable rate, recovery - the life-of-mine expected
recovery of the respective metal in the processing technology applied.
