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]  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] 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.

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.
