Press Release 29 April 2021
Polyus reports Ore Reserves of 104 Million Ounces Gold
PJSC Polyus (LSE, MOEX — PLZL) (“Polyus”, the “Company”) announces its Ore Reserves and Mineral Resources estimates as at 31 December 2020, in accordance with JORC Code 2012.
The Company’s total Proved and Probable Ore Reserves have increased 71% to 104 million ounces of gold, compared to 61 million ounces of gold as at 31 December 2019. The updated estimate primarily reflects the inclusion of Ore Reserves for Sukhoi Log as well as additions at several operating mines, derived from a comprehensive drilling program across the Company’s asset portfolio launched in 2018.
The Measured, Indicated and Inferred Mineral Resources are estimated at 204 million ounces of gold, compared to 188 million ounces of gold as at 31 December 2019.
Pavel Grachev, Chief Executive Officer of PJSC Polyus, commented:
“Polyus is now confirmed to have the largest reserve base globally, with approximately 97% of these reserves attributable to our operating mines and our flagship greenfield project, Sukhoi Log, where we plan to complete the Bankable Feasibility Study and make a final investment decision on the project in 2022. This is further confirmation of the Company’s ability to maintain long-term sustainable gold production. We will proceed with exploration activities across the group aimed at expanding our resource base.”
Ore Reserves Highlights
- Polyus’ Ore Reserves are estimated at 104 million ounces of gold, up from 61 million ounces of gold as at 31 December 2019 and allow for mining depletion. This increase mainly reflects:
o The addition of a maiden Ore Reserve estimate of 40 million ounces of gold for Sukhoi Log.
o Revisions to Ore Reserve estimates for Blagodatnoye Kuranakh and Verninskoye, following mining studies update and preparation of new resource
models for Blagodatnoye and Kuranakh as a result of a comprehensive exploration program initiated in 2018.
o At Blagodatnoye, the completed drilling program allowed for pit shell expansion down to -160 mrl from -70 mrl, resulting in an increase of 3.6 million ounces of gold in the Ore Reserve estimate, before accounting for mining depletion.
o At Kuranakh, Polyus conducted more than 200 kilometres of drilling at several mines of the Kuranakh ore field in 2018-2020. This facilitated more accurate definition of gold mineralization and allowed to update resource models of these mines, resulting in an increase of 2.4 million ounces of gold in the Ore Reserve estimate, before accounting for mining depletion.
- At Olimpiada, Natalka, and Alluvials Polyus only reported mining depletion.
- 58% of the Company’s estimated Ore Reserves of gold are located within its operating assets:
o Polyus Krasnoyarsk has the largest share of the Company’s Ore Reserves among operating assets, with 23 million ounces of gold at Olimpiada and 12 million ounces of gold at Blagodatnoye.
o Natalka has an estimated Ore Reserve of 14 million ounces of gold.
o Ore Reserves at Kuranakh, Verninskoye and Alluvials contain 6.4 million ounces, 4.5 million ounces and 0.54 million ounces, of gold respectively.
- 38% of the estimated Ore Reserves are attributable to Polyus’ key greenfield project, Sukhoi Log
- An average gold grade in the Company’s Ore Reserve estimates stands at 1.9 g/t, compared to 1.8 g/t as at 31 December 2019.
o Approximately 1,506 million tonnes of Ore Reserve, containing 97 million ounces of gold out of the total 104 million ounces, are expected to be mined by conventional open pit truck-and-shovel or underground mining methods at a gold grade of 2.0 g/t.
o The remaining Ore Reserve totalling 234 million tonnes is lower grade and stored in stockpiles or in situ at the Alluvial operations.
Mineral Resources Highlights
The Company’s Mineral Resources are estimated at 204 million ounces of gold, compared to 188 million ounces as at 31 December 2019. This increase mainly reflects:
- Updated Mineral Resource estimates for Olimpiada, Blagodatnoye, Verninskoye, Kuranakh and Sukhoi Log, following mining studies update and preparation of new resource models.
- Approximately 60% of the Company’s Mineral Resources are attributable to operational mines:
o Olimpiada’s Mineral Resource is estimated at 49 million ounces of gold.
o Natalka’s Mineral Resource amounts to 32 million ounces of gold.
o Blagodatnoye’s Mineral Resource stands at 17 million ounces of gold.
o Verninskoye and Kuranakh Mineral Resources are estimated to be 14 million ounces and 11 million ounces, of gold respectively.
2021 Exploration Highlights
- The Company continues its deep levels exploration program of Olimpiada and plans to drill approximately 35 kilometres in 2021.
- Polyus is also proceeding with exploration activities at Kuranakh. In 2021, the Company expects to drill more than 100 kilometres, while exploration activities at Kuranakh will continue in 2022 and 2023.
- At Sukhoi Log, Polyus is progressing with its deep-level and flank exploration drilling campaign. As the Sukhoi Log ore body extends below the limits of the verification and exploration drilling, Polyus has initiated additional deep-level drilling aimed at estimating resources below the current exploration horizon. Flank exploration is focused on the Northern and Eastern parts of the ore body in order to define its dimensional limits and explore potential satellite ore formations. The Company plans to drill 40 kilometres at Sukhoi Log in 2021.
