PJSC Polyus
Operating results for the first half of 2022
Key Highlights
· Total gold output amounted to 1,068 thousand ounces, compared to 1,263 thousand ounces in the first half of 2021. This decline was driven by lower production of refined gold across all deposits due to lower average grades in ore processed. Doré gold volumes totalled 1,186 thousand ounces, down 9% year-on-year. The difference in total gold output and doré gold production reflects the accumulation of unrefined gold to be further processed in 2022.
· Volumes of ore mined decreased 16% year-on-year to 28,149 thousand tonnes, reflecting lower ore volumes mined across all operating assets except Kuranakh.
· Volumes of ore processed amounted to 23,777 thousand tonnes, up 2% on the same period of the previous year driven by higher processing volumes at Olimpiada, Verninskoye and Natalka.
· Recovery rate decreased to 81.8%, compared to 82.1% in the first half of 2021.

Ø Volumes of ore processed totalled 4,419 thousand tonnes.
Ø Recovery rate stood at 86.0%.
Ø Doré gold output amounted to 179 thousand ounces.
Gold output
Doré gold output in the first half of 2022 amounted to 179 thousand ounces, down 17% compared to the first half of 2021, mainly due to lower average grades in ore processed. Refined gold output decreased 18% year-on-year to 171 thousand ounces. On a semi-annual basis, doré gold output and refined gold output declined 20% and 22%, respectively.
Mining works
Volumes of rock moved rose 7% year-on-year and amounted to 39,590 thousand tonnes (14,187 km³).
Volumes of ore mined in the first half of 2022 decreased to 5,022 thousand tonnes, down 43% compared to the corresponding period of the previous year. Grades in ore mined declined 20% year-on-year to 1.06 g/t.
This decrease occurred due to the sequence of mining works. The Company has completed mining activities at the second stage of the pit, while operations at the third stage are temporarily conducted at lower-grade zones of the pit.
Ore processing
Compared to the first half of 2021, volumes of ore processed decreased 1% to 4,419 thousand tonnes in the reporting period. Following a temporary decline in grades in ore mined, grades in ore processed decreased to 1.48 g/t, from 1.73 g/t in the first half of 2021.
Despite a 14% decline in head grades, recovery rate decreased only by 0.6ppts to 86.0% on a year-on-year basis. Recovery rate was supported by the mineralogy of ore feed with minimal content of carbon and arsenic.
Mill 5
In the first half of 2022, the main contractor for the Mill 5 project completed the shift camp and was in the final stage of closing the thermal envelope of the buildings of comminution and hydromet circuits. Foundation works for an in-pit crushing and conveying (IPCC) system are in progress. Polyus is also advancing the installation of the SAG-mill. The construction of the Yenashimo river diversion channel and installation of reinforced-concrete structures of the river bridge were in progress.

Sukhoi Log
1H 2022
Ø Polyus is proceeding with project design.
Project developments
In the reporting period, the Company finalized the geotechnical parameters for the open pit and defined the specifications of the main technological equipment for the processing plant. Polyus has also finalized mine planning and processing plant design and progressed with the general layout, infrastructure and tailings storage facility design.
The Company has also finalized comprehensive engineering studies required for the feasibility study stage and progressed with engineering studies required for the project design documentation.
Additional drilling activity at Sukhoi Log
Polyus has drilled ca.31 km out of its 77 km 2022 in-fill drilling campaign. This will allow the Company to better define the gold mineralization within the future pit area, where Polyus expects to carry out mining activities during the first years of Sukhoi Log's operations, and enable more accurate planning and sequencing of the mining works.
Other activities
In the reporting period, the Company progressed with the construction project for the Vitim substation and 220 kV gridline, which are within Polyus' project scope for the technical connection of Sukhoi Log to the existing power grid.
Polyus has also completed a detailed instrumental survey of bridges and roads on the Taksimo - Sukhoi Log route. This exercise is required for the construction and operation of the Sukhoi Log external infrastructure.
