  • Volumes of ore processed increased 5% on a year-on-year basis to 24,815 thousand tonnes, primarily due to higher processing volumes at Kuranakh.
  • Recovery rate stood at 83.6%, up 0.9 ppts from the first half of the previous year, primarily driven by an increase in recoveries at Olimpiada and Blagodatnoye.
  • Doré gold output stood at 1,481 thousand ounces in the first half of 2024, a 5% increase on the first half of 2023.
  • Total gold output increased 3% and amounted to 1,473 thousand ounces compared to 1,436 thousand ounces in the same period of the previous year.

Operating Results FOR 1H 2024

Olimpiada

1H 2024 Highlights

  • Volumes of ore processed amounted to 7,541 thousand tonnes, remaining flat on the first half of 2023.
  • Average grades in ore processed decreased 14% year-on-year to 3.51 g/t.
  • Recovery rate rose to 84.5% (82.9% in 1H2023).
  • Total gold output was 740 thousand ounces, down 6% compared to the first half of 2023.

Gold output

Doré gold output in the first half of 2024 reached 740 thousand ounces, down 6% compared to the first half of 2023, driven by lower average grades in ore processed, which was partially offset by higher recovery rate. Total gold output (refined and in concentrate) also declined 6% compared to the same period of the previous year to 740 thousand ounces, which includes 140 thousand ounces of gold contained in flotation concentrate. This decline was mainly driven by lower head grades at Olimpiada in the first half of 2024.

Over the course of the first half of 2024, flotation concentrate output declined to 60.5 thousand tonnes with volumes of gold contained in flotation concentrate amounting to 140 thousand ounces, compared to 94.5 thousand tonnes of flotation concentrate output with 221 thousand ounces of gold contained in the first half of 2023. This reflects lower processing volumes of antimony-rich ore at Olimpiada over the reporting period.

Mining works

In line with current year's mine plan Polyus intensified stripping activities at the fifth stage of the Vostochny pit. Hence, volumes of rock moved rose 19% year-on year and amounted to 31,949 km³. Volumes of ore mined totalled 14,429 thousand tonnes, down 20% year-on-year, reflecting the onset of final stage of ore mining from fourth stage of the Vostochny pit. At the same time, the average grades in ore mined went up 8% year-on-year to 3.12 g/t (2.89 g/t in 1H2023).

Ore processing

Volumes of ore processed amounted to 7,541 thousand tonnes in the first half of 2024, remaining broadly flat compared to the first half of 2023. The average grade in ore processed declined 14% to 3.51 g/t (4.09 g/t in the first half of 2023) mainly due to lower mining volumes of antimony-rich ore and run-of-mine ore as well as lower average grades in these types of ore. This decrease in head grades was in line with the mine plan. The recovery rate rose to 84.5% from 82.9% in the first half of the previous year.

This growth was attributable mostly to higher average grades in ore processed during the reporting period. At the same time, refined gold went down 6% year-on-year to 189 thousand ounces, reflecting the accumulation of unrefined gold.

Mining works

In line with the current year's mine plan, volumes of rock moved rose to 15,505 km³ from 13,885 km³ in the first half of 2023. As Polyus intensified mining activities at the higher-grade area at the second stage of the pit, volumes of ore mined increased by 78% year-on-year to 9,465 thousand tonnes. The average grades in ore mined improved to 1.05 g/t (1.00 g/t in 1H2023).

Ore processing

Kuranakh

1H 2024 Highlights

  • Volumes of ore mined increased 25% year-on-year to 5,982 thousand tonnes.
  • Average grades in ore processed at the Kuranakh mill rose 6% year-on-year to 1.23 g/t.
  • Recovery rate at the Kuranakh mill was 89.0%, (88.6% in 1H2023).
  • Refined gold output reached 140 thousand ounces, up 34% on the same period of the previous year.

Gold output

In the first half of 2024, doré gold output increased 43% year-on-year to 148 thousand ounces, reflecting higher volumes of ore processed at both the Kuranakh Mill and the heap leaching facilities, as well as higher head grades at the Kuranakh Mill. Refined gold output reached 140 thousand ounces, up 34% on the first half of the previous year.

Mining works

Volumes of rock moved amounted to 11,156 km³, a 20% increase on a year-on-year basis. Volumes of ore mined increased 25% compared to the first half of 2023 to 5,982 thousand tonnes, as Polyus intensified its mining activities. The average grades in ore mined grew 11% year-on-year to 1.11 g/t (1.00 g/t in 1H2023).

Ore processing

Volumes of ore processed at the Kuranakh Mill amounted to 3,938 thousand tonnes, up 38% on a year-on-year basis, mostly driven by an improved Mill hourly throughput as a result of the completion of the capacity expansion program of the Kuranakh Mill to 7.5 million tonnes per annum. Head grades stood at 1.23 g/t compared to 1.16 g/t in the same period of the previous year due to an increase in volumes of ore mined and higher average grades in ore mined.

Heap leaching

The amount of ore processed by Polyus at the Kuranakh heap leaching facilities in the first half of 2024 totalled 718 thousand tonnes, a 19% increase on the first half of 2023. This growth was attributable to favourable weather conditions that made it possible to begin leaching operations ahead-of-schedule. The average grade in ore processed rose 2% year-on-year to 0.87 g/t.
