NOTES TO EDITORS
KAZ Minerals PLC ("KAZ Minerals" or "the Group") is a high growth copper company focused on large scale, low cost, open pit mining in Kazakhstan, Russia and Kyrgyzstan. It operates the Aktogay and Bozshakol open pit copper mines in the East Region and Pavlodar region of Kazakhstan, three underground mines and associated concentrators in the East Region of Kazakhstan and the Bozymchak copper-gold mine in Kyrgyzstan. In 2020, total copper production was 306 kt with by-products of 196 koz of gold, 3,374 koz of silver and 50 kt of zinc in concentrate. The Group acquired the Baimskaya project in the Chukotka region of Russia in January 2019, one of the world's most significant undeveloped copper assets, with the potential to become a large scale, low cost, open pit copper mine.
The Group's major operations at Aktogay and Bozshakol have delivered industry leading production growth and transformed KAZ Minerals into a company dominated by world class, open pit copper mines.
Aktogay is a large scale, open pit mine with a remaining mine life of around 25 years (including the expansion project) at an average copper grade of 0.35% (oxide) and 0.33% (sulphide). Aktogay commenced production of copper cathode from oxide ore in December 2015 and copper in concentrate from sulphide ore in February 2017. The operating sulphide concentrator has an annual ore processing capacity of 25 million tonnes and the sulphide processing capacity is expected to be doubled to 50 million tonnes with the addition of a second concentrator by the end of 2021. Aktogay is competitively positioned on the global cost curve and is expected to produce an average of 100 kt of copper per year from sulphide ore until 2021, increasing to 170 kt per year from 2022 to 2027, after the second concentrator commences operations. Copper production from oxide ore is expected to be in the region of 20 kt per annum until 2024.
Bozshakol is a first quartile asset on the global cost curve with an annual ore processing capacity of 30 million tonnes and a remaining mine life of c.40 years at an average copper grade of 0.36%. The mine and processing facilities commenced output in 2016 and is expected to produce an average of 100 kt of copper production and 120 koz of gold in concentrate per year over the first 10 years of operations.
The Peschanka deposit within the Baimskaya licence area in Russia has JORC measured, indicated and inferred resources of 9.5 Mt of copper at an average grade of 0.43% and 16.5 Moz of gold at an average grade of 0.23 g/t. The project is located in a region identified by the Russian Government as strategically important for economic development and is expected to benefit from the construction of some state-funded power and transport infrastructure and the provision of tax incentives. The estimated capital budget for construction is close to $8 billion.
KAZ Minerals is listed on the London Stock Exchange and the Kazakhstan Stock Exchange and employs around 16,000 people, principally in Kazakhstan.

Ore extraction in Q4 was 38% higher at 12,513 kt (Q3 2020: 9,059 kt) as oxide ore volumes increased following the recommencement of oxide mining in September with 5,427 kt extracted in Q4 (Q3 2020: 1,360 kt). Sulphide ore extraction of 7,086 kt was 8% lower than the previous quarter (Q3 2020: 7,699 kt) but continued to exceed sulphide concentrator throughput volumes as lower grade material was stockpiled during the quarter.
Q4 sulphide ore processing volumes increased to 6,057 kt (Q3 2020: 5,737 kt) as maintenance was completed efficiently during the period. The average grade of sulphide ore processed in Q4 of 0.56% was in line with the previous quarter (Q3 2020: 0.56%) and slightly higher than expected. The average copper recovery rate reduced to 84.6% (Q3 2020: 86.1%) due to a temporary variation in the ore feed blend in the fourth quarter. Copper production from sulphide ore of 27.3 kt was 3% higher compared to the previous quarter (Q3 2020: 26.5 kt) mainly due to the 6% increase in processing volumes, offset by the lower average recovery rate.
Copper cathode production from oxide ore reduced, as expected, to 4.6 kt in Q4 from 5.2 kt in Q3 2020 due to seasonal temperature variation.
Ore extraction over the full year reduced by 25% to 41,246 kt (FY 2019: 55,134 kt), mainly driven by the temporary suspension of oxide ore mining in Q2 and Q3, due to cathode production focusing on the re-irrigation of previously extracted material. Sulphide ore extraction of 30,788 kt (FY 2019: 35,731 kt) continued to exceed the processing capacity of 25 Mtpa as mine development works and stockpiling were undertaken ahead of the commissioning of the Aktogay expansion project.
Full year sulphide processing volumes reduced by 4% to 24,138 kt (FY 2019: 25,230 kt) mainly due to the timing of maintenance at the sulphide plant where a mill relining postponed from Q4 2019 was completed in January 2020, followed by two further relinings over the remainder of the year. The average copper grade processed in 2020 reduced, as expected, to 0.56% (FY 2019: 0.58%) but remained at elevated levels compared to the copper resource grade of 0.33%.
Full year copper production from sulphide ore of 109.9 kt was at the upper end of guidance but 11% below the 123.0 kt produced in 2019 due to the 4% decrease in ore throughput in combination with lower grades and recoveries. Copper cathode output from oxide ore in 2020 reduced by 6% to 21.3 kt from 22.7 kt in the prior year but remained above the long term guidance level of c.20 ktpa until 2024. Aktogay achieved total copper production of 131.2 kt in 2020, compared to full year guidance of 120-130 kt, supported by higher than expected grades.

Ore extraction of 9,833 kt in Q4 was 23% above the previous quarter (Q3 2020: 7,995 kt). Sulphide ore extraction increased by 5% to 6,824 kt (Q3 2020: 6,486 kt) in line with the requirements of the main concentrator. Clay ore extraction of 3,009 kt (Q3 2020: 1,509 kt) exceeded the rate required to supply the clay plant as ore was stripped to allow access to sulphide material.
Ore processing volumes in Q4 reduced, as expected, to 7,867 kt (Q3 2020: 8,116 kt) due to scheduled mill relinings at both concentrators which were completed in October.
The average copper grade processed in Q4 increased to 0.52% (Q3 2020: 0.49%) with an average of 0.51% in sulphide ore and 0.61% in clay ore, as higher grade stockpiled ore was blended into the ore feed. Copper production increased to 31.3 kt in Q4 (Q3 2020: 30.3 kt) as the higher average copper grade was partially offset by lower ore throughput.
Gold production in Q4 decreased by 15% to 31.4 koz (Q3 2020: 37.0 koz) due to the lower volume of ore processed, average grades of 0.24 g/t (Q3 2020: 0.25 g/t) and a low recovery rate of 56.0% (Q3 2020: 60.5%). Average gold recovery rates were temporarily impacted towards the end of the year by high sulphur content in the main concentrator feed and the processing of some oxidised ore at the clay plant.
Ore extraction in 2020 decreased to 32,090 kt compared to 35,693 kt in 2019 when 5,865 kt of clay ore was stockpiled to access sulphide ore areas. Ore extraction volumes in 2020 were broadly in line with processing volumes.
Full year ore processing volumes increased to 31,618 kt (FY 2019: 29,470 kt) mainly due to additional volumes processed at the clay plant which was closed for over three months in the first half of 2019 during upgrade works to the process water and reclaim systems. Ore processed volumes in 2020 were above combined plants' design ore throughput of c.30 Mtpa.
Full year copper production of 122.0 kt was above guidance of 110-120 kt and 11% higher than the prior year (FY 2019: 110.2 kt) due to the higher volume of ore processed and stronger average copper grades, partially offset by lower recovery rates.
Gold production in 2020 of 151.7 koz was 5% above the prior year (FY 2019: 144.8 koz) and ahead of guidance of 140-150 koz due to the higher volume of ore processed, partially offset by lower average gold grades.
Full year silver production of 949 koz was ahead of guidance of c.700 koz and 18% higher than the prior year (FY 2019: 803 koz).

Ore extraction decreased to 690 kt in Q4 (Q3 2020: 997 kt) mainly due to the suspension of operations at the Bozymchak mine from 7 October to 26 December 2020 to ensure employee safety during a period of political instability in Kyrgyzstan.
Processing volumes in Q4 of 705 kt (Q3 2020: 976 kt) slightly exceeded mined volumes mainly due to the processing of stockpiled ore at the Nikolayevsky concentrator. Ore throughput at Nikolayevsky was lower than the previous quarter due to the commissioning of the new in-pit tailings facility during which time processing of ore from the Irtyshsky mine was temporarily halted.
The average copper grade of ore processed in Q4 increased to 2.07% (Q3 2020: 1.73%) mainly due to the processing of a reduced proportion of Bozymchak ore which has lower average copper grades compared with the East Region mines. Q4 copper production decreased by 12% to 12.5 kt (Q3 2020: 14.2 kt) mainly due to the temporary suspension of operations at Bozymchak as well as the transition to in-pit tailings at Nikolayevsky.
Full year ore extraction of 3,753 kt was 3% below the prior year (FY 2019: 3,879 kt) and ore processing volumes decreased by 9% to 3,466 kt (FY 2019: 3,791 kt) mainly due to the suspension of Bozymchak in the fourth quarter.
The average copper grade processed in 2020 increased to 1.78% (FY 2019: 1.71%) due to higher grades at Orlovsky and the reduction in processing volumes at Bozymchak where copper grades are lower.
Full year copper production of 52.5 kt was above guidance of c.50 kt but 5% lower than the previous year (FY 2019: 55.5 kt) mainly due to the temporary closure of Bozymchak.
Gold production decreased in Q4 to 4.5 koz (Q3 2020: 13.7 koz) due to the lost output from Bozymchak which contributed 10.2 koz of gold in Q3 2020. Full year gold production of 44.0 koz (FY 2019: 53.7 koz) was in line with guidance of 40-50 koz.
Silver output of 362 koz was 35% below the previous quarter (Q3 2020: 554 koz) due to the limited production from Bozymchak and lower average grades at East Region. Full year silver production of 1,946 koz (FY 2019: 2,024 koz) was in line with guidance of around 2,000 koz.
Zinc in concentrate production reduced in Q4 to 10.2 kt (Q3 2020: 15.7 kt) as mining took place in lower grade zinc areas in the Artemyevsky mine. Full year zinc in concentrate production of 49.7 kt was at the upper end of the guidance range of 45-50 kt.
