l Aktogay
§ Copper production1 in Q3 of 37.3 kt, in line with previous quarter (Q2 2019: 37.4 kt), as high sulphide copper grade and throughput levels maintained
§ Full year copper production1 expected to be at upper end of guidance range of 130-140 kt
l Bozshakol
§ Copper production2 increased by 38% to 32.1 kt (Q2 2019: 23.3 kt) and gold production2 rose by 47% to 43 koz (Q2 2019: 30 koz), a record quarter for Bozshakol
§ Ore processed increased by 30% to 8,378 kt (Q2 2019: 6,438 kt) as both plants operated without major scheduled maintenance and average copper and gold grades increased, as planned

NOTES TO EDITORS
The Group's new operations at Bozshakol and Aktogay have delivered industry leading production growth and transformed
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 38 years at an average copper grade of 0.37%. The mine and processing facilities commenced output in 2016 and will produce an average of 100 kt of copper cathode equivalent and 120 koz of gold in concentrate per year over the first 10 years of operations.
Aktogay is a large scale, open pit mine similar to Bozshakol, with a remaining mine life of 27 years (including the expansion project) at an average copper grade of 0.36% (oxide) and 0.33% (sulphide). Aktogay commenced production of copper cathode from oxide ore in

Ore extraction at Aktogay increased by 13% to 14,883 kt (Q2 2019: 13,199 kt). Sulphide ore extraction of 9,271 kt (Q2 2019: 8,186 kt) was 13% higher than the previous quarter and exceeded sulphide processing volumes of 6,119 kt (Q2 2019: 6,293 kt), as additional low grade ore was extracted and stockpiled in preparation for the Aktogay expansion project. Oxide ore extraction also increased by 12% to 5,612 kt (Q2 2019: 5,013 kt) ahead of the winter period. Total ore extraction in the first nine months of 2019 was 39,099 kt, representing an increase of 27% compared to the prior year comparative period (9m 2018: 30,716 kt), mainly driven by the increased mining of sulphide ore.
Sulphide ore processing volumes of 6,119 kt were 3% below the previous quarter (Q2 2019: 6,293 kt), whilst processing volumes in the first nine months of 2019 were 24% higher than the prior year comparative period (9m 2018: 15,254 kt) as the sulphide concentrator has operated at its full design capacity during 2019.
Copper production from sulphide ore of 30.6 kt was 2% lower than the previous quarter (Q2 2019: 31.3 kt) due to reduced processing volumes partially offset by a higher average copper grade of 0.60% (Q2 2019: 0.59%). Copper production from sulphide in the first nine months of 2019 was 92.9 kt, representing a 21% increase on the prior year comparative period when the sulphide plant was still ramping up to design capacity (9m 2018: 76.5 kt).
Copper cathode production from oxide ore increased to 6.7 kt in the quarter (Q2 2019: 6.1 kt) and remains on track to achieve the full year guidance of approximately 25 kt. Copper cathode production of 18.5 kt over the first nine months of 2019 was broadly in line with the prior year comparative period (9m 2018: 18.9 kt).
Total copper production of 37.3 kt was in line with the previous quarter (Q2 2019: 37.4 kt) as higher oxide output offset lower sulphide production. In Q4 2019, copper production is expected to be less than Q3 2019 due to seasonally reduced oxide output, lower grades and scheduled maintenance at the sulphide plant in December. After a good third quarter, copper production at Aktogay is now expected to be at the upper end of the full year guidance range of 130-140 kt.

Ore extraction at Bozshakol increased by 6% to 9,132 kt (Q2 2019: 8,608 kt) mainly due to increased mining of sulphide ore to feed the main concentrator, which processed a record 6,791 kt of ore during the period (Q2 2019: 5,647 kt). Ore extraction in the first nine months of 2019 increased to 26,634 kt (9m 2018: 23,238 kt) as additional clay material was mined to access higher grade sulphide ore areas.
Ore processed increased by 30% to 8,378 kt (Q2 2019: 6,438 kt) following the completion of upgrade works to the clay plant during the second quarter of 2019 and the absence of any major scheduled maintenance at the sulphide plant. The average copper recovery rate reduced slightly to 80.4% (Q2 2019: 82.6%) reflecting the increased contribution from the clay plant where recovery rates are lower than in the main concentrator. The average copper grade processed increased to 0.50%, in line with the mine plan.
In the first nine months of 2019, ore processing volumes increased by 3% to 21,626 kt (9m 2018: 20,983 kt) and the average copper recovery rate improved to 81.8% (9m 2018: 78.2%), more than offsetting the lower average copper grade of 0.47% (9m 2018: 0.48%).
Copper production benefited from a significant increase in ore throughput and higher grades in Q3, as expected, rising by 38% to a record level of 32.1 kt (Q2 2019: 23.3 kt). Copper production for the first nine months of 2019 was 79.2 kt (9m 2018: 75.0 kt), driven by higher ore throughput and an improved average recovery rate. Whilst throughput is expected to be lower in Q4 2019 due to scheduled maintenance, following the performance in Q3 Bozshakol remains on track to achieve its full year copper production guidance range of 105-115 kt in 2019.
Gold production in Q3 increased to 43.4 koz (Q2 2019: 29.6 koz) in line with the rise in copper production, supported by a higher gold grade of 0.28 g/t (Q2 2019: 0.25 g/t). Gold production at Bozshakol for the first nine months of 2019 increased to 103.0 koz (9m 2018: 93.7 koz) and is on track to achieve the upper end of the full year guidance range of 130-140 koz.
Silver production was 233 koz in Q3 (Q2 2019: 165 koz) and 567 koz in the first nine months of 2019 (9m 2018: 494 koz) and is on track to achieve full year guidance of approximately 700 koz.

Ore extraction reduced by 2% in Q3 to 979 kt (Q2 2019: 995 kt) due to lower mined volumes at Orlovsky. Ore processing volumes also reduced to 982 kt from 1,168 kt in the previous quarter due to lower throughput at the Nikolayevsky concentrator. Ore extraction volumes of 2,921 kt in the first nine months of 2019 were in line with the prior year comparative period (9m 2018: 2,929 kt) whilst ore processing volumes were 9% lower at 2,775 kt (9m 2018: 3,048 kt) due to the intentional idling of the Nikolayevsky concentrator over the first quarter of 2019.
The average copper grade processed reduced slightly to 1.62% in Q3 from 1.68% in the previous quarter due to the mining of lower grade zones at Orlovsky, whilst the average recovery rate at the
In the first nine months of 2019, lower processing volumes and a reduction in average copper grades to 1.69% (9m 2018: 1.80%) led to a 14% decrease in copper production to 39.9 kt (9m 2018: 46.4 kt), in line with management expectations.
Gold production of 14.4 koz increased by 4% versus the previous quarter (Q2 2019: 13.9 koz) as higher grades and recovery rates more than offset the reduction in processing volumes. Gold production in the first nine months of 2019 was 40.8 koz (9m 2018: 41.0 koz) and the
Silver production was 583 koz in Q3 (Q2 2019: 616 koz) and 1,513 koz in the first nine months of 2019 (9m 2018: 1,725 koz) and is on track to exceed full year guidance of around 1,800 koz.
Zinc in concentrate production of 10.5 kt in Q3 was 14% lower than the previous quarter (Q2 2019: 12.2 kt) as a decrease in ore processing volumes was offset by an increase in average zinc grade processed to 2.22% (Q2 2019: 1.96%). Zinc in concentrate output of 28.9 kt in the first nine months of 2019 (9m 2018: 38.3 kt) was 25% lower than the prior year comparative period due to lower grades.

Total copper sales volumes of 232.6 kt were in line with production. Copper cathode sales increased by 32% to 100.9 kt (9m 2018: 76.5 kt) whilst copper in concentrate sales reduced by 7% to 131.7 kt (9m 2018: 142.2 kt). The higher proportion of cathode sales was mainly due to increased toll processing of material from Aktogay at the Balkhash smelter in
Gold sales volumes of 168.7 koz were significantly above production as sales include 25.6 koz of Bozshakol gold bar inventory accumulated at the end of 2018, as reported in the 2019 half year results.
