BAIMSKAYA TASED STATUS CONFIRMED

As previously announced, the Baimskaya project is located in a Territory of Accelerated Social and Economic Development ('TASED') and is therefore eligible for certain tax incentives to encourage investment. KAZ Minerals has today signed an agreement in a public ceremony with the Far East Development Corporation JSC, wholly owned by the Ministry for the Development of the Russian Far East and Arctic, which confirms TASED residency for the Baimskaya project. Securing the TASED status is consistent with the Group's assumptions when acquiring Baimskaya in January 2019 and with the project parameters update provided in November 2020.

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 0.27% (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 0.35%. The mine and processing facilities commenced output in 2016 and are expected to deliver 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 9.9 Mt of copper at an average grade of 0.39% and 16.6 Moz of gold at an average grade of 0.21 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.
