Q2 2026 Production Report

PRODUCTION AND SALES REPORT FOR THE SECOND QUARTER ENDED 30 JUNE 2026

HIGHLIGHTS

• Copper

Copper production of 179.8 kt in H1 2026 was 2% lower than the prior year comparative period, primarily reflecting reduced output at Bozshakol, due to lower processing volumes, and at the East Region, due to lower grades processed. Aktogay delivered solid operational results during the period. Copper sales of 172.9 kt were 4% below production, driven by shipment timing differences and increased volumes of cathodes in transit and smelter work-in-progress at period-end.

• Precious metals

Gold and silver production in H1 2026 declined compared with the prior year comparative period, mainly reflecting lower output at Bozshakol following changes in ore characteristics, partly offset by stable production at Aktogay and the East Region & Bozymchak.

• Zinc in concentrate

Zinc in concentrate production increased by 6% to 21.7 kt in H1 2026, supported by higher average zinc grades processed. Q2 2026 production of 11.3 kt was 9% above the prior quarter, reflecting higher processing volumes.

• Molybdenum in concentrate

Molybdenum in concentrate production of 2,205 t in H1 2026 was 3% lower than the prior year comparative period due to lower output at Aktogay impacted by lower grades, partly offset by higher production at Bozshakol.

Andrei Tretyakov, Chief Executive Officer, said: “KAZ Minerals delivered a solid operational performance in the first half of 2026, producing 179.8 kt of copper. Strong output from Aktogay, combined with quarter-on-quarter improvements at Bozshakol, supported the Group’s production results during the period. Our focus remains on efficient operations while delivering our full-year production objectives”.
