KAZ Minerals' copper production increased by 80% to 259 kt in the year to the end of December.
The group said this was at the top of February 2017 guidance (225-260 kt) and in line with the updated range (250-270 kt).
KAZ said full year gold production of 179 koz was at the upper end of guidance range (160-180 koz).
It said Q4 copper production totalled 65 kt (Q3 2017: 75 kt) reflecting expected grade reduction at Aktogay and Bozshakol concentrator maintenance.
Chief executive Andrew Southam said: 'I am pleased that in 2017 we achieved copper production targets across all of our assets including at Aktogay, where we launched sulphide production in February 2017 and declared the concentrator commercial in October.
'The performance of our two recently commissioned mines at Bozshakol and Aktogay has delivered an 80% increase in annual copper output into a tightening market and gold production at the top of our guidance range.'
