Primary Metals/Minerals
Copper.
Secondary Metals/Minerals
Small amounts of molybdenum.
Geology/Mineralisation
Aktogay is, geologically, situated within the Turkestan-Alai metallogenic province, characterised by its copper/gold porphyry deposits. The mineralisation at Aktogay is associated with a large copper/gold porphyry system, which formed during the Paleogene period through magmatic intrusions into the surrounding rocks.
The primary orebody at Aktogay comprises copper sulphides hosted within porphyritic intrusive rocks, typically granite or granodiorite. These sulphides include chalcopyrite, bornite, and chalcocite, which are the main sources of copper. Additionally, gold and molybdenum are present as by-products in the ore.
Reserves
Not stated.
Resources
As at December 2022, Aktogay had mineral resources estimated at 1.92-billion tons, with a copper grade of 0.33%.
Type of Mine
Openpit.
Mining Method
Truck-and-shovel.
Major Infrastructure/Equipment
The Aktogay site has a sulphide ore processing capacity of 50-million tonnes a year from two concentrators.

Prospects
Aktogay is expected to produce an average of 170 000 t/y of copper from 2022 to 2027.
