- •
The Nurkazgan deposit is the largest porphyry Cu–Au deposit in Kazakhstan.
- •
The host rocks consist of granodiorite porphyry, quartz diorite porphyry, quartz diorite and diorite.
- •
Zircon U–Pb dating yields the Nurkazgan deposit formed at Silurian (440–437 Ma) rather than Devonian.
- •
Ore-bearing magmas derived from the lithospheric mantle in a Silurian intra-oceanic island arc setting.
