Mine Life2028
ShapshotGold production started at Sunrise Dam in 1997. Underground mining is now the primary source of ore for the operation. Reintroduction of open pit mining in 2021 for the Golden Delicious satellite open pit has supplemented the mill feed from the underground, supplying 50% of 2022 mill capacity.

Summary:

Deposit type
Sunrise Dam is considered to be a mesothermal gold deposit, typical of many orebodies found in the Archaean Greenstone Belts of Western Australia

Mineralisation style
At Sunrise Dam, gold mineralisation is structurally controlled, and vein-hosted.

The style of mineralisation can be differentiated depending on the structure or environment in which it is hosted.

There are three dominant styles recognised:
• Shear-related and high-strain e.g. Sunrise Shear Zone
• Stockwork development in planar faults with brittle characteristics (these occur in all rock types and are commonly concentrated at contacts within the volcanic stratigraphy or the porphyry margin and within hinge positions within the magnetite shales) e.g. Cosmo, Dolly and Vogue orebodies
• Placer-style mineralisation hosted within the palaeo-fluvial sediments, near surface

Gold mineralisation at Golden Delicious is hosted by a suite of granitoids, which intrude intermediate to mafic volcanic and volcaniclastic greenschist host rocks. The area has been deeply weathered, partly eroded and blanketed by transported lateritic gravels.

Mineralisation characteristics
Mineralisation is typically hosted in quartz-carbonate veins and breccias with varying quantities of pyrite and arsenopyrite. Gold occurs as free gold and is also occluded in the sulphides. The gold mineralisation is often associated with strongly altered country rocks proximal to the shear and fracture network that the hydrothermal fluids have passed through.

At Golden Delicious, the majority of the gold mineralisation is hosted within the monzonite and, to a lesser extent, the syenite and granite. Gold observed in thin section is typically spatially associated with pyrite stringers and as inclusions within altered feldspars or carbonate.
