Kanowna Belle Operations is part of Northern Star's broader Kalgoorlie Operations. The underground mine has been in operation since 1995. The deposit is categorised as a refractory, Archean lode-gold type deposit. Gold mineralisation is primarily hosted within a large porphyritic granodiorite body and is associated with the Fitzroy Shear Zone. The ore is considered "refractory" as the gold is not easily recoverable through a conventional carbon-in-pulp (CIP) circuit, requiring additional processing via roasting.

The adjacent Kanowna Belle processing plant has an annual throughput capacity of approximately 2 million tonnes.

The adjacent Kanowna Belle processing plant has an annual throughput capacity of approximately 2 million tonnes. The facility is equipped to treat both free-milling and refractory ores, featuring a flotation circuit, a concentrate roaster circuit, and a carbon-in-leach (CIL) circuit. Ore is sourced from the Kanowna Belle and South Kalgoorlie (HBJ) underground mines for processing at the Kanowna Belle mill. The primary mining method is a form of modified open stoping, including longhole open stoping (LHOS), with open stopes backfilled with paste fill created from tailings. The ore is accessed via drives on level spacings of 30 metres.
