Summary:

Kalgoorlie Operations consisted of three separate mining areas, Kanowna Belle, South Kalgoorlie Operations (SKO) and the greater Kundana area. The sale of Northern Star's EKJV, Kundana and Carbine assets completed on 18 August 2021. Kanowna Kanowna Belle is located within the Kalgoorlie Terrane, one of a number of elongate, broadly NNW-SSE striking structural-stratigraphic late Archaean greenstone terranes of the Eastern Goldfields of Western Australia. The Kanowna Belle gold mine is located close to the centre of the NNW-SSE trending, greenstone-dominated Boorara Domain, the eastern most subdivision of the Kalgoorlie Terrane. The Kanowna Belle deposit can be categorised as a refractory, Archean lode-gold type deposit. The orebody is comprised of several ore shoots, including the large Lowes Shoot, and several smaller lodes including Troy, Sims, Hilder, Hangingwall and Footwall shoots controlled by sets of structures of various orientations oblique to Lowes. Mineralisation is mainly hosted within a large porphyritic granodiorite body (Kanowna Belle Porphyry) that has intruded a sequence of sedimentary and volcaniclastic rocks. A zone of intense structural disruption (Fitzroy Shear Zone) separates the deposit into hangingwall and footwall structural domains and is the primary control on gold distribution. Gold mineralisation is locally associated with quartz-carbonate stockwork veins, breccia zones, sulphide-quartz-carbonate stringers and sheeted vein arrays. The generally ........

Summary:

Kalgoorlie Operations consisted of three separate mining areas, Kanowna Belle, South Kalgoorlie Operations (SKO) and the greater Kundana area. The sale of Northern Star's EKJV, Kundana and Carbine assets completed on 18 August 2021. In FY22 Kalgoorlie Operations sourced ore primarily from the Kanowna Belle and HBJ underground mines. Kanowna Belle The Kanowna Belle gold deposit is mined by longhole stoping and underhand longhole bench stoping with paste fill methods. This mining method was selected to minimise the impact of mining induced stress on the underground operations by geotechnical driven mining sequences and a fill system integral in the mining cycle. The mining method used at Kanowna Belle underground is called longhole open stoping (LHOS). Mining of the LHOS commences with the development of drives (tunnels) on each level and the sides of these are supported by cement grouted roof bolts, mesh and shotcrete. These drives delineate the boundary of the stope. Each LHOS is 15-30m wide, up to 50m long and 120m high. Depending on size each stope may contain between 20,000 to 50,000 tonnes of ore. The Kanowna Belle gold mine has been extracted down to a depth of 1,301m below surface with a possible extension into lower E block, further development of the Troy and Sims loads located in the hangingwall, higher in the mine. The Velvet deposit sitting 500m west of the main Lowes ore body is also a substantial part of the production and open a depth. All mining operatio ........


Crushing and Grinding
Flow Sheet: Source

Kanowna Belle The crushing and grinding circuits are common for the free milling and refractory circuits. The crushing circuit is a simple single stage circuit with a 240t capacity ROM bin feeding a Jaques double toggle 60x48 (185kw) crusher at a 420tph crushing capacity. The crushed ore, nominally minus 125mm reports to a 20,000t partially-covered coarse ore stockpile with a live capacity of about 1,000t. This product is then reclaimed by an apron feeder and two vibrating feeders located under the stockpile and discharged onto a conveyor belt. The crushed ore is then conveyed to the grinding circuit. The grinding circuit comprises an ANI Products 7.32m x 3.35m SAG mill operating in closed circuit with a Metso Nordberg HP200 recycle cone crusher and an ANI Products 4.72m x 7.01m Ball mill in closed circuit with cyclones. The SAG mill has a grate discharge and is steel lined, while the Ball mill has a trommel screen discharge and is rubber lined. The SAG mill has a variable speed drive with a range of 10 to 12 rpm, while the Ball mill has a fixed speed drive at 14.0 rev/min (72% of critical). The installed power for the SAG and Ball mills is 2,850kW. The grinding circuit throughput is currently around 240 – 250tph. South Kalgoorlie The crushing circuit is three-stage consisting of a primary jaw crusher feeding a 6,000t live capacity coarse ore bin, operating at an average rate of 350 t/h, and a secondary and tertiary crusher circuit closed by a vibrating screen operating at an average rate of 200 t/h. The -8 mm crushing circuit product reports to the 3,500t live capacity fine ore bin. Ore from the fine ore bin is fed to the grinding circuit via conveyor, quicklime is added to the belt for pH adjustment. The grinding circuit consists of a primary and secondary mill in closed circuit with hydrocyclones. The fine particles (80% less than 0.150 mm) report to the cyclone overflow, which is fed to the leaching circuit.
