Wattle Dam Gold Mine

The Wattle quarry is situated in Wattleup, southern Perth Metropolitan Region, Western Australia — a low-relief coastal plain characterised by Tamala Limestone formations and aeolian limesand deposits. The flat to gently undulating terrain minimises overburden stripping ratios, enabling efficient mass earthmoving with reduced bench-height complexity. Proximity to the Kwinana Industrial Corridor provides direct logistical access to downstream processing facilities, cement plants, and construction supply chains within the Greater Perth Basin.

Operating continuously since WA Limestone Group's acquisition in 1973, Wattle functions as a DIDO (Drive-In Drive-Out) operation leveraging Perth Metro's skilled labour pool. The critical B2B vulnerability lies in mobile plant downtime — drill rigs, loaders, and articulated haulers require rapid-response mechanical support. Local workshops in Bibra Lake and Kwinana Industrial Area are strategically positioned to deliver OEM parts and hydraulic servicing, minimising Mean Time To Repair (MTTR) and protecting production continuity for limestone and limesand output.

Wattle's extraction circuit centres on drill-and-blast or rip-and-load methodology suited to soft-to-medium Tamala Limestone. Primary crushing via jaw or impact crushers feeds downstream screening decks calibrated for:

• Aggregate grading (road base, drainage fill)
• Limesand classification for agricultural and construction markets
• Sized limestone for lime burning and industrial applications

No flotation circuit is required given the sedimentary purity of the deposit. Physicochemical QA focuses on CaCO₃ content, particle size distribution, and moisture control at point of dispatch.

As a Perth Metro operation, Wattle is subject to EPA Western Australia environmental conditions and DMP rehabilitation bonds. Key ESG pressure points include:

• Progressive land rehabilitation and native vegetation offset obligations
• Dust suppression management in proximity to residential Wattleup/Henderson zones
• Fleet electrification pathway aligned with WA Government's decarbonisation targets
• Short haul distances reducing Scope 3 transport emissions versus regional quarries

Urban-adjacent positioning creates both compliance intensity and a competitive ESG advantage through reduced logistics carbon footprint.
