Cutler

The Cutler quarry is situated at Cutler Road, Nowergup, within the South West Metropolitan Formations district of Western Australia's Perth Metro Region. Operating within the Swan Coastal Plain, the site benefits from proximity to Perth's urban fringe, significantly reducing haul distances compared to remote operations. This near-metro positioning compresses supply chain lead times for construction aggregates, yet demands strict compliance with peri-urban land-use and environmental buffer regulations governing active extraction zones.

Currently classified as Operating, the Cutler site is a dual-operator asset managed by LIMESTONE BUILDING BLOCKS COMPANY PTY. LTD. and PMR Quarries Pty Ltd. The near-Perth location enables a DIDO (Drive-In Drive-Out) workforce model, eliminating the need for rotational FIFO rosters or remote camp infrastructure. Key operational B2B considerations include:

• Daily workforce mobilisation from Perth metropolitan catchment
• Short-cycle procurement and just-in-time aggregate delivery
• Dual-operator structure requiring coordinated scheduling and resource allocation
• Direct supply to Perth residential and civil construction markets

The Cutler operation extracts limestone and limesand via open cut methodology, typical of Swan Coastal Plain shallow-profile deposits. Material handling relies on wheeled loaders and rigid-frame haul trucks given the low-relief terrain. While large-scale conveyor systems are not the primary handling method at this scale, any processing upgrade toward fixed crushing and screening circuits would necessitate engineered conveyor integration to optimise throughput and minimise double-handling. Key infrastructure elements include:

• Open bench extraction with shallow overburden stripping
• On-site primary crushing and screening capability
• Direct load-out to road transport for metro delivery

Operating within the Perth Metro Region imposes Heritage compliance obligations under the WA Aboriginal Heritage Act, requiring systematic survey and clearance protocols prior to any pit extension. ESG priorities for B2B procurement engagement include:

• Aboriginal Heritage survey clearance for all new extraction footprints
• Preferential engagement with local Aboriginal-owned enterprises for civil, rehabilitation and environmental services
• Progressive rehabilitation and native vegetation reinstatement per DMP conditions
• Dust and noise management plans aligned with peri-urban residential sensitivity
• Carbon footprint reduction through short-haul logistics optimisation
