McLarty Range

The McLarty Mine operates within the South West Metropolitan Fringe (South West M.F.) of Western Australia's Peel Region, a low-relief coastal plain characterised by sandy loams, wetland corridors, and seasonally high water tables. During intense winter rainfall events, haul road surfaces become critically compromised. Operators must implement geotextile-reinforced access roads and continuous mud management protocols — including gravel blinding layers and wheel wash stations — to maintain truck cycle times and prevent regulatory non-compliance under WA's Environmental Protection Act.

As a fully operational quarry under Carbone Bros Pty Ltd (100% ownership), McLarty supplies construction aggregates to Perth's expanding southern corridor. B2B procurement cycles are driven by civil construction demand peaks. Logistical complexity includes:

• DIDO roster management for plant operators and maintenance crews from Perth metro
• Coordination of heavy haulage schedules with Peel region road authority permits
• Vendor qualification processes for crushing consumables and wear parts
• Seasonal production planning aligned with wet-season access constraints

McLarty's extraction circuit is consistent with Peel Region construction material operations. Key engineering components include:

• Primary jaw crushing stage for coarse aggregate reduction
• Secondary and tertiary cone crushing for graded product specification
• Wet screening and classification to meet AS 2758 aggregate standards
• Settling pond systems for process water recovery and fines management
• Stockpile management infrastructure for segregated product grades

High physical-chemical precision is required to deliver consistent particle size distribution to civil contractors.

Operating within the ecologically sensitive Peel Region demands rigorous ESG compliance. Key sustainability obligations include:

• Progressive rehabilitation and landform reconstruction per Mining Rehabilitation Fund (MRF) obligations
• Sediment and erosion control plans (SECP) active during all rainfall events
• Fines and slurry containment via engineered settling ponds — functionally analogous to tailings storage facilities
• Biodiversity offset management for Banksia woodland and wetland buffers
• Dust suppression programs compliant with DER air quality guidelines
