Yanchep

Military Yanchep is situated within the South West Mining Field of Western Australia's Wheatbelt region, north of Perth along the coastal plain. The terrain is characterised by low-relief, flat-to-undulating limestone karst formations — a topographic profile that significantly simplifies bulk earthmoving operations and reduces stripping ratios. Shallow overburden depths typical of this corridor allow direct bench extraction with minimal pre-strip, optimising fleet utilisation and lowering cost-per-tonne benchmarks for dimension stone and limesand recovery.

The site operates under Mining Lease M70/1325, with PMR Quarries Pty Ltd trading as WA Limestone as the active operator, under the corporate umbrella of Schaffer Corporation Limited. The quarry maintains an Operating status, supplying construction-grade limestone and limesand to Perth metropolitan and regional markets. B2B procurement teams should note the parallel Adelaide Brighton Ltd tenure, currently in closure stage, which does not affect WA Limestone's active extraction footprint. Vendor engagement should be directed through DMPE-registered channels.

Dimension stone and limesand extraction at Military Yanchep relies on conventional drill-and-blast or mechanical ripping, followed by primary crushing and conveyor-fed screening circuits. The flat coastal plain geology enables efficient conveyor belt layouts with minimal elevation change, reducing mechanical stress on drive systems. However, abrasive limesand material accelerates belt wear and idler degradation, creating acute demand for:

• On-call mechanical workshops with conveyor maintenance capability
• Rapid-response spare parts supply for crushers and screening decks
• Mobile plant servicing to minimise unplanned downtime
• Dust suppression system maintenance in high-production periods

As a Schaffer Corporation-linked operation, Military Yanchep is subject to increasing ESG reporting pressure aligned with ASX-listed corporate governance standards. The site's flat topography and proximity to Perth's grid infrastructure create a viable pathway for:

• Solar hybrid power integration to offset diesel consumption in fixed plant
• Electric light vehicle (ELV) adoption for site logistics and personnel movement
• Progressive land rehabilitation commitments per DMPE closure planning frameworks
• Dust and groundwater monitoring as core environmental compliance metrics

Suppliers offering low-emission equipment solutions hold a competitive advantage in vendor qualification at this site.
