D'Entrecasteaux

Point D'Entrecasteaux is situated within the South West region of Western Australia, a coastal-adjacent zone characterised by low-relief terrain and calcareous dune systems. The site's proximity to protected coastal ecosystems — including Banksia woodlands and sensitive wetland corridors — demands rigorous surface hydrological management. Stormwater diversion and sediment control infrastructure are operationally critical to prevent leachate migration into adjacent conservation buffers and groundwater-dependent ecosystems.

The operation extracts limestone and limesand, commodities supplying agricultural lime, construction aggregate, and coastal engineering markets across South West WA. As an active operating site, procurement cycles for consumables — including wear liners, conveyor belting, and blasting accessories — are continuous. The acute need for local mechanical workshop support is paramount; remote sourcing of heavy equipment repairs introduces unacceptable downtime risk for a surface extraction operation dependent on high-volume throughput schedules.

Limesand and limestone extraction relies on high-capacity conveyor systems to transfer friable and granular material from the extraction face to processing and stockpile zones. Complex multi-stage conveyor networks require precision belt tensioning, idler maintenance, and transfer chute management to sustain throughput efficiency. Dust suppression systems are integral given the fine-particle nature of limesand. Mobile crushing and screening plant configurations are typical for this commodity class, enabling flexible product gradation to meet diverse civil and agricultural specifications.

Operating within a sensitive South West coastal corridor mandates a proactive rehabilitation programme aligned with DMP and DWER regulatory frameworks. While limesand operations generate minimal conventional tailings, overburden and fines management facilities must comply with strict containment and progressive rehabilitation standards. Revegetation with endemic Banksia and Acacia species is standard practice. ESG-aligned vendors supplying dust suppression reagents, erosion control matting, and native seed propagation services hold a competitive advantage in procurement engagement at this site.
