Old Coast Herron

Old Coast Herron is situated within the Peel Region of Western Australia, a coastal-plain corridor characterised by low-relief Quaternary limestone and limesand deposits. The site lies in proximity to the Peel-Harvey estuarine ecosystem, a Ramsar-listed wetland system, imposing strict surface-water management obligations. Operators must maintain engineered bunding and sediment control infrastructure to prevent turbid runoff from reaching sensitive hydrological receptors during high-intensity rainfall events common to the South West coastal plain.

As an operating quarry, Old Coast Herron sustains continuous demand for mobile plant maintenance, consumables supply, and haulage contracting. The absence of publicly listed operators creates a critical gap for local mechanical workshops in the Mandurah–Murray corridor to position themselves as preferred vendors. Unplanned downtime on primary excavators and articulated dump trucks carries disproportionate cost in single-commodity limestone operations. B2B suppliers offering rapid-response field service within a 60 km radius hold a decisive competitive advantage.

Limesand and limestone extraction at this site relies on ripping and dozing rather than drill-and-blast, given the unconsolidated to semi-consolidated nature of Peel Region coastal deposits. Primary sizing is achieved through jaw or impact crushing circuits, with downstream screening to meet grading specifications for agricultural lime, construction fill, and road base. Physico-chemical quality control — including CaCO₃ purity assay and moisture content management — is critical for product certification. Dust suppression systems and haul-road stabilisation are standard engineering requirements on-site.

Limestone quarrying in the Peel Region operates under increasing ESG scrutiny tied to proximity to protected coastal wetlands and biodiversity corridors. Progressive rehabilitation obligations under WA's Mining Act require concurrent landform restoration. Decarbonisation pathways relevant to this operation include transitioning light vehicles to battery-electric platforms and integrating rooftop or ground-mounted solar to offset grid consumption in crushing and screening circuits. Agricultural lime supply chains also contribute measurable Scope 3 carbon sequestration credits through soil carbon enhancement, a growing value-chain differentiator.
