Wallis Witchcliffe /Silverthorne

Project Logistics & B2B Overview

Geographic Location and Topography

Wallis Witchcliffe/Silverthorne is situated in the South West region of Western Australia, near Witchcliffe in the Margaret River sub-region — a landscape characterised by lateritic profiles, karst-adjacent geology and dense jarrah-marri woodland corridors. Proximity to protected ecological buffers (including wetland systems feeding the Blackwood River catchment) demands rigorous surface hydrological management. Stormwater diversion bunds, sediment retention basins and turbidity monitoring are operationally non-negotiable at this latitude.

B2B Lifecycle and Operations

Currently classified as Operating, this construction materials quarry supplies aggregate, road base and/or sand products to regional civil and infrastructure markets. The South West corridor — servicing Busselton, Margaret River and Augusta — sustains consistent demand. B2B vendors must account for:

• Limited on-site mechanical infrastructure typical of mid-tier quarries
• Local workshop dependency for crusher and screen maintenance
• Acute exposure to unplanned downtime without contracted mobile service providers
• Seasonal demand peaks tied to regional road construction programs

Engineering and Extraction Infrastructure

Construction materials operations at this scale typically deploy a primary jaw or impact crusher circuit feeding secondary cone or VSI stages for graded aggregate production. Key engineering considerations include:

• Wear-part consumption rates on crusher liners and screen meshes
• Dust suppression systems compliant with DER/DWER licensing conditions
• Wash plant or scrubbing circuits if clay-bound material is present
• Weighbridge calibration and load-out logistics for road transport compliance

ESG, Value Chain and Sustainability

South West WA quarries face increasing ESG scrutiny from local government and community stakeholders. Decarbonisation pathways relevant to this operation include:

• Transition to solar-assisted site power for ancillary loads (lighting, offices, pumps)
• Diesel fleet optimisation or hybrid light vehicle deployment
• Rehabilitation bonding and progressive landform restoration per DMIRS requirements
• Native vegetation offset programs aligned with regional biodiversity corridors
