Catalano

Project Logistics & B2B Overview

Geographic Location and Topography

The Clarke Walpole / Catalano operation is situated within the South West Mining Field of Western Australia, a region characterised by dense jarrah and marri forest ecosystems. Terrain management demands rigorous Phytophthora cinnamomi (Dieback) control protocols, including mandatory hygiene stations, vehicle wash-down procedures, and restricted access corridors to prevent pathogen spread across ecologically sensitive zones adjacent to the extraction footprint.

• Dense native bushland surrounding the operational boundary
• Mandatory Dieback hygiene checkpoints at all site entry/exit points
• Proximity to South West WA biodiversity hotspot corridors

B2B Lifecycle and Operations

Operating under active production status, this construction materials quarry supplies aggregates, road base, and crushed rock to regional civil and infrastructure markets. Continuous operations rely on high-volume diesel consumption across drilling rigs, loaders, and haul trucks, with dependency on stable grid or substation power infrastructure to sustain crushing and screening circuits on extended operational schedules.

• Primary commodity: construction aggregates and road base materials
• Diesel-intensive mobile fleet for extraction and haulage cycles
• Power substation dependency for fixed plant processing continuity

Engineering and Extraction Infrastructure

The site's processing circuit integrates multi-stage crushing and screening plants linked by a network of heavy-duty conveyor belt systems that transfer crushed material between primary, secondary, and tertiary processing nodes. This conveyor-centric architecture minimises haul distances, reduces diesel burn on short-cycle movements, and enables precise product segregation by gradation specification for civil construction compliance.

• Primary jaw crusher feeding secondary cone/impact crusher stages
• Conveyor network for inter-stage material transfer and stockpile loading
• Vibrating screen decks for multi-fraction product classification

ESG, Value Chain and Sustainability

As a construction materials quarry, the site's ESG framework centres on progressive rehabilitation and sediment/runoff management rather than conventional tailings impoundments. Overburden and fines are managed through engineered waste rock and fines containment bunds, with proactive landform rehabilitation scheduled in parallel with extraction progression. Strict Dieback management and native vegetation offsets underpin the site's environmental licence conditions under Western Australian DER/DWER frameworks.

• Progressive quarry face rehabilitation concurrent with active extraction
• Sediment control bunds and stormwater diversion infrastructure
• Dieback management plan integrated into site environmental management system
• Native vegetation clearing offsets per DWER approval conditions
