Onslow Iron

Project Logistics & B2B Overview

Geographic Location and Topography

Old Onslow is situated within the Ashburton Municipal Function zone of Western Australia's Pilbara region, a landscape defined by arid spinifex plains, ancient sedimentary formations, and extreme thermal exposure. Ambient temperatures routinely exceed 45°C during summer months, imposing critical thermal stress on all surface-deployed equipment. The site's proximity to the Ashburton River corridor introduces seasonal flood-risk variables that directly affect haul road integrity and site accessibility planning for B2B contractors.

B2B Lifecycle and Operations

Operating status confirms active extraction of construction materials, likely targeting alluvial gravels, calcrete, or hard-rock aggregate consistent with Pilbara geological profiles. Operational continuity depends on FIFO rotational rosters, typically structured on 2:1 or 3:1 swing cycles from Onslow or Paraburdoo hubs. Key B2B service requirements include:

• Camp catering and accommodation management
• Fuel logistics and bulk consumables supply
• Workforce transport coordination (charter aviation or road)
• Maintenance crew scheduling aligned to roster cycles

Engineering and Extraction Infrastructure

Construction material quarries in this corridor typically deploy conveyor-intensive processing circuits for aggregate sizing, screening, and stockpile management. Thermal management of drive motors and belt systems is non-negotiable given ambient heat loads. Critical engineering considerations include:

• Heat-rated conveyor belting and lagging compounds
• Crusher feed systems with variable-speed drives
• Dust suppression networks across transfer points
• Haul fleet with engine thermal monitoring systems

ESG, Value Chain and Sustainability

Pilbara construction material operations face increasing pressure to align with ESG decarbonisation targets under Western Australia's state energy transition framework. For a site of this profile, viable pathways include:

• Hybrid or solar-diesel microgrid power for processing plant loads
• Transition to electric light vehicles (ELV) for site personnel movement
• Water recycling circuits within wash and screening plants
• Scope 3 reporting integration for downstream aggregate supply chains
