Newman Operations

Project Logistics & B2B Overview

Geographic Location and Topography

Newman Aggregate operates within the Peak Hill M.F. zone of the Pilbara region, Western Australia — one of the most geologically ancient and hydrologically stressed landscapes on Earth. The site sits within a semi-arid to arid climatic band where annual rainfall rarely exceeds 300 mm. Extreme thermal amplitude, ironstone-rich terrain, and episodic flash flooding define the operational envelope. Water sourcing for dust suppression and processing relies on bore infrastructure, making hydrological asset management a non-negotiable operational priority.

B2B Operational Cycle and Site Activity

As an operating quarry, Newman Aggregate supplies crushed rock and construction-grade aggregate to regional infrastructure projects across the Pilbara corridor. Operational continuity depends on:

• Diesel-powered mobile fleet (excavators, haul trucks, loaders) running extended shift cycles
• Dependence on grid or generator-backed power substations for crushing and screening plants
• Coordination with regional civil contractors and road construction supply chains
• Fuel logistics managed via Newman township supply nodes

Engineering and Extraction Infrastructure

The extraction circuit at Newman Aggregate is structured around primary jaw crushing followed by secondary and tertiary cone crushing stages to achieve graded aggregate specifications. Key engineering demands include:

• Vibrating screen decks for particle size classification (sub-base, road base, drainage aggregate)
• Dust suppression systems critical under Pilbara wind and heat conditions
• Wear-part replacement cycles accelerated by abrasive ironstone and quartzite lithologies
• Stockpile management aligned to project dispatch schedules

ESG, Value Chain and Sustainability

Construction material quarries in the Pilbara operate under Western Australian DMP/DMIRS regulatory frameworks, requiring progressive rehabilitation and dust/noise impact mitigation. For Newman Aggregate, ESG obligations include:

• Progressive landform rehabilitation of extracted benches per approved Mine Closure Plan
• Stormwater and sediment control structures to protect local drainage lines
• Minimal process water discharge — closed-loop dust suppression circuits preferred
• Biodiversity offset compliance within Pilbara's sensitive Mulla Mulla and Spinifex ecosystems
