Billiard South

The Billiard deposit (inclusive of the Pocket and Billiard South zones) is situated within the West Pilbara Mineral Field, Pilbara Region, Western Australia. The terrain is characterised by ironstone mesa formations, spinifex-dominated plains, and extreme thermal gradients exceeding 45°C in summer. Operational water supply — sourced from licensed borefield allocations — is a critical survival constraint for dust suppression, personnel welfare, and process continuity in this hyper-arid environment.

Billiard operates as an active DSO (Direct Shipping Ore) open-cut mine integrated into Rio Tinto's broader Hamersley Iron production system. Key B2B operational dependencies include:

• Continuous diesel consumption across drill-and-blast, load-and-haul fleets operating 24/7 rotational shifts
• Reliance on high-voltage substation infrastructure feeding ancillary processing and camp loads
• FIFO workforce rotation via regional aerodromes under Rio Tinto's managed logistics framework
• Ore haulage integrated into the Hamersley Iron heavy-haul rail corridor to Dampier/Cape Lambert

As a DSO operation, Billiard's processing circuit is comparatively lean; however, engineering demands remain significant:

• Primary crushing and screening circuits for lump/fines product separation
• Wet screening or beneficiation modules to meet Fe grade and contaminant (Al₂O₃, SiO₂, P) specifications
• Tailings and ROM pad management under strict geotechnical protocols
• Heavy mobile equipment (CAT 793/789 class trucks, hydraulic shovels) demanding high-cycle maintenance contracts

Rio Tinto's ESG obligations at Billiard are governed by stringent Western Australian and federal frameworks:

• Aboriginal Heritage compliance under the WA Aboriginal Heritage Act — site surveys and clearance protocols are non-negotiable pre-disturbance requirements
• Preferential procurement targeting Indigenous-owned enterprises aligned with Rio Tinto's Reconciliation Action Plan
• Biodiversity offset and land rehabilitation commitments embedded in the mine closure plan
• Scope 1 emissions reporting and decarbonisation pathway targets per Rio Tinto's 2030 climate commitments
