Marandoo Mine

Marandoo Centre is situated within the West Pilbara Mineral Field, adjacent to Karijini National Park, approximately 35 km east of Tom Price, Western Australia. The terrain is characterised by extreme arid conditions, with annual rainfall below 300 mm and temperatures exceeding 45°C in summer. Water supply infrastructure — including bore fields and managed aquifer systems — is operationally critical. Any B2B supplier entering this environment must account for dust suppression, heat management, and water-efficient service delivery as non-negotiable baseline requirements.

Marandoo Centre operates as an active open-cut iron ore operation under Rio Tinto's Pilbara iron ore network, integrated into the broader Hamersley Iron supply chain. The site demands continuous availability of heavy mobile equipment (HME) maintenance services — including on-site mechanical workshops — to prevent costly unplanned downtime on haul trucks, excavators, and drills. B2B vendors must demonstrate rapid response capability, local parts inventory, and certified technicians aligned with Rio Tinto's contractor management standards.

Material handling at Marandoo Centre relies on a high-throughput system integrating drill-and-blast, load-and-haul, and conveyor belt infrastructure feeding primary and secondary crushing circuits. The conveyor network is subject to intense abrasive wear from high-silica iron ore, requiring specialist belt maintenance, idler replacement programs, and real-time tension monitoring. Ore is transferred via rail to the port of Dampier or Cape Lambert. Engineering suppliers must be qualified for Rio Tinto's stringent mechanical and structural compliance frameworks applicable across all Pilbara fixed-plant assets.

Marandoo Centre sits within a zone of significant cultural sensitivity, requiring strict Aboriginal Heritage compliance under the Western Australian Aboriginal Heritage Act. Rio Tinto mandates engagement with Traditional Owner groups — including the Yinhawangka people — and actively prioritises procurement from Indigenous-owned enterprises through its Reconciliation Action Plan. B2B partners are expected to demonstrate verifiable Indigenous engagement strategies. Environmental obligations include rehabilitation bonding, groundwater monitoring, and biodiversity offset programs aligned with Rio Tinto's 2030 sustainability targets.
