Parker Range (Mount Caudan)

Mt Caudan is situated within the Parker Range project area in the Yilgarn Mineral Field, Wheatbelt Region of Western Australia. The terrain is characterised by low-relief, laterite-capped mesa formations typical of the Yilgarn Craton, with shallow overburden profiles overlying high-grade iron ore bodies. This flat-to-undulating topography facilitates large-scale bulk earthworks and optimises haul road geometry, reducing cycle times for heavy mining equipment during mass movement operations.

Following acquisition by Yilgarn Iron Investments Pty Ltd (YII) from Mineral Resources (MinRes) effective 30 June 2025, Mt Caudan operates as part of the integrated Yilgarn Hub DSO supply chain. The site demands continuous B2B engagement across:

• On-site mechanical workshops for heavy mobile equipment (HME) servicing to minimise costly unplanned downtime
• Tyre management and GET (Ground Engaging Tools) supply contracts
• Fuel logistics and bulk consumables procurement
• Drill and blast contractor services for ore exposure

Mt Caudan's DSO operation relies on a streamlined run-of-mine (ROM) processing circuit incorporating crushing, screening, and materials handling systems. Key infrastructure elements include:

• Heavy-duty conveyor systems managing high-tonnage ore transfer from ROM pad to product stockpiles
• Mobile crushing and screening plant for size classification
• Sealed haul roads engineered for 90-tonne payload articulated trucks
• Weighbridge and sampling stations for product quality assurance

Mt Caudan's operational licence is contingent on rigorous tailings and waste rock management protocols aligned with Western Australian DMIRS requirements. Proactive rehabilitation commitments include:

• Progressive landform rehabilitation concurrent with active mining phases
• Dust suppression programs across haul corridors and ROM areas
• Topsoil salvage and native seed bank preservation for post-mining revegetation
• Water management plans addressing ephemeral drainage protection in the Wheatbelt catchment
