Yalyalup

Yalyalup is situated within the South West region of Western Australia, near Busselton, embedded in the Swan Coastal Plain's low-relief aeolian dune system. The operation sits in close proximity to Geographe Bay coastal ecosystems and Ramsar-adjacent wetland buffers, imposing strict hydrological surface management obligations. Shallow water tables and seasonal drainage patterns demand engineered bunding, diversion drains, and continuous groundwater monitoring to prevent saline intrusion into adjacent conservation corridors.

Yalyalup operates as a continuous 24/7 production asset under Doral Mineral Sands, targeting ilmenite, zircon, leucoxene, and rutile concentrate streams. Operational continuity is underpinned by:

• Diesel-intensive mobile fleet — scrapers, dozers, and front-end loaders running uninterrupted shift cycles
• Dependency on regional Western Power grid subestations for wet concentrator plant (WCP) and mineral separation plant (MSP) loads
• DIDO workforce rotation coordinated through Bunbury/Busselton corridors
• Iwatani Corporation (Japan) offtake integration ensuring downstream titanium feedstock supply chain stability

The processing circuit at Yalyalup follows a dual-stage HMS beneficiation architecture:

• Primary wet concentration — spiral classifier banks and hydrosizers processing slurried feed from the mining unit
• Mineral separation plant (MSP) — electrostatic, magnetic, and gravity separation circuits demanding precise physico-chemical conditioning (pH control, surface chemistry modifiers)
• Flotation-assisted zircon upgrading requiring reagent dosing systems and froth management infrastructure
• High-voltage electrostatic separators with strict temperature and humidity tolerances

Doral's Yalyalup operation is governed by a proactive rehabilitation-concurrent mining model, a regulatory condition of its Mining Proposal under DMIRS. Key ESG pillars include:

• Tailings storage facilities (TSF) — engineered dry-stack and slurry containment cells with leachate collection and liner systems
• Progressive landform reconstruction and native Banksia woodland revegetation aligned with DER-approved Mine Closure Plans
• Groundwater quality monitoring bores across the extraction footprint
• Community liaison managed directly via dedicated CRO contact ([email protected]), reflecting Iwatani's corporate ESG governance framework
