Warradarge Silica Mine

Warradarge Silica Mine is situated in the South West Land Division of Western Australia's Mid-West region, approximately 350 km north of Perth. This distance creates significant logistical pressure on supply chains, as critical consumables, replacement parts, and specialist contractors must be mobilised from Perth or Geraldton. The terrain is characterised by low-relief coastal plain geology, with near-surface silica sand deposits requiring minimal overburden removal but demanding precise grade control across wide extraction footprints.

The operation is classified as active/operating, placing it in a sustained procurement cycle requiring continuous vendor engagement. Key B2B priorities include:

• Mobile plant maintenance contracts for scrapers, dozers, and front-end loaders
• Local mechanical workshop access to minimise costly unplanned downtime
• Reagent and chemical supply for wet processing circuits
• Tyre management and GET (Ground Engaging Tools) replenishment programs

The absence of a nearby industrial hub makes pre-positioned spare parts inventory a critical operational requirement.

Silica sand extraction at Warradarge relies on bulk material handling systems, including an intensive network of conveyor belts transferring raw feed from the pit face to wet scrubbing and classification circuits. Key engineering considerations include:

• Belt alignment, tensioning, and idler maintenance under abrasive silica conditions
• Slurry pump wear management in hydrocyclone circuits
• Stockpile management for product specification compliance
• Dust suppression systems across transfer points

Conveyor system reliability is directly linked to production continuity and export scheduling.

Operating in the Mid-West region requires strict adherence to Aboriginal Heritage Act compliance (WA AHA 1972, transitioning under AHA 2021), with mandatory ethnographic surveys and Section 18 consents prior to ground disturbance. B2B procurement strategies increasingly prioritise:

• Engagement with Aboriginal-owned enterprises for civil, catering, and labour hire services
• Rehabilitation bonding and progressive landform restoration
• Water management plans aligned with DWER licensing conditions
• Carbon footprint reporting for downstream industrial buyers

Heritage alignment is now a commercial differentiator in silica sand export markets.
