WA Salt Koolyanobbing

Lake Deborah Pond is situated within the Yilgarn Mineral Field, Wheatbelt Region of Western Australia — a vast, semi-arid playa lake system characteristic of the ancient Yilgarn Craton. The terrain is hyper-flat saline lakebed, with minimal elevation gradient, which is operationally advantageous for brine containment and solar evaporation pond construction. Seasonal rainfall variability and high evaporation rates (exceeding 2,500 mm/year) define the hydrogeological regime, directly governing harvest cycle scheduling and brine concentration management.

Operations are managed by WA Salt Koolyanobbing Pty Ltd under The WA Salt Group umbrella. The production model relies on a solar evaporation cycle — brine is concentrated across staged pond systems before mechanical harvesting. Diesel-powered harvesting equipment (scrapers, front-end loaders, haul trucks) drives continuous fuel consumption during peak harvest windows. Electrical infrastructure demand is moderate compared to hard-rock operations, but auxiliary processing and water management systems maintain consistent energy draw throughout the operational season.

Unlike conventional hard-rock circuits, Lake Deborah employs a wet harvesting and washing circuit rather than comminution or flotation. Key engineering components include:

• Staged evaporation ponds for progressive NaCl concentration
• Mechanical harvesters and conveyor-fed wash plants
• Brine recirculation and bittern management systems
• Stockpile management for bulk and packaged-grade salt segregation
• Road-load-out infrastructure for long-haul transport to Perth

Product quality control targets food-grade and industrial-grade NaCl purity specifications.

Operating within the Wheatbelt, the project intersects with Aboriginal Heritage obligations under the WA Aboriginal Heritage Act — site clearance and ongoing operational compliance are non-negotiable B2B requirements. The WA Salt Group's supply chain extends to retail and industrial markets via the North Coogee facility, supporting local value-add processing. Sustainability priorities include:

• Minimal groundwater extraction versus conventional mining
• Low-disturbance footprint relative to hard-rock operations
• Heritage survey compliance prior to pond expansion
• Engagement pathways with local Noongar custodians
