Lake Deborah Salt

Lake Deborah is situated within the Yilgarn Mineral Field, Wheatbelt Region of Western Australia, approximately 350 km northeast of Perth. The site occupies a shallow, ephemeral salt lake system characteristic of the Yilgarn Craton's ancient peneplain. This remote positioning creates extended supply lines for consumables, reagents, and heavy equipment. The flat lacustrine topography facilitates surface harvesting operations but amplifies exposure to seasonal inundation risk, directly impacting operational scheduling and logistics planning cycles.

Lake Deborah operates under WA Salt Koolyanobbing Pty Ltd, a subsidiary of The WA Salt Group, in active production status. The operation supplies construction-grade and industrial salt commodities to domestic and export markets via dedicated order channels. B2B procurement is managed through:

• Export logistics: [email protected]

DIDO rosters are the primary workforce mobilisation model given the site's remoteness from Perth's labour pool.

Salt extraction at Lake Deborah relies on solar evaporation harvesting circuits rather than conventional comminution. Key infrastructure elements include:

• Crystallisation and concentration pond networks
• Mechanical harvesting equipment (scrapers, haul units)
• Washing and grading plant for product specification compliance
• Stockpile and load-out facilities for road/rail transfer

Physico-chemical control of brine concentration and product purity is critical to meeting construction materials and industrial-grade specifications.

The solar evaporation process inherently delivers a low direct-emission extraction model, aligning with Scope 1 decarbonisation targets. Key ESG considerations include:

• Minimal blasting or diesel-intensive comminution — reduced carbon intensity per tonne
• Potential integration of solar-assisted site power for processing and camp loads
• Water stewardship via closed-loop brine management
• Land rehabilitation obligations under WA DMP tenure conditions

Export channel diversification supports regional economic value retention across the Wheatbelt corridor.
