Jurien Gypsum

The Jurien Bay Lime Sand Project (M70/307) is situated approximately 4 km north of Jurien Bay township, within the Shire of Dandaragan, Western Australia's Wheatbelt coastal fringe. The terrain is characterised by low-relief aeolian limestone ridges and coastal dune systems — a geomorphology that simplifies bulk earthmoving but demands precise stripping ratios to preserve near-surface calcareous deposits. Shallow water tables and sandy overburden minimise pre-strip complexity while increasing dust and erosion management obligations across the operational footprint.

Active extraction under operating status confirms continuous diesel-driven fleet deployment — front-end loaders, scrapers and haul trucks sustaining production cycles. Fuel logistics represent a critical OPEX vector given the site's remoteness from Perth (~220 km south). Key B2B operational dependencies include:

• Diesel supply chain via coastal road corridors (Brand Highway / Indian Ocean Drive)
• Mobile crushing and screening units requiring grid or genset power
• DIDO workforce rotation from Jurien Bay township
• Bulk product dispatch to agricultural lime markets across WA

Limesand operations at Jurien Bay employ a dry beneficiation circuit — mechanical screening and air classification rather than wet flotation — reflecting the high-purity, low-silica nature of coastal aeolian deposits. Critical engineering parameters include:

• Primary screening at particle size fractions suited for agricultural lime application
• Low-energy comminution due to friable carbonate matrix
• Dust suppression systems mandatory across all transfer and loading points
• No confirmed heavy grinding mill circuit — product quality managed via selective extraction

The project operates under EPA Western Australia environmental assessment obligations, with formal proposals lodged by Westdeen Holdings Pty Ltd confirming regulatory scrutiny. ESG priorities for B2B procurement engagement include:

• Aboriginal Heritage compliance under WA Aboriginal Heritage Act — Shire of Dandaragan protocols apply
• Rehabilitation and dune restoration commitments post-extraction
• Alignment with Noongar Country land stewardship expectations
• Agricultural lime supply supporting WA's soil acidification remediation — a measurable sustainability value chain outcome
