Central Gypsum

Lake Cowan Gypsum is situated within the Dundas Mineral Field, Goldfields-Esperance Region, Western Australia — a hyper-arid playa lake environment characterised by flat, saline terrain and extreme thermal exposure. Summer ambient temperatures routinely exceed 45°C, imposing critical thermal stress on mobile plant and heavy equipment. Effective heat management protocols — including scheduled cool-down cycles, thermal-rated hydraulic fluids, and shaded maintenance bays — are non-negotiable operational requirements for sustained uptime in this environment.

Operated by Central Gypsum (formerly Whitfield Minerals), the site maintains active operating status, supplying industrial-grade gypsum to construction and agricultural markets. The remote Goldfields location creates acute dependency on:

• Local mechanical workshops for rapid turnaround on plant breakdowns
• Mobile field service contractors capable of same-day response
• Preventive maintenance contracts to minimise unplanned downtime
• Spare parts pre-positioning strategies for critical components

Unplanned stoppages in this corridor carry disproportionate cost penalties due to supply chain distances.

Surface gypsum extraction at Lake Cowan relies on bulk material handling systems where conveyor belt infrastructure plays a central role in transferring raw gypsum from the pit face to processing and stockpile areas. Key engineering considerations include:

• Heat-resistant conveyor belting rated for extreme ambient conditions
• Dust suppression systems integrated along transfer points
• Screening and sizing plant for product specification compliance
• Haul road maintenance under high-salinity, expansive clay subgrade conditions

Operating within the Goldfields-Esperance Region, Central Gypsum is subject to Western Australia's Aboriginal Heritage Act compliance obligations, requiring active heritage surveys and clearance protocols prior to any ground disturbance. B2B procurement priorities increasingly favour:

• Partnerships with Indigenous-owned enterprises for site services and labour
• Registered RAP (Reconciliation Action Plan) alignment for tier-1 suppliers
• Minimal footprint extraction methods consistent with playa lake ecosystem sensitivity
• Dust and salinity runoff controls as core environmental compliance metrics
