Lake Goorly Gypsum Mine

Lake Goorly is situated within the Wheatbelt region of Western Australia, approximately 280–300 km northeast of Perth, near the township of Kalannie. The deposit occupies a shallow playa lake system — a classic evaporite environment characteristic of the WA inland plateau. This remote positioning creates extended supply chain lead times for consumables, mechanical parts, and specialist labour, placing acute pressure on procurement planning and inventory buffering at site level.

LGC operates as a owner-operator SME, extracting and supplying agricultural-grade gypsum to the broadacre farming sector across WA. The operational model is lean and logistics-dependent. Key B2B considerations include:

• Local mechanical workshop access is critical — nearest heavy equipment service centres are in Dalwallinu or Moora, 80–120 km away.
• Unplanned downtime on scrapers or haul trucks carries disproportionate cost at this scale.
• Seasonal extraction windows align with dry-season lake bed conditions (typically April–October).

Gypsum extraction at Lake Goorly follows a surface scraper and bulk-load methodology — no conventional drill-and-blast circuit. Processing is minimal: primary crushing and screening to achieve agricultural particle size specification. Unlike sulphide operations, there is no flotation plant or reagent circuit. Infrastructure demands centre on:

• Grader and scraper fleet maintenance under abrasive saline conditions.
• Stockpile management on lake-edge hardstand.
• Road-train loading and dispatch logistics to farm-gate customers.

As a playa lake evaporite operation, Lake Goorly presents a low-disturbance extraction profile relative to hard-rock mining. No conventional tailings storage facility (TSF) is required. ESG obligations focus on:

• Progressive rehabilitation of scraped lake-bed surfaces per DMP/DMIRS tenure conditions.
• Dust suppression management across exposed lake sediments.
• Hydrological integrity of the playa system post-extraction.
• Compliance with WA Mining Act 1978 small-operator rehabilitation bond requirements.
