Beaufort River Dolomite

Beaufort River Dolomite is situated near Kojonup, Western Australia, approximately 280–320 km southeast of Perth in the Great Southern region. This remote positioning creates extended supply chain lead times for consumables, equipment parts, and reagents. The site sits within the undulating agricultural terrain of the Beaufort River catchment, characterised by shallow dolomitic limestone outcrops. Road access depends on rural arterial routes, making logistics planning and inventory buffer management critical operational variables for any B2B vendor or contractor.

The operation is classified as Operating status under Western Australia's mineral tenement framework, producing limestone and limesand — key inputs for agricultural lime, soil pH correction, and construction aggregate markets. As a small-to-mid scale quarry, the site relies on diesel-powered mobile plant (excavators, loaders, haul trucks) for extraction and processing. Continuous diesel consumption creates recurring B2B procurement cycles for fuel supply, lubricants, and mechanical servicing. Energy dependency on diesel generation rather than grid substations is the dominant operational cost driver.

The primary extraction circuit involves drill-and-blast or rip-and-push methodology suited to shallow dolomitic limestone formations, followed by primary crushing and screening. Limesand product lines require controlled particle size distribution (PSD) to meet agricultural and industrial specifications. Key engineering requirements include:

• Primary jaw or impact crusher for coarse reduction
• Vibrating screen decks for PSD classification
• Dust suppression systems (water cart dependency)
• Mobile conveying or front-end loader stockpile management
• Calcium carbonate (CaCO₃) and MgCO₃ quality assurance sampling

Operating within WA's Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) framework, the site is subject to progressive rehabilitation obligations under the Mining Rehabilitation Fund (MRF). Key ESG considerations include:

• Proactive landform rehabilitation of extracted benches post-quarrying
• Sediment and runoff controls protecting the Beaufort River catchment
• Minimal tailings generation (limestone quarry); primary waste is overburden
• Dust management compliance in proximity to agricultural land
• Membership in Lime WA Inc. signals alignment with industry ESG benchmarks
