Shark Bay Shell Grit

Sandy Point Shellgrit is situated within the South West Mining Field of Western Australia's Wheatbelt region — a low-relief, coastal-proximate landscape characterised by shallow unconsolidated sedimentary sequences and aeolian shell deposits. The flat to gently undulating terrain minimises overburden stripping ratios, enabling high-efficiency surface extraction. Proximity to coastal inlets facilitates direct access to biogenic carbonate accumulations. Low topographic relief reduces earthmoving complexity but demands precise water table management during wet-season operations.

As an operating quarry, Sandy Point Shellgrit functions within a DIDO (Drive-In Drive-Out) labour model typical of Wheatbelt regional operations, drawing workforce from nearby centres including Bunbury and Mandurah. No FIFO camp infrastructure has been identified on-site. Supply chain integration targets:

• Bulk haulage via regional road networks to agricultural and construction end-users
• Seasonal demand cycles aligned with WA grain-belt soil amendment programs
• Short-haul logistics to coastal dispatch points for marine or port-based offtake

The deposit comprises biogenic limesand and shellgrit — high-calcium carbonate material requiring minimal comminution. Primary processing involves:

• Mechanical screening and wet or dry classification to achieve particle size specifications
• No conventional crush-and-grind circuit required — material friability allows direct scalping
• Stockpile management for moisture control and product segregation by grade
• Quality parameters governed by CaCO₃ purity thresholds for agricultural lime and construction fill applications

Absence of hard-rock processing significantly reduces CAPEX and energy intensity per tonne.

Limesand operations carry an inherently low carbon intensity profile relative to hard-rock mining — reduced blasting, minimal crushing energy, and short haul distances compress Scope 1 emissions. Key ESG considerations include:

• Land rehabilitation obligations under WA DMP/DMIRS tenure conditions post-extraction
• Coastal and wetland buffer compliance given proximity to sensitive marine sediment systems
• Agricultural lime supply chain supports regional soil carbon sequestration programs — an indirect ESG value proposition for downstream buyers
• Potential alignment with WA Government's regional decarbonisation and food security frameworks
