Manypeaks Lime

The Homestead Manypeaks Lime operation is situated within the Manypeaks locality, Great Southern region of Western Australia, approximately 50–60 km east of Albany. The terrain is characterised by low-relief coastal plain transitioning into granite-gneiss outcrops of the Stirling Range foothills. The shallow, undulating topography facilitates low strip-ratio open-cut extraction, minimising overburden handling costs. Proximity to the Southern Ocean introduces moderate wind and moisture variables that influence dust suppression protocols and haul road maintenance scheduling across the active quarry footprint.

WALCO operates Homestead Manypeaks as an active, continuous-supply quarry servicing the agricultural lime market across South West and Great Southern WA. The operation functions on a DIDO roster model, drawing workforce from Albany and surrounding townships, eliminating the need for permanent camp infrastructure. Key B2B supply chain outputs include:

• Agricultural limestone and limesand for soil pH correction
• Bulk road-train delivery to broadacre farming operations
• Contracted spreading services across the grain belt
• Direct farm-gate supply agreements with cropping enterprises

The quarry employs conventional drill-and-blast or rip-and-push extraction methods suited to the soft-to-medium hardness limestone and limesand deposits. Processing infrastructure includes:

• Primary jaw or impact crushing circuit for coarse limestone fractions
• Screening decks for particle size classification (agricultural grade)
• Limesand recovery via front-end loader and direct-load stockpiling
• On-site weighbridge for bulk dispatch compliance

No flotation circuit is required given the non-sulphide, carbonate-dominant ore body. Product quality targets minimum 85–90% CaCO₃ purity for agronomic efficacy.

WALCO's Manypeaks operation contributes to regional soil carbon sequestration indirectly by enabling lime-driven pH correction that improves pasture productivity and reduces synthetic fertiliser dependency. Identified ESG levers include:

• Short haul distances reducing fleet Scope 1 emissions per tonne delivered
• DIDO workforce model eliminating camp energy and water consumption
• Potential integration of renewable-powered crushing as grid access via Western Power's South West Interconnected System (SWIS) is available in the Albany corridor
• Rehabilitation obligations under WA DMP tenure conditions post-extraction
