Ludlow Myalup Limestone

The Ludlow Myalup operation is situated on Lots 4 and 5, Deposited Plan 15419, Ludlow Road, Myalup, within the Shire of Harvey, South West Western Australia. The site lies within the Swan Coastal Plain, characterised by low-relief sandy terrain interbedded with Tamala Limestone and aeolian limesand deposits. Proximity to the Ludlow State Forest demands strict Phytophthora cinnamomi (Dieback) hygiene protocols, including vehicle wash-down stations and declared hygiene zones to prevent pathogen spread across the dense native tuart and jarrah vegetation corridors.

Continuous extraction has been conducted by B&J Catalano Pty Ltd. since 2009, with MGM Limestone Pty Ltd. holding 100% ownership of the broader Myalup/MGM project targeting limestone, limesand, and cmat products. The operation services regional construction, agriculture (soil amelioration), and civil infrastructure markets across South West WA. Given the DIDO-dominant workforce model from Bunbury and Harvey townships, rotating roster management is critical for productivity continuity, with no permanent camp infrastructure currently confirmed on-site.

The deposit is worked via open-cut benching with drill-and-blast or rip-and-push methodology suited to the soft-to-medium Tamala Limestone formation. Primary crushing circuits process run-of-mine material into graded aggregate, agricultural lime, and limesand fractions. No flotation plant is required given the sedimentary carbonate mineralogy; however, particle size classification and moisture-content control are critical quality parameters for agricultural-grade calcium carbonate product specifications. Secondary screening and stockpile management at the Picton satellite site supports downstream distribution logistics.

Operations within the Shire of Harvey require compliance with Aboriginal Heritage Act (WA) obligations, necessitating due-diligence surveys prior to any new disturbance footprint expansion. Land rehabilitation bonds and progressive mine closure planning are mandated under DMIRS conditions. B2B procurement partners should note the increasing regional expectation for Indigenous procurement commitments and Noongar Country engagement protocols. Dust suppression, native vegetation offset programs, and hydrological impact monitoring of the superficial aquifer system constitute the primary environmental management obligations for this operation.
