Myalup MGM

Project Logistics & B2B Overview

Geographic Location and Topography

The Forrest Myalup operation is situated on Lot 1794 Finn Road, Myalup, within Western Australia's South West region — a low-lying coastal plain characterised by sandy soils and seasonal wetlands. The terrain presents significant haul road vulnerability during winter rainfall events, where saturated access tracks generate heavy mud accumulation, directly impacting truck cycle times and payload efficiency. Proactive road sheeting, drainage culvert maintenance, and load restrictions during peak wet periods are operationally critical for uninterrupted limestone and sand extraction.

B2B Lifecycle and Operations

Currently classified as Operating, the site functions as a dual-commodity quarry supplying limestone and construction sand to regional civil and infrastructure markets. The project is 100% held by MGM Limestone Pty Ltd, with MGM Bulk Pty Ltd acting as the operational proponent. Given the site's proximity to Bunbury and Perth's southern corridor, workforce deployment follows DIDO rotational rosters rather than remote FIFO camp models, reducing accommodation overhead while demanding strict fatigue management protocols for daily commuting personnel.

Engineering and Extraction Infrastructure

Limestone and sand extraction at Myalup relies on open-cut quarrying methods, integrating drill-and-blast or ripping sequences depending on material hardness. Downstream processing demands conveyor-intensive material handling — multi-stage belt systems transfer crushed limestone from primary crushers through screening decks to stockpile zones. Conveyor alignment, belt tension management, and transfer point dust suppression are critical engineering priorities. Sand extraction circuits typically incorporate:

• Wet screening and classification units
• Hydrocyclone separation for fines control
• Radial stacker conveyors for product segregation
• Weighbridge-integrated dispatch systems

ESG, Value Chain and Sustainability

As ESG scrutiny intensifies across Western Australian quarrying operations, Myalup-scale projects face mounting pressure to demonstrate decarbonisation pathways. Key sustainability levers applicable to this operation include:

• Deployment of solar-assisted power generation for processing plant loads
• Transition to electric or hybrid light vehicles for site personnel movement
• Progressive rehabilitation and native vegetation restoration post-extraction
• Dust and noise monitoring aligned with DER/DWER compliance frameworks
• Water recycling within wet processing circuits to minimise groundwater drawdown

Alignment with WA Government construction material supply chains positions the project within broader regional infrastructure ESG reporting obligations.
