Myalup Limestone

Project Logistics & B2B Overview

Geographic Location and Topography

Harris Myalup is situated within the South West region of Western Australia, a zone characterized by low-relief coastal plains and proximity to the Myalup wetlands system. Operations must navigate strict hydrological surface management protocols given the adjacency to Ramsar-listed and environmentally sensitive ecosystems. Stormwater diversion, sediment control bunding, and groundwater monitoring are non-negotiable compliance requirements for any active extraction footprint in this corridor.

B2B Lifecycle and Operations

As an operating construction materials site, Harris Myalup supports regional civil and infrastructure supply chains across the South West. Operational continuity depends on:

• Diesel-powered mobile fleet for extraction, haulage, and loading cycles
• Grid or substation-fed fixed plant infrastructure for processing continuity
• Scheduled maintenance windows aligned to regional contractor availability
• Compliance with WA Department of Mines, Industry Regulation and Safety (DMIRS) operating conditions

Engineering and Extraction Infrastructure

Construction materials operations in this geological setting typically involve:

• Open-cut extraction of sand, gravel, or limestone deposits
• Primary crushing and screening circuits for aggregate grading
• Wash plant integration for specification-grade product output
• Physico-chemical quality control targeting particle size distribution and plasticity index compliance
• Stockpile management aligned to AS 2758 aggregate standards

ESG, Value Chain and Sustainability

South West WA operations face increasing pressure to align with ESG decarbonisation targets under state and federal frameworks. Key sustainability vectors applicable to Harris Myalup include:

• Transition pathway from diesel fleet toward electric or hybrid light vehicles
• On-site solar PV potential given high solar irradiance in the South West corridor
• Progressive rehabilitation obligations tied to extraction licence conditions
• Biodiversity offset management adjacent to protected coastal ecosystems
