Mt Holland Lithium

The Earl Grey Lithium Mine, core asset of the Mount Holland Lithium Project, is situated within the Yilgarn Mineral Field, Wheatbelt Region of Western Australia — approximately 500 km northeast of Perth. The remote semi-arid terrain imposes critical constraints on supply chain logistics, with all consumables, reagents, and capital equipment routed via Great Eastern Highway through Merredin and Southern Cross. Extended lead times and freight costs are primary procurement variables for any B2B vendor engaging this site.

The operation runs 24/7 continuous processing, generating relentless demand for diesel fuel, lubricants, and electrical infrastructure. Key operational procurement categories include:

• Diesel supply contracts for mobile fleet and auxiliary generation
• High-voltage substation maintenance and switchgear services
• Reagent supply (dense media separation chemicals)
• Tyre management and ground engagement tools (GET)
• SAP-integrated vendor onboarding via [email protected]

Earl Grey hosts one of the world's largest hard-rock lithium deposits, demanding high-intensity material handling systems. Engineering infrastructure includes:

• Large-scale conveyor systems linking pit to Dense Media Separation (DMS) plant
• Primary crushing and screening circuits with high-tonnage throughput
• Overland conveyors minimising truck haulage within the processing loop
• Dedicated spodumene concentrate loadout facilities
• Tin and tantalum by-product recovery circuits integrated into the flowsheet

Covalent Lithium operates under a robust ESG framework aligned with Wesfarmers' and SQM's decarbonisation commitments. Active sustainability initiatives include:

• Feasibility studies for on-site solar generation to reduce diesel dependency
• Electrification roadmap for light vehicle fleet (EVs)
• Water recycling and tailings management under WA DMP compliance
• Scope 1 & 2 emissions reduction targets embedded in capital planning
