Deflector Gold-Copper Mine

The Deflector Gold-Copper Mine is situated within the Yalgoo Mining Field, Mid-West region of Western Australia, embedded in the Gullewa Greenstone Belt of the Yilgarn Craton. The terrain is characterised by low-relief, semi-arid scrubland with lateritic surface profiles typical of the Western Australian shield. This flat-to-undulating topography simplifies bulk earthworks and surface infrastructure layout but demands robust dust suppression, haul road stabilisation, and water management strategies for any civil or earthmoving contractor operating on site.

Operated by Vault Minerals Limited, Deflector is an actively producing asset currently transitioning to an owner-operator model for its underground operations. The workforce is deployed on a FIFO rotation from Perth via Geraldton, placing sustained demand on:

• Camp catering, housekeeping, and facilities management
• Messing and wet-mess services for rotating crews
• Medical, communications, and emergency response infrastructure
• Consumables logistics along the Mid-West supply corridor

The deposit comprises six principal en échelon vein lodes — Western, Central, DaVinci, Contact, Southwest, and Spanish Galleon — requiring precision narrow-vein underground mining techniques. Key engineering procurement categories include:

• Low-profile LHD loaders and development jumbos suited to constrained stope geometries
• Raise-boring and ground support systems for vein-hosted stoping
• On-site processing circuit (gold-copper flotation and/or CIL) reagent supply
• Dual-fuel or diesel on-site power generation and reticulation

Primary copper mineralisation is chalcopyrite; oxide zones carry malachite, chrysocolla, and native copper.

Operating within the Yilgarn Craton corridor, Deflector's B2B supply chain is subject to Aboriginal Heritage compliance obligations under Western Australian heritage legislation, requiring due diligence from all ground-disturbing contractors. Vault Minerals' procurement framework presents strategic opportunities for:

• Registered Indigenous Business Australia and local Aboriginal-owned enterprise partnerships
• Heritage survey and cultural monitoring service providers
• Environmental monitoring, tailings management, and water stewardship contractors
• Workforce diversity and Reconciliation Action Plan-aligned service suppliers
