Daisy Milano

The Daisy Mine forms part of Vault Minerals Limited's Mount Monger Operation, situated within the East Coolgardie Goldfield, approximately 40 km southeast of Kalgoorlie-Boulder, Western Australia. The terrain is characterised by flat to gently undulating semi-arid scrubland, typical of the Yilgarn Craton. Ambient temperatures routinely exceed 45°C in summer months, imposing severe thermal stress on surface infrastructure, mobile fleet cooling systems, and underground ventilation circuits — a primary engineering constraint for all B2B equipment suppliers operating on site.

Operating under Vault Minerals (formed via the June 2024 merger of Red 5 Limited and Silver Lake Resources), the Daisy Complex sustains continuous underground production cycles demanding uninterrupted mechanical availability. The nearest heavy-equipment service corridor is Kalgoorlie-Boulder, making local workshop capacity — including mobile brake, hydraulic, and drivetrain repair units — a critical procurement priority. Unplanned downtime in this single-asset operation carries disproportionate cost exposure, elevating demand for on-call OEM-certified field service contractors and rapid parts logistics agreements.

The Daisy Complex feeds a centralised processing facility incorporating a primary grinding circuit (SAG/ball mill configuration) and downstream gravity-CIL recovery. Ore hardness variability across the East Coolgardie shear zones demands precise mill liner management and real-time particle size monitoring. Flotation pre-concentration stages impose stringent physico-chemical requirements including:

• pH control within tight reagent dosing tolerances
• High-wear slurry pump and cyclone replacement schedules
• Reagent supply chains for cyanide, lime, and flocculants
• Continuous ventilation upgrades to manage underground heat and diesel particulate

Vault Minerals has inherited consolidated ESG commitments from both legacy entities (Red 5 and Silver Lake), targeting measurable Scope 1 and Scope 2 emissions reductions across the Mount Monger portfolio. Key decarbonisation vectors relevant to B2B suppliers include:

• Evaluation of hybrid and battery-electric light vehicles for surface operations
• Solar-diesel hybrid power integration to reduce grid and genset dependency
• Water recycling infrastructure to address semi-arid site constraints
• Supplier ESG alignment requirements increasingly embedded in procurement frameworks
