The Mount Gold Mine

The Mount is situated within the Coolgardie Goldfield, Goldfields-Esperance Region, Western Australia, approximately 550 km east of Perth. The terrain is characterised by extreme semi-arid conditions — annual rainfall below 280 mm, ambient temperatures exceeding 45°C in summer, and persistent evaporation rates that critically stress process water availability. Operational water supply, sourced from licensed borefield networks and recycled process circuits, is a primary engineering constraint governing mill throughput continuity and dust suppression across the pit floor and haul roads.

The Mount operates under Focus Minerals' broader Coolgardie Operations portfolio, feeding ore to the Three Mile Hill processing plant. As an active, operating asset, it demands continuous 24/7 diesel-powered haulage fleets and auxiliary equipment cycles. Diesel consumption across light vehicles, excavators, and haul trucks represents the dominant operational expenditure line. Power supply to processing infrastructure relies on grid-tied substations and diesel generation backup, sustaining uninterrupted CIL circuit operation critical for gold recovery yield and revenue continuity.

Ore handling at The Mount integrates a multi-stage material movement architecture: drill-and-blast open pit extraction, primary crushing, and conveyor belt systems transferring crushed material to the Three Mile Hill CIL plant. The conveyor network is engineered for high-tonnage throughput under abrasive, dust-laden conditions typical of Goldfields laterite and fresh rock ore types. Intensive material management — including ROM pad logistics, stockpile grade control, and reagent dosing (cyanide, lime, activated carbon) — defines the engineering complexity of sustaining target gold recovery rates above 90%.

Focus Minerals has publicly committed to ESG-aligned operational frameworks, with decarbonisation pathways under active evaluation across its Coolgardie assets. Initiatives include assessment of solar hybrid power integration to reduce diesel dependency, progressive rehabilitation of disturbed pit areas, and water recycling optimisation within the CIL circuit to minimise freshwater drawdown. Scope 1 and Scope 2 emissions reduction targets align with WA mining industry benchmarks. Transition to hybrid or electric light vehicles for site personnel movement represents a near-term ESG lever under consideration within the broader Focus Minerals sustainability roadmap.
