Three Mile Hill Processing plant
The Three Mile Hill (TMH) Processing Plant is the centrepiece of Focus Minerals’ operations in Coolgardie. Originally commissioned in 2009 and refurbished in 2023, the modern facility has a nameplate capacity of 1.2 million tonnes per annum and has consistently exceeded this rate since operations resumed. As part of the longer-term production strategy, Focus has upgraded its surface tailings storage capacity and converted the Greenfields pit into an in-pit tailings facility, providing tailings storage capacity for TMH for years to come.
TMH processes ore from multiple open pit and underground deposits across the Coolgardie Gold Project. By maximising throughput, maintaining flexibility to process a range of ore sources, and upholding high safety and environmental standards, TMH underpins the sustainable growth of Focus Minerals’ gold business in Western Australia.
Varischetti Village
Located on the outskirts of the Coolgardie township, the Varischetti Village was constructed in 2023 to support the FIFO operations at Coolgardie. The village is approximately 38 kilometres from the Kalgoorlie airport and 6 kilometres away from the Three Mile Hill plant, providing much convenience to the workforce and the operations.
This modern village is equipped with superb hospitality and brand-new facilities. Phase one of the village construction features 100 rooms, a commercial kitchen, recreation room, gym and other supporting facilities. The village was expanded in 2025 with the addition of 80 rooms to cater for the start of Bonnie Vale Underground Mining.
Coolgardie Mining Operations
The Bonnie Vale Underground Mine is the cornerstone of Focus’ growth strategy. The 2023 Bonnie Vale Ore Reserve published in September 2023, using a gold price of A$2,500 per oz and a cut-off grade of 1.87 g/t for stope design is 932,000 tonnes at 5.94g/t for 177,920oz of gold. Barminco has been engaged to provide mining services, with significant progress already achieved on decline development. Once in consistent production, Bonnie Vale will deliver higher-grade ore to the TMH plant, materially enhancing blended ore feed grade and gold output.
Our Coolgardie Gold Project is located approximately 600 kilometres East of Perth, Western Australia. As of the end of FY2024, the Project has 44.5 million tonnes of ore @ 1.87 g/t Au for approximately 2.68 Moz of gold. The mineral resources consist of open-pittable and underground deposits, all within short haulage distance to the TMH plant.
