Scope of Work - Feasibility Study
Salt Lake is located at Lake Way in the Goldfields region of Western Australia, approximately 15 km south of Wiluna.
The Lake Way Plant Retrofit & Upgrade Project involves brownfields integration works within the existing SOP processing facility, requiring staged tie ins and careful coordination around live plant operations.
The scope of works includes the installation of a new two stage crushing circuit designed to maintain ore throughput capacity and improve feed size distribution to downstream process areas. This involves the decommissioning and removal of the existing feed preparation sizing equipment, followed by installation of new conveyors, transfer chutes, associated structural steelwork and services to accommodate the revised materials handling configuration.
Processing plant upgrades extend to the flotation area, where an additional four “reverse flotation” banks are being installed to enhance impurity removal capacity and improve brine quality. The upgrade package also incorporates four high frequency sizing screens to deliver improved screening performance at fine cut points, an oversize crusher to manage screen rejects, and a flotation brine clarifier to optimise solids-liquid separation prior to downstream processing.
Site execution is challenged by a combination of operational and environmental factors, including working at height during major equipment installation, extreme daytime temperatures typical of the Goldfields region, seasonal lightning activity, and consistently high wind conditions across the region. These conditions require stringent construction planning, engineering controls and adaptive work methods to maintain safe and continuous progress.
