Processing access in the centre of WA’s gold district

Strategically located in Western Australia’s Murchison gold district, the Kirkalocka Processing Plant is undergoing refurbishment ahead of a Q2 2026 restart. The facility has a nameplate capacity of 2.0 million tonnes per annum, purpose-built for oxide, transitional and fresh ores, and is configured to deliver high metallurgical recovery and consistent campaign performance.

Processing

Ore is delivered to a run-of-mine stockpile with a capacity of 500,000 to 700,000 tonnes before single-stage crushing, SAG milling, gravity concentration, and carbon-in-leach treatment. A dedicated gravity circuit recovers free gold for processing in the gold room. The six-tank leach and adsorption circuit provides approximately 24 hours of retention, supporting high metallurgical recovery.

Toll milling

From Q2 2026, Kirkalocka will operate on a campaign basis for toll treatment. Each parcel will be processed as a discrete run to maintain complete separation through the circuit. Before scheduling, all ore will be subject to a compatibility assessment and metallurgical test work to determine plant configuration requirements and expected recovery performance.
