Aurelia Metals has completed a pre-feasibility study (PFS) for the New Occidental Tailings Retreatment Project at its Peak operation in central-west New South Wales (NSW), Australia.
The project proposes reprocessing two gold-bearing, dry-stacked tailings stockpiles located around 3km from the Peak processing plant
The tailings were created from material that underwent processing in the late 1980s prior to being deposited in stockpiles. The study has resulted in Aurelia’s declaration of a maiden mineral resource estimate of 2.6 million tonnes (mt) at 0.65 grams per tonne (g/t) gold, and a maiden ore reserve estimate of 2.3mt at 0.64g/t gold, as of 30 April 2026. The tailings are set to be reclaimed and hauled for processing through the existing Peak plant’s tertiary ball mill and carbon-in-leach circuit.
Aurelia Metals forecasts production of approximately 32,000oz of saleable gold over ten years. The project’s capital cost is estimated at A$3.3m ($2.3m), with A$2.7m allocated to plant upgrades including a new wet trommel, dewatering cyclone and trash screen. Road improvements and preparatory works account for the remainder.
