The Chivas Gold Mine is an abandoned open pit, 8 kilometres east of Laverton and just south of the Barnicoat pit.
The lode is hosted in a series of north north-west to south south-east shear zones, bounding a segment of sandstone. Quartz breccia and ladder array quartz veins are common in the sandstone, with hematite alteration.
Nontronite and talc is common in the shear zones, derived from the alteration of high Mg basalt to the west. Reverse shearing is the dominant deformation event.
Chivas has produced 29 860 tonnes of ore at 0.91 g/t for only 819 ounces of gold.
