| Comments |
| Mineralisation at Peak Downs is associated with an ironstone unit localised along a shear zone and is concentrated within a strongly |
| chlorite altered zone thought to represent altered mafic volcanics. |
| The deposit is thought to have formed when syngenetic copper and zinc deposited by an exhalative, volcanogenic process was |
| remobilised during metamorphism and deformation. |
