The Mount Coolon Lode consists of a single, 0.5 to 8m wide, south-east-trending vein.
Paragenesis of the lode: early epithermal colloform-banded quartz-adularia-sulphide-gold veining was overprinted by |
silica-biotite-actinolite-epidote-magnetite-pyrite during metamorphism. Late-stage sericite-pyrite alteration then formed. |
