Ni mineralization occurring in shears in Archean serpentinized peridotite near Nullagine. The bulk of the mineralization is attributed to the effects of hydrothermal and/or metasomatic activity along shears in the serpentine. The late veinlets of Ni minerals and the replacement of millerite and polydymite are attributed to supergene effects.
Located 23 km north of Nullagine.
