Volcanic rocks on the north side of the complex and at Hurunui Peak show trachyte with extensive hydrothermal alteration, with laharic breccias and lava flows, intruded by sheets of leucocratic syenite. Formed from a violent volcanic explosion.
Strategic Elements explored in 2012, finding elevated silver and tellurium levels in a small outcrop next to a farm track, but provided no further details. At present this location represents a rock unit rather than a specimen site.
Abundant boehmite crystals to 0.2 mms in analcime, and associated calcite, found 150 metres from an old volcanic vent south-west of Hurunui Peak hosted by syenite. The syenite is interlocking subhedral crystals to 5 mms of perthitic alkali feldspar prismatic crystals of a complexly zoned amphibole, aegirine, and biotite.
