A rich specimen for Parwanite, a very rare cave mineral found at this locality only. The parwanite forms tiny globules less than 1mm in size on the brown portions of this specimen. The brown is probably Montmorillinite which is in the larger, white chalky mass of Taranakite. The specimen is originally from the Jack Parnau collection and there is a letter to Parnau explaining the specimen itself. See prov. tab.
