Description

A good sized matrix specimen containing a good coverage of blue grey spherical collinsite crystals and cream coloured platy hillite crystals from the type deposit. Hillite has previously been referred to as 'zincian collinsite' before it was recognized as a new species. Some minor scholzite is also present.

Reaphook Hill was exploited for it's suite of rare zinc phosphates in the 1970s & 80s and became renowned for the magnificent specimens of scholzite that were unearthed. Since then access to the area has been limited by the current landowners.
