A zinc and phosphorus-rich deposit hosted in diapiric breccias in late Proterozoic sedimentary rocks. It was mined for a few years in the 1970s by Chris Johnson, a mineral dealer, for mineral specimens (mostly Scholzite). Located on Martins Well station.

Metaswitzerite
Formula: Mn2+3(PO4)2 · 4H2O
Habit: micaceous blades
Colour: brown
Fluorescence: none
Reference: Deyhdration from switzerite cf. Zanazzi et al. (1986), Amer. Mineral. 71, 1224-8.
Parahopeite
Formula: Zn3(PO4)2 · 4H2O

Phosphoferrite ?
Formula: (Fe2+,Mn2+)3(PO4)2 · 3H2O
Description: Given that the description given in the Catalogue of South Australian Minerals - 1983 reads;
"minute clear crystals have been tentatively identified from the Reaphook Hill zinc phosphate deposit."

I would suggest this was gained from a visual identification of what was latter found to be Hillite (2003).
