Cu:Zn is somewhat variable.
Colour:
Bluish green
Lustre:
Vitreous, Pearly
Hardness:
2

Name:
Named after Minoh City, where it was discovered.
Type Locality:
Chemically and structurally related to schulenbergite.
Minohlite and schulenbergite may be intimately intergrown (Orlandi, 2013).
If minohlite is heated >50°C, it turns into schulenbergite (Orlandi, 2013).
