- Sphalerite is generally lighter in colour than Dundas sphalerite and appears a gemmy yellow colour.
- The barite is very white and platy when crystallized.
- Very sharp octahedral galena crystals have been found.
- Vugs with nice associations of galena, barite, marcasite and dolomite occur.
- Most crystals are small and suitable for micro-mounts.
