    Lustrous black hausmannite crystals and needly cream brown calcite crystals are the dominant crystals on this piece of manganese carbonate matrix. Although not noticable with the naked eye, there are two broken crystals of translucent pinkish brown coloured seamannite, near the end of the green arrow. These are better viewed under magnification. This very rare manganese borophosphate mineral was found sparingly in the manganese carbonate area on the north wall of the opencut. It was only formally identified in 2000 and the mine closed in 1997. At the time it was only the third locality recorded worldwide. Because of only being identified after mine closure, very few specimans larger than micromounts were recovered, and the mineral is scarce on these larger pieces.
