Info:

Located approximately 500m south of the Minasville
school house (the occurrence can be accessed by an old woods road
behind the school)
Red sandstone is exposed in the trenches and is the major rock type
within the adjacent dumps. Coatings and veinlets of pyrolusite occur
along fractures within the sandstone. Manganese also occurs along
bedding planes, up to 3cm thick.
Between the late 1800's and early 1900's, two shafts were sunk and
several pits and trenches were sunk. |
