Distinctive range of paving, veneer and walling materials is won from 3 quarries located on a 150 metre thick band of interbedded metasiltstone and mica schist forming part of Tapanappa Formation of Kanmantoo Group of Cambrian age. Similar material is won from the Kanmantoo Quarry 7 km to the north, and probably within the same flagstone zone', but geological mapping is needed to confirm this. Current production totals approximately 4 - 5 000 tonnes per year. Reserves are large, totalling 14 225 000 tonnes. There is also considerable potential for other quarry sites in the Kanmantoo-Wistow district.
