Micaceous quartzite of the Hadrynian-Lower Cambrian Quartzite Range Formation (Hamill Group) was quarried between 1966 and 1971 from talus slopes in the vicinity of the confluence of Sheep and Waldie creeks, 12 kilometres southeast of Salmo.
Quartzite of various colours including buff, brown, green, red and grey was hand-sorted before being sold to local markets as facing stone. Well-developed micaceous partings enabled the stone to be split into slabs ranging from 1.3 to 10 centimetres thick.
A total of 453 tonnes of quartzite was quarried between 1966 and 1969.
