The Bradley Dyne sandstone quarry was opened up in a member of the Upper Cretaceous Nanaimo Group. The beds of sandstone strike 015 degrees and dip 40 degrees to the northwest, and are immediately accessible in a ridge of about 15 metres in height. The jointing is very irregular, with the most pronounced series at right angles to the dip, and facing the sea.

The unaltered stone is blue but the exposed weathered surface is a buff colour. The stone is fine grained but in many places it is filled with small round pellets of pyrite.

The only important building known to have been built from this stone is the Weiler Block at the corner of Government and Broughton streets in Victoria. No production figures are available.
