OREAS 920b was prepared from a blend of barren black slate and mine waste rock. The barren black slate was sourced from a quarry located in Victoria, Australia and the mine waste rock was sourced from the CSA mine located near the town of Cobar in central western New South Wales, Australia. The copper ore body of the CSA mine is hosted by the Early Devonian CSA Siltstone, a thinly bedded turbiditic sequence of carbonaceous siltstones and mudstones with minor coarser units. Iron-rich chlorite and silica are prominent alterations in the siltstone host. Twenty-three analytical laboratories participated in the following program:
