Some specimens from this area may be labeled as coming from O'Brien which was a former mining town in this area centered on the former Miller Lake O'Brien Mine which in the 1960's was operated by Siscoe Mines Ltd. Only a few foundations and the concrete vault of the former mine office still remain.
