All mineable opal has been found in Bulldog Shale, mostly within a bleached profile at the contact of sandy claystone (Kopi) and underlying, grey-brown clay (Mud) near the base. Normally this interface (Level) is marked by a pebble or conglomerate layer which provided suitable crevices or permeability barriers for opal formation. Forty one holes totalling 650 metres were drilled with a rig provided by Olympic Dam Project management to Andamooka Progress and Opal Miners Association (APOMA) to find prospective areas, remote from existing opal fields. Although no opal or potch was encountered, 8 holes at 5 separate locations had good levels which warrant further investigation, particularly an area SE of White Dam Field.
