The diamond and base metal potential is appraised based on recent company exploration for gold and diamond bearing kimberlites, with special reference to regional stratigraphy, tectonic structures based on the Echunga detailed low level aeromagnetic survey and the geophysical signature of the main stratigraphic units. The alluvial diamonds are present in the Adelaidean-Tertiary unconformity and are possibly of pre-Ordovician / Silurian age. Kimberlites may be present within either the Burra Group north or in the andalusite-staurolite metamorphic zones of the Adelaidean sediments or Kanmantoo Group to the north or east respectively. Small gold prospects concentrated east of the concealed Barossa Complex and west of the Williamstown - Meadows Fault Zone are interpreted to be possibly secondary remobilized deposits derived from paleoplacer deposits in the basal Adelaidean conglomerates.3 magnetic units with potential Zn-Pb Cu stratabound / stratiform mineralization, are interpreted.
