 ME Symbol:  "CDR"                                                       FOR IMMEDIATE RELEASE
 Cusip: 12878D 105                                                       September 29, 1997
 South Perth, Western Australia
 
 The directors are pleased to announce that the drilling program commenced at
 Abminga on August 19, 1997, and is progressing well ahead of schedule.  As
 at the end of September a total of 4,456 meters of reverse circulation
 drilling had been completed and field crews began their scheduled leave.
 
 Testing of four targets on Exploration Licence E1936 confirmed kimberlitic
 tuffs extending to the limit of drilling at 280 to 300 metres depth.  At
 varying depths all holes entered a water-saturated sandy tuff layer below
 which reverse circulation drilling was unable to deliver a sample.
 
 Approximately 40 tonnes of samples were selected for transport and observing
 in Perth.  Detailed mineralogical and petrological work is now progressing.
 Preliminary work has confirmed a fine to medium grained kimberlite rock and
 a carbonate-rich vein in several drill holes with characteristics consistent
 with diatreme facies lithologies.
 
 Consideration is now being given to a range of possible drilling methods
 that would allow penetration and good sample recovery below the
 water-saturated sandy tuff to the projected target depth of 500 metres.
 Contractors with suitable drilling equipment have been invited to submit
 proposals for this phase of the program.
 
 Caldera is engaged in diamond exploration in the Abminga region of northern
 South Australia.  Caldera is the major tenement holder in the region and is
 exploring a potentially world class kimberlite/lamproite field.
