                                         EXPANSION OF AREA UNDER CLAIM

Great  Western Mining Corporation plc, the Dublin based exploration company holding uranium, copper,  gold  and
silver  claims in Nevada, is pleased to announce that, following consideration of the recent Competent Person's
Report,  it has more than doubled the area under claim to 411 (four hundred and eleven) claims or approximately
34 sq. km. (thirty four square kilometres.)

All  of  the  subject area is within the prolific Walker Lane Belt Geological trend in Western Nevada.  Over  a
billion  tons  of copper ore with associated precious and industrial minerals have been produced  from  several
major mines located along this trend.

Further  geophysical  work  to  determine the best locations for an initial  ore  drilling  programme  will  be
initiated late this year, weather permitting.

The directors are pleased that the Competent Person's Report stated, inter-alia,

       *   Bottle roll leaching tests to samples crushed to pass 1/4 (6mm) screen opening produced excellent
           extractions of copper, precious metals and uranium.

       *   Geological and geophysical evidence suggests that the IWM claim group is very permissive for the
           discovery (of) a bulk-tonnage porphyry copper-molybdenum deposit of moderate depths. IWM claims 
           refer to the majority of the North-Eastern area under claim.

An appendix to the original report has been commenced to examine the viability of a low cost heap leaching
facility to process the easy-to-access high grade copper-oxide deposits.

THE DIRECTORS OF THE ISSUER ACCEPT RESPONSIBILITY FOR THE CONTENTS OF THIS ANNOUNCEMENT.
