                 GREAT WESTERN MINING CORPORATION EXPANDS AREA UNDER CLAIM BY 24%

Great Western Mining Corp Plc, the Dublin and Nevada based mineral exploration company, is pleased
to  report  a further extension of its promising uranium and precious metal prospect in  Marietta,
Nevada.

Highlights -

    *       17 individual contiguous area claims have been added to the area claims already staked;
    *       This brings the total number of claims to 89 covering approximately 7.4 square kilometres;
    *       A Competent Persons Report is currently being compiled.

A  further 17 claims have been added to the Company's existing 72 claims bringing the total to  89
claims. This is equal to 7.4 square kilometres.

There  is  considerable competition for exploration acreage in the Company's  immediate  discovery
area  and  beyond.  One American group is even staking out the salt marsh some two  thousand  feet
below GWMC land claims.

A Competent Persons Report is currently being drafted following a comprehensive field examination.
Numerous  pit,  trench,  and rock-chip samples have been collected and are  undergoing  laboratory
testing. The results will be announced in due course.

A  second bulk sample report using a carbonate reagent to determine the most efficacious means  of
leach treatment is expected to be completed shortly.

             The Directors of the Issuer accept responsibility for this announcement.

                                             --ENDS--

Note to Editor:

Great  Western Mining Corporation plc is an Irish based exploration company, quoted  on  the  PLUS
Market.  The  company,  which concentrates on gold, silver and uranium exploration,  is  based  in
Nevada, USA. Its headquarters are in Dublin.

The  Great  Western Mining Corporation holds 89 gold, silver and uranium lode claims in  the  area
near  Marietta,  Mineral County, Nevada. This US state consistently ranks as one  of  the  leading
geologically prospective and pro-mining legal jurisdictions in the world today. Crucially,  it  is
also extremely stable from a geo-political perspective.

Furthermore,  as  nuclear power usage expands rapidly across the globe,  demand  for  the  world's
limited uranium resources will expand rapidly, pushing up the price for uranium ore.

The company plans to build a varied portfolio of uranium ore claims in politically secure areas.
