The  Board  of  Great Western Mining Corporation plc., the PLUS quoted Dublin based  uranium,  gold  &
silver exploration company, is pleased to announce results of the second bulk sample leaching test  on
ore from its high-impact project in the State of Nevada, U.S.A.

Background
GWMC is examining an ore deposit containing uranium and other precious metals in quartz monzonite  and
quartzite  located in a hydrothermal shear zone in Mineral County, Nevada. GWMC controls  100%  pf  an
approximately 7.4 square kilometre claim area.

The  independent  laboratory report contains head analyses and the results from  bottle-roll  leaching
tests.

Results
The  second  Bulk  Sample Test substituting a carbonate leach in place of acid  did  not  improve  the
recovery rates of U3O8 reported in the previous test. The use of a cyanidation leach for the gold  and
silver recovery supported the values achieved on the first test announced on 24 April 2008.

Chairman Emmett O'Connell said:

"Final  decision  on  the design of the leaching programme will be made on cost  of  recovery  and  an
environmental impact study, following completion of the Competent Persons Report and results from  the
drilling campaign."

               The Directors of the Company accept responsibility for this announcement.

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.
