Great  Western  Mining Corp. plc ("GWM"), the Dublin-based mineral exploration company,  announced
today  analytical  test  results  covering the latest batch of  mineral  samples  taken  from  its
polymetalic development prospect in Mineral County, Nevada, U.S.A.

GWM holds 100% interest in 34 square kilometers in the Huntoon Valley area.  Analytical tests were
carried out by Grand Junction Laboratories, Colorado, U.S.A.

Significant  results are given in the ten listed below. These show high values in heavy  minerals,
i.e.,  gold,  silver,  uranium,  copper,  lead and traces of  strategic  minerals  molybdenum  and
tungsten.

A   full   listing   of   all  one  hundred  samples  is  available  on  the  Company's   website,
http://greatwesternmining.com/index.php/test-results.   They   continue    to    show    extensive
mineralization around or adjacent to any mineral deposit at depth.

All  of  the  samples  below  were  taken from trenches, pits, grab  samples  and  adits  along  a
southwestern trend of the Walker Lane in which lie the newly acquired mineral claims, announced on
4 November 2009.

Emmett O'Connell, Chairman of GWM said, "Through the entire regime of testing and sampling over
the past three years, the potential and extension of the complex mineralization recorded has
broken to the upside. The next step in defining the structure and depth of the mineralization will
be to carry out a geo-physical survey as a prelude to a multi-core hole drilling campaign," he
concluded.

The latest results should be read in conjunction with tests, including bulk bottle roll leaching
tests, released in 2007, 2008 and 2009.
