Rathdowney Provides Additional Information To Investors: Zinc-Lead Resources Average 3 Metres In Thickness At Project Olza

 September 14, 2012, Vancouver, BC -- Rathdowney Resources Ltd. ("Rathdowney" or the "Company") (TSXV: RTH) recently announced an estimate of significant zinc-lead mineral resources for its Project Olza in Poland. The 100-square kilometre property is located in the Upper Silesian Mining District of southwestern Poland, an area of extensive Mississippi Valley-type deposits in which zinc-lead mining has taken place since the 12th century.

Mineralization at Project Olza occurs along a corridor which, in plan, follows a broadly curvilinear pattern with a total strike length of approximately 10 kilometres and width up to 1 kilometre. Stratabound mineralized zones, ranging in thickness from less than 1 metre to 20 metres, are mainly hosted in a flat-lying dolomitic unit 100 to 250 metres below surface.

Within this mineralized corridor Rathdowney has defined a mineral resource utilizing holes from historical and recent drilling. At a 2.0% zinc cutoff, these inferred mineral resources are 21.2 million tonnes grading 7.42% combined zinc and lead (5.88% zinc and 1.54% lead)1 . Mineralization within the areas that comprise the resource, shown on the map at http://rathdowneyresources.com/i/rdr/pdf/RTH_2012_Sept11_Drawing.pdf, averages approximately 3 metres in thickness.

The Qualified Person for the estimate is Robert L. Sandefur, P.E. of Chlumsky Armbrust & Meyer, who has reviewed the contents of this release. Further details are available in the Company's September 11, 2012 news release.
