Rathdowney Resources Ltd. (TSX-V: RTH): Significant Zinc-Lead Resources at Rathdowney's Olza Project With clear potential to add substantial resources and make new discoveries

September 11, 2012, Vancouver, BC – Rathdowney Resources Ltd. (“Rathdowney” or the “Company”) (TSXV: RTH) announces an estimate of significant zinc-lead mineral resources for its Project Olza in Poland. These results, based on 780 core holes drilled historically by the Polish State as well as confirmatory drilling in 175 core holes carried out by Rathdowney since June 2011, represent the first estimate carried out under modern standards, in compliance with Canadian regulations under National Instrument 43-101. The 100-square kilometre Project Olza 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.

Rathdowney has undertaken a comprehensive program over the past 1½ years to assess the Olza zinc-lead deposits. This work has involved retrieval, compilation and detailed review of the historical database, including an assessment of key information such as sampling and assay procedures and drill-hole recoveries, planning and executing a 175-hole drilling program in the central part of the area that comprises Project Olza.

A total of 955 diamond drill holes from historical and recent drilling were used to establish the current resource model. Mineralization occurs along a mineralized corridor which, in plan, follows a broadly curvilinear pattern with a total strike length of approximately 10 kilometres and width up to 1 kilometre. Within this mineralized corridor, stratabound mineralized zones; ranging in thickness from less than 1 metre to 20 metres, and averaging 1.5 metres are mainly hosted within a flat-lying dolomitic unit lying 100 to 250 metres below surface…
