Exciting new results from Rathdowney's drilling at Project Olza

Including 7.8 m of 18.8% Zn+Pb in hole 165 and 8.4 m of 9.5% Zn+Pb in hole 135

VANCOUVER, Sept. 5, 2012 /CNW/ - Rathdowney Resources Ltd. ("Rathdowney" or the "Company") (TSXV: RTH) announces the results in forty-two additional holes from the Company's ongoing drilling program in Poland. The holes are located at drill centres in the central and southern parts of the extensive mineralized corridor that extends through Project Olza-area.

These new holes include some of the best grades and widths encountered in drilling to date and demonstrate the strength and persistence of the zinc-lead mineralization at Project Olza.  For example, Hole 165, which intersected 7.8 metres of 18.8% Zn+Pb, is 210 metres northwest of Hole 171 that encountered 8.7 metres of 7.9% Zn+Pb. Hole 135, which encountered 8.4 metres of 9.5% Zn+Pb, is 140 metres north of hole 162 which intersected 5.7 metres of 7.7% Zn+Pb including 1.3 metres of 20.0% Zn+Pb.  These and other highlights are tabulated below:

All diamond core holes, drilled vertically through the sub-horizontal mineralized horizon, so intersections represent approximate true widths.

In addition, these strong intersections occur in holes distributed throughout the areas drilled, as shown on the drill hole location map posted on the Company's website at http://www.hdgold.com/i/rdr/pdf/RTH_2012_Sept05_Drawing.pdf.  Locations for all 42 new holes are included on the map and their assay results are appended to this release.

Rathdowney President and CEO John Barry said: "The width and tenor of these mineralized intersections bode well for the soon-to-be-released, first compliant resource for this historical mining district - stay tuned."

Rathdowney's Project Olza is a Mississippi Valley Type (MVT) zinc-lead prospect situated in Poland's prolific Upper Silesian mining district which has been a centre of exploration and mining activity since 12^th century. According to a 2010 USGS report, the Upper Silesian has the most important metal accumulation in any of the world's MVT districts, with an estimated endowment of some 40 million tonnes of zinc and lead¹.  Because of the district's long mining history, key infrastructure such as power, and smelter facilities with rail access, is readily available.

Given its geological potential and excellent location, Rathdowney's Project Olza presents a compelling investment opportunity among a small peer-group of zinc-focused juniors.

Sample preparation and analysis for Project Olza is done at ISO 17025:2005 accredited Omac Laboratories Ltd. (Stewart Group/ALS Laboratory Group) in Loughrea, Ireland.  All samples are assayed for zinc, lead and silver by HNO₃, KCLO₄ and HBr and the final solution in dilute Aqua Regia is determined by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP‐OES) finish. These three elements and 42 additional elements are also determined for all samples by 4 acid digestion, followed by ICP‐OES finish. As part of a comprehensive QA/QC program, one standard and one replicate are inserted into the sample stream in each group of 20 samples, as well as one or more blanks in each analytical batch.
