Ongoing Success in Drilling at Project Olza

VANCOUVER, March 14, 2013 /CNW/ - Rathdowney Resources Ltd. ("Rathdowney" or the "Company") (TSXV: RTH) is pleased to provide an update on progress at Project Olza, located 70 km north west of Krakow in Southern Poland, and to announce new results from the drill program.  Project Olza hosts Mississippi Valley Type (MVT) Zinc-Lead deposits in Poland's historic Upper Silesian Mining District, an area with extensive infrastructure including power and rail, and a skilled workforce.  The Upper Silesian MVT district is the largest of its kind in the world and continues to support long-life zinc-lead mines.

In September 2012, Rathdowney achieved a major milestone with the release of a substantial zinc-lead mineral resource at Project Olza.  The initial estimate of the inferred mineral resources in a portion of the extensive zinc-lead deposit in the Olza project-area are 21.2 Mt of 7.42% Zn+Pb at a 2.0% zinc cutoff.1  President and CEO John Barry stated, "The resource base provided by the September 2012 estimate establishes a critical mass and we are now moving forward with data collecting and studies to support a permitting process as outlined for mining projects in Poland. Community engagement activities that were initiated in 2010 have now broadened and we are deepening our discussions with local stakeholders. We have also formalized a process to consider all financing and partnership options available to us as we move forward to develop this exciting scalable deposit."

Rathdowney has completed additional drilling, with the holes in a pattern designed to optimise the testing and verification of historical estimates for the mineral deposit at Olza. The new holes, OLZ-201 to OLZ-223 inclusive, are located in the northern, central and southern parts of the east mineralized corridor (see drill hole map at http://www.hdgold.com/i/rdr/pdf/RTH_NR_DDH_Mar2013.pdf).

Mineralization at significant grades and widths continues to be encountered. A table of assay results for the new holes is appended to this release. Highlights include:

"Our Olza drilling has consistently returned very promising silver concentrations along with solid zinc-lead grades.  The potential for silver to enhance project economics is highlighted by the results from initial metallurgical testing that we announced earlier this week, showing excellent zinc and lead recoveries with a high silver grade reporting to the zinc concentrate," said Barry.  "This is another example of Rathdowney's ongoing work that is adding value to the project."

_______________________
1 Individual grades are 5.88% zinc and 1.54% lead.  For further details see Rathdowney News Release dated September 11, 2012 or the Company's technical report on the resource estimate that is filed at www.sedar.com.

Zinc demand continues to grow globally and key established mine operations are set to be taken offline over the medium term, resulting in looming deficits in concentrate supply from the world's mines. The Upper Silesian district has, by far, the most important accumulation of metal in any of the world's Mississippi Valley Type districts, with an estimated endowment of some 40 million tonnes of zinc and lead (USGS, 2010; endnote 1) and results from Project Olza show that it is an important part of this world class district.  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.
