VANCOUVER,
Oct. 8, 2013 /CNW/ - Rathdowney
Resources Ltd. ("Rathdowney" or the "Company") (TSXV: RTH) is
pleased to report on additional studies of silver mineralization
and other activities at Project Olza, located 70 km northwest of
Krakow in southern Poland.
Olza is a Mississippi Valley Type (MVT) Zinc (dominant)-Lead-Silver
project situated in the historic Silesian mining district, the
world's largest MVT district which has seen long term production.
The district has extensive infrastructure including power, rail and
other facilities to support mine development.
The focus on added potential from silver was driven
by preliminary metallurgical work (see Rathdowney News Release
dated June 18, 2013) which showed
standard zinc and lead flotation conditions, without any upgrading,
produces optimum metallurgy and excellent recoveries to zinc and
lead concentrates with 83% recovery of silver to the zinc
concentrate.
During its drilling programs, Rathdowney's
technical team recognized that significant amounts of silver
accompany zinc and lead in these MVT deposits. From mid-2011
to early 2013, Rathdowney drilled two hundred and twenty-three
(223) holes in the central part of the Zawiercie and Rokitno
concessions, confirming the presence of substantial mineral
resources (21.2 million tonnes in the inferred category grading
7.42% combined zinc and lead at a 2.0% zinc cutoff1) in
this area as well as excellent potential for expansion.
Rathdowney's drilling also confirmed the presence of important
concentrations of silver in the deposit; some of the intersections
with key silver results are tabulated below. Full results
were previously disclosed in Company news releases in 2012 and 2013
(see news releases and drill hole location maps posted on the
Company website).

"Our drilling had shown that these MVT deposits
host zinc, lead and silver mineralization of significant grades and
thicknesses; however, the results are particularly compelling in
light of the more recently completed metallurgical studies," stated
President and CEO John Barry.
"Importantly, the presence of silver, and our ability to recover
it, indicates the opportunity for economic enhancement of the
currently identified mineral resources. This provides an
excellent basis to move forward. Our site team is focused on
project-data compilation and assessment and planning for ongoing
environmental and engineering and community engagement activities
to advance the project."

"Project Olza is located in a brownfield
setting, connected by rail to the fully-integrated mining
infrastructure at nearby Boleslaw that is currently supplied by
mines nearing the end of their operating life," added Barry. "These
are key advantages for our project that provide a major competitive
advantage over the small group of junior companies developing
zinc-lead-silver deposits around the world. We plan to work closely
with our neighbours to explore synergies that provide the very real
opportunity to reduce the capital costs and to shorten the
permitting timeline."

Sample preparation and analysis for Project Olza is done at ISO
17025:20 05 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. |
