VANCOUVER, June 18, 2013 /CNW/ - Rathdowney Resources Ltd. ("Rathdowney"
or the "Company") (TSXV: RTH) announces that preliminary metallurgical
testing of mineralization from its Project Olza has been completed and
has confirmed the initial excellent metallurgical results reported in
the Company's March 12, 2013 news release. Rathdowney's Olza
Zinc-Lead-Silver Project is located 70 km northwest of Krakow in
The following excellent results were confirmed on the bulk composite
Zinc - a projected zinc recovery of 92% to a 58% zinc concentrate. The
zinc concentrate was very low in iron, assaying 0.4% Fe, and its
magnesium content was 1.7% MgO.
Silver - a zinc concentrate assay of 179 g/t Ag, representing 83%
recovery of silver to the zinc concentrate.
Lead - a projected lead recovery of 90% or better to a lead concentrate
assaying 70% Pb. The actual lock-cycle result was 87% lead recovery to
a 79% lead concentrate.*
* Reducing the lead concentrate grade closer to a typical 70% Pb grade
would increase lead recovery to lead concentrate to 90% as quantified
from lead grade/recovery curves. The lead concentrate contained 55 g/t
Ag, representing 4% distribution of silver to the lead concentrate.
The preliminary test program was carried out at SGS Mineral Services UK
Ltd.'s test laboratory near Truro, Cornwall, UK under the direction of
Melis Engineering Ltd. of Saskatoon, Canada. A bulk composite sample
was prepared representing the Olza mineralization styles in proportion
to their relative abundance in the area of the initial mineral resource
estimate announced in September 2012 (21.2 Mt of inferred resources
grading 7.42% Zn+Pb at a 2.0% Zn cutoff1). Sulphides present in the sample include sphalerite, galena and
marcasite. The average head grade of the test composite was 6.2% Zn and
1.4% Pb for a combined head grade of 7.6% Zn+Pb with 19 g/t Ag. These
zinc and lead contents are comparable to the September 2012 mineral
Open cycle batch flotation tests previously completed and reported in
March 2013 on a bulk composite representing the Olza mineralization
determined that optimum metallurgy could be obtained using standard
zinc and lead flotation conditions. Based on these results, a standard
six-cycle lock-cycle test was completed to quantify recoveries and
concentrate grades under conditions approaching steady state.
"Completion of the preliminary metallurgical testwork for Rathdowney's
Project Olza is an important development," said President and CEO John
Barry. "The results have exceeded our expectations and show that
excellent recoveries to produce a high quality concentrate from the
Olza deposits are achievable."
1 Individual grades are 5.88% Zn and 1.54% Pb. Silver was not assayed in
historical holes so its grade was not included in the estimate. For
