Tournigan Energy Ltd. (TVC: TSX-V; TGP: Frankfurt) has received test
results from additional metallurgical testing for the Kuriskova uranium
project in eastern Slovakia. The test program was conducted on new
composites from more deposit areas which included new drill core samples
from the 2009-2010 drilling program. The work was performed at the Hazen
Research, Inc. (Hazen) laboratory facilities in Golden, Colorado.
Uranium and molybdenum will be recovered by conventional milling
methods. The additional test work is being undertaken to optimize the
process parameters (grind size, temperature, pressure oxidation time,
carbonate concentration, etc.) for recovery of uranium and molybdenum as
part of the ongoing test program for a prefeasibility study.
These tests confirm the initial test work completed at the Resource
Development, Inc. (RDI) laboratory facilities in Wheatridge, Colorado as
reported on November 3, 2009.
The test results indicate that over 90% of the uranium and 85% of the
molybdenum can be recovered by pressure oxidation using a whole ore
leach process in two hours utilizing an alkaline process (basic leaching
media) at a grind size of P80 300 mesh and temperature of 200oC.
These recoveries were obtained on two separate composites with an
average Bond work index of 13. The predominant uranium minerals are
uraninite and coffinite. The uranium recoveries of up to 93% in this
program are higher than those reported in the NI 43-101 technical report
dated May 10, 2010. Additional test work is planned during the ongoing
prefeasibility study to optimize other process parameters.
'These encouraging test results show that an alkaline leaching process
using benign carbonate reagents (not sulphuric acid) can effectively
recover both uranium and molybdenum from representative composite
samples,? said Dorian L. (Dusty) Nicol, Tournigan′s president and CEO.
'We are confident that the additional test work planned at Hazen will
confirm the development of our flow sheet using alkaline leaching that
has been used in the uranium industry since the 1960′s.?
Other aspects of the prefeasibility study continue to progress well. A
4,500 meter drill program has just begun at Kuriskova, focusing on the
high grade Zone 45 area.
