Cue Resources Ltd. Reports Core Analyses From Drilling at the Yuty Uranium Project, Paraguay

VANCOUVER, BRITISH COLUMBIA (TSX VENTURE: CUE) is pleased to
announce that it has received chemical and radiometric ("closed
can") analyses from 236 core samples taken at its Yuty uranium
project in Paraguay. The results fully confirm the validity of the
downhole radiometric grades reported previously. Drilling is
continuing with three drill rigs.
The half-meter core samples were crushed and ground at the SGS
laboratory in San Juan, Argentina. They were then shipped to Energy
Labs in Casper, Wyoming, for analysis by both closed can gamma and
by chemical analyses.
The results show excellent correlation between the chemical and
radiometric uranium grades. As is typically the case in sandstone
hosted deposits, at the lowest grade values, less than 0.02% U3O8,
the chemical grades are slightly lower than the radiometric grades.
This is referred to as negative disequilibrium. In the range of
0.02 to 0.10% U3O8, the radiometric grades and chemical grades are
very similar, showing that the uranium is in equilibrium for this
range. For higher values, greater than 0.10% U3O8, the chemical
grades are consistently higher than the radiometric grades. This
indicates a positive disequilibrium. Thus it can be stated that for
higher grades, the radiometric data somewhat underestimates the
true uranium content.
When the core analyses are compared to the downhole gamma logs,
on an interval basis since it is not possible to relate specific
samples to downhole readings, the core analyses give consistently
higher uranium concentrations.
Chris M. Healey, P.Geo, COO Cue, commented, "These results are
highly significant since they completely validate the use of
downhole radiometric logging to provide rapid and accurate
evaluations of each drill hole."
"Closed Can" uranium analysis works on the premise that, in a
particular deposit, the activities of 238U and 226Ra will be in
secular equilibrium being that the half-life of uranium is much
greater than that of 226Ra. Once the can is sealed with the sample
contained, conditions are ideal for attaining secular equilibrium
between 226Ra, 222Rn, and 214Bi, which is quantified using a 2" NaI
detector at the 214Bi 609 Kev energy region. Since 238U is the only
possible source of 226Ra, the specific activity of 238U is applied
to the tested activity of 226Ra to determine the total uranium
concentration. The efficiency of the counting system is determined
using certified 226Ra standards in the same geometry and density as
the canned core samples. The official method identification, which
will be used in data reporting, is EPA-901.1.
Chemical analysis is conducted on a strong mineral acid digest
of the dried and ground core. Following drying and grinding and
blending the core samples, a 1-gram subsample is taken and
delivered to a digestion vessel. Fifty % nitric acid is added to
the vessel (50 ml centrifuge tube), the vessel is loosely sealed
and heated in a water bath @ 95 degrees C for greater than 16
hours. Following the heating period, the volume is adjusted to a
known level, typically 50 ml. Uranium analysis (and other metals)
is performed on the solution by Inductively Coupled Argon Plasma
(ICP) emission spectroscopy against certified commercial standards
(EPA-6010).

Cue has the right to earn a 100% interest in the project; it
currently owns a 30% interest in Transandes Paraguay, S.A. and is
in the process of completing an earn-in for the remaining 70%.
Transandes has an exploration permit granting the exclusive rights
to explore for uranium on the Yuty project in south-east
Paraguay.
Cue has recently (September 6, 2007) announced a financing and
strategic alliance agreement with Cameco Global Exploration Ltd.
("Cameco"). That Letter Agreement established a strategic alliance
between the two companies, including three tranches of financing,
as well as a provision to create joint ventures within the Yuty
project area. Cameco is a wholly owned subsidiary of Cameco
Corporation, a reporting company having its shares posted and
called for trading on the Toronto and New York Stock Exchanges.
Cameco Corporation is the world's largest uranium producer.
The first two tranches were closed in 2007, for USD$4.5 Million
and CDN$2.5 Million respectively. The third tranche, CDN$12.5
Million, will close in early 2008, subject to Cue meeting certain
milestones.
