Uranium Star Corp.: Extensive 2007 Exploration Program Identifies Polymetallic
Unconformity and Iron Oxide
Copper Gold Targets on Sagar Property
Uranium Star Corp. (OTCBB:
URST)(FRANKFURT: YE5) is pleased to provide an update on 2007
exploration activities for its Sagar Property in northern Quebec, and
outline exploration plans for 2008.
The extensive exploration program conducted in 2007 by Uranium Star
has identified polymetallic unconformity and Iron Oxide Copper Gold
(IOCG) targets on the Sagar Property. These targets were generated by
empirical evidence from the substantial database constructed from 2006
and 2007 exploration activities, and are believed to be volumetrically
more significant than the previous 'prize' at the Sagar Property, the
source for the Mistamisk (a.k.a. Clandestine) Boulder Field. The source
for the Mistamisk Boulder Field remains a target of consequence on the
Sagar property because of the potential for high grade uranium and gold
mineralization, but Uranium Star is realigning its exploration
activities to also pursue potentially larger polymetallic unconformity
and IOCG mineralized systems on the Sagar Property.
2007 Exploration
The objective of the 2007 exploration program was to identify the
source of the Mistamisk Boulder Field mineralization. The Mistamisk
Boulder Field is approximately 500 X 250 meters in size and contains
many radioactive gold-bearing albitized mudstone boulders. In a
Virginia Mines report, 70 boulders assayed an average of 64.9g/t gold
and 1.3% uranium (with values up to 640 g/t gold and 4.11% uranium).
During the course of 2007 exploration activities, 46 diamond drill
holes (DDH) (5,610 metres), and 164 reverse circulation (RC) holes
(2,625 metres) were drilled. The RC holes were pattern drilled to
establish a glacial transportation vector for the Mistamisk Boulder
Field mineralization. The DDH's were drilled to test geophysical
anomalies on the Sagar Property. In addition to drilling, other
exploration activities included prospecting of airborne geophysical
targets, grid emplacement, ground magnetometer surveying,
characterization of the litho-geochemical signature of Mistamisk
boulders, and soil sampling.
DDH SUS-07-16 returned the most significant assay values obtained
during the 2007 diamond drilling program, including 2.46% Cu over 6.71
metres and 0.254 g/t Au over 1.52 metres. Mineralization was associated
with chalcopyrite-filled hairline fractures within interbedded
silicified mudstone and sandstone. DDH SUS-07-18 intersected 2.04% Cu
over 0.76 metres in the same lithologic environment. Whole rock
analysis of the Mistamisk Boulder Field samples corroborated a
structural association with mineralization, with elemental associations
of uranium with lead, nickel, cobalt, copper, molybdenum and arsenic
indicating an unconformity associated polymetallic uranium style of
mineralization.
In addition to anomalous DDH results, new mineralized showings were
identified through the course of 2007 exploration activities on the
Sagar Property. These showings were narrow in nature which is
consistent with most of the mineralized showings identified to date on
the Sagar Property. These are predominantly narrow, structurally
controlled polymetallic veins. An examination of the Mistamisk Boulder
Field by geological staff in 2007 revealed a similar mineralization
footprint, in that no high grade mineralized boulder was found greater
than 1 meter in diameter, and that high grade mineralization was often
found in cobbles or within veins less than 30 cm wide within argillic
boulders. The source mineralization for the Mistamisk Boulder Field
constitutes a target of consequence because of its potential to host
high grade uranium and gold, but it is believed to be narrow, hence its
elusiveness. What the numerous narrow polymetallic veins found on the
Sagar Property indicate, however, is that there is considerable
potential for volumetrically significant unconformity and IOCG
mineralization on the property.
Geochemistry
Anomalous geochemistry (i.e. elevated gold, uranium, and copper)
identified during the 2007 exploration program in rock grab and diamond
drilling samples appeared to be structurally controlled, with
mineralization restricted to small veinlets and breccia zones. Whole
rock analysis of the Mistamisk Boulder Field samples corroborated a
structural association with mineralization, with elemental associations
of uranium with lead, nickel, cobalt, copper, molybdenum and arsenic
indicating an unconformity associated polymetallic uranium style of
mineralization. Whole rock analysis of high grade Mistamisk Boulder
Field samples also revealed that mineralization is intimately
associated with albitization, and kaolinite and illite clay alteration.
By utilizing the geochemical signature of the Mistamisk Boulder
Field, a multi-component normalized 'Boulder Field Index' was developed
and applied to the soil, reverse circulation drill hole and water
geochemical sample data sets for the Sagar Property. This data
manipulation has resulted in the identification of 17 prioritized soils
anomalies, and 6 RC anomalies that are associated with structures
interpreted through analysis of the compiled geophysical data for the
Sagar Property, and are priority targets for polymetallic
unconformity-style mineralization. Additionally, when this geochemical
data is taken in conjunction with interpreted clay alteration data
(i.e. kaolinite and illite) and hypothesized glacial dispersion trains,
three potential source areas for the Mistamisk Boulder Field
mineralization are identified.
Similar to the Boulder Field Index, a multi-component normalized
'IOCG Index' was developed and applied to RC, soil, and water
geochemical data collected over the Sagar Property. This IOCG Index
identified aerially extensive targets associated with a large east-west
trending structure that bisects the Romanet Horst in an area
under-explored by previous workers.
Future Exploration
Uranium Star will resume exploration on its Sagar Property in the
late winter/early spring of 2008 utilizing its fully provisioned, state
of the art exploration camp situated on the shore of Mistamisk Lake.
This will be facilitated by an all weather airstrip that was installed
during the 2007 exploration program.
Exploration activities will include targeted drilling for the source
mineralization of the Mistamisk Boulder Field, which is a target of
consequence, but will focus on potentially volumetrically significant
polymetallic unconformity and IOCG related mineralization.
The unconformity between Proterozoic and Archean aged rocks is known
to underlie the Property at relatively shallow depths. Target areas
consisting of graphitic bearing horizons (defined by geophysics) in
close proximity to major boundary faults of the horst are thought to be
prime targets for drilling. A number of coincident geophysical and
geochemical targets have been defined that require drill testing.
The styles of alteration and mineralization defined on the Property
to date also indicate that a hybrid type of IOCG deposit may be the
source of the Mistamisk boulders. A reinterpretation of the property
geology and geophysical surveys along with strong geochemical
signatures will allow the Company to zero in on specific drill targets
with IOCG affinities.

Drill core, reverse circulation chips and soil samples were sent to
ALS Chemex in Val d'Or for analysis. Reference standards, duplicates
and blanks were inserted into the sample streams as part of an ongoing
QA/QC program.
