PR Newswire (Canada)
CALGARY, Oct. 31, 2011 /CNW/ - Uravan Minerals Inc. (Uravan)
recently completed a two (2) hole (OR11-06 and OR11-07) diamond
drilling program totaling 1597 meters drilled on its Outer Ring
(OR) and contiguous Mathison Lake (MATH) uranium projects in the
Pasfield Lake area of the Athabasca Basin(1) [view map]. This is a
follow-up program based on encouraging information obtained from
Uravan's previous OR drill program completed in July,2011 (OR11-01
to OR11-5) [August 22, 2011 press release]. The program originally
anticipated the completion of three (3) drill-holes; however, due
to increased drill depths, budgetary considerations and other
logistical limitations, the program was concluded after completing
two drill holes. The OR-MATH drill program targeted selected
surface geochemical signatures that correlate with a strong NE-SW
trending EM conductor (the "Pasfield Conductor") [September 27,
2011 press release]. The Pasfield Conductor coincides with a linear
low magnetic susceptibility feature that together form a corridor
that transects the MATH project and extends onto the OR project to
the southwest. The selected surface geochemical anomalies were
identified from a multifaceted surface sampling program completed
over the OR project in 2010 and over the MATH project in June 2011.
This surface geochemical program capitalized on new innovative
geochemical technologies developed by Uravan's technical group and
collaborative research partners from a pilot study conducted on the
Cigar West uranium deposit (Cigar West Study)( 2). The preliminary
results of potential uranium-bearing intersections from this
drilling were obtained from down-hole Natural Gamma surveys.
Radioactivity levels measured in drill-holes OR11-06 and OR11-07
were comparable to the radioactivity levels measured in OR11-01 to
OR11-05 completed on the OR project in July 2011 [August 22, 2011
press release]. In addition, OR11-07 intersected a major fault zone
approximately 54 meters below the unconformity(3). This structure
is interpreted to be a major reactivated reverse basement fault
that potentially represents a NW dipping NE-SW trending structure
interpreted from a ZTEM geophysical survey completed by ESO Uranium
in 2009. The significance of this structure is not clear at
this point, however, the intersection of a major structure in the
Athabasca Basin that correlates with anomalous surface
geochemistry, and coincident EM conductor/magnetic low corridor is
considered positive. More work is required. The seven (7)
drill-hole (OR11-1 to OR11-7) reconnaissance program on the OR and
MATH projects have identified a number of key features required for
uranium mineralization in the Athabasca Basin: -- The presence of
high radioactivity levels above and below the unconformity; --
Persistent sandstone bleaching/alteration above the unconformity
coincident with broad zones of secondary hematite alteration; --
The presence of illiteclay alteration occurring in some of the
drill-holes over varying thicknesses at and above the unconformity;
-- The presence of major fracturing in the Athabasca Sandstone
section; and -- The intersection of a major reverse fault in the
underlying basement units, suggestive of structural reactivation.
The combined assessment of all data collected at this preliminary
stage has allowed Uravan's technical team to significantly advance
and refine favourable target areas for future diamond drill
programs on the OR and MATH projects. Mr. Larry Lahusen, CEO of
Uravan states: "At this preliminary stage, data analysis from the
core recovered at the unconformity from drill-holes recently
completed on the OR and MATH projects corroborates the geochemical
results obtained from surface samples systematically collected from
near surface environments (clay minerals form B-and C-horizon
soils, vegetation samples and tree-cores) on these projects.
Although this is early times in the development of this new
geochemical exploration technique, it appears the geochemical
indicators from near surface environments are mapping element
associations and isotopic compositions that originate from the
unconformity at depth. Going forward, the interpretation and
refinement of these new geochemical exploration techniques clearly
has the potential to vector drilling to the most probable location
of uranium deposits at depth." Drill holes OR11-06 and OR11-07 were
probed using a down-hole triple-gamma geophysical survey tool for
measuring radioactivity in the borehole trace. All zones of high
radioactivity intersected were systematically sampled and will be
assayed for their uranium concentrations. All drill cores were
systematically scanned using ASD Terraspec instrumentation for
determining clay mineralogy; a means of establishing the presence
or lack of hydrothermal alteration. The drill core has been
routinely sampled and will be assayed by multi-element ICP-MS for
52 elements plus all the REE and Pb isotopes at Acme Labs in
Vancouver. The Queen's Facility for Isotope Research(4) (QFIR) will
conduct further analytical techniques on core samples to determine
the concentration of certain isotopic compositions using
High-Resolution ICP-MS. The analytical data resulting from the core
recovered from the OR drilling program will be the focus of a
new collaborative research study between Uravan and QFIR, and the
Natural Sciences and Engineering Research Council of Canada
(NSERC)( 4) [PR dated April 26, 2011]. The OR drill program was
managed and directed by Uravan's technical group. Drilling
operations were performed by Bryson Drilling Ltd. from Archerwill,
Saskatchewan. Dr. Colin Dunn, P. Geo., technical advisor for
Uravan(5), is the Qualified Person for the purposes of NI 43-101

------------------------------ (1)The Athabasca Basin is an ancient
(Paleoproterozoic) sandstone basin located in northern
Saskatchewan, Canada. The Athabasca Basin hosts high-grade
unconformity-type uranium deposits that account for about 28
percent of the world's primary uranium production. These
unconformity-type uranium deposits occur in sandstones (Athabasca
Sandstone) at the basement-sandstone unconformity contact
(sandstone-hosted mineralization) and within the underlying
structurally disrupted crystalline basement (basement-hosted
mineralization). The ore grades are high, typically grading 5% to
20% U(3)0(8).The interior of the Athabasca Basin, which includes
the OR property, is under-explored relative to the high-grade
unconformity-related uranium deposits currently being exploited
near the eastern margin of the basin. The OR drill program is one
of the first significant exploration effort conducted in this more
basin-ward region and even more significant considering the
drilling is targeting surface geochemical anomalies versus
conventional blind geophysical (EM) conductors. (2)The Cigar Lake
deposit is on the Waterbury/Cigar uranium property; a joint venture
partnership between Cameco Corporation, AREVA, Idemitsu Kosan Co.
Ltd., and Tokyo Electric Power Co. [TEPCO]) located in the
Athabasca Basin, Saskatchewan. Uravan thanks both AREVA and Cameco
for their collaboration and gracious support for the Cigar West
Study; and the support provided by the Cigar Lake facility during
our field operations. The Cigar West Study was a collaborative
applied research program conducted by Uravan and QFIR (Queen's
Facility for Isotope Research) in 2009 over a known high-grade
uranium deposit in the Athabasca Basin. The study was designed to
develop new surface geochemical techniques that can better identify
bedrock sources of uranium mineralization at depth. This
research clearly identified distinctive elements and isotopic
compositions that have been mobilized from the deposit (geosphere)
to the surface media (plants and soils) from depths 450 meters.
(3)Unconformity in this writing is defined as the contact between
the Athabasca Sandstone and the underlying crystalline basement
rocks. (4)The NSERC supports university students in their advanced

Uravan's technical group to develop new exploration technologies
using applied research. (5)Dr. Colin Dunn, an independent
specialist in biogeochemistry, is working closely with Uravan's
technical group and QFIR to advance the interpretation of
biogeochemical results. Dr. Kurt Kyser and Dr. Colin Dunn are key
technical advisors for Uravan. Uravan is a Calgary Alberta based
