Stewardson Lake Exploration Program

CALGARY, Feb. 11, 2013 /CNW/ - An exploration program and budget was recently 
approved by Cameco Corporation (Cameco) on Uravan Minerals Inc. ("Uravan ") 
Stewardson Lake project, Athabasca Basin(1), Northern Saskatchewan [map link]. 
The Stewardson Lake project is a joint exploration effort between Uravan and 
Cameco pursuant to the Halliday/Stewardson Option Agreement dated effective 
June 21, 2012[Press Release dated July 17, 2012]. 
The Stewardson Lake technical program consists of the following activity: 

    --  Property wide heliborne ZTEM geophysical survey totalling 777
        line-kilometres, conducted by Geotech Ltd
        [map link]
    --  Post ZTEM survey interpretation and data inversion processing
    --  Follow-up high-resolution ground geophysical program(s) in
        support of surface geochemical trends and anomalies to define
        drill targets.

Subsequent to the completion of the airborne ZTEM geophysical survey, follow 
up ground EM survey(s) and additional infill surface geochemistry may be 
required over prospective areas to focus on key geophysical targets that are 
supported by anomalous surface geochemistry.

The Stewardson Lake property overlies the Dufferin Lake Fault, which extends 
northeast-southwest across the central portion of the property. Historically, 
regional electromagnetic (EM) and magnetic surveys indicate a broad magnetic 
low on the western portion of the property, west of the Dufferin Lake Fault, 
transitioning to a magnetic high on the eastern side of the structure. Most of 
the historical geophysical surveys conducted by previous operators are 
considered test surveys to determine which techniques were effective to define 
conductors in the basement at depths >1100 meters. In 1996 an airborne UTEM 
survey mapped an interpreted/modeled low resistivity flat alteration halo in 
the lower part of the Athabasca Group sandstone covering a large area just 
west of the Dufferin Lake Fault and coincident with a broad boron anomaly 
mapped from boulder sampling. In 1997 diamond drill-hole VR-01 was completed 
at 1180 meters and positioned near the center of the boron-rich surface 
anomaly. The results of this drill-hole were positive, intersecting 
predominantly illite and chlorite clay alteration (>80%) below 700 meters, 
local uranium enrichment up to 3.78 ppm U308 in the sandstone, and anomalous 
(Pb) isotope values ((207)Pb/(206)Pb isotopic ratios) below 500 meters; 
however, no significant uranium mineralization was encountered at the 
unconformity (1135 meters).

In July 2011, Uravan completed a multifaceted surface geochemical sampling 
program over the Stewardson Lake project area(2). The surface sampling program 
consisted of collecting B- or C-horizon soil samples, vegetation samples 
consisting of twigs and needles from black spruce and jack pine trees, and 
tree cores from black spruce and jack pine(3). A total of 1663 survey 
locations were sampled on overlapping, 500 meter-spaced off-set sampling grids 
covering the property.

The south-west and south-central portion of the Stewardson Lake property is 
highlighted by the correlations of low radiogenic lead (Pb) isotope values 
((207)Pb/(206)Pb isotopic ratios) among clay and tree core samples [map link]. 
Multiple correlations between observed zones of geochemical enrichment and 
interpreted structural trends suggest preferential element migration through 
high permeability fluid conduits (fractures/faults) and may serve as important 
indicators to structurally controlled subsurface mineralization. It is 
anticipated by Uravan's technical group that the planned airborne ZTEM 
geophysical survey will highlight anomalous surface geochemical trends in 
support of drill targeting.

Dr. Colin Dunn, P. Geo., technical advisor for Uravan, is the Qualified Person 
for the purposes of NI 43-101 with respect to the technical information in 
this press release.

(1)The Athabasca Basin is an ancient (Paleoproterozoic) sandstone basin 
located in northern Saskatchewan, Canada. The Athabasca sandstone (Manitou 
Falls (MF) Formation) hosts high-grade uranium deposits at and below the 
unconformity between the sandstone and the older crystalline basement rocks. 
These unconformity-type uranium deposits occur in sandstones at the 
sandstone-basement unconformity contact (sandstone-hosted mineralization) and 
within the underlying structurally disrupted crystalline basement 
(basement-hosted mineralization). These unconformity-type uranium deposits 
account for about 28 percent of the world's primary uranium production. The 
ore grades are high, typically grading 2% to 20% U(3)0(8). 
(2)The Stewardson Lake surface anomalies were identified by a multifaceted 
geochemical sampling program completed by Uravan in the summer of 2011. This 
surface program capitalized on new geochemical technologies developed from a 
geochemical remote sensing study conducted over the Cigar West Uranium deposit 
(Cigar Lake Study)(4), which focused on the detection of buried 
unconformity-related uranium mineralization in under-explored areas in the 
Athabasca Basin 
(3)Clay-sized fractions (<2μm) were extracted from the B- and C-horizon soil 
samples prior to analysis and vegetation samples underwent ashing prior to 
analysis. The clay fractions and ashed vegetation tissues were analyzed by 
Acme Laboratories in Vancouver, British Columbia by ICP-MS following an aqua 
regia digestion for a suite of fifty-three (53) elements, plus all rare earth 
elements (REE) and lead (Pb) isotopes. Tree core samples were prepared by 
the Queen's Facility for Isotope Research(5) (QFIR) where they underwent total 
digestion and analysis using high resolution ICP-SFMS for fifty (50) elements 
and Pb isotopes. 
(4)The Cigar West Study was a collaborative applied research program conducted 
by Uravan and QFIR (Queen's Facility for Isotope Research(5))( )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. The Cigar Lake deposit is on the 
Waterbury/Cigar uranium property located in the Athabasca Basin, Saskatchewan, 
and is a joint venture partnership between Cameco Corporation, AREVA, Idemitsu 
Kosan Co. Ltd., and Tokyo Electric Power Co. [TEPCO]). 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.

Ontario is a state-of-the-art research facility, comprising a group of highly 
experienced research geochemists. The QFIR lab contains some of the most 
technologically advanced analytical equipment in Canada. Under the direction
