U3O8 Corp. (TSX VENTURE:UWE), a Canadian-based company focused on uranium
exploration and resource expansion in South America, reports results from infill
drilling from the one kilometre ("km") long Aricheng West structure in the
Kurupung Batholith in Guyana (Figure 1). These drill results are being
incorporated into a National Instrument 43-101 ("NI 43-101") resource estimate
presently underway, with the aim of increasing the current uranium resource(1)
in the Kurupung Project.
"Infill drilling is confirming that the Aricheng West corridor is one of the
most consistently mineralized areas of the Kurupung Project, and we expect these
results to contribute to an updated resource estimate for completion at the end
of 2011," said Dr. Richard Spencer, U3O8 Corp's President and CEO. "As with many
of the structures in the Kurupung, uranium mineralization at Aricheng West
starts in the near-surface clay layer that offers an opportunity for low-cost
mining. Furthermore, the uranium mineral found in the soft clay is typically
easily extracted and tests are underway to confirm this from material from
Aricheng West."

Potential quantity and grade are based on drill results that define the
approximate length, thickness, depth and grade of the target area, but are
considered conceptual in nature. The exploration drilling reported in this
release constitutes infill drilling on the Aricheng West structure with the aim
of defining a mineral resource. No mineral resource has been completed on the
Aricheng West structure to date, and it is uncertain if further exploration will
result in such target being delineated as a mineral resource.
Aricheng West Structure
Uranium at Aricheng West is concentrated in a set of near-vertical, sheet-like
breccias that have an easterly trend that extends over 1km and is still open
along strike. The principal mineralized structures correspond closely with
corridors of unusually weak magnetism that goes beyond the area that has been
drilled (Figure 2). Extensions to these weakly magnetic corridors constitute
targets that warrant further exploration drilling. Most uranium found by U3O8
Corp. to date in the Kurupung lies within such demagnetized areas.
Mineralization at Aricheng West starts from the near-surface saprolite to at
least 340 metres ("m") below surface. Saprolite is the layer of clay that lies
between the soil and hard-rock, and is formed by the weathering of rock in
tropical environments. Original uranium minerals found in hard-rock at depth
have weathered to a secondary uranium-bearing mineral called torbernite in the
clay layer. This may represent a low-cost mining component to the Kurupung
Project since open-pit mining of the clay layer would be relatively inexpensive
while uranium is typically easily leached from torbernite. Metallurgical test
work is underway on samples of mineralized saprolite to determine the extent to
which uranium can be extracted. The saprolite varies in thickness from 10m to
80m over the Kurupung Project area, and averages 20m thick at Aricheng West.
Quality Assurance & Quality Control
QA/QC procedures for Aricheng West are the same as those used in U3O8 Corp's
exploration elsewhere in the Kurupung Project as described in the press release
dated April 20, 2011, available on the company's web site at www.u3o8corp.com
and on SEDAR at www.sedar.com.
Dr. Richard Spencer, President and CEO of U3O8 Corp., a Qualified Person within
the definition of that term in NI 43-101 of the Canadian Securities
Administrators, had overall responsibility for target and drill-site selection
at the Aricheng West target. Dr. Spencer has supervised the preparation of, and
verified, the technical information in this release.
About U3O8 Corp.
U3O8 Corp. is a Toronto-based exploration company, focused on exploration and
resource expansion of uranium and associated commodities in South America - a
promising new frontier for uranium exploration and development. U3O8 Corp. has
one of the most advanced portfolios of uranium projects in the region comprising
NI 43-101 compliant resources in Guyana and Argentina to significant historic
resources in Colombia.
(1) Scout drilling results suggest that the ten Kurupung structures identified
to date may contain a conceptual target of 13-18 million tonnes at a grade of
0.08% to 0.10% U3O8 (estimated 30 to 35mlb U3O8) including the initial NI 43-101
resource estimate. The initial NI 43-101 resource estimate of 5.8mlb Indicated
at an average grade of 0.10% (2.0 lbs/st) U3O8 and 1.3mlb Inferred at an average
grade of 0.09% (1.9 lbs/st) U3O8 has been reported on the Aricheng North and
Aricheng South structures in the Kurupung Batholith. Refer to the technical
report dated January 14, 2009 titled "A Technical Review of the Aricheng North
and Aricheng South Uranium Deposits in Western Guyana for U3O8 Corp. and
Prometheus Resources (Guyana) Inc.", available on U3O8 Corp's web site at
www.u3o8corp.com and on SEDAR at www.sedar.com.
