U3O8 Corp. Confirms Significant NI 43-101 Compliant Uranium, Phosphate & Vanadium Resources on the Berlin Project, Colombia

U3O8 Corp. (TSX VENTURE:UWE), a Canadian-based company focused on exploration
and resource expansion of uranium and associated commodities in South America,
reports a maiden National Instrument 43-101 ("NI 43-101") resource estimate on
its Berlin Project in Colombia. The resource was prepared by Coffey Mining Pty
Ltd based on 82 bore holes for 18,685 metres ("m") drilled on the southern three
kilometres ("km") of the 10.5km mineralized trend at Berlin.


At a cut-off grade of 0.04% U3O8, the uranium resource is:



--  Indicated Resource: 1.5 million pounds ("mlb") U3O8 (0.6 million tonnes
    at a grade of 0.11% U3O8); and 
--  Inferred Resource: 19.9mlb U3O8 (8.1 million tonnes at a grade of 0.11%
    U3O8). 



Contained in the same mineralized layer as the uranium resource, are resources of:



--  Phosphate - Inferred Resource: 0.8 million tonnes (8.7 million tonnes at
    a grade of 9.3% P2O5); and 
--  Vanadium - Inferred Resource: 97mlb V2O5 (8.7 million tonnes at a grade
    of 0.50% V2O5). 



"U3O8 Corp. is pleased to report an initial NI 43-101 resource of such
significant size for a suite of commodities that our recently announced
metallurgical tests prove can be efficiently extracted from the mineralized
rock," said Dr. Richard Spencer, President and CEO of U3O8 Corp. "Our resource
drilling has shown that the mineralized unit at Berlin is remarkably continuous
over the southernmost 3km of the project. Our path forward is simple: we intend
to continue drilling with two rigs - one aimed at exploration drilling to test
the additional 7.5km of strike to the north of the resource area that has never
been drilled, but where our trenching has encountered similar mineralization.
The second rig will focus on expanding the Berlin resource. In addition, we plan
to commence a scoping study in 2012."

Mineralization and Nature of Resource

The mineralized layer in the Berlin Project occurs in a canoe-shaped fold that,
in cross-section, has an asymmetric "U"-shape. The mineralized interval lies
near the interface between carbonate or sandstone host-rocks and an overlying,
black shale unit. Uranium mineralization constitutes a clearly defined,
continuous, tabular unit. The tight constraint of uranium to this unit results
in minimal change in the size of the resource at various uranium cut-off grades.
For example, doubling the cut-off grade from 0.04% to 0.08% U3O8 results in a
decrease in the resource of only 3% (Table 1).


Resource Growth Potential of Other Commodities

Mineralization in other commodities such as vanadium, phosphate and yttrium
occur in the uranium-bearing layer as well as in the overlying rock - so these
other commodities generally occur in a thicker layer that contains the more
confined uranium-bearing layer. The average thickness of the uranium-bearing
layer is 3m. This feature of the mineralization means that there is a strong
possibility of increasing the resource of the other commodities at Berlin once
mining and processing cost parameters have been more definitively established.
These costs will initially be estimated in a scoping study, and thereafter, the
cut-off value used for resource estimation is likely to be based on a dollar
rock-value instead of a specific uranium grade as was used in the current
resource estimate.


Details of the Resource Estimate



--  The drill hole database in the vicinity of the estimation consists of 82
    diamond drill holes totalling 18,551m and 30 surface trenches totalling
    100m. Drill hole spacing ranges from 60m x 100m to 100m x 200m.
    
    
--  Both the diamond drill holes and the trenches were used to model the
    mineralization geometry, however only the assay data from the diamond
    drill holes were used in the grade estimate.
    
    
--  The drill holes were typically drilled along east- to northeast-trending
    lines, with dip ranging from 60 degrees to 90 degrees. The drilling
    angle and orientation was designed to intersect the mineralization so as
    to produce a true-thickness intercept. However, a small number of drill
    holes intersected the mineralization at acute angles where the shape of
    the folded mineralized layer is different in detail from the simple fold
    shape targeted.
    
    
--  The drill core was halved using a diamond saw, then character-sampled
    based upon estimated grade from measured radioactivity and lithology to
    a minimum nominal length of 20 centimetres ("cm"), and a maximum length
    of 1.6m. The average sample length was 80cm.
    
    
--  Gamma ray measurements, recorded with a down-hole Mount Sopris probe,
    calibrated in Grand Junction, Colorado, were used to estimate the
    uranium grade ("eU3O8") where chemical assays were not available due to
    poor core recovery. eU3O8 values were used for approximately 31% of the
    assay intervals. Gamma ray data were measured for most of the bore holes
    drilled, providing a comparison between chemical assays and eU3O8 data.
    Assay and estimated U3O8 values showed a very good correlation.
    
    
--  Density for the resource was based upon 27 measurements taken from
    within the mineralization using the water immersion method.
    
    
--  The mineralization outline was based upon a nominal 0.04% U3O8 halo,
    with consideration given to the mineralized limestone lithology. Based
    upon the lithology modelling, a nominal weathering surface was defined
    as being 10m below the topographic surface.
    
    
--  The topographic surface was based upon a digital elevation model ("DEM")
    supplied surface obtained from ground-controlled precision satellite
    photographs using high-definition satellite elevation.
    
    
--  A total of 317 mineralized intervals were used in the resource model.
    69% of these were chemically assayed utilizing values using Inductively
    Coupled Plasma Mass Spectrometry ("ICP-MS"), supported by X-ray
    Fluorescence ("XRF") analysis for samples with elevated phosphate.
    Samples were prepared by ALS Chemex in its facility in Bogota, Colombia,
    and the samples were shipped to ALS Chemex's assay laboratory in
    Vancouver, Canada, for analysis. Radiometric data were used for 99
    intervals. The assay data was composited to 0.8m intervals for the
    resource estimation. Variography and search neighbourhood analysis were
    also conducted as an input into the U3O8 grade estimation.
    
    
--  Ordinary Kriging was utilized for the U3O8 grade estimate and inverse
    distance to the power of two was used to estimate the multi-element
    data. Top-cutting of the assay data was not considered necessary for the
    estimates.
    
    
--  The estimate was classified as Indicated and Inferred based upon the
    demonstrated geological and grade continuity, and the drill hole
    spacing.
    
    
--  The following comments and recommendations are made:  
    --  Further density data is required to characterize the density of the
        deposit, particularly in the weathered portion of the deposit.  
    --  Further work is required to refine the base of weathering.  
    --  Although the overall geometry and trend of the mineralization is
        well defined, infill drilling is required to adequately define the
        areas of complex folding and structure. Further investigations are
        also required to determine if faulting is affecting the
        mineralization, particularly for portions considered to be suitable
        for underground mining.
