Uranium
Energy Corp Reports Independent NI 43-101 Resource Estimate at Goliad Project
Report
Estimates Measured & Indicated Resource of 5.4 Million Pounds and Inferred Resource of 1.5
Million Pounds U3O8
AUSTIN, TX - March 4,
2008 - Uranium Energy Corp (the "Company") is pleased to announce
that it has completed an updated technical report (the "Technical
Report") and independent resource estimate in accordance with the
provisions of National Instrument 43-101 ("NI 43-101") of the
Canadian Securities Administrators on its Goliad Project located in Goliad
County, Texas.
The complete Goliad
Project NI 43-101 Technical Report is expected to be filed and available
shortly on the SEDAR website, at www.sedar.com, and on the Company's website at www.uraniumenergy.com
. The
Technical Report is authored by Thomas A. Carothers, P.Geo., a qualified
person as defined in NI 43-101, who has over 30 years of uranium experience,
substantially in the South Texas Uranium trend. His experience includes
working directly for two operating ISR mining companies in South Texas, US
Steel and Tenneco Uranium, during the 1970s and 1980s.
The Technical Report
provides for a measured and indicated resource estimate for the Company's
Goliad Project of 5,475,200 pounds at an average grade of 0.05% eU3O8, up
from the previously reported and historical resource of 5.2 million pounds
eU3O8 which was set forth in the Company's previously filed Goliad Project NI
43-101 technical report. An additional 1,547,500 pounds of eU3O8 at an
average grade of 0.05% is classified as an inferred mineral resource in the
Technical Report. The estimate is based on the results from 1,086 drill
holes at the Goliad Project, 599 by Uranium Energy Corp, 487 historic.
Further details on the
quantity and grade for each mineral resource category identified in the
Technical Report are shown in the following tables:

Data used for the
resource estimate in the Technical Report includes electric logs from each of
Coastal Uranium (8), Moore Energy (479) and the Company (599). In
addition, PGT logging was conducted by Moore Energy on approximately 32
selected borings in order to establish the degree of disequilibrium within
the high-grade bodies. From May 2006 to December 2007, the Company
completed 599 confirmation borings, including those completed for core
retrieval and analysis. The core retrieval and analysis program was
designed to augment and confirm the positive PGT disequilibrium
("DEF") values recorded by Moore Energy for the four mineralized
sand horizons at Goliad which was reported on in the Company's previous NI
43-101 technical report.
In October 2007 the Company
undertook a coring program to obtain verification data for DEF development
from all four of the mineralized sands. Three core holes were completed
at wide-spaced locations within each of the mineralized zones; 15 to 18
approximate one-foot samples were taken through the mineralized portion of
each hole for chemical analyses for U308. Approximately 45 to 50
samples were collected from each of the defined mineralized zones (A-D).
Each of the
approximately one-foot samples were analyzed for cU308. The eU308 gamma log
value for that interval was determined to calculate the DEF values for each
nominal one-foot sample interval. All Company core and historic PGT
data from each sand zone were tabulated and weighted by data interval
thickness to determine a final DEF value. The intercepts with chemical
or PGT assay values below the 0.02% U308 cutoff were excluded from the
calculations. Resource estimates have also been calculated using only
those values greater than or equal to 0.02%. The DEF values obtained by
this method are consistent with previous DEF values obtained by the PGT data
logging program. The weighted values are as follows:
A Zone - 1.740
B Zone - 1.402
C Zone - 1.393
D Zone - 1.729
The values obtained for
the A, B, and C zones are essentially the same as determined by the PGT
method alone, however, the D-zone DEF value, with the core analyses and PGT
data, is 1.729. When treated as individual one-foot values, as had been
done with the A, B and C zones, and combined with the Company's assay-gamma
data, and weighted by data interval thickness, the 1.729 value was
reconfirmed. These values (rounded to the nearest tenth) are considered
by Mr. Carothers to be appropriate for use in the current resource
calculations for the Goliad Project. The DEF is taken into account with
the resource estimate of pounds of uranium, but not in the average grade
shown in the table above.
The method of resource
calculation used for this study is referred to as the polygonal method, or
the areas of equal influence ("AOI"). In this method polygons
are constructed around each sample point, or drill hole intercept in this
case, determined by perpendicular bisectors, drawn halfway between adjoining
sample points. This method is commonly used in computing resources in
tabular bodies. ESRI ArcGIS Thiessen Polygon Generator software was
used to construct the polygons around each high-grade intercept. The
AOI was established by the polygons, and the area within each polygon was
calculated by the computer.
The grade thickness of
the mineralized intercept for each respective polygon was assigned to that
polygon for estimating pounds of uranium in the various categories.
Tonnage factors based on laboratory bulk densities of core samples from
the Goliad Project were used. A factor of 16.9 cubic feet per ton was
used for the A, B, and C Zones, and a factor of 15.2 was used for the denser
D Zone. Resource estimates were made using a grade cutoff of 0.02%
eU3O8 at a grade thickness cutoff of 0.3 GT.
In the Technical Report
Mr. Carothers writes:
"In the author's
opinion, the verification coring program conducted in October 2007 at the
Goliad Project was done in a professional manner that resulted in additional
confirmation of the relationship between chemical assays (cU3O8) and
calibrated gamma log equivalent assays (eU3O8). The results also
confirmed the disequilibrium characteristics of the mineralized zones at the
site and consequently the positive correlation with the historic PFN log
assay and disequilibrium results. Confirmation drilling at the project
during the last three months of 2007 continued to show a high potential to
drill additional mineralization.
The drilling program
results, verification assays of core samples, leach amenability testing
results, and the success of other ISR operations mining from the Goliad
Formation sands in south Texas indicate that geologic and hydrogeologic
conditions at the Goliad Project are suitable for the use of ISR technology.
In the author's opinion, Uranium Energy Corp should continue with the
permitting process, including aquifer testing, additional drilling and the
necessary tasks to complete the feasibility studies that will lead to a
mining-production decision."
The technical
information in this news release has been prepared in accordance with the

Notice
to U.S. Investors
The mineral resources referred to herein have been estimated in
accordance with the definition standards on mineral resources of the Canadian
Institute of Mining, Metallurgy and Petroleum referred to in NI 43-101 and
are not compliant with U.S. Securities and Exchange Commission (the
"SEC") Industry Guide 7 guidelines. In addition, measured
mineral resources, indicated mineral resources and inferred mineral
resources, while recognized and required by Canadian regulations, are not
defined terms under SEC Industry Guide 7 and are normally not permitted to be
used in reports and registration statements filed with the SEC. Accordingly,
we have not reported them in the United States.
Investors are cautioned not to assume that any part or all of the
mineral resources in these categories will ever be converted into mineral
reserves. These terms have a great amount of uncertainty as to their
existence, and great uncertainty as to their economic and legal
feasibility. In
particular, it should be noted that mineral resources which are not mineral
reserves do not have demonstrated economic viability. It cannot be
assumed that all or any part of measured mineral resources, indicated mineral
resources or inferred mineral resources will ever be upgraded to a higher category.
In accordance with Canadian rules, estimates of inferred mineral resources
cannot form the basis of feasibility or other economic studies.
Investors are cautioned not to assume that any part of the reported measured
mineral resources, indicated mineral resources or inferred mineral resources
referred to in this news release and in the Technical Report are economically
or legally mineable.
