Attention Business Editors:

UEX Commences Summer/Fall 2007 Drilling Programs at the Raven and Horseshoe Deposits: Horseshoe Resource Definition Drilling on Schedule

     Trading Symbol: UEX-TSX
     VANCOUVER, July 11 /CNW/ - UEX Corporation ("UEX") is pleased to announce
that it has commenced the 2007 summer/fall exploration drilling programs at
the Raven and Horseshoe Deposits ("Raven", and "Horseshoe") located within
UEX's 100% owned Hidden Bay Project in the eastern Athabasca Basin of northern
Saskatchewan. Permits are in place, geologists and drill crews have mobilized
to the site, and Diamond drilling is under way. Britton Brothers of Smithers,
B.C. will continue to provide drilling services to the project. The
summer/fall 2007 program will comprise approximately 30,000 metres of drilling
to be completed by four drilling rigs.
     The majority of the program will be focused at Raven and Horseshoe, where
16,000 metres of drilling is planned to further define the extent of Horseshoe
mineralization to provide the basis for a National Instrument 43-101 ("N.I.
43-101") compliant resource estimate as well as test areas where Horseshoe
mineralization extends into previously unexplored areas, and a further
8,000�metres is planned at Raven to further trace mineralization continuity
for future resource definition and delineate potential new mineralized zones
identified by the recently reported winter 2007 drilling program (see UEX News
Release, June 14, 2007).
     The drilling program at Horseshoe is intended to provide sufficient
density of drill spacing to achieve an indicated resource status to allow
further progress towards a feasibility study. Golder Associates, who are also
performing baseline environmental studies at Raven and Horseshoe, will be
performing a resource calculation which is anticipated to be completed in
early 2008, once drilling results have been fully received and interpreted.
Golder personnel will also be involved in ongoing technical input into the
project to ensure all satisfactory steps, and sufficient information are
available to provide resource, engineering, metallurgical and environmental
components of the planned feasibility study.
     In addition to the 24,000 metres of drilling at Raven and Horseshoe,
6,000 metres of helicopter-supported drilling will test outlying targets on
the project. Much of this program will be devoted to testing exploration
targets in the Wolf Lake area in southern parts of the Hidden Bay Project.
Drilling here will follow-up on historically identified areas of alteration
and mineralization along two parallel, faulted graphitic conductors beneath a
shallow veneer of Athabasca sandstone. Historical drill results from drill
holes on widely spaced cross sections in this area include an intersection of
4.0 metres grading 0.204% U(3)O(8) in hole WO-84, and intersections of
0.127%�U(3)O(8) over 3.1 metres and 0.21% U(3)O(8) over 1.5 metres in hole
WO-25.
     Drilling is also planned in the West Rabbit area and Tent-Seal fault
system in the central and northern portions of the property. Central portions
of the potential source area of a large airborne radiometric and overburden
geochemical anomaly will be tested at West Rabbit adjacent to the economically
important Rabbit Lake fault. The potential for continuity of mineralization
identified on the adjacent McClean Lake property operated by AREVA Resources
Canada Ltd ("AREVA"), which may extend along the Tent-Seal fault on to the
Hidden Bay property, will also be tested.
     About the Raven and Horseshoe Deposits
     In 1980, Gulf estimated a total resource at Raven and Horseshoe of
6.7�million tonnes at an average grade of 0.16% U(3)O(8), representing
approximately 23 million contained pounds of U(3)O(8). This historical
resource estimate was based on widely-spaced drill holes and was not
calculated using current Canadian Institute of Mining, Metallurgy and
Petroleum categories and no current resource or reserve competence categories
were applied. As a result, such a resource estimate is not compliant with N.I.
43-101 and should not be relied upon.
