3. Location and setting Shea Creek deposits
Shea Creek
 Located in the western Athabasca Basin just south of the former Cluff
Lake mine site
 Most advanced of ten western Athabasca projects that are jointly owned
by UEX Corp. (49%) and AREVA Resources Canada

4. Shea Creek deposits
Cluff Location and infrastructure
Lake
deposits
 Project is 13 km south of
AREVA’s past producing Cluff
James Lake mine complex, which
Douglas River Creek produced 64 million pounds of
Project Project U3O8 between 1980 and 2002
Erica  Exploration operated by
Project AREVA and run out of the Cluff
Shea Lake Camp
Creek  Contiguous with the UEX-
Project
AREVA (49%-51% owned)
Douglas River and Erica
g
projects
 Road accessible with all
weather highway 955 running
Nikita through center of property;
Project airstrip at Cluff Lake

5. Shea Creek deposits
History
 Project first systematically explored during the early 1990’s by Amok
and COGEMA (predecessors to AREVA) with airborne and ground EM
surveys,
surveys identifying the NNW trending Saskatoon Lake Conductor
(SLC)
 In 1992, second drill hole to test the SLC intersected low grade
uranium mineralization SE of th A
i i li ti f the Anne d
deposit. F ll
it Follow up d illi t
drilling to
the northwest intersected the Anne deposit and subsequently Colette.
 Between 1994 and 2000, COGEMA drilled 156 holes mainly at Anne
and Colette. No drilling between 2001 and 2003 due to low U price.
 In 2004, UEX signed an option agreement to earn 49% from AREVA
by funding $30 million in exploration. Between 2004 and 2010, more
y g p
than 200 drill holes were completed which defined additional
mineralization, and led to the discovery and ongoing definition of the
Kianna and 58B deposits.
 UEX fully earned its 49% interest in the project in December, 2007

Resources based on drilling to Dec. 31, 2009
May, 2010 N.I. 43-101 complaint resources for the Kianna, Anne and
Colette deposits estimated by K. Palmer, P. Geo. of Golder Associates:
At a cut-off grade of 0.30% U3O8 :
Indicated = 1,872,600 tonnes at 1.54% U3O8 (63.57 million pounds U3O8
Inferred = 1,068,900 tonnes at 1.04% U3O8 (24.53 million p
, , ( pounds U3O8)
- At this cutoff, this is the largest pre-development resource in the Athabasca
Basin
At a higher cut-off grade of 1.50% U3O8 :
Indicated = 509,500 tonnes at 3.78% U3O8 (42.57 million pounds U3O8
Inferred = 188,700 tonnes at 2.83% U3O8 (11.77 million pounds U3O8)
The resources exclude results of the 2010 drilling that include expansion of
the Kianna deposit and identification of the 58B deposit. Mineralization is
still open in many areas – resources are growing and exploration potential is
exceptional

 Outside immediate area of
deposits, SLC is untested or only
very sparsely tested, with only 23
widely spaced holes along >20 km
of strike length
 Anomalous radioactivity and
prospective alteration in several
drill holes
 Parallel conductors to west and
east
 Near deposit upside: e.g.
Geotechnical holes 100 m west

respectively

27. Warning: forward looking statements! Shea Creek deposits
Conclusions: a growing district
 Cluff Lake and Shea Creek form a significant and growing western
Athabasca uranium district
 Most production historically at Cluff from basement style mineralization –
suggests further potential at Shea
 Mineralization open in many areas, both in basement and at
p y
unconformity, including new zones in the basement north of Kianna, and
open basement mineralization down dip in south Colette from 2007
intercepts such as 3.23% U3O8 over 8.0 metres in drill hole SHE-111-06.
 5+ km of Shea Creek trend along the SLC on Douglas River property
nearly completely untested, 400 m of strike length between Kianna and
58B tested by only one drill hole, and >10 km south southeast of Anne
y y
tested by only a few drill holes (including the Shea “discovery hole” SHE-
02 = 0.73% U3O8/0.7 m) : significant exploration upside
 Parallel conductors with alteration, resistivity lows (e.g. Klark Lake)
 $7.9 million budget for 2011 exploration at Shea and $9.7 million total for
West Athabasca – should be an exciting year
