U3O8
Corp?s drilling confirms consistent uranium,
vanadium, phosphate & rare earth mineralization extending over 2.5km in the
Berlin Project, Colombia
Trenching shows mineralization continues northward
beyond the historic resource area
TORONTO, Ontario ? May 25, 2011 ? U3O8 Corp. (TSX Venture: UWE) a
Canadian-based company focused on exploration and resource expansion of uranium
and associated commodities in South America, reports assay results from a
further four bore holes and three trenches completed in the Berlin Project in
Caldas Province, Colombia. The Berlin Project is a sediment-hosted,
multi-commodity prospect with a historic resource1 of 12.9 million tonnes at an average grade of 0.13% U3O8
(38 million pounds (?mlb?) U3O8)
estimated on the southernmost 4.4 kilometres (?km?) of a 10.5km long mineralized trend. This
historic work did not include estimates for commodities other than uranium.
?U3O8 Corp?s exploration drilling has now confirmed consistent,
multi-commodity mineralization in the southernmost 2.5km of the Berlin trend,? said Dr. Richard Spencer. ?Trenching
has also shown that the mineralization occurs in the northern part of the
trend, corroborating previous exploration for the first time, and highlighting
the upside of the project beyond the historic resource. Trenching will continue
along the whole 10.5km trend, followed by drilling. In the southern
portion, we are now focused on infill drilling with the aim of converting part
of the historic resource into an initial National Instrument 43-101 (?NI 43-101?) uranium resource in late 2011.?
Dr. Spencer continued, ?Metallurgical testing on drill core samples from
Berlin is ongoing to define a means of extracting the various metals and
phosphate, although the work is progressing more slowly than anticipated and
results are now expected in the latter half of the year. A bulk sample
has also recently been sent to Australian Nuclear Science and Technology
Organization (ANSTO) for further work. ANSTO has extensive experience
with similar types of ore ? it
established the process to extract uranium and rare earths from phosphate,
generating co-product phosphoric acid, at the Nolans
Bore deposit in Australia. The Berlin Project shares many characteristics
with the Nolans Bore deposit.?

2 Assay results ? lbs/st is an abbreviation for
pounds per short ton. 1 short ton = 2,000lbs or 0.907 metric tonnes. Potential quantity and grade are conceptual in
nature. There has been insufficient exploration to define a mineral
resource at the Berlin Project to date and it is uncertain if further
exploration will result in the target being delineated as a mineral
resource.
Mineralization
The mineralized unit at Berlin is a sedimentary layer that lies beneath an organic-rich, black shale that is Cretaceous in age
(Figure 2). The mineralized layer changes in composition from
fine-grained sandstone that transitions laterally
through carbonate-bearing siltstone to carbonate rock. Mineralization
lies at the top of this variable unit..
Microscopic study of drill core samples shows that the majority of the
phosphate occurs as fine, crystalline fluorapatite (Ca5(PO4)F) masses in the sandstone,
carbonate-bearing siltstone and carbonate rock. Most of the metals of
potentially economic interest occur as phosphate minerals, or are associated
with the fluorapatite.

Dr. Richard
Spencer, President & CEO of U3O8 Corp., a
Qualified Person within the definition of that term in NI 43-101 of the
Canadian Securities Administrators, has supervised the preparation of, and
verified the technical information in this release.
(1) The Berlin resource estimate is
historical and is reported in Castano, R. (1981), Calcul provisoire des reserves geologiques de Berlin, sur la
base des resultants des sondages, unpublished Minatome report, 15p. There has been insufficient
exploration work completed to verify the historic estimate. U3O8 Corp. is
not treating the historical estimate as current mineral resources and it should
not be relied upon or considered a NI 43-101 compliant resource. The majority
of the prior exploration on the Berlin Project was conducted by the French
company, Minatome, between 1978 and 1981 during which
time 11 widely-spaced bore holes were drilled, 20 trenches were dug and three adits were excavated. The historic estimate was
generated on the southern 4.4km of a 10.5km long syncline (Figure 1). Historic
data from trenching shows that anomalous grades of uranium continue along strike
to the north.
