Keefe Phase 1 Analytics Show Significant Uranium Indicators in Sandstone & Anomalous Uranium in Basement – Keefe Phase 2 Drilling Continues

March 28, 2012


VANCOUVER, March 28, 2012 /PRNewswire/ – Athabasca Uranium Inc. is pleased to
report that it has received the analytical results of its 2011 diamond
drilling program at the Keefe Lake Uranium Project in the Athabasca
Basin region of Saskatchewan. Five holes (1,645 metres total) were
completed in Phase 1 drilling conducted in November and December 2011,
with two holes encountering significantly anomalous alteration and
another containing chloritic alteration at various intervals below the
unconformity, a common feature found in the host rocks containing
uranium mineralization.

As previously reported in a release dated November 24, 2011, Hole AU4-1
intersected a large zone of alteration that started in the sandstone
column, and continued well into the basement. In addition to the
visible alteration in the sandstone, elevated levels of uranium
indicator metals have been identified, which include: Cobalt (up to 12
times background), Arsenic (up to 3 times background), Lead (up to 5
times background) and Nickel (up to 9 times background).

Samples from basement lithologies within Hole AU4-1 revealed elevated
levels of uranium (up to 155 ppm U) within a sheared/fractured granitic
pegmatite.  The basement of Hole AU4-1 consists predominantly of
quartzite with minor intervals of arkosic quartzite, semipelitic gneiss
and amphibolite.

The goals for the current Phase 2 drilling are two-fold.  The first
priority is to intercept the boundary of the quartzite unit where it
meets the unconformity in order to test a possible paleo-topographic
high that may have provided a conduit for mineralizing fluids. 
Quartzite ridges have recently been identified as an important feature
for localizing uranium mineralization at the unconformity; including
the McArthur River mine and the Phoenix Zone.

The second priority will be to test additional high-priority targets
from the regional seismic survey and other subsurface conductors on the

UAX President Gil Schneider commented: “We are extremely pleased with
the results from Keefe Phase 1 – we believe that the identification of
a quartzite lithology in addition to the uranium indicator metals in
the sandstone marks a significant milestone for the Keefe Lake
Project.  Our Phase 2 drilling, moving to its second hole at present,
will help to validate our theories for the Keefe area”.

Samples were analysed by SRC Geoanalytical Laboratories (an SCC ISO/IEC
17025: 2005 Accredited Facility) of Saskatoon for analysis, which
included a 16 element ICP-OES partial digestion, a 46 element ICP-OES
total digestion.  The uranium content above is uranium by fluorimetry
(partial digestion, ICP-OES).
