MORE �OFF-SCALE� RADIOACTIVE BOULDERS AND MORE CLAIMS LOCATED AT FISSION/ESO PATTERSON LAKE URANIUM PROPERTY

ESO Uranium Corp. (TSX-V: ESO), (the �Company� or �ESO�) and its 50% Joint Venture (JV) partner Fission Energy (TSX-V: FIS), announce the completion of its boulder prospecting and radon survey program:

• An additional twenty radioactive boulders and hot spots were discovered on the Patterson Lake South Property claims for a total of seventy-four.
• Of this latest total, forty-two or 57% produced "off-scale" (>9,999 counts per second [cps]) radioactive readings, as measured by hand held Exploranium GR-110G total count gamma-ray scintillometers.
• The uranium boulder field now exceeds 4km in its longest N-S dimension and is up to 0.9 kms in its E-W dimension.
• Four claims comprising an area of 12,217 ha (~30,000 acres) have been acquired by staking, bringing the combined land holdings to twelve claims totalling 25,450 ha (~63,000 acres), covering the SW extension of the Derkson Conductor Corridor.

 Samples have been submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis, which include a 63 element ICP-OES, uranium by fluorimetry (partial digestion). Assays will be reported when available.

A summary of the boulder and soil descriptions, in addition to a map updating the new claim boundaries at Patterson Lake can be reviewed on the Company�s website: www.esouranium.com

 The Patterson Lake Property is accessible by all weather Highway 955, which runs north to the former Cluff Lake mine, (>60M lbs of U₃O₈ produced). Several of the deposits that made up the Cluff Lake Mine were located by following up uranium boulder fields significantly smaller than the one discovered by the JV. The next challenge for the JV is to locate and define the source of its uranium boulders If the source is located it will then be necessary to determine its economic potential. Work will also be undertaken to assess the possibility that the boulder field itself could be an economic deposit of uranium mineralization.
