Highlights from Winter 2006 Drill Season

Preliminary Drill Holes intersected Uranium Mineralization and Identified a structural zone more than 700 metres in length that apears to be prospective for additional mineralization.

CLU-01: 0.48% U3O8 over 1.5M

CLU-07: 0.17% U3O8 over 7M

including 1M of 0.82% U3O8 as well as 0.20% U3O8 over 2M

ESO Uranium Corp. has varied interests in over 985,500 acres within the Athabasca Basin, Saskatchewan.

The Athabasca Basin is the world's most important uranium producing district, accounting for more than 30% of global primary uranium supply. All current production in the Basin is from "unconformity - type" deposits.

Since 1968, eighteen deposits totaling almost 1.5 billion pounds of uranium have been discovered in the area, including the rich McArthur River Mine with total reserves of 419 million lbs at an average grade of 24.72% U308. The earlier discoveries, including Rabbit Lake and Key Lake were near surface and found through prospecting and ground geophysics. Later discoveries such as McArthur River and Cigar Lake, were located using deep penetrating geophysical surveys. Cigar and McArthur were found using a range of methods including: boulder sampling, geochemistry, airborne and ground geophysics with targets tested by drilling.

As the overall dimensions of high grade deposits are very small (ie. ½ of reserves at McArthur River are contained in a zone measuring: 70 meters long x 70 meters deep x 30 meters wide) there is excellent potential to find more "blind" deposits with the enhanced geophysical systems available today.
