U3O8 Corp's Infill Drilling Confirms Continuity of Uranium & Multi-Commodity Mineralization Through the Southern Part of the Berlin Project, Colombia Trench Results Continue to Show Potential Along the 10.5km Mineralized Trend

TORONTO, ONTARIO -- (Marketwire) -- 10/27/11 -- U3O8 Corp. (TSX VENTURE: UWE) a Canadian-based company focused on exploration and resource expansion of uranium and associated commodities in South America, reports assays from a further 17 bore holes in the 19,000 metre ('m') infill drilling program completed in the southern part of the Berlin Project, Colombia, as well as from additional trenching in the northern part of the mineralized trend. These data are being incorporated into the first National Instrument 43-101 ('NI 43-101') resource estimate undertaken on the property since the historic resource1 of 12.9 million tonnes at an average grade of 0.13% U3O8 (38 million pounds ('mlb') U3O8). The historic resource was estimated on the southernmost 4.4 kilometres ('km') of a 10.5km long mineralized trend and did not include estimates for other commodities that occur with the uranium.

(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in Castano, R. (1981), Calcul provisoire des reserves geologiques de Berlin, sur la base des resultants des sondages, unpublished Minatome report, 15p.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 and it should not be considered a NI 43-101 compliant resource. As the 38mlb U3O8 historic estimate is based on only 11 widely-spaced drill holes, 20 trenches and three adits, it is regarded by U3O8 Corp. as merely an indication of the uranium resource potential of the southernmost 4.4km of a 10.5km long syncline (Figure 1). U3O8 Corp. has now completed an infill drilling program with the aim of defining a mineral resource at Berlin.

'U3O8 Corp's drilling has shown remarkable consistency of the uranium-bearing layer in the southern part of the Berlin Project, and we have intersected excellent intervals including 8m at 0.12% U3O8 and 6.7m at 0.13% U3O8. Not only are the uranium grades predictable, but the same can be said for the suite of potential by-products including phosphate, vanadium, rare earths and other metals,' said Dr. Richard Spencer, President and CEO of U3O8 Corp. 'The infill drilling program has now been completed towards our aim of generating a maiden, interim NI 43-101 resource estimate on the southernmost 3km of the Berlin Project by the end of 2011. In addition, further trench results from the northern part of the 10.5km mineralized trend highlight the potential of the Berlin Project to contain a resource substantially in excess of the historic resource.'

(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.

U3O8 Corp. has now completed the planned exploration and infill drilling program of 82 bore holes (18,547m) that was designed to define an initial NI 43-101 resource on the southern part of the Berlin Project. Assays from the 58 drill holes press released so far confirm excellent continuity of mineralization in the fertile layer at Berlin as illustrated in the uranium grade-thickness map (Figure 6).

The mineralized layer in the Berlin Project occurs as a canoe-shaped fold that, in cross-section, has an asymmetric 'U'-shape (Figures 3, 4 and 5). In order to visualize the distribution of mineralization, the layer is shown as an 'unfolded', flat sheet in Figure 6. This diagram shows the distribution of each pierce point, the point at which each bore hole intersected the mineralized layer, as well as the distribution of trenches that were excavated where the layer comes to surface. The uranium grade-thickness value (the grade of the mineralized interval multiplied by its thickness) of each pierce point and trench location was used to generate a contour map that illustrates the continuity of grade through the project area.
