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.
