(TSX VENTURE: UWE) a Canadian-based company focused on exploration and resource expansion of uranium and associated commodities in South America, reports assay results from a further four bore holes and three trenches completed in the Berlin Project in Caldas Province, Colombia. The Berlin Project is a sediment-hosted, multi-commodity prospect with a historic resource(1) of 12.9 million tonnes at an average grade of 0.13% U3O8 (38 million pounds ('mlb') U3O8) estimated on the southernmost 4.4 kilometres ('km') of a 10.5km long mineralized trend. This historic work did not include estimates for commodities other than uranium.

Infill Drilling to Commence Towards Increasing the NI 43-101 Resource

TORONTO, ONTARIO -- (Marketwire) -- 01/20/11 -- U3O8 Corp. (TSX VENTURE: UWE), a Canadian-based company, focused on exploration and resource expansion of uranium and associated commodities in South America, reports drill results that extend uranium mineralization to 900 metres ('m') in length along the Aricheng West structural corridor in the Kurupung Batholith in Guyana (Figure 1). Scout drilling shows that the Aricheng West area is one of nine consistently mineralized zones identified to date in the Kurupung uranium system. Mineralization remains open at depth and along strike on all structures. Aricheng West is scheduled to be the first of three uranium-bearing structures to undergo infill drilling, starting in March, towards the goal of increasing the current National Instrument 43-101 ('NI 43-101') resource estimate to 20 to 25 million pounds ('mlb')(1) on the Kurupung Project by the end of 2011.
