U3O8 Corp's Infill Drilling Cuts 2m at 0.14% U3O8 & Further Confirms Continuity of Multi-Commodity Mineralization in the Southern Part of the Berlin Project, Colombia Metallurgical Results Being Corroborated

TORONTO, ONTARIO -- (Marketwire) -- 11/23/11 -- U3O8 Corp. (TSX VENTURE: UWE), a Canadian-based company focused on exploration and resource expansion of uranium and associated commodities in South America, reports on its Berlin Project in Colombia that:

--  assays from an additional five bore holes drilled in the infill program
    completed in the southern part of the project further confirm excellent
    continuity of uranium and multi-commodity mineralization;


--  positive, initial metallurgical test results are being corroborated for
    anticipated release in December, 2011; and


--  work is progressing well towards the completion, by year-end, of the
    first National Instrument 43-101 ('NI 43-101') resource estimate
    undertaken on the property since the historic 38 million pound ('mlb')
    uranium resource(1) was calculated in 1981.

(1) The Berlin historic resource of 12.9 million tonnes at an average grade of 0.13% U3O8 (38mlb U3O8) is reported in Castano, R. (1981), Calcul provisoire des reserves geologiques de Berlin, sur la base des resultants des sondages, Unpublished Minatome report, 15p. As the 38mlb U3O8 historic estimate is based on only 11 widely-spaced drill holes, 20 trenches and three adits, it should not be considered a NI 43-101 compliant resource. The historic resource is regarded by U3O8 Corp. as merely an indication of the uranium resource potential of the southern 4.4 kilometres ('km') of a 10.5km long syncline (Figure 1) containing the Berlin mineralization. The historic resource did not include estimates for other commodities. U3O8 Corp. has now completed an infill drilling program with the aim of defining an interim multi-commodity mineral resource on the southernmost 3km of the Berlin trend.

'U3O8 Corp's drilling continues to demonstrate remarkable continuity of uranium, vanadium, and phosphate mineralization, accompanied by a suite of other metals that constitute potential by-products, throughout the southern part of the Berlin Project,' said Dr. Richard Spencer, President and CEO of U3O8 Corp. 'Furthermore, our trenching has confirmed mineralization in the northern part of the 10.5km trend at Berlin, where we plan to extend drilling in 2012 with the aim of delineating a truly world-class deposit. Results of initial metallurgical test work on the recovery of the different commodities have also been received on a composite sample derived from five bore holes. These positive test results are currently being corroborated and confirmed in a second sample comprised of ore from an additional 10 bore holes, and we expect to release these metallurgical results in December, 2011.'

U3O8 Corp. has now completed the planned exploration and infill drilling program of 82 bore holes (18,685 metres) that was designed to provide sufficient detail for an initial NI 43-101 resource estimate to be undertaken on the southern 3km of the Berlin Project. Assays from the 63 drill holes disclosed so far confirm excellent continuity of mineralization in the fertile layer at Berlin. Results from six trenches in 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.

The mineralized layer in the Berlin Project occurs as a canoe-shaped fold that, in cross-section, has an asymmetric 'U'-shape (Figure 3). In order to visualize the distribution of mineralization, Figure 4 shows the layer as an 'unfolded', flat sheet and also marks the bore hole intercepts from which samples are currently undergoing metallurgical testing.
