U3O8 Corp. Files NI 43-101 Technical Report on the Uranium, Phosphate & Vanadium Resources on the Berlin Project, Colombia

TORONTO, ONTARIO--(Marketwire - March 5, 2012) - U3O8 Corp. (TSX VENTURE:UWE), a Canadian-based company focused on exploration and resource expansion of uranium and associated commodities in South America, reports the filing of the National Instrument 43-101 ("NI 43-101") Technical Report on the Berlin Project, Colombia, following the company's press release on January 18, 2012 that announced a maiden uranium, phosphate and vanadium resource estimate as follows:

Uranium Resource:

  • Indicated: 1.5 million pounds ("mlb") U 3O8 (0.6 million tonnes at a grade of 0.11% U3O8); and
  • Inferred: 19.9mlb U3O8 (8.1 million tonnes at a grade of 0.11% U3O8).

Contained in the same mineralized layer as the uranium resource, are inferred resources of:

  • Phosphate: 0.8 million tonnes (8.7 million tonnes at a grade of 9.3% P2O5); and
  • Vanadium: 97mlb V2O5 (8.7 million tonnes at a grade of 0.50% V2O5).

The NI 43-101 resource has been estimated on only the southernmost three kilometres ("km") of a 10.5km mineralized trend on the Berlin Project. The tightly constrained, continuous, tabular unit of the uranium-bearing layer at Berlin results in minimal change of the resource size at various uranium cut-off grades. For example, doubling the cut-off grade from 0.04% to 0.08% U3O8 results in only a 3% decline in the resource (Table 1). In addition, the other commodities, such as vanadium, phosphate and yttrium, generally occur in a thicker layer that extends beyond the uranium mineralized unit. This feature of the mineralization suggests the strong possibility of increasing the resource of the other elements at Berlin once mining and processing cost parameters have been defined; and thereafter, a cut-off value based on dollar rock-value will likely be used for resource estimation instead of a specific uranium grade as was used in the current resource estimate.

The plan for 2012 is to continue drilling with the goal of increasing the Berlin resource to 40 to 50mlb1 of uranium, while ongoing exploration drilling will aim to outline the size potential of the entire 10.5km mineralized trend. With an initial NI 43-101 resource estimated and positive metallurgical results defining efficient extraction of a suite of commodities at Berlin, a scoping study is planned to commence.

(1) A historic (non NI 43-101 compliant) resource of 12.9 million tonnes at 0.13% U3O8 (38mlb U3O8) was reported on Berlin in Castano, R. (1981), Calcul provisoire des reserves geologiques de Berlin, sur la base des resultants des sondages, Unpublished Minatome report, 15p. based on only 11 widely-spaced drill holes, 20 trenches and three adits, and is not 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 4.4km of the 10.5km long syncline. The historic resource did not include estimates for other commodities. U3O8 Corp. has now defined an initial multi-commodity NI 43-101 resource on just the southernmost 3km of the Berlin trend.

Table 1 - Uranium Resource Estimate Summary

A summary of the uranium resource estimated on the southern 3km of the 10.5km mineralized trend in the Berlin Project at various U3O8 cut-off grades is detailed below, which estimate is effective as of January 17, 2012. The recommended cut-off grade of 0.04% U3O8 has been used for the reported uranium resource.

The NI 43-101 Technical Report is dated March 2, 2012 and titled "Berlin Project, Colombia, National Instrument NI 43-101 Report", which is consistent with the resource announced in the press release dated January 18, 2012. The report can be viewed on SEDAR at www.sedar.com. The report was undertaken by Mr. Neil Inwood, a Fellow of The Australasian Institute of Mining and Metallurgy, who is employed by Coffey Mining Pty Ltd, and visited the Berlin site in May 2011. Mr. Inwood has sufficient experience which is relevant to the style of mineralization and type of deposit under consideration and to the activity which he is undertaking, to qualify as a Competent Person as defined in the 2004 Edition of the "Australasian Code for Reporting of Mineral Resources and Reserves" and as a "qualified person" fo r purposes of NI 43-101.
