About U3O8 Corp.

U3O8 Corp. is a Canadian uranium exploration company based in Toronto,
Canada. Currently focused on exploration in the Roraima Basin area of
Guyana, South America, U3O8 Corp.'s primary business objective is to
explore, develop and acquire uranium projects in the Americas. The
Company is well funded with over $18 million held solely in cash and
Canadian chartered bank-backed Guaranteed Investment Certificates. At
current rates of exploration expenditure, the company expects to be
funded up until 2010.

U308 Corp. has exclusive uranium exploration rights in an area covering
approximately 1.3 million hectares that straddles the edge of the Roraima
Basin in Guyana. The company is advancing a two-pronged exploration
strategy that includes:

- Exploration for multiple uranium-bearing structures within structural
systems in the basement adjacent to the Roraima Basin with the concept
that the individual veins could potentially aggregate to a significant
total resource; and

- Exploration for unconformity-style uranium deposits at the base of the
Roraima Basin, which are similar to those of the prolific Athabasca Basin
in Saskatchewan.
