U3O8 Corp. and Minexco Minerals Corp. Enter Into Agreements for Gold Exploration in Guyana

TORONTO, ONTARIO -- (Marketwire - March 26, 2012) - U3O8 Corp. (TSX VENTURE: UWE), a Canadian-based company focused on exploration and resource expansion of uranium and green commodities in South America, has signed a definitive agreement (the "Agreement") in which Minexco Minerals Corporation ("Minexco"), a private company based in the British Virgin Islands, will acquire non-core exploration properties in Guyana from U3O8 Corp. This transaction will result in the consolidation of exploration properties around Minexco's Tamakay gold concession. The principal targets in the consolidated exploration area are gold and potential for gold-copper deposits.

"We are delighted to partner with Minexco, a dynamic young company, to consolidate our non-core exploration assets with Minexco's high-potential gold property in a very prospective part of Guyana that lies adjacent to Sandspring Resources Ltd's Toroparu gold-copper deposit with Measured and Indicated resources of 6 million ounces and Inferred resources of 4 million ounces," said Dr. Richard Spencer, U3O8 Corp's President and CEO. "Our shareholders will gain exposure to Minexco's gold property and to early-stage targets that show potential for gold-copper deposits while U3O8 Corp. remains focused on rapid uranium resource growth on our lead projects in Colombia, Argentina, and Guyana."


Transaction highlights include:

- Minexco will issue up to nine million shares (approximately 13% of shares outstanding) to U3O8 Corp. at a deemed price of Cdn$0.30 per share (the "Minexco Shares") in consideration for seven grassroots concessions being transferred to Minexco.

- U3O8 Corp. may acquire up to an additional $1.2 million worth of Minexco Shares or units in subsequent financings for a period up to 18 months from the effective date of the Agreement (or earlier in the event of a completion of an initial public offering by Minexco).

- Minexco will finance the exploration within an area of interest, which has been jointly defined by the two parties to comprise Minexco's Tamakay Gold Project and U3O8 Corp's seven non-core properties. Exploration will be carried out by a unit of U3O8 Corp's Guyana team on a contract basis. U3O8 Corp's core exploration team will continue to drive its uranium program forward in Guyana.

- Dr. Richard Spencer, U3O8 Corp's President and CEO, has been appointed to Minexco's board. U3O8 Corp. will also have a preferential right to participate in future financings undertaken by Minexco, as long as U3O8 Corp. continues to hold at least 10% of Minexco's Shares outstanding.

- Upon completion of 5,000 metres of drilling within the area of interest, Minexco shall issue warrants to U3O8 Corp. to acquire 5% of Minexco's Shares outstanding on a fully diluted basis. Each warrant will be exercisable for two years.
