U3O8 Corp. Adopts Advance Notice By-Law

TORONTO, ONTARIO -- (Marketwired) -- 05/13/13 -- U3O8 Corp. (TSX: UWE)(OTCQX: UWEFF), a Canadian-based company focused on exploration and resource expansion of uranium and associated commodities in South America, has adopted a new by-law that requires advance notice to U3O8 Corp. when director nominations are made by shareholders other than through a requisition for a meeting or shareholder proposal, in each case in accordance with the Business Corporation Act (Ontario).

U3O8 Corp. believes that this advance notice by-law is in the best interests of the company and shareholders as it will ensure that an orderly nomination process is observed and that shareholders are well-informed about director nominees in advance of shareholder meetings.

Among other things, the advance notice by-law fixes a deadline by which shareholders must both notify U3O8 Corp. of director nominations prior to any annual or special meeting of shareholders where directors are to be elected and provide information about the proposed nominee that a shareholder must include in the notice for it to be valid.

In the case of an annual shareholder meeting, notice to the company must be made not less than 30 nor more than 65 days prior to the date of the annual meeting, provided that in the event that the annual meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting was made, notice may be made not later than the close of business on the 10th day following such public announcement.

In the case of a special meeting of shareholders (which is not also an annual meeting), notice to the company must be made not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made.

The policy is effective immediately and will be placed before U3O8 Corp's shareholders for confirmation at the company's annual general and special meeting of shareholders on June 26, 2013.

About U3O8 Corp.

U3O8 Corp. is an advanced exploration company focused on exploration and resource expansion of uranium and associated commodities in South America. From 2010 to 2012, U3O8 Corp's uranium resources grew 7-fold with three deposits in compliance with National Instrument 43-101 ("NI 43-101") in Colombia, Argentina and Guyana comprising of:

--  Berlin Deposit, Colombia - its flagship project, which a recent PEA
    shows Berlin could be a zero cash cost uranium producer thanks to
    revenue from by-products of phosphate, vanadium, nickel, rare earths
    (yttrium and neodymium) and other metals occurring in the same deposit;
--  Laguna Salada Deposit, Argentina - a near surface, free-digging uranium,
    vanadium deposit that is potentially amenable to low-cost mining and
    processing methods; and
--  Kurupung Deposit, Guyana - an initial uranium deposit in a large
    emerging uranium district.
