U3O8 Corp. Announces C$400,000 Non-Brokered Private Placement

In the event that subscriptions received for the Financing based on available prospectus exemptions exceed gross proceeds of C$400,000, the Company may increase the size of the Financing to 2,000,000 Units and gross proceeds of C$500,000.

Available Prospectus Exemptions to Subscribers

The Financing will be conducted pursuant to available prospectus exemptions including sales to accredited investors, close friends, family and business associates of directors and officers of the Company, as well as to existing shareholders of U3O8 Corp. by relying on the existing securityholder prospectus exemption (the "ESPE"), adopted by the Ontario Securities Commission (the "OSC") on February 5, 2015.

Existing shareholders who would like to participate in the financing through the provisions of the ESPE must comply with the following:

Each shareholder who qualifies to purchase shares under the ESPE rules may purchase up to C$15,000 of the Company's Common Shares in any twelve-month period. Any qualifying shareholder that makes a declaration on the subscription form that he or she has obtained advice from a financial advisor in regard to the purchase of the Company's Common Shares will not be subject to the C$15,000 ceiling. Due to associated legal, regulatory and administration costs, the Company requests that subscriptions be for a minimum of C$1,000 per shareholder.

In accordance with the ESPE, the Company confirms there is no material fact or material change related to the Company that has not been generally disclosed and that the Company's "core documents" and "documents", as defined under applicable securities laws, do not contain a misrepresentation.

If the Financing is over-subscribed, it is possible that a shareholder's subscription may not be accepted by the Company even though it is received.

This news release does not constitute an offer of securities for sale in the USA. The securities being offered have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and such securities may not be offered or sold within the USA absent USA. registration or an applicable exemption from USA registration requirements.

Use of Proceeds

Proceeds of the Financing will be used for the completion of metallurgical test work on the Company's Laguna Salada uranium-vanadium deposit in Argentina, for general corporate and administrative purposes, and to enable the Company to consider exercising its right to maintain its 39% holding in the private frac sand company, South American Silica Corp. ("SAS"), should SAS undertake a private placement in light of positive developments in the frac sand industry.

The Company would like to clarify that the "Berlin Project" on which three geologists were recently killed by guerillas in Colombia, is not U3O8 Corp.'s Berlin Project. However, U3O8 Corp.'s Board of Directors and Management have taken note of the recent security incidents in Colombia and are considering various options.

Finders' Fees

Eligible finders who introduce an investor to the Financing will be paid a commission of 7% of the value of the client's investment in cash and 7% of the value of the client's investment in broker warrants (the "Broker Warrants"). The Broker Warrants will be exercisable into Common Shares of the Company at C$0.40 and will be valid for a period of 24 months from the date of closing of the Financing.

Related Party Transactions

Richard Spencer (CEO of the Company) and John Ross (CFO of the Company) are expected to participate in the Financing (the "Insider Participation") and their participation will constitute a related party transaction within the meaning of Multilateral Instrument 61-101 ("MI 61-101"). In the absence of exemptions, the Company would need to obtain a formal valuation for, and minority shareholder approval of, the related party transaction. The Company intends to rely on the exemptions from the valuation and minority shareholder approval requirements of MI 61-101 contained in Sections 5.5 and 5.7 of MI 61-101 in respect of the Insider Participation.

Residents of the USA

Under USA regulations, 35 US non-accredited investors may participate in the Financing. There is no limit on the number of accredited investors eligible to subscribe in the Financing from the USA.

All securities issuable pursuant to the Financing will be subject to a statutory four (4) month hold period.

About U3O8 Corp.

U3O8 Corp. is focused on exploration and development of deposits of uranium and battery commodities in South America.

The Company's mineral resources estimates were made in accordance with National Instrument 43-101, and are contained in the following deposits:

• Laguna Salada Deposit, Argentina — a PEA shows this near surface, free-digging uranium-vanadium deposit has low production-cost potential;

• Berlin Deposit, Colombia — a PEA shows that Berlin also has low-cost uranium production potential due to revenue that would be generated from by-products of phosphate, vanadium, nickel, rare earths (yttrium and neodymium) and other metals that occur within the deposit; and
