MONTREAL, QUEBEC--(Marketwired - June 1, 2015) - Argex Titanium Inc. (TSX:RGX)

THIS NEWS RELEASE IS INTENDED FOR DISTRIBUTION IN CANADA ONLY AND IS NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the "US. Securities Act") or any state securities laws and may not be offered or sold within the United States or to US. Persons unless registered under the US. Securities Act and applicable state securities laws or an exemption from such registration is available.

Argex Titanium Inc. (TSX:RGX) ("Argex" or the "Corporation"), an emerging producer of high-grade titanium dioxide (TiO₂) is pleased to announce that it has appointed a syndicate of agents co-led by GMP Securities L.P. and Euro Pacific Canada Inc. (together, the "Co-Lead Agents") and including Cantor Fitzgerald Europe, Cormark Securities Inc. and Desjardins Securities Inc. (together with the Co-Lead Agents, the "Agents") as its Agents to sell units (the "Units") of the Corporation at a price of $0.37 (the "Offering"). Each Unit will be comprised of one share of the common share of the Corporation (a "Common Share") and one common share purchase warrant (a "Warrant"), each entitling the holder thereof to acquire a Common Share at a price of $0.4625 for a period of 48 months from the closing of the Offering.

The Corporation will grant the Agents an option to purchase such additional number of (i) Units (the "Over-Allotment Units"), each Over-Allotment Unit being comprised of one Common Share and one common share purchase warrant (the "Over-Allotment Warrant"), (ii) Over-Allotment Warrants, or (iii) any combination of Over-Allotment Units and Over-Allotment Warrants not exceeding 15% of the number of Units issued pursuant to the Offering, exercisable up to 30 days from and including the closing date to cover over-allotments, if any, and for market stabilization purposes (the "Over-Allotment Option").

The Units will be offered by way of a short form final prospectus to be filed in the Provinces of Alberta, British Columbia, Ontario and Québec. A preliminary prospectus in respect of the Offering was filed earlier today. The short form prospectus will also qualify the grant of the Over-Allotment Option and the distribution of the Over-Allotment Units and the Over-Allotment Warrants. The Offering is expected to close on or about June 17, 2015, subject to the approval of the Toronto Stock Exchange and the satisfaction of other customary closing conditions.

The net proceeds of the Offering will be used to initiate Front End Engineering and Design ("FEED/FEL3"), engineering associated with long lead items and for general corporate purposes before commencing the construction of Argex's first commercially sized TiO2 plant in Valleyfield, Quebec (the "Plant").

The Corporation expects that both the FEED/FEL3 and the construction phase of the Plant will be led by Tecnicas Reunidas Group, an international general contractor engaging in the engineering, design and construction of various types of industrial facilities for a broad spectrum of customers throughout the world.

"This Offering allows Argex, in coordination with our world class construction contractor and equipment vendors, to advance towards the construction plan of our Plant with all their wealth of experience", commented Roy Bonnell, President and CEO of Argex. "Once the FEED/FEL3 is completed, Argex will have strategically addressed cost structure to a point where we open up new financing, licensing, royalty and/or other strategic alternatives."

A non-controlling shareholder of the Corporation that holds more than 10% of the outstanding common shares of the Corporation has indicated its intention to subscribe for 25% of the Offering. Such non-controlling shareholder is a related party within the meaning of Multilateral Instrument 61-101- Protection of Minority Security Holders in Special Transactions ("MI 61-101"). Consequently, the participation of such non-controlling shareholder in the Offering constitutes a Related Party Transaction within the meaning of MI 61-101 requiring the Corporation, in the absence of exemptions, to obtain a formal valuation for, and minority shareholder approval of, the Related Party Transaction. The Corporation has determined that an exemption is available from the formal valuation requirements under MI 61-101, specifically under Section 5.5(a) which provides that at the time the transaction is agreed to, neither the fair market value of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involves related parties, exceeds 25% of the Corporation's market capitalization. The Corporation has determined that an exemption is also available from the minority shareholder approval requirements using the corresponding exemption under Section 5.7(a) of MI 61-101 on the same basis.
