        --  Argex to acquire majority interest in privately-owned CTL
        --  CTL to grant license to Argex for the recovery of titanium
            dioxide (TiO2)

MONTREAL, Sept. 28, 2011 /CNW Telbec/ - Argex Mining Inc. (Argex) is pleased to announce that it has entered into a definitive Share Purchase Agreement with the shareholders of privately-owned Canadian Titanium Limited (CTL) to acquire a 50.1% ownership interest in CTL.  The consideration for the purchase of 50.1% of the outstanding shares of CTL will consist of payment by Argex to the selling shareholders of $1 million as well as 2 million Argex common shares.

'After extensive bench and miniplant testing, we are satisfied that the process has demonstrated the required level of performance to allow us to acquire a majority interest in CTL immediately,' stated Roy Bonnell, President and CEO of Argex.

CTL will grant Argex an exclusive license in the Province of Québec and a non-exclusive license for the rest of the world to use the licensed technology for the recovery of titanium dioxide (TiO(2)).  CTL will provide Argex with all of the know-how and information which is applicable to the licensed technology and products.  Argex will pay CTL a 2% royalty on its production of titanium dioxide (TiO(2)).

'We are very pleased with this acquisition intended to allow Argex to advance towards production with CTL's proprietary technology', said Mr. Bonnell, 'The CTL technology will allow Argex to go from mine to high-purity pigment-grade TiO(2) in one process. I believe this to be a game-changer in the industry.'

'Going forward with CTL and its team, we will continue to re-shape the industry through technological improvements and innovation creating additional revenue streams from the technology,' added Mr. Bonnell.

CTL is a private company which owns technology and underlying patents which Argex will use, through the License and Royalty Agreement, to process titanium-bearing ore, thereby creating a high-value product.

The transaction, which has been unanimously approved by the Boards of Directors of Argex and CTL, is subject to regulatory approval, including that of the TSX Venture Exchange, and customary closing conditions.  The Argex shares to be issued to the selling shareholders will be subject to a four-month 'hold period' under applicable securities legislation and the policies of the TSX Venture Exchange.

About Argex Mining Inc.

ARGEX MINING INC. has recently transitioned from a mining exploration company to a near-term producer of commodities that the world needs: Titanium Dioxide, Iron and Vanadium Pentoxide.  With a primary goal of advancing rapidly towards production, Argex has adopted a simple and low-risk strategy for the scale-up of its proprietary process that allows it to produce high purity TiO(2) directly from its 100%-owned deposit.

Additionally, Argex owns 100% of the Mouchalagane property, which is a large Labrador Trough iron ore property that represents further potential upside for Argex shareholders.
