Argex adopts shareholder rights plan

MONTREAL, March 22, 2012 /CNW Telbec/ - Argex Mining Inc. ('Argex' or the 'Corporation') today announced that its Board of Directors has, at a meeting of the board held on March 22, 2012, approved the adoption of a shareholder rights plan (the 'Rights Plan') entered into with Canadian Stock Transfer Company Inc. as rights agent, effective March 22, 2012.

The purpose of the Rights Plan is to ensure that, in the context of a bid for control of Argex through an acquisition of the common shares of the Company (the 'Shares'), the Board of Directors has sufficient time to consider the bid and assess alternatives for maximizing shareholder value as it considers in its judgment to be in the best interests of the Corporation. Additionally, the Rights Plan gives shareholders an equal opportunity to participate in such a bid; gives them adequate time to properly assess the bid; and lessens the pressure to tender typically encountered by a securityholder of an issuer that is subject to a bid.

Argex's Board of Directors is not aware of any third party currently considering or preparing any proposal to acquire control of the Corporation.

The rights plan has not been approved by the TSX Venture Exchange and is subject to ratification by the shareholders of the Corporation at its annual and special meeting of shareholders anticipated to take place on June 26, 2012.

The Rights Plan is intended to encourage any bid to satisfy certain minimum standards designed to promote fairness. Under the Rights Plan, one right has been issued with respect to each of the Shares issued and outstanding as of the effective date. These rights will become exercisable only when a person, including any party related to it, acquires or attempts to acquire 20 percent or more of the outstanding Shares without complying with the 'Permitted Bid' provisions of the Rights Plan or without approval of Argex's Board of Directors.

A complete copy of the Rights Plan will be filed under the Corporation's profile on SEDAR at www.sedar.com.

About Argex Mining Inc.

ARGEX MINING INC. is 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 run-of-mine material from its 100% owned deposit.

The process is running continuously at the mini-plant in Mississauga, Ontario. The closed-loop process is environmentally friendly and produces minimal inert tailings.

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