VANCOUVER, June 1 /CNW/ - Argentex Mining Corporation ("Argentex") (TSX-V: ATX, OTCBB: AGXM) is pleased to announce that it has agreed to the terms of a private placement with IFC, a member of the World Bank Group focused on private sector investments in developing countries.

In the mining sector, IFC provides equity and loan financing for exploration and mining companies to advance projects that have the potential to provide long term economic benefits to countries and local communities. IFC offers an integrated approach that combines financing with industry expertise and assistance in maximizing projects' social benefits while minimizing their environmental footprints.

IFC's proposed investment in Argentex contemplates that Argentex will sell to IFC 9,184,000 units (the "Units") at a price of Cdn $0.80 per Unit for gross proceeds of Cdn$7,347,200. Each Unit will consist of one common share of Argentex (each a "Unit Share") and one common share purchase warrant (a "Warrant"). Each Warrant will entitle the purchaser to purchase one additional common share of Argentex (each a "Warrant Share") at a price of Cdn$1.34 for a period of five years after closing.

Argentex anticipates that this private placement should close on or before July 31, 2010. Closing of this financing is subject to conditions, including IFC due diligence, approval by IFC's Board of Directors, approval of the TSX Venture Exchange and the negotiation and execution of definitive agreements.

"We look forward to having an experienced investor such as IFC make the largest single investment in our company's history," said Ken Hicks, President of Argentex. "IFC is a long term investor with an impressive track record of making successful equity investments in developing countries. Their value-added business approach to investment as well as their confidence in both the Argentex organization and our properties is very positive."

Except as specified in this press release, none of the securities to be offered or sold in this private placement have been or will be registered under the United States Securities Act of 1933, as amended (the "Act"), and none of them may be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Act.

Each of the Unit Shares and the Warrant Shares will be a "restricted security" under the Act and will be subject to a hold period of at least six-months from the date they are issued. In addition, these securities will be subject to a hold period of four months and one day after closing under applicable Canadian securities laws and the requirements of the TSX Venture Exchange. The Warrants will also be restricted securities subject to these restrictions but, in addition, these securities will be non-transferable by their terms during the first 30 months.

Argentex intends to use the proceeds of the private placement to fund exploration and pre-feasibility activities at its properties in the Patagonia region of Argentina, as well as for working capital and for general corporate purposes.
