MONTREAL, Sept. 29 /CNW Telbec/ - Argex Mining Inc. ("Argex") (TSX-V: RGX) (FSE: ASV) (OTCBB: ARGEF) is pleased to announce that it has completed its previously-announced private placement by issuing an aggregate of 17,500,000 special warrants (each, a "Special Warrant") at a price of $0.30 per Special Warrant, for gross proceeds to Argex of $5,250,000.

Each Special Warrant entitles its holder to purchase, for no additional consideration, one common share (each, a "Common Share") and one common share purchase warrant (each, a "Warrant") of Argex.  Each Warrant will entitle its holder to purchase one additional Common Share at a price of $0.52 until September 29, 2014.

Argex intends to use the net proceeds from the private placement to fund ongoing metallurgical, engineering and development projects, and for working capital and general corporate purposes.  "The proceeds from this private placement will allow Argex to accelerate its engineering and scoping study work on the La Blache Project, which Argex intends to have ready for mini-plant work in 2011," said Michael Dehn, President and Chief Executive Officer of Argex.

Argex will file a prospectus with the securities commissions of certain of the provinces of Canada to qualify the Common Shares and Warrants issuable upon the exercise of the Special Warrants.  In the event that Argex fails to obtain a receipt for a final prospectus by January 30, 2011, each Special Warrant will entitle its holder to purchase, for no additional consideration, 1.1 Common Shares and 1.1 Warrants (in lieu of one Common Share and one Warrant).  The Special Warrants will be automatically exercised (if not previously exercised) on the earlier of January 30, 2011, and the fifth business day after a receipt has been issued for the final prospectus.

MGI Securities Inc. ("MGI") acted as agent for the private placement.  In connection with the private placement, Argex paid MGI a cash commission of $388,944 and issued non-transferable broker warrants to MGI and Wellington West Capital Markets Inc., entitling them to acquire a maximum of 1,750,000 units (each, a "Unit") of Argex at a price of $0.30 per unit until September 29, 2012.  Each Unit will be comprised of one Common Share and one Warrant.  Each Warrant will entitle its holder to acquire one additional Common Share at a price of $0.52 per Common Share until September 29, 2014.

As the date hereof there are 56,992,300 common shares of Argex issued and outstanding.  Under applicable securities legislation and the policies of the TSX Venture Exchange, the securities issued in the private placement are subject to a four-month hold period expiring on January 30, 2011.
