Toronto and Johannesburg - First Uranium Corporation (TSX:FIU.UN), (JSE:FUU) (ISIN:CA33744R5087) ("First Uranium" or "the Corporation") announced that today the Implementation Date occurred, as defined in the agreement (the "AGA Agreement") dated March 2, 2012 for the sale, indirectly, of all of the shares of Mine Waste Solutions (Proprietary) Limited ("MWS"), owner of the tailings recovery project in South Africa, to AngloGold Ashanti Limited.
At this juncture, certain documents relating to the discharge of the security held for the benefit of the 7% secured convertible notes due March 31, 2013 (the "Canadian Notes") issued by First Uranium, the 11% secured convertible notes due March 31, 2013 (the "Rand Notes") issued by MWS, and the Gold One US$10 million loan facility, have been registered by the appropriate deeds office releasing all security in the MWS assets.
Today, Computershare Trust Company of Canada and Computershare Investor Services (Proprietary) Inc., as Purchase Price Stakeholders will pay: (i) to BNY Trust Company of Canada, as trustee for the holders of the Canadian Notes, C$110 million, and to GMG Trust Company (SA) (Pty) Ltd. (or its agent), as trustee for the holders of the Rand Notes, ZAR418.6 million, (ii) to Gold One, US$10 million plus accrued interest; (iii) US$25 million to the warranty escrow agent; and (iv) the balance to First Uranium.
Trading in all of the issued and outstanding Canadian Notes (Symbol: FIU.NT; ISIN: CA33744RAC66 and CA33744RAD40) of First Uranium will be halted at the opening of trading on the TSX on July 31, 2012 (the "Redemption Date") and will be delisted at the close of business on July 31, 2012.
All of the issued and outstanding Canadian Notes have been called for redemption on the Redemption Date. The redemption price for each C$1,000 principal amount of Canadian Notes held will be C$1,000 (the "Redemption Price") and no interest is payable.
As the Canadian Notes trade in the book-entry only system of CDS Clearing and Depository Services Inc., holders need not take any action in order to receive their Redemption Price.
MWS has called for the redemption of the Rand Notes and a separate announcement in respect thereof has been issued on the JSE Limited's Stock Exchange News Service (SENS).
The Corporation expects that the sale of First Uranium Limited, owner of the Ezulwini mine, to Gold One International Limited, will be closed by the end of July 2012.
