Orosur Mining Inc

Orosur Mining Inc. ("OMI" or the "Company") (TSX: OMI) (AIM: OMI), the South American-focused gold producer and explorer, announces that the common shares of the Company will be listed and posted for trading at the opening on Monday May 14, 2012 on the TSX under the symbol “OMI”. The Company will be listed as an exempt issuer on the TSX and will therefore be exempt from the reporting requirements of Section 501 of the TSX Manual.

An application has been granted for the original listing in the Mining category of 81,800,896 common shares, of which 77,979,809 shares are issued and outstanding and 3,821,087 shares are reserved for issuance.

On March 29, 2000, the common shares of the Company were admitted for listing on The Canadian Venture Exchange Inc. (“CDNX”), a predecessor to the TSX Venture Exchange. In June 2002, the CDNX was acquired by the TSX as a wholly owned subsidiary. Accordingly the name of the CDNX was changed to the TSX Venture Exchange (“TSXV”), where the Company’s common shares trade under the symbol “OMI”. On December 15, 2004, the common shares of the Company were admitted for listing on the AIM Market of the London Stock Exchange (“AIM”) where they trade under the symbol “OMI”. The common shares will be delisted from TSXV on Monday May 14, 2012 upon commencement of trading on TSX.
