    TSX: SDM
    Shares issued and outstanding: 166,232,179

    TORONTO and LONDON, April 16 /CNW/ - SouthernEra Diamonds Inc.
("SouthernEra" and the "Company") (TSX: SDM) announced today that it will not
be appointing a new nominated advisor for its AIM listing and as such, under
established AIM rules, trading of the Company's shares listed on AIM under the
symbol SRE, will be cancelled at 7:00 am on April 17, 2007.
    Due to an intended share exchange proposal made by Mwana Africa Plc
("Mwana") on March 16, 2007, the Company's nominated advisor for AIM,
Canaccord Adams Limited, immediately resigned from its advisory role due to
its relationship with Mwana. AIM has, since that date, suspended trading of
the Company's shares on that exchange.
    The Company advises any shareholders that would normally trade
SouthernEra shares on AIM to continue to do so on SouthernEra's listing on the
Toronto Stock Exchange under the symbol SDM.
