Caledonia Announces the Adoption of a Shareholder Rights Plan

TORONTO, ONTARIO--(Marketwire - April 14, 2008) - Caledonia Mining Corporation ("Caledonia")
(TSX:CAL)(OTCBB:CALVF)(AIM:CMCL) today announced that its Board of Directors has adopted a Shareholder Rights
Plan (the "Rights Plan") effective immediately.

The Rights Plan is subject to the approval of the Toronto Stock Exchange and must be ratified by shareholders
at the Special and Annual General Meeting to be held on May 16, 2008, failing which it will cease to have
effect. Subsequent to ratification by Caledonia shareholders, the Rights Plan will thereafter be in effect for
an initial term of three years and is subject to reconfirmation by shareholders at the third annual meeting
held after each confirmation.

"The adoption of a Rights Plan is intended to help protect our shareholders and is designed to ensure that they
will receive fair and equal treatment in the event of any take-over bid" stated Caledonia's President, Stefan
Hayden. Caledonia is not aware of any specific take-over bid for the Corporation in process or currently being
contemplated.

The Rights Plan is designed both to encourage the fair and equal treatment of Caledonia's shareholders in
connection with any potential take-over bid and to ensure that Caledonia's shareholders and its Board of
Directors, in compliance with securities laws, have sufficient time to consider whether there are other options
that would more effectively maximize shareholder value. The Rights Plan cannot be utilized to deny shareholders
the opportunity to tender into any tender offer and is not designed to entrench management or Caledonia's
Board. The terms of the Rights Plan are similar to those in rights plans recently approved by shareholders of
other Canadian corporations.

The Rights issued under the Rights Plan become exercisable when a person, together with any parties related to
it, acquires or announces its intention to acquire, 20% or more of the Corporation's outstanding common shares
without complying with the "Permitted Bid" provisions of the Rights Plan or without approval of Caledonia's
Board of Directors. Should such an acquisition occur each Right would entitle a holder, other than the
acquiring person or persons related to it, to purchase common shares of Caledonia at a significant discount to
the then current market price. A "Permitted Bid" is a bid made to all Caledonia shareholders that is open for
at least 60 days. If at the end of the 60 day period more than 50% of Caledonia's then outstanding common
shares, other than those common shares owned by the party making the bid and certain related persons, have been
tendered to the bid, such party may take up and pay for the common shares but must extend the bid for a further
10 business days to allow other shareholders to tender.

The Rights issued under the Rights Plan will initially attach to and trade with Caledonia's common shares and
no separate certificates will be issued unless an event triggering these Rights occurs. A copy of the Rights
Plan will be filed on SEDAR (www.sedar.com).
