Baja Mining Adopts Shareholder Rights Plan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 22, 2011) -Baja Mining Corp. ("Baja" or the "Company") (TSX:BAJ)(OTCQX:BAJFF) today announced that its Board of Directors has approved the adoption of a shareholder rights plan (the "Rights Plan"), which takes effect from today, Friday, April 22, 2011. The Rights Plan is similar to plans adopted by other Canadian companies, and has been adopted to ensure the fair treatment of shareholders in the event of any take-over bid for Baja's common shares.

The Rights Plan has conditionally been approved by the Toronto Stock Exchange and is subject to approval by Baja's shareholders at the 2011 annual general and special meeting, currently scheduled to be held on May 25, 2011.

The primary objectives of the Rights Plan are to provide shareholders with adequate time to properly evaluate any offer, and also to provide the Board of Directors with additional time to assess any offer and, if appropriate, to explore and develop alternatives for maximizing shareholder value. The Rights Plan in no way prohibits a change of control of the Company in a transaction that is procedurally fair to its shareholders. The approval of the Rights Plan by shareholders will not alter, diminish or reduce the fiduciary duties of the directors of the Company when faced with a potential change of control transaction or restrict the potential actions that might be taken by the directors in such circumstances. The adoption of the Rights Plan is not in reaction to any anticipated take-over bid, but rather as good practice for the protection of shareholders.

The full text of the Rights Plan is available on Baja's website at, on the SEDAR website at and on the U.S. Securities and Exchange Commission EDGAR database at
