Baja Mining Provides Update on Stage II Funding Decision

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/04/12 -- Baja Mining Corp. ("Baja") (TSX: BAJ)(OTCQX: BAJFF) reports that it has been informed by the Korean consortium (the "Consortium") that the Consortium was unable to make a decision regarding Stage II funding by August 30, 2012 (as previously announced by Baja on July 26, 2012), but continues its current due diligence and transition planning process toward that decision.

The Consortium continues to evaluate whether to contribute the additional funding necessary to bring the Boleo project to completion. The Consortium is also discussing with the lenders the re-activation of Minera y Metalurgica del Boleo S.A. de C.V. ("MMB") credit facilities.

The standstill agreement with MMB's lenders remains in effect until September 15, 2012. The Consortium has the option under the current standstill agreement to extend the standstill period by committing further funds necessary to fund MMB operations during such extension and as agreed with MMB's lenders.

Baja has been advised that the Consortium will elect whether to proceed with Stage II funding upon completion of its due diligence. Baja has agreed to waive the August 30, 2012 decision date referenced in the term sheet in order to provide the Consortium with the opportunity to complete its diligence.
