Baja Mining Provides Update

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/13/12 -- Baja Mining Corp. ("Baja") (TSX: BAJ)(OTCQX: BAJFF) provides the following update.

In May, Baja retained BMO Capital Markets to assist in considering financing options and possible sources of funding. Non-disclosure agreements were signed by a number of interested parties, who were granted access to Baja's data room and attended management presentations. A draft independent engineering report prepared by SRK was recently provided to parties participating in the BMO process.

Baja has not yet received any proposals as a result of the BMO process. A number of parties continue with their reviews, including several parties who only recently signed non-disclosure agreements and obtained data room access and the draft SRK report and are in the early stages of reviewing the materials.

As previously advised, Baja's cash forecasts indicate that it will have insufficient funds to maintain current levels of effort beyond August 1, 2012.

Baja previously announced its preliminary view that projected operating expenses at the Boleo Project have risen significantly, driven by increased mining costs, higher sulfur costs, higher diesel volumes and costs, and higher labour expense (rate and time).

Management has now advanced its review of the anticipated operating costs at the Boleo Project, and currently estimates operating costs at between $50 - $60 per ore tonne
