On April 20, 2004, Baja Mining Corp. (The “Company”) concluded the reverse takeover (“RTO”) of Mintec International Corporation, of Barbados, and consequently its wholly owned Mexican subsidiary Minera y Metalugica del Boleo S.A. de C.V. (“MMB”). MMB holds a 100% interest in the Boleo Copper-Cobalt-Zinc deposit on the Baja Peninsula, Mexico. Contemporaneous with the RTO we also concluded a $10 million equity placement.

Boleo Co-Cu  Project, Baja California Sur. The Boleo Property was an historic copper mine in Mexico – producing approximately 19 million tonnes of copper ore at an average grade of approximately 4.3% copper (of which the majority 13.2 million tonnes produced during the period 1886-1947 averaged 4.81% copper) during the period 1868 to 1972. Previous operators were unable to concentrate the minerals contained within the ore and accordingly the ore was direct smelted, accounting for the requirement for the high grade ore and resulting in material grading less than 3% copper either not being mined or backfilled in mined areas. No attempt was made to recover the contained cobalt or zinc (or other potential valuable constituents). Since 1992 approximately US$25 million has been spent on the Boleo Property to assess reserves and to develop modern techniques for the processing of the ore to extract the contained copper-cobalt –zinc, culminating in the issuance of a pre-feasibility study by by Batemen Engineering Pty Limited, of Perth, Western Australia, in February 2002 (the “Bateman Study”
