Baja Mining Announces First Concrete at Boleo and Provides Construction Timeline

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 11, 2011) - Baja Mining Corp. ("Baja or the "Company") (TSX:BAJ)(OTCQX:BAJFF) is pleased to announce first concrete has been poured at its 70% owned Boleo copper-cobalt-zinc project ("Boleo"), located near Santa Rosalia, Baja California Sur, and provide an update on progress at Boleo since completion of project funding in November 2010.

In January 2011, the Company and its subcontractors erected two cement batch plants near site in order to prepare all concrete for construction, with each batch plant able to produce 70m3 of concrete per hour. First concrete poured on March 30, 2011 initiated construction of the six counter current decantation ("CCD") high-rate thickeners (each thickener is 60 metres in diameter). The CCD thickener tanks will require 14,000m3 of concrete. Total concrete required at site amounts to 70,000m3. The Company is also in the process of moving approximately 5.3 million cubic meters of surface material at the process plant construction site.

The first quarter of 2011 saw much progress at site. Since year-end, more than 150+ full time permanent employees have been hired through the Company's Mexican service subsidiary and are now in training in various departments including mining, environment and health and safety. A job fair was held jointly between the Company's Mexican project company and the state and federal government of Mexico. Over 700 people attended the job fair, with over 400 local applications received. The workforce at Boleo will increase to 2,500 through construction, with 1,000 full time permanent positions continuing through operations.

"We are pleased to have first concrete poured on schedule at Boleo. This marks an important milestone in the development of the project," said Baja's President and CEO, John Greenslade. "This milestone provides the foundation for the balance of construction at our flagship project and for continued creation of stakeholder value."

The Company's construction timeline for the balance of 2011 is as follows:

Q2 2011 (April-June)

  • Commence surface mining at site (surface mining equipment received in March 2011)
  • Receive initial power generators at site providing 7.5MW of power to site

Q3 2011 (July-September)

  • Receive first underground mining equipment including underground batch haulage machines
  • Initiate construction of Marine Terminal for operations
  • Initial power plant to become operational
  • Commence underground mining
  • Final phase of construction camp to be completed

Q4 2011 (October – December)

  • Substantial completion of engineering
  • Arrival of process plant grinding mills and scrubbers

In addition, investigations continue into manganese recovery options at Boleo. The manganese metal production test work reported previously has continued at the University of British Columbia (UBC). In addition to UBC's manganese metal production test work, studies are underway to identify suitable locations for a manganese metal refinery, should a subsequent feasibility study support such a decision. Marketing activities have been initiated to identify and secure off take commitments for manganese carbonate and/or manganese metal.

2012 milestones will include completion of the Marine Terminal for operations; completion of the copper circuits. Commissioning and production of copper is scheduled for the first quarter of 2013, with cobalt and zinc circuits to follow towards the middle of 2013.

The Company will provide updates as progress continues at site. Updated pictures and videos of construction and special events are posted frequently on Baja's website.
