Vancouver, October 9, 2014 – Baja Mining Corp. (TSXV:BAJ – OTCQX: BAJFF) (“Baja”) is pleased to announce that Minera y Metalúrgica del Boleo S.A. de C.V. (“MMB”) has appointed Sang Bum Lee as Chief Operating Officer following the death of Kyoung Jin Park. Mr. Lee will be responsible for directing the Boleo construction completion activities, including commissioning and start-up, and managing the operation of the Boleo Project.

Mr. Lee has had a long and successful career in the non-ferrous metals (zinc, lead and precious metals) industry gained in Korea, Australia, Europe and the United States in various positions ranging from technical process engineering, plant construction, production management, and commercial and global business management. He worked for 30 years within the Korea Zinc Ltd. organization, a leading global supplier of zinc metal products and one of the biggest non-ferrous metals producers in the world, where he retired as Managing Director and CEO of Sun Metals Corporation Pty Ltd, a wholly-owned subsidiary and major multi-million dollar zinc investment in Australia. Following his retirement from Korea Zinc, Mr. Lee acted as a technical and commercial adviser to Korean and Australian engineering and metal production companies. Most recently and until August 2014, Mr. Lee was the President of Sangdong Mining Corp, which is developing the Sangdong tungsten/molybdenum project in South Korea that hosts one of the largest tungsten resources in the world, and was the leading global tungsten producer for more than 40 years prior to closure in 1992.

Tom Ogryzlo, Interim CEO of Baja commented, “We are pleased that MMB has been able to quickly fill the critical role of Chief Operating Officer with such a qualified manager as Mr. Lee. Under the difficult circumstances of replacing Mr. Kyoung Jin Park at this stage of the project, Mr. Lee’s experience and leadership will be invaluable. I welcome Mr. Lee to the Boleo Project and wish him success with the start-up of production.”

In addition, Baja is pleased to report that it has been confirmed by MMB, as previously indicated by

MMB, that damage to the Boleo site caused by Hurricane Odile was minimal. As a result, MMB has

further advised Baja that it currently expects to produce first copper by the end of October 2014.
