BRISBANE, AUSTRALIA--(Marketwire - June 19, 2011) - The Directors of Orocobre Ltd. (TSX:ORL)(ASX:ORE) are pleased to announce that the Unit of Mining Environmental Management ("UGAMP") has approved the addenda to the Environmental Impact Statement for the Salar de Olaroz Lithium-Potash Project.

The addenda updated the previously approved Environmental Impact Statement with the results of the company's extensive engineering and design efforts undertaken during the recently completed definitive Feasibility Study. In addition, the addenda addressed the development of the gas pipeline to support the energy needs of the operation.

Orocobre's CEO, Richard Seville, said, "Whilst we must still complete the secondary approvals process according to the Provincial Decree announced on 4^th March, we are gratified with the very strong support of the local communities in this UGAMP approval, and see this approval as a continuation of the development of positive relations with the Jujuy government and other stakeholders. We remain confident that our work and the support we are generating at the local level will lead to a timely final approval to build our lithium carbonate project."
