ASX/TSX Announcement: Orocobre Responds to New Argentine Foreign Currency Transfer Regulations

BRISBANE, AUSTRALIA--(Marketwire - Oct. 27, 2011) - Orocobre Limited (TSX:ORL)(ASX:ORE), ("Orocobre" or the "Company") wishes to inform shareholders of the changes to foreign currency transfer regulations in Argentina.

The national Government of Argentina has announced via decree that export revenues from mining projects must be repatriated to Argentina and converted to Argentine currency prior to being distributed either locally or overseas. The payment for goods and supplies from overseas and the distribution of dividends will then require the Argentine currency to be converted to the foreign currency of the transmittal. This overturns the previous benefits provided by Argentina to oil and mining companies, in 2002 and 2003-04 respectively, that exempted them from the currency repatriation laws that apply to all other primary producers in the country.

A preliminary analysis of the decree by our legal counsel in Argentina indicates that it does not change the current regulations that allow, subject to the Argentinean central bank rules, the unlimited purchase and transfer of foreign currency to offshore destinations in consideration the purchase of equipment or supplies, debt repayment or dividend payments.

Orocobre will continue to investigate through its Argentine legal counsel and advisors any other implications on the financial and operational aspects of the Company that may arise from the new regulations.

In the meantime, the Company continues to advance the Olaroz project with the detailed engineering and is also undertaking exploration programs at Cauchari and Salinas Grandes Projects.
