Sale of Salinas Grandes Exploration Assets

Pursuant to the Orocobre-LSC Agreement, LSC will acquire mining properties located in Salinas Grandes in Salta and Jujuy provinces, Argentina ("Salinas Grandes Tenements"), which are held by the Orocobre subsidiary South American Salars S.A.

As consideration for the sale of the Salinas Grandes Tenements, LSC will:

1. Pay to Orocobre US$7 million, with US$4 million payable at closing and a further US$3 million payable by way of 3 annual tranches of US$1 million;
2. Transfer to Orocobre three properties located at Olaroz ("Olaroz Tenements") adjacent to current project properties covering approximately 3,821 hectares, thus strengthening Orocobre's position at its flagship  project; and
3. Grant to Orocobre a 2% royalty on the brine concentrate produced from Salinas Grandes Tenements, calculated on the same basis as the royalties paid by Sales de Jujuy at the Olaroz Lithium Facility to the Jujuy Provincial Government.

Completion of the transaction is anticipated within 30 days.

Managing Director Richard Seville commented, "Following the announcement of the close of the Advantage Lithium agreement yesterday, we are pleased to advise of this transaction with LSC. The deal both improves our cash position and increases our land holding and exploration potential in the Olaroz basin."

About Orocobre Limited
Orocobre Ltd. is listed on the Australian Securities Exchange and Toronto Stock Exchange (ASX:ORE) (TSX:ORL), and is building a substantial Argentinian-based industrial chemicals and minerals company through the construction and operation of its portfolio of lithium, potash and boron projects and facilities in the Puna region of northern Argentina. The Company has built, in partnership with Toyota Tsusho Corporation and JEMSE, the first large-scale, greenfield brine based lithium project in approximately 20 years at the Salar de Olaroz with planned production of 17,500 tonnes per annum of low-cost lithium carbonate.

The Olaroz Lithium Facility has a low environmental footprint because of the following aspects of the process:

• The process is designed to have a high processing recovery of lithium. With its low unit costs, the process will result in low cut-off grades, which will maximise resource recovery.
• The process route is designed with a zero liquid discharge design. All waste products are stored in permanent impoundments (the lined evaporation ponds). At the end of the project life the ponds will be capped and returned to a similar profile following soil placement and planting of original vegetation types.
• Brine is extracted from wells with minimum impact on freshwater resources outside the salar. Because the lithium is in sedimentary aquifers with relatively low permeability, drawdowns are limited to the salar itself. This is different from halite hosted deposits such as Salar de Atacama, Salar de Hombre Muerto and Salar de Rincon where the halite bodies have very high near surface permeability and the drawdown cones can impact on water resources around the Salar affecting the local environment.
• Energy used to concentrate the lithium in the brine is solar energy. The carbon footprint is lower than other processes.
• The technology developed has a very low maximum fresh water consumption of <20 l/s, which is low by industry standards.
• Sales de Jujuy S.A. is also committed to the ten principles of the sustainable development framework as developed by The International Council on Mining and Metals. The company has an active and well-funded "Shared Value" program aimed at the long term development of the local people.

The Company continues to follow the community and shared value policy to successfully work with suppliers and the employment bureau to focus on the hiring of local people from the communities of Olaroz, Huancar, Puesto Sey, Pastos Chicos, Catua, Susques, Jama, El Toro, Coranzulí, San Juan and Abrapampa. The project implementation is through EPCM (Engineering, Procurement and Construction Management) with a high proportion of local involvement through construction and supply contracts and local employment. The community and shared value policy continues to be a key success factor, training local people under the supervision of high quality experienced professionals.

The Company also wholly-owns Borax Argentina, an important regional borate producer.
