Salar De Olaroz Lithium-Potash Project

The Olaroz Project is Orocobre's flagship project located in Jujuy province of Argentina. Together with partners, Toyota Tsusho Corporation ("TTC") and Jujuy Energia y Mineria Sociedad del Estado ("JEMSE"), Orocobre is building the first large scale "green fields" lithium brine project in approximately 20 years. The project has a budgeted construction cost of US$229m and has a design capacity of 17,500tpa of battery grade lithium carbonate. Financing has been completed with the partners contributing US$82.8m. A low cost debt facility for up to US$192m has been arranged with Mizuho Corporate Bank.

The Olaroz Project joint venture is operated through Argentine subsidiary, Sales de Jujuy S.A. ('SDJ SA"). The effective Olaroz Project equity interest is Orocobre 66.5%, TTC 25.0% and JEMSE 8.5%.

Salar de Olaroz Construction Update

Construction of the Olaroz lithium project officially began on 21 November, 2012. Progress has been swift due in a large part to the preparation and planning that took place in the preceding year. Sinclair Knight Merz, with the assistance of INFA, a well-respected Argentine engineering group, completed detailed engineering for all areas of the operation, including brine extraction, transport and evaporation, the lithium carbonate plant and key areas of the re-purification and micronizing circuits. The procurement process was also well advanced with all main suppliers identified and with many construction and supply contracts at an advanced stage of negotiation or ready for awarding by the construction commencement date.

In addition, prior to official construction start, various aspects of site preparation had been advanced, including the drilling of fresh water bores and pumping station and the time consuming removal of scrubby vegetation, "tolar", from the area of the evaporation ponds prior to earth moving. This includes the earth moving contracts for the construction of the 4.2 square kilometres of evaporation ponds and road construction for the bore field access road across the salt lake (which will allow production bores to be drilled), the drilling contract for sixteen 200m production bores, purchase of 37km of pipeline for gas supply, and the establishment of the construction camp, fuel and water supply. All major contracts awarded and executed to this point have been on or under budget.

Since the start of official construction significant progress has been made on site as follows:

• The establishment of the construction camp at Olaroz, and the renting of supplementary accommodation at the nearby town of Susques for first stage construction crews
• Mobilization of earth moving equipment and commencement of works
• The clearing of tolar over the majority of the evaporation pond area (4.2 sq km) and the commencement of earth works for evaporation pond construction.
• Establishment of a long term water supply to be used both for both domestic and construction purposes
• Establishment of fuel supply/storage and telecommunications
• The continuing construction of the access roads on the salar to the bore field area.

The following tasks have been completed to date:

• Earthworks and platform construction for the camp, customs yard, lime plant and effluent treatment plant
• Fencing for the customs yard
• Vegetation removal at 5A and 5B evaporation ponds
• Aquaduct pipe manufacturing
• Dining area and labour bedroom modules
• Sewage treatment plant construction
• Lime plant conveyor construction
• Concrete supplier mobilization
• Concrete Plant installation
• Contractors camp relocation
• Sewage treatment plant construction

The following tasks are currently in progress:

• Manufacturing of the worker's accommodation and dining pavilions
• Manufacturing of the lime plant conveyor belt
• Manufacturing of the ball mill for the lime plant
• Installation of the camp effluent plant
• Erection of the water pumping station equipment
• Construction of evaporation ponds
• Road and drilling platform construction on the salar
• Manufacturing of lime plant silo and tanks
• Equipment and mechanical installation at pumping station and water intake
• Tola Vegetation Removal and recycling at the pond area
• Lime plant silos, tanks and other facilities construction
• Road and platform construction on the salar
• Evaporation ponds construction
• Production wells drilling
• Grounding and concrete foundations for Lime Plant
• Aqueduct construction
• Gas Pipeline construction
• Brine pipeline construction
• Protection channels construction
• Camp modules installation
• Warehouse Area fence construction

Approximately $87m of the US$229m capital budget has been committed or spent and all major contracts awarded to this point remain on, or under, budget.

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 unique community and shared value policy continues as a key success factor, training local people with supervision by high quality experienced professionals.

Celebration of the Official Opening of Olaroz Construction

A large function involving dignitaries, government, company staff, ten local community representatives and members of the business community was held on Thursday 14 March at the Salar de Olaroz to celebrate the official opening of the Olaroz project construction. Approximately 500 people attended.

The ceremony was attended by dignitaries Amado Bodou, Vice-President of Argentina; Eduardo Fellner, Governor of the Province of Jujuy; Hector Luzco, Susques Municipal Commissioner; Misashi Mizukami, Japan's Ambassador to Argentina and company representatives, James Calaway, Chairman; Richard Seville, Managing Director; Federico Nicholson, Director; Jose De Castro Alem, Group General Manager.

Borax Argentina

Borax Argentina has extensive operations and has a fifty year production history producing borax chemicals, boric acid and boron minerals. Production currently comes from three principal mines at Tincalayu, Sijes and Porvenir with concentrators at the first two locations and a chemicals plant at Campo Quijano producing refined products.

There are historical estimates on the mineralisation at these mines and at two undeveloped deposits. These form the basis for developing plans for the business.

Operations

The Borax Argentina operation performed as planned and expected over the quarter. At Tincalayu, 6,615 tonnes of tincal mineralisation was mined and 14,430 tonnes of hydroboracite, ulexite and colemanite mineralisation was mined at Sijes. Porvenir has been in a planned shut down this quarter.

Approximately 9,182 tonnes of combined products were sold, in line with budget although prices received were lower than expected due to generally softer market conditions.

During the quarter, work progressed in the programmes to convert some of the historical estimates to JORC compliant resources. Also during the quarter a number of projects were progressed to improve operations and reduce unit costs.

New developments - Borax Argentina Develops Nuclear Grade Boric Acid

On 20 March the Company announced the development of a new chemical product by Borax Argentina.

In early March Borax Argentina SA made the first shipment of Boric Acid HPN (High Purity Nuclear) Grade to a customer in Brazil. Boric Acid HPN is a new refined chemical product developed by Borax Argentina over the last six months with characteristics of high purity (greater than 99.9%) and low levels of key impurities such as iron, sodium, chlorine, sulphur. Heavy metal levels are less than one part per million. The high boric acid content and low impurity levels makes the product suitable for use in nuclear power plants. Boric acid is used in nuclear power plants to slow down the rate at which fission is occurring.

The development of this new product reinforces the inherent flexibility in the Borax Argentina operation and highlights the ability of the business to produce new specialist high specification products for high value niche markets. Boric Acid HPN will form an integral part of the product portfolio as Borax Argentina becomes more geographically diverse by growing its presence in key international markets.

This follows on from the recent development of a high grade hydroboracite product for the agriculture market.
