Salar De Olaroz Lithium-Potash Project

The Olaroz Project is Orocobre's flagship project located in Jujuy province of Argentina.

On 17 October, 2012 the Company announced a major development on the Olaroz Project. Following positive investment decisions by the board of directors of both Orocobre and Toyota Tsusho Corporation Ltd ("TTC"), it was announced that the companies have executed the definitive Shareholders Agreement for a joint venture to develop the Olaroz Project. 

Subsequently, on 6 December, 2012 the Company announced that with joint venture partner Toyota Tsusho Corporation ("TTC"), the companies have executed the loan documentation for the Olaroz project financing. As had been previously announced, the project financing will be provided by Mizuho Corporate Bank Ltd ("Mizuho") with a maximum facility amount of approximately US$192 million as detailed below:

After completion of construction and after satisfying operating performance tests, JOGMEC will provide guarantees for a maximum 82% of the project debt to a maximum of US$158 million.

The overall cost of the debt funding including JOGMEC guarantee is expected to be approximately 4.5% of the drawn amount and will be fixed for the term of the loan at the time of drawing on the debt facility.

The execution of this definitive Joint Venture Agreement and associated financing is the culmination of this two and a half year process, and is a vote of confidence in the project by TTC, Mizuho and JOGMEC. In a business where product quality is of paramount importance it is also an acknowledgment of the quality of the high purity battery grade product produced at the Olaroz Project over the last 18 months. The detailed engineering phase of the Olaroz Project has also been completed, resulting in two noteworthy changes to the scope of the project. First, the design capacity of the operation has been increased to 17,500 tonnes per annum ("tpa") of lithium carbonate from 16,400 tpa provided for in the Feasibility Study. This production improvement is due to an increase in the expected brine grade from 775mg/l in the Feasibility study to 825mg/l following the result of the 3D finite difference modeling under taken since the Feasibility Study (see Company's ASX/TSX Announcement dated 25 January, 2012). With changes to the flow sheet, expected potash recovery has also been increased to approximately 20,000 tpa compared to 10,000 tpa in the Feasibility Study. Potash credits and capital costs are not currently included in the first phase of the project development and are subject to a later investment decision. 

Second, following completion of detailed engineering, and having tendered all material contracts with the exception of the contract for the construction of the lithium carbonate plant, the capital cost estimate has been revised to US$229 million from US$207 million in the Feasibility Study. The revised estimate includes US$22 million of contingency funds and US$16m of expenditure already made. The Olaroz Project Joint Venture is operated through Orocobre's Argentine subsidiary, Sales de Jujuy S.A. ("SDJ SA"). The effective Olaroz Project equity interest will be Orocobre 66.5%, TTC 25.0% and JEMSE 8.5%. (Details of the corporate structure are provided in the Company announcement of 17 October, 2012.

Under the terms of the Joint Venture Agreement, TTC and Orocobre will contribute project equity of US$82.8 million, equating to approximately 30% of maximum project funding if the project financing facility is fully drawn. Further information on the Olaroz Project joint venture agreement and associated financing agreements is available in the Company's announcements of 17 October 2012 and 7 December 2012.

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. Since then, numerous contracts with a total value of US$45m have been executed, or are ready for execution. These include the earth moving contracts for the construction of the 4.2 square kilometres of evaporation pond 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 to this point have been on or under budget.

Since start of official construction, and taking into account the Christmas break, 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 approximately 50% of the evaporation pond area (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 construction of 50% of the access roads on the salar to the bore - field area

Currently 142 construction workers are at site with a peak maximum expected of 400 by mid-2013.

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.

Salar de Cauchari Potassium-Lithium Project (Orocobre 85%)

On 22 October, the Company announced the completion of the maiden resource estimate at its 85% owned Cauchari lithium-potash properties ("Cauchari") in Jujuy Province, Argentina. Cauchari is located approximately 20km south of the Company's flagship Olaroz Project.

From October to December 2011 the company drilled five diamond and one rotary vertical drill holes in the Cauchari properties, followed by chemical analyses of the brine and porosity testing. This work provides the basis of the resource estimate, by independent consulting hydro geologist Murray Brooker, and other conclusions presented in the announcement.

Mr. Brooker has estimated an inferred resource in two adjoining areas of the salar, with a total 230 million cubic metres of brine at average grades of 380 mg/L lithium and 3700 mg/L potassium. This is equivalent to 470,000 tonnes of lithium carbonate and 1.6 million tonnes of potash (potassium chloride) based on 5.32 tonnes of lithium carbonate being equivalent to one tonne of lithium and 1.91 tonnes of potash being equivalent to one tonne of potassium. Details are given in the table below.

To view Table 1, please visit the following link: http://media3.marketwire.com/docs/850306_table_1.pdf.

Due to differences in drill-hole depths the resource has been divided into a northern and a southern resource area. The resource has been estimated using a conservative approach limited by the depth of drilling, with the estimate extending to 170 m depth in the northern area of the properties and 50 m depth in the southern area.

The resource boundaries are constrained by the company's property holdings, drilling results and geophysical survey interpretation. No internal cut-off boundaries have been used because both the Company and Competent Person/Qualified person consider it is inappropriate to apply them in a fluid resource where extraction will cause mixing. No external cut off was defined for the resource, due to the limited drilling and pit sampling completed on the project to date. The property boundaries were used as the western, northern and southern boundaries to the brine resource. Hole CAU006R was excluded from the resource due to a different drilling and sampling methodology and sub 100 mg/l Li composite sample results.

Exploration Target

Based on available geophysics, geology and geochemistry it has been is possible to define an exploration target beneath the resource outlined in Table 1. It must be stressed that an exploration target is not a mineral resource. The potential quantity and grade of the exploration target is conceptual in nature, and there has been insufficient exploration to define a Mineral Resource in the volume where the Exploration Target is outlined. It is uncertain if further exploration drilling will result in the determination of a Mineral Resource in this volume, however available information suggest this is likely.

The contained lithium in the exploration target (combining values for the northern and southern areas - see Table 2) ranges from the Upper Assumption case of 2.6 mt of lithium carbonate and 9.2 mt of potash to the Lower Assumption case of 0.2 mt of lithium carbonate and 0.5 mt of potash.

It must be stressed the exploration target is based on a series of assumptions and future drilling is required to determine the brine grade and formation porosity (Sy) values to establish whether a resource can be defined.

To view Table 2, please visit the following link: http://media3.marketwire.com/docs/850306_table_2.pdf.

The brine body has attractive chemistry, with a low magnesium to lithium ratio (2.8) in the five diamond holes and a high potassium to lithium ratio (10). The sulphate to lithium ratio averages 61 in diamond holes CAU001D-4D, rising to 114 in hole CAU005D in the eastern part of the resource area. Initial evaluation of the brine chemistry suggests high recoveries of lithium could be expected using a process route similar to that at the adjacent Olaroz project.

Considering the similarities and close proximity of the Cauchari and Olaroz projects, there are compelling synergies including the expected use of shared infrastructure and processing plants, and it is likely that any future development of the Cauchari brines would use the Olaroz facilities. Consequently, from this point forward the company considers the Cauchari project and its brine body part of the larger Olaroz project. In the future, resources for Cauchari will be reported as a discrete part of the overall Olaroz project resources.

Further technical information on the Cauchari maiden resource estimate is available in the Company's 22 October, 2012 announcement.

Borax Argentina

Borax Argentina has extensive operations and has a fifty year production history producing borax chemicals, boric acid, "boro-glass" and boron minerals. Production currently comes from three principal mines at Tincalayu, Sijes and Porvenir, concentrators at the first two with 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, 5,139 tonnes of tincal mineralisation was mined, 37,009 tonnes of hydroboracite, ulexite and colemanite mineralisation was mined at Sijes and 25,359 tonnes of ulexite mineralisation was mined at Porvenir during the quarter. 

Approximately 10,007 tonnes of combined products was sold.

During the quarter, work commenced to develop the programmes to convert some of the historical estimates to JORC/NI43-101 compliant resources. The first phase will commence this quarter and be focussed on assessing database quality and re-logging core. During the quarter a number of studies were also initiated to look at operational improvements to reduce unit costs.
