Orocobre Limited Olaroz Lithium Facility Operations Update

Brisbane, Australia (ABN Newswire) - Orocobre Ltd. (ASX:ORE) (TSE:ORL) (Orocobre or the Company) wishes to advise on progress at the Olaroz Lithium Facility.


Highlights:

- Production ramp up continues with lithium carbonate production of 93 tonnes in July and 143 tonnes in August

- Production planned for September is 250 tonnes

- Monthly nameplate production targeted for December 2015

- Work continuing on removing bottlenecks and improving operating practice

- FMC Corporation (NYSE:FMC) announces a 15% price increase for lithium products effective 1st October 2015


Production update and forecast

Over the past months, priority has been given to the identification and implementation of long term solutions for operational challenges, debottlenecking and equipment rectifications rather than maximizing daily production. This approach has necessitated numerous periods of testwork and equipment trials with consequent reduced flowrates through the Facility, which in turn has had a direct impact on the production performance of the plant versus forecast.

Production ramp up at the Olaroz Lithium Facility has continued to improve, with 93 tonnes produced in July, 143 tonnes produced in August and 250 tonnes scheduled to be produced in September. Nameplate production run rate is planned to be achieved in December 2015.

The Olaroz Lithium Facility will reach breakeven point on an operating cost basis (net of taxes paid or reimbursed), when production reaches approximately 650 tonnes per month, subject to variability in sales price. This level of production is expected to be achieved in October 2015.


De-bottlenecking progress

Significant progress has been made in the de-bottlenecking program.

- Heat Exchangers: Elevated temperatures in the return solutions had made the absorption part of the purification circuit approximately 10 degrees higher than target, thus limiting lithium carbonate dissolution. Design engineering work for the required cooling system in the purification circuit has been completed and consequent modifications to the plant will be completed in the week commencing 21 September. Modifications to the circuit were effected using existing heat exchangers rather than using cooling towers as originally considered.

- Polishing Filters and Centrifuges: Work undertaken to improve the operational performance of the polishing filters in the primary circuit, which remove calcium and magnesium precipitates, did not increase the filtering capacity to a sufficient level. Flow rates were being further reduced by higher crystal loads caused by colder weather restricting flow rates through the plant. A solution to this capacity constraint was found with the successful trialing of a centrifuge sourced from Borax Argentina's Tincalyu plant, which has the capacity to separate lithium solids from liquids by its rapid spinning and use of centrifugal force without clogging. This centrifuge has a capacity of 40m3/hr and was quickly installed on an existing platform. To reach the nameplate flowrate a second centrifuge, which is already on site, will be installed in October.

The installation of both centrifuges will allow the flow rates through the Facility to reach nameplate capacity and require far less maintenance than the previous filter solution.

The Outotec polishing filters are being reassigned to provide additional filtering capacity in the recovery of lithium carbonate solids remaining in the circuit prior to their discharge from the plant, thus improving overall recovery rates for the Facility. This modification to the plant will also be completed the week commencing 21 September.

- Boiler Increase: Engineering studies undertaken during the design of the cooling requirements in the absorption part of the purification circuit discussed above have identified a new heat deficiency on the crystallizer end of the circuit. Additional boiler capacity will be added during November to address this deficiency. The increase in boiler capacity will permit the crystallizers to meet full capacity.

The centrifuges and additional boiler will cost approximately US$1m.

The progress in debottlenecking through the quarter to date has been very pleasing and the Company is now confident that all significant issues have been identified with solutions to the problem either complete or in the process of being implemented.


Reaching Nameplate Production

The following key factors will enable the planned ramp-up in the production profile to be achieved:

- Completion of debottlenecking activities which will allow the Facility to operate at its design flow rates.

- Brine profile - as disclosed in the June quarterly report it is expected that by October 2015 there will be sufficient quantities of concentrated brine to supply the Facility at full capacity. In particular, during October, the brine feeding the plant is forecast to reach the design grade of approximately 0.7%, enhanced by increasing evaporation rates. Recoveries of lithium carbonate from the plant are directly proportional to the feed grade. Consequently, lithium recovery in the plant will improve as grades rise to the design specification.

- Ongoing operational improvements being achieved from a workforce becoming increasingly experienced and knowledgeable in plant processes.

Taking into account the aforementioned drivers, ramp up will continue to accelerate to reach nameplate run rate in December.


Financing

The Joint Venture SDJ SA paid US$7.0m in September 2015 as the first principal and interest payment on the US$191.9m debt facility. The next principal and interest payment obligation for the joint venture company SDJ SA is approximately US$13.5m, due in March 2016.


Sales Orders

Commercial shipments of lithium carbonate have continued to be dispatched from the Olaroz Lithium Facility to Europe, Japan and the USA. As previously advised samples have been sent to 19 battery and 13 industrial sector customers as the final stage of product qualification with positive initial responses already received from a number of these customers. All forecast production for CY2015 has now been fully committed and customers are awaiting delivery.

Given the very tight market conditions the main customer concern remains the long term security of quality supply. The Olaroz Lithium Facility should substantially fulfil this need.

Market Conditions

FMC Corporation, one of the world's largest producers of lithium products, has announced a 15% price increase effective from 1 October 2015, noting that "continued market growth is outpacing current industry supply capabilities for most of our product lines". The price increase will apply to lithium carbonate, lithium chloride, lithium hydroxide and all other lithium products with the exception of specialty organics. FMC attributed the price hikes to demand-supply discrepancies and a desire to reinvest in facilities.

Lithium market conditions continue to tighten. Supply side constraints coupled with strong market demand is resulting in upward pressure on market prices for lithium carbonate. Prices in recent times have been steadily increasing over US$6,000/tonne. The traditional annual fixed price contracts are now being replaced by shorter bi-annual, quarterly and even monthly (load by load) pricing arrangements.

The market growth rate projected by independent consultants is ~10% year on year for at least the next few years (Roskill forecast to 2017, IHS forecast to 2025). These market growth rate projections were published prior to announcements by Tesla, Foxconn, Samsung LG and BYD for new and expanded battery factories.

There is increasing momentum in the electric vehicle (EV) sector with increasing participation by mainstream brands, a growing focus on grid power storage at a commercial and residential scale, improving viability of solar-lithium battery systems and continued growth in the demand for portable electronic devices, underpinned by the growth in emerging markets.


Managing Director Comments

Managing Director, Richard Seville, said, "We remain positive about our progress at the Olaroz Lithium Facility despite falling short of our previously announced production forecast. We have continued to make rapid advances in removing bottlenecks and we improve our "know how" and operating practices on a daily basis. In particular, we are very pleased with the solutions we found to excess crystal loading on the polishing filters by finding a better technology using centrifuges and releasing the existing filters to recover additional lithium carbonate from tailings streams.

We will continue to work hard to deliver the outcomes necessary to reach nameplate capacity by year's end and finish establishing Olaroz as a premier production site of high quality product for the battery and industrial sectors."
