We have the very impressive results from Rodinia Lithium PEA on its Brine deposit in Argentina. Stock was beaten very hard during the recent market turmoil, but is recovering very fast from as low as 0.14CAD just few weeks ago. This results are the very good illustration of economic potential for the brine mining in Argentina.
We have been moving down the food chain in our Lithium investment approachstarting with positions in SQM and FMC, then Orocobre, Western Lithium and Lithium One and now we are very pleased with the results for Rodinia Lithium and looking forward to the development of International Lithium (ILC) Mariana brine project in Argentina. ILC is our top pick and we found its recent presentationvery interesting with comparison of market valuations and projects for different lithium developers, including Rodinia Lithium.
Nothing is for certain at this stage - ILC has to confirm the chemistry at Mariana during the upcoming drill program, but we can see the potential of future development. The early stage can provide the very attractive entry opportunity, but you should always consider the risk involved. China is moving fast these days in Electric Space, BYD - Electric Auto and Lithium batteries producer - has announced its plans for strategic cooperation in Argentina last week.
Chinese Shan Shan has a strategic stake in Rodinia Lithium and Ganfeng Lithiumhas just under 10% in International Lithium Corp. TNR Gold with 28% in ILC was up yesterday 36.6% on over 2 mln shares, but it could be related also to other projects of that company. Insiders are buying International Lithium and TNR Gold.
Please, do not forget, that we own stocks we are writing about and have position in these companies. We are not providing any investment advise on this blog and there is no solicitation to buy or sell any particular company here. Always consult with your qualified financial adviser before making any investment decisions.

TORONTO, ONTARIO--(Marketwire - Nov. 7, 2011) - Rodinia Lithium Inc. ("Rodinia" or the "Company") (TSX VENTURE:RM)(OTCQX:RDNAF) is pleased to announce the results of the Preliminary Economic Assessment ("PEA") completed on its 100% owned Salar de Diablillos lithium brine project ("Diablillos" or "Salar") located in Salta Province, Argentina. The PEA outlines an operation producing 15,000 tonnes lithium carbonate ("LC") per year and approximately 51,000 tonnes of KCl ("potash") per year, projecting a 34% internal rate of return ("IRR") pre-tax and a US$561 million pre-tax net present value ("NPV") at an 8% discount rate. The PEA also outlines Rodinia's available option to increase production to 25,000 tonnes LC and 85,000 tonnes potash per year. This increased production scenario generates a much higher pre-tax NPV estimate of US$964 million, along with a pre-tax IRR of 36%. Rodinia continues to advance the technical and processing aspects of the Salar and will commence a feasibility study once the PEA report is finalized.
The PEA was completed by SRK Consulting (U.S.) Inc ("SRK") located in Lakewood, Colorado and is effective as of November 1, 2011. The brine resource model and resource estimate were provided to SRK by Paula Larrondo, Principal Geologist, P.Geo., of AMEC Internacional Ingenieria y Construccion Limitada, Santiago, Chile, Qualified Person ("QP") for the Company's NI 43-101 compliant recoverable lithium brine resource estimate. The complete PEA report will be filed on SEDAR and Rodinia's website within 45 days of this news release.
The table below outlines the key findings of the PEA:
|Preliminary Economic Assessment Highlights (All currency is US$, pre-tax)|
|15,000 tpa LC||25,000 tpa LC|
|NPV at 8% discount rate (pre-tax)||$||561 million||$||964 million|
|Total Initial Capital Costs||$||144 million||$||220 million|
|Operating Costs per tonne LC*||$||1,519||$||1,486|

|Projected commencement of production||2015||2015|
|Years to payback||1.6 years||1.5 years|
|* Averaged using years of full production, discounting ramp up period.|
The PEA is preliminary in nature, includes inferred brine resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the estimates of the PEA will be realized.
William Randall, President & CEO of Rodinia, commented "This PEA is the product of quality work completed on schedule by Rodinia's expert staff and consultants. The PEA demonstrates that Diablillos has the potential to be a low cost producer of high purity, battery-grade, lithium carbonate, potash and boric acid using conventional, environmentally friendly methods to harvest the salts. Due to the favourable geochemistry of the brines, our potash and boric acid production is such that revenue from the sale of these products will result in credits in excess of US$3,500/tonne of LC, more than covering our total anticipated production costs. As long as prices for potash and boric acid remain at today's levels or higher, Diablillos has the potential to remain price competitive down to historic lows for lithium carbonate pricing."
|Financial Sensitivity at Various Discount Rates (US$ millions over 20 years)*|
|Discount rate\Output||10,000 tpa LC||15,000 tpa LC||20,000 tpa LC||25,000 tpa LC|
|* At an average LC price of US$5,500 per tonne. All figures are pre-tax.|
|Financial Sensitivity at Various LC Prices (US$ millions over 20 years)*|
|Price\Output||10,000 tpa LC||15,000 tpa LC||20,000 tpa LC||25,000 tpa LC|
|* At an 8% discount. All figures are pre-tax.|
The Salar has favourable economic potential across a range of discount rates, annual production rates, and long-term LC prices. In all cases the Salar shows robust economics consisting of large NPV values and significant positive cash flows, which position it favourably relative to other PEA reports issued for salars at a similar stage of development in the Puna region of South America.
Will Randall elaborated on the preliminary economics of the Salar, "We are pleased with the results and initial conclusions of this PEA. While the assessment estimates robust economics with first quartile capital and operating costs, we gained considerable insight to further improve on these already favourable numbers. We will look to validate these opportunities during the Feasibility Study phase, which will commence once the PEA report is finalized."
Economic Parameters and Assumptions
The PEA presents a base case operation producing 15,000 tonnes of battery grade lithium carbonate per annum and 25,000 tonnes of battery grade lithium carbonate in the optional production scenario. First production levels of 9,000 tpa LC (15,000 tpa LC for optional production) are expected to be reached after three years of mine construction and pre-production, with full production levels reached two years later. Allowing a further year for the completion of a Feasibility Study, the PEA contemplates initial production by 2015. Management will begin to evaluate methods in which feasibility level engineering and mine construction can be combined to expedite this production timeline. In particular, management will focus on construction of pilot ponds that will subsequently be employed in the commercial production circuit.
Details and Assumptions
Total initial capital expenditures (including contingency) are estimated at US$144 million to produce 15,000 tpa LC and US$220 million to produce 25,000 tpa LC. The initial capital cost estimate excludes closure costs and sustaining capital. Sustaining capital requirements for years 1 to 20 of operation (15,000 tpa LC) were estimated to be approximately US$80 million including wellfield maintenance and replacement.
|Summary of Estimated Initial Capital Costs||15,000 tpa LC
|25,000 tpa LC
|Wells & Ponds|
|Other (wellfield & pond)||11||16|
|LC Crude Plant & Refinery|
|Other (carbonate plant)||9||12|
|Potash Floatation Plant|
Mine construction for a 15,000 tpa LC production facility requires the installation of 23 production wells, approximately 7 square kilometers of evaporation ponds for the production of lithium carbonate, potash and boric acid. At 25,000 tpa LC, the requirements increase to 53 production wells and 11.5 square kilometers. While the wells, evaporation ponds and potash plant are designed to be constructed on the Diablillos property, the current design contemplates constructing the boric acid and lithium carbonate plants off-site at an industrial park in Pocitos. Cost analysis performed on the various options, taking into account capital costs requirements and operating costs, indicated constructing the lithium carbonate and boric acid facilities where access, natural gas, and power are readily available presented considerable cost savings across the board.
A conservative pumping rate of 11 litres per second was employed for this study based on field test work. It is important to note that numerical groundwater flow and solute transport modeling, constraining well drawdown and accounting for dilution impacts on brine chemistry, has demonstrated that higher extraction rates can be achieved from the sand and gravel aquifers predominant at Diablillos. Once further tests are completed on production size wells management expects the estimated capital expenditures required for well construction to be significantly reduced. Pond construction considers an initial unlined pond, where brine is brought to saturation, followed by a series of subsequent lined ponds. There is natural clay occurring on or near Diablillos that will allow for construction of the initial ponds, offering cost savings over lined ponds. Any brine losses experienced in this unlined pond go straight back into the underlying Salar sediments and can be potentially recovered at a later date.
The total average operating costs over 20 years are estimated to be negative at (US$703) per tonne LC once the potash and boric acid credits are applied, based on the following:
|Summary of Estimated Operating Costs||(US$/t LC)||(US$/t KCl)||(US$/t
|Wells & Ponds (total)||408||46||85|
|LC Crude Plant & Refinery (total)||972||-||203|
|Potash Flotation Plant (total)||-||73||-|
|TOTAL LC w/ credits & royalty deductions||(703||)|
Well and pond costs as well as G&A costs were assigned to all three products according to the percentage of revenue generated by each commodity. Potash plant costs were assigned exclusively to potash and LC plant costs were distributed between lithium carbonate and boric acid, as both of these are produced in the same plant complex. By far the largest expense is the cost of reagents, and in particular soda ash and lime, followed by transportation costs.
Consistent with practice in the industry, this PEA has been prepared with an engineering accuracy of +/- 30%. As the project progresses through the feasibility stage, advancement in the detail of engineering will improve the accuracy to approximately +/-15%. The PEA used commodity pricing provided by Rodinia that was assembled from various studies and sources, including industry leading reports and forecasts provided to the Company through its relationship with Forbes & Manhattan Inc., access to industry specialists (boric acid), and generally accepted industry standard pricing based on recently completed studies similar in nature to this PEA. The PEA assumed long-term commodity prices of US$5,500 per tonne LC, US$620 per tonne potash, and US$1,150 per tonne boric acid.
The PEA was prepared in accordance with the guidelines of National Instrument 43-101 by the independent engineering firm SRK Consulting Limited with contributions from AMEC Internacional y Construccion Limitada ("AMEC") of Santiago, Chile, and Mr. Robert Cinq-Mars of North Carolina, USA (whose work experience includes 20 years with FMC Lithium Division as Manager, New Resources and Process Development). SRK is a leading full-service engineering and consulting firm. The final PEA technical report will be filed on SEDAR within 45 days.
Description of Proposed Operation
The proposed operation for Diablillos will largely make use of conventional evaporation based processing, similar to those employed at Silver Peak (Nevada, USA) and Atacama (Chile). The brine is to be pumped from subterranean aquifers by a series of production wells to an initial unlined evaporation pond. The proposed lithium recovery process is a combination of solar evaporation steps, in-field brine treatment, by product potash ("KCl") and boric acid recovery and chemical processing to produce lithium carbonate. The process results in a high lithium recovery of approximately 65%. The process contemplates a series of six ponds from largest to smallest, where the largest is used to bring brine to saturation and is designed to be unlined reducing the capital cost of pond construction. Sylvinite is to be harvested from the third pond, which is proposed to be subsequently upgraded through a conventional floatation process to muriate of potash. Brine extracted from the final pond will have a concentration of approximately 12% lithium chloride and will be transported to the treatment facility in Pocitos, where boric acid and lithium carbonate are produced. For further details please refer to the press release dated October 11, 2011.
Groundwater and Solute Transport Modeling
SRK evaluated potential brine extraction for Diablillos to produce lithium carbonate, potash and boric acid. This modeling was based on the resource estimate conducted previously by AMEC (please refer to the press release dated April 11, 2011), and on work completed more recently by Rodinia and SRK; in particular the completion of pumping tests and additional drilling. The work was completed based on the development of 3-D numerical groundwater and solute transport models and included the assessment of:
- The number of extraction wells needed to meet production targets, their locations, total pumping rates and the subsequent drawdown in surrounding areas
- Expected changes in lithium, potassium and boron concentrations within the extracted brine over time given possible surface water dilution and dilution from surrounding areas containing lower concentrations of these components
SRK completed the numerical modeling using MODFLOW-2005 (groundwater flow) and MT3DMS (solute transport) finite-difference codes that are supported by Visual MODFLOW software (SWS, 2010).
