LEXI Announces Successful Results of Level One Assessment for Accelerated Lithium Processing
TORONTO, Sept. 19, 2018 - Lithium Energi Exploration Inc. (TSXV:LEXI) (“LEXI” or the “Company”) is pleased to announce that, as part of the ongoing engineering work now underway with IBC Advanced Technologies, Inc. (“IBC”), IBC has completed a Level One Assessment (“LOA”) on a sample brine provided by LEXI and is rapidly progressing in conducting successful bench trials for separating and purifying lithium (Li) ions – with a sufficient selectivity factor to produce 99%+ pure Li – utilizing IBC’s proprietary, selective metals separation technology, known as Molecular Recognition Technology (“MRT”). IBC’s work has focused on two of its proprietary SuperLig® resin products for the selective separation and recovery of pure Li. The SuperLig® resins are manufactured exclusively by IBC and are applicable to processing sample brines from the Lithium Triangle. The two SuperLig® resins will allow for effective Li ion extraction from a wide range of brine solutions in which the lithium ions are dissolved. Ultimate selection of the final process conditions using the SuperLig® materials are based on the chemical constituents in the solution and the desired final Li compound to be synthesized for end users.
LEXI’s CEO, Steven Howard, praised IBC’s accomplishments, noting, “The superb chemical engineering team at IBC has spent three decades designing and implementing MRT at commercial scale for a wide variety of other metals, so we expected that validating MRT for lithium selectivity would be a ‘correlated adaptation’, not a start-up science project. This Level One Assessment marks a meaningful milestone in the engineering development for our planned lithium processing plant. The results could not be more timely, since LEXI recently announced its completion of geophysical field studies covering over 36,500 hectares in our northern claim cluster in the Antofalla Salar. Those geophysical results have yielded optimal locations for test wells as soon as circumstances allow. We continue to believe that IBC’s engineering will be completed around the same time that LEXI achieves its first resource estimates.”
IBC’s tasks for the LOA included an evaluation of the brine composition, development of an initial flow sheet, assessment of the preliminary process design and throughput calculations, and determination of the most suitable SuperLig® products and IBC processes for LEXI’s prospective lithium processing plant to extract, separate, recover, refine and purify Li from the evaluated brine. The work involved a thorough review of IBC’s proprietary database of SuperLig® selectivities, the thermodynamic and kinetic properties of IBC’s products and processes, and evaluation of engineering metrics. LEXI provided IBC with a candidate brine representative of actual production brine from one or more salars at or near LEXI’s properties. As the composition of brines may vary across LEXI’s properties, additional comparative work is expected to be undertaken.
From the LOA results, IBC has concluded that the two SuperLig® resins each have the selectivity profiles required, as well as the requisite binding strength and kinetics, to allow for highly efficient Li sequestration from the sample brines provided by LEXI. The LOA portends that these SuperLig® resins will enable Li ion extraction with (1) a Li purity factor of 99+%, (2) a single pass recovery rate of 99+% of the dissolved Li present in the brine, and (3) the minimal usage of weak acid for elution (i.e. releasing the Li ions) into the pregnant eluent at a Li concentration of 10+ grams/liter, allowing for efficient synthesis to produce lithium carbonate or lithium hydroxide. The LOA further validates that suitable flow rates are achievable with relatively low volumes in the wash and elution steps and that energy requirements for operating the system will be chiefly limited to the fluids mixing in tanks, feedstock pumping, wash phases, elution inputs through the columns, and transport to other destinations in the plant, thus yielding very low overall energy requirements. Further substantiated in the LOA, the freezing point depression of the brine should allow for production and processing in severe winter climes with only wash and elution feeds likely requiring some minimal protection to counter sub-zero conditions.
Completion of the LOA has allowed the IBC team to move rapidly into the “Test Work” regime, which is the second of three phases in the testing and engineering services being performed by IBC. The Test Work phase involves lab analysis to validate LOA conclusions. It will enable optimization of brine treatment for Li separation by implementing flow/separation tests, as brine is passed through actual columns containing the chosen SuperLig® resins. Loading and eluting cycles will yield critical kinetic and thermodynamic data, including separation coefficients and process efficiencies. The Test Work phase will also yield detailed flowsheet designs describing each unit operation, its sequential placement relative to other plant operations, its respective inputs and outputs, and the key engineering metrics, including materials of construction, flowrates, temperatures, pressures, and chemical compositions.
IBC’s President, Steven Izatt, stated, “We are excited about the positive conclusions noted in our Level One Assessment, especially following LEXI’s recent announcement of positive geophysical results at the Antofalla Salar. As an integral partner with LEXI, IBC is committed to providing LEXI with a solid technical basis for direct recovery of lithium from brine and production of pure lithium products designed to meet end-user needs using green chemistry and green engineering SuperLig® Molecular Recognition Technology. This successful Level One Assessment is an important milestone that demonstrates achievability of that goal.”
In the final phase of the testing and engineering work, IBC will deliver the basic engineering including process flow and process block drawings, equipment specifications, tank, pump, and column sizes, feed preparation, Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), general arrangement block diagrams, sequential step descriptions for all input/output changes, overall plant valve diagram, overall plant valve/pump on-off valve diagrams for each sequence step, and preparation of the operating manual.
MRT has been proven as one of the most advanced and environmentally friendly refining technologies in the world for selectively separating metals at very high purities and single pass recovery rates to meet demanding customer specifications. With IBC’s collaboration, LEXI has conceived an MRT plant that will be “unit-driven” (i.e. engineering will be designed for a scalable, modular plant).
Under this agreement with IBC, LEXI has the exclusive right of first refusal to obtain site license(s) to use MRT for the separation, recovery, refining and purification of lithium from brine prospects in territories comprising approx. 20,000 square kilometers (7,500 square miles) in two areas of Catamarca Province, specifically including all areas in and around the salars of Antofalla and Hombre Muerto.
All process engineering will be coordinated with LEXI’s expectations and requirements regarding field development, including drilling parameters, well spacing, pumping rates, and other characteristics critical to production from the salar basins in which LEXI’s lithium properties are situated. Although some factors are outside the control of IBC or LEXI, the basic engineering is generally expected to be complete in 12 months or less.
The Company also reports that, as a result of a review by the British Columbia Securities Commission, it has made certain changes to information in the Company’s corporate presentation dated April 2018, previously available on our website, that contained forecasts related to its MRT processing facility plans, including projected capital expenditures, anticipated gross revenues, and expected EBITDA from operations, potentially implying certain economics that were not yet supported by technical work made by the Company or IBC. This disclosure was not in compliance with section 2.3 of National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). As a result, the Company has removed these references from its website, retracts that disclosure and any inferences regarding any economic viability and potential production results in respect of the Company’s plans to utilize MRT for processing lithium.
Our revised presentation is available on our website. The reader is cautioned not to rely on the non-compliant information previously posted on the website or otherwise found in the public domain.
