International Lithium Files Technical Report with Indicated Resource Estimate of 1.25 Million Tonnes LCE at the Mariana Lithium Brine Project, Argentina
Vancouver, British Columbia (Newsfile Corp. - April 20, 2017) - International Lithium Corp. (TSXV: ILC) (the 'Company' or 'ILC') is pleased to announce, with strategic partner Ganfeng Lithium Co. Ltd., ('GFL') and together the 'Companies', the filing of a technical report that contains a maiden resource estimate for the Mariana lithium brine project (the 'Project') located in Salta, Argentina.
Further to the Company's news release dated March 8, 2017, ILC has filed a technical report for the Mariana lithium brine project containing a maiden resource estimate for the project. ILC requested Geos Mining Minerals Consultants ('Geos') based in Sydney, Australia to prepare an independent lithium brine resource estimate for the Companies' Mariana lithium brine deposit in Argentina, and with Geos consent, ILC prepared a technical report in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (the 'Technical Report').
The Technical Report, entitled 'Technical Report; Mariana Lithium Project, Salar de Llullaillaco, Argentina' and dated April 10, 2017, is now available under the Company's profile at www.SEDAR.com. The effective date for the resource estimate is January 20, 2017, which represents the date of the most recent data that supports the brine estimate in the Technical Report.
Report Highlights - Mariana Lithium Brine Project, Argentina
The following highlights taken from the Technical Report, and set out below, should be considered in the context of the detailed information given there.Indicated resource contains an estimated 1,248,000 tonnes of lithium carbonate equivalent (LCE), previously reported with at a 60% recovery rate to be 747,000 tonnes LCE which is now calculated as 749,000 tonnes of LCE.Inferred resource contains an estimated 618,000 tonnes of LCE.The indicated resource is estimated at 765 billion litres of brine grading 306 mg/L lithium ('Li') and 9,457 mg/L potassium ('K').The inferred resource is estimated at 361 billion litres of brine grading 322 mg/L lithium ('Li') and 10,316 mg/L potassium ('K').Brine resources are tabulated and reported for average specific yield (SY) of 15% and a cut-off value of 230 mg/L Li. Effective date for this resource estimate is January 20, 2017.
The preliminary estimates for lithium brine are in the upper end of the Companies' expectations.
Further Report Details
ILC has completed four drilling campaigns on the Project since 2009: 7 reverse circulation (RC) holes and 16 cored holes. A total of 2,880 m were drilled on the Project during the last 10 months. A final campaign hole, MA16-24, was in-process as at the effective date of the Technical Report. Geophysical surveys were conducted downhole for the completed drill holes, using an electrical probe. Resistivity and spontaneous potential were measured. As part of a bulk extraction of lithium from brine bulk testwork undertaken in 2015 a pumping well, MA15-09-PW, and 2 monitoring wells, MA15-08-MW, MA15-10-MW, were drilled and constructed. Drill hole MA12-07 was used as a third monitoring well. The drilling and hydrogeological data indicates that the Mariana Project at Salar de Llullaillaco is a brine-bearing sedimentary filled basin complex with unconfined interconnected aquifer to considerable depth of 328m and possibly deeper. Based on the preliminary drill information, eight lithological classes were identified in the drill hole cores, shown in the west, east and southern extents of the basin. The aquifer volume is still open at depth in the majority of the salar since only two drill holes (MA16-23 and MA16-18) potentially intercepted suspected basement Oligocene to Pliocene volcanic lithologies.
Brine deposits are unlike the majority of mineral deposits in that they are fluid. Fluids within a brine deposit can move, and can mix with adjacent fluids when exploitation of a brine deposit begins. Evaluation of such deposits therefore requires special considerations that are not, in general, applied to other style of mineral deposits.
The assessment of brine deposit has been limited to defining mineral resources at different levels of certainty, varying from Indicated Resource to Exploration Target, based on the certainty provided by the data collected during fieldwork. Levels of assessment, as linked to data certainty are listed below, covering those areas that fall within the Project tenements only.
Brine resources are tabulated and reported for average specific yield (SY) of 15% and use a cut-off value of 230 mg/L Li in Table 1.
Table 1: Total indicated and total inferred resource estimates.Category Effective Volume M m3 Brine Density g/mL Li mg/L B mg/L K mg/L SO42- mg/L Mg mg/L HCO3- mg/L Li K t LCE#K t Indicated 766 1.218 306 599 9,456 15,530 4,291 529 234 1,248 Inferred 361 1.222 322 642 10,316 15,315 4, 566 535 116 618
The Indicated Resource of 766 Mm3 at a grade of 306 mg/L Li equates to 234Kt of lithium as Li ion. Upon conversion of Li to lithium carbonate (Li2CO3) using a conversion factor of 5.324, gives an equivalent of approximately 1.3 Mt of Li2CO3. However, using a conservative 60% estimated total recovery return from processing gives a conservative estimate of 749 Kt of Li2CO3 equivalent (LCE).
In preparing this resource estimates, Geos considered and applied processes to be appropriate for brine style deposits, using the principles set out in National Instrument 43-101 ('NI 43-101'), Joint Ore Resources Code JORC (2012) for mineral projects, and CIM Best Practice Guidelines for Resource and Reserve Estimation for Lithium Brines.
The Company cautions the reader that no economic studies have been carried out on the Project. Mineral resources are not mineral reserves as defined by the Canadian Institute of Mining and Metallurgy, and the Company cannot guarantee that the resources reported here will be converted to mineral reserves.
The initial brine resource estimate for the Project is based on limited knowledge of the geometry of individual aquifer units between broadly spaced drill holes, and the variation in porosity and brine grade within these aquifers. Specific yield values are based on porosity test results from a restricted sample population and compared with data from analogous salars in the region and technical references. In order to assess the recoverable brine resource with a higher level of confidence, further information on the permeability and flow regime in the aquifer, and watershed basin water balance are necessary.
Conclusions and Recommendations from the Report
The project is moving forward from early stage exploration to advanced exploration. Work on the following tasks is currently underway and was originally scheduled to be completed by the end of 2017:Detailed pump test;Construction of evaporation ponds;Water balance studies;Transportation studies;Environmental baseline and archaeological study; andPreliminary feasibility study.
Updating of the mineral resources estimated in the Technical report is another recommendation which will help to support the preliminary feasibility study. This work will include further exploration to bring the remaining inferred resource to indicated stage, and indicated resource to measured resource.
Kirill Klip, Executive Chairman of ILC stated, 'We are very pleased with the results of the maiden resource estimation at the Mariana lithium potash brine project, together with our strategic partner Ganfeng Lithium. This project is now moving from an early exploration stage to an advanced exploration stage where it will be more easily compared to other lithium brine projects in Argentina. We are looking forward to follow up with Ganfeng Lithium on the recommendations of this report in order to ensure the rapid advancement of the project towards the pilot stage and to conduct further feasibility studies that will investigate the economic viability of the Mariana project.'
