Neo Lithium Files Technical Report with Positive PEA Results on its 3Q Project Showing a Capital Cost reduction of US$98.5M

13.12.2017  |  Marketwired

TORONTO, ON--(Marketwired - December 13, 2017) -

  • CAPEX reduction from US$588.7 million to US$490.2 million through the relocation of evaporation ponds
  • Updated US$1.2 billion after-tax NPV at 8% discount rate
  • Updated IRR of 27.9%
  • Updated payback period of 1 year and 8 months
  • Average production rate of 35,000 tonnes of lithium carbonate per year
  • Results based on simple and proven solar evaporation technology
  • Expected mine life of 20 years with a 3 year ramp up period starting 2021
  • Fully loaded operating cost of US$2,791 per tonne of Lithium Carbonate

Neo Lithium Corp. ("Neo Lithium" or the "Company") (TSX VENTURE: NLC) (OTCQX: NTTHF) announces the filing of a technical report (the "Technical Report") in connection with the release of the results of its preliminary economic assessment ("PEA") for the production of lithium carbonate from its wholly owned Tres Quebradas lithium brine project ("3Q Project") in Catamarca Province, Argentina, titled Preliminary Economic Assessment (PEA) 3Q Project NI 43-101 Technical Report.

The Technical Report was prepared by GHD Chile SA ("GHD"), a leading independent engineering services firm with extensive experience in the design and construction requirements for some of the largest and lowest cost lithium brine processing facilities in Chile and Argentina. The estimation was prepared to a Class 4 level and completed to an accuracy range of ±30%.

Subsequent to the October 30, 2017 news release announcing the PEA (the "News Release"), GHD was able to further optimize the layout of the 3Q Project with the consequent positive impact on the 3Q Project's economics. There were no changes in the assumptions for the processing costs, lithium market and price, process studies and engineering, the lithium resource or the environmental or permitting considerations of the project.

"After we published the initial numbers of the PEA we continued working with GHD to understand the main variables and we identified pond location as a major cost factor" stated Waldo Perez, President and CEO of Neo Lithium Corp. "We were pleased to discover with GHD that a modification in the pond layout provided significant savings in the total CAPEX."

Updated Preliminary Economic Assessment Highlights

Below is a table reconciling the changes to the PEA from those disclosed in the News Release, as required by NI 43-101. The lower capital costs have a larger impact on the IRR and payback period while an important albeit smaller impact on the NPV of the project.

Note: The economic analysis is based upon measured, indicated, and inferred mineral resources only. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The PEA is preliminary in nature and includes inferred mineral resources that are considered too geologically speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the 3Q Project envisioned by the PEA will be realized. The economic analysis of the PEA is based, among others, on the following main assumptions: a) 100% equity financing; b) construction commencing in 2019; c) production ramp up of three years from 2021 to 2023; and d) all capital costs, operating costs and revenues in the economic model are calculated on a constant U.S. dollar basis.

Updated Capital Costs

The total capital costs of the 3Q Project are now estimated to be US$490.2 million, previously being estimated to be US$588.7 million, as noted in the News Release of October 30th. The majority of the savings of US$98.5 million, or 16% of the original total capital costs estimate, was obtained through relocating all evaporation ponds into the salar (previously half the ponds were in the salar and half in the alluvial cone). There were additional costs in regards to infrastructure and others, indirect costs and a larger contingency that are now included in the current capital costs estimate that GHD considered prudent. Building the ponds in the salar is less expensive because it requires less earth movement and there are extra savings in the construction of roads and power generation and distribution.

Process Studies and Engineering

The process begins with the extraction of brine through production wells. From the wells, the brine is pumped into large solar evaporation ponds. The evaporation process in the solar ponds starts with a pre-concentration stage where more than 90% of the sodium chloride from the brine is expected to crystallize out. This pre-concentration stage has an evaporation period of approximately 160 to 180 days, during which the volume of brine is reduced by approximately 95%.

In order to promote the production of lithium carbonate at the lowest possible cost, the solar evaporation process will be designed so that the lithium concentration in the brine reaches values in the range of 2.5%. The pre-concentrated brine is then subjected to chemical treatment with sodium sulfate in order to remove most of the calcium present. The precipitation of gypsum and then post-concentration will bring the lithium concentration in the brine to approximately 6%.

From there, the 6% brine is to be transported to a processing plant to be built in the town of Fiambala, Catamarca (approximately 160 km from the 3Q Project).

The processing plant for producing lithium carbonate includes the final purification of the concentrated lithium brine feeding the lithium carbonate precipitation stage. For this purpose, the conventional process used by lithium carbonate plants in operation has been taken as a reference, which includes the following:

Elimination of the boron content by solvent extraction. First stage where boron-free brine is mixed with mother liquor from the lithium carbonation stage to dilute lithium to 1% and remove Ca (Calcium) and some Mg (Magnesium). Second stage treatment of the boron-free brine with a mixture of slaked lime and soda ash, to remove low residual levels of magnesium. The purified brine, containing 1% lithium dissolved as lithium chloride, is transferred to three reactors in series, where lithium carbonate is precipitated by the addition of sodium carbonate solution (at 28 wt.%). The slurry containing the precipitated product is separated from the mother liquor by filtration and is washed with soft water. Finally, the product is dried, classified and packed.

Additional information with respect to the 3Q Project and the estimated mineral resources thereon can be found in the Company's technical report entitled "Mineral Resource Estimate Technical Report on the Tres Quebradas Lithium Project, Catamarca Province, Argentina". The report is effectively dated as of May 23, 2017. A summary of the resource estimate is highlighted in the table above at two cut off grades: 400 mg/L Li and 520 Mg/L Li. The 20-year mine life is estimated using only measured and indicated resources at the higher cut-off grade of 520 mg/Li and inferred resources are not included for this purpose.

Environmental and Permitting Considerations

The Company is fully permitted for the current work program to feasibility and up to construction. The current focus is on baseline studies and Neo Lithium has completed the analysis for flora, fauna, limnology and microbiology for the summer, fall and winter. Social and archeology studies have also been completed. Soil, air, landscape and paleontology studies are expected to be completed before the end of the year. These environmental studies are required to support the full environmental impact assessment report that is required, along with an economic study, to obtain a mine construction permit. As mentioned in our previously issued news release dated September 6, 2017, this environmental impact assessment report is expected to be completed and delivered to the mining authorities in the first half of 2018 and is expected to be the final permit required before mine construction. An easement agreement has been granted for mine construction and road access to the site.
