CALGARY, ABNov. 16, 2020 /CNW/ – E3 METALS CORP. (TSXV: ETMC) (FSE: OU7A) (OTC: EEMMF) (the “Company” or “E3 Metals”), an emerging lithium developer and leading lithium extraction technology innovator, today announced the results of its Preliminary Economic Assessment (“PEA”) of its 100% owned Clearwater Lithium Project. The PEA outlines the estimated production of 20,000 tonnes per year of battery-quality lithium hydroxide monohydrate (“lithium hydroxide” or “LHM”) over a 20-year period.  The Company will file the PEA on SEDAR within 45 days.

The PEA was prepared by Scovan Engineering, NORAM Engineering and Constructors, GLJ Ltd. and Fluid Domains, each being specialists in their field of practice specific to the development of this project. More detail on the contractors is available at the end of this news release. All values reported are in USD unless otherwise noted.


  • Pre-tax USD 1.1 Billion NPV at 8% discount rate and IRR of 32%;
  • Total initial CAPEX estimate of USD 602.0 Million inclusive of both direct and indirect capital costs and 79.8 Million in contingency
  • 20-year project-life producing 20,000 tonnes per year of battery-quality LHM. Over the project-life, a total of 400,000 tonnes of LHM is contemplated being produced from the Clearwater Resource, leaving room for expansion across the Clearwater Resource Area and in E3 Metals’ adjacent Exshaw and Rocky Resource Areas; and
  • All-in operating costs of USD 3,656 per tonne LHM, USD 73.2 Million annually, including all direct and indirect costs.

“E3 Metals is very encouraged by the results of this Preliminary Economic Assessment that incorporates a significant amount of data and work completed over the past few years to develop both the processes and technology” commented Chris Doornbos, President and CEO of E3 Metals. “The combination of electrochemically produced lithium hydroxide, targeted process re-cycle streams, and relatively low cost of energy in Alberta provides for a very attractive trade-off between OPEX and CAPEX. This provides a robust OPEX capable of withstanding lithium hydroxide price fluctuations. We are very excited to be moving forward with the project development work into 2021 as we progress on the path to a Pre-Feasibility Study.”

The PEA is preliminary cost estimate 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 the Clearwater Project outlined by the PEA will be realized. The economic analysis of the PEA is based on the following main assumptions: a) forecast LHM price of USD 14,079 averaged over the life of the project, b) annual production of 20,000 tonnes per year LHM, c) commerciality of E3’s DLE technology and, d) estimated operating and capital costs for the project based on the most current data available.

Project Development

The Clearwater Project consists of over 250,000 acres located in south-central Alberta, Canada. The development plan prepared for the PEA includes three main process steps designed to deliver 20,000 tonnes of battery-quality lithium hydroxide monohydrate per year.

Brine Production & Pre-Treatment: Based on the large amount of geological data available from oil and gas operations in the Clearwater Resource Area, it is expected that lithium grade is consistent throughout the Clearwater Resource Area and that a series of wells, drilled specifically for the production of brine, would be capable of delivering 3,300 m3/day per well. At an average grade of 74.6 mg/L lithium, the project will move just over 128,000 m3/day of brine, with additional well production capacity in excess of this. As Direct Lithium Extraction (DLE) processing does not evaporate the water contained within the brine, the lithium void brine is returned to the aquifer through a series of injection wells. This re-injection of lithium depleted brine will serve to maintain pressures and brine production rates in the aquifer. The brine production process step also includes pre-treatment for removal of H2S from the brine prior for delivery to the Direct Lithium Extraction (DLE) process.

Direct Lithium Extraction: E3 Metals’ proprietary Direct Lithium Extraction (DLE) process deploys an ion-exchange process that is highly selective for lithium over competing cations in the brine. Results of this technology have been outlined by E3 Metals in previous announcements. This process produces a highly concentrated lithium solution (“Li-IX solution”) with a low level of impurities for delivery to the lithium production process.

Lithium Production: There are several stages included in this process step designed to deliver battery-quality lithium hydroxide. The first step includes further concentration of the Li-IX solution, followed by polishing steps to remove the remaining impurities. The solution is then fed into electrolyzers where a highly pure lithium hydroxide solution is formed. From there, the lithium hydroxide solution is crystalized into lithium hydroxide salts. The crystalized lithium hydroxide is then packaged and transported to a nearby rail network where it can be transported to eastern and western shipping ports for international distribution, or south for sale directly into the American market.

In additional, USD 108.7 Million of sustaining capital is also estimated, with the majority of this cost associated with the replacement of brine production pumps.

Mineral Resource Estimation

The inferred mineral resource estimate for the Clearwater Resource Area has been updated to 410,000 tonnes of elemental lithium, an increase of 14%. Using a conversion factor of 5.323, this equates to 2,200,000 tonnes of lithium carbonate equivalent (LCE). Several factors contributed the updated estimate, including: 1) an expansion of the resource area by 85 km2based on additional permits E3 Metals acquired since the initial resource estimate in 2017; 2) new and repeated sampling within the resource area has resulted in an updated average concentration of 74.6 mg/L Li; and 3) updated well network modeling has outlined the ability for the reservoir to produce a larger amount of lithium from brine than was originally envisioned, increasing the production factor from 50% to 80% in some areas.

The resource is classified as inferred because geological evidence is sufficient to imply but not verify geological, grade or quality continuity. It is reasonably expected that the majority of the Inferred Mineral Resource Estimate could be upgraded to Indicated Mineral Reserves with continued exploration.

Lithium Pricing and Production

A detailed future pricing study for lithium chemicals was not completed for this PEA. The average price used for future sales of battery-quality lithium monohydrate hydroxide was developed by reviewing pricing data generated from reliable sources as reported in publicly disclosed data collected from peer companies. The future average selling price of USD 14,079/tonne lithium hydroxide is consistent with that used for publicly released economic assessments of other lithium projects in the previous 4 months. Future selling prices ranging between USD 12,910/tonne to USD 17,238/tonne were modelled as part of a sensitivity analysis exercise.

The total production of 20,000 tonnes/year lithium hydroxide is based on recovery of lithium from the enriched brines of the Leduc Aquifer in Alberta. It does not take into account the ability for E3 Metals to increase production of brine and subsequent expansion of production facilities to increase total lithium production. Nor does it contemplate the possibility of including brine streams from oil and gas operators in the area (i.e. oilfield produced water), which could potentially be added to the feed brine stream at a small incremental cost to the company.
