E3 Lithium Outlines Clearwater Project Pre-Feasibility Study and Confirms Lithium Reserves

CALGARY, ALBERTA, June 26, 2024 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3 Lithium” or the “Company,” a leader in Canadian lithium, is pleased to announce the summary of key results from the Pre-Feasibility Study (“PFS”) for its Clearwater Project, located in south-central Alberta. The PFS outlines the Clearwater Project's economic viability, environmental sustainability and long-term operational potential, and reports Canada's first lithium-in-brine proven mineral reserve.

The completion of the PFS incorporates 12 months of engineering and design work and includes the data and learnings from the successful 2023 Direct Lithium Extraction (DLE) Field Pilot Plant, as well as the in-house verification testing. The detailed flow sheet outlines a lithium chloride produced from a DLE system and further purified and concentrated. A two-stage chemical conversion process first produces lithium carbonate and then battery quality lithium hydroxide. Critical to sustainability is implementing practices to minimize environmental impact associated with lithium production.

Highlights of the Pre-feasibility Study:

  • Initial production: 32,250 tonnes per annum Lithium Hydroxide Monohydrate (LHM)
  • 50-year operating life: covers only a portion of the total Bashaw District
  • Reserves: 1.29 million tonnes (Mt) of LHM Proven & Probable lithium mineral reserve (1.13 Mt Lithium Carbonate Equivalent (LCE)) from the total Bashaw District of 18.4 Mt of LHM Measured and Indicated mineral resource (16.2 Mt LCE) located in the Leduc Reservoir
  • Strong Project Economics: After-tax NPV $3.72 Billion with a 24.6% IRR at an 8% discount rate (pre-tax NPV8 of $5.18 Billion with a 29.2% IRR) using Benchmark Mineral Intelligence’s (BMI) LHM price forecast
  • Initial Capital Expenditure (CAPEX): $2.47 Billion includes water recycling and contingency
  • Initial Operating Costs (OPEX): $6,200 per tonne LHM provide for a long life and robust project fundamentals
  • Sustainably produced lithium: Process water for the operation will be sourced from recycling and make-up water from waste brine stream, smaller surface footprint relative to conventional lithium production4 with potential plant emissions of 1.9 tonnes CO2e/tonne LHM.

Clearwater Project’s initial production and nameplate capacity is projected to be 32,250 tonnes of lithium hydroxide per year. The Clearwater has a projected production life of 50 years. Over this time, the lithium grade declines over the 50-year period as mixing occurs within the reservoir drainage pattern. This projection is based on a thorough analysis that informed the creation of a detailed reservoir development plan. Production values were determined based on comprehensive reservoir data, to ensure a solid foundation for future operations.

The mineral reserve estimate uses an average lithium price of $31,344 per tonne LHM, and uses negative cash flow as the economic cut-off, which was not realized within the 50-year production life of the project. The total reserve volumes account for 38% of the mineral resource volume within the project area. Capital cost estimates used industry standard estimating practices for a Class 4 estimate. Operating cost estimates were compiled using vendor and engineering data.

The Lithium Production Process

Extraction Of Lithium Brines

The Leduc Reservoir is a well understood ancient reef complex that has exceptional flow rates and deliverability due to favourable rock properties and pressure. A geologic model and subsequent reservoir production model were completed to provide estimates on the brine volume, lithium concentration and producible brine across the Bashaw District. These models were further used to develop the production plan that provided the wells, layout and volumes to be delivered to the Central Process Facility (CPF).

The reservoir drainage model is based on a standard “5-Spot” well network pattern. A total of 38 well pads would produce the required lithium enriched brine: 19 well pads with 4 producing wells and 1 injection well; and 19 well pads with 1 producer and 4 injection wells. The drainage area will have a total of 93 lithium brine producing wells and 93 wells reinjecting the lithium depleted brine. Over time, lithium grade would decline as reinjection brine reaches the production well. Workovers are planned to optimize recovery factor by modifying the well completions. This results in a decline in the production of lithium hydroxide over the 50-year life of the project from 32,250 tonnes LHM per year initially to an average volume of 25,850 tonnes LHM per year.

Brine Production Network: The 38 well pads will be connected via a series of local pipelines to the CPF. These pipelines are underground, similar to oil and gas pipeline networks in Alberta.

Pretreatment: The pretreatment process for brine from the Clearwater area will involve receiving the brine at 70°C and 800 kPa. The water/gas mixture is depressurized to release about 80% of dissolved gas, mainly H₂S. The majority of the remaining gas is captured in a Vapour Recovery Unit in the holding tank. The entrained gases are collected from the brine and re-injected into another reservoir that has no economic value. The brine’s low total suspended solids are expected to be less than 350 mg/L, which would eliminate the need for filtration before DLE.

Direct Lithium Extraction: Lithium chloride would be extracted from degassed brine through a DLE process using an aluminate-based sorbent in a continuous separation process. This process involves columns cycling across operating modes, controlled by dedicated valves.

The process produces no waste streams and requires no chemical treatment within the DLE process.

Purification and Volume Reduction: The Lithium chloride stream from DLE would then undergo purification and concentration to remove contaminants, reduce volume, and recover water for reuse; this involves filtration, reverse osmosis, nanofiltration, and conventional ion exchange processes. The last step of water reduction involves evaporating with a Mechanical Vapor Recompression (MVR) unit, an energy efficient method. The system deploys a “Zero Liquid Discharge” philosophy that recycles all available received water from the various process steps back into an evaporator to produce purified water for use in the Desorption step of the DLE system.

Conversion to Lithium Compounds: The purified lithium chloride would then be converted into lithium carbonate using a chemical precipitation process. The slurry of lithium carbonate is then converted using a similar process into lithium hydroxide. The final lithium hydroxide stream is crystalized into a salt that can be sold directly into the battery cathode manufacturing process.

The only industrial waste that leaves the CPF is calcium carbonate generated during the production of lithium hydroxide. This product is used in cement and could have a market in Alberta or elsewhere. While the PFS has assumed this would be disposed of, there is potential this calcium carbonate can be sold, thereby adding a secondary revenue stream and eliminating all external waste.

Overall, the processing plant is expected to operate at a lithium recovery of 90.4% and an on-time factor of 92%.

Lithium Packaging: The dried lithium hydroxide will be screened and transferred to storage silos through a CO2-free system, packaged in bulk bags via automated stations, and then conveyed to the loading station for storage and transportation.

Capital Costs

The upfront capital costs of the Clearwater Project assume an initial production and nameplate capacity of 32,250 tonnes LHM per year are $2.47 B and are inclusive of the wells, pipelines, processing facility and include 10% contingency on the wells and pipelines and 20% contingency on the plant infrastructure. It does not include the capital for the power generation of carbon sequestration, which has been planned to be built by a 3rd party power provider locally in Alberta where the costs are incorporated into the operating costs for the price of power.

The Clearwater Project will be strategically located within an approximate 10km radius of essential infrastructure, including power and roads, to minimize the expenses related to infrastructure development. Extended infrastructure, such as railway and natural gas, are within approximately 25km of the site. The project is within 2km of a major highway which ensures year-round access and convenient equipment delivery while providing local stimulus and access for staff from nearby towns and cities and eliminating the need for remote camps.


E3 Lithium is committed to environmental sustainability and is developing processes that aim to make the Clearwater Project as sustainable as possible, ensuring the plant operates with minimal environmental impact.

Water Usage: E3 Lithium addresses the consumption of water by deploying advanced filtration and membrane technologies such as Nanofiltration (NF) and Reverse Osmosis (RO) to enhance water recovery in the extraction and refining process. E3 Lithium is also implementing Zero Liquid Discharge (ZLD), which means all process-affected water generated from these systems is recycled back to the process water storage tank. Any additional make-up water required will be sourced from the lithium depleted brine and all of this will be evaporated and condensed using industrial processes to produce purified water, mainly for use in the Desorption process. The ZLD philosophy ensures no liquid waste is released, maximizing water reuse. It also means that once in operation, E3 Lithium should not need to source any water from the environment to make their lithium products.

Land Use: Compared to conventional lithium projects, the Clearwater Project seeks to minimize its environmental footprint by occupying a small portion of land. After construction of the well pads and the pipelines, the majority of the disturbance is reclaimed to its original use immediately. Between the 38 well pads and the CPF, E3 Lithium will use only 10% land relative to a hard rock mine and 4% relative to an evaporative salar4. At the end of the project, the Company will aim for 100% reclamation of the project site. There are no planned tailings.

Carbon Emissions: The project designs include a natural gas fired co-gen power facility that will both generate the required electricity and the heat (in the form of steam) for the CPF. As part of this, E3 Lithium plans to capture the carbon dioxide from the exhaust gas of the power plant and sequester it, supported by recent policy put in place by the Alberta government. If implemented, the carbon emissions from the plant site operations would be an estimated 1.9 tonnes CO2e/tonnes LHM.
