E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3 Lithium” or the “Company,” Alberta’s leading lithium developer and extraction technology innovator, today outlined the Key Performance Indicators (KPIs) for its Direct Lithium Extraction (DLE) field pilot plant, which remains on track to commence operations in Q3 2023.

E3 Lithium’s field pilot plant will be located east of Olds, Alberta, at the first well completed during its 2022 inaugural drill program. That program, which included sampling from three wells, confirmed reservoir characteristics and average lithium concentrations of 75 mg/L in the Leduc Reservoir.

The field pilot is designed to test and validate DLE technology in real-world operating conditions to develop the design and cost estimates for E3 Lithium’s first commercial facility. Outlined below are a set of parameters, or KPIs, for the field pilot plant.

Pilot KPIs: E3 Lithium will measure the success of the field pilot plant against the KPIs below.

Success Criteria

Key Performance Indicator (KPI)

Description

Lithium recovery

≥ 80%

Mass of lithium recovered from the mass of lithium in the feed

Lithium grade in the lithium product stream

≥ 25%

Concentration of lithium relative to other impurities (Na+K+Ca+Mg+Mn+Sr+B)

≥ 600 mg/L

Concentration of lithium in the lithium product stream

Flow rate ratio

≥ 3

Brine flow rate divided by the system volumetric capacity

Lithium Recovery: The basis for including ≥ 80% lithium recovery is that it enables E3 Lithium to maximize the value of each unit of brine brought to surface.

Lithium Concentrate Quality: The quality of the product stream, or concentrate, containing lithium ≥ 600 mg/L with low impurities (≥ than 25% lithium in the product stream) outlines a high lithium to impurity ratio that enables simplified and conventional downstream refining into battery quality lithium hydroxide.

Flow Rate: The flow rate ratio is a measure of the rate at which the lithium can be extracted from the brine within a fixed capacity. The higher the ratio, the smaller the DLE commercial plant required, which is a proxy for the capital costs of this system.

DLE Technology

Along with testing its DLE technology to demonstrate commercial viability, E3 Lithium will also be testing third-party technology at its field pilot plant this summer and fall. Based on the results of testing, commercial readiness and economics, the Company will decide which technology to pursue for its first commercial facility. Choosing the appropriate technology path for the first plant will enable E3 Lithium to get to commercial operations as quickly as possible and reduce its project technology risk while controlling the cost and quality of the process and end product.

Each of the KPIs outlined above will be compared relative to each other. For example, a higher recovery may offset lower lithium in the product stream. E3 Lithium believes that achieving these KPIs will facilitate a design basis for the Pre-Feasibility Study and provide a viable commercial operation. The Company is working through the full process design for a Pre-Feasibility Study and the fulsome project economics will be outlined, taking into account the DLE results, along with the other process factors, to produce a final battery quality lithium hydroxide.

“Achieving the KPIs we have outlined for our field pilot will provide us, our investors and stakeholders confidence in our ability to commercialize our vast, world-class resource,” said Chris Doornbos, President and CEO of E3 Lithium. “We look forward to proving the producibility and economics of our project and setting ourselves firmly on the path from development to commercialization.”

Pilot Progress Update

E3 Lithium began receiving pilot equipment to site in early June in advance of mechanical construction, planned for late June/early July. Once mechanical and electrical construction is complete, the Company will move into commissioning set to begin later in July.
